Detailed Description

Referring to fig. 1-4, a circuit breaker wiring terminal subassembly, includes wiring base 1 and wire connection frame 2, and the internally mounted of wiring base 1 has wire connection frame 2, and the middle part right side of wire connection frame 2 installs pivot 4, and the outside slip of pivot 4 has cup jointed long wiring shell fragment 5, and the outside slip of long wiring shell fragment 5 has cup jointed short circuit shell fragment 6.

In this embodiment, wire frame 2 integrated into one piece directly taps on wire frame 2, the upper right side vertical direction of wire frame 2 is equipped with binding screw 3, binding screw 3 slides from top to bottom in the upper right side of wire frame 2 is vertical direction, screws up binding screw 3 downwards, and binding screw 3 moves down after contacting with short-circuit connection shell fragment 6, and at this moment short-circuit connection shell fragment 6 rotates around pivot 4, exerts pressure to the wire middle part, and long wiring shell fragment 5 of short-circuit connection shell fragment 6 below exerts pressure to the wire bottom, and two connection shell fragments exert pressure to the wire simultaneously for the wire is more reliable and more stable when the wiring.

In this embodiment, the right side of long wiring shell fragment 5 and short circuit connection shell fragment 6 all sets up the bottom at binding screw 3, the middle part of long wiring shell fragment 5 and short circuit connection shell fragment 6 all trompil is provided with hole 7, binding screw 3's tightening force is little, the arm of force of long wiring shell fragment 5 and short circuit connection shell fragment 6 rotation moment is short, make long wiring shell fragment 5 and short circuit connection shell fragment 6 can act on bigger wiring pressure in the wire, when connecing the small-specification wire, binding screw 3's tightening force increases, the arm of force of long wiring shell fragment 5 and short circuit connection shell fragment 6 rotation moment is elongated, under the reliable prerequisite of assurance wiring, make the shell fragment act on the wiring pressure of small-specification wire little, make the wire not destroyed.

In this embodiment, the right side below of wire connection frame 2 is connected with reset spring 8, the end all is provided with the couple about reset spring 8, the couple embedding setting of reset spring 8 one side is in the hole 7 of long wiring shell fragment 5 and short-circuit connection shell fragment 6, when demolising the wire, reset spring 8 restores to the original position through pulling long wiring shell fragment 5 and short-circuit connection shell fragment 6 for long wiring shell fragment 5 and short-circuit connection shell fragment 6 can not block on the wire, hinder the extraction of wire.

The function of simultaneously using the long wiring elastic sheet 5 and the short wiring elastic sheet 6 is to ensure that the wiring reliability range of the wiring system is increased, and compared with a single elastic sheet, the wiring system avoids the failure of the elastic sheet caused by overlarge stroke, and can ensure that a small-specification wire can be tightly connected while the wire is not damaged.

The working principle is as follows:

when wiring, the wiring screw 3 is screwed downwards to contact the short-wiring elastic sheet 6 and then drive the short-wiring elastic sheet to move clockwise, after the wiring elastic sheet contacts a wiring lead, the short-wiring elastic sheet 6 is blocked from moving, and at the moment, the short-wiring elastic sheet 6 starts to deform elastically and applies wiring pressure to the lead;

when the wire is disconnected, the wiring screw 3 is screwed upwards, at the moment, the short wiring elastic sheet 6 and the long wiring elastic sheet 5 drive the short wiring elastic sheet 6 and the long wiring elastic sheet 5 to move anticlockwise under the action of the reset tension spring 8, the upper right part of the short wiring elastic sheet is attached to the top of the wiring screw 3 and moves together with the screwing of the screw, and the wire can be disassembled after the space is reserved;

when a small-specification wire is connected, only the long wiring elastic sheet 5 of the wiring system contacts the wire and applies acting force to the wire, and when a large-specification wire is connected, the short wiring elastic sheet 6 and the long wiring elastic sheet 5 need to be simultaneously deformed to generate acting force.
