Connector having male and female terminal housings
View Patent ↗A connector includes: a female terminal housing provided with a terminal receiving cavity receiving a female terminal; and a male terminal housing retaining a male terminal to be connected to the female terminal. The male and female terminal housings have first and second engagement portions. The male and female terminal housings are fitted in a first fitting position by the first engagement portion. The male and female terminal housings are fitted in a second fitting position by the second engagement portion. The first fitting position is a position in which the locking hole of the female terminal is engaged with the lance of the terminal receiving cavity, and in which the male terminal is not in sliding contact with the female terminal. The second fitting position is a position in which the male terminal is in sliding contact with the female terminal.
1. A connector comprising:
a female terminal housing provided with a terminal receiving cavity configured to receive a female terminal; and a male terminal housing configured to retain a male terminal to be connected to the female terminal, wherein a lance made of a resilient member and formed on an inner wall of the terminal receiving cavity is engaged with a locking hole formed in a tubular portion having a resiliently deformable contact member therein of the female terminal, and the male terminal housing and the female terminal housing are fitted to each other to allow the male terminal to be in sliding contact with the contact member of the female terminal, wherein:
the male terminal is insert-molded to the male terminal housing;
the male terminal housing and the female terminal housing have a first engagement portion and a second engagement portion;
the male terminal housing and the female terminal housing are fitted to each other in a first fitting position by the first engagement portion;
the male terminal housing and the female terminal housing are fitted to each other in a second fitting position by the second engagement portion;
the first fitting position is a position in which the locking hole of the female terminal is engaged with the lance, and in which the male terminal is not in sliding contact with the contact member of the female terminal;
the second fitting position is a position in which the male terminal is in sliding contact with the contact member of the female terminal;
the first engagement portion includes: a first arm provided on a first surface of the male terminal housing and formed with a first groove; and a first protrusion protruding from a first surface of the female terminal housing and corresponding to the first groove of the first arm;
the second engagement portion includes: a second arm provided on a surface of the male terminal housing and formed with a second groove; and a second protrusion protruding from a second surface of the female terminal housing and corresponding to the second groove of the second arm;
in the first position, the first protrusion is engaged with the first groove of the first arm, and a leading end of the second arm abuts against the second protrusion; and
in the second fitting position, the second protrusion is engaged with the second groove of the second arm.
2. The connector according to claim 1 , wherein one of the male terminal housing and the female terminal housing is provided with a hole which is elongated in a fitting direction and which has a cross section of an L-shape, and the other of the male terminal housing and the female terminal housing is provided with a member which protrudes therefrom to fit into the hole and which has a cross section of an L-shape.
3. The connector according to claim 1 , wherein one of a leading end of male terminal housing and a leading end of the female terminal housing is provided with at least two guide ribs which are extended toward the other of the male terminal housing and the female terminal housing, and the other of the male terminal housing and the female terminal housing is provided with at least one of guide grooves and guide tubes to which the two guide ribs are fitted.
