Detailed ways

This embodiment involves a connector and an electronic device using the connector. The following briefly describes the concepts involved in the embodiment:

A connector generally refers to an electrical connector, that is, a device used to connect two active devices. After the connector is connected to the two active devices, current or signals can be transmitted between the two active devices.

Crosstalk: mainly refers to the coupling phenomenon between two signal lines. Due to the close spatial distance of the signal lines, there will be inductive and capacitive coupling between the two, which will interfere with each other. As the transmission rate of the signal transmitted by the connector increases, a certain crosstalk phenomenon may occur between the signal lines of the connector, which affects the integrity of signal transmission. Therefore, reducing and reducing the signal crosstalk and loss in the connector is one of the problems to be solved urgently in the connector design.

FIG. 2 is a schematic diagram of a connection between a shield and an electrical contact module in a connector provided by an embodiment of the present application. FIG. 3 is a schematic structural diagram of an electrical contact module in a connector provided by an embodiment of the present application. FIG. 4 is a schematic cross-sectional view of a connector provided in an embodiment of the present application in a plugging direction. FIG. 5 is a schematic diagram of the arrangement of signal contacts and ground contacts in a connector provided by an embodiment of the present application. FIG. 6 is a schematic structural diagram of a ground shielding sheet in a connector provided by an embodiment of the present application. As shown in FIGS. 1 to 6 , the connector in this embodiment specifically includes a conductive shield 1 and at least one electrical contact module 2 . Each electrical contact module 2 includes at least one signal contact piece 21 , at least one ground contact piece 22 and at least one ground shielding piece 23 . The grounding shielding piece 23 is arranged on the sides of the signal contact piece 21 and the grounding contact piece 22 . The signal contact piece 21 is insulated from the ground shielding sheet 23, and the grounding contact piece 22 and the grounding shielding sheet 23 are electrically connected; the signal contact piece 21 includes a signal pin 211 located in the plug-in area of the connector, and the shielding element 1 and the grounding shielding sheet 23 are connected to each other, The shielding member 1 is provided with an accommodating area, the signal pins 211 pass through the accommodating area, and the signal pins 211 and the shielding member 1 are not electrically connected.

In the above connectors, each electrical contact module 2 may have two different connection ends. Exemplarily, one of the connection ends of the electrical contact module 2 may be connected to a device such as a single board, and the other connection end may be used for and Devices such as backplanes are connected to realize electrical connection and signal transmission between the two devices.

Wherein, each electrical contact module 2 can relatively independently implement electrical connection between devices. Therefore, the number of the electrical contact modules 2 in the connector can be one or more than one, and the number of the electrical contact modules 2 can be changed according to the number and specifications of the devices that need to be electrically connected. Exemplarily, each electrical contact module 2 can be connected to a row or a column of pins on a device to be connected.

Specifically, each electrical contact module 2 includes a signal contact piece 21 , a ground contact piece 22 and a ground shielding sheet 23 . The signal contacts 21 are used for signal transmission, and the ground contacts 22 are used for ground isolation and shielding. In order to perform functions such as signal transmission or grounding shielding, both the signal contact piece 21 and the ground contact piece 22 may have various structures and types. For example, in an optional implementation manner, the signal contact piece 21 may be a signal trace, and the ground contact piece 22 may be a ground wire, or both the signal contact piece 21 and the ground contact piece 22 may be sheet or Commonly used conductive connection structures such as plate. In this embodiment, the signal contacts 21 are used as signal wirings, and the ground contacts 22 are used as ground wires as an example for description.

In order for the connector to realize electrical connection between two devices, one end of the signal contact piece 21 and the ground contact piece 22 will protrude from one of the connection ends of the connector, and form a signal contact point and a ground contact point (the signal contact point and the ground contact point 22). The ground contact point can be a fish-eye structure), and the other ends of the signal contact piece 21 and the ground contact piece 22 are located at the other connection end of the connector, and form a signal pin 211 and a ground pin 221 . The signal pin 211 and the ground pin 221 can be inserted into another connector, and the area where the signal pin 211 and the ground pin 221 are located is the insertion area of the connector. Wherein, since the connector may be a male connector or a female connector, as an optional embodiment, the signal pin 211 may be one of a male pin or a female pin.

In order to complete the transmission of one or more signals, the corresponding signal contacts 21 may be correspondingly one or more. And the signal contacts 21 may be differential signal contacts, or may be other types of signal contacts. Exemplarily, the signal contacts 21 are differential signal contacts. In this case, a plurality of signal contacts 21 may be arranged in pairs, and each pair of signal contacts 21 may be used to transmit a differential pair of signals.

Optionally, each electrical contact module 2 may have multiple ground contacts 22 , and the number of ground contacts 22 may match the number of signal contacts 21 , for example, when the signal contacts 21 are differential signal contacts 21, a pair of signal contacts 21 for transmitting a differential pair of signals and a ground contact 22 cooperate with each other, and the ground contact 22 can be located between the two signal contacts 21 or between the two signal contacts 21. The side of the contact piece 21 .

Optionally, the signal contacts 21 and the ground contacts 22 in each electrical contact module 2 may be arranged side by side in sequence. For example, the electrical contact module 2 may have a plate-like or sheet-like structure as a whole, and the signal contacts 21 and the ground contacts 22 on the electrical contact module 2 may be arranged side by side in sequence along the direction of the board surface.

