Description

Technical Field

[0001] The utility model relates to the technical field of motor parts, in particular to a relay assembly suitable for a motor. Background Art

[0002] A relay is an electrical control device that, when the input (stimulus) changes to a specified level, causes a predetermined step change in the controlled variable in an electrical output circuit. It operates as an interactive relationship between a control system (also known as the input circuit) and a controlled system (also known as the output circuit). Commonly used in automated control circuits, it functions as an "automatic switch" that uses a small current to control a large current. Therefore, it plays roles in circuits such as automatic regulation, safety protection, and circuit switching. A relay is an electrical control device that, when applied to a specified input and held for a sufficient period of time, causes a predetermined step change in the controlled variable in the electrical output circuit. Once the input drops to a certain level and remains there for a sufficient period of time, it returns to its initial state. In the 18th century, scientists believed that electricity and magnetism were two completely unrelated physical phenomena. In 1820, Danish physicist Ørsted discovered the magnetic effect of electric current, and in 1831, British physicist Michael Faraday discovered electromagnetic induction. These discoveries confirmed that electrical energy and magnetic energy can be converted into each other, which laid the foundation for the later birth of electric motors and generators; mankind entered the electrical age because of these inventions.

[0003] The application number is CN201220520100.3, which discloses a solid-state relay, including a relay body, wherein the relay body has a plurality of wiring assemblies, the wiring assembly including an adjusting screw, a movable wiring terminal screwed with the adjusting screw, and an inner wire connecting piece, the movable wiring terminal having a hollow inner cavity, the inner wire connecting piece being arranged in the inner cavity of the corresponding movable wiring terminal, and the inner wire connecting piece being relatively fixed to the relay body, a wire clamping cavity being formed between the inner wire connecting piece and the movable wiring terminal, the side wall of the relay body being provided with an adjusting hole opposite to the head of the adjusting screw, the side wall of the relay body being provided with a wiring hole opposite to the wire clamping cavity, the wiring assembly drives the movable wiring terminal to move inward or outward by turning the adjusting screw, thereby tightening or loosening the power cord, and the operation of connecting the power cord of the utility model is very convenient.

[0004] Although the above-mentioned utility model includes an adjusting screw, a movable terminal screwed with the adjusting screw, and an inner wire connecting piece through a wiring assembly, the movable terminal has a hollow inner cavity, the inner wire connecting piece is arranged in the inner cavity of the corresponding movable terminal, and the inner wire connecting piece is relatively fixed to the relay body, and a wire clamping cavity is formed between the inner wire connecting piece and the movable terminal, the side wall of the relay body is provided with an adjusting hole opposite to the head of the adjusting screw, and the side wall of the relay body is provided with a wiring hole opposite to the wire clamping cavity, and further by turning the adjusting screw, the adjusting screw is moved inward or outward, thereby driving the movable terminal to move inward or outward to tighten or loosen the power cord. The utility model is very convenient to operate when connecting the power cord, but there is a disadvantage that the device can only achieve the effect of dust reduction by sprinkling water when in use, but has not yet solved the effect of dust removal.

[0005] Therefore, it is necessary to replace the connection structure in the device with the current connection component 1, which can make it more convenient to connect and disassemble. Through the setting of internal parts, it can be very convenient to connect, save time and effort. Utility Model Content
