Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a multi-point contact connector female terminal. Background Technology
[0002] Traditional connector female terminals typically have only two contact points, a design that presents limitations in terms of connection reliability and contact electrical performance. This is particularly true in applications requiring high reliability and low insertion / extraction force, where traditional designs struggle to meet the demands. Even with current multi-point contact terminal structures, contact with the male terminal is usually achieved at the same location, resulting in a single contact position and insufficient stability, thus requiring further improvement. Utility Model Content
[0003] The purpose of this invention is to provide a multi-point contact connector female terminal to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A multi-point contact connector female terminal includes a female terminal body; the front left and right sides of the female terminal body are provided with symmetrically arranged left contact springs and right contact springs; the front of the female terminal body is also provided with a surrounding body corresponding to the front side of the left contact springs and right contact springs; the rear lower part of the surrounding body is integrally fixedly connected to the front lower part of the female terminal body through a connecting piece; the connecting piece is formed with an upwardly curved lower contact portion; an upper contact spring is provided on the rear upper part of the surrounding body; the upper contact spring is arranged vertically opposite to the lower contact portion and is located in front of the left contact springs and right contact springs.
[0006] In a further description of this utility model, the upper contact spring, the left contact spring, and the right contact spring are all springs that are bent inward.
[0007] In a further description of this utility model, the distance between the upper contact spring and the lower contact portion is less than the thickness of the male terminal; the distance between the left contact spring and the right contact spring is less than the width of the male terminal.
[0008] In a further description of this utility model, a wire clamp is connected to the rear end of the female terminal body.
[0009] The beneficial effects of this utility model are as follows:
[0010] The male terminal is inserted into the female terminal of the connector in this design. The enclosure initially positions the male terminal. The upper contact spring and the lower contact part abut against the upper and lower sides of the male terminal, while the left contact spring and the right contact spring abut against the left and right sides of the male terminal. The male terminal is fixed by a four-point contact method, and different parts of the male terminal are abutted, which can effectively reduce the contact resistance and has high vibration resistance, good electrical performance, and high stability. Moreover, the upper contact spring, left contact spring and right contact spring in this design are all elastic contacts, which greatly reduces the friction when mating with the male terminal and effectively meets the low insertion and extraction force requirements of the connector. Attached Figure Description
[0011] Figure 1 This is an overall structural diagram of the present invention;
[0012] Figure 2 This is a schematic diagram of the structure of this utility model connected to the male terminal. Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings:
[0014] like Figure 1-2 As shown, a multi-point contact connector female terminal includes a female terminal body 1; the front left and right sides of the female terminal body 1 are provided with symmetrically arranged left contact springs 2 and right contact springs 3; the front of the female terminal body 1 is also provided with a surrounding body 4 corresponding to the front side of the left contact springs 2 and right contact springs 3; the rear lower part of the surrounding body 4 is integrally fixedly connected to the front lower part of the female terminal body 1 by a connecting piece 5; the connecting piece 5 is formed with an upwardly curved lower contact portion 51; an upper contact spring 41 is provided on the rear upper part of the surrounding body 4; the upper contact spring 41 and the lower contact portion 51 are arranged vertically opposite each other and located in front of the left contact springs 2 and right contact springs 3; in use, the male terminal 10 is connected... The male terminal 100 is inserted into the female terminal of the connector in this design. The enclosure 4 initially positions the male terminal 100. The upper contact spring 41 and the lower contact part 51 abut against the upper and lower sides of the male terminal 100. The left contact spring 2 and the right contact spring 3 abut against the left and right sides of the male terminal 100. The male terminal 100 is fixed by a four-point contact method, and different parts of the male terminal 100 are abutted, which can effectively reduce the contact resistance and has high vibration resistance, good electrical performance, and high stability. Moreover, the upper contact spring 41, left contact spring 2 and right contact spring 3 in this design are all elastic contacts, which greatly reduces the friction when mating with the male terminal 100 and effectively meets the low insertion and extraction force requirements of the connector.
[0015] The upper contact spring 41, the left contact spring 2, and the right contact spring 3 are all springs that are bent inward to form a V-shaped contact end with an arc, which improves the smoothness of the male terminal 100 when it is inserted and can also increase the clamping force.
[0016] The distance W1 between the upper contact spring 41 and the lower contact portion 51 is less than the thickness T1 of the male terminal 100; the distance W2 between the left contact spring 2 and the right contact spring 3 is less than the width W3 of the male terminal 100. This arrangement can increase the clamping force on the male terminal 100, thereby improving stability.
[0017] The rear end of the female terminal body 1 is connected to a wire clamp 6, which is used to clamp and fix the wire.
[0018] The above description does not limit the technical scope of this invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this invention shall still fall within the scope of the technical solution of this invention.
