Problems solved by technology

However, the oblique configuration of the contact fingers of the single-wire coil spring is an unstable configuration; the stress release of the oblique configuration of the product during a long storage period may cause the bite force / insertion force to increase to unusable; during the product life cycle, the bite force and separation Generally, it decreases with the increase of the number of plugging and unplugging, and there is a risk of reduced reliability, such as increased temperature rise and difficulty in meeting higher service life requirements

Embodiment 1

[0054] An electrical contact piece with an elastic contact element, comprising: an elastic contact element 1, the elastic contact element 1 includes a plurality of unit spiral rings 11, and the plurality of unit spiral rings 11 are sequentially connected end to end along a track line; the unit The spiral ring 11 is helically surrounded by a linear conductor. As shown in Fig. Two transition portions 15; the deformable contact portion 12 is arranged as a bent structure, including a guide area 121, a deformation area 122, a protrusion 123 connecting the guide area and the deformation area, and the length of the guide area 121 is less than the length of the deformation area 122 ( That is, the length of the line between the two end points of the guide zone is less than the length of the line between the two end points of the deformation zone), and the protrusion 123 is located on the line between the apex of the first transition portion 14 and the apex of the second transition porti...

Embodiment 2

[0087] In order to improve the stability of the electrical contact piece with elastic contact elements of the present invention and prevent the decrease in electrical conductivity due to deformation, in this embodiment, the difference from Embodiment 1 is that it also includes a support member 2, and the support member 2 It is located inside the elastic contact element 1.

[0088] Further, the outer wall of the support member 2 is partially or completely attached to the inner wall of the elastic contact element 1 to support the elastic contact element 1 .

[0089] In this embodiment, all the outer walls of the support member 2 can be fully attached to the inner wall of the elastic contact element (as shown in Figure 9(a)), at this time, the support member 2 is made of elastic material; or the support member 2 is in contact with the inner wall part of the fixed contact part 13 (as shown in Fig. 9(b) or Fig. 9(c)), which is used to limit the movement distance of the protrusion 1...

Embodiment 3

[0093] 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 operation of the electrical contact, so as to ensure that the internal temperature of the electrical contact is constant. Good electrical conductivity of the electrical contact is thereby ensured.

[0094] The difference between this embodiment and embodiment 1 is:

[0095] The electrical contact with elastic contact elements with a built-in liquid cooling medium includes an elastic contact element 1 and a liquid cooling conduit 3 disposed inside the elast...

Abstract

The invention discloses an electric connector provided with a jack contact piece. The electric connector comprises the jack contact piece, wherein the jack contact piece comprises a jack main body and at least one annular elastic contact element; a containing groove for containing the annular elastic contact element is formed in an inner wall of the jack main body; the annular elastic contact element comprises a plurality of unit spiral rings; the unit spiral rings are sequentially connected in an end-to-end manner along a path line; each unit spiral ring comprises a deformable contact part, a first transition part, a fixed contact part and a second transition part which are sequentially connected; each deformable contact part is in a buckling structure, and comprises a guide area, a deformation area, and a bulge connected with the guide area and the deformation area; and each bulge is located on one side of a perpendicular bisector of a connecting line between a vertex of each first transition part and a vertex of each second transition part. The electric connector has high contact performance, and the guide areas of the electric connector have guide and deformation effects, so that electric contact of contact pins or other electric connecting devices matched with the electric connector for use can be realized in a short stroke.
