A connector includes an outer tube, an inner tube formed to be continuous from the outer tube, and a partition wall configured to isolate the outer tube and the inner tube. The partition wall has an elongate convex portion, the convex portion is formed on a surface of the partition wall in a side of the outer tube, and the convex portion has a through hole penetrating the partition wall which is formed in the convex portion and a terminal is press-fitted into the through hole.

Connector

A connector is fitted into a mating connector including a receiving member, and includes a locking arm for locking the receiving member. The locking arm includes an arm member which extends in a fitting direction to the mating connector, and a locking member which is provided at a tip end of the arm member or in the neighborhood thereof so as to project in a direction intersecting the direction of fitting, and locks the receiving member. The locking member includes a claw which is formed at a tip end of the locking member so as to project in a direction opposite to the fitting direction to the mating connector and is caught by the receiving member.

Connector with a claw of locking member

A first shielding case of a receptacle respectively has arms extending to a forward side to be forwardly folded back from proximal ends fixed to a back end of an upper surface wall, stopper walls formed on free ends of the arms and projecting from outside to inside of the first shielding case and abut on an unauthorized plug in inserting the unauthorized plug, plug pickup parts formed on the free ends of the arms and are integrally formed in parallel with the stopper walls and projecting from outside to inside of the first shielding case and abut on an authorized plug in of inserting the authorized plug, and holes formed near to an opening of the upper surface wall, the holes into which the stopper walls and the plug pickup parts are inserted, on both ends of a width direction.

Wrong insertion preventive structure of connector

A connector includes a connector terminal electrically connected with a terminal (a counterpart terminal) of a counterpart component and a connector housing holding therein the connector terminal. The connector terminal includes a cylindrical terminal insertion section into which the counterpart terminal is to be inserted, a spring section which is brought into contact with the counterpart terminal in a cylinder of the terminal insertion section, and a displacement restriction section restricting excessive displacement of the spring section in the cylinder of the terminal insertion section when the spring section is brought into contact with the counterpart terminal, and the displacement restriction section includes a stabilizer which extends outward from the terminal insertion section while being supported continuously to a restriction part for the spring section.

Connector terminal having a cylindrical terminal insertion section

A connection terminal includes a terminal fitting part that fits with a leading end portion of a mating connection terminal, a square tubular part that continues to a rear end of the terminal fitting part and a lance engagement surface that is formed on the square tubular part and that, when the connection terminal is inserted into a terminal accommodation hole of a connector housing, is contacted to a projected part of a lance provided in the terminal accommodation hole to prevent the connection terminal from disengaging from the terminal accommodation hole. The lance engagement surface is a hook-shaped engagement surface that is formed by an opening across a top wall of the square tubular part facing the lance and a sidewall part continuing to a side edge of the top wall.

Connection terminal

A connector includes a housing and terminal fittings attached to a printed circuit board. The terminal fittings form two terminal rows. In the terminal rows, one end parts of the terminal fittings are piled in a fitting plate part of the housing to which a mate side connector is fitted in a mutually parallel state and arranged in parallel with a surface of the printed circuit board. Central parts of the terminal fittings are bent. The other end parts are connected to a conductor pattern of the printed circuit board. In the other end parts of the terminal fittings, outward bent parts are provided which are bent outward in the direction of width of the housing. Tip ends of the other end parts of all the terminal fittings are arranged with spaces left between them along the direction of width of the housing.
