Embodiment Construction

[0006] In the figure, a single-groove wire clamp is mainly composed of a compression bolt 10 and a lower clamping block 20. The compression bolt 10 penetrates into the screw hole of the lower clamping block 20, and the lower clamping block is provided with a raised U-shaped The clamping groove 21 is also screwed with a block-shaped upper clamping block 30 that is provided with a U-shaped clamping groove 31 matching the lower clamping block 20 on the compression bolt 10 . When in use, it is only necessary to tighten the bolts so that the upper clamping block matches the lower clamping block and clamps the wire.

Abstract

The clamp comprises pressure bolt and lower fixture block. The pressure bolt passes through bolthole on the lower fixture block. Raised U typed clamping groove is set at the lower fixture block. A lumpy is revolved into the pressure bolt, and upper fixture block of U typed clamping groove is set at the pressure bolt to match the lower fixture block. The invention provides features of reasonable structure and smart design. Surface contact between the upper fixture block and conducting wire makes proper fastening so as to overcome disadvantages of reduced holding power caused by creep of wires in traditional clamp.

Description

Technical field: [0001] The invention relates to electric equipment, in particular to a wire clamp suitable for distribution lines. Background technique: [0002] At present, the clamps commonly used on power distribution lines have a small contact area between the cable clamp and the clamped wire, which may easily lead to creep of the wire and decrease the grip force. Invention content: [0003] The technical problem to be solved by the present invention is to provide a single-slot wire clip which can effectively overcome the above defects and has a large contact area with the wire. The technical solution adopted by the present invention to solve the technical problem is that a single-slot wire clamp is mainly composed of a pressing bolt and a lower clamping block, and the pressing bolt penetrates into the screw hole of the lower clamping block, and its characteristics are: A protruding U-shaped clamping groove is provided on the clamping block, and a block-shaped upper ...
