Air compressor junction box of good sealing performance

Abstract

The present invention belongs to the air compressor structure technology field, in particular to an air compressor junction box of good sealing performance. The air compressor junction box comprises abox body and a box cover, a groove is arranged in the circumferential direction of the outer edge of the box cover, and a flange of the box body is arranged in the groove cooperatively. A gasket is clamped between the flange of the box body and the groove, the box cover, the gasket and the box body are assembled as one via the bolts, and a dovetail groove is arranged in the annular direction of the gasket. A dovetail protrusion is arranged on the flange of the box body, the dovetail groove and the dovetail protrusion cooperate with each other, and a Y-shaped lip is arranged on one end face ofthe gasket far away from the dovetail groove annularly. The two lip edges of the Y-shaped lip are attached to the groove walls of the groove, and a protruding tooth is fixed at the bottom of the groove and is pressed in the Y-shaped lip. The beneficial effects of the present invention are that by adopting the bolts to connect, the overhauling is convenient; a sealing surface of the flange of thebox body and the walls of the groove of the box cover are together attached to the gasket separately and always, so that a gap is not generated, the waterproof and dustproof performances are good, aninternal circuit in the box body is not in short circuit and is not burnt out, 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...

Problems solved by technology

[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 operation of the air compressor and shortens the service life of the air compressor
