Problems solved by technology

Although the long side wall can suppress the contact pressure with the lip side by itself flexing and deforming, it is difficult to set the contact pressure with the lip side because the short side wall is not easy to flex and deform. Small
Therefore, on the short side wall, the deflection of the lip may be larger than that of the long side wall, and the bite of the total rubber stopper may easily occur.

Embodiment Construction

[0019] Preferred embodiments of the present invention are shown below.

[0020] The cover-side exit portion is disposed at a position away from the lip when the cover is fitted to the housing. According to this structure, in the state where the cover is fitted outside the housing, the part of the opening end of the cover other than the cover-side exit part is in close contact with the lip, so the adhesion force between the cover and the lip is increased, and it is possible to reliably To maintain the specified tightness.

[0021]

[0022] Below, based on Figure 1-Figure 8 Examples of the present invention will be described.

[0023] The waterproof connector involved in this embodiment is as figure 1 As shown, it is provided with: a plurality of terminal fittings 90 made of conductive metal; a housing 70 made of synthetic resin, which can accommodate each terminal fitting 90; a total rubber plug 50 made of rubber, which is arranged at the rear end of the housing 70; Rear...

Abstract

A one-piece rubber plug (50) is arranged on a rear end part of a housing (70) and a rear holder (30) to be locked to the housing (70) is arranged behind the rubber plug (50). A receptacle (10) is fit externally to the housing (70) from front and an opening end part of the receptacle (10) is held in close contact with lips (55) of the rubber plug (50). The receptacle (10) includes short side walls (15) that face each other in a first direction and long side walls (14) that face each other in a second direction. Receptacle-side escaping portions (19) retracted more in a front-back direction than inner peripheries of opening end parts of the long side walls (14) are provided on inner peripheries of opening end parts of the short side walls (15).

Description

technical field [0001] The present invention relates to waterproof connectors. Background technique [0002] The waterproof connector disclosed in Patent Document 1 includes: a housing for accommodating terminal fittings; a total rubber plug disposed at the rear end of the housing and having a sealing hole through which electric wires connected to the terminal fittings are inserted in a liquid-tight manner; The holding body (rear holding body), which is arranged behind the total rubber plug, the rubber plug holding body is locked with the housing, and the total rubber plug is clamped between the rubber plug holding body and the housing; and a cover-shaped cover, It fits outside the housing from the front. A busbar body integrating the busbar and the holder is attached to the front end of the case. When the busbar body is assembled to the housing, the terminal fittings are connected with the busbars and short-circuited in a prescribed pattern. After assembling the bus bar ...
