[0001] The utility model relates to the technical field of air-conditioning wiring harness terminals, in particular to a wiring harness terminal for air-conditioning connecting wires. Background Art

[0002] In the electrical system of air conditioners, wiring harness terminals are crucial connectors, responsible for the critical functions of power and signal transmission. During the long-term operation of air conditioners, the connection status of electrical components such as wires and wiring harnesses is directly related to the operating efficiency and safety of the equipment. However, during daily use, especially during inspection and maintenance, wiring harness terminals are susceptible to external interference or improper operation, which can affect the stability of the connection.

[0003] Most of the current air-conditioning equipment is composed of multiple wiring harnesses, which are connected to electrical components or connecting wires through terminals. The terminals cannot be protected during connection, resulting in the movement or pulling of the wiring harness during repair, maintenance or sorting, which can easily apply additional tension to the terminals at the connection. Especially when the wiring harness is bundled too tightly or the space is narrow, it is easy to bump into the inside of the air conditioner and cause damage, causing the connection between the terminal and other wiring harnesses to loosen, and then the unstable connection terminal may cause poor contact, resulting in equipment failure or signal transmission interruption.

[0006] The protective mechanism also includes an anti-pull plate fixedly connected to the outer wall of the connecting wire harness, the outer wall of the connecting wire harness is provided with a threaded sleeve, and protective semicircular plates are fixedly connected on both sides of the lower protective box and the upper protective box. Two limit blocks are fixedly connected to the inside of the protective semicircular plates. The anti-pull plate is located in the middle of the two limit blocks, and the threaded sleeve is threadedly connected to the outer wall of the protective semicircular plate.

[0007] The inner wall of the lower protective box is fixedly connected with a fixing plate, the top of the fixing plate is fixedly connected with a sealing ring, the inner wall of the upper protective box is fixedly connected with a sealing plate, and the top of the sealing ring fits tightly on the bottom of the sealing plate.

[0024] like Figures 1 to 5As shown, a wiring harness terminal for an air-conditioning connection line includes a connection harness 1, one end of the connection harness 1 is fixedly connected to a terminal connector 2, the outer wall of the terminal connector 2 is provided with a protective mechanism for protecting the terminal connector 2 after connection, the protective mechanism includes a lower protective box 3 provided on the outer wall of the terminal connector 2, an upper protective box 4 is provided on the top of the lower protective box 3, and an accommodating cavity 10 is opened on the top of the upper protective box 4. The inner walls of both sides of the accommodating cavity 10 are slidably connected with a clamping plate 6, and both sides of the clamping plate 6 are fixedly connected with an extrusion spring 7, one end of the extrusion spring 7 is fixedly connected to the inner wall of the accommodating cavity 10, the shape of the clamping plate 6 is L-shaped, and the inner wall of the clamping plate 6 A snap-fitting block 8 is fixedly connected, and the shape of the snap-fitting block 8 is triangular. The inner wall of the snap-fitting groove 9 is adapted to the outer wall shape of the snap-fitting block 8. A snap-fitting groove 9 is provided on both sides of the lower protective box 3. The snap-fitting block 8 is snapped into the inner part of the snap-fitting groove 9. The protective mechanism also includes an anti-pull plate 11 fixedly connected to the outer wall of the connecting harness 1. The outer wall of the connecting harness 1 is provided with a threaded sleeve 12. Both sides of the lower protective box 3 and the upper protective box 4 are fixedly connected with a protective semicircular plate 13. The interior of the protective semicircular plate 13 is fixedly connected to two limit blocks 14. The anti-pull plate 11 is located in the middle of the two limit blocks 14, and the threaded sleeve 12 is threadedly connected to the outer wall of the protective semicircular plate 13;When the protective mechanism is in use, first place the terminal connector 2 connected with other wiring harnesses inside the lower protective box 3, then place the connecting wiring harness 1 on the protective semicircular plates 13 on both sides of the lower protective box 3, and at the same time put the anti-pull plate 11 on the connecting wiring harness 1 into the middle of the two limit blocks 14, and then buckle the upper protective box 4. At this time, the two sides of the lower protective box 3 will extend and squeeze the side walls of the clamping plate 6, and the clamping plate 6 will squeeze the extrusion spring 7. When the clamping slot 9 and the clamping block 8 are in the same horizontal plane, the extrusion spring 7 will release The clamping plate 6 is pushed by its own elastic force so that one end of the clamping plate 6 is completely fitted on the side walls of the lower protective box 3. Then the clamping plate 6 drives the clamping block 8 to enter the inside of the clamping groove 9, so that the lower protective box 3 and the upper protective box 4 can be fixed together, while also increasing the sealing between the lower protective box 3 and the upper protective box 4. Then the threaded sleeve 12 is threadedly connected to the outer wall of the protective semicircular plate 13, and then the protective semicircular plates 13 on the side walls of the lower protective box 3 and the upper protective box 4 can be fixed, and then maintenance can be carried out. The terminal connector 2 can be protected during connection to prevent the connection between the terminal connector 2 and other wiring harnesses from loosening when the connection harness 1 is pulled. At the same time, it can also prevent the connection between the terminal connector 2 and other wiring harnesses from colliding with the inner wall of the air conditioner when the connection harness 1 is moved, thereby preventing the terminal connector 2 from colliding with the inner wall of the air conditioner when the connection harness 1 is moved. By placing the connected terminal connector 2 inside the lower protection box 3 and the upper protection box 4 and fixing them in the protective machine, the terminal connector 2 can be completely protected to avoid direct impact from external objects. After the connection harness 1 and the anti-pull plate 11 are placed between the two limit blocks 14, the protective semicircular plate 13 is installed. When the connection harness 1 is pulled, the connection harness 1 will transfer the pulling force to the anti-pull plate 11. The anti-pull plate 11 is placed between the two limit blocks 14, thereby providing additional support so that the pulling force will not pull the connection of the terminal connector 2. This effectively prevents the terminal from loosening due to the movement or pulling of the harness during maintenance, ensures the stability of the electrical connection, and avoids signal interruption or equipment failure.

