Description
Technical Field
The utility model relates to a group especially relates to a waterproof group.
Background
The wire and the plug connector form a wire group, the traditional wire group has unreasonable structural design of the plug connector, poor sealing performance of the plug connector and weak waterproofness, so that the wire and the plug connector cannot be used in an environment with requirements on waterproofness, and the application range of a product is narrow.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a waterproof wire group with reasonable structural design, good waterproof performance and wide application range.
A waterproof wire set comprises a wire and a plug connector, wherein the plug connector comprises a plastic surface cover, a conductive plug terminal, a first sealing ring, a plastic main body, a second sealing ring, a conical rubber ring and a rear cover; one end of the wire sequentially passes through the rear cover, the conical rubber ring and the plastic main body and is welded on the conductive plug-in terminal, and the conductive plug-in terminal is fixed on the plastic surface cover; the inner wall of the face cover is provided with an annular mounting groove, the first sealing ring is embedded in the annular mounting groove, the outer wall of the middle part of the plastic main body is provided with an annular boss, the face cover is in threaded connection with one end of the plastic main body, the rear cover is in threaded connection with the other end of the plastic main body, and a second sealing ring is sleeved between the annular boss and the rear cover; the one end of plastics main part still is provided with the toper and compresses tightly the piece, the toper compresses tightly the piece and comprises a plurality of regularly arranged elasticity pressure claws, the toper rubber circle is installed in the toper compresses tightly the piece, be equipped with in the back lid and compress tightly the corresponding toper cavity of piece with the toper.
The conductive plug terminals are fixed on the plastic surface cover in a plastic sealing mode, and the number of the conductive plug terminals is two or three.
The conical pressing piece, the annular boss and the plastic main body are integrally formed by injection molding.
The utility model has the advantages that: the conductive plug-in terminal is fixed on the plastic surface cover in a plastic sealing way and is welded and fixed with the wire; the first sealing ring and the second sealing ring effectively seal the joints between the plastic surface cover and the plastic main body and between the rear cover and the plastic main body, so that water is prevented from entering; the conical rubber ring is embedded in the conical pressing piece, when the rear cover is screwed down, the conical cavity of the rear cover presses the conical pressing piece and the conical rubber ring through taper fit, so that the inner wall of the conical rubber ring is tightly attached and sealed with the outer wall of the electric wire, and water inflow is avoided; this product is connected convenient and fast, has better water-proof effects.
