A coaxial connector includes a housing and a retainer attached to the housing. The housing includes a terminal receiving portion into which a terminal is insertable from behind. The terminal includes a crimp portion crimped to have a polygonal cross-sectional shape, and a flange portion located forward of the crimp portion when the terminal has been inserted in the terminal receiving portion, the flange portion protruding circumferentially outward beyond the crimp portion. The retainer includes a fitting portion fitted around the crimp portion of the terminal including at least one corner of the crimp portion in an attached state in which the terminal has been received in the terminal receiving portion in a normal position and the retainer has been attached in an engagement position, and an abutment portion in abutment with the flange portion of the terminal from behind in the attached state.

Coaxial connector

Provided is a male connector capable of easily engaging with a female connector. A male connectorincludes a hood portionwith a cylindrical shape that is fit into, from a projecting endA side, an engagement cylindrical portionformed as an opening of a female connector, wherein the hood portionis provided with the at least one guide projection portionprojecting forward beyond the projecting endA with an annular shape.

Male connector and connector assembly

A connector is provided with a housing, a grommetarranged to cover an outer periphery of the housing, and a grommet coverarranged to cover an outer periphery of the grommet. The grommet coverincludes a tip portionon one end on an opening side. The housingincludes a restricting portionE. The restricting portionE includes a recessE inside which the tip portionof the grommet coveris to be arranged. The recessE of the restricting portionE includes a restricting bodyarranged to face an outer side of the tip portionof the grommet cover

Connector

A female connector housing () is provided with a lever accommodating portion (B), and a lever () is rotatably mounted on an outer surface () of a main body portion (A) inside. The lever () is provided with a lock arm (). An operating portion (B) is provided on a tip part of the lock arm () and covered by a protecting portion (). In the case of separating male and female connectors (M, F), the locking of a lock protrusion () and a locking projecting edge () is released by pinching a first pinching surface () formed on the operating portion (B) of the lock arm () and a second pinching surface () of the protecting portion (). Since the first pinching surface () and the second pinching surface () are arranged along a deflecting direction of the lock arm (), a pinching operation is facilitated.

Lever-type connector

A connector includes: (i) a lock arm that extends rearwardly in a cantilevered shape from a housing main body, and (ii) a detecting member arranged to be movable forward from an initial position to a detecting position. The detecting member includes (i) an elastic arm portion extending in a cantilever shape diagonally upward and forward; (ii) an abutting portion at an extended end portion of the elastic arm portion and restricting movement of the detecting member from the initial position to the detecting position; (iii) a pair of walls, one at the left and one at the right, raised from the top surface of the housing main body; (iv) a bridge portion connecting top ends of the walls; and (v) an excessive bending restriction portion restricting excessive bending of the lock arm upward by covering the top surface of the lock arm with the bridge portion.

Connector with detecting member

A detector () movable from an initial position to a detection position is mounted on a housing main body (). The detector () includes a resilient arm () resiliently deformable in a height direction. The resilient arm () contacts a lock arm () from behind before the housing main body () is connected to a mating housing () to prevent a forward movement at an initial position. When the housing main body () is properly connected to the mating housing (), the detector () reaches a detection position where the resilient arm () enters a deformation space () by being pushed forward from the initial position. At the initial position, the resilient arm () applies a pre-load to the lock arm () in the height direction.

Connector and connector assembly

A protection wall () stands up from a rear end part of a housing main body () and restricts an operation of a disengaging portion () of a lock arm () by covering the disengaging portion (). A detector () is made movable to a detection position by being pushed forward when the housing main body () is properly connected to a mating housing (). Further, the detector () includes a rear portion () located behind the lock arm () and to be pushed when the detector () is moved to the detection position. A disengagement window () used to operate the disengaging portion () is formed on a position of the rear portion () behind the disengaging portion ().

A lock arm () is cantilevered back from a front end part of a housing main body (). The lock arm () includes an accommodating recess () that is open toward a deformation space () therefor and toward the back. When the housing main body () is connected properly to a mating housing () and a detector () is pushed from a standby position to a detection position, a part of the detector () is inserted into the accommodating recess ().
