Detailed Description

As shown in fig. 1 to 3, the corrosion-resistant cable comprises a cable outer layer 1, an electric core 2 and a cable inner layer 3, wherein the cable inner layer and the cable outer layer are made of the same material, the inner wall of the cable outer layer is provided with a plurality of protrusions 5, the protrusions 5 are abutted to the cable inner layer to play a supporting effect, the electric core 2 is wrapped by the cable inner layer 3, a movable cavity is arranged in the cable inner layer 3, and a fluid substance is stored in the movable cavity; be equipped with in the bellying and aggravate the chamber, aggravate the intracavity and placed weight 7, the one end of weight 7 is passed the bellying and is extended to external environment, is equipped with cavity 712 in the weight, is equipped with the rolling block 711 in the cavity, is equipped with a plurality of first louvres 6 on the bellying, first louvre 6 with aggravate the chamber and switch on mutually.

Wherein, weight 7 is made for the metal, and the radiating effect is good, and weight 7 is fixed in the bellying through heat-conducting glue, is equipped with a connection channel on the bellying 5, and the one end of weight passes connection channel and extends to external environment, and this end is fan-shaped structure, has increased the windward side for the weight is at the exogenic action, and connection channel's diameter is less than the diameter of weight, makes weight 7 be difficult to through connection channel, and the weight firmly fixes on the cable is outer, and heat-conducting glue is with higher speed the heat dissipation of electric core.

Wherein, cable inlayer 3 is equipped with a plurality of second louvres (not shown in the drawing), and the second louvre does not switch on with the activity chamber mutually, and the one end and the electric core of second louvre switch on mutually for electric core heat dissipation, cable inlayer 3 is equipped with a plurality of spacing portions 312 towards one side of cable skin 1, and the bellying setting is between two adjacent spacing portions.

Wherein, the surface of the outer 1 of cable is equipped with many recesses 111, and the outer surface parcel one deck waterproof mantle 112 of cable, waterproof mantle pass through the waterproof glue to be fixed on the outer of cable, have promoted the waterproof nature of whole device, and the recess is covered to the waterproof mantle, and the recess is located between two adjacent weight blocks.
