Description

Technical Field

[0001] The present invention relates to the technical field of relays, and particularly to a small bistable relay with a high-insulation process structure that can be realized. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is usually applied to an automated control circuit, playing roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] During the production and assembly process of a relay, the insulation process is a main process in the relay assembly, which can ensure that the assembled relay has an insulation function and guarantee the safety of the relay during use.

[0004] The existing Chinese patent application with the publication number CN118800623A discloses a relay, including a contact container, a static contact lead-out terminal, a fixing member, a movable member, a movable piece, and a first magnetic conductor. The contact container includes an insulating cover and a yoke iron plate. The insulating cover is connected to the side surface of the yoke iron plate, and the insulating cover and the yoke iron plate form a contact chamber; the insulating cover is provided with a first through hole, and the first through hole communicates with the contact chamber; the static contact lead-out terminal passes through the first through hole; the fixing member is arranged in the contact chamber and is fixedly connected to the yoke iron plate; the movable member is movably arranged in the contact chamber and includes a moving spring, and the moving spring is used to contact or separate from a pair of static contact lead-out terminals; the movable piece is movably connected to the fixing member; the first magnetic conductor is arranged in the contact chamber and is connected to the movable piece. The first magnetic conductor is arranged on the side of the moving spring facing the static contact lead-out terminal; in this invention, the fixing member is connected to the yoke iron plate. Since the fixing member is fixed relative to the yoke iron plate, the magnetic attraction force generated between the first magnetic conductor and the movable member is transferred to the yoke iron plate, so that there is no need for excessive coil holding force, thereby reducing the coil power consumption and the volume of the relay, and improving the short-circuit resistance.

[0005] However, the relay has the following defects in specific use: 1. With the increasing competition in the relay industry, the economy of thrift has become the first element for the survival and development of enterprises. Therefore, high-energy-consuming products can no longer meet the modern production requirements. The current power relays need to be continuously powered on to maintain the closed state, with high energy consumption, resulting in a large temperature rise, which is likely to affect the service life of the relay, and is prone to malfunction and out-of-control due to unstable working voltage, and the working stability is poor; 2. With the development of applications, small-sized bistable relays have great development potential. Especially in recent years, there have been significant breakthroughs in the development of smart homes. However, due to the high-precision and high-quality requirements during the assembly of small-sized bistable relays, most of the small-sized bistable relays on the market currently cannot meet the insulation requirements and are difficult to be put into actual production.

[0016] Compared with the prior art, the small bistable high-insulation process structure relay proposed by the present invention can solve the problems that the existing power relay needs to be continuously powered on to maintain the closed state, resulting in high energy consumption and low stability.

[0017] The above one or more technical solutions have the following beneficial effects: 1. In a small bistable high-insulation process structure relay, based on the matrix process of the relay, the production and assembly operations of high-insulation relay products can be realized. At the same time, the potting (epoxy resin) process of the relay coil magnetic circuit inside the relay can greatly improve the insulation performance of the relay. After the iron core is magnetized by applying a positive DC pulse voltage, the magnetic force of the ring magnet magnetizing the iron core alone can keep the moving contact in the closed state unchanged, and the coil does not need to be continuously powered on, greatly reducing the energy consumption, the temperature rise of the relay is smaller, and the safety is higher; 2. In a small bistable high-insulation process structure relay, the bistable structure relay includes a setting process and a reset process. Among them, the setting process is: when it is necessary to make the relay in the closed state, a positive DC pulse voltage is applied to the relay coil. The relay coil generates a magnetic field, which interacts with the magnetic field of the permanent magnet, so that the moving reed of the relay is attracted and contacts the static contact, thereby realizing the closing of the circuit, and the moving contact and the static contact are locked in the closed state by the moving reed to ensure the stable operation of the relay. The reset process is: when it is necessary to make the relay in the open state, a reverse DC pulse voltage is applied to the relay coil. The magnetic field generated by the coil is opposite to the magnetic field direction of the permanent magnet, so that the moving reed is repelled and separated from the static contact, realizing the opening of the circuit, and the moving contact is restored to the initial position by the spring; 3. In a small bistable high-insulation process structure relay, through the design of the insulating sheet surrounding structure and the potting operation of the automatic dispensing equipment, the potting operation of the magnetic circuit (coil skeleton and relay coil) can be realized, and the design of high and low voltage insulation of the relay can be achieved.
