Abstract

The utility model discloses an auto-branch electric wire and cable, being characterized in that a plurality of metal conductors are arranged in an insulating sheath of a main wire; the insulating sheath is arranged outside each metal conductor to form a wire; random number of wires are divided at multi positions in random distance between two adjacent positions of the main wire, and are led out through an end socket at the same time; an insulating sheath forms a branch wire outside the led-out wire at each position; the branch position of the main wire and the root of each branch wire are respectively provided with a fixed body for strapping the wires, thus making the overall electric wire and cable be secured and reliable; and each branch wire is connected with a fuse in series. In conclusion, the auto-branch electric wire and cable can replace the bus duct wiring with poor safety and high price in the application to electrical distribution for high-rise buildings; the contactless electrical performance is also significantly better than a prefabricated branch cable; and at the same time, the auto-branch electric wire and cable can be protected by the fuses when the current for the branch wires is over large, thus avoiding expansion of the loss and being widely applied to the occasions, such as tunnels, subways and an anti-explosion environment.

Description

Autogeny type branching wire cable

Technical field

The utility model relates to the electric wire field, is specifically related to the electric wiring distribution and replaces the bus duct distribution or pay the electric wire of formula distribution in advance.

Background technology

Present electrical power distribution system used in skyscraper, tunnel, subway, if when circuit needs to adopt branch's form, one adopts bus duct and pays the formula branch cable in advance and satisfy requirement of engineering.But these two kinds of modes all exist branch line and backbone that the problem of contact-making surface is arranged, and unavoidably bring connection reliability and the cold and hot performance issue of more unmanageable overcurrent.

In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.

The utility model content

The purpose of this utility model provides a kind of Autogeny type branching wire cable, to solve existing bus duct and to pay the above problem that the formula branch cable exists in advance.

For reaching the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of Autogeny type branching wire cable is provided, it is characterized in that: in the insulation sheath of backbone some metallic conductors are set, every metallic conductor arranges the insulation sheath outward and forms wire, tell any root wire for the many places of any distance between adjacent two places of backbone and draw by end socket simultaneously, the wire that draw the everywhere arranges the insulation sheath outward and forms branch line; Backbone bifurcation and branch line root arrange respectively the fixed body of tying up wire, make whole wire electricity system solid and reliable; Every offset serial connection fuse.

In sum, the relatively poor and expensive bus duct distribution of Autogeny type branching wire cable provided by the utility model alternative security performance in the application of skyscraper electrical power distribution, contactless electric property also is better than the prefabricated branch cable greatly.Simultaneously, can obtain the fuse protection when offset electric current is excessive, avoid loss to enlarge.Therefore this cable in the tunnel, subway and explosion-proof environment occasion can both be widely used.

Fig. 1 is structural representation of the present utility model.

Wherein, 1, backbone; 2, branch line; 3, end socket; 4, wire; 5, insulation sheath; 6, metallic conductor; 7, fixed body; 8, fuse.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

-as shown in Figure 1, the insulation sheath 5 interior some metallic conductors 6 that arrange of backbone 1, the every metallic conductor 6 outer insulation sheaths 5 that arrange form corresponding some wires 4, tell any root wire 4 for the many places of any distance between adjacent two places of backbone 1 and draw by end socket 3 simultaneously, the wire 4 outer insulation sheaths 5 that arrange that draw the everywhere form branch line 2.Wire 4 in the branch line 2 does not continue in backbone 1 interior extension, and the total sectional area of backbone 1 interior metallic conductor 6 reduces gradually.Backbone 1 bifurcation and branch line 2 roots arrange respectively the fixed body 7 of tying up wire 4, make whole wire electricity system solid and reliable.Every offset 4 serial connection fuses 8.

Branch line 2 on backbone 1 the place of drawing and draw quantity and design as required, and finish manufacturing in factory, can guarantee the quality of each end socket and the quality of whole cable.

Although by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection range of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection range of this patent.
