Description

Technical Field

[0001] The utility model relates to the field of connector design, and particularly relates to a copper core structure of a connector. Background Technique

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device that connects two active devices and transmits current or signals. The male end and the female end can transmit information or current after contact, and it is also called a connector.

[0003] At present, there is generally no buffer limit structure after the connector is inserted into the socket. For example, in the prior art (Publication No.: CN219247102U, Publication Date: June 23, 2023), a connector with a short-circuit function is disclosed. When it is electrically connected, the conductive component clamps the electrical pin through the clamping end. Since the clamping end is not equipped with a limit structure, when the connector encounters external force oscillation, the connector is likely to automatically separate from the socket, resulting in a disconnection of the connection and an unstable electrical connection.

[0004] To solve this technical problem, in the prior art (Publication No.: CN220272790U, Publication Date: December 29, 2023), a power connector is disclosed. During its use, when the connection pin is inserted into the conductive copper sheet, the elastic arm on the conductive copper sheet can clamp the barb of the connection pin, and it will not disconnect when pulled by an external force, and stable connection of each connection pin can be achieved.

[0005] However, this solution requires structures such as a connector housing, an inclined plane, a spring, etc. to be able to be used normally, and its design is relatively complex. And for existing connectors, it is only necessary to overcome the defect of unstable electrical connection caused by oscillation. Therefore, it is necessary to design a copper core of a connector with a buffer limit structure to solve this technical problem. Content of the Utility Model

[0006] The utility model provides a technical solution that can solve the above problems to overcome the above deficiencies.

[0007] A copper core structure of a connector includes a conductive member. The right end of the conductive member is bent to form a plug-in end, and the cross-section of the plug-in end is bent into a "mouth" shape. Elastic arms are formed on both the front and rear sides of the plug-in end. Elastic arms are formed on both the left and right sides of the slot, and the middle of the elastic arm is bent inward. The two elastic arms in the same slot are separated from each other left and right; a conductive pin is inserted and fitted in the plug-in end. Two limiting slots are formed on both the front and rear sides of the conductive pin, and the elastic arms are respectively pressed into the limiting slots; an arc chamfer is formed between the two limiting slots on the front or rear side of the conductive pin. After the conductive pin is inserted into the plug-in end, the arc chamfer is located at the separation gap between the two elastic arms in the slot; the left end of the conductive member is formed with a wire pressing end, and a wire is electrically connected and installed in the wire pressing end.

[0008] Further: The cross-section of the wire pressing end is bent into a "U" shape, and at least two pairs of pressing edges are formed on the side of the wire pressing end. The wire is locked in the "U" shape of the wire pressing end through at least two pairs of pressing edges.

[0009] Further: An exposed end is provided at one end of the wire close to the conductive member. There are three pairs of pressing edges. Two pairs of pressing edges are bent inward to lock the exposed end of the wire in the "U" shape of the wire pressing end, and the other pair of pressing edges are bent inward to lock the wire in the "U" shape of the wire pressing end.

[0010] Further: A convex edge is formed at the bottom edge on the right side of the plug-in end. A pin base is fixedly installed at the right end of the conductive pin, and a U-shaped gasket is fixedly installed on the left side of the pin base. The convex edge is inserted into the opening of the U-shaped gasket with a clearance fit.

[0011] Further: A stepped structure is formed between the pin base and the conductive pin, and a direction pointer is formed on the upper side of the pin base.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. The plug-in end is bent into a "mouth" shape, which can effectively enhance the overall strength of the plug-in end and ensure that it is not easily damaged after the conductive pin is inserted and unplugged multiple times;

[0014] 2. Two elastic arms are provided in the slots on both sides of the plug-in end, and these two elastic arms are separated left and right, and can form a limiting and buffering structure with the limiting slots of the conductive pin;

[0015] 2.1 The elasticity of the elastic arm can effectively press the conductive pin, thereby achieving the effect of anti-vibration;

[0016] 2.2 The arc chamfer between the two limiting slots is located at the separation gap between the two elastic arms, so a limiting structure can be formed;

[0017] When the utility model oscillates, it will not easily shift, thereby realizing anti-limiting buffering. It does not need to be equipped with a self-locking mechanism with a complex structure for use, and the production cost is low.

