[0050] The flat cable main body 2 mainly includes: a plurality of wirings 5 ​​arranged in stripes; and an adhesive layer 7 that surrounds the plurality of wirings 5 ​​(specifically, a The way of the surrounding surface) is arranged on the insulating layer on the front and back sides. In addition, in the flat cable main body 2 , a pair of insulating films 6 a and 6 b cover the front and back surfaces of the plurality of wirings 5 ​​via the adhesive layer 7 . In addition, "front and back" is defined as one surface side as the front surface and the other surface side as the reverse surface for convenience, and does not specifically limit the structure of the flexible fl...

[0155] Figure 9 The connecting piece 51 replaces the Figure 5 The connecting sheet 21 is used for electrical connection of a flexible flat cable having a plurality of wires. Figure 9 The connecting sheet 51 has the conductive paste part 8 , the adhesive part 59 , the adhesive part 60 and the release film 22 . for Figure 9 The connection sheet 51 has a release film 22 laminated on one surface of the conductive paste portion 8 , the adhesive portion 59 , and the adhesive portion 60 . The conductive paste part 8, the adhesive part 59, and the adhesive part 60 are arranged in the same layer. Figure 9 The conductive paste part 8 in the connecting piece 51 and the release film 22 are connected with Figure 5 Since the conductive paste portion 8 and the release film 22 of the connection sheet 21 are the same, the same reference numerals are assigned and descriptions thereof are omitted.

Abstract

The objective of the present invention is to provide a connection sheet that allows conductivity to be increased between wires to be connected while promoting a reduction in the thickness of the connecting portion, and space saving. This connection sheet is to be used for electrically connecting flexible flat cables, each having a plurality of wires. This connection sheet comprises: a plurality of electrically conductive paste portions which are band-shaped and disposed in parallel so as to correspond to the plurality of wires in a planar view, and contain electrically conductive particles and binders; and an adhesive portion disposed at least in between the plurality of electrically conductive paste portions, and having thermoplastic resin as the main component. The adhesive portion may be disposed in such a manner as to surround the plurality of electrically conductive paste portions in a planar view. The average thickness of the electrically conductive paste portions may be the same as the average thickness of the adhesive portion. The average width of the electrically conductive paste portions may be smaller than the average width of the wires. This connection sheet may further provided with a pressure-sensitive adhesive portion disposed in the same layer as the electrically conductive paste portions and the adhesive portion.

Description

technical field [0001] The present invention relates to a connection piece, a flexible flat cable, a connection structure of the flexible flat cable, and a connection method of the flexible flat cable. Background technique [0002] Flexible flat cables are used for electrical connection of electronic components housed in electronic devices. This flexible flat cable has a structure in which a plurality of flat ribbon-shaped conductors are covered with an insulating layer. The flexible flat cable is connected to a dedicated connector through a normal end, and is electrically connected to other conductors via the dedicated connector. [0003] However, if such a dedicated connector is used, the connection portion becomes large, which violates demands for thinning and space saving of electronic components. [0004] Therefore, currently, a connection structure that can promote thinning, space saving, and the like of electronic components without using a dedicated connector has a...
