Abstract: To be capable of easily avoiding lengthening and heightening with a simple configuration even in a case where relatively large electric power is supplied. Provided is a configuration in which the conductor resistance of a plurality of contact members 13 and 14 is reduced in accordance with an increment in thickness and energization allowable electric power is increased by one of more of the contact members 13 and 14 being formed thicker than the rest so that an increase in the size of an electric connector such as lengthening and heightening is prevented even in a case where the supply electric power with respect to the electric connector is large and the retention of a flat plate-shaped signal transmission medium F is enhanced by contact portions of the thickness-increased contact members 13 and 14 being pressure-welded to the flat plate-shaped signal transmission medium F.

Abstract: Occurrence of unnecessary conduction or damage upon insertion of a plate-shaped signal transmission medium can be prevented by a simple configuration. The rigidity relation between a medium abutting portion and a coupling beam portion of a contact member is configured so that a contact point portion of the contact member is positioned in the interior of a contact housing portion in a stage before a plate-shaped signal transmission medium is sandwiched when the plate-shaped signal transmission medium is to be inserted to the interior of a medium insertion path along a medium guide surface of an insulating housing. By virtue of this, the contact point portion of the contact member is configured to be maintained in a state in which it is lowered below the medium guide surface upon insertion of the plate-shaped signal transmission medium so that the contact point portion of the contact member does not contact the plate-shaped signal transmission medium.

Abstract: A lock-arm regulating part, which carries out regulation so that a latch lock claw for carrying out specified movement so as to be engaged with or detached from a signal transmission medium inserted in an insulating housing does not carry out non-constant movement different from the specified movement, is provided. The lock-arm regulating part is disposed to be opposed to the lock arm member in two directions including an insertion/removal direction of the signal transmission medium and an insertion/removal orthogonal direction. Since this configuration is employed, when non-constant external force such as pulling force in a direction different from the original insertion/removal direction is applied to the signal transmission medium, part of the lock arm member is configured to abut the lock-arm regulating part and prevent non-constant movement of the latch lock claw.

Abstract: The risks of damage and breakage such as plastic deformation of a lock arm member can be well prevented by a simple configuration.

Abstract: A signal transmission medium inserted into an insulating housing can be held and released in a favorable manner with a simple structure. A pair of lock release parts are arranged to face opposite each other at both outer ends of a signal transmission medium, this pair of lock release parts being integrally and continuously formed to release arms integrally extending from the insulating housing to be movable to approach and separate from each other, with a lock release link mechanism being provided for causing the locking portion to displace in an unlocking direction by moving the pair of lock release parts in directions approaching each other.

Abstract: A signal transmission medium inserted in a connector main body portion, which can be held and released successfully with a simple configuration, is disclosed. A distal end portion of an elastically-displaceable cantilever-shaped locking arm member formed so as to be integral with a board connection leg portion (holddown) is provided with a locking portion engaged with a portion of the signal transmission medium inserted in the connector main body portion to hold the inserted state. The held state of the signal transmission medium is maintained by elastic action of the locking arm member extending in a relatively-elongated shape from a swinging fulcrum. Simultaneously, an unlocking-action force on the locking portion can be reduced, and an unlocking-operation force is stably received by the board connection leg portion (holddown) fixed to a printed circuit board so that improvement in strength is achieved.

Abstract: To allow a signal transmission medium inserted in a connector main body to be held and disengaged excellently with a simple structure, the structure is such that a lock member holding a signal transmission medium inserted in the connector main body is provided to a part of an elastically-displaceable lock arm member extending like a cantilever from a rocking fulcrum and disposed at one end of the connector main body on a rising side to excellently maintain a state of holding the signal transmission medium by the lock member with an elastic action of the lock arm member, a release operation from the lock member is easily performed with a relatively small operation force, and a load transmitted from the lock member to the lock arm member when the signal transmission medium is inserted or withdrawn is received at the end of the connector main body on the rising side to reduce direct load on a circuit wiring board side.
