Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a fixing structure for an electrical connector. Background Technology

[0002] Existing electrical connectors use a retaining part that interferes with the inner wall of the terminal receiving hole. While this prevents the conductive terminals from moving up and down, the increasing number of conductive terminals leads to excessive interference between them and the insulating body. This causes the plastic insulating body to warp and deform, ultimately affecting the product's functionality. Furthermore, the significant interference between the conductive terminals and the insulating body necessitates high precision during pin insertion, potentially resulting in poor contact. Therefore, it is necessary to ensure that the pins have a stable structure to reduce bending and deformation during insertion and removal. Utility Model Content

[0003] The purpose of this invention is to provide a fixing structure for an electrical connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixing structure for an electrical connector, including a plug and a socket. The plug is further provided with pins inside, and a first fixing cover is provided to fit over the pins and connect to the plug to fix the pins. The socket is further provided with a second fixing cover, and the second fixing cover is provided with a through hole. The pins pass through the through hole and connect to a contact provided in the socket.

[0005] As a preferred technical solution of this utility model: the contact includes a conductive part, and the conductive part surrounds the pin.

[0006] As a preferred technical solution of this utility model: the contact element further includes a housing, and the conductive part is caused to converge toward its center through the housing.

[0007] As a preferred technical solution of this utility model: one end of the pin is also provided with a round hole, and the center of the inner bottom surface of the conductive part is also provided with a pin that is inserted into the round hole.

[0008] As a preferred technical solution of this utility model, the conductive part is a crown spring.

[0009] As a preferred technical solution of this utility model: the first fixing cover and the second fixing cover have the same structure, and the interior of the second fixing cover is a hollow structure.

[0010] As a preferred technical solution of this utility model: a fan-shaped slot is provided on the outside of the through hole, and the number of the fan-shaped slots is multiple, and they are arranged in a circumferential array on the outside of the through hole.

[0011] The beneficial effects of this utility model by adopting the above technical solution are as follows: Since the first fixing cover fixes the pin inside the plug, and the second fixing cover contacts the pin in advance during the insertion process and guides the pin into the socket; the first fixing cover shortens the exposed length of the pin, improves the structural strength of the pin, and thus reduces the bending of the pin during insertion and removal. At the same time, the second fixing cover contacts the pin in advance, guides the pin to move, and fixes the pin during the movement, thus further preventing the pin from deforming during insertion.

[0019] Please see Figure 1-5The present invention provides an embodiment of a fixing structure for an electrical connector, comprising a plug 1 and a socket 4. The plug 1 is further provided with pins 3 inside, and a first fixing cover 2 is provided to fit the pins 3 and connect to the plug 1 to fix the pins 3. The socket 4 is further provided with a second fixing cover 5, and the second fixing cover 5 is provided with a through hole 6. The pins 3 pass through the through hole 6 and connect to a contact 7 provided in the socket 4.

[0020] In summary, since the first fixing cover 2 fixes the pin 3 inside the plug 1, and the second fixing cover 5 contacts the pin 3 in advance during the insertion process and guides the pin 3 into the socket 4, the first fixing cover 2 shortens the exposed length of the pin 3, improves the structural strength of the pin 3, and reduces the possibility of the pin 3 bending due to obstruction during insertion and removal. At the same time, the second fixing cover 5 contacts the pin 3 in advance, guides the pin 3 to move, and fixes the pin 3 during the movement, thus further preventing the pin 3 from deforming during insertion.

[0021] Furthermore, since the contact 7 includes a conductive part 9 and surrounds the pin 3 through the conductive part 9, a stable and reliable connection can be achieved between the pin 3 and the conductive part 9.

[0022] Furthermore, the contact 7 also includes a housing 11, which causes the conductive part 9 to converge toward its center, thus allowing the conductive part 9 to be tightly held against the outside of the pin 3.

[0023] In summary, by having the conductive part 9 encircle the outside of the pin 3, and then using the outer shell 11 to make the conductive part 9 converge towards the center of the outer shell 11, the stability of the conductive part 9 after connecting with the pin 3 is improved, thus avoiding poor contact due to shaking during the connection process; wherein, the conductive part 9 is a crown spring.

[0024] Based on the above solution, since one end of the pin 3 is also provided with a round hole 8, and the center of the inner bottom surface of the conductive part 9 is also provided with a pin 10 inserted into the round hole 8, the connection between the pin 3 and the contact 7 is more stable and reliable under the combined action of the first fixing cover 2, the second fixing cover 5 and the pin 10.

[0025] Furthermore, since the first fixing cover 2 and the second fixing cover 5 have the same structure, and the interior of the second fixing cover 5 is a hollow structure, it can reduce the weight of the socket 4 and the plug 1, reduce material consumption, and facilitate heat dissipation.

[0026] Furthermore, since the outside of the through hole 6 is also provided with a fan-shaped slot 12, and there are multiple fan-shaped slots 12 arranged in a circumferential array on the outside of the through hole 6, when the plug 1 is pulled out, the heat remaining in the socket 4 and the plug 1 can be quickly released to the outside through the fan-shaped slots 12.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
