WATERPROOF CONNECTOR

摘要

A waterproof connector (10) includes a female housing (30) formed with cavities (31), and female terminals (20) connected to ends of wires (W) are inserted into the cavities (31) from behind. Shorting terminals (50) are accommodated in terminal accommodating portions (40) in a front part of the housing (30) to short adjacent female terminals (20). A one-piece rubber plug (60) is fit into a rear part of the housing (30) and includes through holes (62) through which the wires (W) are to be inserted. A rear holder (70) is mounted into the housing (30) to retain the one-piece rubber plug (60). Recesses (65) are provided on the one-piece rubber plug (60) in areas behind the terminal accommodating portions (40). Compressing protrusions (75) project from the rear holder (70) and are press-fit into the recesses (65) from behind.

主权项

1. A waterproof connector, comprising:
terminal fittings to be connected to ends of wires; a housing formed with a plurality of cavities arranged side by side and configured such that the wires are accommodated therein from behind together with the terminal fittings; terminal accommodating portions provided along an arrangement direction of the plurality of terminal fittings in a front end part of the housing and configured to accommodate shorting terminals for shorting the plurality of terminal fittings; a seal to be fitted into the housing from behind and including a plurality of through holes provided side by side to correspond to the cavities and configured such that the wires are inserted therethrough; a rear holder held in the housing while being fit behind the seal in the housing and configured to retain the seal; a plurality of recesses provided along an arrangement direction of the through holes on the seal and arranged behind laterally long terminal accommodation areas in the housing where the plurality of terminal accommodating portions are formed; and a plurality of compressing protrusions projecting from the rear holder and configured to press the seal in directions to reduce the through holes in diameter by being press-fitted into the recesses from behind; wherein: a length of a part of the rear holder to be matched with and fitted into the housing in a connecting direction is set longer than a projecting distance of the press-fitting protrusions; and the recess has a plurality of inner surfaces and a compressive lip is provided on the surface adjacent to the through hole out of the plurality of inner surfaces.
