Abstract
The utility model discloses a high-strength conductor clamping device of a circuit breaker. The clamping device comprises screws and a bracket. The bracket is a square structure which is formed by bending strip steel, and the top is additionally provided with a press plate. A T-shaped wedge is arranged on the press plate. A T-shaped slot matched with the T-shaped wedge is arranged at one side of the bracket. The T-shaped wedge of the press plate is pressed into the T-shaped slot of the bracket by external force, and the top of the bracket and the press plate are tightly overlapped into a whole. The top of the bracket and the press plate are respectively provided with threads which are matched with the screws. When the screws are screwed into the threads of the top of the bracket by the operator, the conductor in the bracket can be tightly pressed, so that the normal operation and use of the circuit breaker can be ensured.
Description
Technical field:
The utility model relates to a kind of high strength circuit breaker lead clamping device, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology:
Traditional circuit breaker lead clamping device is made of screw 1 and support 2 two parts as shown in Figure 1, and support 2 is the square structure that a top of adopting the bending of band steel to form adds pressing plate 3, and its top is provided with screw thread 4, and pressing plate 3 is provided with screwed hole 4; Because the pressing plate 3 of this circuit breaker lead clamping device is the cantilever type setting, so in practice of construction, the workmen is screwed into screw 1 on the screw thread 4 of support 2 napexes, and when compressing lead in the support, the reaction force that is produced by lead can cause that pressing plate 3 upwarps distortion, and makes the screw thread 4 sliding teeth at top, cause the pretightning force of support inside conductor to descend, can't compress the lead in the support, cause the lead heating, influence the operate as normal and the use of circuit breaker.
Summary of the invention:
For overcoming above-mentioned shortcoming, the purpose of this utility model provide a kind of rational in infrastructure, use reliable, easily manufactured high strength circuit breaker lead clamping device.
A kind of high strength circuit breaker lead clamping device described in the utility model includes screw and support two parts, support is the square structure that a top of adopting the bending of band steel to form adds pressing plate, on pressing plate, be provided with a T shape wedge, in a side of support, be provided with a T-slot that matches with T shape wedge; T shape wedge on the pressing plate is pressed in the T-slot of support by external force, makes the top of support and pressing plate be superimposed as one tightly; On the top and pressing plate of support, be provided with the screw thread that matches with screw, like this, when the workmen is screwed into screw in the screw thread that props up top of the trellis, the lead in the support be can compress tightly, thereby the operate as normal and the use of circuit breaker guaranteed.

Embodiment:
A kind of high strength circuit breaker lead clamping device described in the utility model includes screw 1 and support 2 two parts, and support 2 is the square structure that a top of adopting the bending of band steel to form adds pressing plate 3; On pressing plate 3, be provided with a T shape wedge 5, in a side of support 2, be provided with a T-slot 6 that matches with T shape wedge 5; T shape wedge 5 on the pressing plate 3 is pressed in the T-slot 6 of support 2 by external force, makes the top of support and pressing plate 3 be superimposed as one tightly; On the top and pressing plate 3 of support, be provided with the screw thread 4 that matches with screw 1.
During installation, earlier lead 7 is placed in the support 2 of high strength circuit breaker lead clamping device, then screw 1 is screwed in the screw thread 4 of support 2 tops and pressing plate 3, lead 7 is pressed in the support 2 tightly; Because the utility model on the top and pressing plate 3 of support, is provided with the screw thread 4 that matches with screw 1, has increased the effective length of screw thread; Simultaneously, on pressing plate 3, be equipped with a T shape wedge structure, constituted one " bridge type " structure with the T-slot 6 of support 2 one sides, so can improve the pretightning force and the bearing capacity of screw effectively, make screw compress the interior lead of support tightly, thereby improved the normal security performance of using of circuit breaker greatly.
