Abstract
The invention discloses an electrical connector with a contact piece locking structure, wherein a contact piece can be dismounted and replaced. The electrical connector comprises a housing, a contact piece, an insulated base and an insulated locking ring. The insulated base is provided with an installation hole. The contact piece is fittingly embedded in the installation hole of the insulated base. The outer side of the insulated base is provided with a groove matched with the insulated locking ring. The groove is connected with the installation hole. The contact piece is provided thereon with a groove. The insulated locking ring is hollow and annular and is provided with an opening. The inner side of the insulated locking ring is provided with a step embedded inside the groove of the contact piece. The insulated base and the contact piece are tightly and fixedly connected via the insulated locking ring. According to the technical scheme of the invention, the insulated locking ring type locking structure of the electrical connector is reliable in self-locking performance, wherein the contact piece can be easily dismounted and replaced without any special tool.
Description
Technical field
The present invention relates to electric connector field, especially a kind of electric connector with contact locking mechanism.
Background technology
Electric connector is made up of the large elementary cell of housing, insulator and contact three, and wherein contact is generally assembled in the housing by insulator.In some electric connectors, require that contact can be changed in unloading at any time, and current contact overlaps fixed form with tooth, therefore in the input fixing and need in unloading process tooth cover and extraction tool, but, often in the dismounting and Renewal process of contact, easily damage tooth overlaps and cost is had high input, and the mode assembly operation that tooth cover is fixed is complicated.
Summary of the invention
[technical problem that will solve]
The object of the invention is the problem solving above-mentioned prior art, a kind of electric connector with contact locking mechanism is provided.This electric connector due to edge insulator ring type locking mechanism have self-locking reliable, just without the need to special tool(s) can dismantle like a cork and change contact.
[technical scheme]
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
Have an electric connector for contact locking mechanism, it comprises shell, contact, insulating base and insulation snap ring; Described insulating base is provided with installing hole, and described contact coordinates chimeric with the installing hole on insulating base; Also be provided with the groove matched with the snap ring that insulate outside described insulating base, and described groove part is communicated with installing hole; Described contact arranges groove; Described insulation snap ring is the annular of opening, hollow, is provided with the step with the groove tabling on contact on inside described insulation snap ring; Described insulating base is closely fixedly connected with by insulation snap ring with contact.
The present invention is technical scheme further, and the step on described insulation snap ring has 2 at least.
The present invention is technical scheme further, and described insulation snap ring passes through compression molding.
The present invention is technical scheme further, and described insulation snap ring is prepared from by nylon PA6 material.
The present invention is technical scheme further, described in there is contact locking mechanism electric connector be also provided with insulation claw, described insulation claw comprises claw body and at least one pawl head.
The present invention will be explained below.
The present invention is by the groove on insulating base, insulation snap ring is fitted together to into, and because groove part is communicated with installing hole, when contact devices inserts on position, the corresponding mounting hole hole, owing to contact there being corresponding depression, this depression is closely fitted and fixed with the step part of insulation snap ring, thus achieves contact and be closely fixedly connected with insulating base.And by the opening on insulation snap ring, just without the need to special tool(s) can dismantle like a cork and change contact.The planform of the insulation snap ring in the present invention is determined according to the positional alignment of contact in insulating base and contact dimensions.The present invention have also been devised insulation claw and is fixed by cable and prevent it from rotating.
[beneficial effect]
The present invention compared with prior art, has following beneficial effect:
The contact dismounting of electric connector of the present invention and replacing are conveniently, relative to traditional tooth cover fixed contact therefor mode, decrease the input of tooth cover and extraction tool, prevent the damage to tooth cover in Renewal process, loss rate that input cost is lower, part gives up is low, assembly operation is simple, and ensure that the reliable connection of electric connector better, thus ensure that properties of product well.And electric connector of the present invention will be used widely in various fields such as track traffic, new-energy automobile, Engineering Control.
