Abstract

Disclosed is a detachment and displacement protection structure for insertion of flexible circuit flat cable. An inserter positioning section is formed on a flexible circuit flat cable and coupled with an inserter, which includes a metal member and a plastic member. In assembling, the plastic member is first positioned on a first surface of the inserter positioning section of the flexible circuit flat cable, and then the metal member is fit over the plastic member. A detachment and displacement protection structure is provided on the inserter positioning section to constrain the inserter from displacing and detaching in a flat cable extension direction due to being acted upon by an external force when the inserter is positioned on the inserter positioning section.

Claims

1. A detachment and displacement protection structure for insertion of flexible circuit flat cable, the flexible circuit flat cable having a first surface and a second surface, the flexible circuit flat cable extending in a flat cable extension direction to form a free end that defines an insertion section and forming an inserter positioning section in an area adjacent to the insertion section;

the first surface of the flexible circuit flat cable forming a plurality of conductive traces, the conductive traces extending through the inserter positioning section to reach the insertion section of the flexible circuit flat cable and forming a plurality of the conductive terminals in the insertion section;

an insulation cover layer formed on the first surface of the flexible circuit flat cable and the conductive traces;

an inserter positioned on the inserter positioning section, the inserter having a metal member and a plastic member, so that in assembling, the plastic member is first positioned on the first surface of the inserter positioning section of the flexible circuit flat cable and then the metal member is fit over the plastic member;

characterized in that;

the flexible circuit flat cable comprises a detachment and displacement protection structure in the inserter positioning section so as to constrain the inserter from displacing and detaching in the flat cable extension direction due to being acted upon by an external force when the inserter is positioned on the inserter positioning section.

2. The detachment and displacement protection structure for insertion of flexible circuit flat cable as claimed in claim 1, wherein the detachment and displacement protection structure comprises:

at least one projecting lug section formed on a side edge of the flexible circuit flat cable; and

a retention section formed on the plastic member of the inserter at a location corresponding to the projecting lug section of the flexible circuit flat cable;

whereby when the plastic member is mounted to the inserter positioning section of the flexible circuit flat cable, the retention section of the plastic member of the inserter engages the projecting lug section of the flexible circuit flat cable.

3. The detachment and displacement protection structure for insertion of flexible circuit flat cable as claimed in claim 2, wherein the detachment and displacement protection structure comprises:

at least one recess formed in a side edge of the flexible circuit flat cable; and

a retention slot formed in the plastic member of the inserter at a location corresponding to the recess of the flexible circuit flat cable;

whereby when the plastic member is mounted to the inserter positioning section of the flexible circuit flat cable, the retention slot of the plastic member of the inserter engages the recess of the flexible circuit flat cable.

4. The detachment and displacement protection structure for insertion of flexible circuit flat cable as claimed in claim 1, wherein the detachment and displacement protection structure comprises:

at least one projecting lug section projecting from a side edge of the flexible circuit flat cable within the inserter positioning section;

at least one projecting wing section projecting from a side edge of the flexible circuit flat cable, the projecting wing section being arranged adjacent to the projecting lug section with a predetermined distance formed therebetween; and

a retention section formed on the plastic member of the inserter at a location corresponding to the projecting lug section of the flexible circuit flat cable;

whereby when the plastic member is mounted to the inserter positioning section of the flexible circuit flat cable, the retention section of the plastic member of the inserter engages the projecting lug section of the flexible circuit flat cable and when the metal member is fit over and coupled to the plastic member, a rear edge surface of the metal member is in engagement with the projecting wing sections.

5. The detachment and displacement protection structure for insertion of flexible circuit flat cable as claimed in claim 1, wherein the detachment and displacement protection structure comprises:

at least one locking section formed on the plastic member; and

at least one counterpart locking section formed on the metal member and corresponding to the locking section of the plastic member;

wherein when the metal member is fit over and encloses the plastic member, the counterpart locking section of the metal member engages the locking section of the plastic member.

6. The detachment and displacement protection structure for insertion of flexible circuit flat cable as claimed in claim 1, wherein the detachment and displacement protection structure comprises:

at least one stop section, which is formed on the first surface of the flexible circuit flat cable, whereby when the metal member of the inserter is fit over and coupled to the plastic member, a rear end surface of the metal member is in engagement with the stop section to constrain displacement of the metal member.