In order to avoid a short circuit between the ground contact 22 and the signal contact 21 , the ground contact 22 and the signal contact 21 need to be relatively insulated. Specifically, the signal contact piece 21 and the ground contact piece 22 may be arranged at intervals so that there is a certain distance between the signal contact piece 21 and the ground contact piece 22 , or the signal contact piece 21 and the ground contact piece 22 may be arranged an insulator to achieve insulation isolation between the signal contact piece 21 and the ground contact piece 22 .

The ground shielding sheet 23 is located on the side of the ground contact piece 22 and the signal contact piece 21 , and is connected to the ground contact piece 22 in a conductive manner. Wherein, the ground shielding sheet 23 may be a plate-like or sheet-like structure, and at this time, the grounding shielding sheet 23 may cover the sides of the ground contact 22 and the signal contact 21 , thereby providing electromagnetic shielding for the signal contact 21 in the lateral direction.

In the electrical contact module 2 of this embodiment, the signal contact piece 21 and the ground contact piece 22 may be alternately arranged with the ground shielding sheet 23 at intervals. Specifically, the connector includes at least two electrical contact modules 2 arranged side by side, and the signal contacts 21 and ground contacts 22 in the two electrical contact modules 2 are alternately arranged with the ground shielding sheet 23, that is, the signal contacts The layer formed by 21 and the ground contact 22 may be sandwiched between two ground shielding sheets 23 , or the ground shielding sheet 23 may be sandwiched between two layers formed by the signal contact 21 and the ground contact 22 . In this way, the grounding shielding sheet 23 can provide better grounding shielding on the side of the signal contact piece 21 , thereby reducing the phenomenon of signal crosstalk between two adjacent electrical contact modules 2 .

However, on the one hand, due to the limitation of the size and quantity of the grounding shielding sheet 23, the grounding shielding effect of the grounding shielding sheet 23 on the signal contacts 21 adjacent to the edge of the grounding shielding sheet 23 in the electrical contact module 2 is poor; on the other hand, , since the ground shielding sheet 23 is arranged on the side of the electrical contact module 2, it is difficult to realize the ground shielding of each signal contact piece 21 in the single electrical contact module 2, and the same between the signal contacts 21 in the single electrical contact module 2 Signal crosstalk may occur; lastly, poor contact may also occur between the ground shielding sheet 23 and a single ground contact 22 , so signal crosstalk may still occur on the signal contact 21 .

At this time, in order to further improve the anti-signal crosstalk performance of the connector, the connector also includes a shielding member 1, and the shielding member 1 is located on the side of the plug-in area of the connector, that is, the signal pin 211 and the grounding pin 221. one end. On the other hand, the shielding element 1 and the ground shielding sheet 23 are electrically connected. In this way, through the connection of the shielding member 1, the grounding contact members 22 and the grounding shielding sheet 23 in the different electrical contact modules 2 are connected to each other and connected as a whole. On the one hand, a single grounding contact member 22 and the grounding shielding sheet 23 are effectively avoided. The phenomenon of poor contact occurs between them, and more importantly, making multiple grounding contacts 22 and grounding contact pieces in the same network is equivalent to increasing the distribution of the grounding network, and the return current of the signal needs to pass through the grounding network. The increased distribution of the network is equivalent to increasing the return path of the return current, so that all signal pairs have a complete and closest return path, which can reduce the radiation effect of the electric field, thereby reducing the crosstalk between the signals and suppressing the impedance difference. Insertion loss resonance caused by matching and electric field radiation generated by signal oscillation.

Meanwhile, the shielding member 1 is provided with a hollow accommodating area, and the signal pins 211 of the signal contact member 21 pass through the accommodating area, and the signal pins 211 and the shielding member 1 are not electrically connected. Specifically, the signal pins 211 and the shielding member 1 may be insulated from each other, and unless otherwise specified, the mutual insulation between the signal pins 211 and the shielding member 1 is taken as an example for description. The signal pins 211 and the shielding member 1 may be spaced apart or isolated from each other by other insulators, so as to avoid electrical connection such as conduction and contact between the signal pins 211 and the shielding member 1 .

At this time, when the shielding member 1 and the grounding shielding sheet 23 are connected and conducting, since the shielding member 1 is provided with an accommodating area, the signal pins 211 can pass through the shielding member 1 from the accommodating area without being affected by the shielding member 1. The structure of the shielding element 1 interferes, or is in contact with and conducts with the shielding element 1 . By setting the accommodating area on the shielding member 1, on the one hand, the signal pins 211 can normally extend to the outside of the connector and be plugged with other connectors or devices; on the other hand, the single signal pin on the electrical contact module 2 can be 211 is at least partially in the accommodating area, and the outside of the accommodating area is a structure formed by the shielding element 1, so the signal pin 211 will be shielded and protected by the outer shielding element 1 in the circumferential direction of the signal pin 211, effectively improving its own The ability to resist signal crosstalk.

Various possible structures and specific implementations of various parts in the connector, such as the shielding member 1 and the electrical contact module 2, will be described in detail below.

Specifically, for the shielding member 1 , since the shielding member 1 needs to be electrically connected to and grounded with the grounding shielding sheet 23 and the grounding contact member 22 , the shielding member 1 itself is a conductive conductor. Optionally, the shielding member 1 may specifically be a metal member, a plastic member with electroplating on the surface or a conductive plastic member, or other materials with electrical conductivity well known to those skilled in the art, so that the surface of the shielding member 1 has good electrical conductivity. When the grounding contact piece 22 and the grounding shielding piece 23 are in contact with the shielding piece 1, they can conduct with each other.

