Abstract

The invention relates to a device structure for fixing cables, comprising two fixing plates, two pull wire combination components and two wire clips, wherein the two fixing plates, the two pull wire combination components and the two wire clips are separately fixed on a clamping ring by wire clip disk head screws, fixing plate disk head screws and sunk screws. The clamping ring is manufactured into an opening circular ring shape, and a first pull wire combination component goes through jacks on a first fixing plate and a second fixing plate to furl the clamping ring into a circle, and the clamping ring is arranged in a long pipe, the first pull wire combination component is pulled out from the two fixing plates, the clamping ring is elastically stretched to tightly adhere to the inner wall of the long pipe to fix the wire bundle of the cable. The invention has simple structure and convenient use and is easy to put into the long pipe, positions in the pipe can be randomly regulated to avoid the wall impact of the wire bundle and the cable and the reliability of the cable is enhanced.

Description

A kind of device of attached cable

Technical field

The present invention relates to the cable technology field, relate in particular to the device of attached cable.

Background technology

Be placed on the cable that uses in the long tube, general at present the employing at the two ends of long tube clamps, and do not carry out any fixing method in the pipe long cable is fixed in the long tube; In the use of cable, especially under vibration, the bigger situation of acceleration, the cable that pipe is inner because length long and inner without any fixing, cable often and inside pipe wall bump, use in this state, the lead in the cable fractures easily.

Summary of the invention

The present invention seeks at cable above-mentioned shortcoming in use, designed the device of a kind of attached cable that uses at long tube, this device can be easy to cable is fixed in the long tube, increases the unfailing performance of cable.

Fixture of the present invention includes: fixed head, collar, backguy component, wire clamp, alignment pin, this device mainly is by screw collar and first, second fixed head to be fixed, by the hole on first, second fixed head, in the hole with the first backguy component insertion fixed head collar is blocked then; During use, the first backguy component is pulled out from fixed head, utilize the elastic force of collar itself, collar and long tube inwall are close to, utilize frictional force that collar is fastened on the long tube inwall, thereby reach the purpose of fastening cable.Advantage of the present invention has: 1, can be easy to cable is fixed in the long tube, avoid the collision of wire harness and cable, improve the reliability of cable.2, this structure tightens up core of a cable in the centre, avoids long cable the phenomenon of solid conductor tension in use to occur.3, simple in structure, can be fixed on long tube inside easily.4, the position in pipe is not limit, and can adjust arbitrarily according to the needs of oneself.

Embodiment

The present invention is described in further detail below in conjunction with accompanying drawing:

Concrete structure of the present invention comprises: fixed head 1, the first backguy component 2, plug together bar 2.1, fixed head pan head screw 3, second fixed head 4, the second backguy component 5, component locating piece 5.1, wire clamp 6, wire clamp pan head screw 7, first wire clamp 8, collar 9, sunk screw 10, alignment pin 11.

The material of collar 9 is chosen to be elastic metallic material and makes the open circles annular, and its structure as shown in Figure 2.Before the use, at first break the head of collar 9 into two with one's hands certain angle and heat-treat, make collar after Fig. 2 shape flicks, have certain elastic force, can make collar 9 be close to the long tube inwall.

1) alignment pin 11 is packed in the location hole of second fixed head 6; By pan head screw 3 first fixed head 1, second fixed head 4 are fixed with collar 9; Then core of a cable is fixed in the ply-yarn drill of first wire clamp 8 and second wire clamp, 6 compositions, ply-yarn drill is fixed on the collar 9, as shown in Figure 1 with sunk screw 10 by the hole on first wire clamp 8 and the collar 9 again.

2) before cable is put into long tube, draw into collar in a circle by first fixed head 1 with inserting hole on second fixed head 4 with the first backguy component 2, and the bar 2.1 that plugs together that inserts the first backguy component 2 is packed in the long tube into; After adjust the position for the treatment of cable, the bar 2.1 that plugs together of the first backguy component 2 is pulled out from the inserting hole of two fixed heads and (held the second backguy component 5 from the other end of long tube when pulling out, avoiding pullling core of a cable makes the cable stressed), the locating piece 5.1 in the second backguy component 5 plays the role of positioning when plugging together bar pulling out.Collar 9 opens naturally by self elastic force, utilizes the tension force of collar 9 to make the inwall of collar 9 outer walls and long tube be adjacent to, thereby reaches the effect of fixed beam.If cable uses in the bigger environment of external force, can also increase the frictional force between collar 9 and the long tube inwall at the auxiliary material of cover rubber tubing on collar 9 pipes, perhaps adopt the method that increases collar 9 quantity to make cable fixing more firm.
