Abstract

A 0.4kV puncture antiskid cluster insulated tension-resistant wire clamp is composed of a wire clamping seat 1, wire pressing blocks 2, a wedge 3, a draw ring 4, a supporting housing 5, screws 6, etc. The 0.4kV puncture antiskid cluster insulated tension-resistant wire clamp is characterized in that the wire clamping seat 1 and the wire pressing block 2 clamp an insulated lead 7; the wedge 3 is arranged between an upper set of wedges and a lower set of wedges, wherein the upper set of wedges and the lower set of wedges are symmetrical with each other; the supporting housing 5 is mounted outside the upper set of wedges and the lower set of wedges; the supporting housing is fixed through two screws 6; the draw ring 4 is connected with the wedge; the wire pressing arc surface of the wire clamping seat 1 is provided with a plurality of needles for increasing a friction force through engagement; the wedge 3 is wedge-shaped; the draw ring 4 is connected with the wedge 3; and the draw ring 4 draws the wedge 3 so that the wedge 3 tightly presses the wire pressing block 2. One wire clamp can simultaneously clamp a plurality of wires. The specific needles on the wire clamp settle a problem in peeling of an insulated wire.

Description

0.4kV punctures anti-skidding clustering insulation strain clamp

Technical field

The present invention, be applied to mesolow distribution line, mesolow insulated conductor is concentrated and is fixed on electric pole or support On, thus mesolow suspended insulated guide wire boundling at random is fixed, it is a kind of General Promotion power circuit equipment Renewal product.

Background technology

Electric power core-bunched strain clamp is the important component part of electricity distribution power circuit, and it not only directly has influence on electric power The safety of circuit operation, reliability, and affect the economy of distribution line operation, ring to a great extent Guarantor property, and the service life of whole circuit, so how to design and develop, can be used for the height of insulative distributing circuit Effect energy-saving and environmental protection, the electric power clustering insulation strain clamp of safety, are that of China's power grid construction is anxious to be resolved heavy Big problem.Specifically how easily not peeling just can reliably set up covered wire？How more automatically effectively to clamp Fixing wire？The problems such as on, be required for a kind of product of innovation come before replacing old continued to use for many years have scarce Sunken old product.

Original insulating tension clamp, because chucking power is limited, clamps insulated conductor, easily causes wire streamline core pulling Even cause the problem of circuit breaking, so many power departments require insulated conductor peeling must be arranged on insulated On wire clamp, considerably increase workload and the damage to wire of installation.In addition, original mesolow wire clamp Article one, circuit needs an insulating tension clamp, and circuit multi-thread then folder quantity is just many, forms the construction of line unsightly, Safety is low.One wire clamp of the present invention can clamp a plurality of circuit simultaneously, and on wire clamp, distinctive ratchet solves covered wire The problem of road peeling.

Content of the invention

The purpose of the present invention is it is simply that for adapting to the power grid construction that China develops, thoroughly change the kind of old-fashioned power equipment Kind of disadvantage, designs and develops out a kind of power distribution circuit, has to grip and hang and pulls and supports wire function 0.4kV punctures anti-skidding clustering insulation strain clamp.

The technical scheme is that such：

A kind of 0.4kV punctures anti-skidding clustering insulation strain clamp, by tension seat 1, wire pressing block 2, and voussoir 3, draw ring 4, Supporting shell 5, screw rod 6 etc. are constituted, and tension seat 1 and wire pressing block 2 clamp insulated conductor 7, two groups of line balls symmetrical above and below There is voussoir 3, equipped with supporting shell 5 outside two groups of tension seats 1 symmetrical above and below, supporting shell 5 is connected by two screw rods 6 between block 2 Fixing, together with draw ring 4 is connected as with voussoir 3.The line ball arc surface of tension seat 1 is provided with several and stings to hold increases friction The acupuncture 2.1 of power.Voussoir 3 is wedge shape, and draw ring 4 draws in voussoir 3 with draw ring 4 together with being connected as with voussoir 3, from And voussoir 3 compression wire pressing block 2 can be made.

Marginal data

Fig. 1, is one of structural representation of the present invention；

Fig. 2, is wire pressing block 2 schematic diagram of the present invention；

Specific embodiment with reference to the marginal data present invention.

Embodiment：

As shown in Figure 1, 2, a kind of 0.4kV punctures anti-skidding clustering insulation strain clamp, by tension seat 1, wire pressing block 2, Voussoir 3, draw ring 4, supporting shell 5, screw rod 6 etc. are constituted, and tension seat 1 and wire pressing block 2 clamp insulated conductor 7, on There is down voussoir 3, equipped with supporting shell 5 outside two groups of tension seats 1 symmetrical above and below, supporting shell 5 is led between symmetrical two groups of wire pressing blocks 2 Cross two screw rods 6 to be connected, together with draw ring 4 is connected as with voussoir 3.The line ball arc surface of tension seat 1 is provided with some Individual stinging holds the acupuncture 2.1 increasing frictional force.Voussoir 3 is wedge shape, and together with draw ring 4 is connected as with voussoir 3, draw ring 4 draws Entering voussoir 3, forcing voussoir 3 to be pressed on wire pressing block 2, line block 2 is thus compress wire.

One wire clamp can clamp a plurality of circuit simultaneously, and on wire clamp, distinctive ratchet solves asking of insulated circuit peeling Topic.