When the signal pins 211 of the signal contacts 21 pass through the accommodating area, the signal pins 211 can be insulated from the shielding member 1 in various ways. As an optional implementation manner, the signal pins 211 of the signal contact member 21 may be suspended in the accommodating area of the shield member 1 .

Among them, in order to keep the insulation between the signal pin 211 and the shield 1, the signal pin 211 can be suspended in the accommodating area, and the shield 1 and the signal pin 211 do not contact each other, but pass through the air isolation. Since air is a good insulating medium, the signal pins 211 and the shielding member 1 can also be insulated from each other. At the same time, the shielding member 1 and the signal pins 211 do not need to be connected by other components, and the overall structure of the connector is relatively simple and reliable, which is convenient for processing and manufacturing.

In addition, in other optional embodiments, an insulating member may also be provided on the outer side of the signal pin 211, and the insulating member and the shielding member 1 are relatively fixed, so that the signal pin 211 can be fixed to the shielding member 1 through the insulating member. In the accommodating area, at the same time, because the insulating member itself has the insulating ability, there will be no short circuit between the signal pin 211 and the shielding member 1 .

Wherein, in order to fix the insulating member on the shielding member 1 , the insulating member can be connected to the shielding member 1 by abutting, snap-fitting, interference fit or other connection methods commonly used by those skilled in the art. The specific structure and shape of the insulating member can be set according to the size and shape of the accommodating area, which is not limited here. Exemplarily, the insulating member may surround the circumferential outer side of the signal pin 211 .

Optionally, the insulating member may be made of insulating material, for example, the insulating member may be a plastic member or a resin member.

In order to form the above-mentioned accommodating area, optionally, the shielding member 1 may include an accommodating cavity 11 , and an accommodating area for the signal pin 211 to pass through is formed inside the accommodating cavity 11 , and a cavity for accommodating the cavity 11 There is a space between the wall and the signal pins 211 .

Wherein, only the signal pins 211 may pass through the interior of the accommodating cavity 11, that is, the signal pins 211 are suspended in the air. At this time, no other spacer is set between the cavity wall of the accommodating cavity 11 and the signal pins 211, but the The gap between the two achieves insulation. Alternatively, in addition to the signal pins 211 , an insulating member may also be provided inside the accommodating cavity 11 , and the signal pins 211 are kept relatively fixed and insulated from the cavity wall of the accommodating cavity 11 through the insulating member.

In order to allow the signal pins 211 to pass through the accommodating cavity 11, the accommodating cavity 11 may be a cavity with an opening, that is, both ends of the accommodating cavity 11 along the axial direction of the signal pins 211 are provided with openings, and the signal pins 211 are provided with openings. The feet 211 can enter and exit through the two openings, thereby penetrating the accommodating cavity 11 . On the other hand, the cavity wall of the accommodating cavity 11 is located at the side of the signal pin 211 and realizes shielding and grounding functions.

At this time, the cavity wall of the accommodating cavity 11 can be surrounded on the outer side of the signal pin 211 in the circumferential direction. For example, as an optional accommodating cavity structure, the entire circumference of the signal pin 211 can be accommodated. The cavity wall of the cavity 11 is enclosed. FIG. 7 is an optional structural schematic diagram of an accommodating cavity in a shield provided by an embodiment of the present application. As shown in FIG. 7 , at this time, the outer sides of the signal pins 211 in different circumferential directions are surrounded by the accommodating cavity 11 , so that the cavity wall of the accommodating cavity 11 can form a closed shield in the circumferential direction of the signal pins 211 Therefore, the omnidirectional shielding of the signal pin 211 in the circumferential direction is realized, which has better shielding and signal crosstalk reduction effects.

In another optional accommodating cavity structure, a part of the circumferential direction of the signal pin 211 may be surrounded by the cavity wall of the accommodating cavity 11 . FIG. 8 is another optional structural schematic diagram of the accommodating cavity in the shield provided by the embodiment of the present application. As shown in FIG. 8 , specifically, in the accommodating cavity 11 of this structure, the accommodating cavity 11 has an opening at the lateral position of the signal pin 211 , so that the cavity wall of the accommodating cavity 11 will be outside the opening. Realize the signal shielding of the signal pin 211. For example, openings may be provided at the sides of the accommodating cavity 11 , so that only a part of the circumferential direction of the signal pins 211 is surrounded by the accommodating cavity 11 , and the positions of the corresponding openings are not shielded. In this way, on the one hand, the shielding effect of the signal pin 211 is affected by the size of the opening and the location of the opening, so the signal pin 211 can have special shielding effect and characteristics through different opening sizes and shapes; After the opening is provided on the component 1, the structure at the opening can be used in cooperation with other structures on the shielding component 1 or other components of the connector, such as fixing the shielding component 1 on the connector through the opening. The size and shape of the opening of the accommodating cavity 11 can be set according to the structure and actual needs of the shielding member 1 .

And with the different structures of the accommodating cavity 11 , the accommodating cavity 11 can also be of various types. For example, when the signal pin 211 is surrounded by the cavity wall of the accommodating cavity 11 in the circumferential direction, the accommodating cavity 11 can be a through hole, and the signal pin 211 can be formed from the two end faces of the through hole. The direction runs through the through hole, and the hole wall of the through hole is arranged on the side of the signal pin 211 and maintains a certain interval with the signal pin 211 .

