Abstract: A lock portion for a connector which is adapted to disengageably lock connector housings which are adapted to be engaged with each other by locking an engaging portion provided on the male housing with a latch portion provided on the female housing, characterized in that flexible lock arms which are fixed on a horizontal wall of the female housing so as to extend in an engaging direction includes the latch portion at an opposite side, and a disengaging lever portion which is connected at its one end to the latch portion so as to extend along the lock arms, and which rotates with the latch portion around a support portion which is abutted movably against the horizontal wall by pushing a finger touch portion for lock disengaging operation in a backward end, whereby a locked condition will be disengaged.

Abstract: A connector housing has an abutment surface with which a front end surface of an opposing connector is brought into contact at a time of fitting to the opposing connector. Terminal metal fittings are inserted to positions rearward from the abutment surface from terminal insertion holes in the connector housing. A retainer is moved to a regular engagement position from a temporary engagement position so as to prevent the terminal metal fittings from falling off rearward, and is provided with a projection extending forward from the abutment surface of the connector housing.

Abstract: In a waterproof connector 1 of the present invention, female terminals 4, each having a box-like electrical contact portion 5, are received respectively in terminal receiving chambers 3 in a housing 2, and a mat seal 6, having a plurality of wire-sealing insertion holes 7, is provided at rear ends of the terminal receiving chambers 3. The box-like electrical contact portion 5 of a square cross-sectional shape is formed into such a modified polygonal cross-sectional shape that one of a pair of opposed sides of the square cross-sectional shape is smaller in length than the other. A mat seal cover 13, cooperating with the housing 2 to hold the mat seal 6 therebetween, has a plurality of terminal insertion holes 14, and the terminal insertion hole 14 has a shape which is analogous to and slightly larger than the modified polygonal cross-sectional shape.

Abstract: A terminal provided with a contact surface to be brought into contact with a mating terminal. In order to improve the strength of the contact surface, the terminal is constructed so that an elastic contact leaf is provided inside a square cylindrical contact portion into which a mating terminal is inserted and that the contact surface expanding in the direction of the elastic contact leaf is formed in a wall portion opposite to the elastic contact leaf in the contact portion. The contact surface is formed into a plane shape where the length of the central portion is set to be greater than the length of both sides in the direction of inserting the mating terminal.

Abstract: A terminal with a locking member capable of surely preventing damage of the locking member even in case the terminal inserted and locked in a connector housing is pulled reversely. An electric contact portion of the terminal has a cantilever-like locking member and protection walls for the locking member thereby to engage the locking member with a locking step of the connector housing, and further engaging-arm portions are provided on the locking member and arm-engaged portions engaging with the engaging-arm portions are also provided on the protection walls.
