Description

A kind of detachable cable fixing device

Technical field

The present invention relates to a kind of cable fixture, belong to the cable installing area.

Background technique

When cable need be fixed on than use in the long pipeline, the early stage scheme that adopts was, cable directly passes pipeline and clamps at the pipe ends mouth, and this fixation method damages cable and lead easily under the bigger situation of vibration, acceleration.For addressing this problem method commonly used at present is to be bent into round bullet circle with elastic metallic material, does a wire clamp clamping cables in the circle, and the precompression eyelet is extremely less than caliber.It recovers deformation to put it in the long tube relief, through the elastic compression tube wall, thereby reaches the purpose of attached cable.This mode simple installation, but be disposable use, on-dismountable, make cable maintenance relatively more difficult.

Summary of the invention

The objective of the invention is provides a kind of cable fixture that can fix and dismantle fast to the problems referred to above.

Detachable cable fixing device according to the invention; Comprise the expansion component, backguy component, locking component and metallic coil, said expansion component is uniformly distributed with and is sleeved on the cable; The backguy component passes the backguy hole that the component that respectively expands on the cable is uniformly distributed with; Be fixed in the cable two ends through the locking component, metallic coil is sleeved on outside the steel wire of the backguy component between the component of expanding in twos, and leaves the gap between the expansion component at two ends.

Said expansion component is made up of rubber ring and catch; Rubber ring is provided with the backguy hole of the center hole and the circumference uniform distribution of suit cable; Catch is a semi-circular structure, is provided with center hole corresponding with rubber ring and backguy hole, and two one group of symmetries are stuck in and place the rubber ring both ends of the surface on the cable.

Said backguy component is made up of steel wire and clamping sleeve, and clamping sleeve is connected the two ends of steel wire.

Said locking component is made up of locking catch and lock screw; Said locking catch be with the expansion component in the corresponding semi-circular structure of catch; Be provided with center hole and the tapped hole corresponding with the backguy module position; Two one group of symmetries are installed in the cable two ends, through lock screw backguy two ends and locking catch are fixed.

Advantage of the present invention has: 1, number of spare parts is few, and is simple in structure, and simple installation can be fixed on cable in the long pipeline easily; 2, cable and pipeline can clamp through same group of rubber parts, and the effective attenuation outside applies the magnitude of vibration, improve the vibration resistance of cable; 3, cable is fixed on the pipeline medial axis, has avoided the collision of wire harness and tube wall to sustain damage, and improves the functional reliability of cable.4, cable of the present invention fixedly critical component adopt rubber material, good springiness, deformation is big, frictional force is strong, can better tolerate various extreme environments.

Embodiment

Embodiment is elaborated to the present invention below in conjunction with accompanying drawing:

As shown in the figure, detachable cable fixing device according to the invention comprises the expansion component; Backguy component, locking component and metallic coil 4; Said expansion component is uniformly distributed with and is sleeved on the cable, and the backguy component passes the backguy hole that the component that respectively expands on the cable is uniformly distributed with, and is fixed in the cable two ends through the locking component; Metallic coil is sleeved on outside the steel wire of the backguy component between the component of expanding in twos, and leaves the gap between the expansion component at two ends.Wherein rubber ring 1, and catch 2 is formed the expansion component; Steel wire 5 is formed the backguy component with clamping sleeve 6; Lock screw 7, locking catch 3 is formed the locking component; Rubber ring 1 is a crucial retaining element of the present invention, and its material has high elasticity, oil resistant, characteristic such as low temperature resistant, and the main aperture in the middle of the rubber ring is slightly larger than cable size, can easier be enclosed within on the cable; If there has been connector two terminations of cable, then can major bore be cut a mouth, then it is stuck on the cable.4 pores of periphery can pass steel wire.When rubber ring receives the catch extruding, will radially be out of shape, expand to internal diameter and external diameter direction, can simultaneously cable and pipeline be fixedly clamped thus; Catch 2 is designed to semicircle, above perforate can pass steel wire.During use, two one group is stuck on the cable with rubber ring, transmits the pressure from metallic coil, and the distortion of extruding rubber ring.Steel wire 5 is used wire rope for the multicore aviation.Its predominant use is delivered to catch again for transmitting pressure to metallic coil through tension, pushes rubber ring at last, forces its dilatancy.Clamping sleeve 6 is crimped on the end of steel wire, is used to limit the steel wire position, and the pulling force that transmits steel wire is converted into the pressure to metallic coil.Lock screw 7 is a hollow structure, can pass the backguy component; Outside screw can cooperate with the locking catch; The termination perforate is bigger, can block backguy component termination clamping sleeve; Terminal fluting can be locked with screw-driver.Through the tension of rotation can regulate backguy component, and then the distortion of extrusion expansion component is expanded.

Locking catch 3 outward appearances are identical with catch 2, and the aperture that the main distinction is opened above being is through tapping, be used for the tension with lock screw fit adjustment backguy component, and then adjustment expansion component receive to squeeze the degree of distortion.

Metallic coil 4 is formed by the resilient metal strip helically coiling, and itself can be crooked arbitrarily, but axially can not produce deformation again, is the structural member of long-range preferably transmission pressure therefore.

Use expansion cable fixture of the present invention in pipeline during attached cable, concrete installation process is following:

1) rubber ring is stuck in cable one end from incision site, and the semicircle catch of symmetry is installed at the rubber ring two ends;

2) lock screw is screwed in the locking catch fully, and insert in the above-mentioned rubber ring corresponding aperture;

3) compress with the end of clamping sleeve, then the steel wire the other end is passed above-mentioned lock screw and rubber ring and catch thereof steel wire.

4) at the total length direction of cable its after-expansion component is installed evenly, is continued remaining expansion component is worn through steel wire and metallic coil.

5) in the end the locking catch that has lock screw is installed in the end of an expansion component rubber ring.

6) tighten up steel wire, clamping sleeve is loaded onto in the end, cuts unnecessary steel wire.

7) with the metallic coil colligation on cable 8, and reserving enough activity surpluses near the position of expansion component.

8) cable fixture after will installing is sent in the pipeline 9 with cable.

9) simultaneously from pipe ends toward going out the rotational lock screw, make the steel wire tension; This moment, rubber ring was under pressure, the beginning dilatancy, when rubber ring fully with cable and pipeline fixing after, lock screw is promptly regulated and is put in place.Cable finally is fixed in the pipeline.

When cable fixture of the present invention was dismantled: rotate each lock screw inward from the pipeline both sides simultaneously, steel wire is loosened, the rubber ring pressure stress was eliminated, and returns to the original-shape when packing pipeline into.After the contact pressure of rubber ring and cable and pipeline was eliminated fully, cable just can be pulled out pipeline smoothly.
