Specific implementation mode

It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained without creative efforts belong to The range of the utility model protection.

Embodiment：

A kind of microwave transmission twisting resistance acid bronze alloy CA cable assembly, the CA cable assembly include cable and the cable ends Two cable connection ends；As shown in Figure 2：The cable includes cable core 10 and the restrictive coating 20 that is wrapped in outside cable core 10, There are a fixed gaps between the cable core 10 and restrictive coating 20；This layer of gap is the electricity for facilitating cable while twisting Different degrees of rotation can occur when cable is by torsion for cable core 10 and restrictive coating 20, and torsion is uniformly disperseed It opens, prevents twisting from repeatedly 20 surface of the coat layer of power cable being caused to split.This layer of gap can also play the role of heat dissipation, In, cable core 10 from inside to outside successively include center conductor 11, dielectric 12 and inner insulating layer 13, inner insulating layer 13 by hardness compared with High high-density polyethylene material is made.Restrictive coating 20 includes external insulation layer 21, shielded layer 22 and rubber layer successively from inside to outside 23, external insulation layer 21 also uses the higher high-density polyethylene material of hardness and inner insulating layer 13 is opposite, polythene material sheet Body is smooth, may be implemented to slide relatively, and when cable is distorted, the gap among restrictive coating 20 and cable core 10 can To shrink, play the role of alleviating power.Shielded layer 22 is made of silver-plated copper band, can play the role of shielding.

As shown in Figure 1：The cable connection end includes nut 33, the end 32 of 33 axial direction of nut welding and weldering It is connected on the tail structure 30 of 32 other end of end；The end 32 and 30 inside of tail structure are in interconnected cylindrical empty Chamber is mounted with two rows annular the first sliding groove 34a and annular second sliding slot 34b, the first sliding groove 34a in the cylindrical cavity In the internal cavities of end 32, the second sliding slot 34b is mounted in the internal cavities of tail structure 30, and described first It is assembled with ball-type ball 31 in sliding slot 34a and second sliding slot 34b；The restrictive coating 20 passes through tail structure 30 and end 32, The restrictive coating 20 passes through the surface of part to be contacted with the spherical ball 31 in the first sliding groove 34a and second sliding slot 34b；It is described The endpoint of restrictive coating 20 forms lug boss 24 in outside annular projection, and the lug boss 24 can be stuck in the first sliding groove 34a In the gap formed with end 32, restrictive coating 20 is made to be connect with the cable connection end.Here cable and cable connection are realized End is connected, while the endpoint connected is using the structure of the first sliding groove 34a and second sliding slot 34b and ball-type ball 31 and electricity The restrictive coating 20 of cable connects, and the protrusion of ball-type ball just withstands restrictive coating 20, plays the role of support, and restrictive coating 20 can be Under the action of ball-type ball 31 and the first sliding groove 34a, second sliding slot 34b, 360 ° of arbitrarily rotations are realized, it thus can be in cable When by torsion, restrictive coating 20 is very easily dissolved torsion by the carriage in cable connector, prevents electricity Cable since it is desired that often rotation cause cable to bear excessive torsion, cause rubber layer 23 and the damage of shielded layer 22 in restrictive coating 20 Wound or deformation, to influence the normal use of microwave cable.It is provided with what outside annular projection was formed in the endpoint of restrictive coating 20 Lug boss 24, lug boss 24 can be stuck in the gap that the first sliding groove 34a is formed with end 32, make CA cable assembly on edge It and compares fixation in the horizontal direction of cable, will not arbitrarily slide on cable axial direction again.

The end 32 of 33 axial direction of nut welding is made of the material of metal or alloy, the tail structure 30 are made of the material of resin or rubber with toughness.The first sliding groove 34a is mounted on the internal cavities of end 32 simultaneously In, the second sliding slot 34b is mounted in the internal cavities of tail structure 30, and end 32 belongs to the firmer material of quality, can So that cable is more fastened in cable connection end, and tail structure 30 is then the relatively soft rubber or resin of quality, Ke Yi Recoverable deformation occurs in the case of to a certain degree, makes cable when bending, under the action of tail structure 30, protects very well Cable and cable connection end endpoint have been protected, has been damaged caused by so that it is not received bending,

The cable core 10 continue at the endpoint of the restrictive coating 20 it is axially extending, pass through the nut.
