Described shell, an end opening, the other end are provided with the shell circular hole, and cable from then on hole inserts, and is provided with four screws around the inwall, installs with the inner core framework, and shell adopts special material to make waterproof and dustproof, antistatic.

Described contact pin, be divided into the male and female contact pin, cable is colded pressing with contact pin and is connected, determine the male and female end of its contact pin according to the difference of the position of assembly control cubicle that two ends are inserted into, also come the color or the overlay coating of determining section contact pin according to the medium (signal or big electric current) of the required transmission of cable, what transmission performance was had relatively high expectations is gold-plated-golden contact pin, and other then are silver-plated-silver color contact pin, and the aperture of cold end terminal afterbody is selected according to carrying out cable footpath size.

Described inner core, can be divided into male end and female end, and two ends are 6 holes, inner core is fixed by screw with the inner core framework, be provided with four nuts around the inner core framework, screw fixingly with the screw around the shell, the male end of contact pin and inner core male end are corresponding installs, the corresponding fixed installation of the female end of contact pin and inner core female end.

The utility model installation procedure is: during installation, the cable joint bonnet is taken off, pack into connector shell afterbody and tighten with monkey wrench, be provided with sealing ring in the cable joint, the cable joint bonnet screwed be enclosed within on the cable, cable adopts the mode of colding pressing to be connected with contact pin, in-core in contact pin inserts, the male plug pin inserts public inner core, the female plug pin inserts female inner core, adopt the plastic buckle shell fragment to be connected or other elastic connection ways between inner core and the contact pin, inner core is fixed in the inner core framework, and inner core framework and shell screw install and fix.

Owing to adopted above technical scheme, the beneficial effect that the utlity model has is as follows:

1, installation is simple, easy to maintenance;

2, conduction efficiency height, water proof and dust proof, charged magnetic screen function, can adapt to adverse circumstances such as high temperature, humidity.

3, be applicable to the field condition of complexity such as desert, beach, sea or the situation that requires high efficiency to install, plug and play, simultaneously also can save great deal of labor in the middle of follow-up maintenance, it is little that heavily loaded cable assembly has the interface size, characteristics such as reliability height.