The sealing ring 16 is tightly fitted with the bottom of the sealing plate 17, which ensures the sealing when the lower protective box 3 and the upper protective box 4 are connected, and avoids short circuit and corrosion at the connection of the terminal connector 2 due to the external humid environment.

[0026] For further information, see the attached Figure 3As shown, a desiccant plate 18 for absorbing moisture in the air inside the lower protective box 3 and the upper protective box 4 is fixedly connected to the bottom of the fixed plate 15. The desiccant plate 18 can absorb the water vapor inside the lower protective box 3 and the upper protective box 4 to avoid a humid internal environment, thereby further protecting the terminal connector 2 when connected.

[0027] For further information, see the attached Figure 5 As shown, the middle part of the accommodating chamber 10 is rotatably connected with a disassembly block 5, and the two sides of the disassembly block 5 are arc-shaped. The side walls of the disassembly block 5 are in contact with the side walls of the clamping plate 6. The top of the disassembly block 5 passes through the outer wall of the upper protective box 4 and is fixedly connected with a twisting block 19. When the lower protective box 3 and the upper protective box 4 need to be disassembled, it is only necessary to rotate the twisting block 19. The twisting block 19 drives the disassembly block 5 to rotate. When the disassembly block 5 rotates, it will squeeze the clamping plates 6 on both sides. The clamping plates 6 are squeezed and the clamping block 8 is driven to leave the clamping groove 9, so that the lower protective box 3 and the upper protective box 4 can be disassembled, which is convenient for inspection and replacement.

[0028] For further information, see the attached Figure 4 As shown, a sealing strip 20 is fixedly connected between the side walls of the two limit blocks 14. The sealing strip 20 is fixedly connected to the inner wall of the protective semicircular plate 13. The sealing strip 20 fits tightly with the outer wall of the anti-pull plate 11. The sealing strip 20 prevents humid gas and water from entering the interior of the lower protective box 3 and the upper protective box 4 from the protective semicircular plate 13, thereby playing a waterproof role.
