A waterproof connector includes a pair of mating connector housings having connecting terminal fittings therein. A covering body rotatably is attached to a cylindrical peripheral wall of one of the connector housings. The covering body has a stopper hook projecting from its inner wall and is mounted with a resilient member for exerting a reaction force to the other connector housing. A locking hook projects from an outer peripheral wall of the other connector housing and engages with the stopper hook of the covering body. An outer wall of the other housing is inserted into the covering body and the stopper hook engages with the locking hook so that the pair of connector housings completely engage and lock to each other.

A female terminal in which excessive flexing of a resilient contact piece portion is prevented by simple working. The female terminal of the invention includes deformation prevention folded portions which are bent respectively at opposite side portions of a second folded piece portion toward a first folded piece portion. The deformation prevention folded portion supports the first folded piece portion in a maximumly-flexed position of the first folded piece portion. When a male terminal, having a proper thickness, is inserted into the female terminal, a predetermined gap is formed between the first folded piece portion and the deformation prevention folded portion. Even when the first folded piece portion is flexed upon insertion of a thick foreign object into a hollow contact portion or upon prizing of the first folded piece portion in the hollow contact portion, the deformation prevention folded portion supports the first folded piece portion in the maximumly-flexed position thereof, and therefore a resilient contact piece portion will not be permanently deformed. And besides, the deformation prevention folded portion can be formed by simple working.

Female terminal

A partial-fitting prevention connector which can be positively fitted relative to a mating connector, and is prevented from being only partially fitted relative to the mating connector. When the partial-fitting prevention connector (1) is fitted relative to a mating connector (2), a retaining member (25), formed on a lock member (22), abuts against a retaining projection (34) formed on the mating connector (2), and the lock member (22) is pushed against the bias of a spring (23) in a rearward direction away from the mating connector. After the lock member has moved a predetermined distance, lock release projections (26a and 26b), formed on the lock member (22), slide over lock release projections (42a and 42b) formed on a support structure (41), thereby pivotally moving the lock member (22). When the fitting operation is further continued, the lock member (22) is urged by the spring (23) in the forward direction toward the mating connector and engages the retaining projection (34) to thereby retain the connectors to each other.

A pair of connector elements, one connector element having a locking arm, the other connector element having a hood for receiving the one connector element and a locking protrusion provided within the hood are locked in engagement by the locking arm and the locking protrusion when they are completely coupled with each other. When the connector elements are not used or before they are coupled with each other, a body for preventing the one connector element from being fit into the other connector element is inserted in the hood of the other connector element. The body has a locking arm to be engaged with the locking protrusion and a locking portion into which a dedicated jig for pulling out the body from the hood is to be inserted. Thus, in electric wiring (e.g., an air bag for motor vehicles), a connection of the connector elements is prevented with a false current is flowing through one of the connector elements, thus preventing error (e.g., an explosion in an inflator).

The body has a locking arm to be engaged with the locking protrusion and a locking portion into which a dedicated jig for pulling out the body from the hood is to be inserted. Thus, in electrical wiring for e.g. an air bag for motor vehicles, it is prevented that when the pair of connector elements are to be coupled with each other, they are connected with a false current flowing through the one connector element and explosion happens in an inflator.

Electric connector with false connection preventing mechanism and method

A screw tightening type connector having a female connector and a male connector fitted in the female connector. The female connector is provided with a female screw body, while a male screw body is provided on the male connector. The male connector is screwed into the female screw body and is tightened whereby the female connector and the male connector are fitted in each other. A rotational-force imparting section is provided for imparting a rotational force to the male screw body. The rotational-force imparting section has a rotary shaft extending in a direction intersected with a fitting direction of the male connector into the female connector. A rotational-force transmitting section is provided for converting the rotational force from the rotational-force imparting section to a rotational force in a direction intersected with the rotary shaft to transmit the rotational force to the male screw body.

Electrical connector housing

One of the mating connector housings has a locking arm and the other connector housing has an engagement sleeve that receives the locking arm. The locking arm rises through a base at the front outer circumference of the first housing and extends axially rearwardly. The locking arm has guide means formed at the base. The engagement sleeve has engagement groove means formed in side walls thereof that extend axially from the front opening toward the rear and which receives the guide means. When the paired connector housings are connected together, the guide means of the locking arm are received into the engagement groove means in the engagement sleeve to prevent the weak portion of the connector housing formed with the locking arm from being deformed, thus providing a good locking feel and also an adequate engagement stroke. This makes the complete connection of the connector housings easily verifiable.

Housing for an electrical connector

An electric connector with a terminal conductor detaining mechanism for restraining terminal conductors from slipping out of the electric connector. The electric connector comprises: a connector shell having a plurality of terminal chambers and provided with a pair of flexible, temporary locking strips and with a pair of main locking parts; and a terminal conductor detaining member provided with a plurality of terminal conductor detaining fingers and a pair of flexible locking arms. The terminal conductor detaining member is combined temporarily with the connector shell with the fexible locking arms thereof engaging the flexible locking strips of the connector shell, respectively, to keep the connector shell and the terminal conductor detaining member in a temporarily combined state. The terminal conductor detaining member is combined completely with the connector shell by pressing the terminal conductor detaining member into the connector shell so that the locking arms engage the main locking parts of the connector shell, respectively. In pressing the terminal conductor detaining member into the connector shell to combine the terminal conductor detaining member and the connector shell in a completely combined state, the flexible locking strips must be pressed forcibly to allow the terminal conductor detaining member to move further into the connector shell. Thus, the accidental complete combination of the terminal conductor detaining member and the connector shell is prevented.
