[0037] Example

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, this embodiment provides a control box, including a shell 10, a control circuit board 20, a wiring terminal 30 and a push button switch 40, the shell 10 includes a lower base shell 101 and an upper cover 102 covering the lower base shell 101; the control circuit board 20 is provided with a main chip 201, a lighting control chip 202 whose input end is electrically connected to the main chip 201, and a communication interface chip 203 whose input end is electrically connected to the main chip 201; a plurality of wiring terminals 30 are provided, and the wiring terminals 30 are electrically connected to the control circuit board 20, and a plurality of plug holes 103 for aligning and avoiding the wiring terminals 30 are provided on the lower base shell 101 and / or the upper cover 102; the push button switch 40 is provided on the shell 10, and the push button switch 40 is electrically connected to the main chip 201; or, the push button switch 40 is provided on the control circuit board 20, and a through hole for avoiding the push button switch 40 is provided on the upper cover 102.

[0039] Specifically, the housing 10 can be assembled by combining the lower base 101 and the upper cover 102, and then secured with screws or bolts to achieve a secure assembly. Simultaneously, the control circuit board 20 is clamped and / or locked within the housing 10, i.e., the control circuit board 20 can also be secured by locking, and then fully positioned in conjunction with the clamping of the lower base 101 and the upper cover 102.

[0040] Furthermore, the control circuit board 20 can be fixedly mounted with a key switch 40, a main chip 201 (e.g., a 51 series single-chip microcomputer; Intel chips such as I3, I5, or I7, etc.), a light control chip 202 (e.g., an IS31FL3731 chip or an SM2082 series chip), a communication interface chip 203 (which can be an RS485 communication interface chip 203), and a terminal block 30. These can be secured by pins and soldering. Regarding the key switch 40 disposed on the control circuit board 20, a through hole is designed in the upper cover 102 to expose the key switch 40 for a user to press. At the same time, the terminal block 30 is also designed with a socket 103 to facilitate electrical connection to external electrical equipment.

[0041] During operation, a switch is provided on the main chip 201, connecting the power line to the terminal 30. This switch can be designed as an electrically controlled relay switch 204 or a physical push-button switch. Turning the switch on connects the terminal 30, and turning it off closes the terminal 30. If the relay switch 204 is used for operation, it is electrically connected between the light terminal 302 and the main chip 201. The switch can be turned on or off according to the information from the main chip 201, achieving an automatic operation effect and achieving the purpose of turning external devices on and off.

[0042] Furthermore, the design of the button switch 40 can be used as a mode switching switch. By operating the button switch 40 to switch different modes or functions, matching operations for different devices can be formed, improving the effect of adapting to different device models during use and improving adaptability.

[0043] like Figure 4 and Figure 5 As shown, this embodiment also includes an indicator circuit board 50, which is equipped with several indicator lights 501. A push button switch 40 is also provided on the indicator circuit board 50. The indicator circuit board 50 is electrically connected to the main chip 201. A display hole for the indicator lights 501 to pass through, or a transparent plate for viewing the brightness of the indicator lights 501, is provided in the middle of the upper cover 102. The indicator lights 501 and push button switch 40 can be mounted on the indicator circuit board 50 so that the indicator lights 501 and the push button are positioned at the top of the upper cover 102 for easy operation or viewing. The indicator lights can extend beyond the upper cover 102 for viewing, or can be protected by a transparent plastic plate. The on / off status of the indicator lights 501 can also be viewed, improving user convenience. Furthermore, by viewing the on / off status of the indicator lights 501, the control box's predetermined status information can be displayed for easy reading.

[0044] like Figure 4As shown, in this embodiment, the wiring terminals 30 include a plurality of communication wiring terminals 301 and a plurality of lighting wiring terminals 302. The communication wiring terminals 301 and the lighting wiring terminals 302 can be slots for power cords, such as ATX power supply slots (Advanced Technology Extended, which means motherboard specifications in Chinese). The sockets of the communication wiring terminals 301 are arranged toward the sides of the upper cover 102 and / or the lower base shell 101, and the sockets of the lighting wiring terminals 302 are arranged toward the top surface of the upper cover 102. The different direction designs can avoid the interfaces being concentrated on one side, while reducing the size of the control box in a single direction, and fully designing the structural characteristics of the control box.

[0045] like Figure 2 and Figure 5 As shown, this embodiment also includes a guide rail 60. The bottom surface of the lower base 101 is provided with a slide groove 1011 that slidably cooperates with the guide rail 60. The guide rail 60 can be a DIN rail 60. The DIN rail 60 is a German industrial standard. Using the guide rail 60 is a mounting method for industrial electrical components. Electrical components that support this standard can be easily clipped onto the guide rail 60 without the need for screws, which also facilitates maintenance. The guide rail 60 is fastened to the lower base 101 with screws or bolts to provide the required support or fixed placement, improving practicality.

[0046] like Figure 5 As shown, this embodiment also includes a wire support 70. Two support plates 701 are symmetrically arranged on one side of the wire support 70, and a retaining groove 702 is formed between the two support plates 701 to accommodate the housing 10. A plurality of wire management holes 703 are arranged in a rectangular array on the surface of the wire support 70. When a large number of terminal blocks 30 are designed and a large number of external devices need to be connected, a large number of power cables or data cables will be plugged into the control box. The wire management holes 703 on the wire support 70 are used to regularly limit the position of the cables, thereby achieving neat and orderly cable management.

[0047] like Figure 3 As shown, in this embodiment, multiple locking hole supports 1012 are spaced apart on the lower case 101, and the upper cover 102 is provided with locking grooves (not shown) aligned with the locking hole supports 1012. The control circuit board 20 is provided with locking through holes 205 that avoid the locking hole supports 1012. The upper cover 102 and the lower case 101 can be aligned and assembled by the locking grooves and locking through holes 205, and then locked with screws, achieving the effect of facilitating disassembly and assembly while improving the stability of the structure.

[0048] like Figure 2 and Figure 4As shown, in this embodiment, the control circuit board 20 is provided with a data connector 80 and a power connector 81, so that an external power source can be connected to provide power to the control box. The data connector 80 is designed to connect to the main chip 201, and the corresponding program can be stored in the external device to achieve the desired purpose.

[0049] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
