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 of a flexible circuit flat cable, said detachment and displacement protection structure comprises:

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

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

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 an 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

the retention slot of the plastic member of the inserter engages the recess of the flexible circuit flat cable;

wherein the flexible circuit flat cable has a first surface and a second surface, the flexible circuit flat cable extends in a flat cable extension direction to form a free end having an insertion section and the inserter positioning section in an area adjacent to the insertion section;

wherein a plurality of conductive traces are formed on a flexible substrate, the conductive traces extend through the inserter positioning section to reach the insertion section of the flexible circuit flat cable and form a plurality of the conductive terminals in the insertion section;

wherein an insulation cover layer is formed on the conductive traces as the first surface; and

wherein the inserter is positioned on the inserter positioning section, the inserter has a metal member and the 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.

2. A detachment and displacement protection structure of a flexible circuit flat cable, said detachment and displacement protection structure comprises:

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

a retention section formed on a plastic member of an 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 a 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;

wherein the flexible circuit flat cable has a first surface and a second surface, the flexible circuit flat cable extends in a flat cable extension direction to form a free end having an insertion section and the inserter positioning section in an area adjacent to the insertion section;

wherein a plurality of conductive traces are formed on a flexible substrate, the conductive traces extend through the inserter positioning section to reach the insertion section of the flexible circuit flat cable and form a plurality of the conductive terminals in the insertion section;

wherein an insulation cover layer is formed on the conductive traces as the first surface; and

wherein the inserter is positioned on the inserter positioning section, the inserter has the metal member and the 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.