Wherein, the through hole can be a straight hole, and the through hole can have the same cross-sectional size at each position in the axial direction, so that each section of the signal pin 211 in the through hole and the through hole wall can be kept relatively suitable Even if the through hole has a long axial length, the signal pin 211 will not touch the hole wall of the through hole, so that the insulation performance is relatively reliable.

When only a part of the signal pin 211 in the circumferential direction is surrounded by the cavity wall of the accommodating cavity 11 , correspondingly, the accommodating cavity 11 may be in the form of a through slot or the like. At this time, the extending direction of the through slot is the same or similar to the axial direction of the signal pin 211 , and the notch of the through slot is located on the side of the signal pin 211 , thereby forming the opening of the accommodating cavity 11 . The axial direction of the signal pin 211 is the extension direction or the length direction of the signal pin 211 .

Similar to the through hole, the through slot can also be a straight slot, and the cross-sections of each part of the through slot along the circumferential direction of the through slot have the same size.

When the accommodating cavity 11 is a through hole or a through slot, as an optional method, the extension direction of the through hole or the through slot can be the same as the extension direction of the signal pin 211 . In this way, the axial direction of the signal pin 211 will be parallel to the extending direction of the through hole or the through slot, so a constant distance is always maintained between the signal pin 211 and the cavity wall of the through hole or through slot, even if the length of the signal pin 211 Longer, the signal pin 211 will not touch or interfere with the hole wall of the through hole or the slot wall of the through slot, which avoids the phenomenon that the signal pin 211 is connected to the shielding member 1 due to skew.

In addition, optionally, the cross-sectional shape of the accommodating cavity 11 in the shielding member 1 in the direction perpendicular to the length of the signal pin 211 can be various shapes. Exemplarily, the cross-sectional shape of the accommodating cavity 11 perpendicular to the axial direction of the signal pin 211 may be a rectangle, a circle, an ellipse, or the like. In this way, the cross-sectional shape of the accommodating cavity 11 is relatively regular and symmetrical, and the distance between the signal pins 211 and the cavity wall of the accommodating cavity 11 is relatively uniform. In this embodiment, the cross-sectional shape of the accommodating cavity 11 is taken as an example for description.

It should be noted that when the accommodating cavity 11 is a through hole, the cross section of the through hole is the cross-sectional shape of the accommodating cavity 11 in this direction. When the accommodating cavity 11 is a through slot, the shape enclosed by the opening edge of the through slot can be defined as the cross-sectional shape of the accommodating cavity 11 in the direction perpendicular to the length of the signal pin 211 .

In the connector, there may be a plurality of signal contacts 21 in the electrical contact module 2 to transmit different signals correspondingly. Correspondingly, when there are multiple signal contacts 21 , there will also be multiple signal pins 211 , and there may be a large distance between different signal pins 211 . At this time, a single accommodating cavity 11 will have the following defects : First, it may be difficult for a single accommodating cavity 11 to accommodate multiple signal pins 211 at the same time; secondly, multiple signal pins 211 are located in the same accommodating cavity 11, and the accommodating cavity 11 has a large internal space, so the signal leads 211 There may be a relatively large distance between the pins 211 and the cavity wall of the accommodating cavity 11 , thereby affecting the shielding effect of the shielding member 1 on the signal pins 211 . Therefore, in order to avoid the above-mentioned defects, as an optional implementation manner, the number of accommodating cavities 11 in the shielding member 1 is at least two, and the accommodating cavities 11 are arranged at intervals along the radial direction of the signal pins 211 .

Wherein, when there are multiple signal contacts 21, the multiple signal contacts 21 can be arranged side by side, and correspondingly, the signal pins 211 on the signal contacts 21 are also arranged side by side. At this time, setting the number of the accommodating cavities 11 to more than one can allow a plurality of signal pins 211 to pass through different accommodating cavities 11 on the shielding member 1 respectively. The accommodating cavities 11 of the shielding member 1 are arranged at intervals along the radial direction of the signal pins 211 , that is, in a direction perpendicular to the axial direction of the signal pins 211 , so that the plurality of signal pins 211 arranged side by side pass through the positions respectively. The accommodating cavity 11 is opposite to each other, so that there is a suitable distance between the signal pin 211 and the cavity wall of the accommodating cavity 11, and the accommodating cavity 11 can have a relatively reasonable size and shape.

When the number of the electrical contact modules 2 is greater than one, in order to provide functions such as shielding for the plurality of electrical contact modules 2 at the same time, the shielding member 1 may also have different types and structures accordingly.

For example, in an optional structure, the connector may include a shielding member 1, and the shielding member 1 corresponds to a plurality of electrical contact modules 2 at the same time and realizes the shielding function. At this time, the shielding member 1 may have at least two accommodating cavity groups, the accommodating cavity groups and the electrical contact modules 2 are arranged in a one-to-one correspondence, and the different accommodating cavity groups are arranged at intervals along the first direction, wherein the first direction and the electrical contact module 2 are arranged at intervals. The extending directions of the signal pins 211 are perpendicular to each other.

