Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to a time control switch. Background Art

[0002] In the fields of automation and power control, a time control switch, as a device that can automatically connect or disconnect a circuit according to a preset time program, has a wide range of applications. With the development of technology, the requirements for the performance, stability, and ease of use of time control switches are also constantly increasing. Traditional time control switches usually adopt a single circuit board design, integrating functions such as power supply, control, and backup power supply on the same circuit board. Such a design is simple, but there are many inconveniences in maintenance and upgrading. In addition, since all functions are concentrated on one circuit board, once a failure occurs, the entire time control switch may not work properly, reducing the reliability of the system. Summary of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a time control switch with a simple structure, reliable connection, and easy maintenance.

[0004] To achieve the above purpose, the utility model adopts such a time control switch, which includes a housing, a power supply circuit board, a time control switch circuit board, and a backup power supply transfer board arranged in the housing. A power supply module is provided on the power supply circuit board, a backup battery is provided on the backup power supply transfer board, and a time control switch module is provided on the time control switch circuit board.

[0005] Compared with the prior art, the beneficial effects of the above structure are as follows: By separately designing the power supply, time control switch, and backup power supply functions on independent circuit boards, a modular structure is formed, enabling each module to be maintained, replaced, or upgraded independently without replacing the entire time control switch, greatly improving the maintainability and expandability of the device. The introduction of the backup power supply transfer board enables the time control switch to automatically switch to backup battery power supply when the main power supply fails, ensuring the continuous operation of the device.

[0006] This utility model is further configured such that the power supply circuit board is located at the bottom of the housing, the backup power supply adapter board is located directly above the power supply circuit board, the time control switch circuit board is located directly above the backup power supply adapter board, the time control switch circuit board is provided with pin headers, the backup power supply adapter board is provided with a first row of female connectors on the back, and the power supply circuit board is provided with a second row of female connectors on the front corresponding to the first row of female connectors provided on the back of the backup power supply adapter board. The time control switch circuit board is connected and matched by sequentially plugging the first row of female connectors provided on the back of the backup power supply adapter board from top to bottom and the second row of female connectors provided on the front of the power supply circuit board. The plugging connection method of the female connectors and pin headers is used to connect the circuit boards. This connection method has the characteristics of stability and reliability, reduces the risk of failures caused by poor connections, improves the stability of the entire system. The power supply circuit board is located at the bottom, which can better utilize the heat dissipation space at the bottom. The backup power supply adapter board and the time control switch circuit board are arranged in sequence on the top, which is conducive to the natural convection and dissipation of heat, improves the overall heat dissipation efficiency, and reduces the impact of overheating problems on the circuit performance.

[0007] This utility model is further configured such that a rotary cover is provided on the top side of the housing. One end of the rotary cover is provided with a pivoting portion, and the housing is provided with two vertically upward protruding pivoting arms. The pivoting portion is pivotally installed inside the two pivoting arms to form a movable connection. The design of the rotary cover allows users to open or close the top of the time control switch through a simple rotation action without using additional tools or complex operations, greatly improving the convenience of use.

[0008] This utility model is further configured such that the housing includes a base and a cover. The base is provided with a clamping block, and the cover is provided with a clamping groove corresponding to the clamping block provided on the base to form a clamping fit. Through the clamping fit of the clamping block and the clamping groove, a tight connection is formed between the base and the cover, ensuring the overall stability of the housing, being able to effectively resist external impacts and vibrations, and protecting the internal circuit boards and other components from damage.
