Fig. 1-5 is please referred to, the utility model provides a kind of technical solution:

A kind of multicore encoded servo device private cable that can be resistant to bending, including fixed sleeves 1, in the circumference of fixed sleeves 1 Wall offers fixing groove 11 at two sides, and the outer circumferential walls of fixed sleeves 1 are equipped with ripple protrusion 10, fixed sleeves 1 Inside is also provided with multiple semi-circular holes 12, and elastic piece 13 is equipped in semi-circular hole 12, is set on the circumferential inner wall of fixed sleeves 1 There is the first rubber tube 2, is equipped with convex block 20, the inside of the first rubber tube 2 at two sides in the outer circumferential walls of the first rubber tube 2 Equipped with the second rubber tube 3, cushion chamber 22, the first rubber tube 2 and the second rubber are equipped between the first rubber tube 2 and the second rubber tube 3 The first arc groove 21 and the second arc groove 30, and the first arc groove 21 are offered on the side outer wall close to each other of sebific duct 3 respectively Spring 4 is equipped between the second arc groove 30, the circumferential inner wall of the second rubber tube 3 is equipped with waterproof layer 5, the second rubber tube 3 Inside is equipped with multiple cable cores 6.

In the present embodiment, convex block 20 is an integral molding structure with the first rubber tube 2, convenient for making convex block 20 and the first rubber tube What is connected between 2 is more firm, mating between convex block 20 and fixing groove 11, is convenient for fixed sleeves 1 from the first rubber tube 2 It is dismounted, after fixed sleeves 1 are lost, convenient for being replaced to it, is not needed to replace entire cable, reduce Cost.

Specifically, it is mating between elastic piece 13 and semi-circular hole 12, elastic piece 13 is inserted into semi-circular hole 12, When fixed sleeves 1 are bent, elastic piece 13 can be made to be bent, since the elastic force of elastic piece 13 acts on, can reduced outer The bending power that fixing sleeve 1 is subject to, to protect fixed sleeves 1 well.

Further, ripple protrusion 10 is an integral molding structure with fixed sleeves 1, makes ripple protrusion 10 and fixed sleeves 1 What is connected is more firm, and ripple protrusion 10 is convenient for folding and squeeze, so that the bend-resistance of fixed sleeves 1 can be improved.

In addition to this, it is embedded cooperation between the second arc groove 30 between spring 4 and the first arc groove 21, spring can be made 4 are stably fixed between the first arc groove 21 and the second arc groove 30, when bending occurs for the first rubber tube 2, will drive bullet 3 bending of spring 4 and the second rubber tube, by the restoring force of spring 4 can reduce the first rubber tube 2 and the second rubber tube 3 is subject to Bending power, and then internal cable core 6 can be protected.

It should be noted that being equipped with filled layer 7 between cable core 6 and waterproof layer 5, waterproof layer 5 is by pure C alkene polymer material Material is made, and has good waterproof effect, and filled layer 7 is made of polyvinyl chloride resin particle, has good buffering effect, Cable core 6 can be protected well, there is good oxygen barrier effect, there is good flame retardant effect.

The multicore encoded servo device private cable that can be resistant to bending of the present embodiment when in use, when right in encoded servo device It is limited due to playing inner space when cable is installed, it needs to carry out bending laying to cable, when cable is bent, meeting Make 1 stress bending of fixed sleeves, so that 13 stress bending of elastic piece, when stopping bending, elastic piece 13 is understood towards initial Position is restored, and so as to reduce the bending power that fixed sleeves 1 are subject to, when 1 stress bending of fixed sleeves, will drive the first rubber Pipe 2 and the second also stress bending of rubber tube 3, so that 4 stress of spring is bent, spring 4 itself can generate restoring force, to subtract Extruding of small second rubber tube 3 to cable core 6, protects cable core 6 well, prolongs its service life.
