Electrical connector with pin contact piece

Abstract

The invention discloses an electrical connector with a pin contact piece. The electrical connector comprises the pin contact piece, wherein the pin contact piece comprises a conductive pin and at least one spiral elastic contact component, an accommodating groove is formed in an outer wall of the conductive pin and is used for installing the spiral elastic contact component, the spiral elastic contact component comprises a plurality of unit spiral rings, the plurality of unit spiral rings are sequentially connected in an end-to-end way along a spiral track 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, the deformable contact part is of a bending structure and comprises a guide region, a deformation region, a contact guide region and a bulge of the deformation region, and the bulge is arranged at one side of a midperpendicular of a connection line of a top point of the first transition part and a top point of the second transition part. The electrical connector has relatively high contact performance, the guide region simultaneously has effects of guidance and deformation, and thus, electrical contact of a pin used with the electrical connector in a matching way or the other electrical connectors can be achieved within short stroke.

Description

technical field [0001] The invention relates to an electrical connector with pin contacts, belonging to the technical field of electrical contacts. Background technique [0002] In electrical connectors, the contact area between pins and sockets in a connector is an important index to measure a contact, especially for connectors working under high current. In the prior art, single-wire helical springs are generally used for multi-contact electrical connection. The retrieved published patents include: CN102427180A, CN102522647A, CN102570115B, CN102810782B, respectively described as follows: [0003] The patent application document with publication number CN102427180A discloses a spring contact finger, a socket and a socket system, wherein the spring contact finger includes an oblique elliptical spring finger, and the first angle 4 is the angle between the second plane 9 and the first plane 11 , the second angle 5 is the included angle between the second plane 9 and the third...

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
