Description

An anti-loose wedge-shaped jumper clamp and its use method

technical field

The invention relates to an anti-loosening wedge-shaped wire jumper clamp and a method for using the same, belonging 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.

Contents of the invention

The object of the present invention is to provide an anti-loosening wedge-shaped wire jumper clamp and its use method. By adopting a clamp body with a closed structure to meet the requirements for the connection of large-section wires, the wire hole for clamping wires and the supporting fastening device are used to secure the wires. Continuing, the structure is simple, only need to use a wrench to realize quick installation, the wire holding force is strong, 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 present invention is: an anti-loosening wedge-shaped wire jumper clamp, which includes a clamp body, a wedge block and an anti-loosening bolt. There is an oblong bolt guide hole in the middle of the load-bearing seat along the length of the body, and two threading holes are provided on both sides. The wedge-shaped block is a wedge-shaped structure with a small front and a large rear. There is an arc-shaped slot, 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. Pass through the bolt guide hole, the screw hole through the spring washer, and fasten with the flat washer in turn.

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.

Lock bolts are commercially available.

A method for using an anti-loosening wedge-shaped jumper clamp, comprising the following steps:

When connecting jumper wires, first put the two jumper wire ends into the clamp body and into the wedge block, then pass the anti-loosening bolt through the bolt guide hole on the bearing seat of the wire clamp body and the screw hole on the wedge block Connected, by tightening the anti-loosening bolts, the wedge-shaped block moves upward, so that the wire is clamped in the wire groove formed between the clamp body and the wedge-shaped block; the reticulated grooves on the wedge-shaped block increase the holding force of the wire, and the anti-loosening bolt prevents wedge The block will become loose with the change of environment; when disassembling, loosen the anti-loosening bolt to realize the quick separation of the clamp body and the wedge block.

The beneficial effect of the present invention is that: the wire is clamped in the wire slot formed between the wire clamp body and the wedge block, and quick installation can be realized only by using an ordinary wrench, ring wrench or socket wrench without using special tools; The oblong bolt guide hole on the bearing seat of the clamp body is convenient for adjusting the position of the anti-loosening bolt, so as to adapt to the jumper connection of different cross-sections; the mesh-like concave pattern on the wedge block can increase the holding force of the wire; Loosening occurs with environmental changes; easy to disassemble, only need to loosen the anti-loosening bolts to realize quick separation of the clamp body and the wedge block; the closed structure of the clamp body can meet the requirements for connecting large cross-section wires.

detailed description

The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

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.
