Description

Technical Field

[0001] This invention relates to the field of junction box technology, specifically to an easy-to-install waterproof cable junction box. Background Technology

[0002] Junction boxes are the terminals of distribution cables or optical cables, connecting the distribution cables or optical cables to the user's line section, and branching the main line. They play an important role. Junction boxes can be installed in narrow spaces such as cable trays, boxes, pipes, and cable trenches, without occupying the effective usable area of ​​the building. They are easy to install and do not require cutting the main cable.

[0003] Currently, the commonly used cable junction boxes require the branch cables to be connected and the top cover to be fastened during the wiring process. Then, glue is poured into the inside of the junction box, which is inconvenient to disassemble. In addition, most of the existing technology for installing junction boxes is bolt fixing, which is also troublesome to disassemble. In some technologies, the quick disassembly device is easily accidentally activated, causing the junction box to detach. Summary of the Invention

[0013] As a further description of the above technical solution: the pressure ring and the silicone pad have the same shape and structure.

[0014] This invention provides an easily installable waterproof cable distribution box, which has the following improvements and advantages compared to the prior art:

[0015] Firstly, when the insert is inserted into the slot, the bottom of the insert presses the limiting frame outward. When the upper end of the limiting frame is in the limiting groove, the upper end of the limiting frame is inserted into the limiting groove, completing the locking. When it is necessary to remove the insert from the slot, first move the moving plate with the second fixing frame inward, then move the moving plates on the adjacent side inward, then release the first moving plate, and continue to move the other moving plate inward, and so on. Finally, push the pressing plate inward, and the inner end of the pressing plate presses the limiting frame outward, thereby moving the limiting frame away from the limiting groove, so that the insert can be pulled out. The connecting mechanism can quickly connect and disassemble the lower box and the upper box with the mounting base, and the connecting mechanism can prevent accidental contact.

[0016] Secondly: The rotating column is placed in the circular groove at the lower end of the upper box. Through the transmission of the second rack, the first gear, the rotating column and the irregular block, the irregular block is moved away from the inclined plane. The slot will be stuck by the side wall of the rotating groove, automatically connecting the lower box and the upper box. At the same time, through the transmission of the second rack, the push rod, the first rack, the second gear, the third rack and the pressure ring, the pressure ring moves downward and presses the silicone pad downward, so that the silicone pad is more tightly attached to the upper surface of the lower fixing ring, and the waterproof performance is better.

[0017] Thirdly: When using, first fix the mounting base to the installation location, then snap the busbar and sub-line into the wire clamping slot in sequence, and place the sub-line between the two clamping plates. Then place the upper box on the lower box. The squeezing rod will squeeze the trapezoidal block inward, thereby clamping the sub-line tightly to prevent shaking and unstable connection.

[0018] In summary: the connecting mechanism allows for quick connection and disassembly of the lower and upper boxes to the mounting base, and also prevents accidental contact that could cause the junction box to detach. The sealing mechanism ensures a tighter fit between the silicone pad and the upper surface of the lower fixing ring, resulting in better waterproofing. The locking assembly allows for pre-connection of the lower and upper boxes, facilitating their movement together to the mounting base and preventing separation. The fixing mechanism clamps the sub-cables securely, preventing wobbling and unstable connections. Attached Figure Description

[0031] The connecting mechanism 6 includes a post 62 fixedly attached to the center of the lower surface of the lower housing 1, and limiting grooves 69 are provided on both opposite sides of the outer wall of the post 62. A movable plate 61 and a pressing plate 63 are movably inserted into the outer wall of the mounting base 3. There are three movable plates 61 and one pressing plate 63. The upper ends of the pressing plate 63 and two adjacent movable plates 61 are fixedly connected to a first fixing frame 64, and the upper end of the other movable plate 61 is fixedly connected to a second fixing frame 66. The first fixing frame 64 and the second fixing frame 66 are slidably disposed in the mounting base 3. The first fixing frame 64 and the groove 65 are provided with grooves 65 on the upper side of one end and the lower side of the other end. The upper surface of the mounting base 3 is provided with a slot, and the inner wall of the slot is... Both opposite sides are movably connected to limit frames 68, with the upper end of the limit frame 68 located in the slot and the lower end of the limit frame 68 located in the mounting base 3. A second spring 610 is fixed between the side wall of the limit frame 68 away from the slot and the mounting base 3. A first spring 67 is fixed between one end of the side wall of the moving plate 61 and the pressing plate 63 and the mounting base 3. The pressing plate 63 and the moving plate 61 are distributed in a ring with equal spacing. The length of the second fixed frame 66 is shorter than that of the first fixed frame 64.

