Description

{Receptacle connector and plug connector}

The present application relates to a receptacle connector and a plug connector, and more particularly, to a receptacle connector and a plug connector having improved structures of a B2B connector (board to board connector) having RF (Radio Frequency) performance.

Board-to-board connectors are used to connect printed circuit boards (PCBs) or electronic components with patterned conductors. In particular, board-to-board connectors (B2B connectors) include plug connectors and receptacle connectors, each of which is connected to a different board, and by combining the plug connector and the receptacle connector, signal transmission through different boards can be enabled.

In order to electrically connect the contacts of the plug connector and the contacts of the receptacle connector, the plug connector and the receptacle connector are physically joined, but there is a risk that the receptacle connector or the plug connector may be damaged by pressure during this joining process. Therefore, a method is required to facilitate the joining between the receptacle connector and the plug connector and to improve its strength.

In addition, various shield structure connectors are being proposed to prevent abnormal operation of surrounding components due to electromagnetic waves generated during recent RF (Radio Frequency) signal transmission, or RF signal transmission interference due to electromagnetic waves applied from the outside.

Specifically, as disclosed in Drawing 1 of Patent Publication No. 10-2018-0081441, etc., in the past, when at least one of a terminal adjacent to a first ground terminal and a terminal adjacent to a second ground terminal facing the first ground terminal is made to function as a signal terminal, a structure capable of reducing crosstalk that may occur between terminals facing each other in a shield plate was provided. However, in the case of such a structure, there exists a problem in that the effect of reducing crosstalk of the terminals in the connector external direction is not sufficiently provided.

However, when describing preferred embodiments of the present invention in detail, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the same reference numerals are used throughout the drawings for parts that perform similar functions and actions.

In addition, throughout the specification, when a part is said to be 'connected' to another part, this includes not only the case where it is 'directly connected' but also the case where it is 'indirectly connected' with another element in between.

FIG. 1 is a schematic diagram showing the combination of a receptacle connector and a plug connector according to one embodiment of the present invention. As shown in FIG. 1, a plug connector (200) can be inserted into a receptacle connector (100) and electrically connected. Here, the plug connector (200) and the receptacle connector (100) can be board-to-board connectors, and when connected, a first contact (120) of the plug connector (200) formed in a two-row pattern and a second contact (220) of the receptacle connector (100) can form contact with each other to transmit a signal. Hereinafter, a receptacle connector and a plug connector according to one embodiment of the present invention will be described respectively.

Figure 2 is an exploded perspective view showing a receptacle connector (100) according to one embodiment of the present invention.

Referring to FIG. 2, a receptacle connector (100) according to one embodiment of the present invention may include a receptacle insulator (110), a first contact (120), and a receptacle shield portion (130).

The receptacle insulator (110) may be made of a non-conductive insulating material such as plastic, and the first contact (120) and the receptacle shield portion (130) may be combined within the receptacle insulator (110). Here, the receptacle insulator (110) may be manufactured by insert molding, including the first contact (120) and the receptacle shield portion (130), and depending on the implementation, the receptacle insulator (110) may be manufactured first by injection molding, and then the first contact (120) and the receptacle shield portion (130) may be assembled into the receptacle insulator (110).

Here, the receptacle insulator (110) may include a body portion (111), a groove portion (112), and a raised portion (113), as illustrated in FIG. 2. That is, the bar-shaped body portion (111) may include a groove portion (112) formed concavely on an upper surface (S1), and a raised portion (113) may protrude within the groove portion (112). A counterpart, such as a plug connector (200), may be inserted into the groove portion (112), and may form an electrical contact with the receptacle connector (100) within the groove portion (112).

The plurality of first contacts (120) may be made of a conductive material such as metal, and may form a contact portion (121) exposed within the home portion (112), as illustrated in FIG. 3.

Here, the contact portion (121) is provided for electrical connection with the counterpart, and the first contacts (120) can be electrically connected by forming a contact point with the counterpart through the contact portion (121). According to an embodiment, as shown in FIGS. 2 and 3, the contact portion (121) can be formed by bending the first contacts (120) along the raised portion (113) and the widthwise inner wall (I11, I12) of the body portion (111) so as to be exposed within the groove portion (112).

In this case, each of the first contacts (120) can form multiple contact points with the counterpart inserted into the home portion (112), so that the electrical connection with the counterpart can be stably maintained. Here, the multiple first contacts (120) exposed in the home portion (112) can be arranged at a predetermined pitch, respectively.

