Problems solved by technology

However, the contact finger structure of the single-wire coil spring is an unstable structure. After a long storage period, the stress of the spring finger structure is released, which may cause the bite force / insertion force to increase to unusable; during the life cycle of the contact piece, the bite force The separation force and separation force decrease with the increase of the number of plugging and unplugging, there is a risk of reduced reliability, and it is difficult to meet the requirements for reliability and longer life of the contacts in the electrical connection structure

Embodiment 1

[0039] reference figure 1 with figure 2 As shown, the outer circumference of the support 1 is provided with a plurality of winding grooves 11, and the two ends of each winding groove 11 respectively extend to the two ends of the support 1; each conductive member 2 is respectively wound around the outer circumference of the support 1 along a single winding groove 11 , And a plurality of conductive elements 2 can be connected to each other.

[0040] The support can be a wire with a circular, elliptical, square, polygonal or other shape in cross section. After the winding groove is provided, the outer circumference of the cross section of the support is zigzag. The winding groove provided on the outer periphery of the support member can guide and support the conductive member. The supporting member can be a conductor or an insulator. Since the supporting member mainly functions to support the external conductive member, its conductivity can be selected as required.

Embodiment 2

[0042] In this embodiment, the supporting member 1 is not provided with a winding groove on the circumference, but the outer surface is smooth, and the conductive member 2 is directly wound around the smooth outer circumference of the supporting member to form an elastic winding contact element. When the elastic wire-wound contact element is bent as a whole, the supporting member 1 can also support the conductive member 2 wound on the outside thereof, thereby improving structural stability and prolonging the service life. This embodiment is not the focus of protection of the present invention and will not be repeated.

Embodiment 3

[0044] On the basis of embodiment 1 or embodiment 2, in this embodiment, the elastic wire-wound contact element formed by winding the conductive member 2 on the support 1 is integrally bent, that is, the support member is bent into a ring shape. The contact element can be applied to the pin or socket, and the electrical connection performance is reliable. In this case, in order to finally form a multi-contact conductive whole between the plurality of conductive members 2, that is, the plurality of conductive members can be electrically connected to each other, the winding method of the plurality of conductive members on the support member There are also many kinds, the following preferably, each winding groove is arranged in a spiral manner on the outer periphery of the support member in parallel to expand the embodiment:

Abstract

The invention discloses an electric connector equipped with a helical elastic winding type contact element in a contact pin contact part. The contact pin contact part comprises a contact pin body and the helical elastic winding type contact element; the helical elastic winding type contact element comprises a supporting part and a plurality of linear conductive parts; the supporting part is bent and helical, and multiple winding grooves are formed in the periphery of the supporting part; the two ends of each winding groove extend to the two ends of the supporting part separately; each conductive part is wound around the periphery of the supporting part along each single winding groove, and the multiple conductive parts are connected mutually; and the helical elastic winding type contact element is arranged on the periphery of the contact pin body in a sleeving manner. By virtue of the helical elastic winding type contact element, inserting-connecting type electric connection is realized, and electric connection reliability of the contact pin contact part and the electric connector applying the same is improved; and in addition, the elastic contact element, the contact pin contact part and the corresponding electric connector are relatively long in service life, and the structural stability is relatively high.

Description

Technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a pin connector with spiral winding contacts. Background technique [0002] In the prior art, the plug-in electrical connection structure generally achieves electrical connection through direct contact between the pin and the socket. Due to factors such as technological constraints, this plug-in type has poor electrical connection reliability and is used many times for a long time. Plugging and unplugging will result in poorer reliability and shorter life span. [0003] At the same time, 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 contact or the electrical connector that works under a large current. The electrical contacts in the prior art, such as pin contacts or jack contacts, are generally electrically connected by single-wire coil springs ...