When a plurality of electrical contact modules 2 are included in the connector, only one shield 1 may be included in the connector, and the electrical contact modules 2 are all connected to the shield 1 . At this time, in order to avoid and shield the signal pins 211 in different electrical contact modules 2 , at least two accommodating cavity groups are provided on the shielding member 1 , and each accommodating cavity group corresponds to a signal pin of the electrical contact module 2 . 211. Wherein, each accommodating cavity group may have one or more accommodating cavities 11 , and these accommodating cavities 11 may pass through the signal pins 211 in the power supply contact module 2 . Among them, since there may be a large number of signal contacts 21 in the electrical contact module 2, correspondingly, each accommodating cavity group may include more than one accommodating cavity 11, and make the same electrical contact module 2 The signal pins 211 on a plurality of different signal contacts 21 pass through a plurality of different accommodating cavities 11 .

Because a plurality of electrical contact modules 2 can be arranged in parallel, correspondingly, in order to be connected to each electrical contact module 2 correspondingly, a plurality of accommodating cavity groups are arranged at intervals along the same direction. Exemplarily, the accommodating cavity groups may be arranged along a first direction perpendicular to the extending direction of the signal pins 211 . In this way, a plurality of electrical contact modules 2 are also arranged side by side along the first direction, and these electrical contact modules 2 are located on the same side relative to the shielding member 1 and maintain the same relative height and distance from the shielding member 1 . Through this arrangement, in the electrical contact module 2, the signal pins 211 of the signal contacts 21 can all extend to the side of the shielding member 1, and the signal pins 211 of the signal contacts 21 in the electrical contact module 2 can also be connected to the shield 1 side. The corresponding accommodating cavity groups are opposite to each other and pass through the accommodating cavity 11 of the accommodating cavity group, so as to obtain the shielding of the shielding member 1 and improve the anti-signal crosstalk capability of the signal pins 211 .

The intervals between the accommodating cavity groups may be the same or different, and the specific interval may be determined according to the size and type of the electrical contact module 2, which is not limited here.

When the accommodating cavity group includes more than one accommodating cavity 11, in order to keep the appropriate distance between each accommodating cavity 11 in the same accommodating cavity group and each signal pin 211 in the electrical contact module 2, optional , the accommodating cavity group may include at least two accommodating cavities 11 spaced along the second direction. It should be noted that both the first direction and the second direction are located in a plane perpendicular to the extending direction of the signal pins 211 , and the first direction and the second direction are also perpendicular to each other.

Specifically, in the electrical contact module 2 , the signal contacts 21 are sequentially spaced along a certain direction, so that the signal pins 211 corresponding to the signal contacts 21 are also spaced and arranged side by side along the direction. Therefore, corresponding to the arrangement of the signal pins 211 , the respective accommodating cavities 11 in the same accommodating cavity group may also be arranged at intervals along the arrangement direction of the signal pins 211 . At this time, the second direction may be determined as the spacing direction of the signal pins 211 in the same electrical contact module 2 .

In the case where the electrical contact module 2 is generally a thin-layer structure, a plurality of electrical contact modules 2 can be arranged side by side along the thickness direction of the electrical contact module 2; and the arrangement direction of the signal pins 211 in each electrical contact module 2 will be along the direction of the thickness of the electrical contact module 2. The plane direction where the electrical contact module 2 is located is a direction perpendicular to the thickness direction of the electrical contact module 2 . Therefore, it is easy to know that since the arrangement direction of the accommodating cavity 11 corresponds to the arrangement direction of the signal pins 211, the accommodating cavity 11 will also be along the second direction perpendicular to the first direction, that is, the electrical contact The plane directions where the modules 2 are located are arranged at intervals.

In this embodiment, when the shielding member 1 in the connector is connected to a plurality of electrical contact modules 2 at the same time, and the set of accommodating cavities corresponding to each electrical contact module 2 on the shielding member 1 includes more than one container with the same number When the cavities 11 are placed, the respective accommodating cavities 11 in the shielding member 1 may be arranged in a regular matrix. Correspondingly, the overall structure of the shielding member 1 may be square or the like.

However, those skilled in the art can understand that when the connector includes multiple electrical contact modules 2, different electrical contact modules 2 may have different signal connection methods, so different electrical contact modules 2 may have different numbers of signal leads feet 211. Correspondingly, among the multiple accommodating cavity groups provided on the shielding member 1 , different accommodating cavity groups may also include accommodating cavities 11 with different arrangements and structures. Exemplarily, the number of accommodating cavities 11 included in different accommodating cavity groups on the shield 1 may be different. It includes 4 accommodating cavities 11; it can also be that the number of accommodating cavities 11 included in different accommodating cavity groups on the shield 1 is the same, but the accommodating cavities 11 have different sizes, for example, one accommodating cavity group The size and size of the accommodating cavity 11 are smaller than those of the accommodating cavity 11 in other accommodating cavity groups; or the number and size of the accommodating cavity 11 in different accommodating cavity groups on the shield 1 are the same, but the The accommodating cavities 11 in the accommodating cavity group have different intervals, resulting in different accommodating cavity positions in different accommodating cavities 11; At least two of the number of 11 , the size of the accommodating cavity 11 , and the position of the accommodating cavity 11 are different, so that accommodating cavity groups with different arrangements are formed in the shielding member 1 , which will not be repeated here.

In a plurality of accommodating cavity groups in the shielding element 1, different accommodating cavity groups have the same or different arrangement and structure, so that the shielding element 1 can be connected to a plurality of the same or different types of electrical contact modules 2, so that the connector Meet a variety of different types and specifications of wiring.

However, if the connector includes only one shield 1, and a plurality of electrical contact modules 2 are connected to the shield 1, the shield 1 can be used as a common connection end and a common support structure of the plurality of electrical contact modules 2 to connect The structural integrity of the device is good, and it has high structural strength and high reliability.