Meanwhile, the first contact (120) may further include a substrate connection portion (C1) for electrical connection with a substrate (not shown). As illustrated in FIG. 5, at the lower end of the width-wise outer wall (O11, O12), one end of a plurality of first contacts (120) may be exposed through the width-wise outer wall (O11) of the body portion (111), and then the first contacts (120) may be fixed to the substrate by a method such as soldering.

A circuit pattern may be formed on a substrate (not shown), and other electronic components mounted on the substrate and a receptacle connector (100) may be electrically connected by the circuit pattern. The substrate may be implemented in various types, such as a PCB (Printed Circuit Board) and an FPCB (Flexible Printed Circuit Board), and depending on the embodiment, a multilayer substrate including a plurality of layers may be used. In addition, the substrate may be coupled to an electronic device.

The receptacle shield portion (130) may be formed of a metal material and may be formed to cover the receptacle insulator (110). That is, the receptacle shield portion (130) may be provided to reinforce the strength of the receptacle insulator (110), and may perform guiding of the counterpart when coupled with the counterpart, depending on the embodiment. As illustrated in FIG. 2, the receptacle shield portion (130) may be coupled to the receptacle insulator (110) to guide movement of the counterpart, and may prevent the receptacle insulator (110) from being damaged by impact or pressure applied by the counterpart.

Specifically, the receptacle shield portion (130) may include an inner wall protection portion (131), a raised portion protection portion (132), an outer wall protection portion (133), and a contact protection portion (134), as illustrated in FIG. 2.

The inner wall protection part (131) may include width-wise inner wall protection parts (131A, 131B) that cover the width-wise inner walls (I11, I12) of the body part (111), and length-wise inner wall protection parts (131C, 133D) that cover the length-wise inner walls (I13, I14), and the raised portion protection part (132) may cover the length-wise inner wall (R1) of the raised portion (113). That is, the breakage strength can be strengthened when connecting with a counterpart such as a plug connector (200) by using the inner wall protection part (131) and the raised portion protection part (132).

The outer wall protection unit (133) may include a width-wise outer wall protection unit (133A, 133B) that covers the width-wise outer walls (O11, O12) of the body unit (111) and a length-wise outer wall protection unit (133C, 133D) that covers the length-wise outer walls (O13, O14). A contact protection unit (134) may be connected to the width-wise outer wall protection units (133A, 133B). Here, the outer wall protection unit (133) and the contact protection unit (134) may perform an electromagnetic shielding function as well as prevent damage to the receptacle insulator (110). That is, since the width-wise outer wall protection parts (133A, 133B) and the contact protection part (134) are positioned adjacent to a plurality of first contacts (120), it is possible to effectively shield electromagnetic waves that may occur in the first contacts (120). At this time, the contact protection part (134) can be grounded and connected to the substrate.

The contact protection member (134) may protrude in the width direction (X) of the body part (111) to cover the upper portion of the substrate connection part (C1), as illustrated in FIGS. 2 and 3. That is, in order to shield electromagnetic waves radiating from the first contact (120), the contact protection member (134) may be formed to cover one end of the first contact (120) included in the substrate connection part (C1). At this time, the contact protection member (134) may be formed to protrude further in the width direction (X) by a first set interval (D1) or more than the substrate connection part (C1). That is, as shown in FIGS. 5 and 7, when comparing the length (DA) of the first contact (120) exposed at the substrate connection portion (C1) and the length (DB) of the contact protection portion (134), the contact protection portion (134) can be formed to be at least longer than the first set interval (D1).

In addition, the contact protection member (134) may be formed to protrude horizontally in the width direction (X) at the first set height (H1), and may then be bent downward. Specifically, the contact protection member (134) may be divided into a horizontal portion (134A), a connecting portion (134B), and a vertical portion (134C). Here, the horizontal portion (134A) may be connected to the outer wall protection member (133) and may be horizontally protruded in the width direction (X). In addition, the connecting portion (134B) may be connected to the horizontal portion (134A) and may be bent downward, and the vertical portion (134C) may be connected to the connecting portion (134B) and may have a shape that extends vertically. That is, as shown in FIGS. 6 and 7, the contact protection part (134) may have a cross-section in the shape of the letter “ㄱ”, and at this time, the height of the contact protection part (134) corresponds to the first set height (H1).

Depending on the embodiment, the contact protection member (134) may include a plurality of openings (A1), as illustrated in FIGS. 4 and 6, and may be formed at positions corresponding to the substrate connection portions (C1) of the first contacts (120) exposed in each opening (A1). Accordingly, when mounting the receptacle connector (100) on a substrate, it is possible to confirm whether one end of each first contact (120) is accurately connected to the substrate through the openings (A1).

