technical field

The invention relates to the field of electrical connectors, in particular to an electrical connector capable of multi-directional insertion and extraction and an electrical connector assembly.

Background technique

In the traditional electrical connector assembly, the insertion and separation between the plug and the socket have a single fixed direction, that is, when one of the plug and the socket is fixed, the other must be plugged or separated from it along a fixed direction. . The above-mentioned problems also exist in the electrical connector, which is the main electrical connection component between printed boards. In existing board-to-board connectors, usually after a mating direction is specified, the separation direction is determined accordingly, that is, the direction opposite to the mating direction, and mating and separation are limited to only one axial direction. However, in the field of communication, with the diversification of communication equipment, the connection between functional modules and motherboards (printed boards) is becoming more and more complicated. Separation, but requires that two printed boards that are parallel to each other can also be inserted in the direction perpendicular to their board surfaces, that is, the connector is required to have the function of multi-directional insertion and separation. However, the existing electrical connectors do not have the above functions.

Detailed ways

Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

In the prior art, the plug and socket of the electrical connector assembly can only be mated and separated in one direction. On the one hand, it is caused by the insulator (housing) used in the plug and socket, and on the other hand The reason, and the main reason, is caused by the contacts used in plugs and sockets. The reason is mainly because there is only one socket corresponding to the same internal contact on the insulator, and there is often only one socket for the same contact. Even if the exposed contact is used, due to its single socket structure, It is also impossible to realize multi-directional insertion and extension. When mating with the matching contact piece, the matching contact piece can only be inserted from a single socket with a single path. Therefore, if it is desired to solve the problem that the electrical connector cannot be mated and separated in multiple directions, it is necessary to consider changing the structure of the contact piece. The present invention starts from the structure of the contact piece, and provides a solution for solving the problem that the electrical connector cannot realize multi-directional mating and separation by redesigning the structural form of the contact piece.

FIG. 1 shows the first embodiment of the electrical connector of the present invention. It can be seen from the figure that the main components of the electrical connector include two parts: a contact 101 and an insulator 201 .

The contact 101 is a reed contact, which is called a reed contact here, mainly to distinguish it from a rod-shaped hole-type contact with a socket. The reed contact is formed by stamping and punching as a whole. , its main components include two reeds 11 and a top plate 12 connected between the tops of the two reeds 11, called the top plate 12 here, which is actually formed when the base material is bent to shape the two reeds 11 Of course, in other embodiments, the top plate 12 and at least one reed 11 may also be welded if the manufacturing process is relatively complicated. The two reeds 11 are arranged side by side, and their front parts together form a plug-in structure for inserting and conducting conductive connection with the matching contact piece. Obviously, the plug-in structure is a female-type plug-in structure, that is, when it is connected with When the mating contact is plugged, the plug structure is for the mating contact to be inserted, rather than inserted into the mating contact.

The top plate 12 is provided with a notch 121, which is formed by punching on the top plate 12, and its function cooperates with the positioning block 23 (see below) of the insulator 201 to limit the contact piece to move forward and backward relative to the insulator. Regarding the notch 121 The specific mode of action will be described in detail below in conjunction with FIGS. 1 and 2 .

As can be seen from Fig. 3, the front portion of each reed 11 is provided with a strip-like structure 111 that extends from top to bottom and bulges inward. The inserted part contacts and conducts the contact portion. In this embodiment, there are two contact portions on each reed 11 , and the two contact portions are arranged side by side. Here, the contact portion of the strip structure 111 is formed by punching the base material. Of course, in other embodiments, if the manufacturing process is slightly complicated, the contact portion can also be made separately, and then welded The structure fixed on the reed 11 by way. In addition, in addition to the strip-shaped structure 111, the contact part can also adopt a convex structure. This convex structure does not need to cut the base material, but only bulges the reed inward by punching to form Bubble structure is enough.

