Occluder device for power distribution box and using method thereof

Abstract

The invention discloses a occluder device for power distribution box, comprising: a rubber occluding member; a upper pressing force pressing plate; a lower pressing force pressing plate, and several bolts for connecting the upper pressing force pressing plate and the lower pressing force pressing plate together to deform the rubber occluding member; the upper pressing force pressing plate and thelower pressing force pressing plate are connected together to form a ring structure by two half pressing plates, a rim edge is provided on the outside upper end of the upper pressing force pressing plate; the rubber occluding member, the upper pressing force pressing plate and the lower pressing force pressing plate pass through the inlet and outlet holes of the power distribution box body, the rim edge is stuck on the outside of the power distribution box body. According to the occluder device for power distribution box, the invention has the advantages as follows: The rim edge is provided, the occluder device passes though the inlet and outlet holes, the rim edge is stuck on the outside of the power distribution box body, so that the sealing performance between the pressing plates and the box body is good, the nut cannot resist the box body during pressing, and cannot damage to the box body; the rubber layer is provided, so that the sealing performance between the pressing plates andthe box body is improved more; and dislocations do not occur.

Description

technical field [0001] The invention relates to an obturator used for a distribution box and a method for using the same, belonging to the technical field of electric equipment. Background technique [0002] In construction sites, factories, roadsides and other occasions, the distribution box is an indispensable equipment in the electric power link. When decorating homes, studios, and offices, distribution boxes are often used. The switchgear, measuring instruments, protective appliances and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements to form a power distribution device. Therefore, in the manufacturing process, it is necessary to reserve the entry and exit through which the power supply line passes. Wire holes, there will be gaps between the inlet and outlet wire holes and the wires during use. If they are not blocked, the distribution box will not be sealed, water, silt, dust, de...

Problems solved by technology

[0002] On construction sites, factories, roadsides and other occasions, the distribution box is an indispensable device in the power link. When the home, studio, and office are decorated, the distribution box is often used. As we all know, the distribution box is According to the electrical wiring requirements, the switchgear, measuring instrument, protective device and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on a screen width to form a power distribution device, so it is necessary to reserve the entrance and exit of the power supply line during the manufacturing process. Wire hole, there will be a gap between the wire hole and the wire during use. If it is not blocked, the distribution box will not have airtightness, water, mud, dust, sundries, mice and small animals etc. will enter the distribution box, which will cause damage to the switchgear, measuring instruments, protective appliances and auxiliary equipment in the distribution box, and reduce the service life of the distribution box, especially in bad weather such as rainy and heavy snow. The damage is even more serious. Chinese patent 201720133805.2 discloses a sealing device for cabinets. The flexible seal is in the shape of a torus and the outer peripheral surface is curved and concave in the direction of the axis. In addition, the diamond-shaped blind holes evenly distributed on the flexible seal are outer large The inner small structure, so the deformation in the direction of the axis during installation can be 2-3 times larger than the existing device, which can ensure a stable and reliable seal when installing various cables. Sealing, but the various nuts between the annular pressure plate and the box body of the electric control cabinet make the sealing between the annular pressure plate and the box body poor. damage, and the blocking device needs to be installed inside the box, so the bolts are also inside the box, and it is very inconvenient when the rotating bolt squeezes the flexible seal to deform