In addition, the contact protection member (134) may include a plurality of flange parts (flanges, B1) distinguished by openings (A1), and at this time, each flange part (B1) may be ground-connected on the substrate. That is, since the ground-connected points can be increased, a more effective electromagnetic shielding effect can be implemented. Depending on the embodiment, it is also possible to ground-connect the longitudinal outer wall protection members (133C, 133D).

Additionally, in Fig. 1, the contact protection part (134) is illustrated as being connected to the width-wise outer wall protection part (133A, 133B), but depending on the embodiment, it is also possible to manufacture it separately and apply it.

Meanwhile, as illustrated in FIG. 8, a receptacle insulator (110), a first contact (120), and a receptacle shield portion (130) can be combined to form a receptacle connector (100) according to one embodiment of the present invention.

Figure 9 is an exploded perspective view showing a plug connector (200) according to one embodiment of the present invention.

Referring to FIG. 9, a plug connector (200) according to one embodiment of the present invention may include a plug insulator (210), a second contact (220), and a plug shield portion (230).

The plug insulator (210) may be made of a non-conductive insulating material such as plastic, and the second contact (220), plug shield portion (230), etc. may be combined within the plug insulator (210). Here, the plug insulator (210) may be manufactured by insert molding, including the second contact (220) and the plug shield portion (230), and depending on the implementation example, the plug insulator (210) may be manufactured first by injection molding, etc., and then the second contact (220) and plug shield portion (230) may be assembled into the plug insulator (210).

Here, the plug insulator (210) may include a bar-shaped body portion (211) as illustrated in FIG. 9, and a recessed portion (212) formed concavely on an upper surface (S2) of the body portion (211). A counterpart, such as a raised portion (113) of a receptacle connector (100), may be inserted into the recessed portion (212), and the counterpart, such as a receptacle connector (100), may form an electrical contact with the plug connector (200) within the recessed portion (212).

A plurality of second contacts (220) can be made of a conductive material such as metal, and can form a contact portion (221) exposed to the outside, as shown in FIG. 9.

Here, the contact portion (221) is provided for electrical connection with the counterpart, and the second contacts (220) can be electrically connected by forming a contact point with the counterpart through the contact portion (221). Depending on the embodiment, as shown in FIGS. 9 and 10, it is also possible to form the contact portion (221) by exposing the second contacts (220) by bending along the widthwise inner wall (I21, I22) and the widthwise outer wall (O21, O22) of the body portion (211).

In this case, since each of the second contacts (220) can form multiple contact points with the counterpart, the contact portion (221) can maintain an electrical connection with the counterpart more stably. Here, the multiple second contacts (220) exposed at the contact portion (221) can be arranged at a predetermined pitch.

Meanwhile, the second contact (220) may further include a substrate connection portion (C2) for electrical connection with a substrate (not shown). As illustrated in Fig. 10, at the lower end of the widthwise outer wall (O21, O22), one end of a plurality of second contacts (220) may be exposed through the widthwise outer wall (O21, O22) of the body portion (211), and then the second contacts (220) may be fixed to the substrate by a method such as soldering.

A circuit pattern may be formed on a substrate (not shown), and other electronic components mounted on the substrate and a plug connector (200) may be electrically connected by the circuit pattern. The substrate may be implemented in various types, such as a PCB (Printed Circuit Board), an FPCB (Flexible Printed Circuit Board), and, depending on the embodiment, a multilayer substrate including a plurality of layers may be used. In addition, the substrate may be coupled to an electronic device.

The plug shield portion (230) may be formed of a metal material and may be formed to cover the plug insulator (210). That is, the plug shield portion (230) may be provided to reinforce the strength of the plug insulator (210), and, depending on the embodiment, may perform guiding for the counterpart when combined with the counterpart. As illustrated in FIG. 9, the plug shield portion (230) may be combined with the plug insulator (210) to guide movement of the counterpart and prevent the plug insulator (210) from being damaged by impact or pressure applied by the counterpart.

Specifically, the plug shield portion (230) may include an inner wall protection portion (231), an outer wall protection portion (232), and an outer shield wall (233), as illustrated in FIG. 9.

The inner wall protection part (231) can cover the longitudinal inner wall (I23, I24) of the body part (211), and the outer wall protection part (232) can include a width-wise outer wall protection part (232A, 232B) that covers the width-wise outer wall (O21, O22) of the body part (211), and a length-wise outer wall protection part (232C, 232D) that covers the length-wise outer wall (O23, O24).

