Problems solved by technology

However, due to seasonal changes and changes in temperature difference between day and night during use, the wires often become loose after crimping.
At the same time, we also found that the protruding bottom of the hoop and the bottom surface of the body are prone to corona phenomenon; and when used with other products, because the opening of the suspension clamp is too large, when the suspension clamp is subjected to vertical tension, the bolt will directly bend and deform. question

Embodiment Construction

[0021] The invention is like Figure 1-6 As shown, it includes a cover plate 5, a body 1 with a U-shaped cross section, and a U-shaped hoop 2. The cover plate 5 is connected to the U-shaped groove of the body 1 by a pair of U-shaped bolts 3. The U-shape of the hoop 2 The mouth facing upward pocket is clamped in the middle of the body 1. The inner bottom surface of the body 1 is a wire passing groove 11, which is composed of three arcs, including a middle section and a symmetrical head and tail section. The middle section has a curvature radius The radius of curvature is larger than the symmetrical head and tail section; the surface of the middle section is provided with a number of serrations 111 protrusions.

[0022] The saw tooth 111 is a straight line perpendicular to the length direction of the body.

[0023] The serration 111 is a transverse arc; taking the center of the body as a reference, the serrations on both sides of the center of the body are symmetrical. Such as Fig...

Abstract

The invention provides a slip preventive suspension clamp which is connected reliably after being crimped and can avoid corona and device deformation. The suspension clamp comprises a cover plate, a clamp body with a U-shaped cross section and a U-shaped hoop, the cover plate is connected into a U-shaped groove of the clamp body via a pair of U-shaped bolts, an U-shaped opening of the hoop is upwardly clamped in the middle of the clamp body, the inner bottom side of the clamp body includes a wire through duct which is composed of three arc lines, namely a middle segment and symmetric head and tail segments, the curvature radius of the middle segment is greater than those of the symmetric head and tail segments, and the surface of the middle segment is provided with sawtooth projections. The middle large arc segment in the bottom of the boat-shaped clamp body is provided with transverse sawteeth, so that the grip of the suspension clamp for leads is ensured; and the bottom of the clamp body is provided with the groove, the hoop is embedded into the groove and is not protruded out of the surface, so that a corona phenomenon is avoided.

Description

Technical field [0001] The invention relates to the technical field of electric power fittings, in particular to a suspension clamp. Background technique [0002] The suspension clamp is produced by aluminum alloy material and casting process. The structure is an anti-corona bag type. The body of the suspension clamp is the hull. The middle part is equipped with a hoop for hooking and a cover plate for crimping, which can fix the wire In the cable trough of the boat-shaped body. However, during use, due to seasonal changes and changes in temperature between day and night, wires often become loose after crimping. At the same time, we also found that the protruding bottom of the hoop and the bottom surface of the body are prone to corona phenomenon; and when matched with other products, the opening of the suspension clamp is too large, causing the suspension clamp to be directly bent and deformed when the suspension clamp is subjected to vertical tension. problem.
