Abstract

A novel electrical porcelain insulator is composed of an insulator body and a lower insulator bolt, the top of the insulator body is equipped with a groove, and bolts are pre-buried at the two sides of the groove respectively. A segment of screw rod is exposed out of the upper end of each bolt, a pressure plate is equipped with an upwards protruded pressing groove of which the two sides are equipped with through holes matching the bolts respectively, and a layer of rubber pad is added under the pressure plate. The pressing and coverage of the utility model are large-area contact, so that the fixing mode has a smaller pressure than the fixing mode of binding via metal wires, and a conducting wire is not easy to fold and damage.

Description

A kind of novel electric power porcelain vase

Technical field

The utility model is a kind of power equipment, i.e. a kind of novel electric power porcelain vase.

Background technology

On distribution line, all to fix wire with electric power porcelain vase.The much more fixing strappings that adopt of existing porcelain vase and wire, use metal wire conducting wire binding on porcelain vase.This mode has three large drawbacks, and the one, process of binding is more loaded down with trivial details.The 2nd, metal wire has certain injury to wire, easily causes wire to lose.The 3rd, to fix too deadly, the wire between two shaft towers forms an independently line segment, and the intrinsic frequency ratio that shakes is simpler, easily with the frequency of external vibration, is complementary and resonates, the losing of acceleration wire.

The utility model content

The purpose of this utility model is for a kind of novel electric power porcelain vase is provided, to solve the problem in background technology.

In order to achieve the above object, the utility model is realized by the following technical solutions:

A kind of novel electric power porcelain vase consists of bottle and following bottle bolt, have a groove at the bottle top, at two of groove, respectively to give and bury a bolt, one section screw rod is exposed in upper end, a pressing plate, the above is with the indent of an epirelief, and the both sides of indent, respectively have a through hole coordinated with bolt, in order to reduce the wire wearing and tearing, below pressing plate, can add one deck rubber blanket.

During use, first porcelain vase is contained on overhead line structures by the bottle bolt, then wire is placed on groove, the upper cover top board, wire is crushed on below indent, and two bolts are exposed at above pressing plate through through hole, then use nut screwing clamping, just wire have been fixed.In order to reduce the wearing and tearing of wire, there is the curling crimping that makes progress at indent two of pressing plate, and there is the said bolt in reclinate circle shoulder top at two of groove, can be also to have screwed hole on bottle, or give the nut that buries metal, and be attached thereto with bolt.

Beneficial effect:

The utility model gland is the large tracts of land contact, pressure than metal wire bundling is little, wire is difficult for losing, and this way of restraint allows wire that small twisting is arranged, and leads the performance of shaking good, phase mutual interference between each section lead, vibration frequency is complicated and changeable, and the system of environment strengthens in addition, and vibration state is more complicated, be difficult to produce resonance, thereby reduced the catastrophic failure of wire.

Visible in figure: bottle 1, bottle bolt 2, groove 3, pressing plate 4, wire 5, indent 6, bolt 7, crimping 8, circle shoulder 9, through hole 10, rubber blanket 11.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Shown in Fig. 3, Fig. 4, a kind of novel electric power porcelain vase consists of bottle 1 and following bottle bolt 2, has a groove 3 at the bottle top, at two of groove 3, respectively gives and buries a bolt 7 as shown in Figure 1, Figure 2, and one section screw rod is exposed in upper end.A pressing plate 4 is separately arranged, and the above is with the indent 6 of an epirelief, and the both sides of indent 6, respectively have a through hole coordinated with bolt 7.During use, first porcelain vase is contained on overhead line structures by the bottle bolt, then wire 5 is placed on groove 3, upper cover top board 4, wire is crushed on below indent 6, and two bolts 7 are exposed at above pressing plate through through hole 10, then use nut screwing clamping, just wire have been fixed.In order to reduce the wearing and tearing of wire, there is the curling crimping 8 that makes progress at indent 6 two of pressing plate, and there are the reclinate circle shoulder 90 said bolts 7 in top at two of groove, can be also to have screwed hole on bottle, or give the nut that buries metal, and be attached thereto with bolt.In order to reduce the wire wearing and tearing, below pressing plate, can add one deck rubber blanket 11.

Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and specification, describes just illustrates principle of the present utility model, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall in claimed the utility model scope, the claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. a novel electric power porcelain vase consists of bottle and following bottle bolt, it is characterized in that, have a groove at the bottle top, at two of groove, respectively give and bury a bolt, one section screw rod is exposed in upper end, a pressing plate, the above is with the indent of an epirelief, the both sides of indent, respectively have a through hole coordinated with bolt, add one deck rubber blanket below pressing plate.