In another optional embodiment, there may also be a plurality of shielding elements 1 in the connector, and the plurality of electrical contact modules 2 are respectively connected to different shielding elements 1 . Wherein, in the connector of this embodiment, the number of shielding members 1 may be the same as the number of electrical contact modules 2 , the electrical contact modules 2 are arranged side by side, and the position of the shielding member 1 corresponds to the position of the electrical contact module 2 .

Specifically, when there are multiple electrical contact modules 2 in the connector, each electrical contact module 2 can also be connected to a corresponding shielding member 1 . Exemplarily, similar to the embodiment in which a plurality of electrical contact modules 2 are connected to the shielding member 1, the electrical contact modules 2 can also be arranged in parallel, and each electrical contact module 2 is connected to a signal pin 211 at a location. The independent shielding element 1 , that is, each electrical contact module 2 completes the shielding function through an independent shielding element 1 . In this way, each shielding member 1 is set independently, and a single shielding member 1 has a small volume, so that the setting and use of the shielding member 1 are more flexible, and the adjustment is convenient.

At this time, since a plurality of electrical contact modules 2 are arranged in parallel, correspondingly, the shielding members 1 corresponding to the electrical contact modules 2 one-to-one are also arranged in parallel. The shielding elements 1 can be connected to each other through the connection structure of the shielding elements 1 themselves, or after the shielding elements 1 are close to each other and arranged side by side, the fixing and interconnection can be completed by other fixing structures. The relative fixing manners between the shielding members 1 may be connection manners commonly used by those skilled in the art, such as abutment, snap connection, fastener connection, etc., which are not limited here.

Since the electrical contact module 2 can be a sheet or a thin-layer structure, correspondingly, the shielding member 1 corresponding to the electrical contact module 2 can be a strip-shaped structure, and the length direction of the shielding member 1 corresponds to the plane where the electrical contact module 2 is located. the same direction. At this time, when the shielding member 1 provides shielding for the signal pins 211 of the electrical contact module 2, the structure of the shielding member 1 will not cause too much influence on the side-by-side arrangement of the electrical contact modules 2. Multiple electrical contact modules in the connector A small distance can be maintained between 2, so that the structure of the connector is relatively compact.

When there are multiple shielding members 1 and they are in one-to-one correspondence with the electrical contact modules 2 , there may also be one or more accommodating cavities 11 on the shielding member 1 , which are in phase with the electrical contact modules 2 connected to the shielding member 1 . correspond. Specifically, similar to the embodiment in which a plurality of electrical contact modules 2 are connected to the shielding member 1 , in the electrical contact module 2 , each signal contact member 21 will be arranged at intervals along a certain direction, so that each signal contact member The signal pins 211 corresponding to 21 are also sequentially spaced and arranged in parallel along this direction. Therefore, when more than one accommodating cavity 11 is included in the same shielding member 1 , the accommodating cavities 11 may also be arranged at intervals along the arrangement direction of the signal pins 211 .

In addition, those skilled in the art can understand that when the connector includes multiple electrical contact modules 2, since different electrical contact modules 2 may have different signal connection methods, different electrical contact modules 2 may have different numbers of The signal pins 211, and correspondingly, the accommodating cavities 11 on different shields 1 in the connector may also include different arrangements and structures. Exemplarily, the number of accommodating cavities 11 included on different shielding elements 1 may be different; it may also be that the number of accommodating cavities 11 included on different shielding elements 1 is the same, but the accommodating cavities 11 have different sizes; or The number and size of the accommodating cavities 11 on different shielding elements 1 are the same, but the accommodating cavities 11 of different shielding elements 1 have different sizes of intervals and positions; alternatively, the accommodating cavities in different shielding elements 1 may also be At least two of the number of 11, the size of the accommodating cavity 11 and the position of the accommodating cavity 11 are not equal. The specific differences in their arrangement have been described in detail in the case where the connector includes a shielding member 1 , and will not be repeated here.

In addition, in addition to the above two methods, the connector may also include a plurality of shielding members 1, and the plurality of shielding members 1 include both the same shielding member 1 and the connection of a plurality of different electrical contact modules 2, and also include One shield 1 corresponds to the case where one electrical contact module 2 is connected. In this case, the specific structures of the shielding member 1 and the electrical contact module 2 in the connector may refer to the above two methods, which will not be repeated here.

In addition, the number of signal pins 211 that can be accommodated in the accommodating cavity 11 on the shielding member 1 can also be set according to the structure and usage requirements of the connector. For example, as an optional implementation manner, each accommodating cavity 11 is provided with at least two signal pins 211 .

Specifically, because the accommodating cavity 11 can provide shielding and protection in the circumferential direction of the signal pins 211 , even if the number of the signal pins 211 in the accommodating cavity 11 is greater than one, the accommodating cavity 11 can ensure that the signal pins are surrounded by the signal pins 211 . 211 in the circumferential direction, so that the signal of the signal pin 211 is shielded by the cavity wall of the accommodating cavity 11 . Therefore, the number of the signal pins 211 in each accommodating cavity 11 may be greater than one, for example, the number of the signal pins 211 in the accommodating cavity 11 is two or more. In this way, when the number of signal contacts 21 in the electrical contact module 2 is large, even if the space on the shield 1 is limited and the number of accommodating cavities 11 on the shield 1 is small, the signal pins 211 on the connector can be The shielding and protection functions of the accommodating cavity 11 are obtained.

