[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elastic connector which is useful for connecting by, for example, placing it between a wiring of a glass substrate of a liquid crystal display and an electrode of a printed circuit board and making a pressure contact in a conductive direction, and a method for manufacturing the same. More specifically, one of the warp yarns or the weft yarns is a conductive yarn, and the cloth is covered with any insulating polymer having low temperature resistance, flame retardancy, flame retardancy and heat dissipation, and solvent resistance. In addition, the present invention relates to an elastic connector having conductive threads protruding from the surface of an insulating polymer and a method for manufacturing the same.

[0002]

2. Description of the Related Art Heretofore, there have been proposed some elastic connectors used for connecting a wiring of a glass substrate of a liquid crystal display and a printed circuit board.
For example, there are the following proposals as a connector and a manufacturing method in which a woven fabric in which one of a warp yarn and a weft yarn is a conductive yarn and the other is an electrically insulating yarn is coated with an insulating polymer. (1) A substantially cubic rubber or thermoplastic elastomer in which a plurality of conductive thin wires interlaced with an insulating thin wire are present on two opposite sides (JP-A-3-208271). (2) A multi-terminal connector (Japanese Patent Laid-Open No. 59-151783) in which both ends of a conductor of a mesh-like mesh body in which a conductor is a warp yarn and an insulator is a weft yarn are plated with metal. (3) An insulating layer is formed on the surface of a net made of conductive fibers as warp yarns and insulating fibers as weft yarns, and a predetermined number of these layers are laminated and integrally joined, and the composite is formed in the lengthwise direction of the warp yarns. On the other hand, a method for producing an anisotropically conductive elastomer sheet produced by slicing in a direction perpendicular to that (Japanese Patent Laid-Open No. 61-179014)
Issue).

[0003]

However, in the methods disclosed in Japanese Patent Laid-Open Nos. 3-208271 and 61-179014, the conductive thread does not protrude from the insulating polymer body and is pressed against the adherend. At times, the conductive thread is only in surface contact with the adherend electrode, and there is a problem that sufficient performance cannot be maintained in terms of conduction reliability.

Further, in a connector in which a woven fabric in which one of the warp yarn and the weft yarn is a conductive yarn and the other is an electrically insulating yarn is coated with an insulating polymer, is the warp pitch interval and the weft pitch interval equal? , If it is close to it,
Since the electrically conductive thread is firmly held by the electrically conductive thread, the electrically conductive thread itself does not have flexibility, and the conductive thread bends at the connection part with the adherend during pressure contact in the conduction direction, resulting in a connection. There is a common problem in the characteristics of the woven fabric that the resistance value increases and a short circuit occurs due to the breakage of the conductive thread between the electrodes of the adherend.

Further, in the method disclosed in Japanese Patent Laid-Open No. 3-208271, the woven fabric is sandwiched between sheets formed of a thermoplastic elastomer, and internal stress during heating under pressure causes disorder in the woven fabric arrangement interval. The arrangement intervals may not be equal or the conductive threads may contact each other,
There was a limit to the insulation, and there was a problem with high-definition connections.

Further, JP-A-59-151783 has a problem in that a connection method such as soldering must be taken between the conductor of the connector and the adherend such as a printed circuit board.

Further, according to the manufacturing method of Japanese Patent Laid-Open No. 61-179014, the sheet-like insulating polymer material interposed between the woven fabrics has a large thickness of 0.4 mm and is sliced from the composite. The anisotropic conductive elastomer sheet obtained is
High-definition electrode with two or more adherends (typically 5 / m
There is a problem that it is not suitable for pressure contact conduction to a substrate having a thickness of m or more).

Further, since the conventional elastic connector has a complicated manufacturing process, the selectivity of the insulating polymer is limited, and low temperature resistance, flame retardancy, flame retardancy and heat dissipation, and solvent resistance. It was difficult to freely select an insulating polymer body having durability suitable for the intended use. Therefore, there are many restrictions on the usage environment of the elastic connector.

In order to solve the above-mentioned conventional problems, it is an object of the present invention to provide a conductive elastic connector which has high conduction reliability, high density and is easy to manufacture, and a manufacturing method thereof.

[0010]

It is preferably an elastomer.

Further, in the above-mentioned structure, a structure in which both ends of the conductive thread are projected from the surface of the insulating polymer elastic body,
It is preferable that the insulating polymer elastic body is contracted.

Next, in the method for producing a conductive elastic connector of the present invention, a high-density woven fabric in which one of the warp threads or the weft threads is a conductive thread and the other is an electrically insulating thread is present in the insulating polymer elastic body. A method of manufacturing a connector, wherein the high-density fabric is sandwiched by using an insulating polymer elastic body containing a shrinking component, or the insulating polymer elastic body containing a shrinking component and the high-density fabric are laminated, Then, the insulating polymer elastic body is subjected to a shrinking treatment.

In the above structure, it is preferable that the insulating polymer elastic body is contracted by heat treatment.

As the shrinking agent, a known compound such as a dialkylcyclic compound, polyethylene, polymethylmethacrylate, or a silicone-based thermoplastic resin can be used.

Secondary vulcanization is performed using a hot air oven, and then cutting processing is performed to obtain an elastic connector. Further, for low temperature resistance, for example, methyl phenyl vinyl silicone in which a part of the methyl group of silicone rubber is changed to phenyl group may be used, and for imparting flame retardancy, for example, silicone rubber may be a Pt compound, It suffices to add titanium oxide or the like. In order to impart flame retardancy and heat dissipation, for example, a Pt compound, silicone rubber flame-retarded with titanium oxide, or a metal oxide such as aluminum oxide or magnesium oxide, It suffices to add a non-oxide such as aluminum nitride or boron nitride.
