Description

Technical Field

[0001] This utility model relates to the field of connector terminal technology, specifically to a main and auxiliary spring contact terminal structure. Background Technology

[0002] The function of a connector is to achieve reliable connection and signal transmission between different systems, components or devices. The pins are inserted into the connector and can act as conductive contacts to achieve stable transmission of current or signals. The connector is inserted with pins to make conductive connections. In the existing technology, if there is a large gap between the connector and the pins, the resistance between the two is easy to increase, which will affect the current transmission. Utility Model Content Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that if there is a large gap between the connector and the pin, the resistance between the two will easily increase, thus affecting the current transmission, thereby providing a main and auxiliary spring terminal structure that can ensure a tight connection between the connector and the pin.

[0003] Therefore, this utility model provides a main and auxiliary spring terminal structure, including a body, in which a slot for inserting an external pin is provided, a main spring contacting the pin and an auxiliary spring contact disposed above the main spring contact and applying an elastic force to the main spring contact are provided in the slot, and a contact point for contacting the pin is provided on the main spring contact.

[0004] Furthermore, the main body is provided with a bending portion, and the main body is provided with a limiting block for preventing overpressure on the bending portion.

[0005] Furthermore: one side of the main spring is integrally formed with the body, and the other side is inserted into the side wall of the body; one end of the auxiliary spring is integrally formed with the body, and the other end is inserted into the side wall of the body; the limiting block is disposed on the auxiliary spring.

[0006] Furthermore, the main spring sheet has a reinforcing bubble point on the side facing away from the contact point.

[0007] Furthermore: the main spring includes a first positioning end connected to the body and a first contact end in contact with the insert pin. The first positioning end and the first contact end are integrally formed. A first positioning block is provided on the first positioning end and inserted into the side wall of the body. A first positioning groove adapted to the first positioning block is provided on the side wall of the body. The reinforcing bubble is provided at the connection between the first positioning end and the first contact end.

[0008] Furthermore: the auxiliary spring includes a second positioning end connected to the main body and a second abutting end abutting above the first contact end. The second positioning end and the second abutting end are integrally formed. A second positioning block is provided on the second positioning end within the side wall of the main body. A second positioning groove adapted to the second positioning block is provided on the side wall of the main body.

[0009] Furthermore, the second abutment end is configured with an inverted "V" shape.

[0010] The technical solution of this utility model has the following advantages: 1. The present invention provides a main and auxiliary spring contact terminal structure, wherein a slot is provided in the main body, and a pin is inserted into the slot to contact the main spring contact. In order to increase the contact force between the main spring contact and the pin and avoid a large gap between the two, thereby increasing the resistance, an auxiliary spring contact is added above the main spring contact. The auxiliary spring contact applies an elastic force to the main spring contact, which deforms towards the side closer to the pin, thereby effectively ensuring that the contacts on the main spring contact can make tight contact with the pin and ensuring the stability of the contact between the two.

[0011] 2. The present invention provides a main and auxiliary spring contact terminal structure. In order to prevent the entire barb from failing due to excessive downward pressure of the bent part, a limiting block is provided on the main body. When the bent part is pressed down until its lower end face abuts against the upper end face of the limiting block, the bent part can no longer deform downward. This can effectively prevent the long-term plastic deformation caused by excessive downward pressure of the bent part from eventually leading to the failure of the entire barb.

[0018] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example This embodiment provides a main and auxiliary spring terminal structure, including a body 1. The body 1 is provided with a slot 12 for inserting an external pin. The slot 12 is provided with a main spring 3 that contacts the pin and an auxiliary spring 4 that is disposed above the main spring 3 and applies an elastic force to the main spring 3. The main spring 3 is provided with a contact point 5 that contacts the pin.

