[0002] During the operation of an air conditioner, the electronic control system plays a crucial role, and the electronic control box, as the core component of the electronic control system, directly affects the stable operation of the air conditioner and the personal safety of the user. The electronic control box is the control center of the air conditioner. The connection wires of various components inside the air conditioner need to be led into the electronic control box, which contains various high-voltage and low-voltage components. Of course, a grounding wire is also essential.

[0003] Currently, the connection between the air conditioner control box and the grounding wire is achieved by fixing the round terminal of the grounding wire into the grounding hole of the control box with grounding screws. The number of grounding screws required corresponds to the number of grounding wires, which is inefficient and seriously affects assembly efficiency. Utility Model Content

[0039] In the prior art, reference Figure 1 As shown, the current connection method between the air conditioner control box and the grounding wire is to fix the circular terminal of the grounding wire in the grounding hole of the control box by grounding screw 10. The number of grounding screws 10 required depends on the number of grounding wires, which is inefficient and seriously affects the assembly efficiency.

[0040] This utility model proposes an electrical control box.

[0041] Please see Figures 2 to 5 As shown, in one embodiment of the present invention, the electrical control box includes: a box body 100, a first terminal 200 and a second terminal 300, wherein the first terminal 200 is connected to the box body 100, and the second terminal 300 includes a connecting part 310 and a fixing part 320 connected to each other. The connecting part 310 is plugged into the first terminal 200, and the fixing part 320 is used to connect to the grounding wire 400.

[0042] In this embodiment, the first terminal 200 is connected to the housing 100, and the current or static electricity generated by the control box is transmitted to the first terminal 200 through the housing 100. The connecting part 310 of the second terminal 300 is plugged into the first terminal 200, and the fixing part 320 is pressed into the copper core of the grounding wire 400, forming a current flow path. The current passes through the first terminal 200 and the second terminal 300, and is further transmitted to the ground through the grounding wire 400. It can be understood that when the connecting part 310 of the first terminal 200 and the second terminal 300 is plugged in, one of the first terminal 200 and the second terminal 300 is the female end and the other is the male end; this is not limited in this embodiment. In addition, it should be noted that the housing 100, the first terminal 200, and the second terminal 300 are made of metal material capable of transmitting current.

[0043] The fixing part 320 and the connecting part 310 of the second terminal 300 are integrated into one structure, which ensures that the second terminal 300 has a certain strength. Furthermore, the fixing part 320 and the connecting part 310 are located at opposite ends of the second terminal 300, which avoids the grounding wire 400 interfering with the connection of the connecting part 310 to the second terminal, and also facilitates the routing of the grounding wire 400.

[0044] This utility model's technical solution uses a first terminal 200 to connect to the housing 100, and a second terminal 300 whose fixing part 320 is connected to the grounding wire 400. The connecting part 310 is plugged into the first terminal 200. In this way, static electricity generated in the control box or current generated during a short circuit can be transferred from the first terminal 200 to the second terminal 300, and further introduced to the ground through the grounding wire 400, preventing electric shock or other dangers. In this utility model's technical solution, the first terminal 200 and the second terminal 300 are plugged into each other to connect the control box to the grounding wire 400. Compared to the current method of connecting the control box to the grounding wire 400 by screwing in the grounding screw 10, this plug-in method improves installation efficiency. Especially when multiple grounding wires need to be connected, the number of grounding screws 10 required depends on the number of grounding wires 400, which is inefficient. However, in this technical solution, the grounding wires 400 are connected by plugging the first terminal 200 into the second terminal 300, which enables quick plugging and unplugging of the grounding wires 400 and greatly improves assembly efficiency.

[0045] refer to Figure 4 As shown, in one embodiment, the connecting part 310 is provided with a slot 311, and the first terminal 200 is inserted into the slot 311.

[0046] Specifically, the slot 311 is used to insert and accommodate the second terminal 300. The slot 311 has a notch at the free end of the second terminal 300, that is, the notch is located at the end of the connecting part 310 away from the fixing part 320. The slot 311 is adapted to the first terminal 200. The first terminal 200 is inserted into the slot 311 through the notch, thereby realizing the connection between the first terminal 200 and the second terminal 300. This facilitates assembly and greatly improves assembly efficiency.

[0047] In one embodiment, the connecting portion 310 includes a base plate 312 connected to the fixing portion 320 and a clamping spring 313 connected to the base plate 312, and a slot 311 is formed between the clamping spring 313 and the base plate 312.

[0048] In the specific implementation process, the base plate 312 is recessed to form a slot 311. The clamping spring 313 has two opposing ends, and the direction of the connection between the two ends is perpendicular to the insertion direction. One end is the connecting end, which is connected to the edge of the base plate 312 and is located on the side away from the bottom of the slot 311. The other end is the free end, which is used to clamp the first terminal 200. Specifically, after the first terminal 200 is inserted into the slot 311, the clamping spring 313 is pressed, so that the free end of the clamping spring 313 is pressed against the first terminal 200, thereby improving the stability of the connection between the first terminal 200 and the second terminal 300.

[0049] Furthermore, a clamping spring 313 is provided on each side of the base plate 312, and the two clamping springs 313 are bent towards each other. The two clamping springs 313 are respectively connected to opposite sides of the base plate 312, and the free ends of the two springs are close to each other. After pressing the clamping springs 313, the two free ends rotate toward the slot 311 respectively, and abut against the surface of the first terminal 200 in the slot 311, so as to press the first terminal 200 against the slot 311.

