Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] like Figure 1-6 As shown, a dustproof and waterproof junction box integrated into an electrical cabinet includes an electrical cabinet body 1 and a junction box 2 disposed inside it. A shielding cover 4 is rotatably disposed on the junction box 2. Sealing blocks 5 are arranged in a linear array on the shielding cover 4. An access groove 21 is linearly arranged on the junction box 2. A terminal block 3 is disposed in the access groove 21. A fixing groove 31 for connecting the end of a cable is provided on the terminal block 3. The shielding cover 4 is driven to rotate and approach the junction box 2 so that the sealing blocks 5 are embedded in the access groove 21 to shield the terminal block 3.

[0025] Specifically, such as Figure 1 As shown, the terminal block 2 is installed inside the electrical cabinet 1, and the cover 4 is provided with a rotating part 42. The rotating part 42 is rotatably mounted on the mounting part 25 of the terminal block 2. The cover 4 is provided with several sealing blocks 5. The end of the cable to be connected can be connected to the fixing groove 31 of the terminal block 3 through the access groove 21. Then, the cover 4 is rotated so that the sealing blocks 5 are rotated and embedded into the access groove 21. Thus, the sealing blocks 5 are used to cover and protect the access groove 21 and the terminal block 3, so as to prevent moisture or dust from entering the access groove 21 and causing short circuit damage or moisture corrosion damage to the terminal block 3, thereby improving the service life and stability of the terminal block 3.

[0026] In the above technical solution, the shielding cover 4 is rotated so that a number of sealing blocks 5 are rotated and embedded into the access groove 21. The sealing blocks 5 are used to cover and protect the access groove 21 and the terminal block 3, so as to prevent water vapor or dust from entering the access groove 21 and causing short circuit damage or water vapor corrosion damage to the terminal block 3, thereby improving the service life and stability of the terminal block 3.

[0027] As a further embodiment of this utility model, the terminal block 3 is axially slidably disposed in the access groove 21, and the access groove 21 is provided with a receiving groove 23. The cover 4 is driven to rotate and move closer to the terminal block 2 so that the terminal block 3 is axially slidably retracted into the access groove 21, and the fixing groove 31 moves to be flush with the receiving groove 23.

[0028] Specifically, such as Figure 3As shown, the terminal block 3 is axially slidably disposed in the sliding groove 22 opened on the terminal block 2. When the cover 4 rotates away from the terminal block 2, the terminal block 3 is located at the high position of the sliding stroke so that the cable can be connected to the fixing groove 31 of the terminal block 3. When the cover 4 rotates closer to the terminal block 2, the terminal block 3 is driven to slide closer to the low position of the sliding stroke, thereby causing the terminal block 3 to drive the end of the cable to retract into the receiving groove 23, thereby further improving the protection of the fixing groove 31 and the cable connection end, and further preventing the cable end or the terminal block 3 from being invaded by moisture or dust, which facilitates actual maintenance and use, and improves the safety and convenience of use.

[0029] As a further embodiment of this utility model, a transmission assembly is provided inside the terminal block 2. The transmission assembly includes a first transmission shaft 61, a second transmission shaft 62, and a synchronous belt 63. A rack portion 32 is provided on the terminal block 3, and a partial gear ring portion 41 is provided on the cover 4. The first gear ring portion 611 of the first transmission shaft 61 is coupled to the rack portion 32. The first transmission shaft 61 rotates synchronously with the second transmission shaft 62 through the synchronous belt 63. The second gear ring portion 621 of the second transmission shaft 62 is coupled to the partial gear ring portion 41.

[0030] Specifically, such as Figure 3 As shown, the first drive shaft 61 and the second drive shaft 62 are rotatably mounted in the terminal block 2, and the first drive shaft 61 rotates synchronously with the second drive shaft 62 via a synchronous belt 63. Figure 5 As shown, the first gear ring portion 611 of the first drive shaft 61 is coupled to the rack portion 32, and the second gear ring portion 621 of the second drive shaft 62 is coupled to the partial gear ring portion 41. When the shielding cover 4 is driven to rotate relative to the terminal block 2, the partial gear ring portion 41, the second drive shaft 62, the synchronous belt 63, and the first drive shaft 61 are driven in sequence to drive the terminal block 3 to slide and lift axially. In this way, the first drive shaft 61, the second drive shaft 62, and the synchronous belt 63 are used to improve the driving stability of the shielding cover 4 on the terminal block 3.

