Problems solved by technology

[0004] The protective sheath in the prior art is mainly aimed at the ordinary cable head, adopts a straight cylindrical structure, and has no special protective device for sharpening the cable head, and the protective sheath of the existing ordinary cable head is often made of stainless steel, which is hard in texture. Because sharpening the cable head is easy to cause damage to the cable head, in addition, the length of the straight protective sleeve is short, and it is easy to fall off when it is set on the cable head

Embodiment 1

[0024] figure 1 It is a schematic diagram of the structure when the sharpened cable head sheath is not installed, figure 2 is the cross-sectional view after installation, such as figure 1 with figure 2 As shown, the sharpened cable head sheath includes sleeve 1 and sleeve 2, the length of sleeve 1 is 6cm-10cm, and the length of sleeve 2 is 10cm-18cm;

[0025] The sleeve 1 is composed of a conical sleeve 11 and a protective sleeve 12, the conical sleeve 11 is in the shape of a conical cylinder, and the left end is sealed; the protective sleeve 12 is in the shape of a hollow cylinder, and its left end is connected to the right end of the conical sleeve 11 That is, the big head end; the outer wall of the right end of the protective cover 12 is provided with a ring-shaped first mounting plate 13, the first mounting plate 13 coincides with the axis and the center of circle of the protective cover 12, and the right end surface of the first mounting plate 13 is in line with the p...

Embodiment 2

[0032] Such as image 3 As shown, on the basis of Embodiment 1, in this embodiment, the inner wall of the sleeve 2 is also provided with a plurality of protrusions 22 to increase the friction between the sleeve 2 and the cable, and the sleeve 2 can be used without artificial force. It is not easy to slide on the cable under the circumstances, thereby further fixing the sheath 1 on the cable head more stably.

Embodiment 3

[0034] On the basis of Embodiment 1 or Embodiment 2, the outer wall of the left end of the sleeve 2 in this embodiment is provided with threads, so that the sleeve 2 can be screwed into the protective sleeve 12 .

[0035] In this embodiment, four threaded holes are respectively arranged on the first mounting plate 13 and the second mounting plate 21. In practical applications, the number of threaded holes can be increased or decreased as required, as long as the first mounting plate 13 and the second mounting plate can be Two mounting plates 21 are fixed by bolts.

[0036] In this embodiment, the flexible insulating layer 14 is insulating silicone rubber. In practical applications, it can also be made of other flexible materials, such as other adhesive films, to prevent the sharpened cable head from being trapped in the tapered sleeve 11 and the protective sleeve 23. be damaged.

Abstract

The invention discloses a sharpened cable head sheath which comprises a sheath head and a sleeve, wherein the sheath head consists of a tapered sheath head body and a protective sleeve; the protective sleeve is hollow and cylindrical, and the left end of the protective sleeve is connected with the big end of the tapered sheath head body; a first ring-shaped mounting plate is arranged on the outer wall of the right end of the protective sleeve; threaded holes I are formed in the first mounting plate; the left end of the sleeve penetrates into the protective sleeve; a second ring-shaped mounting plate is further arranged outside the sleeve; the second mounting plate is fixed on the outer wall of the middle part of the sleeve; threaded holes II corresponding to the threaded holes I in the first mounting plate in number and position are formed in the second mounting plate; a soft insulating layer is further arranged on the inner wall of each of the tapered sheath head body and the protective sleeve. A sharpened cable head can be better protected from being damaged, and the condition that the cable head scratches an operator is avoided; the sharpened cable head sheath can be stably fixed on the cable head, has low possibility of falling off, and has the advantages that the structure is simple and compact, the use is convenient, and the stability is good.

Description

technical field [0001] The invention relates to the field of supporting equipment for electric power construction, in particular to a sharpened cable head sheath. Background technique [0002] With the progress of urbanization, electric power construction has entered a stage of rapid development; the voltage level is getting higher and higher, the capacity of wires is getting bigger and bigger, and it has entered the ground from high altitudes, and the technical requirements are getting higher and higher. At present, the high-voltage cables produced in China have the problems of non-standard copper wire size and non-concentric insulation layer. In view of this situation, high-voltage cable sharpeners are generally used to sharpen the cables. [0003] Under normal circumstances, after the cable head is made, it should be connected to the equipment immediately, and it should not be placed randomly to prevent damage. However, in practical applications, there may be redundantly...
