Detailed ways

The embodiments of the present invention will be further described below with reference to the accompanying drawings.

In the prior art, the reason why the plug and socket of the electrical connector assembly can only be inserted and separated in one direction is due to the contacts used in the plug and socket to a certain extent. The main reason is that the plug-in structure (plug-in hole, plug-in slot, plug-in seam, etc.) of the female contact has only one socket. A single socket is inserted in a single path. Therefore, if one wants to solve the problem that the electrical connector cannot realize multi-directional insertion and separation, it is necessary to first consider the modification of 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 insertion and separation by redesigning the structure form of the contact piece.

Figure 1 shows Embodiment 1 of the contact piece of the present invention. As shown in the figure, the contact piece is a reed-type contact piece, which is called a reed-type contact piece here. The hole-type contacts are distinguished. The reed-type contacts are made by stamping and punching as a whole, and their main components include two reeds 11 and a top plate 12 connected between the tops of the two reeds 11, which is called the top plate here. 12. In fact, in order to form the two reeds 11, the bending portion formed when the base material is bent is formed. Of course, in other embodiments, in the case of complicated manufacturing process, the top plate 12 and at least one There may also be a welded structure between the sheets 11 . The two reeds 11 are arranged side by side, and their fronts together form a plug-in structure for the mating contact to be inserted and electrically connected with it. 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-in structure is for the mating contact to be inserted, rather than being inserted into the mating contact.

The top plate 12 is provided with a notch 121. The notch 121 is formed by punching on the top plate 12, and its function cooperates with the corresponding positioning block to limit the front and rear movement of the contact piece relative to the corresponding insulator. Regarding the specific function of the notch 121, The following will be described in detail with reference to FIG. 2 , using an example of the use of the contact piece.

As can be seen from FIG. 1 , the front part of each reed 11 is provided with a band-like structure 111 that extends from top to bottom and is raised inwardly, and the band-like structure 111 constitutes a contact piece for engaging with the mating contact piece. The inserted part contacts and conducts the contact part. In this embodiment, there are two contact portions on each reed 11, and the two contact portions are arranged side by side. In this embodiment, the contact portion of the strip-shaped structure 111 is formed by punching the base material. Of course, in other embodiments, the contact portion can also be fabricated separately when the manufacturing process is slightly more complicated. , and then fixed on the reed 11 by welding. In addition, in addition to the belt-like structure, the contact part can also adopt a convex structure. This convex structure does not require the substrate to be cut, but only to bulge the reed inward by punching to form bubbles. like structure.

As shown in FIG. 1 , the front part of the reed 11 , that is, the part that forms the plug-in structure, is not closed at the top, front and bottom, and the top plate 12 does not extend to the front end of the reed 11 , so that the insertion The top, front and bottom of the connecting structure all have the conditions to serve as sockets 101 for inserting mating contacts. As a result, the plug-in structure forms sockets in different directions, and the number of sockets 101 can be selectively used as two. Of course, all three sockets can also be activated as required. In this way, when the mating contacts are plugged in, the number of sockets 101 is equal to the number of selectable plug-in paths. However, in this embodiment, pins 13 are provided at the lower rear of the reed 11, and the pins 13 are used to cooperate with the corresponding printed boards, so that the contacts are applied to the on-board connector. , the printed board will interfere with the insertion of the adapter contacts 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 has only Two sockets 101. It should be pointed out that, when using the two sockets with this arrangement, the mating contacts can not only be selectively inserted from the two sockets, but also can float in two directions after insertion. For example, it can be Float up and down and back and forth.

As mentioned above, the notch 121 on the top plate 12 is used to cooperate with the corresponding positioning block to limit the forward and backward movement of the contact piece relative to the corresponding insulator, and in the actual application process, in addition to being unable to move forward and backward, the contact piece can of course also move forward and backward. It cannot move up and down, otherwise when it is plugged with the matching contact, the position of the contact will change, resulting in the problem of unreliable plugging. In order to avoid this problem, the lower side of the reed is set to have the function of stopping and cooperating with the corresponding insulator. Of course, in other embodiments, the barb structure may also be provided on the spring, and the contact member may be fixed through the cooperation of the barb structure and the groove in the corresponding insulator.

In addition to the contact piece, its constituent parts also include Insulator 21 , positioning block 22 and guide pin 23 . The insulator 21 is provided with a contact piece installation slot 211 and a positioning block installation slot 212. The contact piece installation slot 211 is a through slot that runs through the front and rear with the opening facing downward, and the left and right sides of the slot walls are also provided with front and rear extending guide slots 213 , after the contact pieces are loaded into the corresponding contact piece installation grooves from the back to the front, the notch on the top plate is facing the positioning block installation groove 212 on the insulator. After the positioning block 22 is snapped into the positioning block installation groove, its At the same time, it is snapped into the notch on the top plate of the contact piece, so that the forward and backward movement of the contact piece can be limited; in addition, during the assembly process, the bottom of the reed is matched with the beam 215 on the bottom of the insulator, so that it can cooperate with the top of the insulator to define contact The up and down movement of the contact piece is achieved, thereby realizing the final fixation of the contact piece. The top of the insulator 21 is also provided with an opening structure 214 at the position corresponding to the top socket of the contact piece, so that the mating contact piece can be inserted and separated from the contact piece from the front or the top. The guide pins 23 are fixed on the insulator 21 to realize the positioning and connection between the insulator 21 and the corresponding printed board.
