Embodiment Construction

[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 The rainproof sealing connection structure of the outdoor distribution box of the present invention shown can be widely used in various types of outdoor distribution cabinets. The rainproof sealing connection structure is between the box door 1 and the door frame 2 on the front of the box body. formed between. The peripheral edge of the box door 1 is vertically extended toward the inside with a rib 3, and the inner side of the rib 3 is provided with a semi-cylindrical boss 4 along the length direction. The boss 4 can be formed by curling the edge of the rib 3 toward the inside. It is also possible to form an integrated structure by means of gluing, welding, etc., between individual components and the rib 3 . The peripheral edge of the seam of the door frame body 2 extends vertically toward the outside, and a seam flange 5 loca...

Abstract

The invention discloses a rainproof sealing connection structure of an outdoor power distribution box. A flange is arranged on the peripheral edge of a box door in a manner of vertically extending towards the inner side, wherein the inner side surface of the flange is provided with an half-cylinder boss along the length direction; a rabbet folded edge which is located at the inner side of the flange and is fastened to the flange is arranged on the peripheral edge of a rabbet of a door frame body in a manner of vertically extending towards the outer side; a water swelling rubber sealing strip comprises an air-tight clamping part and an air-tight leak-proof part; the front end of the air-tight clamping part is provided with a left clamping leg and a right clamping leg for clamping the rabbet folded edge; the front end surface of the air-tight leak-proof part is hermetically attached to the surface of the door frame body; a concave surface jogged with the boss is arranged on the outer side surface of the air-tight leak-proof part; and a plurality of sealing ribs are arranged on the concave surface at intervals. The connection structure of the box door and the door frame body is optimized, and the sealing strip with high rainproof performance is embedded between the box door and the door frame body, so that the rainproof sealing connection structure has the rainproof performance with a high protection grade.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a rainproof sealing connection structure of an outdoor distribution box. Background technique [0002] The distribution box is a centralized assembly of switchgear, measuring instruments, protective appliances and auxiliary equipment in the box according to the requirements of electrical wiring, to carry out controllable power distribution operations for electrical equipment, and to protect the short circuit, overload and leakage of the line. effect. With the development of communication technology, the low-voltage intelligent power distribution cabinet is equipped with a low-voltage power distribution system with network communication capabilities, with automatic detection of operating status and power parameters, automatic control and automatic fault emergency handling capabilities, suitable for application in power plants, substations In other places, monitor...
