Description

Technical Field

[0001] This utility model belongs to the field of outdoor cable wiring technology, and more specifically, it relates to a waterproof sealing and fastening device for cable joints. Background Technology

[0002] Waterproof junction boxes are sealing and protective devices used for waterproofing, dustproofing, and corrosion protection of cable joints. They are usually made of weather-resistant materials such as ABS, PC, and aluminum alloy. The box body and cover are equipped with rubber or silicone sealing rings. Through tight sealing, they can effectively prevent rainwater, moisture, dust, and external impurities from entering. They are widely used in outdoor lighting, security monitoring, power distribution, industrial automation, and other scenarios to ensure the electrical connection safety and stability of cable joints in complex environments. They are mostly composed of a box body, a cover, fixing bolts, and a cable inlet.

[0003] Existing application number: CN201620065267.3, this utility model discloses a waterproof junction box. The bottom of the box is fixed with a base, and the top of the box is fitted with a cover via connecting screws. Knockout holes are formed on all four outer walls of the box, and mounting holes are formed at the four corners of the base. A waterproof connector is inserted into the inner cavity of each knockout hole, and a hexagonal bolt is fitted onto the outer wall of the waterproof connector. A terminal block is fixed to the bottom of the inner cavity of the box. A sealing component is provided at the connection end between the box and the cover. The sealing component includes a sealing frame, a sealing support fitted at the bottom of the sealing frame, a square sealing gasket fitted onto the outer wall of the sealing support, and a sealing gasket fitted onto the outer wall of the waterproof connector. The inner cavity of the box has a sealing groove that mates with the sealing gasket, and a sealing baffle fitted onto the end of the waterproof connector. This waterproof junction box has a simple structure, strong practicality, and improves the sealing and waterproof performance of the junction box.

[0004] Based on the above, when workers use fixing bolts to tighten the cover and body of the waterproof junction box in high-altitude operation scenarios, they need to repeatedly adjust the relative positions of the box body and the cover to accurately align the bolt holes. After the holes are aligned, they need to hold the fixing bolt in one hand and the screwdriver in the other hand to complete the tightening action. Due to the limited space and poor operation stability in high-altitude operations, the operation is extremely difficult for a single person. In addition, the fixing bolt is prone to fall from the height due to uncoordinated hand movements or accidental contact. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a waterproof sealing and fastening device for cable connectors. This solves the problem that in existing high-altitude operations, when workers use fixing bolts to fasten the cover and body of a waterproof junction box, they must first repeatedly adjust the relative positions of the box body and cover to accurately align the bolt holes. After aligning the holes, they still need to hold the fixing bolt in one hand and a screwdriver in the other to complete the tightening action. Due to the limited space and poor operational stability at heights, single-person operation is extremely difficult, and the fixing bolt is prone to falling from a height due to uncoordinated hand movements or accidental contact.

The quick positioning component is located inside and on the right side of the junction box body. The space partition component is located inside the junction box body.

[0008] Furthermore, the quick positioning component includes: a sealing gasket, a plug box, and a mating part; the sealing gasket is fixedly connected to the front of the junction box body; the plug box is fixedly connected to the rear right end of the connecting piece; and the mating part is fixedly connected to the right side of the junction box body.

[0009] Furthermore, the quick positioning component also includes: a sliding plate and a pressing button; the sliding plate is slidably connected inside the plug box; the pressing button is fixedly connected below the sliding plate.

[0010] Furthermore, the quick positioning component also includes: a triangular positioning block and a return spring; the triangular positioning block is fixedly connected to the lower part of the sliding plate; the lower end of the return spring is fixedly connected to the upper part of the sliding plate, and the upper end of the return spring is fixedly connected to the inside of the plug box.

[0011] Furthermore, the space separation component includes: a docking groove, a docking plate, and a U-shaped block; two docking grooves are provided, and the two docking grooves are respectively provided inside the two separation plates; two docking plates are provided, and the two docking plates are respectively inserted into the two docking grooves; the U-shaped block is fixedly connected to the front of the two docking plates.

[0012] Furthermore, the space separation component also includes: a fixed magnet and a mating magnet; two fixed magnets are provided, and the two fixed magnets are respectively fixedly connected inside the two docking slots; two mating magnets are provided, and the rear end of the U-shaped block is fixedly connected to the two mating magnets.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, by setting up a quick positioning component, the plug box can be inserted into the mating part before installing the fixing bolts, which can achieve the initial fixing of the sealing cover and the box body and the precise alignment of the bolt holes without repeated adjustments. When installing the fixing bolts, there is no need to hold the sealing cover by hand, which reduces the installation difficulty for a single person in complex scenarios such as high altitudes and improves installation efficiency and operational safety.

[0015] Secondly, by setting up partition plates and pluggable docking plates, the interior of the junction box can be divided into multiple independent spaces, allowing different types of cables to be placed separately to avoid mutual interference. Furthermore, the attraction between the fixing magnet and the cooperating magnet prevents the docking plates from easily falling off, ensuring the stability of the partition structure. This not only improves the regularity of the cable layout inside the box but also makes it easier to find the target cable during subsequent maintenance, reducing the difficulty of maintenance.

[0016] This utility model achieves initial fixation of the sealing cover and the box body and precise alignment of bolt holes by setting up a quick positioning component, reducing the installation difficulty in scenarios such as high altitudes for single personnel, improving installation efficiency and safety, and dividing the internal space of the junction box body to classify and place multiple cables, ensuring the neatness of the cable layout and facilitating subsequent maintenance. It adapts to the complex installation and maintenance needs in outdoor cable wiring scenarios and provides a more reliable and efficient solution for cable joint protection in high-altitude and other working conditions.
