Abstract
In a connection structure of a flat cable to terminals of the present invention, the conductors held by the back film of the flat cable are ultrasonic welded to the terminals of an external part. In this arrangement, even if the conductors are formed to a very thin thickness, since they are neither twisted nor separated from each other, solid-state welding can be made to target positions.
Claims4
A connection structure, comprising:
- a back film;
- a plurality of conductors supported by said back film;
- a plurality of terminals, each of said terminals having an ultrasonic weld that welds each of said terminals with one of said plurality of conductors at a position where said conductors are only supported by said back film;
- and
- an external part securing said plurality of terminals, said external part being fastened to said back film by a plurality of extensions passing through said back film;
- wherein said plurality of conductors and said plurality of terminals each has a predetermined thickness and each is separated by a plurality of longitudinally extending spaces such that the welding of said plurality of terminals with said plurality of conductors align the longitudinally extending spaces of said conductors and said terminals and partially melt said back film into a plurality of projections disposed within said aligned plurality of longitudinally extending spaces, said projections extending above a welded thickness of said conductors.

A connection structure, comprising:
- a back film having a plurality of positioning holes and a plurality of outside edges, each outside edge having a partially enclosed aperture disposed at an equal distance from an end of said back film;
- a plurality of conductors supported by said back film forming a flat cable, said plurality of conductors disposed on said back film such that each partially enclosed aperture exposes at least an edge of one of said plurality of conductors;
- and
- a plurality of terminals, each of said terminals having an ultrasonic weld that welds each of said terminals with one of said plurality of conductors at a position where said conductors are supported only by said back film.
