Embodiment 1

[0043] An electrical contact with elastic contact elements doubles the number of contact points. 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 this case, the cross-sectional area of ​​the linear conductor becomes smaller, which saves the cost and also reduces the space occupied by the electrical contact.

[0044] like figure 1 Shown is a schematic diagram of the overall structure of an electrical contact with an elastic contact element, 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 track line 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 elliptical structure; wherein, the cross-sectional shape of the elastic contact element 1 is more speci...

Embodiment 2

[0079] 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 .

[0080] 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

[0085] 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.

[0086] 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

Disclosed is an electric connector equipped with an elastic contact element and used between boards. The electric connector comprises a substrate and at least one elastic contact element, wherein each elastic contact element comprises a plurality of unit spiral rings which are connected end to end in sequence along a trajectory; the unit spiral rings are formed by linear conductive bodies in a winding manner; the section of the elastic contact element is of a dual-oval structure; the substrate comprises a board-shaped body and a clamping tongue, and a clamping gap is formed between the board-shaped body and the clamping tongue; and the elastic contact element is clamped in the clamping gap to enable the side part of the elastic contact element to be in contact with the board-shaped body to form electrical connection. By adoption of the electric connector equipped with the elastic contact element provided by the invention, the quantity of contact points is doubled; when the section area of the liner conductive bodies is unchanged, the current-carrying capability is doubled; and when the current-carrying capability is unchanged, the section area of the liner conductive bodies is reduced, so that cost is lowered.

Description

technical field [0001] The present invention relates to the technical field of electrical connectors, in particular to an electrical connector with elastic contact elements used between boards. Background technique [0002] In an electrical connector, the contact area of ​​the electrical connection is an important indicator to measure the reliability of the connection, especially for electrical connectors that work under high current.
