Description

Technical Field

[0001] This utility model relates to the field of control circuit boards, and in particular to a control circuit board that is easy to wire. Background Technology

[0002] A control circuit board is a circuit board that plays a control role. It is the control center of an air conditioning system, receiving signals from the remote control and controlling the air conditioner's operation status based on these signals, such as turning it on and off, adjusting the temperature, and setting the fan speed. The microprocessor on the circuit board processes and sends out corresponding control signals to ensure that the air conditioner operates according to the user's needs. By providing current and voltage control, it ensures the normal operation and efficient functioning of the equipment. The control circuit board needs to be wired to ensure the integrity of the circuit. The various components on the circuit board need to be connected by wires to form a complete circuit loop, thereby ensuring that the current can flow normally and realize the circuit's function.

[0003] A search revealed that Chinese Patent Publication No. CN217848488U discloses a circuit board that facilitates wiring. By setting a limiting mechanism, the wedge-shaped blocks on both sides are squeezed to provide a certain auxiliary positioning effect for the plug. During insertion, the plug is aligned with the slot, preventing misalignment that could damage the slot and plug. This improves the accuracy of the connection between the slot and plug during wiring.

[0004] In the above technical solution, the limiting mechanism is used to prevent the plug from being misaligned and damaged when it is connected to the circuit board. However, after the circuit board is connected, the connecting wire may be pulled off or not fully connected due to accidental contact by external personnel. When this happens, there is no way to remind the staff of the wiring error, which reduces the wiring effect and wiring stability. Therefore, a control circuit board that is easy to connect is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a control circuit board that is easy to wire, aiming to improve the problem that the existing control circuit boards that are easy to wire do not provide warnings to workers when the wiring is incomplete due to external pulling force after wiring, resulting in a decrease in wiring stability.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a control circuit board for easy wiring, comprising a circuit board body 1, a connector 2 on the surface of the circuit board body 1, a fixing shell 3 fixedly connected to the surface of the circuit board body 1, the fixing shell 3 being fitted onto the outer wall of the connector hole on the circuit board body 1, the connector hole being inserted into the connector 2 to complete the wiring, the outer wall of the fixing shell 3 having a through groove 4, the inner wall of the fixing shell 3 having a groove 5, the inner wall of the groove 5 being fixedly connected to a fixing rod 6, the outer wall of the fixing rod 6 being fitted with a limiting spring 7, the bottom end of the limiting spring 7 being fixedly connected to a pressure plate 8, the upper surface of the circuit board body 1 being fixedly connected to a switch 9, the switch 9 controlling the opening and closing of an alarm 16, the alarm 16 being in the closed state when the switch 9 is subjected to force, and the alarm 16 emitting a beeping alarm sound when the switch 9 is not subjected to force, the outer wall of the connector 2 being fixedly connected to a protruding plate 10, the protruding plate 10 being able to enter through the through groove 4 and contact the switch 9 to apply force, the outer wall of the fixing shell 3 being fixedly connected to the alarm 16, and the surface of the fixing shell 3 being provided with a positioning component.

[0033] Reference Figures 3-5 The inner surface of the fixed shell 3 is adapted to the outer wall of the connector 2. The top end of the limiting spring 7 is fixedly connected to the top end of the inner wall of the groove 5. The inner wall of the lower pressure plate 8 is slidably connected to the outer wall of the fixed rod 6. The positioning assembly includes a positioning hole 11, which is opened on the outer wall of the connector 2. The inner wall of the positioning hole 11 is adapted to the outer wall of the positioning rod 12. The upper surface of the positioning rod 12 is provided with a downward sliding surface 13, which is inclined downward so that the connector 2 can be aligned with the positioning rod after being embedded in the fixed shell 3. 12. The sliding surface 13 serves to allow the connector 2 to naturally transition to its end face and squeeze it when it comes into contact with it. The inner wall of the fixed shell 3 is slidably connected to the slide rod 14. The slide rod 14 is arranged in a horizontal I-shape. The I-shaped slide rod 14 will not fall out of the fixed shell 3 and allows the telescopic spring 15 to have a mounting force point. The outer wall of the slide rod 14 is fixedly connected to the telescopic spring 15. The end of the telescopic spring 15 away from the slide rod 14 is fixedly connected to the inner wall of the fixed shell 3. The telescopic spring 15 is sleeved on the outer wall of the slide rod 14. The end of the slide rod 14 is fixedly connected to the positioning rod 12.

[0034] Reference Figure 5A rotating shaft 17 is rotatably connected to the outer wall of the fixed shell 3. A limiting rod 18 is fixedly connected to the end of the rotating shaft 17. An arc-shaped groove 19 is opened on the outer wall of the fixed shell 3. A connecting block 20 is slidably connected to the inner wall of the arc-shaped groove 19. A Velcro 21 is fixedly connected to the end of the slide rod 14. A Velcro 22 is fixedly connected to the outer wall of the limiting rod 18. The Velcro 21 is located outside the fixed shell 3, and the side of the Velcro 21 away from the Velcro 22 is fixedly connected to the end of the slide rod 14 away from the positioning rod 12. The limiting rod 18 can limit the slide rod 14 by the adhesion of the Velcro 21 and the Velcro 22.

[0035] Working principle: When connector 2 is inserted into the connecting hole, it will be embedded inside the fixed housing 3. As connector 2 gradually descends inside the fixed housing 3, it will contact the sliding surface 13 and press against the positioning rod 12. The telescopic spring 15 will then press the sliding rod 14 towards the outside of the fixed housing 3. At the same time, the convex plate 10 contacts the lower pressure plate 8, causing the lower pressure plate 8 to slide downwards onto the fixed rod 6. The limit spring 7 will be stretched until connector 2 is fully embedded in the connecting hole. The convex plate 10 will then press against the lower pressure plate 8, causing it to press the end of the switch 9. Simultaneously, the positioning hole 11 and the positioning rod 12 will be aligned. Then, the telescopic spring 15 rebounds, causing the slide rod 14 to slide towards the fixed shell 3, so that the positioning rod 12 is embedded in the positioning hole 11, providing a limiting force to the connector 2. Then, the plug card on the surface of the switch 9 is pulled out, so that the switch 9 can operate to control the reminder 16. Finally, the limiting rod 18 is manually moved to make the rotating shaft 17 rotate. At the same time, the connecting block 20 slides in the arc groove 19 to limit its movement trajectory. Finally, the fasteners 21 and 22 are attached to limit the sliding rod 14, reducing the risk of the connector 2 detaching from the fixed shell 3.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