The outer shield wall (233) may be provided to shield electromagnetic waves radiated from the second contact (220), and may have a shape that is spaced apart from the plug insulator (210) in the width direction (X) and extends in the length direction (Y) of the plug insulator (210), as illustrated in FIG. 9. That is, in order to shield electromagnetic waves radiated from the second contact (220), the outer shield wall (233) may be formed to cover the second contacts (220). At this time, as illustrated in FIGS. 12 to 14, the outer shield wall (233) may be positioned to be spaced apart from the substrate connecting portion (C2) by a second set interval (D2) or more in the width direction (X). That is, when comparing the length (DC) of a section in which the second contact (220) is exposed and the distance (DD) between the second contact (220) and the outer shield wall (231), the outer shield wall (233) can be formed to be spaced apart by at least the second set distance (D2).

Specifically, the outer shield wall (233) can be divided into a bridge (bridge, 233A) and a shield wall portion (233B). The bridge (233A) can be connected from the outer wall protection portion (232A, 232B) and can extend in the width direction (X). Here, the length of the bridge (233A) can be determined according to the size of the counterpart into which the plug connector (200) is inserted, etc. However, the length of the bridge (233A) can be determined so that the shield wall portion (233B) connected to the bridge (233A) is spaced apart in the width direction by a second set interval (D2) or more from the substrate connection portion (C2) of the second contact (220).

The shield wall portion (233B) may have a second set height (H2) and may be formed to extend in the longitudinal direction (Y). Here, the length of the shield wall portion (233B) may correspond to the length of the body portion (211), and the cross section of the shield wall portion (233B) may have an inverted U shape.

Specifically, the shield wall portion (233B) can be divided into a first shield wall member (E1), a second shield wall member (E2), and a connecting member (E3). That is, the first shield wall member (E1) and the second shield wall member (E2) can be positioned spaced apart from each other, and the connecting member (E3) can connect the first shield wall member (E1) and the second shield wall member (E2) by bending them. In this case, the cross section of the shield wall portion (223B) can have an inverted U shape.

In addition, depending on the embodiment, the shield wall portion (233B) may be implemented to have an inverted U-shaped cross-section by bending the flat body connected to the bridge (233A) toward the body portion (211). Here, when the cross-section of the shield wall portion (233B) is implemented in an inverted U-shape, the bonding strength can be increased when combined with the substrate, and the effect of the electromagnetic shielding function can be increased.

Additionally, the shape of the shield wall portion (233B) in the shape of an inverted U can prevent damage to the outer shield wall (233) that may occur when connecting with the receptacle connector (100), as illustrated in FIG. 16. For example, even when the plug connector (200) is forcibly inserted into the receptacle connector (100) in a misaligned state, the plug connector (200) can be guided by the inverted U shape of the shield wall portion (233B). Therefore, even in the case of an abnormal connection, it can be connected accurately by self-aligning by the inverted U shape.

In some embodiments, it is also possible to implement the thickness of the flat body to be thinner than the thickness of the bridge (233A). In this case, molding is easy during the manufacturing of the shield wall portion (233B), and the overall weight of the plug connector (100) can be reduced. In addition, it is also advantageous for miniaturization of the product. In some embodiments, the thickness ratio of the bridge (233A) and the flat body can be set to 2:1.

Additionally, the second set height (H2) of the shield wall portion (233B) can be set to be lower than or equal to the height (HA) of the second contacts (220), as illustrated in FIG. 14. If the second set height (H2) of the shield wall portion (233B) is higher, excessively strong pressure may be applied to the shield wall (233B) when abnormally connected, which may cause problems such as damage to the outer shield wall (233). Therefore, by setting the second set height (H2) of the shield wall portion (233B) to be lower than or equal to the height (HA) of the second contacts (220), the contact portions (120, 220) of each connector can be made into contact first when mated with the receptacle connector (200). That is, by distributing the pressure applied during insertion to each contact portion (120, 220), the load that can be applied to the outer shield wall (233) can be minimized.

Meanwhile, the shield wall portion (231B) may include a plurality of openings (A2) penetrating the shield wall portion (231B) in the width direction (X). Here, the openings (A2) may be formed at positions corresponding to the second contacts (220), respectively. According to an embodiment, during insert molding, the openings (A2) may be used to include a plurality of second contacts (220) within the body portion (211), and when mounting the plug connector (200) on a substrate, the openings may be used to confirm the mounting positions of the second contacts (220).

