Abstract
The invention relates to a cable, in particular to a water-blocking branch cable for rail traffic. The water-blocking branch cable for rail traffic comprises a connecting head made of an elastic waterproof material, a main cable and a branch cable body, wherein the connecting head is provided with two main through holes in the same straight line and a branch through hole; the main cable is provided with a joint; a center conductor of the main cable is connected with a center branch conductor of the branch cable body through a branch joint; a hoop is arranged at the outer part of each main through hole in a sleeving way to perform fastening; the two main through holes of the connecting head are respectively fixed on the two sides of the joint of the main cable; the branch through hole is fixed in the joint of the branch cable body; a branch hoop is arranged at the outer part of the branch through hole in a sleeving way to perform fastening; a main body is arranged between the two main through holes of the connecting head; the branch through hole is formed in the top of the main body; and a fixed plate is fixed at the bottom of the main body and is arranged on a bracket of an external lead. According to the water-blocking branch cable for rail traffic, provided by the invention, the branch cable body and the main cable are connected flexibly, so power outage accidents are avoided.
Description
Technical field
The present invention relates to a kind of cable, specially waterproofing type track traffic branch cable.
Background technology
Branch cable is to be widely used in the distribution systems such as house, office tower, tunnel, hotel, hospital, market,
Can be used for mobile jib line has the illuminator (highway, bridge, tunnel and airfield runway) of branch line requirement.As track traffic is sent out
Exhibition, the branch cable demand of track is increasing, and as using on the in rail vehicles, cable connector is easily received
To larger vibrations and external impacts, branch's junction fracture is caused.
Content of the invention
For above-mentioned technical problem, the present invention provides a kind of electricity that can effectively prevent branch cable junction from rupturing
Cable.
The technical solution used in the present invention is：
Waterproofing type track traffic branch cable, the union joint that makes including elastic water-proofing material, leader cable and branch cable, institute
The union joint that states has two main through holes on the same line and branch's through hole, has junction on described leader cable, main
The center conductor of cable props up conductor by branch joint with the center of branch cable and is connected, and being cased with clip outside main through hole is carried out tightly
Gu；Two main through holes of described union joint are separately fixed at the both sides of leader cable junction, and described branch's through hole is fixed on
The junction of branch cable, is cased with branch's clip and is fastened outside branch's through hole；Two main through holes of described union joint
Between be main body, branch's through hole is fixed with fixed plate in the top of main body, the bottom of described main body, and fixed plate is placed in outside
On the support of wire.
Described fixed plate includes a raised boss, and the bottom of union joint main body is arranged on boss, the bottom of clip
Portion props union joint by boss and clip in the fixed plate of the both sides of boss, two main via bottoms and fixed plate it
Between formed gap.
The part that the bottom of union joint main body is contacted with boss is groove, is filled with buffer board in groove.
The main connection of described branch's through hole and the branch junction, two main through holes and union joint main body of union joint main body
Place is bellows-sheathed.
Described branch joint is the structure of hollow cylindrical, and cylindrical outer wall props up conductor admittedly with the center of branch cable
Fixed connection, the hollow sleeve of branch joint is on the center conductor of leader cable.
The waterproofing type track traffic branch cable that the present invention is provided, will be firm between original branch cable and leader cable
Property connection change flexible connection, can effectively improve the bonding strength of union joint, it is to avoid the loss of power accident occurs.
Description of the drawings
Fig. 1 is the part section structural representation of the present invention.
Specific embodiment
The specific embodiment of the present invention is described with reference to the drawings, as shown in figure 1, waterproofing type track traffic branch cable,
Union joint 3, leader cable 1 and the branch cable 2 that makes including elastic water-proofing material, described union joint 3 has two with always
Main through hole 11 and branch's through hole 12 on line, the center conductor for having junction, leader cable 1 on described leader cable 1 passes through
Branch joint 4 props up conductor 7 with the center of branch cable 2 and is connected, and is cased with clip 9 and is fastened outside main through hole 11；Described connection
3 two main through holes 11 are separately fixed at the both sides of 1 junction of leader cable, and described branch's through hole 12 is fixed on branch cable
2 junction, is cased with branch's clip 8 outside branch's through hole 12 and is fastened；
Be main body between two main through holes 11 of described union joint 3, branch's through hole 12 at the top of main body, described main body
Bottom is fixed with fixed plate 5, and fixed plate 5 is placed on the support of outer lead.
Described fixed plate 5 includes a raised boss 14, and the bottom of 3 main body of union joint is blocked on boss 14
