Air compressor junction box of good sealing performance

Abstract

The invention belongs to the technical field of air compressor structure, and specifically relates to an air compressor junction box with good airtightness, which includes a box body and a box cover, grooves are arranged on the outer edge of the box cover, and the flange of the box body is arranged on the In the groove, a gasket is sandwiched between the flange of the box body and the groove; the box cover, the gasket and the box body are assembled into one body by bolts; The dovetail groove and the dovetail protrusion cooperate with each other; the end surface of the gasket away from the dovetail groove is provided with a Y-shaped lip in the circumferential direction, and the two lips of the Y-shaped lip fit on the groove wall of the groove; The groove bottom is fixed with protruding teeth, and the protruding teeth are pressed into the Y-shaped lip. The beneficial effects of the present invention are: the bolt connection is adopted, which is convenient for maintenance; the flange sealing surface of the box body and the groove wall of the box cover are respectively attached to the gasket all the time, without any gap, and the waterproof and dustproof performance is good. It will cause the internal circuit of the box to be short-circuited and burned, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of air compressor structures, and in particular relates to an air compressor junction box with good sealing performance. Background technique [0002] In motor vehicles, in order to make the junction box of the vehicle-mounted air compressor reach IP67, it is generally sealed with glue. The junction box after glue is not removable. Once there is a problem with the line, the cause cannot be checked in time. If the bolt structure is used, the bolts will loosen during the driving of the vehicle, which will cause a gap between the sealing ring and the flange sealing surface; The internal circuit is short-circuited and burned, which affects the work of the air compressor and shortens the service life of the air compressor. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, to provide a bolt connection, which is convenient for maintenance; The a...