[0050] In practical implementation, the clamping spring 313 is curved, meaning the portion of the clamping spring 313 from the connecting end to the free end is curved and protrudes in the direction away from the slot 311. This avoids stress concentration in the clamping spring 313, maintaining good elasticity to clamp the first terminal 200. Furthermore, it is understandable that when assembling the grounding wire 400 of the electrical control box, the clamping spring 313 is usually pressed by hand; the contact surface between the hand and the clamping spring 313 is curved, avoiding any painful pressure. Moreover, the curved portion of the clamping spring and the first terminal 200 form a certain spatial volume, accommodating first terminals 200 with different structures.

[0051] In one embodiment, a guide slope 210 is provided at the end of the first terminal 200 away from the housing 100. In specific implementation, a guide slope 210 is provided at the connection between the end of the first terminal 200 and each side wall. When the first terminal 200 and the second terminal 300 are inserted, the guide slope 210 can play a guiding role to facilitate the insertion.

[0052] Understandably, in order to improve the strength and stability of the plug-in connection between the first terminal 200 and the second terminal 300, in one embodiment, the first terminal 200 is provided with a first limiting part, and the second terminal 300 is provided with a second limiting part in the slot 311. The first limiting part and the second limiting part are mutually limiting and cooperating to restrict the first terminal 200 from disengaging from the slot 311.

[0053] In this embodiment, after the first limiting part and the second limiting part cooperate, the displacement of the first terminal 200 and the second terminal 300 in the insertion direction can be restricted, so that the first terminal 200 and the second terminal 300 remain connected. The first limiting part and the second limiting part can be a structure for insertion and limiting with a pin and a socket, or it can be a structure for limiting with two snap-fits, which is not limited here.

[0054] In one embodiment, the first limiting part is configured as a limiting hole 220, and the second limiting part is configured as a limiting post 330, which is engaged in the limiting hole 220.

[0055] Specifically, the limiting hole 220 extends through the first end perpendicular to the insertion direction, and the limiting post 330 protrudes from the bottom of the slot 311. Thus, after the first terminal 200 is inserted into the slot 311, the limiting post 330 engages within the limiting hole 220, acting as a limit to prevent the second terminal 300 from falling out. Furthermore, the clamping spring 313 presses the first terminal 200 against the bottom of the slot 311 to restrict the displacement of the first terminal 200 perpendicular to the insertion direction. The cooperation of the limiting post 330 and the limiting hole 220 further restricts the displacement of the first terminal 200 and the second terminal 300 in the insertion direction, thereby maintaining the connection between the first terminal 200 and the second terminal 300 and improving the strength and stability of their connection.

[0056] In one embodiment, the second terminal 300 has several deformation grooves 314 around the limiting post 330. The deformation grooves 314 are formed in the base plate 312 and are located around the limiting post 330. Specifically, the base plate 312 has two deformation grooves 314, which are elongated holes, so that the part of the base plate 312 between the two deformation grooves 314 has a certain elasticity, so that the base plate 312 can cooperate with the clamping spring 313 to clamp the first terminal 200, thereby preventing the limiting post 330 from falling off the limiting hole 220 and further improving the stability of the connection between the first terminal 200 and the second terminal 300.

[0057] In another embodiment, after the first terminal 200 and the second terminal 300 are plugged in, they can be fixed by interference fit to prevent the first terminal 200 and the second terminal 300 from falling off each other.

[0058] In one embodiment, the first terminal 200 is integrally formed with the housing 100. In practical implementation, the first terminal 200 can be formed simultaneously with the housing 100 during sheet metal forming, reducing forming steps and improving production efficiency. This also ensures the transmission of current between the first terminal 200 and the housing 100.

[0059] refer to Figure 5As shown, in one embodiment, the electrical control box further includes a grounding plate 500, the first terminal 200 is integrally formed with the grounding plate 500, and the grounding plate 500 is connected to the box body 100.

[0060] In practical implementation, there may be a situation where the sheet metal thickness of the electrical control box is incompatible with that of the second terminal 300. In this embodiment, a grounding plate 500 with a thickness adapted to the second terminal 300 is used. The grounding plate 500 is connected to the box body 100, and the first terminal 200 is integrally formed on the grounding plate 500. The second terminal 300 is plugged into and connected to the first terminal 200. The box body 100 and the grounding plate 500 can be detachably connected or fixedly connected by welding, etc.

[0061] In one embodiment, the grounding piece 500 is fastened to the housing 100 by screws. While maintaining the appearance of the housing 100, the grounding piece 500 is fastened to the housing 100 by screws 510, which facilitates the assembly of the grounding piece 500 and also facilitates the replacement of different models of grounding pieces 500 to meet different grounding requirements, such as different requirements for grounding environment or number of grounding wires 400, etc.

[0062] In addition, it should be noted that even though the grounding plate 500 needs to be attached to the housing 100 by screws 510, the assembly efficiency is greatly improved compared to the current assembly of each grounding wire 400 attached by screws 510.

[0063] This utility model also proposes an air conditioning device, which includes an electrical control box as described in the above embodiments. The specific structure of the electrical control box is as described in the above embodiments. Since this air conditioning device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
