Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example one

Referring to fig. 2 and 3, the locking band 5 is installed inside the terminal of the circuit breaker, the locking band 5 may be an elastic plate as a whole, and the function of conducting electricity is accomplished by fixing the conductive flap 6. In carrying out the wire head installation of pegging graft, locking screw 7 screws, locking hoop 5 constantly rises, wire head and the 6 extrusion contact of fixed electrically conductive folded plate, locking screw 7 screws hard when continuing, locking hoop 5 receives spacing bellied spacing of spacing breach 508 and locking chamber 4 inside walls, locking hoop 5 can't continue to rise, the limit hypoplastron 505 of locking hoop 5 receives the high pressure effect and takes place micro elastic deformation, the great pressure that produces the wire head under the buffering high pressure effect, avoid the mechanical irreversible deformation of wire head.

Example two

Referring to fig. 2 and 3, when the locking band 5 is at the lowest position, the locking screw 7 has been screwed to the lowest point, and a gap, i.e., a bottom surrounding gap 8, remains between the bottom side plate 501 of the locking band 5 and the circuit breaker housing 1. Therefore, when the locking screw 7 is screwed down to lock the locking hoop 5, the locking hoop 5 and the circuit breaker are not extruded, and the locking hoop 5 is protected.

The reason for the edge-surrounding gap 9 between the locking band 5 and the circuit breaker housing 1 is that when the locking screw 7 is screwed, the gap between the edge lower plate 505 and the edge upper plate 507 is increased, the edge lower plate 507 and the edge lower plate 505 are inclined outwards to a certain extent, and the edge-surrounding gap 9 can prevent the slightly inclined edge upper plate 507 and the edge lower plate 505 from rubbing against the circuit breaker housing 1.

EXAMPLE III

When some electricians violate rules or carelessly plug the thin wire in the wiring port 2 of the circuit breaker, the locking hoop 5 is constantly rising, when the upper limit notch 508 of the locking hoop 5 reaches the limit projection of the inner side wall of the locking cavity 4, the space between the bottom side plate 501 of the locking hoop 5 and the fixed conductive folded plate 6 is enough to firmly fix the electric wire head meeting the standard, but some thin wires cannot be fixed, the thin wire is prevented from being used by the circuit breaker with large specification, and the line safety accident rate caused by non-circuit breaker faults is reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