As shown in Figure 3, the front part of the reed 11, that is, the part that forms the plug-in structure, its top, front and bottom are not closed, and the top plate 12 does not extend to the front end of the reed 11, thus making the plug The top, front and bottom of the connection structure are all ready to serve as the socket 1001 for the insertion of the mating contact. As a result, the socket structure forms sockets in different directions. The number of sockets 1001 can be selectively two, and of course, all three sockets can be used as required. In this way, when mating contacts are plugged in, the number of sockets 1001 is equal to the number of selectable plugging paths. However, in this embodiment, pins 13 are provided at the rear and lower part of the reed 11, and the pins 13 are used to cooperate with corresponding printed boards, so that the contacts can be applied to onboard connectors. , the printed board will interfere with the insertion of the mating contact from the lower opening of the plug-in structure, so only the front opening and the top opening of the plug-in structure are considered to be used as sockets, that is, in this embodiment, the plug-in structure only There are two sockets 1001. It should be pointed out that when using the two sockets with this arrangement structure, the mating contact 301 can not only be selectively inserted from the two sockets, but also float in two directions after mating, for example, It can float up and down and forward and backward, and the arrows in Figure 5 show the direction of floating up and down.

In this embodiment, the insulator 201 is used directly as the housing of the electrical connector. Of course, in other embodiments, sometimes in order to ensure the electrical continuity of the shielding structure, a metal shield can also be provided outside the insulator so that the metal The shield together with the insulator 201 constitutes the housing of the electrical connector. As shown in Figure 4, the insulator 201 is provided with a contact mounting structure 21, which is to meet one of the most basic functions of the insulator 201, that is, to provide a base for the conductive contact 101 to be installed. Under the circumstances, the electrical isolation between different contacts is realized. As for the contact mounting structure 21, a structure similar to a hole is specifically adopted in this embodiment. Here, "similar to a hole" is said mainly because multiple sides of the contact mounting structure 21 adopt an open structure. , it does not constitute a hole in the true sense, but is actually close to a channel-like structure. It should be emphasized that the contact installation structure 21 does not refer to the sum of all structures that can be installed with contacts, but a contact installation The structure of the contact piece is specifically matched with the contact piece 101 one by one, that is, each structure that can install a contact piece constitutes a contact piece installation structure 21 . The front part of the contact mounting structure 21 constitutes a female socket part 211, and the function of the female socket part 211 is to insert the contacts of the adapter connector to make electrical contact with the contacts therein. Different directions are matched with the insertion of the adapter contact piece, and two sockets are arranged on the female socket part, and the orientations of the two sockets are different. Of course, based on the consideration of plugging and mating with the mating contacts from different directions, the number of sockets should not be limited to two, and the number can be three or more as required. In this embodiment, one of the two sockets faces forward to form a front socket 2111, and the other socket is located at one side of the female socket part to form a side socket 2112, where the side socket 2112 is specifically located at the female socket. The upper side of the part 211 forms an included angle of 90° with the orientation of the front socket. In use, the mating contact piece can be plugged and electrically conductive with the contact piece in the female socket part from the front side along the front-back direction or from the upper side along the up-down direction.

In order to be able to plug in with the matching contact piece smoothly, a guide structure is also set on the insulator. The guide structure can be a common guide structure or a separate guide structure. The so-called common guide structure means The contact piece with the connector is inserted from any socket and any direction, and it is guided by a set of common guide structures. This guide structure is suitable for situations where the number of sockets is relatively small and the arrangement is regular, such as In this example. The separate guide structure is suitable for the situation where the number of sockets is large and the distribution is irregular. Each guide structure can only play a guiding role in one direction or the insertion direction of some sockets, but cannot guide the insertion of all sockets. Orientation role. In this embodiment, the guide structure adopts a common guide structure, specifically a guide groove structure 22. The guide groove structure 22 is arranged on the front end surface of the insulator and is a vertically extending through groove. Whether it is inserted from the front socket along the front-to-back direction, or inserted from the side socket along the up-and-down direction, it can play a guiding role; of course, in other embodiments, the guiding structure can also adopt a ribbed guide column structure. The principle is the same as that of the guide groove structure described above, and will not be repeated here.

