Ultra-small connector for connecting a flexible printed circuit
A connector has a base having an opening formed at a front surface, to which a distal end of a flexible printed circuit is inserted, and insertion holes passing from the front surface to a rear surface arranged in a line, a connection terminal inserted into the insertion hole of the base, a support fitting arranged on both side edges of the base in which an elastic temporary holding portion is extended from one end to a first side and a lock long tongue piece is extended to a second side opposite the first side, and an operation lever for supporting a turning shaft portion arranged in a projecting manner from both side end faces on the same axis center at the base so as to be turnable, and including a lock cutout portion so as to communicate to a slit formed along an edge of the side end faces.
1. A connector comprising:
a base comprising:
an opening formed at a front surface of the base, to which a distal end of a flexible printed circuit is inserted, and
a plurality of insertion holes passing from the front surface to a rear surface arranged in a line;
a connection terminal inserted into the insertion hole of the base;
a support fitting arranged on both side edges of the base in which an elastic temporary holding portion is extended from one end to a first side and a lock long tongue piece is extended to a second side opposite the first side; and
an operation lever for supporting a turning shaft portion arranged in a projecting manner from both side end faces on the same axis center at the base so as to be turnable, and including a lock cutout portion so as to communicate to a slit formed along an edge of the side end faces;
wherein the lock long tongue piece extending from the elastic temporary holding portion is fitted into the slit of the operation lever in a case where the operation lever is turned when the flexible printed circuit is inserted from the opening of the base, and a temporary holding cutout portion of the flexible printed circuit is engaged and positioned at the elastic temporary holding portion of the support fitting, and
wherein when the operation lever is turned in a case where the distal end of the flexible printed circuit inserted into the opening of the base is brought into contact with the elastic temporary holding portion of the support fitting and the support fitting is elastically deformed, the lock long tongue piece engages the lock cutout portion of the operation lever and inhibits the turning operation of the operation lever.
2. The connector according to claim 1 , wherein a lock step portion, to which the lock long tongue piece is fitted, is formed between the slit of the operation lever and the lock cutout portion.
3. A connector comprising:
a base comprising:
an opening formed at a front surface of the base, to which a distal end of a flexible printed circuit is inserted, and
a plurality of insertion holes passing from the front surface to a rear surface arranged in a line;
a connection terminal inserted into the insertion hole of the base;
a support fitting arranged on both side edges of the base in which an elastic temporary holding portion is extended from one end to a first side and a lock long tongue piece is extended to a second side opposite the first side; and
an operation lever for supporting a turning shaft portion arranged in a projecting manner from both side end faces on the same axis center at the base so as to be turnable, and including a lock cutout portion so as to communicate to a slit formed along an edge of the side end faces;
wherein the lock long tongue piece extending from the elastic temporary holding portion is fitted into the slit of the operation lever in a case where the operation lever is turned when the flexible printed circuit is inserted from the opening of the base, and a temporary holding cutout portion of the flexible printed circuit is engaged and positioned at the elastic temporary holding portion of the support fitting, and
wherein when the flexible printed circuit is pulled with the operation lever being turned, the lock long tongue piece extended to an opposite side of the elastic temporary holding portion is positioned in the slit of the operation lever and elastic deformation of the support fitting is regulated even when the temporary holding cutout portion arranged at the distal end of the flexible printed circuit is brought into contact with the elastic temporary holding portion of the support fitting.
