Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a relay assembly base. Background Art

[0002] The relay assembly base, also known as the relay base, is an auxiliary component of the relay, which is mainly used to fix the relay and provide electrical connection. The design of the base helps the relay to be firmly installed on the panel and ensures that the connection between the relay contacts and the circuit is stable and reliable, thereby ensuring that the relay can work normally;

[0003] When the relay assembly base is in use, the relay is usually docked with the conductive device of the relay assembly base. After the docking is completed, the relay and the relay assembly base are installed and docked by fastening screws to achieve the limit fixation of the relay. After that, the plug-in terminal is connected to the external wire, and the contact of the relay is connected to the control signal circuit through the conductive seat and the terminal block, so as to complete the electrical connection;

[0004] During the use of the existing relay assembly base, although the relay can be limited and fixed by tightening screws, it is troublesome to disassemble and replace the relay later, which reduces work efficiency. Some relay assembly bases use adjustment equipment to drive the clamping plate to move, and finally use the clamping plate to limit and fix the relay. Although this method improves work efficiency, after the adjustment equipment adjusts the position of the clamping plate, it is often necessary to set an additional self-locking component to lock and fix the clamping plate, which is cumbersome to operate. For this reason, we propose a relay assembly base. Utility Model Content

The position of the limit plate can be adjusted by cooperating with the adjusting rod and the connecting plate, and finally the limit plate is used to limit and fix the relay, replacing the traditional method of limiting and fixing the relay by connecting with a bolt body. The operation is simple, and after the position of the limit plate is adjusted, it can also be self-locked by the screw rod structure, thereby improving work efficiency and effectively solving the problems in the background technology.

The operation is simple, and after the position of the limit plate is adjusted, it can also be self-locked through the screw structure, thereby improving work efficiency.
