A connector with a lock mechanism is provided. The lock mechanismcomprises a lock armprovided on an outer surface of a plug frameA and a pair of supportsA,B arranged near respective lateral ends of the lock armThe pair of supportsA,B are formed integrally to protrude from the outer surface of the plug frameA. A pair of torque rodsA,B being fixed to the pair of supportsA,B support the lock armon respective lateral ends such that a hookA to be latched on a receptaclemay swing around the rodsA,B. A forward portionF including the hookA is formed with a concaved portion Aof a forward slide moldF. A latch faceof the hookA is formed with a projecting portion Bof a backward slide moldR.

Lock structure and connector with lock mechanism of lock structure

A connector with a lock mechanism, in which maximum stress generated at a hinge joint as a fulcrum portion of a lock arm is reduced. A lock armis provided on an outer wall of a plug housing. A plugcomprises a lock mechanism, in which the lock armis latched on a latchprovided on a receptaclefor maintaining a state of coupling to the receptacle. The lock armcomprises a hookA projecting in a direction of insertion of the receptacle, a point of pressureB (a finger depressing portion) positioned on an opposite side to the hookA, and a fulcrum portionC. The fulcrum portionC has a pair of torque rodsA,B supporting the lock armat lateral ends so as to allow the hookA to swing.

Connector with lock mechanism

Electrical connector

A housing made of an insulating synthetic resin has a connecting recess opened in the connecting direction. The side walls defining the connecting recess is provided with terminal retainer recesses arranged side by side in the lateral direction. The openings are formed in the portion of the outer side surface of each side wall which correspond to the partition walls separating adjacent terminal retainer recesses from each other. The openings have the terminal retainer holes, which are formed on both sides of the corresponding partition walls, opened to the exterior thereof. When the housing is molded, the pins for forming the openings are interposed among the ribs of the metal mold which are used to form the adjacent terminal retainer recesses, the deformation of the ribs being thereby held down.

Electrical connector for boards and method of making

Housing for electrical connector

An electric connector comprises a base connector fitted to a surface of a circuit board and a socket connector connected to ends of wires. The base connector includes a base housing having a mounting surface and two rows of base contacts. The socket connector includes a socket housing to be fitted to the base housing in a predetermined fitting direction perpendicular to the mounting surface, and two rows of socket contacts. Each of the base contacts has a fork-like shape including semi-fixed piece portion and a resilient piece portion. The resilient piece portion of each base contact is restrained from displacing by an intermediate wall of the base housing. The semi-fixed piece portion of each base contact is received by a side wall of the base housing.

Electric connector

An electric connector, comprising a base connector () fixed onto a mounting surface () and a socket connector () extracted from the inserting space () of the base connector () along the extracting direction (X) generally orthogonal to the mounting surface (), wherein, when an electric conductor () extending in the direction parallel with the mounting surface ()(Y) is pulled in the direction parallel with the mounting surface ()(Y), a tension is converted into a force in the direction of extracting the socket connector () (X) by the activation of the cam surface () of the base connector () and the cam surface () of the socket connector (), whereby the socket connector () can be removed smoothly.
