Abstract
Provided is a cable clamping apparatus for the secondary wire returning of a cable pole, comprising a set of hoop. The clamp clamping apparatus is special in that: the hoop is provided with four threading snap rings; the hoop comprises two hoop plates and a connecting bolt used for binding the two hoop plates together; the side surface of each hoop plate is respectively provided with four connected threading snap ring hoop plates; the threading snap ring hoop plates form a threading snap ring when the hoop plates are bound together; and the hoop plates and the four corresponding threading snap ring hoop plates are integrated. As the original threading snap ring is replaced by four threading snap rings, the cable for secondary wire returning is divided when passing through the threading snap rings, thereby having large heat radiation area and excellent heat dissipation. The cable clamping apparatus is capable of avoiding the leakage accidents resulting from accelerated aging of the insulating strip of the cable for secondary wire returning caused by overheating, and solves the problem that the cable for secondary wire returning is burnt out due to overheating.
Description
Technical field
The utility model relates to a kind of cable pole secondary and returns line and use cable fixture.
Background technology
Secondary return line with cable after air switch is drawn, need be connected with the link of cable pole top four-wire circuit.Because the difference in height between cable pole top and the air switch is big, it is big with the active force between the link of cable and four-wire circuit that secondary returns line, is prone to cause secondary to return line and comes off with cable.Therefore, need on cable pole, be provided for supporting secondary and return the jig of line with cable.Existing jig is by one group of anchor ear, and one places the threading snap ring on the anchor ear to form.Secondary returns line and has four with cable, and when passing the threading snap ring, four secondaries return line and flock together with cable, and weak heat-dissipating is prone to make secondary to return the insulated hull accelerated ageing of line with cable, causes secondary to return line and leaks electricity with the cable habitat.In case it is excessive with the electric current that cable passes through that secondary returns line, its habitat temperature is too high, can blow secondary and return line and use cable, causes power outage.
Summary of the invention
The technical problem that the utility model will solve provides a kind of good heat dissipation, can avoid secondary return line with cable leakage, delay insulated hull and wear out, prevent to blow secondary and return line and return line with the cable pole secondary of cable and use cable fixture.
The utility model is achieved in that
A kind of cable pole secondary returns line and uses cable fixture, comprises one group of anchor ear, and its special character is: on anchor ear, be provided with four threading snap rings.
Described anchor ear comprises two hoop plates and with two hoop plate obvolvents connecting bolt together, is respectively equipped with four continuous threading snap ring hoop plates in each hoop plate side that described threading chuck hoop plate forms the threading snap ring after the obvolvent of hoop plate.
Described hoop plate is an one with four corresponding threading snap ring hoop plates.
The beneficial effect of the utility model is:
Change an original threading snap ring into four threading snap rings, secondary returns line and is separated when passing the threading snap ring with cable, and area of dissipation is big, and thermal diffusivity is good.Avoided secondary to return line and accelerated the electric leakage accident that causes because of overheated aging speed, and secondary returns line and blown because of overheated quilt with cable with the insulating trip of cable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: anchor ear 1, hoop plate 101, threading snap ring 2, threading snap ring hoop plate 201, connecting bolt 3.
Embodiment
As shown in the figure; This cable pole secondary returns line and comprises one group of anchor ear 1 with cable fixture; Described anchor ear 1 is to constitute by two hoop plates 101 with two hoop plate 101 obvolvents connecting bolt 3 together; Be respectively equipped with four continuous threading snap ring hoop plates 201 in each hoop plate 101 side, described threading snap ring hoop plate 201 forms four threading snap rings 2 after 101 obvolvents of hoop plate.
During use, will bind round plate 101 and place the cable pole both sides, and four secondaries are returned line be through in advance between the threading snap ring hoop plate 201, and make anchor ear 1 chucking cable pole, threading snap ring 2 chucking secondaries return line and use cable with connecting bolt 3 with cable.
