An embodiment of the present utility model provides an electrical connector 100. As shown in fig. 1 and 2, the electrical connector 100 includes: the female seat 1 and the male seat 2 which is in plug-in fit with the female seat 1. The male holder 2 and the female holder 1 respectively include a plurality of conductive plates 21 and a plurality of conductive terminals 11 arranged at intervals along the length extending direction of the male holder 2 and the female holder 1. The conductive terminal 11 includes two opposite side clamping plates 111, and contact convex surfaces a are disposed on the two side clamping plates 111. When the male seat 2 and the female seat 1 are plugged, the two side clamping plates 111 clamp and fix the conductive plate 21, and the two contact convex surfaces a are matched and abutted against two sides of the conductive plate 21 and are electrically connected with the conductive plate 21.

First, as shown in fig. 1, the female socket 1 and the male socket 2 include a female base 12 and a male base 22, respectively, in addition to the conductive terminals 11 and the conductive plates 21, respectively. The female base 12 and the male base 22 may be respectively used for mounting and carrying a plurality of conductive terminals 11 and a plurality of conductive plates 21, so that respective parts of the female base 1 and the male base 2 may be assembled to form a single body. The material of the female base 12 and the male base 22 is an insulating material, for example, plastic. In addition, the female base 12 and the male base 22 have related structures for mating and plugging with each other, so that the female base 1 and the male base 2 can be plugged together when the electrical connector 100 is in use.

Second, the electrical connector 100 may be used to connect a battery to a circuit board, with the male mount 2 being disposed on the battery and the female mount 1 being disposed on the circuit board. Under the condition that the female seat 1 and the male seat 2 are connected in an inserting mode, a circuit between the battery and the circuit board is conducted, and the battery supplies power to the circuit board. Specifically, in some embodiments, as shown in fig. 3, in order to facilitate alignment and buckling between the female base 1 and the circuit board, a plurality of positioning posts 13 are disposed on the female base 1. Correspondingly, the circuit board is provided with mounting holes matched with the positioning posts 13.

An electrical connector 100 according to an embodiment of the present utility model, as shown in fig. 1 and 2, includes: the female seat 1 and the male seat 2 which is in plug-in fit with the female seat 1. The male holder 2 and the female holder 1 respectively include a plurality of conductive plates 21 and a plurality of conductive terminals 11 arranged at intervals along the length extending direction of the male holder 2 and the female holder 1. The conductive terminal 11 includes two opposite side clamping plates 111, and contact convex surfaces a are disposed on the two side clamping plates 111. When the male seat 2 and the female seat 1 are plugged, the two side clamping plates 111 clamp and fix the conductive plate 21, and the two contact convex surfaces a are matched and abutted against two sides of the conductive plate 21 and are electrically connected with the conductive plate 21. In this way, when the electrical connector 100 is in use, the male socket 2 and the female socket 1 are plugged, the conductive plate 21 is inserted between the two side clamping plates 111 of the conductive terminal 11, the conductive plate 21 is clamped and fixed by the two side clamping plates 111, and the two contact convex surfaces a are matched and abutted against two sides of the conductive plate 21, so that the two side clamping plates 111 are electrically connected with the conductive plate 21. When the conductive plate 21 is inserted into the two side clamping plates 111 of the conductive terminal 11, the conductive plate 21 presses the inner sides of the two side clamping plates 111 of the conductive terminal 11, and the two side clamping plates 111 elastically deform outwards, so that the two side clamping plates 111 can apply a certain clamping force to the conductive plate 21 under the action of elastic potential energy, and the two side clamping plates 111 clamp and fix the conductive plate 21. Since the contact surface a of the side clamping plates 111 is designed to be convex, the elastic deformation amount of the two side clamping plates 111 is increased, so that the clamping force is increased, and the stability and the firmness of the connection between the conductive plate 21 and the conductive terminal 11 are improved. In addition, the pressing force of the outer sides of the two side clamping plates 111 against the inner wall of the female socket 1 is correspondingly increased, so that the connection between the conductive terminal 11 and the female socket 1 is more compact.

In some embodiments, as shown in fig. 2 and 6, the side clamping plate 111 of the conductive terminal 11 is L-shaped, and the contact convex surface a on the side clamping plate 111 is also L-shaped. This not only increases the contact area between the conductive plate 21 and the conductive terminal 11, but also further increases the stability and the firmness of the connection therebetween.

In some embodiments, as shown in fig. 2, the conductive terminal 11 is in an integrally formed structure, and the integrally forming process is simple and convenient to manufacture.

