Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem of reduced protective performance caused by screw gaps and welding deformation, and to provide a split junction box, so that the product can be applied to occasions with high protection requirements. The present invention includes a sealing strip that can be quickly installed and is not easy to fall off. The sealing strip does not need to be glued, and the installation is quick and reliable. When the specified sealing requirements are met, it can not only provide sealing reliability through double-sided sealing, but also facilitate replacement. You only need to directly replace the sealing strip without other tools. and accessories

Embodiment 1

[0028] Such as figure 1 and 4 As shown, a split junction box includes screws 1, panels 2, U-shaped rubber sealing strips 3, pressing parts and box body 5; box body 5 is provided with a center hole 1, and is evenly distributed on the edge of the center hole. n through-holes, n≥6; if the central hole is a round hole, all the through-holes are evenly distributed along the circumferential direction of the central hole; if the central hole is a square hole, the through-holes are along the length direction of the central hole Arranged equidistantly, also equidistantly arranged along the width direction; the pressing part is an integral structure, with n blind holes provided with internal threads; the central axes of n blind holes and n through holes are aligned One alignment. The overall shape of the U-shaped rubber sealing strip 3 is consistent with the shape of the central hole 1; the end surface of the U-shaped rubber sealing strip 3 is provided with a central hole 2 coaxially ...

Embodiment 2

[0032] Except that the pressing part adopts a split structure, the rest of the structure is exactly the same as that of the first embodiment; the pressing part includes n / 3 pressing blocks 4; each pressing block is provided with 3 blind holes.

Abstract

The invention discloses a split type junction box. An existing split type junction box cannot be applicable to an environment with a high protection grade. According to the split type junction box disclosed by the invention, a channel of a U-shaped rubber sealing strip coats a first central hole of a box body, and a panel compresses the outer end face of the U-shaped rubber sealing strip; a compression part is arranged in the box body and compresses the inner end face of the U-shaped rubber sealing strip; one screw passes through one combination of each third through hole of the panel, a corresponding second through hole of the U-shaped rubber sealing strip and a corresponding first through hole of the box body, which are aligned; the tail part of each screw is connected with a corresponding blind hole of the compression part; and the U-shaped rubber sealing strip comprises a U-shaped rubber matrix and a metal elastic sheet. Due to adoption of a U-shaped structure of the U-shaped rubber sealing strip and a form of the compression part, the split type junction box disclosed by the invention effectively solves a problem that substances such as water or dust and the like can enter thebox body along with thread gaps of the screws.

Description

technical field [0001] The invention belongs to the fields of industrial application and rail transit application, and in particular relates to a split box body. Background technique [0002] The current split box sealing structure mainly has the following two types: 1. One-sided seal, the seal is installed between the panel and the box, the nut is welded on the back of the box, and finally fixed by fasteners; 2. One-sided seal, The seal is installed between the panel and the box body, and the screw sleeve is welded on the back of the box body (the thread does not penetrate the screw sleeve), and finally fixed by the fastener; the above first sealing structure cannot solve the deformation problem caused by welding, and because Weld nuts, water or dust can enter the box along with the screw thread gap, so it is not suitable for environments with higher protection levels; The thread gap enters the box, but it cannot solve the deformation problem caused by welding, which affec...
