Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a socket structure for a connection terminal and a connector. Background Technology
[0002] The socket of the connector plays a crucial role in the current conduction process. Conventional sockets have a spring inside, and the contact effect between the spring and the inner wall of the socket directly affects the current carrying capacity. When the pin is inserted into the spring, the tension of the spring makes it abut against the inner wall of the socket. However, if this contact effect is poor, it is difficult to further improve the current carrying capacity of the connector. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a socket structure for connecting terminals.
[0004] The present invention discloses a socket structure for a connecting terminal, comprising: a sleeve, a spring, and a pressure sleeve. The sleeve has a receiving hole, the spring is disposed in the receiving hole, the pressure sleeve is located at one end of the sleeve and is engaged with one end of the spring, and the pressure sleeve and the spring are interference-fitted. The pressure sleeve has a second guide hole. A pin passes through the second guide hole and enters the receiving hole, and abuts against the spring.
[0005] According to one embodiment of the present invention, the pressure sleeve includes a support ring and a pressure post. The support ring is disposed at the end of the sleeve, the pressure post is connected to the support ring, the pressure post is located in the receiving hole, and the pressure post is interference-fitted with the spring.

[0008] According to one embodiment of the present invention, the end of the sleeve away from the pressure sleeve is provided with a stepped surface, the stepped surface extends toward the center of the receiving hole, and the end of the spring away from the pressure sleeve abuts against the stepped surface.
[0009] According to one embodiment of the present invention, the spring includes a first fixing ring, a second fixing ring, and a plurality of elastic strips that together form a first guide hole. The two ends of the plurality of elastic strips are respectively connected to the first fixing ring and the second fixing ring. The first guide hole and the second guide hole are in communication.

[0012] According to one embodiment of the present invention, the reed is made of a material with high conductivity and high yield strength.
[0013] The present invention discloses a connector including the aforementioned socket structure of the connecting terminal.
[0014] The beneficial effect of this utility model is that, through the interference fit between the pressure sleeve and the spring, the spring and the inner wall of the receiving hole are more closely fitted, increasing the contact area and positive force between them.

[0025] Example 1
[0026] like Figures 1-3 As shown, Figure 1 A three-dimensional structural diagram of the socket structure for connecting terminals; Figure 2 A split view of the socket structure for connecting terminals; Figure 3 This is a cross-sectional schematic diagram of the socket structure of the connecting terminal. The socket structure of the connecting terminal includes a sleeve 1, a spring 2, and a pressure sleeve 3. The spring 2 is disposed inside the sleeve 1, and the pressure sleeve 3 is located at one end of the sleeve 1 and abuts against the spring 2, thereby pressing the spring 2 tightly against the sleeve 1 through the pressure sleeve 3.
[0027] The sleeve 1 has a receiving hole 11, which is opened along the axial direction of the sleeve 1. The spring 2 is disposed in the receiving hole 11, and the spring 2 can abut against the inner wall surface of the receiving hole 11 by its own tension. The pressure sleeve 3 extends into the receiving hole 11 and presses the spring 2 against the inner wall surface of the receiving hole 11. Furthermore, the sleeve 1 also has a stepped surface 12, which is located at the end of the sleeve 1 away from the pressure sleeve 3. The stepped surface 12 extends towards the center of the receiving hole 11, that is, the stepped surface 12 protrudes towards the center of the receiving hole 11. The end of the spring 2 away from the pressure sleeve 3 abuts against the stepped surface 12. The stepped surface 12 limits the spring 2 to prevent the spring 2 from falling out of the receiving hole 11.
[0028] The spring 2 includes a first fixing ring 21, a second fixing ring 22, and multiple elastic strips 23. The first fixing ring 21 is located at the end of the sleeve 1 away from the stepped surface 12, the second fixing ring 22 abuts against the stepped surface 12, and the multiple elastic strips 23 are spaced apart between the first fixing ring 21 and the second fixing ring 22, i.e., the two ends of an elastic strip 23 are respectively connected to the first fixing ring 21 and the second fixing ring 22. Simultaneously, the first fixing ring 21, the second fixing ring 22, and the multiple elastic strips 23 together form a first guide hole 20. The pressure sleeve 3 extends into the first guide hole 20 and presses the first fixing ring 21 tightly against the inner wall of the receiving hole 11. In use, the pin is inserted into the first guide hole 20, and all the multiple elastic strips 23 abut against the pin.
[0029] Specifically, multiple elastic strips 23 are obliquely disposed between the first fixing ring 21 and the second fixing ring 22. In this embodiment, the spring 2 is a one-piece structure, meaning that the spring 2 can be manufactured by a stamping process and then rolled into a circle. The spring 2 is made of a material with high conductivity and high yield strength, for example, the same material used in existing crown springs.
[0030] The pressure sleeve 3 includes a support ring 31 and a pressure post 32. The support ring 31 is located at the end of the sleeve 1 away from the stepped surface 12. The pressure post 32 is connected to the support ring 31 and is located inside the first guide hole 20. The pressure post 32 and the first fixing ring 21 are interference-fitted, meaning that the outer wall of the pressure post 32 presses against the wall of the first fixing ring 21 facing the first guide hole 20, so that the other wall of the first fixing ring 21 can fit more tightly against the inner wall of the receiving hole 11. Furthermore, a second guide hole 30 is provided along the axial direction of the pressure post 32. The second guide hole 30 communicates with the first guide hole 20, and the pin can be inserted into the first guide hole 20 after passing through the second guide hole 30.
[0031] In this embodiment, the support ring 31 and the pressure column 32 are an integral structure to facilitate manufacturing. The support ring 31 and the pressure column 32 are arranged perpendicularly to improve the connection stability between the sleeve 1, the spring 2, and the pressure sleeve 3.
[0032] In summary, the interference fit between the pressure sleeve 3 and the spring 2 makes the spring 2 fit more tightly against the inner wall of the receiving hole 11, increasing the contact area and positive force between them. During the insertion of the pin, the spring 2 is further pushed against the inner wall of the receiving hole 11, ultimately improving the overall current carrying capacity.
