Embodiment 1

[0042] An electrical contact piece with elastic contact elements doubles the number of contact points, and when the cross-sectional area of ​​the linear conductor 3 remains unchanged, the current-carrying capacity is doubled; when the current-carrying capacity remains unchanged In the case of , the cross-sectional area of ​​the linear conductor becomes smaller, which saves the cost, and can also make the space occupied by the electrical contact smaller.

[0043] like figure 1 Shown is a schematic diagram of the overall structure of an electrical contact with elastic contact elements, including an elastic contact element 1, the elastic contact element 1 includes a plurality of unit helical rings 2, and the plurality of unit helical rings 2 are along a trajectory line connected end to end in sequence; the unit spiral ring 2 is surrounded by a linear conductor 3, and the cross-sectional shape of the elastic contact element 1 is a double ellipse structure; wherein, the cross-secti...

Embodiment 2

[0078] In order to improve the stability of the electrical contact piece with the elastic contact element of the present invention and prevent the electrical conductivity from being reduced due to deformation, in this embodiment, the difference from Embodiment 1 is that the elastic contact element 1 also includes a support 4. The support member 4 is disposed inside the elastic contact element 1 , further, the outer wall of the support member 4 is partially or completely attached to the inner wall of the elastic contact element 1 to support the elastic contact element 1 .

[0079] Among them, as a preferred embodiment 2-1 of the present invention, such as Figure 15 As shown, the support member 4 is in contact with the inner wall of the elastic contact element 1, wherein the support member 4 is used to support the first fixed contact portion and the second fixed contact portion 224 of the elastic contact element 1. In specific applications, the support member 4 makes The first ...

Embodiment 3

[0084] When the electrical contact works under high current or in the working state for a long time, a lot of heat will be generated, which will gradually increase the temperature inside the electrical contact. However, high temperature will have a great impact on the electrical conductivity of the electrical contact. Therefore, there is a need for an electrical contact with a built-in liquid cooling medium and an elastic contact element, which can continuously take away the internal heat of the electrical contact during the working process of the electrical contact, so as to ensure that the temperature inside the electrical contact is constant , so as to ensure good electrical conductivity of the electrical contacts.

[0085] The difference between this embodiment and Embodiment 1 is that the electrical contact piece with a built-in liquid cooling medium and an elastic contact element includes an elastic contact element 1 and a liquid cooling conduit 5; the liquid cooling cond...

Abstract

An electrical connector with a socket contact, comprising a socket contact, the socket contact includes a socket body, at least one elastic contact element, the inner wall of the socket body is provided with a socket for accommodating the elastic contact element The accommodating groove; the elastic contact element includes a plurality of unit spiral rings, and the plurality of unit spiral rings are connected end-to-end along a trajectory line; the unit spiral ring is formed by a linear conductor, and the cross-sectional shape of the elastic contact element is A double ellipse structure; wherein, the shape of the trajectory line is a spiral. The invention provides an electrical connector with socket contacts, which doubles the number of contact points, and doubles the current-carrying capacity when the cross-sectional area of ​​the linear conductor remains unchanged; Under the condition that the current flow capacity remains unchanged, the cross-sectional area of ​​the linear conductor becomes smaller, thereby saving costs.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an electrical connector with socket contacts. Background technique [0002] In electrical connectors, the contact area of ​​the electrical connection is an important indicator to measure the reliability of the connection, especially for electrical connectors working under high current. In the prior art, single-wire helical springs are generally used to contact electrical connections with multiple contacts. The published patents that have been retrieved include: the patent application document with the publication number CN102427180A discloses a spring contact, socket and socket system, wherein, The spring contact finger includes a spring wire, and the spring wire is helically wound along an oblique elliptical trajectory to form a unit ring, and the unit ring is helically wound bidirectionally along the axis to form an oblique elliptical spring contact finger, so as ...
