Circuit boards play a key role in electronic devices, providing a platform for electrical connections, support and organization of electronic components.

[0003] When air conditioners are manufactured, a variety of electronic control modules are installed inside. When these electronic control modules are operated in a unified manner, most of them need to be connected through circuit boards, so that the air conditioner modules can work by receiving signals from the control circuit boards.

[0004] When the existing circuit boards are in use, most of the surfaces are welded with contacts, and the terminal plugs are connected through the contacts to connect the circuit boards to the air-conditioning modules. However, the positions of the contacts are mostly fixed. When plugging with the air-conditioning module, the position of the terminals cannot be adjusted according to the position of the air-conditioning module, which will cause the circuits of some air-conditioning modules to be too short and require external circuits, which is troublesome and inconvenient to operate. In addition, when multiple groups of existing circuit boards are spliced ​​and combined, most of them are fixed by bolts. However, the bolts require special tools to repeatedly rotate the bolts when disassembling the circuit boards, which is inconvenient during disassembly. Utility Model Content

The inner wall of the fixing block 13 is clamped with a fixing frame 5 through a limiting mechanism. The fixing frame 5 is provided to leave a gap between the circuit board A1 and the circuit board B4 to prevent them from piling up, which would affect the temperature of the circuit board A1 and the circuit board B4 and cause a short circuit.

[0025] See also Figure 4 The limiting mechanism includes a card block 15, the bottom end of the card block 15 is provided with an inclined surface, and an empty groove that fits the card slot 6 is opened in the middle. The card block 15 is elastically connected to the inner wall of the fixed block 13 through a return spring 14, one end of the return spring 14 is fixedly connected to the outer side wall of the card block 15, and the other end of the return spring 14 is fixedly connected to the inner side wall of the fixed block 13. When the inclined surface of the card block 15 contacts the inner wall of the card slot 6, it squeezes the card block 15 to move on the inner wall of the fixed block 13 until the card block 15 is fully inserted into the inner wall of the card slot 6. 5 will be elastically acted upon by the reset spring 14 to return to the initial position, so that the empty slot is engaged with the card slot 6, the card block 15 is slidably connected to the inner wall of the fixed block 13, and the outer side wall of the card block 15 is engaged with the card slot 6, and the engagement between the two enables the circuit board A1 and the circuit board B4 to be spliced ​​and combined together to prevent the two from falling off during use, the fixed block 13 penetrates and is slidably connected to the inner wall of the card slot 6, the bottom end of the outer wall of the fixing frame 5 is fixedly connected with the circuit board B4, and a plurality of groups of card slots 6 are provided on the surface of the fixing frame 5.

[0026] See also Figure 1-Figure 2A bracket 2 is fixedly connected to the surface of the circuit board A1, and contacts 3 are fixedly connected on both sides of the surface of the circuit board A1. A slider 7 is slidably connected to the inner side wall of the bracket 2, and a terminal 12 is fixedly connected to the top of the outer wall of the slider 7. The terminal 12 is provided to allow the air-conditioning module to be connected to the circuit board A1, so that the air-conditioning module can be operated through the circuit board A1. The top of the inner wall of the slider 7 is elastically connected to the contact block 9 through a limit spring 8, and the bottom end of the outer wall of the contact block 9 is clamped with the surface of the contact 3. The clamping between the two allows the signal at the terminal 12 connected to the upper end of the contact block 9 to be connected to the contact 3, and the position of the terminal 12 is fixed to prevent the terminal 12 from sliding during use.

[0027] See also Figure 3 The contact block 9 is slidably connected to the inner wall of the slider 7, and the sliding column 11 is slidably connected to the inner wall of the slider 7. One end of the limit spring 8 is fixedly connected to the top of the outer wall of the contact block 9, and the other end of the limit spring 8 is fixedly connected to the top of the outer wall of the slider 7. The position of the terminal 12 is adjusted by moving the contact block 9 on the inner wall of the slider 7 to squeeze the limit spring 8. When it is adjusted to a suitable position, the contact block 9 is released and it will be elastically acted upon by the limit spring 8 to restore it to its initial position. The outer side wall of the contact block 9 is fixedly connected with the sliding column 11, and the top of the outer wall of the contact block 9 is fixedly connected with the telescopic rod 10. The inner wall of the telescopic rod 10 is provided with an electric control circuit.

The top of the outer wall of the telescopic rod 10 is fixedly connected to the terminal 12, and the top of the outer wall of the telescopic rod 10 passes through the top of the inner wall of the slider 7.

[0028] Working principle: When it is necessary to connect the circuit board A1 with the electronic control module of the air conditioner, the sliding column 11 can be grasped to drive the contact block 9 to move upward on the inner wall of the slider 7. At this time, the telescopic rod 10 will telescope and move, and the limit spring 8 will be elastically compressed to allow its bottom end to disengage from the contact 3 at the current position of the circuit board A1, so as to push the slider 7 to move on the inner wall of the bracket 2, and adjust the position of the terminal 12 according to the position of the air conditioner installation module. When adjusting the position of the corresponding air-conditioning module, release the sliding column 11. At this time, the contact block 9 will be manually limited by the elastic action of the spring 8 to restore the contact block 9 to its initial position so as to contact with the contact 3 at the current position of the circuit board A1, thereby making the contact block 9 contact with the contact 3, so that the signal of the circuit board A1 can be transmitted to the terminal 12.

[0029] At the same time, when combining and splicing circuit board A1 with circuit board B4, the fixing block 13 at the bottom end of circuit board A1 is inserted into the card slot 6 of the fixing frame 5 on the surface of circuit board B4. At this time, the inclined surfaces of the two groups of card blocks 15 on the inner wall of the fixing block 13 will first contact the inner wall of the card slot 6, thereby squeezing the two groups of card blocks 15 to move on the inner wall of the fixing block 13, until the fixing block 13 is fully inserted into the inner wall of the card slot 6, the two groups of card blocks 15 will be elastically acted upon by the reset spring 14, restoring them to their initial positions, so that the empty grooves on their surfaces can contact and engage with the inner wall of the card slot 6, thereby quickly splicing and fixing circuit board A1 and circuit board B4.
