Abstract
The utility model relates to an insulated strain clamp with a plastic shell. The insulated strain clamp comprises a clamp body, two plastic wedge blocks and a steel rope, wherein a sliding rail is formed in the outer surface of the clamp body; two stop flanges are arranged at the ends of the sliding rail; the clamp body forms an inner cavity; each plastic wedge block forms a semicircle groove body; the two plastic wedge blocks are matched with each other to form a wire accommodating groove which is formed by two semicircle groove bodies; the plastic wedge blocks are arranged in a cone shape, and the plastic wedge blocks and the inner cavity of the clamp body form a matchable and slidable connection part; the outer end faces of the plastic wedge blocks are provided with a sliding block; the sliding block and the sliding rail in the outer end face of the clamp body form a slidable connection part; and the steel rope penetrates through two symmetrical holes which are formed in the lower part of the clamp body and is connected with the clamp body. By the structure, the insulated strain clamp has high reliability, is energy-saving and environment-friendly and convenient to install.
Description
Technical field
The utility model relates to a kind of shell insulation strain clamp of moulding.
Background technology
In power circuit, often use strain clamp and fix aerial cable terminal or strain section two ends, play fixed strain.There is following problem in actual use in this strain clamp: 1, the trunking body degree of depth of this wire clamp main body is less than the lead radius; Make lead insufficient with contacting of wire clamp main body; The contact-making surface of wire clamp pressing plate and lead is also less; More than two kinds of reasons make the frictional force between wire clamp and the lead not enough, cause the slip of lead easily; 2, strain clamp adopts the malleable cast iron manufacturing usually, and this material belongs to ferrimagnet, in the transmission of electricity process, can form the magnetic hysteresis whirlpool and decrease, and energy consumption is bigger; 3, malleable cast iron will discharge a large amount of toxic and harmfuls and dust in air in the course of processing, and environmental issue is outstanding; Need divest insulating barrier when 4, lead is installed, install inconvenient.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and a kind of reliability height, energy-saving and environmental protection, the shell insulation strain clamp of moulding easy for installation are provided.
For realizing above-mentioned purpose; The utility model adopts a kind of shell insulation strain clamp of moulding, and comprises a wire clip body, two plastics voussoirs and a steel cable, and the outer surface of wire clamp main body forms a slide rail; The termination of said slide rail is provided with two defining flanges; Wire clip body forms an inner chamber, and each plastics voussoir all forms a semicircle cell body, and two plastics voussoirs cooperatively interact and constitute a trunking that is combined by two semicircle cell bodies; The plastics voussoir is set to taper and slidably is connected with the inner chamber formation of wire clip body is suitable; The outer face of plastics voussoir is provided with a slide block, and said slide block slidably is connected with the outer face slide rail formation of wire clip body, and steel cable is connected on the wire clip body through the hole of two symmetries of wire clip body below.
The utility model further is provided with again, and said slide block is set to the spider shape, and steel cable is fixedly connected through rivet after inserting the hole below the wire clip body.
The utility model further is provided with again, and said wire clip body, plastics voussoir and spider shape slide block all adopt the reinforced plastics manufacturing, and adopts the injection molding way one-shot forming.
In sum; The beneficial effect of the utility model is: all adopt the reinforced plastics manufacturing owing to mould wire clip body, plastics voussoir and the spider shape slide block of shell insulation strain clamp; Belong to nonmagnetic substance, in the electric energy transmitting process, do not produce the magnetic hysteresis whirlpool and decrease good energy-conserving effect; Insulation strain clamp wire clip body, plastics voussoir and plastic core all adopt the one-shot forming of injection moulding mode, and " three wastes " that production process produces are few, reduced environmental pollution effectively; Need not divest wire insulation during installation, make easy construction safety; The termination of slide rail is provided with two flanges, can effectively prevent the slippage of plastics voussoir, has alleviated the labour intensity of construction.

Embodiment
Shown in Fig. 1-4, the specific embodiment of the utility model is to mould shell insulation strain clamp, comprises a wire clip body 1, two plastics voussoirs 2 and steel cables 3; The outer surface of wire clamp main body 1 forms a slide rail 11, and the termination of said slide rail 11 is provided with two defining flanges 12, and wire clip body 1 forms an inner chamber; Each plastics voussoir 2 all forms 21, two plastics voussoirs 1 of a semicircle cell body and cooperatively interacts and constitute a trunking that is combined by two semicircle cell bodies 21, and plastics voussoir 2 is set to taper and constitutes with the inner chamber of wire clip body 1 suitablely slidably be connected; The outer face of plastics voussoir 2 is provided with a spider shape slide block 4, and said spider shape slide block 4 slidably is connected with outer face slide rail 11 formations of wire clip body 1, and steel cable 3 is connected on the wire clip body 1 with rivet 5 through the hole of two symmetries of wire clip body 1 below; Said wire clip body 1, plastics voussoir 2 all adopt the reinforced plastics manufacturing with spider shape slide block 4, and adopt the injection molding way one-shot forming, when mounted; Insulated conductor embeds in the trunking body in the plastics voussoir 2; Under lead deadweight effect, plastics voussoir 2 progressively slides to the tiny end of wire clip body 1 inner chamber, because the squeezing action of wire clip body 1 inner chamber; The pressure that lead bears is increasing; Chamfered edge has also increased coefficient of friction, and lead is embedded in the wire clip body 1 securely, has played the effect of fixing and tension; Owing to have a spider shape slide block 4 on the plastics voussoir 2; The slide rail 11 that this spider shape slide block 4 can press from both sides body 1 outer surface along the line slides, and there are two flanges 12 termination of slide rail, prevents 1 slippage of plastics voussoir thereby can stop the flange of plastics voussoir 2 to skid off wire clip body 1 inner chamber; All adopt the reinforced plastics manufacturing owing to mould wire clip body 1, plastics voussoir 2 and the spider shape slide block 4 of shell insulation strain clamp; Belong to nonmagnetic substance, in the electric energy transmitting process, do not produce the magnetic hysteresis whirlpool and decrease good energy-conserving effect; Insulation strain clamp wire clip body 1, plastics voussoir 2 and spider shape slide block 4 all adopt the one-shot forming of injection moulding mode, and " three wastes " that production process produces are few, reduced environmental pollution effectively; Need not divest wire insulation during installation, make easy construction safety; The termination of slide rail 11 is provided with two flanges 12, can effectively prevent 2 slippages of plastics voussoir, has alleviated the labour intensity of construction.
