Abstract:
Provided is a flexible-circuit-board cable having a positioning structure. A connection zone is defined in a free end of the flexible-circuit-board cable and is provided with a plurality of conductive contacts. The connection zone has a first surface on which at least one projection section is formed and a second surface. A shielding layer overlaps the projection section and a portion of the first surface. The second surface of the connection zone is also bonded to a shielding layer. When the connection zone of the flexible-circuit-board cable is inserted into an insertion space defined in a connector, the first and second local zones of the connection zone formed by the shielding layers and the projection section are put into engagement with and thus positioned and retained by walls on opposite sides of the insertion space of the connector to thereby fix within the connector.

A flexible flat cable defines an insertion device mounting section to which an insertion device is mounted. The insertion device includes a metal member that is at least partly formed of a metal material. The flexible flat cable forms thereon conductive traces on which an insulation layer is provided. The insulation layer has a surface, which forms, in at least a portion thereof, a conductive shielding layer.

Abstract:
Disclosed is a flexible printed circuit board with waterproof structure, including a flexible substrate that has a first surface on which a first metal layer is bonded. The first metal layer has an upper surface forming a covered area and at least one mounting zone and the metal layer forms on a surface thereof within the mounting zone a bonding improved waterproof structure. A first insulation layer is formed on the covered area of the upper surface of the first metal layer in such a way not to cover the mounting zone of the first metal so as to expose the mounting zone. A water resistant member is securely mounted to the mounting zone of the first metal layer. The flexible substrate also has a second surface to which a second metal layer and a second insulation layer are mounted. The second metal layer also forms a mounting zone, which is not covered by the second insulation layer so as to expose for mounting the water resistant member. The metal surface inside the mounting zone also forms bonding improved waterproof structure. The waterproof structure improves the bonding strength between the flexible printed circuit board and the water resistant member through proper arrangement and selection of shape, size, and distribution density of holes that are defined in the exposed metal surface. Alternatively, the holes can be made completely through the metal layer in order to also feature control of impedance for high frequency signals.
Abstract:
A cable bundling structure is provided for being set in slidable engagement with a target cable. The cable bundling structure includes a helical wrap member, which wraps around a wrapped section of the target cable. The helical wrap member is selectively composed of one or more sections of wrapping turns and each section is made in a one-piece form having a predetermined wrap width, a predetermined helix angle, and a predetermined wrap diameter and extending a predetermined length in a wrapping direction. The helical wrap member helically wraps around the target cable in such a way that the helical wrap member is in slidable engagement with the target cable and serves as an external protection for the cable. The helical wrap member can be made of an insulation material or an electromagnetic shielding material, whereby besides structural protection of the cable for improving resistance against bending, the external protection formed by the helical wrap member also provides protection against electromagnetic interference (EMI).

A shielded insertion and connection structure for a flat cable connector includes a receiving housing and a hold-down member. The receiving housing forms a receiving compartment and two side walls formed at opposite ends of the receiving compartment. The hold-down member has opposite ends that respectively form pivot structures for pivotal coupling to the side walls and rotation between an open position and a holding position. The hold-down member is made of metal and the receiving housing is at least partly made of metal to form a conduction section, which is connected to a grounding terminal. When the hold-down member is at the open position and a circuit flat cable is inserted into the receiving compartment, the hold-down member is operated to depress and hold the circuit flat cable and the hold-down member is put in electrical connection with the grounding terminal through the conduction section.
