Furthermore, a protective layer is fixedly connected to the outer portion of the insulating layer, and the protective layer is made of rubber.

Furthermore, a plurality of annular heat dissipation grooves are formed in the outer portion of the protection layer.

Furthermore, a plurality of circular through holes are formed in the annular heat dissipation groove.

Furthermore, the protective layer is provided with a spring strip at the round through hole.

Furthermore, a plurality of circular radiating grooves are formed in the outer portion of the protective layer.

The utility model has the beneficial effects that:

1. through setting up insulating skin, rubber granule, sinle silk, rubber strip, metal flexible cord and insulating layer, when there is the impact and acts on with outside insulating layer department in the outside, at first because there is certain rubber granule in the insulating layer inside, the sheathed wire can be according to external impact position deformation, offsets partly impact, and the combination of a plurality of metal flexible cord simultaneously can be when the convenient degree of assurance wire stripping, has improved the anti-fracture ability of device.

2. Through setting up the protective layer, annular radiating groove, circular through-hole and spring strip, when the protective layer was reachd in outside impact, the protective layer was because there is the preferential deformation of annular radiating groove, and the spring strip receives the oppression simultaneously and takes place deformation, has improved the elasticity of protective layer, has improved the buffer capacity of device crust simultaneously.

3. Through setting up circular radiating groove, when the device is in the use, the circular radiating groove of outside has increased the heat transfer area of device with the outside air to the heat dispersion of device has been improved.

Detailed Description

To further illustrate the technical means and effects of the present invention for achieving the intended purpose of the utility model, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1-2, a cracked sheath line of laminating type resistance, including insulating layer 1, insulating layer 1 is inside to have seted up a plurality of through-hole, insulating layer 1 is equipped with metal flexible wire 4 in through-hole department, insulating layer 1 is inside to be equipped with rubber strip 7, rubber strip 7 outside bonds has a plurality of insulating skin 3, and insulating skin 3 is inside to be equipped with sinle silk 6, be equipped with a plurality of rubber granule 5 between insulating layer 1 and the insulating skin 3, when there is impact and acts on with outside insulating layer 1 department in the outside, at first because there is certain rubber granule 5 inside insulating layer 1, the sheath line can be according to external impact position deformation, offset some impact, the combination of a plurality of metal flexible wire 4 simultaneously, can be when the convenient degree of guaranteeing the wire stripping, the fracture resistance of device has been improved.

Wherein, 1 outside bonding of insulating layer has protective layer 2, and protective layer 2's material is rubber, a plurality of annular radiating groove 8 has been seted up to protective layer 2 outside, protective layer 2 is equipped with the circular through-hole 9 of a plurality of in annular radiating groove 8 department, protective layer 2 is equipped with spring strip 10 in circular through-hole 9 department, when outside impact reachs protective layer 2, protective layer 2 is because the preferential deformation of existence of annular radiating groove 8, spring strip 10 receives the oppression and takes place deformation simultaneously, protective layer 2's elasticity has been improved, the buffer capacity of device crust has been improved simultaneously.