In order to facilitate the quick assembly of the contact piece, in this embodiment, the top of the insulator includes a limit block 23, the function of the limit block 23 is to limit the forward and backward movement of the contact piece, and it is detachable from other parts of the insulator. In this embodiment, it is specifically a clip-on structure. The clip-on structure is formed by the snap key 231 set on the side of the limit block and the hole wall of the corresponding hole on the insulator. The card slot matching the card key is realized. The limiting effect of the limiting block 23 on the contact is realized in this way: the inner surface of the limiting block 23 protrudes into the contact installation structure, and when the contact is installed in place, it protrudes to the contact through the inner surface of the limiting block. The parts in the component mounting structure can be snapped into the corresponding notch 121 provided on the contact component 101 , as shown in FIG. 2 . In this embodiment, there are four contact mounting structures 21 arranged side by side, and the limiting block 23 straddles each contact mounting structure. Of course, in other embodiments, the limiting block 23 can also be the same as the contact mounting structure. One-to-one relationship.

It has been mentioned above that the notch 121 on the top plate 12 is to cooperate with the corresponding positioning block to limit the forward and backward movement of the contact relative to the corresponding insulator. At the same time, as shown in Figures 1 and 2, the limit block 23 can be snapped into the gap 121 provided on the top of the contact piece, so as to further realize the locking of the front and rear positions of the contact piece. The limit on the up and down direction of the part is mainly realized by the cooperation of the top of the insulator and the bottom beam 24; in addition, the wall of the contact mounting structure 21 is also provided with a card slot 25. In this embodiment, the card slot 25 extends along the front and back directions, and it can lock the contact piece by cooperating with the barb structure provided on the contact piece; in order to connect reliably with the printed board, the bottom of the insulator is also provided with a guide pin 26 with a barb structure . After assembly, the mating contact can be inserted into the contact through the side socket on the top of the female plug structure or the front socket on the front. In practical application, apart from being unable to move back and forth, the contact cannot move up and down, otherwise, when it is plugged into the matching contact, the position of the contact will change, resulting in unreliable plugging. In order to avoid this problem, the underside of the tongue is provided with the function of a stop fit with a corresponding insulator. Of course, in other embodiments, the barb structure can also be provided on the reed, and the fixing of the contact piece can be realized through the cooperation of the barb structure with the groove in the corresponding insulator.

Embodiment 2 of the electrical connector of the present invention, as shown in FIG. 6 , differs from Embodiment 1 of the electrical connector in that in this embodiment, a barb structure 81 is provided on the reed of the contact piece, Through the barb structure 81 , it is possible to realize the limitation of the front and rear direction of the contact piece during installation.

In the above-mentioned embodiments, because the contacts are installed in a hidden manner, the insulator needs to be provided with a matching socket, but in other embodiments, the contacts can also be installed in the form of exposure, that is, the plug-in structure of the contacts is The exposed state is sufficient, and in this case, the structural form of the insulator is no longer limited.

Embodiment 1 of the electrical connector assembly, as shown in Figures 7-9, the electrical connector assembly includes a plug 501 and a socket 601, wherein the structure of the plug 501 is the same as that of the above-mentioned embodiment of the electrical connector, and is not described here. repeat. The socket 601 includes a socket insulator 61 and a socket contact 62. The installation form of the socket contact 62 to the socket insulator 61 is the same as the installation form of the contact and the insulator in the above-mentioned electrical connector. The difference from the plug 501 is that the socket contact 62 adopts It is a male contact, which has a plate-type inserting portion 621 that matches the inserting structure on the contact of the plug, and can be inserted into the inserting structure from any socket of the inserting structure. In addition, the socket insulator 61 is provided with a guide post 611 corresponding to the guide groove structure on the plug insulator, and the guide post 611 can be inserted into the guide groove structure from the opening or one end of the guide groove structure to achieve the purpose of guiding.

Embodiment 2 of the electrical connector assembly, as shown in FIG. 10 , the difference between this embodiment of the electrical connector assembly and the above-mentioned embodiment 1 of the electrical connector assembly is only that each edge of the socket contact part is The chamfering structure 91 is provided for smoother insertion with the female contact piece.
