Abstract

The utility model discloses a kind of security protection rat tail, including principal wire bundle and be arranged on principal wire bundle both ends connection computer end the first plug receptacle and the second plug receptacle, the inner core of the principal wire bundle is made up of some coaxial lines, the coaxial line is from the inside to the outside successively by conductor, inner insulating layer, braiding layer and the outer layer that drapes over one's shoulders form, the braiding layer is covered in the inner insulating layer of conductor, and coiled conductor spirally is formed, the utility model is using main wire rod of the coaxial line as security protection wire harness, reduce the copper foil layer that wire rod relatively common at present uses inside it, it is soft compared to existing coaxial line, and shield effectiveness is good, braiding layer is covered in the inner insulating layer of conductor, and coiled conductor spirally is formed, further increase the shield effectiveness of wire rod.

Description

A kind of security protection rat tail

Technical field

Wire harness technical field is the utility model is related to, more particularly to a kind of security protection rat tail.

Background technology

Security protection wire rod is in safe protection engineering project, for transmission video signal, control signal and other data messages Wire rod be referred to as security protection wire rod, at present, various safety monitoring wire rods are different according to the field that uses, and the standard followed is also not to the utmost It is identical.And more commonly used coaxial line is all the interior wire rod containing copper foil layer at present, its pliability is poor, and line is harder.

The content of the invention

In order to overcome drawbacks described above, the utility model provides a kind of security protection connection that can solve the problem that above mentioned problem Wire harness.

The utility model in order to solve its technical problem used by technical scheme be：A kind of security protection connecting line Beam, including principal wire bundle and the first plug receptacle and the second plug receptacle that are arranged on principal wire bundle both ends connection computer end, the main line The inner core of beam is made up of some coaxial lines, and the coaxial line drapes over one's shoulders by conductor, inner insulating layer, braiding layer and outside successively from the inside to the outside Layer composition, the braiding layer is covered in the inner insulating layer of conductor, and coiled conductor spirally is formed.

As further improvement of the utility model, the line footpath of the principal wire bundle is less than 3.0mm.

The beneficial effects of the utility model are：The utility model is using main wire rod of the coaxial line as security protection wire harness, Reduce the copper foil layer that wire rod relatively common at present uses inside it, it is soft compared to existing coaxial line, and shield effect Fruit is good, and braiding layer is covered in the inner insulating layer of conductor, and coiled conductor spirally is formed, and further increases the screen of wire rod Cover effect.
