Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a junction box that is easy to install. Background Art

[0002] In home decoration, the junction box is one of the electrical auxiliary materials, because the wires used for decoration pass through the wire conduit, and the junction box is used as a transition at the joint of the wires (for example, the line is relatively long, or the wire conduit needs to turn a corner). The wire conduit is connected to the junction box, and the wires in the wire conduit are connected in the junction box, which plays a role in protecting and connecting the wires.

[0003] The existing junction box usually needs to be installed on a wall or in a distribution box, and the wires are inserted into the junction box from the wire tube and connected to the wiring terminals. Then another wire is inserted into the junction box from another wire tube and connected to the wiring terminals so that the wires can be transferred. However, when installing the junction box, the junction box is usually mounted on the wall or in the distribution box by bolts. When it needs to be disassembled for maintenance, the bolts of the junction box need to be loosened and disassembled, and it needs to be installed again with bolts after the maintenance is completed. At the same time, the installation port of the junction box needs to be aligned with the installation port of the wall or the distribution box each time it is installed, which makes the installation after each maintenance very troublesome, so it needs to be improved.

When the locking nut 15 is in place, the locking nut 15 is engaged with the locking nut 16 and the locking nut 16 is engaged with the locking nut 16. When the locking nut 15 is in place, the locking nut 15 is engaged with the locking nut 16 and the locking nut 16 is engaged with the locking nut 16.

[0029] like Figure 1-2 As shown, the protective component includes a sealing gasket 5 and a cover plate 4. The four ends of the front side of the cover plate 4 are respectively penetrated with openings, and the openings correspond one-to-one to the threaded holes on the front side of the junction box 1. The sealing gasket 5 is fixedly installed on the outer edge of the opening of the junction box 1, and the four ends of the front side of the sealing gasket 5 are penetrated with openings. The cover plate 4 is fixedly connected to the opening of the junction box 1 by screws.

[0030] By providing the sealing gasket 5 and the cover plate 4, the opening of the junction box 1 can be covered by the cover plate 4 so that the cover plate 4 can protect the connection terminals 3 and wires inside the junction box 1, and the sealing gasket 5 increases the sealing between the cover plate 4 and the junction box 1, further increasing the protection effect.

[0031] like Figure 2-3As shown, the fixing assembly includes a mounting frame 9, a threaded barrel 10, a screw 11 and a knob 12. The mounting frame 9 is fixedly mounted on the two ends of the front of the mounting seat 6 respectively. A mounting port is provided through the side of the mounting frame 9, and a threaded barrel 10 is fixedly mounted on the inner wall of the mounting port. The inner wall of the threaded barrel 10 is threadedly connected with a screw 11. A knob 12 is fixedly mounted on one end of the screw 11. A fixing auxiliary assembly is provided on the other end of the screw 11. The fixing auxiliary assembly includes a mounting plate 15, a telescopic rod 16 and abutment plate 18. A shaft seat is sleeved on one end of the screw 11, and a mounting plate 1 is fixedly connected to the side of the shaft seat. 5. A telescopic rod 16 is fixedly installed on the side of the mounting plate 15, and a stop plate 18 is fixedly installed on one end of the telescopic rod 16. Limiting components are arranged on the side of the mounting plate 15 and the two sides of the mounting frame 9. The limiting components include a limiting column 14 and a limiting plate 13. The limiting columns 14 are fixedly installed on both ends of the side of the mounting plate 15, and the limiting plates 13 are fixedly installed on the two sides of the mounting frame 9. Holes are penetrated on the side of the limiting plate 13, and the limiting columns 14 pass through the holes of the limiting plate 13. A plurality of card slots 19 are opened on both sides of the junction box 1, and the card slots 19 fit with the stop plate 18.

[0032] By means of the mounting frame 9, threaded barrel 10, screw 11, knob 12, mounting plate 15, telescopic rod 16, stop plate 18, limit column 14, limit plate 13 and slot 19, the mounting base 6 is mounted on a wall or inside a distribution box, and then the card plate 8 is inserted into the slide slot 7. By rotating the knob 12 to rotate the screw 11 in the threaded barrel 10, the stop plate 18 can be inserted into the slot 19 to fix the junction box 1. When the stop plate 18 is inserted into the slot 19, since the limit column 14 passes through the hole of the limit plate 13, the mounting plate 15 will not rotate when the screw 11 rotates.

[0033] like Figure 4 As shown, a spring 17 is fixedly connected to the side of the abutment plate 18 , and the other end of the spring 17 is fixedly connected to the side of the mounting plate 15 , and the spring 17 covers the telescopic rod 16 .

[0034] By setting the spring 17, when the plate 18 is inserted into the slot 19, the telescopic rod 16 can be contracted, and the spring 17 will be compressed and deformed, so that the rotating screw 11 will encounter a certain resistance, thereby preventing the plate 18 from damaging the surface of the junction box 1 due to over-tightening.

[0035] Working principle: During the first installation, the mounting base 6 is installed on the wall or inside the distribution box, and then the card plate 8 is inserted into the slide groove 7, and the screw 11 is rotated in the threaded tube 10 by rotating the knob 12 to drive the plate 18 to be inserted into the slot 19 to fix the junction box 1, and when the plate 18 is inserted into the slot 19, the telescopic rod 16 can be contracted, and the spring 17 will be compressed and deformed, so that the rotation of the screw 11 is subject to a certain resistance. Since the limit column 14 passes through the hole of the limit plate 13, the mounting plate 15 will not rotate together when the screw 11 rotates, and then the wires are inserted from different wire tubes 2 respectively so that they are all connected to the wiring terminals 3. After completion, the cover plate 4 is fixedly connected to the front opening of the junction box 1 by screws to complete the installation. When disassembly is required, the knob 12 is rotated so that the plate 18 can no longer resist the slot 19, so that the card plate 8 can be pulled out from the slide groove 7. When installing again, only the card plate 8 needs to be inserted into the slide groove 7 and the plate 18 can be inserted into the slot 19.
