Description

The protector of electric connector socket insulating base

The utility model relates to a kind of protector on the insulating base in the electric connector socket that is used in, belong to technical field of electric connectors.

Prior art (ZL92229049.0), it is as the electric connector on the railroad train, with its socket integral installation after on the train carriage, because the installation site on the compartment is a kind of and extraneous space that isolates of not having, can not dust and moisture, cause the insulating base in the socket, terminals together with each sleeve (hole), among all outer open space that is exposed in the box body, therefore insulating base is easy to be subjected to dust, the direct invasion and attack of moisture even moisture content and foreign material are polluted, and can accumulate gradually and be the moist plaster dirt of one deck, cover on the plate face of insulating base, form a conductive layer, make the insulation resistance of insulating base seriously descend, when dropping to required standard as its insulation resistance of insulating base between each circuitry phase of isolation and each circuitry phase and Socket casing, train just can't normal power-up move, especially electric train more likely is forced to the tripping operation outage, can not move.

The purpose of this utility model is the defective at above-mentioned existence, has proposed a kind of protector that can avoid polluting on electric connector, to guarantee the safe operate as normal of insulating base in the electric connector socket.

Technical solution of the present utility model:

Form by a guard shield 1 and four 2,3 of sheaths, the outer perimeter of its guard shield 1 is shaped on one group of profile of tooth circle 13, can be adjacent to the hole wall of socket bottom outlet, the horn mouth 15 that guard shield 1 middle part has four each terminals of confession to pass, horn mouth 15 inwalls are shaped on one group of profile of tooth circle 16, the periphery of terminals 7 can be pasted to pack tightly, and the periphery of horn mouth 15 is shaped on recessed circle 14, be with

sheath

2,3 on protruding circle 20 be interlockingly connected, also have four screwing through hole 18 on the guard shield 1.

Sheath

2,3 has totally four of long and short two kinds, can be enclosed within on the corresponding terminals respectively,

sheath

2,3 is made the bellows-like structure of bending shape, the one end mouth of pipe is made one section tapered aperture 21, can with the cable socket, be shaped on protruding circle 20 in the other end mouth of pipe, can with recessed circle 14 snappings on the horn mouth 15.

Guard shield 1 is made disc, and reinforcement 19 is arranged in the dish, and guard shield 1 can be pressed in the socket bottom outlet, and its end face and reinforcement 19 are fitted with insulating base.

Steel wire ring recess 17 is arranged in the horn mouth 15, in put spring steel wire coil 6 to support horn mouth 15.

Advantage of the present utility model:

1, adopts guard shield and sheath, tight insulating base together with all terminals, terminal and the whole seal closures of cable head, they are isolated from the outside, and the insulation resistance of insulating base just can not be subjected to the invasion and attack of outside water, ash and foreign material and the influence of pollution, guarantees its safety and operate as normal.

2, adopt guard shield and the assembly unit of sheath bulk-breaking, easy for installation.

3, one of the guard shield outer rim group of profile of tooth circle can make guard shield easy for installation and be adjacent to sealing with socket bottom outlet inwall.

4, one group of profile of tooth circle in each horn mouth on the guard shield can be adjacent to sealing with the terminals periphery.

5, the sheath of bending shape bellows-like structure can satisfy the installation of binding post at any angle.

6, the utility model is used for train, can not change installing space and size on the railway carriage.
