Description

[0002] A combination relay is an electrical component composed of multiple relays. It has basic functions such as electrical isolation, current amplification, and voltage conversion. It can realize a variety of operating functions, such as disconnection, attraction, and repetition. It is widely used in automation control and power circuits. Taking the combination pressure relay as an example, by adjusting the fine-tuning screw in the pressure switch, the system's working pressure value can be pre-set. When the system pressure reaches the set value, the pressure switch will send a signal, and the relay will control the mechanical operation according to the signal, such as switching or power off. This type of relay is usually set with three different states, including storage state, reset state, and working state. In addition, combination relays have important applications in household appliances, transportation, industrial automation, construction and energy, and medical equipment. Through current amplification and current cut-off functions, combination relays can realize the control and protection of various electrical signals and improve the safety and stability of electrical equipment. In general, combination relays achieve functional integration and optimization by combining multiple relays, thereby improving the efficiency and reliability of the control system.

A round rod 9 is fixedly connected to the surface of the inner wall of the support block 8, and a clamping plate 10 is movably connected to the surface of the round rod 9. The top of the clamping plate 10 is movably connected to a connecting plate 11, and the inner side of the connecting plate 11 is fixedly connected to the front and back sides of the fixed frame 6.

[0029] refer to Figure 4 The top of the fixed frame 3 is fixedly connected with a reinforcement frame 12 , and the surface of the inner wall of the reinforcement frame 12 is fixedly connected with the surface of the sealing box 2 .

[0030] As a technical optimization solution of the utility model, by providing a reinforcement frame 12, the connection portion between the fixed frame 3 and the sealing box 2 can be reinforced to prevent it from being subjected to excessive force and causing loosening or falling off.

[0031] refer to Figure 5 A pressing plate 13 is fixedly connected to the outer side of the card plate 10 , and the pressing plate 13 is used in conjunction with the card plate 10 .

[0032] As a technical optimization solution of the utility model, by providing a pressing plate 13, the card plate 10 can be moved, making it easier for the hand to exert force during the process of moving the card plate 10.

[0034] As a technical optimization solution of the present invention, by providing the protrusion 14, the friction force on the top of the pressing plate 13 can be increased to prevent the difficulty in use caused by slippery hands during use.

[0035] refer to Figure 2 The top of the card frame 5 is provided with an arc angle 15, and the arc angle 15 is used in conjunction with the card frame 5 and the fixed frame 3.
