With the rapid development and wide application of electronic technology, the market has increasingly higher requirements for the efficient transmission and stable operation of electrical connectors.

[0003] The contact member in an electrical connector is the core component for realizing the electrical connection function. The main function of the contact member is to ensure the reliability of electrical connection. It transmits the voltage or signal from the wires and cables connected to the tail of the connector to the corresponding contact member of the mating connector, and the performance of the contact member directly affects the electrical contact reliability of the connector.

[0004] In the prior art, for example, the patent application with the publication number CN101800372A discloses a contact member and an electrical connector. The contact member has a spring portion, and a pair of spring elements that can elastically move in a direction perpendicular to the axis. The spring elements have docking portions, and the docking portions are docked with each other by subsequent preloading. The spring elements have contact portions that contact the male contact member.

[0005] However, the above prior art has the following problems: after long-term use, the two spring elements on the spring portion are likely to separate from each other, resulting in the inability to clamp the male contact member. Summary of the Invention

[0006] The main object of the present invention is to provide a female contact member and an electrical connector, aiming to solve the above technical problems.

[0007] To achieve the above object, on the one hand, the present invention provides a female contact member, including an elastic member and two current-carrying members; the current-carrying members include plate body portions arranged vertically; the upper ends of the plate body portions are bent downward to form elastic contact portions; the lower ends of the plate body portions are horizontally bent toward the side where the elastic contact portions are located and then bent downward to form wiring portions; the elastic contact portions and the plate body portions form card slots; the elastic member has two elastic arms, and the lower ends of the two elastic arms are connected by an arc-shaped elastic portion; the two current-carrying members are arranged oppositely, and the wiring portions of the two current-carrying members abut against each other; the two elastic arms of the elastic member are respectively inserted into the card slots of the two current-carrying members.

[0008] Preferably, a locking piece is wound around the wiring portions of the two current-carrying members together.

[0009] Preferably, limiting platforms are formed by extending both sides of the lower part of the wiring portion, and the lower end of the locking piece abuts against the limiting platforms.

[0010] Preferably, a wiring hole is provided at the lower portion of the wiring portion.

[0011] Preferably, the elastic contact portion includes a guide plate and a lower plate body; the upper end of the guide plate is connected to the upper end of the plate body through a first arc-shaped connecting portion; the lower end of the guide plate is connected to the upper end of the lower plate body through a second arc-shaped connecting portion; the lower end of the guide plate is inclined in a direction away from the plate body, and the lower end of the lower plate body is inclined in a direction close to the plate body.

[0012] Preferably, the elastic arm includes an upper inclined plate and a lower inclined plate; the upper inclined plate and the lower inclined plate are connected by a third arc-shaped connecting portion; the upper ends of the two upper inclined plates on the elastic member are inclined in a direction away from each other to form a flared shape; the lower ends of the two lower inclined plates on the elastic member are inclined in a direction away from each other and are connected to the arc-shaped elastic portion; the third arc-shaped connecting portion of the elastic member is stuck at the inner concave surface position of the second arc-shaped connecting portion of the current-carrying member.

[0013] Preferably, the elastic member is formed by bending a stainless steel plate; and the current-carrying member is formed by punching and bending a T2 copper plate.

[0014] Preferably, the locking piece is made of T2 copper sheet.

[0015] On the other hand, the present invention further provides an electrical connector, comprising a base, wherein a mounting hole is provided on the base, and the female contact is mounted in the mounting hole.

[0016] Preferably, clamping blocks are extended on both sides of the plate body, and the clamping blocks are embedded in the inner wall of the mounting hole.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] (1) In the present invention, a female contact is formed by utilizing an elastic member and two current-carrying members, and a socket for accommodating the insertion of a male contact is formed between the elastic contact portions of the two current-carrying members. When the male contact is inserted, the two elastic arms of the elastic member are stretched apart, and the two elastic arms form an inward elastic force on the elastic contact portion, so that the two elastic contact portions can clamp the male contact. When the male contact is pulled out, the elastic contact portions of the two current-carrying members are brought closer to each other and reset under the action of the two elastic arms. Therefore, in the female contact provided by the present invention, since the elastic member is provided, the male contact can be clamped well.

[0019] (2) In the present invention, the elastic part and the current-carrying part adopt a split design. Two current-carrying parts and an elastic part are assembled into a female contact part. After being installed in the base, the wiring parts of the two current-carrying parts are wrapped and fixed with locking plates. The current-carrying part adopts T2 copper material with high conductivity to realize the current carrying or signal transmission of the connector. The elastic part adopts stainless steel material and has good elasticity, which can make the elastic contact parts of the two current-carrying parts clamp the male contact part well. The present invention realizes the independent functions of the current-carrying part and the elastic part of the connector, increases the design redundancy of the product, and improves the stability of the product.

[0020] (3) The elastic part and the current-carrying part in the present invention adopt a split design, which solves the problem of low reliability and low current carrying capacity of the female end contact of the connector being both an elastic part and a current-carrying part, increases the reliability of the female end contact, and ensures the spatial independence of the connector.

