Abstract:
An insulation displacement connector (IDC) assembly for terminating a flat flexible cable, comprising:a first connector comprising a first dielectric housing receiving a plurality of first terminals therein and forming a pair of latching portions on opposite ends thereof; anda second connector comprising a second dielectric housing, a plurality of second terminals received in the second dielectric housing, a terminating cover mounted to the second housing for facilitating termination between the flat flexible cable and the second terminals, and a pressing member attached to the terminating cover for securely positioning the flat flexible cable between the terminating cover and the pressing member, the pressing member comprising a main body and a latching arm downwardly extending from each end of the main body for engaging with corresponding latching portions of the first housing, a curved connecting portion being formed between the main body and each latching arm for providing the latching arm with proper resiliency relative to the main body and for allowing the latching arm to pivot thereabout, each latching arm comprising a pressing section at one end thereof for facilitating manual operation thereof, and a latching hook at the other end thereof for latching with corresponding latching portion of the first housing;wherein each curved connecting portion of the pressing member resiliently deforms for ensuring corresponding latching arm to be smoothly driven to outwardly pivot about the curved connecting portion thereby releasing the second connector from the first connector when an external force is exerted on the pressing section of the latching arm;wherein each curved portion of the pressing member comprises a curved body connecting the main body with the corresponding latching arm, a groove being defined in the curved body between the main body and the latching arm for providing the curved connecting portion with sufficient deformation space and proper resiliency for providing the latching arm with sufficient pivotal clearance;wherein a pair of bumps respectively extends from inner surfaces of the latching arm and the main body into the groove for limiting a pivotal movement of the latching arms about the curved connecting portion;wherein each latching portion of the second housing forms a pair of hooks for engaging with corresponding latching hooks of the pressing member;wherein a pair of engaging portions perpendicularly extends from opposite ends of the main body of the pressing member for engaging with the terminating cover;wherein each engaging portion of the pressing member further comprises a protrusion at a free end for engaging with the terminating cover;wherein the second housing comprises an upper portion defining a plurality of receiving passageways for receiving the second terminals therein, and a lower portion forming a cavity for engaging with the first housing;wherein the first housing comprises a projecting portion for receiving the first terminals therein and for being received within the cavity of the second housing;wherein a pair of yokes is integrally formed with the upper portion of the second housing;wherein a pair of receiving channels is defined in opposite ends of the second housing proximate corresponding yokes for engaging with the terminating cover;wherein a pair of cantilevered arms perpendicularly extends from opposite ends of the terminating cover for being inserted into corresponding receiving channels of the second housing, and each cantilevered arm forms a latching hook on a free end thereof for engagingly abutting against an inner surface of the corresponding yoke;wherein a pair of receiving slots is defined in opposite ends of the terminating cover for engaging with the pressing member;wherein a pair of rod-like engaging portions perpendicularly extends from opposite ends of the pressing member proximate the curved connecting portion for being engagingly inserted into corresponding receiving slots of the terminating cover;wherein the terminating cover comprises a main plate defining a plurality of arcuate recesses in a bottom surface thereof for engaging with corresponding wires of the flat flexible cable.
