Embodiment 1
[0079] 1. Materials
[0080] (1) Conductive rubber + crosslinking component
[0081] Use a conductive silicone compound commercially available from a silicone rubber material manufacturer. The hardness (JIS type A) of this conductive silicone composite was 73, and the volume resistance was 8Ω·cm. In 100 parts by mass of the conductive silicone composite, 2 parts by mass of a crosslinking agent (SiH functional siloxane) and 0.4 parts by mass of a retarder (siloxane derivative) were homogeneously kneaded. Next, it was rolled with a calender roll, and the rolled sheet of thickness 6.7mm was produced.
[0082] (2) Electrical insulating rubber + curing catalyst
[0083] An electrically insulating silicone compound commercially available from a silicone rubber material manufacturer was used. The electrical insulating silicone compound has a hardness (JIS type A) of 70 and a volume resistance of 10. 14 Ω·cm. 0.4 parts by mass of the platinum catalyst was homogeneously kneaded w...

Abstract
A laminated connector and a manufacturing method thereof, the laminated connector is a laminated type in which a conductive silicone rubber layer (2) and an electrically insulating silicone rubber layer (3) are laminated and has anisotropic conductivity Connector (1), adding a crosslinking component to any one of the two layers of the conductive silicone rubber layer (2) and the electrically insulating silicone rubber layer (3), and adding a curing catalyst to the other layer, through The above-mentioned two layers are stacked and pressed, and at least one of the above-mentioned crosslinking component and curing catalyst diffuses into the other layer and is cured. Accordingly, there are provided a multi-layer connector which cures at room temperature or a temperature close to room temperature, can control the thickness of each layer by proceeding with a slow curing reaction, and has less strain in each layer, and a method for manufacturing the same.
Description
technical field [0001] The present invention relates to a laminated connector with anisotropic conductivity and a manufacturing method thereof, in which a conductive silicone rubber layer and an electrically insulating silicone rubber layer are laminated. Background technique [0002] Conventionally, anisotropy has been used for electrical connection between the glass wiring substrate and the drive substrate of image display elements such as liquid crystal elements (LCD) and electroluminescence (EL) elements, or between the above-mentioned glass wiring substrate and flexible printed substrates. Conductive connectors. The connector includes an anisotropic conductive connector in which insulating rubber and conductive rubber are laminated and integrated, and thin metal wires are arranged in isolation in the insulating rubber, and the thin metal wires penetrate the insulating rubber in the thickness direction. Anisotropic conductive sheet, etc. Among them, for a laminated con...