Wherein, since in the electrical contact module 2, the signal contacts 21 can be used to transmit differential signal pairs, the signal contacts 21 in the electrical contact module 2 can be arranged in pairs. Correspondingly, as an optional structure, each accommodating cavity 11 on the shielding member 1 can also accommodate two signal pins 211 . At this time, the two signal pins 211 can be respectively used to transmit two different signals in a differential signal pair.

Specifically, two signal pins 211 are accommodated in the same accommodating cavity 11 , and the signals transmitted by the two signal pins 211 come from the same differential signal pair, that is, the two signal pins 211 transmit amplitudes respectively. Two signals of the same, but opposite polarity. Therefore, when the two signal pins 211 are located in the same accommodating cavity 11 , the mutual interference between the two signal pins 211 is small, so that the accommodating cavity 11 can better protect and shield the signal pins 211 , the mutual interference between the two signal pins 211 transmitting differential signals is small.

In the connector, however, each electrical contact module 2 itself can also have many different structures and types. For example, in the electrical contact module 2, the signal contact piece 21 needs to be insulated from the ground contact piece 22 and the grounding shielding sheet 23. Therefore, it needs to be provided inside the electrical contact module 2 for isolating the signal contact piece 21 from the ground contact piece 22, The structure of the ground shielding sheet 23 . Wherein, in an optional embodiment, the electrical contact module 2 includes an insulating support member 24 , and the insulating support member 24 is supported between the signal contact member 21 and the ground shielding sheet 23 .

Among them, since the grounding shielding piece 23 and the grounding contact piece 22 are connected to each other and grounded, and the grounding shielding piece 23 will cover the sides of the signal contact piece 21 and the grounding contact piece 22, the signal contact piece 21 and the grounding shielding piece 23 An insulating support member 24 with insulating properties may be disposed therebetween, so as to isolate and insulate the signal contact member 21 and the ground shielding sheet 23 from each other.

The insulating support 24 may be made of insulating material, for example, the insulating support 24 is made of non-conductive plastic material.

At this time, the signal contact piece 21 and the ground contact piece 22 can be respectively arranged at different positions on the ground shielding sheet 23, so that there is a gap between the signal contact piece 21 and the ground contact piece 22, and the signal contact piece 21 and the ground contact piece 22 can be realized by air. Insulation between the ground contacts 22; alternatively, the signal contacts 21 and the ground contacts 22 can also be insulated from each other by an insulator, for example, the insulation support 24 is used to realize the isolation between the signal contacts 21 and the ground contacts 22 isolation.

Wherein, the insulating support member 24 can also have a variety of different structures. For example, the insulating supporter 24 may partially or completely surround the outside of the signal contact 21 . At this time, the signal contact piece 21 is located inside the insulating support piece 24 , and the outside is protected and isolated by the insulating support piece 24 , and will not contact the ground contact piece 22 and the ground shielding sheet 23 .

Specifically, in order to surround the signal contact piece 21 , a cavity or groove may be provided on the insulating support member 24 , and the signal contact piece 21 can be placed into the cavity or groove, and communicate with the outer side of the insulating support piece 24 . The grounding contact piece 22 and the grounding shielding sheet 23 are isolated from each other, thereby preventing the signal contacting piece 21 from conducting with the grounding contacting piece 22 or the grounding shielding sheet 23 . Alternatively, the insulating support 24 can also be surrounded on the outside of the signal contact 21 by means of injection molding or the like, so as to realize the insulation between the signal contact 21 , the ground contact 22 and the ground shielding sheet 23 .

In addition, the insulating support member 24 can also be isolated only between the signal contact member 21 and the ground shielding sheet 23, and the signal contact member 21 and the ground contact member 22 are insulated from each other by setting a gap. Specifically, the signal contact member 21 may be provided with a fixing structure such as a positioning groove, so that the signal contact member 21 is fixed on the insulating support member 24 , and the insulating support member 24 and the ground contact member 22 are respectively fixed on different parts of the ground shielding sheet 23 . Location. In addition, the insulating contact piece can also be of other different structures and shapes, as long as the insulating contact piece can achieve insulation isolation between the signal contact piece 21 and the ground shielding sheet 23 and other components, which is not limited here.

In order to fix and isolate the signal contact piece 21 and the ground contact piece 22, optionally, the ground shielding sheet 23 may have an uneven surface. At this time, the ground shielding sheet 23 has a plurality of raised areas 231 in a direction perpendicular to its own thickness, and the raised areas 231 are arranged at intervals, so that a recessed area 232 can be formed between every two adjacent raised areas 231 . In this way, the signal contact piece 21 and the ground contact piece 22 can be respectively arranged in different regions on the ground shielding sheet 23 .

Wherein, the signal contact piece 21 may be arranged in the recessed area 232 of the grounding shielding sheet 23 , and the grounding contact piece 22 may be arranged at the convex area 231 of the grounding shielding sheet 23 . Since the installation directions of the grounding shielding sheet 23 and the entire electrical contact module 2 are parallel to each other, the signal contact piece 21 is arranged in the recessed area 232 of the grounding shielding sheet 23, and the signal contact piece 21 is formed by the concave-convex structure of the grounding shielding sheet 23 itself. Therefore, the exposure of the signal contact piece 21 is reduced, so that the signal insulation piece has more reliable insulation performance.