With continued reference to fig. 2, the conductive terminal 11 further includes: a U-shaped connection plate 112 and two support plates 113. The U-shaped connection plate 112 includes a connection portion 1121 and two oppositely disposed lateral support portions 1122. The two support plates 113 are disposed opposite to each other on the two lateral support portions 1122. The two side clamping plates 111 are respectively provided on the two support plates 113. The conductive terminal 11 is U-shaped as a whole, and has simple design structure and simple and convenient manufacture. .

As will be seen with continued reference to fig. 2 and 4, the distance between the two support plates 113 becomes smaller from the end near the lateral support portion 1122 to the end near the side clamping plate 111 so that the distance between the two side clamping plates 111 is smaller than the distance between the two lateral support portions 1122. In this way, the elastic deformation amount of the two side clamping plates 111 to the outside is increased under the pressing of the conductive plate 21, so that the clamping force applied to the conductive plate 21 by the two side clamping plates 111 is increased, and the stability and the firmness of the connection between the conductive plate 21 and the conductive terminal 11 are further improved.

As seen in fig. 2 and 6, the end of both lateral support portions 1122 remote from the connecting portion 1121 is formed with barbs b. When the conductive terminal 11 and the female base 12 are assembled together, the end of the lateral support portion 1122 remote from the connecting portion 1121 abuts against a corresponding stopper on the female base 12, and the piercing tip of the barb b can be pushed toward the surface of the stopper. The conductive terminal 11 is prevented from coming out of the female base 12 by friction force of the piercing tip of the barb b and the surface of the stopper.

In some embodiments, as shown in fig. 2, the bottom of the U-shaped connection plate 112 is provided with a bottom notch 1123; the bottom notch 1123 is located partially at the connection 1121 and partially at the lateral support 1122. The bottom notch 1123 may serve to dissipate heat. Specifically, when the female socket 1 is disposed on the circuit board, the bottom of the U-shaped connection board 112 of the conductive terminal 11 is attached to the surface plane of the circuit board, the conductive terminal 11 is not in contact with the circuit board at the bottom notch 1123, and the conductive terminal 11 can ventilate and dissipate heat through the bottom notch 1123.

In the above embodiment, as shown in fig. 5 and 6, the female socket 1 has the insertion cavity 121 into which the conductive terminal 11 is inserted. The conductive terminal 11 is inserted into the insertion cavity 121 in the direction indicated by arrow a.

Specifically, in some embodiments, as shown in fig. 5 and 6, the jack cavity 121 has two insertion ports, an upper insertion port 1211a and a side insertion port 1211 b. Based on this, as shown in fig. 1, the male base 2 can be inserted and removed from both sides of the upper surface (direction indicated by arrow B) of the female base 1 and the side surface (direction indicated by arrow C) of the female base 1.

In some embodiments, as shown in fig. 5 and 6, the socket 121 is of a chamfer design at both the upper insertion port 1211a and the side insertion port 1211 b. When the conductive plate 21 is inserted into the female socket 1, the inclined plane of the chamfer design structure can play a guiding role, so that the conductive plate 21 is conveniently inserted into the female socket 1, the insertion force is reduced, the male socket 2 and the female socket 1 are conveniently inserted, and the electric connector 100 has the advantages of small insertion force and convenience in assembly.

Further, in some embodiments, as shown in fig. 5 and 6, a stop boss 1212 is provided at an upper side of the connection portion 1121 of the corresponding U-shaped connection plate 112 within the socket cavity 121; when the conductive terminal 11 is inserted into the insertion cavity 121, the upper side of the connecting portion 1121 abuts against the stopper boss 1212. When the conductive terminal 11 is inserted into the insertion cavity 121 in place, the upper side of the connecting portion 1121 is in a positive fit with the stop boss 1212. When the male holder 2 is pulled out from above the female holder 1, the stop boss 1212 may prevent the conductive terminal 11 from being moved upward.

In some embodiments, as shown in fig. 5 and 6, a stop 1213 is provided within the socket 121 at the end of the corresponding lateral support 1122 remote from the connection 1121; when the conductive terminal 11 is inserted into the insertion cavity 121, the end of the lateral support portion 1122 away from the connection portion 1121 abuts against the stopper 1213. When the conductive terminal 11 is inserted into the socket 121 in place, the end of the lateral support portion 1122 remote from the connection portion 1121 is in a positive fit with the stop block 1213. When the male housing 2 is pulled out from the side of the female housing 1, the stopper 1213 can prevent the conductive terminal 11 from being moved out sideways.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
