Abstract: An electric connector includes an electrically insulative housing, and a terminal having an engagement section and inserted into a terminal space formed in the housing in a direction from a rear towards a front of the housing. The housing includes a lance protruding in the housing towards an axis of the terminal space, and is able to engage to and disengage from the engagement section of the terminal. A resilient support resiliently supports the lance such that the lance is able to move away from the axis, and a path is provided through which a jig for disengaging the lance from the engagement section is inserted into the housing through a front of the housing towards the lance along the engagement section. The resilient support is formed with a slit communicating with the path and extending towards the lance from an entrance of the path.

Abstract: An electric connector includes a first housing including a first wall, second and third walls both extending in parallel from the first wall, and a fourth wall connecting the second and third walls to each other, the first to fourth walls defining an inner space in the first housing, and a second housing to be fit into the inner space, the first housing including a first projection protruding into the inner space from an inner surface of the first wall, and a first recess formed at the second and third walls, the second housing including a second recess through which the first projection is guided, a wall to make abutment with the first projection when the second housing is inserted in an upside-down posture into the inner space, and a second projection to be fit into the first recess.

Abstract: A connector terminal includes a hollow sheath portion to be inserted into a terminal space formed in a housing of an electric connector, and an elastic contact piece positioned in the sheath portion, the contact piece making mechanical and electrical contact with a male terminal of an opponent electric terminal when the male terminal is inserted into the sheath portion, the male terminal being inserted into the sheath portion through an insertion path formed in the housing, the sheath portion being formed with a projection on at least one of inner walls thereof facing each other, the projection introducing a distal end of the contact piece to be located out of a cross-section of the insertion path in a direction perpendicular to a direction in which the male terminal is inserted into the sheath portion.

Abstract: A lock arm formed on a second housing fit into a first housing including a lock unit, includes an elastically deformable lock arm body, first and second legs connecting the lock arm body to the second housing with a gap therebetween, a lock portion to be locked to the lock unit, and an extension obliquely extending from the lock arm body, wherein when the extension is pushed towards the lock arm body, the lock arm body is deformed, then, the extension makes contact with the lock arm body, and then, the lock arm body is deformed with the first and second legs acting as fulcrums and further with an abutment point acting as a working point to thereby allow the lock portion to be released from the lock unit, the extension and the lock arm body making contact with each other at the abutment point.

Abstract: The electric connector includes a housing having cavities partitioned by partition walls, a terminal being inserted into each of the cavities, the housing being formed with at least one retainer insertion hole formed through a sidewall of the housing and the partition walls in a second direction perpendicular to a first direction in which the terminal is inserted into each of the cavities, and a retainer inserted into the retainer insertion hole to be engaged with the terminal in the housing, the retainer including a surface with which the retainer makes contact with the retainer insertion hole, and at least one projection formed on the surface, the projection passing over at least one partition wall and being engaged with a particular partition wall, the projection being elastically deformable in the first direction.
