Abstract

For easy removal of a flat-plate-shaped signal transmission medium while reduction in height and size is achieved with a simple structure, a structure is adopted for an electric connector as follows. That is, a release operating part of a lock releasing member which causes a lock member in an engaged state to make a transition to a released state is arranged along an insertion opening. The release operating part and a release acting part are arranged in opposite regions in a radius direction of rotation of a support shaft part. The release operating part can make reciprocating rotations between an initial position away from the insertion opening and an acting position close to the insertion opening. Thus, when a flat-plate-shaped signal transmission medium is removed, the flat-plate-shaped signal transmission medium can be held while the engaged state of the lock member with respect to the flat-plate-shaped signal transmission medium is released by one hand of an operator.

First claim

What is claimed is:

1. An electric connector to be mounted on a circuit wiring board for use, comprising:
an insulating housing inside which a terminal portion of a flat-plate-shaped signal transmission medium is inserted through an insertion opening provided as extending in a narrow elongated shape;
a lock member which retains the flat-plate-shaped signal transmission medium by an engaging part becoming in an engaged state with respect to the flat-plate-shaped signal transmission medium inserted inside the housing;
a conductive contact member to be attached to the housing and electrically connected to the flat-plate-shaped signal transmission medium retained by the lock member; and
a lock releasing member having a release operating part attached to the housing as being in a state of making reciprocating rotations about a support shaft part extending along an extending direction of the insertion opening and a release acting part which operates in an interlocked manner with the rotation of the release operating part,
with the release operating part of the lock releasing member rotated from an initial position to an acting position, the release acting part making contact with the lock member and the engaging part of the lock member in the engaged state making a transition to a released state, wherein
the release operating part provided to the lock release member is arranged as extending along the extending direction of the insertion opening,
the release operating part and the release acting part of the lock releasing member are arranged so as to be opposed to each other across the support shaft part in a radius direction of rotation about the support shaft part, and
the release operating part of the lock releasing member is positioned away from the insertion opening at the initial position and is positioned close to the insertion opening at the acting position.

2. The electric connector according to claim 1 , wherein
the lock member is arranged on each of both side portions of the insertion opening to form a pair in the extending direction of the insertion opening.

3. The electric connector according to claim 1 , wherein
the lock releasing member is provided with a positioning part which makes contact with the housing when the release operating part is rotated to the acting position.

4. The electric connector according to claim 1 , wherein
when the release operating part of the lock releasing member is rotated from the initial position to the acting position, the release acting part is positioned away from the insertion opening.
