A connector housing has a lock arm for locking a terminal therein. The lock arm deflects in an complete insertion state of the terminal so that a spacer abuts against a side surface of the lock arm. The lock arm is formed with a projection which abuts the incompletely inserted terminal in the spacer advancing direction. The projection may be a plate piece elongated in the longitudinal direction of the lock to be pinched by a pair of a resilient contact plates of the terminal. Alternatively, the lock arm may have a protrusion engaging with an engagement hole formed in the connector housing. The protrusion is a rectangular plate extending from the fore end of the lock arm. An inclined guide surface continuous with the engagement hole may be provided in the connector housing. Alternatively, the connector housing may have an inner embossed wall positioned closely to the deflected lock arm to oppose to the spacer. A clearance between the embossed wall and the lock arm is determined within the elastic deflection limit of the lock arm.

Connector structure and assembling method for connectors

A front end portion of the inserted terminal position correcting jig is inserted into an opening formed in a peripheral wall provided extendedly from the rear portion of a connector housing, which opening functioning as its pivot center and having a correcting operation checking member therein, thereby to shift the jig toward the housing pivoting on the opening, and by this operation the jig is fitted with the rear end portion of the terminal which is still in an incompletely inserted state so as to shift the terminal to a completely inserted position and securely locked, wherein since the correcting operation checking member formed in the opening is removed when the front end portion of the jig is inserted, whether or not the correcting operation is perfectly done can be checked from outside by a removal or deformation of the correcting operation checking member.

Terminal insertion and correction jig

A female connector 30 is provided with a reciprocative and slidable slide member 13; an operation lever 20 rotatably coupled to the connector for sliding the slide member 13 within the connector; and a guide groove 14 and a guide pin 44 arranged to be engaged to the slide member 13 and a male connector 40. The operation lever 20 is rotated to introduce the male connector 40 into the female connector 30 so that the two connectors are connected to each other. A projection 27 arranged to be brought into contact with the outer surface of the male connector 40 when the guide groove 14 and the guide pin 44 have incompletely been connected to each other is integrally provided with a side wall 22 of the operation lever 20 so as to prevent rotation of the operation lever 20. Thus, the connector structure will resist breakage and deformation even if excessive force is exerted on the lever when attempting to secure a connection while the male and female connectors are not completely connected.

Structure for connecting connectors

In a chained terminal, plural male terminals each of which is provided with an electric contact part and an electric wire connecting part, are arranged at a predetermined interval on both sides of a feed plate in a staggered layout. A pair of terminal crimping machines are arranged in positions in which they are separated by a pitch between adjacent male terminals on both sides of the feed plate, and an electric wire is alternately crimped and fixed to each male terminal on both sides of the feed plate by each terminal crimping machine, while feeding the chained terminal by the half of the pitch between adjacent male terminals.

Crimping method for producing a chained terminal

Plural sub-connectors (13), where terminal housing chambers (29) for housing terminals (21) are formed, are inserted into a holding member (12). Double engagement members (31), which have engagement claw (33) sections to be engaged with the terminals (21) externally and abutting sections (34) to abut an inner surface of the holding member (12), are provided on an outer wall of the connector housing (22) of the male sub-connectors (13) so as to prevent the terminals (21) from slipping off.

A male terminal in which a connection portion can be easily shaped, and deformation of the connection portion is prevented so as to ensure an electrical connection of the connection portion to a female terminal. The connection portion is formed at a front end of the male terminal, and is adapted to be electrically connected to a female terminal. The connection portion includes a bottom base portion and a contact portion, and the connection portion is bent and folded, with the contact portion superposed on the bottom base portion. A curved recess (reinforcement portion) is formed by bending at a generally central portion of the contact portion, and the reinforcement portion projects into an internal space of the connection portion, and is held in contact with the bottom base portion. By thus forming the curved reinforcement portion at the contact portion, and by holding the reinforcement portion in contact with the bottom base portion, the strength of the contact portion is increased. Therefore, when an external force acts on the contact portion or the bottom base portion, the contact portion and the bottom base portion are positively prevented from being deformed or crushed into the space.
