[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] The utility model provides a technical solution, please refer to Figure 1-3 :

[0022] A twisted pair cable for mining includes a wire body 1, on which two elastic sleeves 6 are sleeved and arranged correspondingly, and two ends of the elastic sleeve 6 are respectively provided with an opening 8 and a second opening 9, and the opening 8 and the second opening 9 are connected with bolts 10 by threads, and a protective sleeve 3 is wound around the outside of the wire body 1, and a card slot 5 is formed on the protective sleeve 3, and a side rod 7 extending into the card slot 5 is fixed on the elastic sleeve 6, and a limiter for limiting the two elastic sleeves 6 is also provided on the wire body 1. Circular grooves 2 distributed equidistantly are formed on the surface of the wire body 1, and a rubber block 4 matching the circular groove 2 is protruded on the inner wall of the protective sleeve 3, and the rubber block 4 is bonded to the circular groove 2 by glue. The protective sleeve 3 is wound around the outside of the wire body 1 to protect the wire body 1. The elastic sleeve 6 is elastic and has an opening, and the opening can be opened by bending the two ends of the elastic sleeve 6, so that the elastic sleeve 6 can be sleeved on the wire body 1. An anti-slip rubber ring is protruded on the part where the elastic sleeve 6 fits the wire body 1. Therefore, not only can the anti-slip strength between the elastic sleeve 6 and the wire body 1 be increased, but the elastic sleeve 6 can also be prevented from pressing and damaging the wire body 1. Example

[0023] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limiter includes a support rod 11 above the bolt 10, one end of the support rod 11 is rotatably connected to a rotating sleeve 12, and a screw groove 13 is provided on the rotating sleeve 12 to be threadedly connected to the screw rod of the bolt 10, and the other end of the support rod 11 is provided with a sleeve groove 14 sleeved on the screw rod of another bolt 10. Under the action of the support rod 11, the distance between the two elastic sleeves 6 can always be kept constant, and the protective sleeve 3 between the two elastic sleeves 6 can also maintain its own fit with the wire body 1, so the protective sleeve 3 can stably protect the wire body 1, that is, the elastic sleeve 6 will not be squeezed and deformed even if it is subjected to external force.

[0024] In summary, the embodiment provides that glue is applied to the annular groove 2 and the glue block 4, and then the protective sleeve 3 can be wrapped around the part of the wire body 1 that needs additional protection. Under the action of the glue, the protective sleeve 3 is fitted and fixed to the wire body 1 to protect the wire body 1. Then, the two elastic sleeves 6 are respectively put on the wire body 1, and the elastic sleeves 6 are pushed to move so that the side rod 7 extends into the slot 5. Bolts 10 are used to be threadedly connected with the opening 1 8 and the opening 2 9, so that the elastic sleeve 6 is fixed on the wire body 1.

[0025] The screw groove 13 of the rotating sleeve 12 is connected to the screw rod of one of the bolts 10 through threads, and the sleeve groove 14 on the support rod 11 is sleeved on the screw rod of the other bolt 10 .
