Embodiment 1

[0042] An electrical contact with elastic contact elements, which 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, thereby saving cost, and also reducing the space occupied by the electrical contact.

[0043] Such as 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 spiral rings 2, a plurality of unit spiral rings 2 along a track line Connected end to end in turn; 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...

Embodiment 2

[0078] In order to improve the stability of the electrical contact with the elastic contact element of the present invention and prevent the decrease in electrical conductivity due to deformation, the difference between this embodiment and the first embodiment is that the elastic contact element 1 also includes a support 4. The support 4 is arranged inside the elastic contact element 1, and further, the outer wall of the support 4 is partially or completely adhered 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 4 is in contact with the inner wall of the elastic contact element 1, wherein the support 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 4 makes The first fixed contact portion 214 and the second...

Embodiment 3

[0084] When the electrical contact is working for a long time under high current or in the working state for a long time, it will generate a lot of heat, 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 elastic contact elements with a built-in liquid cooling medium, which can continuously take away the internal heat of the electrical contact during the working process of the electrical contact, and ensure a constant temperature inside the electrical contact , So as to ensure good conductivity of the electrical contacts.

[0085] The difference between this embodiment and embodiment 1 is that: the electric contact piece with elastic contact element with built-in liquid cooling medium includes elastic contact element 1 and liquid cooling pipe 5; the liquid cooling pipe 5 is arranged on the e...

Abstract

An electrical connector with a pin contact comprises the pin contact, wherein the pin contact comprises a conductive pin and at least one elastic contact component; the outer wall of the conductive pin is provided with a receiving groove for mounting the elastic contact component; the elastic contact element includes a plurality of spiral unit rings; the plurality of spiral unit rings are connected from end to end along a trajectory; each spiral unit ring is formed by a linear conductor in an encircling manner and the section shape of each elastic contact component is a double ellipse; and the trajectory has a spiral shape. According to the electrical contact with the elastic contact component, the number of contact points is doubled, when the cross-sectional area of the linear conductor is unchanged, the current carrying capacity is doubled; and when the current carrying capacity is unchanged, the cross-sectional area of the linear conductor can be decreased so as to save the cost.

Description

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