Waterproof connector
A butting surface ( 6 ) is formed on a tip of the receptacle ( 2 ) of a male connector (M), and a smooth sealing surface ( 10 ) is formed on a back side via a tapered surface ( 7, 9 ). A pad ( 5 ) to be butted in a compressed state by the butting surface ( 6 ) when the male connector and a female connector (M, F) are connected is mounted in a back part of a terminal accommodating portion ( 13 ) of the female connector (F). A seal body ( 14 ) separate from the pad ( 5 ) and held in close contact with the sealing surface ( 10 ) in a watertight manner is mounted in front of the pad ( 5 ) in the terminal accommodating portion ( 13 ).
1. A waterproof connector, comprising:
a male connector including a male housing having a male terminal fitting accommodated therein;
a receptacle formed on the male housing and open forward;
a butting surface formed on an opening end surface of the receptacle;
a tapered surface formed in an area of an inner peripheral surface of the receptacle backward of the butting surface and expanded forward;
a sealing surface formed in an area of the inner peripheral surface of the receptacle backward of the tapered surface;
a female connector including a female housing;
a terminal accommodating portion constituting the female housing and configured to accommodate a female terminal fitting;
an outer tube portion constituting the female housing and surrounding the terminal accommodating portions;
a fitting space formed between the terminal accommodating portion and the outer tube portion, open toward a leading end side of the female housing and allowing the receptacle to be fit thereinto;
a pad made of rubber, having an annular shape, constituting the female connector by being mounted in a back part of the terminal accommodating portion and configured to be sandwiched between a back wall of the female housing and the butting surface of the receptacle to be resiliently deformed in a compressed state when the male and female housings are connected;
a plurality of butting projections formed on the pad and configured to be butted against the butting surface of the receptacle when the male and female housings are connected; and
a seal body made of rubber, formed separately from the pad, constituting the female connector by being fit on an outer peripheral surface of the terminal accommodating portion at a position spaced forward from the pad and configured to be held in close contact with the sealing surface of the receptacle in a sealed state when the male and female housings are connected.
2. The waterproof connector of claim 1 , wherein front and back sides of the pad are shaped symmetrically.
3. The waterproof connector of claim 2 , wherein front and back sides of the seal body are shaped symmetrically.
4. The waterproof connector of claim 1 , wherein front and back sides of the seal body are shaped symmetrically.
