が得られるものであれば部材の選択は自由である。Next, the present invention will be explained in detail based on an embodiment shown in the drawings. The reference numeral 1 in FIG. 1 is a connector, and this connector 1 is formed by laminating a conductive layer 2 and a metal layer 1113, which is the same as in the conventional example. The conductive layer 2 is made of metal foil such as stainless steel or phosphor bronze, and the insulating layer 3 is made of styrene-butadiene-styrene (SBS), styrene-ethylenebutylene-styrene (SEBS), or ethylene-vinyl acetate copolymer. (EVA) type or other thermoplastic elastomer film is adopted, and in addition, an adhesive layer 4 made of a modified thermoplastic elastomer is used between the two, that is, the conductive layer 2 and the insulating layer 3 to increase the bonding strength between the two. It is assumed that it will be established in Below, each layer described above will be explained in more detail.
The conductive layer 2 is a metal foil made of the above-mentioned material, and the thickness of the foil is currently about 0.0005 mm, which is easily available on the market. It is a good idea to select it appropriately. Similarly, the thermoplastic elastomer film used for the insulating layer 3 is currently available with a thickness of 0.02 to 0.1 mm, and the material and thickness are appropriately selected according to similar conditions. The adhesive layer 4 newly provided according to the present invention is the insulating layer 3
It is preferable that the adhesive is of the same quality as the member adopted as the material. For example, if an SBS-based material is selected, the adhesive is a thermoplastic elastomer modified with hydromaleic acid, and the specific material is is provided on both surfaces of the conductive layer 2 by means of coating or the like, and serves to strengthen the bond between the conductive layer 2 and the insulating layer 3. To explain the connector 1 of the present invention having the above-mentioned structure using more specific numerical values, for example, the conductive layer 2 is 0.00
A 5 mm metal foil is adopted, an insulating layer of 3kno, a thermoplastic elastomer film of 02■■ is adopted, and the adhesive layer 4 is
Since is a coating film, if we assume that the dimensions can be ignored, then
The connector 1 of the present invention has a pitch of 40 pieces/dragon, and compared to the conventional example where the limit is 5/1 to 10 pieces/dragon, a much finer pitch can be obtained. Therefore, due to the action of the adhesive layer 4, the respective layers, that is, the conductive layer 2 and the insulating layer 3, do not peel off. Next, a method for manufacturing the connector 1 having the above structure will be explained based on the process diagram shown in FIG. First, if SBS-based thermoplastic elastomer is selected as an insulating layer on both sides of a metal foil such as stainless steel having appropriate dimensions and thickness, the SBS-based thermoplastic elastomer is modified with hydromaleic acid. A film is formed by coating a thermoplastic elastomer dissolved in a solvent such as an organic solution. A separately prepared thermoplastic elastomer is made to have a desired thickness by, for example, calendering, and is cut into appropriate dimensions to form a film, and then cut into the required number with the metal foil on which the coating has been formed. Lamination is performed, heating is performed to a temperature close to the melting point of the thermoplastic elastomer, and at the same time pressurization is performed. In the heating step described above, the solvent in the coating evaporates and scatters, leaving only the modified thermoplastic elastomer as the coating, and further heating turns the modified thermoplastic elastomer into a molten state. In this state, the modified thermoplastic elastomer has strong adhesion to both the metal side and the thermoplastic elastomer side, so that the two will be firmly adhered after cooling. The connector 1 of the present invention can be obtained by cutting the material obtained through the above steps into appropriate shapes perpendicular to the laminated surface, and as explained above, the connector 1 is made of metal that will become the conductive layer 2. It goes without saying that depending on the selection of the foil and the thermoplastic elastomer film that will serve as the insulating layer 3, it is possible to have an extremely fine pitch. In this example, stainless steel was used as the metal foil and SBS type was used as the film, but the present invention is not limited to the above-mentioned members only, and any material that can obtain the same performance as the above-mentioned members may be used. The selection of members is free.

るものである。As explained above, the present invention provides a connector characterized by alternately laminating metal foil conductive layers such as stainless steel and thermoplastic elastomer insulating layers, so that the conductive layers and the insulating layers are stacked alternately. Both of these features can be made dramatically thinner than conventional rubber-based products, and as a result, the connectors can be made with extremely fine pitches, meeting market demands. At this time, by providing a manufacturing method in which a metal foil conductive layer made of stainless steel or the like is coated with a modified thermoplastic elastomer adhesive layer on both sides, peeling between the conductive layer and the insulating layer can be avoided. It also has the excellent effect of increasing the reliability of the connector.