[0031] As a further embodiment of this utility model, the bottom surface of the access slot 21 is used to support the cable to form a support surface 211. The sealing block 5 is provided with a concave arc groove 51. The sealing block 5 moves with the cover 4 and is embedded in the access slot 21 so that the concave arc groove 51 and the support surface 211 clamp the access cable.

[0032] Specifically, the bottom surface of the access slot 21 is used to support the cable to form a support surface 211. The sealing block 5 has a concave arc groove 51. When the cover 4 rotates to drive the sealing block 5 into the access slot 21, the cable is connected to the terminal 3 through the access slot 21. At this time, the concave arc groove 51 of the sealing block 5 and the support surface 211 clamp the cable body to further fix and seal the cable. This prevents the cable from moving and pulling the terminal 3, thus avoiding damage. It also prevents moisture from entering the access slot 21 along the cable surface and damaging the terminal 3.

[0033] As a further embodiment of this utility model, the terminal block 2 is provided with a through hole 24 that passes through the access groove 21, the sealing block 5 is provided with a through hole 52, and the sealing block 5 is also provided with a sealing ring 521 located on the periphery of the through hole 52. The sealing block 5 moves with the cover 4 and is embedded in the access groove 21 so that the sealing ring 521 is fitted into the through hole 24, and the through hole 52 is connected to the through hole 24.

[0034] Specifically, such as Figure 6 As shown, the terminal block 2 has a through hole 24 that passes through the access slot 21, such as Figure 4 As shown, the sealing block 5 has a through hole 52. When the cover 4 rotates to drive the sealing block 5 into the access groove 21, the cable is connected to the terminal 3 through the access groove 21. The sealing block 5 rotates until the sealing ring 521 is embedded in the through hole 24. At this time, the through hole 52 is connected to the through hole 24. The through hole 24 and the through hole 52 can then be used to ventilate and dissipate heat from the cable and the terminal 3 in the access groove 21, so as to avoid the cable damage caused by the terminal 3 being too hot and improve the safety of use.

[0035] As a further embodiment of this utility model, the sealing block 5 is provided with a ball top 53, and the terminal block 3 is provided with a ball groove 33. The sealing block 5 moves with the cover 4 and is embedded in the access groove 21 so that the ball top 53 is pressed into the ball groove 33.

[0036] Specifically, the sealing block 5 is provided with a spherical top 53, and the terminal block 3 is provided with a spherical groove 33. When the cover 4 rotates to drive the sealing block 5 into the access groove 21, the cable is connected to the terminal block 3 through the access groove 21. The spherical top 53 rotates and contacts and is pressed into the spherical groove 33, thereby allowing the spherical top 53 to apply pressure to the terminal block 3 to slide to a lower position. Furthermore, since the spherical top 53 and the spherical groove 33 are coaxially contacted and pressed to reduce the radial vibration of the terminal block 3 during the sliding process, the pulling force of the terminal block 3 on the end of the connected cable is reduced, thus improving the protection of the cable.

[0037] As a further embodiment of this utility model, a pressure plate 7 parallel to the concave groove 51 is provided inside the sealing block 5, and an extension 71 extending to the top of the ball 53 and the through hole 52 is provided on the pressure plate 7.

[0038] Specifically, such as Figure 3 As shown, a pressure plate 7 parallel to the concave arc groove 51 is provided inside the sealing block 5, and the extension 71 extends between the spherical top 53 and the through hole 52. When the shielding cover 4 rotates to drive the sealing block 5 into the access groove 21, the cable is connected to the terminal 3 through the access groove 21. The spherical top 53 rotates and contacts and is pressed into the spherical groove 33, so that the spherical top 53 can apply pressure to the terminal 3 to slide to a lower position. At this time, the spherical top 53 is pressed and squeezes the extension 71 of the pressure plate 7 to move closer to the through hole 52, so that the end of the pressure plate 7 facing away from the extension 71 is pressed towards the concave arc groove 51. Thus, the pressure plate 7 is used to further improve the clamping stability and sealing performance of the cable by the concave arc groove 51 and the supporting surface 211, and further avoid the problem of water vapor intruding into the access groove 21 along the cable surface and causing water vapor erosion damage.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