[0029] As Figures 1-3 shown, a copper core structure of a connector of the present utility model includes a conductive member 1. A plug-in end 2 is bent and formed at the right end of the conductive member 1. The cross-section of the plug-in end 2 is bent into a "mouth" type structure. Slots 3 are formed on both the front and rear sides of the plug-in end 2. Elastic arms 4 are formed on both the left and right sides inside the slots 3. The middle of the elastic arms 4 is bent inward. The two elastic arms 4 in the same slot 3 are separated from each other left and right; A conductive pin 5 is inserted and fitted inside the plug-in end 2. Two limiting slots 6 are formed on both the front and rear sides of the conductive pin 5. The elastic arms 4 are respectively pressed inside the limiting slots 6; An arc chamfer 15 is formed between the two limiting slots 6 on the front or rear side of the conductive pin 5. After the conductive pin 5 is inserted into the plug-in end 2, the arc chamfer 15 is located at the separation gap between the two elastic arms 4 inside the slot 3; A wire pressing end 7 is formed at the left end of the conductive member 1. A wire 8 is electrically connected and installed inside the wire pressing end 7;

[0030] The principle is as follows: The insertion end 2 is bent into a "mouth" - shaped structure, which can effectively enhance the overall strength of the insertion end 2, ensuring that it is not easily damaged after the conductive pin 5 is inserted and unplugged multiple times. In addition, two elastic arms 4 are provided in the slots 3 on both sides of the insertion end 2, and these two elastic arms 4 are separated left and right, and can form a limit buffer structure with the limit slots 6 of the conductive pin 5. The elasticity of the elastic arms 4 can effectively press the conductive pin 5, thereby achieving the effect of anti - vibration. The arc chamfer 15 between the two limit slots 6 is located at the separation gap between the two elastic arms 4, so it can form a limit structure and will not easily shift during vibration, thus achieving anti - limit buffering. There is no need to use a complex self - locking mechanism, and the production cost is low.

[0031] Furthermore: The cross - section of the wire - pressing end 7 is bent into a "U" - shaped structure, and at least two pairs of pressing edges 9 are formed on the side of the wire - pressing end 7. The wire 8 is locked in the "U" - shaped structure of the wire - pressing end 7 through at least two pairs of pressing edges 9; The wire 8 can be fixed in the wire - pressing end 7 by bending the pressing edges 9, realizing rapid assembly.

[0032] Furthermore: An exposed end 10 is provided at one end of the wire 8 close to the conductive part 1. There are three pairs of pressing edges 9. Two of the pairs of pressing edges 9 are bent inward to lock the exposed end 10 of the wire 8 in the "U" - shaped structure of the wire - pressing end 7, and the other pair of pressing edges 9 is bent inward to lock the wire 8 in the "U" - shaped structure of the wire - pressing end 7; The three pairs of pressing edges 9 can be bent to fasten the wire 8. The three pairs of pressing edges 9 can respectively press the electrical part and the exposed end 10, realizing rapid assembly and ensuring stable electrical connection at the same time.

[0033] Furthermore: A raised edge 11 is formed at the bottom edge on the right side of the insertion end 2. A pin base 12 is fixedly installed at the right end of the conductive pin 5, and a U - shaped gasket 13 is fixedly installed on the left side of the pin base 12. The raised edge 11 is inserted into the opening of the U - shaped gasket 13 with a clearance fit; The setting of the U - shaped gasket 13 can play an additional buffering effect. At the same time, the cooperation between the raised edge 11 and the opening of the U - shaped gasket 13 can effectively prevent the conductive pin 5 from being inserted in the wrong direction, thereby ensuring stable electrical connection and facilitating actual use.

[0034] Furthermore: A stepped structure is formed between the pin base 12 and the conductive pin 5, and a direction pointer 14 is formed on the upper side of the pin base 12; It can cooperate with the raised edge 11 and the U - shaped gasket 13 to achieve the insertion action, thereby effectively preventing the conductive pin 5 from being inserted in the wrong direction.

[0035] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present utility model. Any simple modification, equivalent change, and modification made to the above - mentioned embodiments based on the technical essence of the present utility model all fall within the protection scope of the technical solution of the present utility model.
