Problems solved by technology

Inevitably, when it encounters rain or snow, water will enter the special-shaped parallel groove clamp, which will affect the service life of the clamp on the one hand, and on the other hand, will easily lead to the connection of the wires in the clamp, causing the power transmission circuit to be damaged. failure
In the prior art, a waterproof cover is installed on the outside of the special-shaped parallel groove clamp. At the same time, it brings inconvenience to the installation and disassembly of the special-shaped parallel groove clamp. The design of the waterproof cover also leads to an increase in the production cost of the cable clamp.

Embodiment Construction

[0015] Such as figure 1 As shown, a special-shaped parallel groove clamp of this embodiment includes an upper pressing part 1 and a lower pressing part 2, and the upper pressing part 1 and the lower pressing part 2 are fixedly connected by bolts 5, and the inner part of the upper pressing part 1 The surface is provided with a concave arc-shaped wire groove, and the upper surface of the lower pressing part 2 is provided with an arc-shaped inner concave wire groove corresponding to the wire groove of the upper pressing part 1, and the two correspond to each other to form a wire clamp for accommodating wires Slot 3. The outer surface of the upper pressing part 1 intersects with the inner surface at the end to form a raised end 4, and the two ends of the lower pressing part 2 also form corresponding curved parts. The inner surface of the crotch of the pressing part 2 is attached to each other, that is, the two can move with each other, and the two are always kept in a sealed stat...

Abstract

The invention discloses a special-shaped parallel groove clamp. The special-shaped parallel groove clamp includes an upper pressing component and a lower pressing component; wire clamping grooves are arranged between the upper pressing component and the lower pressing component; the outer surface and the inner surface of the upper pressing component intersect with each other at tail ends, so that tilted ends can be formed; the tilted ends are bent inwards, so that inwards-bent hooks can be formed; the tilted ends are fittingly attached to the inner surface of the lower pressing component; and the inward-bending radian of the tilted ends is larger than 90 degrees. With the above technical scheme of the invention adopted, rain will not penetrate the wire clamping grooves. The special-shaped parallel groove clamp is of an integrally-molded structure, and therefore, mechanical strength can be ensured, and at the same time, sealing requirements can be satisfied.

Description

technical field [0001] The invention relates to the field of power lines, in particular to a special-shaped trench parallel clamp. Background technique [0002] In the connection of power wires, the ability to continuously conduct electricity between wires of different materials is usually used. Therefore, special-shaped parallel groove clamps came into being. In the power system, most of the components need to be installed outdoors, and the special-shaped parallel trench clamps are also exposed outdoors. Inevitably, when it encounters rain or snow, water will enter the special-shaped parallel groove clamp, which will affect the service life of the clamp on the one hand, and on the other hand, will easily lead to the connection of the wires in the clamp, causing the power transmission circuit to be damaged. failure. In the prior art, a waterproof cover is installed on the outside of the special-shaped parallel groove clamp, which brings inconvenience to the installation an...