In addition, the shield wall portion (233B) may include a plurality of protrusions (B2) distinguished by openings (A2) as illustrated in FIGS. 10 to 12, and at this time, each of the protrusions (B2) may be ground-connected on the substrate. That is, since the number of points of ground connection can be increased, the electric shielding effect by the outer shield wall (230) can be enhanced.

Additionally, the shield wall portion (231B) may further include a fixing portion (L) bent in an L shape at the longitudinal (Y) end. Here, since the fixing portion (L) is implemented in an L shape, it is possible to secure a sufficient area for soldering. Accordingly, by fixing the fixing portion (L) to the substrate by soldering, the fastening strength of the shield wall portion (231B) to the substrate can be strengthened. In particular, the fixing portion (L) can reinforce the fastening strength corresponding to an external force in the longitudinal (Y) direction.

In addition, referring to FIG. 9, the outer shield wall (230) is illustrated as extending from the width-wise outer wall protection members (232A, 232B), but depending on the embodiment, it may also be extended from the length-wise outer wall protection members (232C, 232D). According to another embodiment, it is also possible to manufacture and apply the outer shield wall (230) separately from the outer wall protection member (232).

Meanwhile, as illustrated in FIG. 15, a plug insulator (210), a second contact (220), and a plug shield portion (230) can be combined to form a plug connector (200) according to one embodiment of the present invention.

Figures 16 and 17 are drawings showing the combination of a receptacle connector and a plug connector according to one embodiment of the present invention.

Referring to FIG. 16, a receptacle connector (100) and a plug connector (200) according to one embodiment of the present invention may include a structure for minimizing the width size of a combined connector module.

Specifically, when combining a receptacle connector (100) and a plug connector (200), the raised portion (113) of the receptacle connector (100) can be inserted into the groove portion (212) of the plug connector (200), and at this time, the shield wall portion (233B) of the plug connector (200) can be overlapped on the contact protection portion (134) of the receptacle connector (100). That is, when each of the contact protection portions (134) and the shield wall portion (233B) is spaced apart from each other in the width direction (x-axis direction) and does not overlap, it is possible to reduce the width size of the combined connector module.

In addition, the first set height (H1) of the contact protection portion (134) and the second set height (H2) of the shield wall portion (233B) may be each distributed from the preset overall fastening height. That is, the height of the first set height (H1), the second set height (H2), and the buffer height (not shown) may be set to be the overall fastening height. In this case, despite the overlapping of the contact protection portion (134) and the shield wall portion (233B), it is also possible to minimize the length in the thickness direction.

Additionally, the receptacle connector (100) and the plug connector (200) according to one embodiment of the present invention may further include a structure for reinforcing a fastening force. Specifically, as illustrated in FIGS. 16 and 17, the inner wall protection portion (131) or the outer wall protection portion (133) of the receptacle connector (100) may include a protrusion (P), and the plug connector (200) may include an insertion groove (Q) at a position corresponding to the protrusion (P), respectively. That is, the protrusion (P) of the receptacle connector (100) may be inserted into the insertion groove (Q), thereby increasing the fastening force between the plug connector (200) and the receptacle connector (100). Here, the insertion groove (Q) may be formed through coining processing, etc.

FIG. 18 is a schematic diagram showing the results of an experiment on EMI (Electro Magnetic Interference) shielding performance according to the presence or absence of a receptacle shield portion (130) and a plug shield portion (230) for a receptacle connector (100) and a plug connector (200) according to one embodiment of the present invention.

Fig. 18(a) is an experimental result showing EMI shielding performance when equipped with a receptacle shield part (130) and a plug shield part (230). When the receptacle connector (100) and the plug connector (200) are combined, the dark blue parts on both sides mean that the electric field is low, indicating that electromagnetic waves are blocked well.

On the other hand, Fig. 18(b) is a comparative example, which corresponds to a case where the receptacle shield part (130) and the plug shield part (230) are not provided in the receptacle connector (100) and the plug connector (200), respectively. Here, when the receptacle connector (100) and the plug connector (200) are coupled, both sides appear in sky blue, which means that the electric field is relatively high compared to dark blue. That is, when the receptacle connector (100) and the plug connector (200) are not provided with the receptacle shield part (130) and the plug shield part (230), it indicates that electromagnetic wave blocking is not performed well.

The present invention is not limited to the above-described embodiments and the attached drawings. It will be apparent to those skilled in the art to which the present invention pertains that components according to the present invention can be substituted, modified, and changed within a scope that does not depart from the technical spirit of the present invention.
