Wire tubes are fitted to electric wires to which large female terminals are crimped, and are brought into elastically intimate contact with inner walls of large terminal insertion openings of the mat seal. Moreover, each of the wire tubes includes a protruding portion that protrudes rearward from the large terminal insertion opening of the mat seal and is located in the large electric wire insertion opening.

Waterproof connector

A waterproof connector, comprising a pair of male and female housings () engaged with each other. The waterproof connector also comprises a grommet () covering at least one of the housings () and a fastening member () inserted from the grommet () side into the pair of male and female housings () to connect them to each other. In addition, the grommet comprises a sealing part () having a predetermined length along the inserting direction of the fastening member () and formed integrally with a grommet body () at the outlet side end part () thereof.

A through-panel connector, comprising a female connector () and a male connector disposed on one side and the other side of panel () and fitted to each other through a mounting hole () formed in the panel (). The female connector () comprises a plurality of flexible holding ribs (). The holding ribs () are formed on the outer peripheral surface () of the female connector () opposed to the mounting hole inner peripheral surface () of the panel () so as to be extended along the inserting direction of the mounting hole () and separated from the outer peripheral surface () while being extended from the base end part () to the tip part () of the female connector () along the mounting hole inner peripheral surface (). The holding ribs () are biased and held on the mounting hole inner peripheral surface () with the female connector () fitted to the panel ().

Through-panel connector

A lever-fit connector, wherein a rotation prevention lock () preventing a lever () from being rotated when male and female connector housing are fitted (joined) to each other is installed in the inner wall (A) of a lever insert hole () in a female housing (). A rotation lock recessed part () in which the rotation lock part (D) of the rotation prevention lock () is engageably stored is formed in the peripheral surface of the lever (). The angle of the rotation lock part (D) is set so that the rotation lock part (D) is drawn to the lever () side in excessive rotation by bringing the rotation lock part (D) into contact with the side wall surface (B) of the rotation lock recessed part ().

Lever-fitting type connector

A lever type connector is provided with a lever assisting in fitting or detaching first and second connector housings thereof. A lever is fitted to the first connector housing. A plurality of projecting parts is provided in a circumference of the lever. A plurality of receiving parts is provided in the first connector housing to slidably engage with the projecting part. Engagement between the projecting and receiving parts prevents the lever from deformation and warpage in a rotating operation of the lever for the connecting operation. The projecting parts and the receiving parts are configured so that the projecting parts and the receiving parts are engaged only when the lever is positioned so that the fitting force is large in the rotating operation, and the projecting parts and the receiving parts are not engaged when the lever is positioned in another state in which the fitting force is small.

Lever type connector

A lever type connector of the present invention includes a connector housing, a cover, a lever rotatably mounted on the connector housing, and a snap tab mounted on the cover. During rotation of the lever from an unlocking position to a locking position, the snap tab is pressed by the lever and bent, and if the lever reaches the locking position, the snap tab is brought back to lock the lever. The maximum bent inward angle of the snap tab is set to be smaller than the outward inclination angle of the snap tab without being bent. It is possible to prevent contact between the snap tab and the electric wires. The electric wires are prevented from being damaged, and the operation failure of the snap tab is also avoided.

A front wall () is movable between a full locking position and a partial locking position on the front of a female housing (). When the front wall () is at the full locking position, mating tabs () can enter main portions () of the female terminal fittings () through tab insertion holes () of the front wall () for contacting resilient contacts () and an unlocking jig can be inserted into a mold-removal hole () of the female housing () through a jig insertion hole () of the front wall () to disengage a lock (). When the front wall () is at the partial locking position, detection probes () can be inserted into the jig insertion holes () of the front wall () for contacting detecting plates () offset from resilient contacts () in main portions of the female terminal fittings ().

Connector and a method of assembling it

A stabilizer () of a terminal fitting () is divided into a front stabilizer (A) and a rear stabilizer (B) and defining a small clearance therebetween. Thus, the smaller holes (A,B) are formed by the divided stabilizer (), and external matter is less likely to intrude.

An electrical connector includes an insulating housing and a retainer. The housing has a plurality of contact accommodating cavities. The retainer is moveable between a temporary locking position and a main locking position. The retainer has first retainer arms that extend into a front surface of the housing. The first retainer arms have a second locking member formed on a top surface in a vicinity of a free end of the first retainer arms and a third locking member formed on a bottom surface in substantially a center of the first retainer arms. The second and third locking members are configured to abut the housing in the temporary locking position so that the retainer is prevented from moving from the temporary locking position to the main locking position.

An electrical connector reduces backlash of the retainer in a main locking state and increases the rigidity of the front plate of the retainer, while providing dimensional stability, and preventing warpage of the locking arms. The electrical connector comprises a front insertion retainer that is locked to the housing in a temporary locking position and in a main locking position. The retainer comprises a front plate having contact passage holes, and locking arms extending rearward from the upper and lower ends of the front plate. A strip extends in the direction of length and protrudes rearward from the center on the back surface of the front plate, and a recessed groove extends on the front surface of the front plate in a position corresponding to the strip. The housing has a recessed groove that mates with the strip when the retainer is in the main locking position.
