Description
Technical Field
[0001] This utility model belongs to the field of electrical control technology, and in particular relates to a moving contact bridge mechanism and a contactor. Background Technology
[0002] In existing contactor structures, the action of auxiliary contacts is usually driven by the action of main contacts. By setting an integrated linkage structure on the main contact bridge, the main contact bridge can drive the auxiliary contacts to move when it is in operation. However, this linkage method requires the main contact bridge to be integrated with the pre-set auxiliary contact linkage structure during the manufacturing process. In use, it is limited by the integrated structure, resulting in poor flexibility and difficulty in adjusting according to actual conditions. Summary of the Invention
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0004] Therefore, the first aspect of this utility model is to provide a moving contact bridge mechanism.
[0005] The second aspect of this utility model is to provide a contactor.
[0006] In view of this, according to one aspect of the present invention, a moving contact bridge mechanism is proposed.
[0007] In this application, the push rod is connected and fixed to the main cable tray, and the main cable tray is connected to the auxiliary cable tray, so that the auxiliary cable tray and the main cable tray can move with the push rod to complete the closing and opening actions of the contactor. Furthermore, by setting a first mounting hole on the main cable tray and installing a first moving contact plate in the first mounting hole, the main cable tray can synchronously drive the first moving contact plate to move when driven by the push rod, completing the closing and opening actions of the moving contact and the stationary contact, connecting and disconnecting the controlled circuit, and limiting the moving contact structure through the mounting hole, improving the alignment accuracy when the contact is closed, ensuring the contact area of the contact, and improving the conductivity. A first elastic element is installed between the main cable tray and the first moving contact plate. Through the elastic force of the elastic element, the contact force when the contact structure is closed is increased, improving the contact stability while reducing the contact resistance, reducing power loss and contact heating, and improving the performance of the contactor.
[0008] Furthermore, the main cable tray includes a hook-and-loop fastener, and the secondary cable tray is connected to the hook-and-loop fastener via a hook-and-loop fastener.

[0010] In this technical solution, the linkage part of the sub-cable tray is connected to the main cable tray, enabling the main cable tray to drive the linkage part to move. The linkage part is then sequentially connected to a first connecting part, a second connecting part, and a reinforcing part, so that when the main cable tray drives the linkage part to move, it can further drive the first connecting part, the second connecting part, and the reinforcing part to move. Furthermore, the structural strength of the sub-cable tray is enhanced by providing the reinforcing part.
[0011] In any of the above technical solutions, the linkage part and the hook part are connected by a hook.

[0013] In any of the above technical solutions, the linkage, the first connecting part, the second connecting part, and the reinforcing part are an integral structure.
[0014] In this technical solution, by setting each part of the sub-bridge as an integrated structure, the manufacturing and assembly difficulty can be reduced, and the structural strength, operational stability and linkage efficiency can be improved.
[0015] In any of the above technical solutions, the push rod is a cylindrical structure. During operation, the push rod moves along its axis. The main cable tray and the auxiliary cable tray move in the same direction as the push rod under its influence.
[0016] In this technical solution, the push rod is cylindrical and moves along the axis of the push rod. Since the main cable tray and the auxiliary cable tray are connected to the push rod, when the push rod moves along the axis, the main cable tray and the auxiliary cable tray will also move in the same direction as the push rod under the drive of the push rod. Through this technical solution, the movement of each cable tray is realized.
[0017] In any of the above technical solutions, the top rod includes an iron core, a connecting rod, and a second elastic element; the connecting rod passes through the iron core and the second elastic element and is fixedly connected to the main cable frame, and the second elastic element is located between the iron core and the main cable frame.

[0019] In any of the above technical solutions, the first connecting part includes a second mounting hole, and the second moving contact plate is installed in the second mounting hole.
[0020] In this technical solution, by providing a second mounting hole on the first connection part and installing the second moving contact plate in the second mounting hole, the auxiliary bridge can synchronously drive the second moving contact plate to move when driven by the main bridge, completing the closing and opening actions of the moving contact and the stationary contact, connecting and disconnecting the controlled circuit, and limiting the second moving contact plate through the second mounting hole, thereby improving the alignment accuracy when the contact is closed, ensuring the contact area of the contact, and improving the conductivity.
[0021] In any of the above technical solutions, the second moving contact plate includes a fixed part, at least one elastic part, and at least one contact part.
[0022] In this technical solution, the second moving contact plate consists of a fixed part, at least one elastic part, and at least one contact part.

[0024] In this technical solution, by setting each part of the second moving contact plate as an integral structure, the manufacturing and assembly difficulty can be reduced, and the structural strength, action stability and linkage efficiency can be improved. Furthermore, by using a metal sheet structure, the structural complexity can be reduced, the manufacturing difficulty can be reduced, and the contact reset speed and working efficiency can be improved.

[0039] Specifically, the push rod is connected and fixed to the main cable tray, and the main cable tray is connected to the auxiliary cable tray, so that the auxiliary cable tray and the main cable tray can move with the push rod to complete the closing and opening actions of the contactor. Furthermore, by setting a first mounting hole on the main cable tray and installing a first moving contact plate in the first mounting hole, the main cable tray can synchronously drive the first moving contact plate to move when driven by the push rod, completing the closing and opening actions of the moving contact and the stationary contact, connecting and disconnecting the controlled circuit. The mounting hole limits the moving contact structure, improving the alignment accuracy when the contact is closed, ensuring the contact area, and improving conductivity. A first elastic element is installed between the main cable tray and the first moving contact plate.

Furthermore, the structural strength of the sub-cable tray is enhanced by providing the reinforcing part.
[0043] In one embodiment of this utility model, the linkage part and the hook part are connected by a hook.
