Description
Technical field
The utility model relates to cable, more particularly to it is a kind of can stretch it is convenient and can installing and dismounting repeatedly minerals it is exhausted
Edge cable.
Background technique
Nuclear power station and the mineral insulated cable in other places are usually all using the coiled supply of material, after cable installation just
It is fixed on certain position for a long time, but for mineral insulated cable used in part test device or laboratory, it is necessary to often
Property connection, disconnect, and existing mineral insulated cable shell is metal material, and flexible opposite rubber cable is poor, not side
Just installing and dismounting, and will cause the fracture of mineral insulated cable shell or deformation when regular connection, disconnection.
Utility model content
Above of the existing technology to solve the problems, such as, the utility model proposes a kind of telescopic mineral insulation electricity
Cable, be a kind of flexible convenience and can installing and dismounting repeatedly mineral insulated cable.
The utility model can be resolved by the following technical programs:
A kind of telescopic mineral insulated cable of the utility model, including bellows, bellows connection sheet, connection
Pipe, soldering lug, electrical cnnector, mineral insulated cable and spring, one end of the mineral insulated cable and spring are together
Bellows is penetrated with spiral shape, the bellows and bellows connection sheet are brazed, and the bellows connection sheet and connecting tube are welded,
The mineral insulated cable and spring weld in the connecting tube with the soldering lug, and the soldering lug is connect with bellows
Piece welding, the electrical cnnector and the connecting tube are welded；The mineral insulated cable two-end structure is identical.
One end of the mineral insulated cable is equipped with handle as a preferred technical solution, and the handle passes through handle
Bracket is welded in the connecting tube.
The mineral insulated cable is processed into spiral size identical with spring and with more as a preferred technical solution,
The binding of root band, the band quantity of each spiral coil are no less than 2.
The band is metal material as a preferred technical solution,.
The mineral insulated cable is by mineral insulated cable shell, core wire, minerals as a preferred technical solution,
Insulant is drawn together, is heat-treated an armored cable of formation.
The mineral insulated cable shell is stainless steel tube or copper pipe as a preferred technical solution,.
The mineral insulation object is magnesia, aluminium oxide or silica as a preferred technical solution,.
The core wire quantity is according to the optional single of structure or multicore of cable as a preferred technical solution,.
The material of the spring is spring steel material as a preferred technical solution,.
The quantity of the mineral insulated cable can tie for one or more with spring as a preferred technical solution,
It ties up.
The beneficial effects of the utility model are:
1. cable and spring are brazed with soldering lug together, positional shift will not be generated when the two being made to stretch, compress, it is ensured that electricity
Cable can be with spring synchro-draw, compression；
2. the cable of assembled formation can be compressed and be stretched, no longer after application active force, cable can be returned to original shape
State, and may be reused, facilitate the installation and removal that user is regular, moreover it is possible to save space；
3. handle is arranged in cable end, it is easy for installation and removal；
4. having bellows outside cable and spring, cable and again beauty can be protected.