[0021] (4) In the present invention, the elastic member and the current-carrying member are designed as separate parts. The elastic member is formed by bending a stainless steel plate, while the current-carrying member is formed by punching and bending a T2 copper plate. Compared with traditional turning and forming processes, the female contact provided by this application is simple and fast to assemble, which improves the product assembly speed. The overall process and assembly are simple, making the product highly competitive in terms of cost. At the same time, it reduces costs and achieves the goal of low cost.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0031] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0032] Combine Figures 1 to 4As shown, on the one hand, this embodiment provides a female contact, including an elastic member 1 and two current-carrying members 2; the current-carrying member 2 includes a vertically arranged plate body 201; the upper end of the plate body 201 is bent downward to form an elastic contact portion 202; the lower end of the plate body 201 is bent horizontally toward the side where the elastic contact portion 202 is located and then bent downward to form a wiring portion 203; the elastic contact portion 202 and the plate body 201 form a card slot 204; the elastic member 1 has two elastic arms 101, and the lower ends of the two elastic arms 101 are connected by an arc-shaped elastic portion 102; the two current-carrying members 2 are arranged opposite to each other, and the wiring portions 203 of the two current-carrying members 2 are abutted together; the two elastic arms 101 of the elastic member 1 are respectively inserted into the card slots 204 of the two current-carrying members 2.

[0033] By adopting the above structure, a socket for accommodating the insertion of a male contact is formed between the elastic contact portions 202 of the two current-carrying members 2. When the male contact is inserted, the two elastic arms 101 of the elastic member 1 are stretched apart. The two elastic arms 101 exert an inward elastic force on the elastic contact portions 202, which can clamp the male contact. When the male contact is withdrawn, the elastic arms 101 act to bring the elastic contact portions 202 of the two current-carrying members 2 closer together and reset them. Therefore, in this female contact, the provision of the elastic member 2 can effectively clamp the male contact.

[0034] Combine Figure 2 As shown, a locking piece 3 is wound around the connection parts 203 of the two current-carrying components 2. By using the locking piece 3, the two connection parts 203 are tied together to form an integral terminal structure.

[0035] Combine Figure 3 As shown, both sides of the lower portion of the connection portion 203 extend to form a limiting platform 203a, and the lower end of the locking piece 3 abuts against the limiting platform 203a. By utilizing the limiting platform 203a to limit the locking piece 3, the locking piece 3 is effectively prevented from sliding.

[0036] Combine Figure 3 As shown, a wiring hole 203b is provided at the lower portion of the wiring portion 203. When the two wiring portions 203 are put together, the axes of the wiring holes 203b on the two wiring portions 203 coincide. The purpose of providing the wiring hole 203b is to facilitate wiring.

[0037] Combine Figure 2 and Figure 3As shown, the elastic contact portion 202 includes a guide plate 202a and a lower plate body 202c; the upper end of the guide plate 202a is connected to the upper end of the plate body portion 201 through a first arc-shaped connecting portion 205; the lower end of the guide plate 202a is connected to the upper end of the lower plate body 202c through a second arc-shaped connecting portion 202b; the lower end of the guide plate 202a is inclined away from the plate body portion 201, and the lower end of the lower plate body 202c is inclined toward the plate body portion 201. By adopting the above structure, the two guide plates 202a on the entire female terminal contact jointly form a socket in the shape of a "V"-shaped flared opening. Therefore, the inclined guide plate 202a plays a guiding role to facilitate the insertion of the male terminal contact. In addition, since the lower end of the lower plate body 202c is inclined toward the plate body portion 201, when the male terminal contact is pulled out, interference between the lower plate body 202c and the male terminal contact can be avoided.

[0038] Combined with Figure 2 as shown in Figure 4 As shown, the elastic arm 101 includes an upper inclined plate 101a and a lower inclined plate 101c; the upper inclined plate 101a and the lower inclined plate 101c are connected through a third arc-shaped connecting portion 101b; the upper ends of the two upper inclined plates 101a on the elastic member 1 are inclined away from each other to form a flared opening; the lower ends of the two lower inclined plates 101c on the elastic member 1 are inclined away from each other and are connected to the arc-shaped elastic portion 102; the third arc-shaped connecting portion 101b of the elastic member 1 is stuck at the concave surface position of the second arc-shaped connecting portion 202b of the current-carrying member 1, which can enable the two elastic arms 101 to be better stuck in the card slots 204 of the two current-carrying members 2.

[0039] In this embodiment, the elastic member 1 is formed by bending a stainless steel plate; the current-carrying member 1 is formed by punching and bending a T2 copper plate. The material of the locking piece 3 is a T2 copper sheet.

[0040] Combined with Figure 5 As shown, this embodiment further provides an electrical connector, including a base 4, and an installation hole 4a is provided on the base 4. The above-mentioned female terminal contact is installed in the installation hole 4a for transmitting electrical signals.

[0041] Combined with Figure 3 As shown, on both sides of the plate body portion 201, a clamping block 201a extends and is embedded in the inner wall of the installation hole 4a. By using the clamping block 201a, it can be ensured that the female terminal contact is firmly installed in the installation hole 4a of the base 4 and prevent it from falling off.

[0042] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
