Description

Wiring terminal of plug-in circuit breaker

Technical Field

The utility model relates to an electrical equipment field, concretely relates to plug-in circuit breaker's binding post.

Background

The circuit breaker is for connecting circuit, generally all be provided with binding post and be connected with external conductor, traditional circuit breaker binding post is that the power direction of wiring operation is perpendicular with the wiring direction at present, the direction that external force was used for the wiring operation is not in same direction with the conductor wiring direction, lead to binding post wiring in-process to need the space of two directions at least to operate, but some circuit breakers need to install in narrow and small space at present, and only there is the space for the wiring operation in circuit breaker wiring direction, present binding post can't satisfy binding post wiring connection under this kind of condition.

When the existing spring piece type wiring terminal is used for connecting a conductor with a large current specification, the technical defect that the temperature rise of a circuit breaker is high due to the fact that only a single point is in contact with the conductor exists.

SUMMERY OF THE UTILITY MODEL

In order to overcome the deficiency of the background art, the utility model provides an increase area of contact, reduce the binding post of the bayonet circuit breaker of resistance.

The utility model discloses the technical scheme who adopts: the utility model provides a plug-in circuit breaker's binding post, its includes external conductor and the electrically conductive elastic component that supplies external conductor to peg graft, electrically conductive elastic component is the draw-in groove form, electrically conductive elastic component both sides wall is equipped with first contact board and second contact board, electrically conductive elastic component has when not inserting external conductor first contact board and second contact board have the first state of angular difference and insert the second state that first contact board and second contact board angular difference enlarge behind the external conductor.

The first contact plate and the second contact plate are integrally arranged, and the second contact plate is formed after the first contact plate is hollowed out.

The first contact plates on two sides are provided with bending parts which are opened outwards.

The second contact plate is located below the bending portion.

The processing track of the first contact plate hollow is J-shaped.

The utility model has the advantages that: according to the technical scheme, the two side walls of the conductive elastic element are processed, and the first contact plate, the second contact plate and the external conductor are connected in a multi-point mode, so that the contact area of electric connection is increased, and the contact resistance is reduced.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the wiring terminal of the plug-in circuit breaker comprises an external conductor 1 and a conductive elastic part 2 for the external conductor 1 to be plugged, wherein the conductive elastic part 2 is in a shape of a clamping groove, a first contact plate 3 and a second contact plate 4 are arranged on two side walls of the conductive elastic part 2, and the conductive elastic part 2 has a first state that the first contact plate 3 and the second contact plate 4 have an angle difference when the external conductor 1 is not plugged and a second state that the angle difference between the first contact plate 3 and the second contact plate 4 is enlarged after the external conductor 1 is plugged; according to the technical scheme, the two side walls of the conductive elastic element are processed, and the first contact plate, the second contact plate and the external conductor are connected in a multi-point mode, so that the contact area of electric connection is increased, and the contact resistance is reduced.

The first contact plate 3 and the second contact plate 4 are integrally arranged, the second contact plate 4 is formed by hollowing the first contact plate 3, and the hollow processing track of the first contact plate 3 is J-shaped.

The first contact plates 3 on both sides are provided with bending parts 5 which are opened outwards, the parts above the bending parts in the embodiment can play a guiding role, and external conductors can be inserted into the conductive elastic parts along the inner walls of the first contact plates.

The second contact plate 4 is located below the bending portion 5, and as shown in fig. 1, the second contact plate and the first contact plate have a connection point, and the connection point is located on the bending portion.

When opening electrically conductive elastic component manually, the portion of bending is close the horizontality after being propped open, and the second contact plate has the downward sloping of certain degree, can form an angle difference with between the first contact plate, and after inserting external conductor, the second contact plate will utilize this angle difference to keep laminating with external conductor's large tracts of land, has increased the area of contact of electricity connection, has reduced contact resistance.
