Abstract
The invention discloses a mineral cable multi-core intermediate connector, belongs to the field of cable installation, and solves the problems that the traditional intermediate connector is troublesome to install and has poor degree of safety of installation, and conductors cannot be tightly connected. The mineral cable multi-core intermediate connector mainly comprises an internal threaded seamless pipe, wherein the two ends of the internal threaded seamless pipe are respectively provided with a gland sealing end, and at least one screwed connection intermediate connecting terminal is arranged in the internal threaded seamless pipe. The mineral cable multi-core intermediate connector provided by the invention has the advantages of simple and convenient installation, high strength and safety, tight connection between the cable conductors, good conductive effect, simple structure, easiness in manufacturing, and high practical value, and can be widely applied in the field of cable installation.
Description
Technical field
The present invention relates to a kind of cable connecting arrangement, specifically, particularly relate to a kind of mineral cable multicore intermediate connector.
Background technology
Because mineral insulated cable production length is by the restriction of cable raw material length, or by the impact that different electric loop cable is equipped with in unwrapping wire process, make in cable laying installation process, need to adopt intermediate connector to be connected together by two same size cables, to ensure the needs meeting line length.
Now in practice, no matter the basis brass pipe that adopts, as outer sheath tube, is that single core or multicore inside adopt copper aluminium hydraulic pressed connecting pipe to carry out crimping connection more.China Patent No. CN 102468640A, date of publication on 05 23rd, 2012, the name of innovation and creation is called Special intermediate connector for fireproof cables, this application case makes public for the first time a kind of intermediate connector connected together by cable, although have fire-proof function, the connection that the internal structure of this application case still adopts traditional copper aluminium hydraulic pressed connecting pipe mode to carry out between cable.Traditional this connected mode, install trouble, especially multicore, each needs carries out crimping work, and trouble degree more highlights.In addition, install security intensity also more weak, the connection defective tightness between cable conductor, thus it is poor to show conductive effect, what have even there will be cable obscission.
Summary of the invention
The invention discloses a kind of mineral cable list core intermediate connector, trouble is installed for solving traditional intermediate connector, the problem connecting defective tightness between weak, the conductor of degree of safety is installed.
The present invention is achieved by the following technical solutions:
A kind of mineral cable multicore intermediate connector, comprise internal thread seamless pipe, described internal thread seamless pipe two ends are respectively provided with a gland head end-blocking, are provided with splicing ear in the middle of at least one screw connecting-type in described internal thread seamless pipe.
In the middle of described screw connecting-type, splicing ear comprises special copper pipe, and any one side of described special copper pipe is provided with some screw holes and corresponding fastened by screw nail.
Any one side in the middle of described screw connecting-type on splicing ear is provided with pry hole.
The material of described internal thread seamless pipe is alloy brass pipe or T2 copper tube.
Compared with prior art, the invention has the beneficial effects as follows:
1. simple installation of the present invention, Strength Safety is high, and cable conductor connects closely, and conductive effect is good;
2. structure of the present invention is simple, is easy to manufacture, and practical value is high, can be widely used in cable installing area.
