The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of protection against rodents cable, including cable core and the oversheath being coated on outside cable core, cable core includes conductor and is coated on to lead Insulating layer outside body, the oversheath are provided with spine layer outside.

By using said program, the conductor in cable core plays the role of conductive and signal transmission, and insulating layer, which is coated on, leads Outside body, playing the role of insulation prevents electric leakage, and oversheath is coated on the outside of cable core, plays a protective role to cable, reduces Damage of the applied external force to cable extends the service life of cable, and spine layer is arranged on the outside of oversheath, is gnawed when there is mouse When eating cable, mouse is stopped gnawing, thus reduces mouse gnawing and damaging to cable by the thorn of spine layer.

Preferably, the spine layer is included along the fixed main pricker of oversheath outer wall, the needle point of main pricker is perpendicular to cable Axis is directed toward outside cable.

By using said program, the needle point of main pricker is directed toward perpendicular to cable axis outside cable, is gnawed when there is mouse During cable to spine layer, needle point thorn mouse, mouse can not continue to gnaw cable, thus reduce mouse gnawing and damaging to cable It is bad.

Preferably, the main pricker outer wall is connected with auxiliary pricker.

By using said program, auxiliary pricker reduces the gap between main pricker, has further increased the spine of spine layer Area further improves the effect for preventing mouse from gnawing.

Preferably, it is provided with shielded layer between the insulating layer and oversheath.

By using said program, shielding action is played in the setting of shielded layer, and the conduction and signal for improving inner conductor pass Defeated performance.

Preferably, the shielded layer is tinned copper wire braided material.

By using said program, tinned copper wire braided material can effectively prevent electric current and radially leak, and ensure using peace Entirely.

Preferably, it is provided with flame retardant coating between the shielded layer and oversheath.

By using said program, the setting of flame retardant coating improves the protective capability to cable core, reduces high temperature, burning feelings To the breakdown of cable under shape, the safety that cable uses is improved.

Preferably, the flame retardant coating is Ceramic silicon rubber.

By using said program, Ceramic silicon rubber have it is splendid prevent fires, be fire-retardant, low cigarette, the characteristics such as nontoxic, squeeze out Moulding process is simple, and residue is hard ceramic housing after burning, and hard shell is not molten in fire hazard environment and do not drip, and has Effect plays the role of protecting cable core.

Preferably, the insulating layer is vulcanization EP rubbers.

By using said program, vulcanization EP rubbers is not variable glutinous, is not easily broken, and stereoeffect is contained in inside, With higher elasticity, heat resistance, tensile strength, effectively play a protective role to conductor.

Preferably, the oversheath vulcanizes EP rubbers thermoplastic elastomer cable material layer to exempt from.

By using said program, exempt to vulcanize the wearability of EP rubbers thermoplastic elastomer cable material layer, electrical insulating property, Toughness, cold resistance, water proofing property and chemical stability are preferable, can effectively play the effect of protection cable, and exempt from the life of vulcanization Production. art is at low cost.

In conclusion the utility model has the advantages that：

1st, spine layer is set by the outer wall in oversheath, when mouse is gnawed to spine layer, by the thorn of spine layer, Stopping is gnawed, and thus reduces mouse gnawing and damaging to cable.
