Abstract
A spring type jack contact element comprises a spring and a jack, wherein two steps are arranged at the contact end of the jack contact element, axial grooves are uniformly formed, the inner diameter size of the spring corresponds to the size of the jack after the jack is closed, and the spring is sleeved between the two steps at the end part of the jack. According to the spring type jack contact element, as the jack is not subjected to die necking treatment, the defect of jack necking is avoided; the separating force is ensured by the spring, the size parameter of the spring is stable, the rigid contact pin contact piece can be ensured to be inserted and pulled out for many times, and the separating force is stable.
Description
Technical field
The present invention relates to a kind of jack contact, belong to technical field of electric connectors.
Background technology
The contact specification kind of electric connector is various, and conventional connector plug jack contact generally adopts mould to carry out necking forming, thereby contact pin contacts with the inwall formation pressure of jack reducing when guaranteeing that the rigidity contact pin inserts jack.After jack carries out die forming in the course of processing, also need carry out the separating force Screening Treatment, and owing to use elastomeric material to be out of shape reducing, material is easy to resilience or plastic deformation causes connector separating force instability.
Summary of the invention
The purpose of this invention is to provide a kind of spring-loaded type socket contact element structure, utilize structural advantage, eliminate the defective of existing conventional jack manufacturing process.
Spring-loaded type socket contact element of the present invention is made up of spring, jack, and the jack contact contact jaw is provided with two steps, and contact jaw circumferentially evenly is provided with axially grooved, and the spring size is corresponding with jack closing in back size, is sleeved between two steps of jack end.
More than the described number of coils 2 circles, the fluting quantity between two steps of jack end is more than 2, preferred 3-5 bar.
The jack of spring-loaded type socket contact element of the present invention directly is shaped by machining, and spring carries out structural design according to the closing in degree that jack need be realized, the jack oral area with fluting during assembling closes up the assembling that the cover upper spring can realize inserting the spring jack.Do not handle because jack does not carry out the mould reducing, the defective of jack reducing can not occur; And the separating force of spring jack guarantees by spring, it is stable that spring processes the back dimensional parameters, in certain deformation, can swell repeatedly and dwindle and do not produce plastic deformation, can guarantee that the rigidity contact pin contacting piece repeatedly inserts and extracts, obtain stable separating force.

Embodiment
As shown in the figure, spring jack contact of the present invention is made up of spring 1, jack 2, and the jack contact contact jaw is provided with one and protrudes step 4, and oral area is a flange step 3, and contact jaw circumferentially evenly is provided with 4 flutings 5, as shown in Figure 3; The spring inside diameter size is corresponding with jack closing in back size, is sleeved between two steps of jack end.
