Cable connector
A cable connector includes: a contact ( 45 A, 45 B) supported by an insulator ( 20 ) having a cable insertion groove ( 21 ); a lock member ( 65 ) rotatable about a rotation shaft ( 74 ), between a lock position where a lock portion ( 68 ) of the lock member faces a locked portion ( 98 ) of a sheet-like cable ( 93 ) inserted in the insulator and an unlock position where the lock portion does not face the locked portion; and a bias portion ( 80 ) for biasing the lock member to the lock position, wherein an inner surface of the cable insertion groove includes a reference surface ( 21 a ) which is an end surface in a movement direction of the lock portion from the lock position to the unlock position, and a rotation center G of the rotation shaft is located on a side opposite to the movement direction, with respect to the reference surface.
1. A cable connector comprising:
an insulator having a cable insertion groove into which a sheet-like cable having a locked portion is removably insertable;
a contact supported by the insulator and coming into contact with the cable inserted in the insulator;
a lock member rotatable about a rotation shaft thereof supported by the insulator, between a lock position where a lock portion of the lock member faces the locked portion inserted in the insulator from an escape direction of the cable from the insulator and an unlock position where the lock portion does not face the locked portion from the escape direction, the lock member further having a spring receiving projection projected from an outer surface of the lock member on the unlock position side; and
a bias portion for biasing the lock member to the lock position, and allowing the lock member to rotate to the unlock position by elastic deformation,
wherein an inner surface of the cable insertion groove includes a reference surface which is an end surface in a movement direction of the lock portion from the lock position to the unlock position,
a rotation center of the rotation shaft is located on a side opposite to the movement direction, with respect to the reference surface, and
the bias portion abuts on the spring receiving projection from the unlock position side and biases the lock member to the lock position.
2. The cable connector according to claim 1 ,
wherein the rotation center of the rotation shaft is located on the side opposite to the movement direction of the lock portion from the lock position to the unlock position, with respect to a contact portion of the lock portion located at the lock position with the locked portion.
3. The cable connector according to claim 1 ,
wherein the cable includes a lock portion insertion portion which is a recess or through hole that passes through the cable in a thickness direction and is adjacent to the locked portion, and
the lock portion is a lock claw that, when the lock member is located at the lock position, enters the lock portion insertion portion and faces the locked portion from the escape direction.
4. The cable connector according to claim 1 ,
wherein the contact includes:
a fixed piece attached to the insulator in a fixed state;
an elastic deformation piece coming into contact with the cable inserted in the insulator, and elastically deformable in a thickness direction of the cable; and
a connection portion connecting a base end of the elastic deformation piece and the fixed piece, and enabling the elastic deformation piece to swing in the thickness direction about the base end relative to the fixed piece.
