Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a cable with protection of shocking resistance, includes conductor 1, the outside cladding of conductor 1 has first insulating rubber cover 2, the outside integrated into one piece of first insulating rubber cover 2 has evenly distributed's connecting strip 6, the outside of connecting strip 6 bonds in the inboard of second insulating rubber cover 3, third insulating rubber cover 4 has been cup jointed in the outside of second insulating rubber cover 3, fourth insulating rubber cover 5 has been cup jointed in the outside of third insulating rubber cover 4, blind hole 10 has evenly been seted up in the outside of fourth insulating rubber cover 5, spliced pole 11 fixedly connected with cylinder 12 is passed through to the inboard of blind hole 10, be equipped with cavity 13 in the cylinder 12, one side of cylinder 12 is equipped with the bell mouth 14 that is linked together with cavity 13, the inboard bottom of blind hole 10 is equipped with in bell mouth 14 assorted stopper post 15.

In this embodiment, specifically: the outer side of the column body 12 is integrally formed with a conical protrusion 16, the outer side of the conical protrusion 16 is attached to the inner side wall of the blind hole 10, and the conical protrusion 16 is used for preventing dust from entering the blind hole 10.

In this embodiment, specifically: the blind holes 10 are uniformly distributed on the outer side of the fourth insulating rubber sleeve 5, so that the cable surface is provided with a plurality of cylinders 12, and the cable can be well protected.

In this embodiment, specifically: the inboard of third insulating rubber cover 4 evenly is equipped with the protruding strip 8 of second, V type groove 9 has been seted up to one side of the protruding strip 8 of second, the outside of second insulating rubber cover 3 evenly is equipped with the first protruding strip 7 that inserts in V type groove 9 for second insulating rubber cover 3 and third insulating rubber cover 4 can not rotate.

In this embodiment, specifically: one side of the blind hole 10 is provided with a groove 17, and the groove 17 can prevent the fourth insulating rubber sleeve 5 from being torn when the plug 15 moves.

According to the working principle or the structural principle, when the cable falls, the column body 12 firstly contacts the ground, and at the moment, when the impact force is not large, the column body 12 can buffer through the tension of the connecting column 11 and the deformation of the column body, so that a slight buffer effect is achieved, and the conductor 1 in the cable is protected; when the impact force is too large, the cylinder 12 is quickly inserted into the blind hole 10, and the plug 15 blocks the conical opening 14, so that the chamber 13 forms a closed space, the air in the chamber 13 is compressed, used for buffering the cable, meanwhile, the plug 15 pushes the third insulating rubber sleeve 4 to deform, the third insulating rubber sleeve 4 pushes the second convex strip 8 to extrude the second insulating rubber sleeve 3, the second convex strip 8 is driven by the first convex strip 7 to be inserted into the V-shaped groove 9 during the extrusion, so that the second projected strip 8 is separated, thereby increasing the contact area of the second projected strip 8 with the second insulating rubber sheath 3, impact force is dispersed, the second insulating rubber sleeve 3 pushes the connecting strip 6 to deform, energy absorption and buffering are carried out in the deformation process of the connecting strip 6, thereby achieving the protection effect on the conductor 1 and preventing the conductor 1 from being broken due to the impact force of falling.