[0020] The specific improvements mentioned above are as follows: Figures 1-7As shown, the entire terminal is sleeved inside the sheath 10. A slot 12 is provided inside the body 1. The pin is inserted into the slot 12 and contacts the main spring 3. In order to increase the contact force between the main spring 3 and the pin and avoid a large gap between them, which would increase the resistance, an auxiliary spring 4 is added above the main spring 3. The auxiliary spring 4 applies an elastic force to the main spring 3, which deforms towards the side closer to the pin. This can effectively ensure that the contact 5 on the main spring 3 can make tight contact with the pin and ensure the stability of the contact between the two.

[0021] Based on the above embodiments: the main body is provided with a bending portion 24, and the main body 1 is provided with a limiting block 11 for preventing overpressure of the bending portion 24.

[0022] The specific improvements mentioned above are as follows: Figure 6 As shown, the bending part 24 is U-shaped. To prevent the bending part 24 from being pressed down too much and causing the entire barb 2 to fail, a limiting block 11 is provided on the body 1. When the bending part 24 is pressed down until its lower end face abuts against the upper end face of the limiting block 11, the bending part 24 can no longer deform downwards. This can effectively prevent the long-term increase in plastic deformation caused by the excessive pressing of the bending part 24 from ultimately causing the entire barb 2 to fail.

[0023] Based on the above embodiments: one side of the main spring plate 3 is integrally formed with the body 1, and the other side is inserted into the side wall of the body 1; one end of the auxiliary spring plate 4 is integrally formed with the body 1, and the other end is inserted into the side wall of the body 1; the limiting block 11 is disposed on the auxiliary spring plate 4.

[0024] The specific improvements mentioned above are as follows: Figure 3 As shown, the main spring 3 is formed by processing the material extending from the body 1. The side of the main spring 3 that is opposite to the side connected to the body 1 is inserted into the side wall of the body 1 to ensure the fixing force of the main spring 3. Similarly, the secondary spring 4 that is opposite to the side connected to the body 1 is inserted into the side wall of the body 1 to ensure the fixing force of the secondary spring 4.

[0025] Based on the above embodiments: the main spring sheet 3 is provided with a reinforcing bubble point 6 on the side opposite to the contact point 5.

[0026] The specific improvements mentioned above are as follows: Figure 6 As shown, by strengthening the setting of bubble point 6, the hardness of the root of the main spring piece 3 can be increased, and the degree of deformation of the main spring piece 3 during use can be reduced.

[0027] Based on the above embodiments: the main spring 3 includes a first positioning end 31 connected to the body 1 and a first contact end 32 in contact with the insert pin. The first positioning end 31 and the first contact end 32 are integrally formed. A first positioning block 33 inserted into the side wall of the body 1 is provided on the first positioning end 31. A first positioning groove 34 adapted to the first positioning block 33 is provided on the side wall of the body 1. The reinforcing bubble 6 is provided at the connection between the first positioning end 31 and the first contact end 32.

[0028] Based on the above embodiments: such as Figure 5 and Figure 6 As shown, the secondary spring 4 includes a second positioning end 41 connected to the body 1 and a second abutting end 42 abutting above the first contact end 32. The second positioning end 41 and the second abutting end 42 are integrally formed. A second positioning block 43 is provided on the second positioning end 41 within the side wall of the body 1. A second positioning groove 44 adapted to the second positioning block 43 is provided on the side wall of the body 1.

[0029] Based on the above embodiments: the second abutment end 42 is configured with an inverted "V" shape.

[0030] The specific improvements mentioned above are as follows: Figure 6 As shown, the main spring 3 is formed by combining the first positioning end 31 and the first contact end 32. The reinforcing bubble 6 is set at the connection between the first positioning end 31 and the first contact end 32, which can reinforce the position of the connection and prevent the first contact end 32 from failing. The secondary spring 4 includes a second positioning end 41 and a second abutting end 42. The second abutting end 42 forms an inverted "V" shaped structure, which can effectively apply a downward elastic force to the first contact end 32, thereby ensuring that the pin can be tightly connected with the first contact end 32.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
