Description

An anti-loosening wedge-shaped jumper clamp

technical field

The utility model relates to an anti-loosening wedge-shaped wire jumper clip, which belongs to the technical field of wire connection fittings for power transmission and distribution lines.

Background technique

At present, wedge-shaped clamps are widely used in power transmission and distribution lines for non-load-bearing connection of wire jumpers. Wedge-shaped clamps include C-shaped components and wedges. When installing, you need to use a special ejection gun to launch a special ejection core or use a special hydraulic clamp for installation. , The ejection core is a consumable, which will increase the installation cost, the price of special tools is high, and it is very inconvenient to operate when working at heights.

Wedge-shaped clamps generally do not have anti-loosening devices. During operation, the wedges will loosen with environmental changes, which will increase the contact resistance of the joints and cause electrical failures. Even with anti-loosening devices, the structure is more complicated, and wedge-shaped clamps are added. Production difficulty and production cost.

Wedge-shaped clamps generally adopt a C-shaped structure, and the strength is difficult to meet the requirements for connecting large-section wires.

Utility model content

The purpose of the utility model is to provide an anti-loosening wedge-shaped wire jumper clamp, which meets the requirements for connecting large-section wires by adopting a clamp body with a closed structure, and adopts wire holes for clamping wires and matching fastening devices for wire connection. Simple, fast installation can be realized by using a wrench, the wire has strong holding force, and the anti-loosening bolt can effectively prevent the wire clip from loosening, effectively solving the above-mentioned problems in the background technology.

The technical solution of the utility model is: an anti-loosening wedge-shaped wire jumper clamp, which includes a clamp body, a wedge block and an anti-loosening bolt. Force seat, the middle part of the force seat has an oblong bolt guide hole along the length direction of the body, and two threading holes are provided on both sides. There is an arc-shaped slot on the side, and the arc-shaped slot and the two side walls of the clamp body form a wire hole. The wire is clamped and set in the wire hole through the threading hole. The symmetrical axis of the wedge-shaped block has a long screw hole to prevent loosening The bolts pass through the bolt guide holes in turn, and the screw holes are fastened through spring washers and flat washers.

The arc-shaped groove is provided with mesh-like concave grooves.

The clamp body and the wedge block are made of high-strength aluminum alloy.

The beneficial effect of the utility model is: the wire is clamped in the wire groove formed between the wire clamp body and the wedge-shaped block, no special tools are needed, and only ordinary wrench, ring wrench or socket wrench can be used to realize quick installation; The oblong bolt guide hole on the bearing seat of the cable clamp body is convenient for adjusting the position of the anti-loosening bolt to adapt to the jumper connection of different cross-sections; the mesh-like concave pattern on the wedge-shaped block can increase the holding force of the wire; the anti-loosening bolt can effectively prevent the wedge The block becomes loose with the change of the environment; it is easy to disassemble, and the clamp body and the wedge block can be quickly separated only by loosening the anti-loosening bolt; the closed structure of the clamp body can meet the requirements for large-section wire connection.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

An anti-loosening wedge-shaped wire jumper clamp, comprising a clamp body 1, a wedge block 2 and an anti-loosening bolt 3, the clamp body 1 is a closed structure with a small front and a large rear, and a small end is provided with a bearing seat 11, There is an oblong bolt guide hole 13 in the middle of the bearing seat 11 along the length direction of the body, and two threading holes 12 are provided on both sides. There are arc-shaped wire slots 21 on the left and right sides. The arc-shaped wire slots 21 and the two side walls of the clamp body 1 form wire holes. The wires are clamped and arranged in the wire holes through the wire-through holes 12. Long screw hole 23, anti-loosening bolt 3 passes through bolt guide hole 13, screw hole 23 by spring washer 4, flat washer 5 fastening successively.

The arc-shaped slot 21 is provided with a mesh-shaped concave groove 22 .

The clamp body 1 and the wedge block 2 are made of high-strength aluminum alloy.

In practical application, when connecting the jumper wires, the two jumper wire ends are first inserted into the clamp body 1 and wedge-shaped block 2, and the anti-loosening bolts 3 are passed through the bolt guides on the bearing seat 11 of the wire clamp body 1. The hole 13 is connected with the screw hole 23 on the wedge block 2, and the wedge block 2 is moved upward by tightening the anti-loosening bolt 3, so that the wire is clamped in the wire groove formed between the clamp body 1 and the wedge block 2; the wedge block 2 can increase the holding force of the wire; the anti-loosening bolt 3 can effectively prevent the wedge block 2 from loosening as the environment changes; only need to loosen the anti-loosening bolt 3 to realize the clamp body 1 and the wedge-shaped Block 2 snaps apart.
