Embodiment 1

[0041] The switching structure of this embodiment, such as figure 1 - image 3 As shown, it includes a moving part 1, a contact group, an actuating part and a driving mechanism.

[0042] The moving part 1 is driven to reciprocate by the driving mechanism, and two first abutting parts 12 are arranged on the side of the moving direction, and the abutting wall 11 of any one of the first abutting parts 12 is connected to the moving part 1. The distances of the moving lines are not completely equal, and the moving line in this embodiment is a straight line passing through the center of gravity of the moving part 1 and parallel to the moving direction of the moving part 1 . The two first abutting parts 12 are respectively located on opposite sides of the moving direction of the moving part 1. In this embodiment, the first abutting parts 12 are two arc-shaped grooves 13 arranged in opposite directions. That is, the first abutting portion 12 is S-shaped along the moving direction of...

Embodiment 2

[0050] Such as Figure 4 -6, the difference between this embodiment and Embodiment 1 is that the shape of the first abutting portion 12 is different, and the first abutting portion 12 in this embodiment includes a connecting portion, and is connected The disconnecting part of the two abutting parts, the connecting part and the disconnecting part of the two abutting parts are arranged in reverse order, the connecting part is the first connecting position, the connecting part and the disconnecting part The junction of the openings is the second connected position. The connection part is a straight line part 14 parallel to the moving direction, and the disconnection part is an arc part 15 protruding away from the moving part 1 .

[0051] When the moving part 1 reciprocates, it has a first switching position for connecting any one of the contact groups, and a second switching position for simultaneously connecting two groups of the contact groups; the moving part 1 is in the In ...

Embodiment 3

[0055] The difference between this embodiment and Embodiment 1 is that the shape of the first abutting portion 12 is different. The first abutting portion 12 in this embodiment includes two arc-shaped grooves 13 arranged in opposite directions, and two arc-shaped grooves 13 connecting the two. The connecting portion of the arc-shaped groove, the connecting portion has a set distance, the inner and outer walls of the two arc-shaped grooves (13) are the first connected position, and the connected portion is the first disconnected position .

[0056] refer to figure 1 - image 3 , when the switching structure of this embodiment is in use, the moving part 1 is located at the first on position on the upper side, at this time, the contact group on the right is in the on state, and the left contact group is in the off state; 1 moves upward under force, and when the rolling member 53 on the actuating member moves along the abutting wall 11 to the connecting part, because the distanc...

Abstract

The invention relates to the technical field of change-over switches, in particular to a switching structure and a change-over switching electric appliance. The switching structure comprises a movingpart which is driven by a driving mechanism to reciprocate, wherein at least one first abutting part is arranged on the side face of the moving direction of the moving part, and the distances betweenthe abutting walls of the first abutting parts and the moving line of the moving part are not equal. The switching structure also comprises at least two groups of contact groups which are arranged andcomprise fixed contacts connected with corresponding external connection pieces and moving contacts arranged corresponding to the fixed contacts; a triggering part which is arranged corresponding tothe moving part, wherein the triggering part is provide with a moving contact, the second abutting part of the triggering part can abut against the abutting wall, a bias pressing piece is arranged atthe side, away from the second abutting part, of the triggering part, and the bias pressing piece provides a bias pressing force for the triggering part towards the moving part. When the moving part moves, the second abutting part moves along the abutting wall, the first abutting part pushes the triggering part to move in the direction away from the moving part, the bias pressing part pushes the trigger part to move towards the moving part; and when the trigger part moves towards or away from the moving part, the moving contact and the static contact are connected or disconnected.

Description

technical field [0001] The invention relates to the technical field of transfer switches, in particular to a switching structure and a transfer switch appliance. Background technique [0002] A transfer switch is an electrical device that converts one or several load circuits from one power source to another. To complete the conversion between two power supplies, the transfer switch generally has two sets of static contacts connected to two different power inputs, and a set of moving contacts (or two sets of moving contacts combined into one) connected to the power output . [0003] Existing switch electrical appliances can be divided into two types from the structure of the switch movable contact: single-acting contact and double-acting contact. Driven by one driving mechanism, the single-moving contact reciprocates between two sets of static contacts to complete the power conversion function; the double-moving contact is driven by two driving mechanisms (or twice driven ...