A wire-locking groove 10 is provided at the junction of the sub-line 5 and the busbar 4, and the wire-locking groove 10 is made of elastic material.

[0032] Specifically, when the insert 62 is inserted into the slot, the bottom end of the insert 62 presses the limiting frame 68 outward. When the upper end of the limiting frame 68 is located at the limiting groove 69, the upper end of the limiting frame 68 is inserted into the limiting groove 69, completing the engagement. When it is necessary to remove the insert 62 from the slot, first move the moving plate 61 with the second fixing frame 66 inward, then move the moving plate 61 on the adjacent side inward, then release the first moving plate 61, and continue to move the other moving plate 61 inward, and so on. Finally, push the pressing plate 63 inward, and the inner end of the pressing plate 63 presses the limiting frame 68 outward, thereby moving the limiting frame 68 away from the limiting groove 69, so that the insert 62 can be pulled out. After that, the lower box 1 and the upper box 2 can also be automatically separated, which is convenient and quick.

[0033] In another embodiment of the present invention, the sealing mechanism 7 includes a rotating column 71 rotatably disposed within the lower housing 1, and a first gear 75 rotatably disposed within the lower housing 1 is fixedly connected to the bottom end of the rotating column 71. A locking assembly 76 is provided on the rotating column 71. One side of the first gear 75 is meshed with another first gear 75, and one side of the other first gear 75 is meshed with a second rack 74 movably inserted into the lower housing 1. The lower end of the second rack 74 extends outside the lower housing 1, and a push rod 77 slidably disposed within the lower housing 1 is fixedly connected to the upper end of the second rack 74. The upper end of the push rod 77 extends to the upper side of the lower housing 1, and a third spring 78 is fixedly connected between the side wall of one end of the push rod 77 and the lower housing 1. A pressure ring 711 is slidably disposed within the upper fixing ring 11 above the silicone pad 72, and a third rack 710 slidably disposed within the upper fixing ring 11 is fixedly connected to the upper end of the pressure ring 711. The third rack 710 has a first rack 73 that is movably inserted into the upper box 2 on one side, and a second gear 79 that is rotatably disposed in the upper box 2 is meshed between the third rack 710 and the first rack 73. A fourth spring 712 is fixedly connected between one end of the first rack 73 and the upper box 2. The lower end of the first rack 73 extends to the lower side of the upper box 2. The locking assembly 76 includes a shaped block that is movably inserted into the outer wall of the rotating column 71. 761, a fifth spring 762 is fixedly connected between the inner end of the irregular block 761 and the rotating column 71. A slot 763 is opened at the lower end of the irregular block 761. A circular groove 764 is opened at the lower end of the upper box 2. A rotating groove 765 is opened on the upper side of the circular groove 764 inside the upper box 2. An inclined surface 766 is opened inside the upper box 2 in the rotating groove 765, and the inclined surface 766 is located directly above the irregular block 761. The pressure ring 711 and the silicone pad 72 have the same shape and structure.

