Abstract

An opening switch and a remote circuit breaker are provided. The opening switch includes a base, and an energy storage assembly and a lock catch assembly that are disposed on the base; the energy storage assembly is disposed on an inner wall of the base, one end of the lock catch assembly is hinged to the base, a lock catch protrusion is disposed on the lock catch assembly, and the lock catch protrusion includes a barrier wall; and when the barrier wall is configured to abut against an energy storage arm of the energy storage assembly, under an action force of the energy storage arm, the lock catch assembly has a rotation tendency, so that the energy storage assembly maintains an energy storage state.

First claim

What is claimed is:

1 . An opening switch comprising:
a base; an energy storage assembly; and a lock catch assembly disposed on the base; wherein one end of the lock catch assembly is hinged to the base, a lock catch protrusion is disposed on the lock catch assembly, and the lock catch protrusion comprises a barrier wall; wherein based on the barrier wall being configured to abut against an energy storage arm of the energy storage assembly, under an action force of the energy storage arm, the lock catch assembly has a rotation tendency, so that the energy storage assembly maintains an energy storage state, wherein the lock catch protrusion further comprises a transition wall, wherein the transition wall and the barrier wall are located on a same side of the lock catch protrusion, and upon abutting against the energy storage arm of the energy storage assembly, the transition wall is configured to provide the rotation tendency to enable the lock catch assembly to be away from the energy storage arm.

2 . The opening switch according to claim 1 , wherein an included angle between the transition wall and the barrier wall is an obtuse angle.

3 . The opening switch according to claim 1 , wherein the transition wall is connected to the barrier wall with an arc transition.

4 . The opening switch according to claim 1 , wherein the lock catch protrusion further comprises a guide inclined wall, wherein the guide inclined wall is located on a side of the lock catch protrusion opposite to the barrier wall, and is configured to guide the energy storage arm to abut against the barrier wall.

5 . The opening switch according to claim 1 , further comprising: a first elastic component, wherein one end of the first elastic component is connected to the lock catch assembly, an other end is connected to the base, and the first elastic component is configured to provide a tendency for the lock catch assembly to rotate toward the energy storage arm.

6 . The opening switch according to claim 1 , wherein the energy storage assembly comprises a rotating member that is rotatably connected to the base and a second elastic component that is connected to the rotating member; and
wherein the energy storage arm is located at one end of the second elastic component; and the rotating member is driven to rotate to enable the energy storage arm to abut against the barrier wall, so that the second elastic component is compressed, and the energy storage assembly is in the energy storage state.

7 . The opening switch according to claim 6 , wherein the rotating member comprises a rotating shaft that is rotatably connected to the base, and a turntable that is disposed on the rotating shaft; the second elastic component is a torsion spring, one end of the torsion spring abuts against the base, and an other end of the torsion spring abuts against the turntable; and the other end of the torsion spring is the energy storage arm of the energy storage assembly.

8 . A remote circuit breaker comprising an opening switch including:
a base; an energy storage assembly; and a lock catch assembly disposed on the base; wherein one end of the lock catch assembly is hinged to the base, a lock catch protrusion is disposed on the lock catch assembly, and the lock catch protrusion comprises a barrier wall; wherein based on the barrier wall being configured to abut against an energy storage arm of the energy storage assembly, under an action force of the energy storage arm, the lock catch assembly has a rotation tendency, so that the energy storage assembly maintains an energy storage state, wherein the lock catch protrusion further comprises a transition wall, wherein the transition wall and the barrier wall are located on a same side of the lock catch protrusion, and upon abutting against the energy storage arm of the energy storage assembly, the transition wall is configured to provide the rotation tendency to enable the lock catch assembly to be away from the energy storage arm.

9 . The remote circuit breaker according to claim 8 , further comprising: a release, wherein the release is disposed corresponding to an other end of the lock catch assembly in the opening switch; and the release drives the lock catch assembly to rotate along a hinged part, so that the energy storage arm in the opening switch is separated from the barrier wall.

10 . The remote circuit breaker according to claim 8 , wherein an included angle between the transition wall and the barrier wall is an obtuse angle.

11 . The remote circuit breaker according to claim 8 , wherein the transition wall is connected to the barrier wall with an arc transition.

12 . The remote circuit breaker according to claim 8 , wherein the lock catch protrusion further comprises a guide inclined wall, wherein the guide inclined wall is located on a side of the lock catch protrusion opposite to the barrier wall, and is configured to guide the energy storage arm to abut against the barrier wall.

13 . The remote circuit breaker according to claim 8 , wherein the opening switch further comprises: a first elastic component, wherein one end of the first elastic component is connected to the lock catch assembly, an other end is connected to the base, and the first elastic component is configured to provide a tendency for the lock catch assembly to rotate toward the energy storage arm.

14 . The remote circuit breaker according to claim 8 , wherein the energy storage assembly comprises a rotating member that is rotatably connected to the base and a second elastic component that is connected to the rotating member; and
wherein the energy storage arm is located at one end of the second elastic component; and the rotating member is driven to rotate to enable the energy storage arm to abut against the barrier wall, so that the second elastic component is compressed, and the energy storage assembly is in the energy storage state.

15 . The remote circuit breaker according to claim 14 , wherein the rotating member comprises a rotating shaft that is rotatably connected to the base, and a turntable that is disposed on the rotating shaft; the second elastic component is a torsion spring, one end of the torsion spring abuts against the base, and an other end of the torsion spring abuts against the turntable; and the other end of the torsion spring is the energy storage arm of the energy storage assembly.
