Abstract:
A partially cut multi-planar flexible printed circuit comprises a substrate, a set of signal conducting elements for differential mode and common mode, a power supply and/or ground. The multi-planar flexible printed circuit is formed by partially grouped cutting a flexible printed circuit at a proper position so that the cross-sectional area of the multi-planar flexible printed circuit at the cut portion can fit in with a small round or square splice hole in addition to a flat rectangular slit for connecting, for example, a liquid crystal display with a notebook computer. Moreover, intervals between edges of a substrate and a plurality of transmission lines are preferably greater than three times of thickness of the substrate.

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).

The circuit substrate has an end that is provided with conductive terminals and an opposite end that is provided with flat cable connection terminals for connection with a flat cable. The circuit substrate has a first surface on which the projection section is formed. A shielding layer covers the projection section and a portion of the first surface. The circuit substrate has a second surface on which a second shielding layer is selectively formed. When the circuit substrate is inserted into an insertion space defined in a connection socket with the conductive terminals thereof, the shielding layer and the projection section of the circuit substrate are put into engagement with and thus retained by the insertion space of the connection socket to thereby fix within the connection socket.