[0034] Specifically, the rotating post 71 is placed in the circular groove 764 at the lower end of the upper box 2. When the rotating post 71 is inserted into the circular groove 764, the irregular block 761 is pressed inward. When the irregular block 761 moves to the inclined surface 766, it will pop outward, which can pre-connect the lower box 1 and the upper box 2, so that the lower box 1 and the upper box 2 can be moved together to the mounting base 3 to prevent the lower box 1 and the upper box 2 from separating. Then, the insert post 62 is inserted into the slot at the upper end of the mounting base 3, and the upper end of the mounting base 3 presses the second straight rack 74 upward. The transmission of rack 74, first gear 75, rotating column 71 and irregular block 761 causes irregular block 761 to move away from inclined surface 766, so the slot 763 will be stuck by the side wall of rotating slot 765, automatically connecting the lower box 1 and the upper box 2. At the same time, through the transmission of second straight rack 74, push rod 77, first straight rack 73, second gear 79, third straight rack 710 and pressure ring 711, the pressure ring 711 moves downward, pressing the silicone pad 72 downward, so that the silicone pad 72 is more tightly attached to the upper surface of the lower fixing ring 9, and the waterproof performance is better.

[0035] In another embodiment of the present invention, the fixing mechanism 8 includes a clamping plate 81 slidably disposed on the inner side of the bottom end of the lower box 1, clamping plates 81 are disposed on both sides of the sub-line 5, a trapezoidal block 82 slidably disposed in the lower box 1 is fixedly connected to one end of the clamping plate 81, and a sixth spring 83 is fixedly connected between the side wall of one end of the trapezoidal block 82 and the lower box 1, and a pressing rod 84 is fixedly connected to the lower side wall of the upper box 2, and the pressing rod 84 is located directly above the higher end of the trapezoidal block 82.

[0036] Specifically, when in use, first fix the mounting base 3 at the installation location, then snap the busbar 4 and the sub-line 5 into the wire clamping groove 10 in sequence, and place the sub-line 5 between the two clamping plates 81. Then place the upper box 2 on the lower box 1. The squeezing rod 84 will squeeze the trapezoidal block 82 inward, thereby clamping the sub-line 5 with the clamping plates 81 to prevent shaking and unstable connection.

[0037] Working principle: When in use, first fix the mounting base 3 at the installation location, then sequentially snap the busbar 4 and the sub-line 5 into the clamping groove 10, and place the sub-line 5 between the two clamping plates 81. Then place the upper box 2 on the lower box 1. The pressing rod 84 will press the trapezoidal block 82 inward, thereby clamping the sub-line 5 with the clamping plates 81 to prevent shaking and unstable connection. Place the rotating post 71 into the circular groove 764 opened at the lower end of the upper box 2. When the rotating post 71 is inserted into the circular groove 764, the irregular block 761 is pressed inward. After moving to the inclined plane 766, it will pop outward, allowing the lower box 1 and upper box 2 to be pre-connected. This facilitates moving the lower box 1 and upper box 2 together to the mounting base 3, preventing them from separating. Then, the insert pin 62 is inserted into the slot at the upper end of the mounting base 3. The upper end of the mounting base 3 then pushes the second spur rack 74 upward. Through the transmission of the second spur rack 74, the first gear 75, the rotating pin 71, and the irregular block 761, the irregular block 761 is moved away from the inclined plane 766. The slot 763 will then be stuck by the side wall of the rotating slot 765. The lower box 1 and the upper box 2 are automatically connected. Simultaneously, through the transmission of the second rack 74, push rod 77, first rack 73, second gear 79, third rack 710, and pressure ring 711, the pressure ring 711 moves downwards, pressing the silicone pad 72 downwards. This ensures the silicone pad 72 adheres more tightly to the upper surface of the lower fixing ring 9, resulting in better waterproofing. When the insert 62 is inserted into the slot, the bottom end of the insert 62 pushes the limiting frame 68 outwards. When the upper end of the limiting frame 68 is located at the limiting groove 69, the upper end of the limiting frame 68 is inserted into the limiting groove. Within 69, the snap-fit ​​is completed. When it is necessary to remove the insert 62 from the slot, first move the movable plate 61 with the second fixing bracket 66 fixed inward, then move the movable plate 61 on the adjacent side inward, then release the first movable plate 61, and continue to move the other movable plate 61 inward, and so on. Finally, push the pressing plate 63 inward, and the inner end of the pressing plate 63 presses the limiting bracket 68 outward, so that the limiting bracket 68 is away from the limiting slot 69, so that the insert 62 can be pulled out. After that, the lower box 1 and the upper box 2 can also be automatically separated, which is convenient and quick.
