Description
Technical field
The utility model belongs to electric field, specifically refers to a kind of left side copper shell for crosslinked cable intermediate connector outside shielding copper shell.
Background technology
When the installation of long distance wiring or cable, the means that conventionally two cables will be connected together improve the length of cable.In cable, except including wire, conventionally also to include the insulating protective layer of screen and outside.When carrying out cable connection, must destroy screen and the insulating protective layer of junction.
For the insulating barrier of cable, as long as insulating tape etc. can be realized to insulation processing, but be not easy to realize with the protection intensity of junction.In addition, most important screen is very difficult to process, therefore, existing technology adopts the way of wearing helmet shell to cable junction to realize intensity to cable joint place and the processing of screen, but the existing helmet shell volume of using is large, uses inconvenient, and cannot reach the shield effectiveness of former cable, in joint, be easily subject to external influence, and then have influence on whole system, even sometimes whole system is brought to harm.
Utility model content
Of the present utility modelly be to provide a kind of left side copper skinning technique scheme for crosslinked cable intermediate connector outside shielding copper shell, by the technical program, can improve the shield effectiveness at cable joint position, prevent having pore to produce while carrying out encapsulating in the inside of copper shell, and convenient operation.
The utility model is achieved through the following technical solutions:
A left side copper shell for cable intermediate joint, includes interior copper pipe, outer copper pipe and is arranged at the insulating barrier of interior copper pipe outer surface and outer copper pipe surfaces externally and internally; Described insulating barrier is structure as a whole; The external diameter of described interior copper pipe is less than the internal diameter of outer copper pipe, one end of interior copper pipe and one end of outer copper pipe by insulating barrier, be fixedly connected with but in copper pipe with outer copper pipe without being electrically connected;
One end of described interior copper pipe extend into one end of outer copper pipe, and the axial cross section that is arranged at the left side copper shell of the insulating barrier between interior copper pipe outer surface and outer copper pipe inner surface is U-shaped.
Described outer copper pipe and interior copper pipe away from one end be provided with jockey.
Described jockey is flange arrangement.
It is exposed layer that described interior copper pipe has part outer surface away from the side surface of one end of outer copper pipe, is not insulated layer and covers.
The beneficial effects of the utility model are:
Pass through the technical solution of the utility model, can improve the shield effectiveness at cable joint position, by the U-shaped structural design between interior copper pipe and outer copper pipe at left side copper shell, improved the combination effect that pours into copper enclosure colloid and copper shell and cable joint, prevented axially or radial rotating.
Accompanying drawing explanation
Fig. 1 is the left side copper shell mechanism schematic diagram of the utility model copper shell.
Embodiment