Specifically, both the recessed area 232 and the raised area 231 on the ground shielding sheet 23 may extend along the length direction of the signal contact piece 21 or the ground contact piece 22 , so as to conform to the shape of the signal contact piece 21 or the ground contact piece 22 shape and size. In this way, the concave area 232 and the convex area 231 on the grounding shielding sheet 23 can limit and fix the signal contact piece 21 or the ground contact piece 22 depending on its own shape.

In order to realize the fixation between the ground shielding sheet 23 and the shielding member 1, optionally, the edge of the grounding shielding sheet 23 facing the shielding member 1 has a shape that matches the shielding member 1, and the grounding shielding sheet 23 and the shielding member 1 Abut.

At this time, since the edge of the grounding shielding sheet 23 will abut with the shielding member 1 and achieve a conductive connection, when the shape of the edge of the grounding shielding sheet 23 facing the shielding member 1 matches the shape of the surface of the shielding member 1, the grounding shielding The contact surface between the sheet 23 and the shielding member 1 will extend in different directions. Even if the grounding shielding sheet 23 is displaced and moved in a certain direction relative to the shielding member 1, the grounding shielding sheet 23 can still be in contact with the shielding member 1. keep in contact with each other. At the same time, the contact portion of the ground shielding sheet 23 that can be in contact with the shielding member 1 has a longer length and a larger contact area, which can achieve effective conduction between the grounding shielding sheet 23 and the contact member.

Exemplarily, since the shielding member 1 is provided with an accommodating cavity 11, and the accommodating cavity 11 is in the shape of a through hole or a through groove, accordingly, the edge shape of the ground shielding sheet 23 may be uneven, and the The outwardly protruding edge can extend into the interior of the accommodating cavity 11 ; the concave edge is located at the outer part of the accommodating cavity 11 and abuts against the outer surface of the shielding member 1 .

Specifically, in an optional implementation manner, the edge of the ground shielding sheet 23 facing the shielding member 1 has at least two protruding parts arranged at intervals, and the protruding parts protrude into the corresponding accommodating cavity 11 and connect with the corresponding accommodating cavity 11 . The cavity walls of the accommodating cavity 11 are in contact. The size and shape of the protruding portion can be matched with the shape of the accommodating cavity 11, for example, the width of the protruding portion and the size of the accommodating cavity 11 can match each other, so that the protruding portion can be snapped into the interior of the accommodating cavity 11, etc. .

In addition, the edge of the ground shielding sheet 23 facing the shielding member 1 may also be in other different shapes, for example, the edge of the grounding shielding sheet 23 may have a snap-fit structure capable of being connected to the shielding member 1, etc., which is not limited here.

In order to support structures such as the electrical contact module 2 and the shielding member 1, and at the same time allow the connector to be plugged normally, optionally, the connector may further include an insulating base. FIG. 9a is a schematic diagram of the front structure of the insulating base in the embodiment of the present application. FIG. 9b is a schematic view of the structure of the reverse side of the insulating base in the embodiment of the present application. FIG. 10 is a schematic structural diagram of a connector with an insulating base in an embodiment of the present application. As shown in Fig. 9a, Fig. 9b and Fig. 10, the connector further includes an insulating base 3, and the insulating base 3 is arranged outside the plug-in area of the connector.

Specifically, the entire insulating base 3 may be in a semi-enclosed housing structure, so as to protect the electrical contact module 2 and the shielding member 1 . Specifically, the insulating base 3 may be composed of one or more frame members 31 . The frame member 31 surrounds the electrical contact module 2 and the outer side of the shield member 1, and the inner side of the frame member 31 faces the electrical contact module 2 and the shield member 1, and the outer side of the frame member 31 faces the structure or the mating connection with the connector. device. When the insulating base 3 is composed of a plurality of frame-shaped members 31 , the plurality of frame-shaped members 31 can be arranged side by side, and the position of each frame-shaped member 31 corresponds to one electrical contact module 2 .

Wherein, because the insulating base 3 is located outside the plug area of the connector, in order not to affect the normal plug connection of the signal contact piece 21 and the ground contact piece 22 in the connector, the frame member 31 in the insulating base 3 may include There are avoidance holes 311 for the signal pins 211 or other pins to pass through. In this way, the signal pin 211 can pass through the avoidance hole 311 and be supported and fixed by the hole wall of the avoidance hole 311 . The avoidance holes 311 are opposite to the signal pins 211 and the ground pins 221 on the connector, so that the signal pins 211 and the ground pins 221 can be penetrated from the inner side of the frame member 31 to the outer side of the frame member 31 . Optionally, the avoidance holes 311 may be provided in a one-to-one correspondence with these pins. Exemplarily, the avoidance holes 311 may be arranged in an array on the insulating base 3 .

In order to be insulated from other components, the insulating base 3 is made of insulating material. Optionally, structures such as the frame member 31 in the insulating base 3 may be made of insulating plastic. Exemplarily, the insulating base 3 may be formed of materials such as liquid crystal polymer (LCP) by injection molding.

The component includes signal pins located in the insertion area of the connector, the shielding component and the grounding shielding sheet are in conduction, the shielding component is provided with an accommodating area, and the signal pins pass through the accommodating area. area, and the signal pins are insulated from the shield. In this way, through the connection of the shielding members, the grounding contact members and the grounding shielding sheets in different electrical contact modules are connected to each other and connected as a whole, which increases the return path of the return current, thereby reducing the crosstalk between signals and suppressing the Insertion loss resonance caused by impedance mismatch and electric field radiation generated by signal oscillation, and improve the ability to resist signal crosstalk.
