Abstract

The utility model discloses an electrical connector sealing structure comprising a sheath, a contact element and a wire. The sheath is a cylindrical rubber element, the inner circle of the sheath is provided with a stepped hole, and a plurality of grooves are formed in the hole in the radial direction. The insulating layer of the wire is provided with a plurality of ribs in the radial direction. The core of the wire is in electrical connection with the contact element. The wire and the contact element are arranged in the sheath. The ribs on the wire are clamped with the grooves in the sheath. According to the utility model, the structure in which the grooves are arrange in the sheath and the ribs are arranged on the wire is adopted so as to satisfy the requirements of the small-space wire making occasions, and advantages of simple structure, reliable sealing and convenient wire making can be realized.

Description

The hermetically-sealed construction of electric connector

Technical field

The utility model relates to technical field of electric connectors, relates in particular to a kind of hermetically-sealed construction of electric connector.

Background technology

Electric connector in use, be to guarantee the electric and mechanical performance of electronic devices and components, and good insulation and sealing property are absolutely necessary, and it is related to the functional reliability of electric connector and for the adaptability of various operational environments.

The electric connector sealing of prior art, conventionally adopts sealing ring or encapsulating is set between contact 2, wire and sheath, and tie tail annex or wire clamp, to reach the effect of electric connector tail seal.The problem existing is, this mode not only makes part increase, and cost increases, and the difficulty that causes scene to make line also increases, and not only operating efficiency reduces, and makees line and take up room greatly, and the occasion contradiction less for space is particularly outstanding.Therefore be necessary to design and a kind ofly seal reliable, simple in structure and can meet little space and do the hermetically-sealed construction that the field of line closes.

Utility model content

The purpose of this utility model is the hermetically-sealed construction of a kind of electric connector of providing for the deficiencies in the prior art, the utility model adopts the structure that convex tendon is set on groove, wire is set in sheath, to meet little space, do the occasion of line, have simple in structure, sealing is reliable and do line advantage easily.

The concrete technical scheme that realizes the utility model object is:

A hermetically-sealed construction for electric connector, its feature comprises sheath, contact and wire, described in protect the rubber parts into cylindrical tube shape, its inner circle is provided with shoulder hole, is radially provided with several groove in hole, is radially provided with several convex tendon on the insulating barrier of wire; The core of described wire is electrically connected to contact, and wire is located in sheath together with contact, and the convex tendon on wire and the groove clamping in sheath; The road number of described sheath inner groovy is corresponding with the road number of convex tendon on wire; Described groove and the cross section of convex tendon are circular arc, rectangle, triangle or trapezoidal.

The utility model adopts the structure that convex tendon is set on groove, wire is set in sheath, does the occasion of line to meet little space, have simple in structure, sealing is reliable and do line advantage easily.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model sheath.

Embodiment

Consult Fig. 1, Fig. 2, the utility model comprises sheath 1, contact 2 and wire 3, the rubber parts that described sheath 1 is cylindrical tube shape, and its inner circle is provided with shoulder hole, is radially provided with several groove 11 in hole, is radially provided with several convex tendon 31 on the insulating barrier of wire 3; The core of described wire 3 is electrically connected to contact 2, and wire 3 is located in sheath 1 together with contact 2, and groove 11 clampings in the convex tendon on wire 3 31 and sheath 1;

Described sheath 1 inner groovy 11 road number is corresponding with convex tendon 31 road number on wire 3;

Described groove 11 and the cross section of convex tendon 31 are circular arc, rectangle, triangle or trapezoidal.

The utility model is to make like this:

The utility model sheath 1 inner groovy 11 road number and number corresponding setting in convex tendon 31 road on wire 3, while making sheath 1, make to be interference fit between groove 11 and convex tendon 31, by means of the resilient characteristic of rubber sheath 1, to improve the sealing reliability of electric connector.

The utility model is to use like this:

Take in sheath 1 and be provided with twice groove 11 as example, first, sheath 1 is inserted in from the termination of wire 3, contact 2 is realized and being electrically connected to wire 3 welding or crimping, with hot pressing pincers, on the insulating barrier of wire 3, extrude twice convex tendon 31, sheath 1 is extracted to the direction of contact 2, until the groove 11 in sheath 1 is corresponding with convex tendon 31 on wire 3 and clamping, groove 11 on sheath 1 is fitted like a glove with the convex tendon 31 on wire 3, flexible rubber sheath 1 shrinks voluntarily, reaches the effect of contact 2 and wire 3 afterbodys and sheath 1 sealing.
