Abstract
The utility model discloses a kind of four contact wiring harness structures, including cable, pipe fitting and bellows, the cable is interspersed in pipe fitting, and pipe fitting is provided at both ends with external screw thread, one end of external screw thread and bellows matches, and bellows-sheathed is outer loaded on cable and is rotationally connected on pipe fitting；It is also bundled with band on bellows, mark is installed on band.This four contact wiring harness structure, since pipe fitting is made of nylon, and both ends carry external screw thread, there is flute profile locking device in inside, the docking of bellows and connector can be realized, while can realize the locking effect to cable, cable is made to reach the degree of protection of IP68 in the sealing of joint；To realize the maintenance for realizing old vehicle with minimum cost, it is bad to significantly reduce the electrical contact because caused by being loosened at cable connection.
Description
Technical field
The utility model is related to locomotive couplers to connect electrical contact engineering device technique field, specially a kind of four contact line bindings
Structure.
Background technology
When existing part vehicle design the tolerance difference of cable size, which causes, not to be fully considered for electrical communications device
The cable of cable size limit on the lower side has loosening in joint, and steam is infiltrated through electrically by joint in rainy days or wet environment
Contact portion, it is bad so as to cause electrical contact.
Invention content
The purpose of this utility model is to provide a kind of four contact wiring harness structures, and the dimension of old vehicle is realized with minimum cost
Shield, significantly reduce because at cable connection loosen caused by electrical contact it is bad, solve the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions：A kind of four contact wiring harness structures, including electricity
Cable, pipe fitting and bellows, the cable are interspersed in pipe fitting, and pipe fitting is provided at both ends with external screw thread, external screw thread and wave
One end of line pipe matches, and bellows-sheathed is outer loaded on cable and is rotationally connected on pipe fitting；Band is also bundled on bellows,
Mark is installed on band.
Preferably, the pipe fitting is component made of a kind of nylon.
Preferably, the inside of the pipe fitting is equipped with the flute profile locking device of locking cable.
Compared with prior art, the beneficial effects of the utility model are as follows：
This four contact wiring harness structure, since pipe fitting is made of nylon, and both ends carry external screw thread, and there is flute profile locking in inside
Device, you can realize the docking of bellows and connector, while can realize the locking effect to cable, make cable in joint
Sealing reaches the degree of protection of IP68；To realize the maintenance for realizing old vehicle with minimum cost, significantly reduce because of cable
Electrical contact caused by the loosening of junction is bad.
Description of the drawings
Fig. 1 is the overall structure figure of the utility model.
In figure：1 cable, 2 pipe fittings, 3 external screw threads, 4 bellowss, 5 bands, 6 marks.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of four contact wiring harness structures, including cable 1, pipe fitting 2 and bellows 4, since pipe fitting 2 is
Component made of a kind of nylon, and the internal flute profile locking device for being equipped with locking cable 1, so as to meet dust-proof, waterproof, anti-
Shake, erosion-resisting requirement realize that the locking to cable acts on, and cable 1 is interspersed in pipe fitting 2, and pipe fitting 2 is provided at both ends with
External screw thread 3, external screw thread 3 and one end of bellows 4 match, and bellows 4 is set in outside cable 1 and is rotationally connected with pipe fitting 2
On；By the protection of bellows 4, cable 1 is avoided directly to be contacted with the external world, realizes the protection to cable；It is also bundled on bellows 4
There is band 5, mark 6 is installed on band 5, is convenient for the identification of people by mark 6.
This four contact wiring harness structure, since pipe fitting 2 is made of nylon, and both ends carry external screw thread, and there is flute profile lock in inside
Tight device, you can realize the docking of bellows 4 and connector, while can realize that the locking to cable 1 acts on, cable 1 is made to connect
Sealing at head reaches the degree of protection of IP68；To realize the maintenance for realizing old vehicle with minimum cost, significantly reduce
The electrical contact because caused by being loosened at cable connection is bad.
In summary：This four contact wiring harness structure is realized the maintenance of old vehicle with minimum cost, significantly reduced because of electricity
Cable junction loosen caused by electrical contact it is bad, thus effective solution the problems of the prior art.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
