置合せ作業が容易となる。Purpose of the Invention The present invention has been made in view of the drawbacks of the conventional electronic component connecting devices described above, and in particular, by connecting a display element and a circuit board with a fully anisotropic conductive sheet by pressure-polymerization contact, The purpose of the present invention is to provide an electronic component connecting device that has a simple and inexpensive structure and is easy to assemble and disassemble. - A liquid crystal display element provided, 3 a circuit board with wiring 4 fully formed on its surface;
Reference numeral 5 denotes a sheet-shaped anisotropic conductive rubber which is polymerized and connected to the connection terminal 2 of the liquid crystal display element 1 and the wiring 4 of the circuit board 3, respectively. The anisotropic conductive rubber 5 is not connected by pressing the upper and lower surfaces thereof into close contact, but by utilizing the close contact of one of the surfaces as shown in FIG. The anisotropic conductive rubber 5 is crimped onto the connection terminal 2 of the liquid crystal display element 1 by a rubber plate 6 that supports the liquid crystal display element, a presser rubber 7, and a presser body 8 that presses these together. On the other hand, anisotropic conductive rubber 5
The circuit board 3 is pressed against the wiring 4 by a presser rubber 9 and a presser rest lO. FIG. 3 is a diagram showing the alignment relationship between (1) the anisotropic conductive rubber 5 and (2) the liquid crystal display element l. The sheet-shaped anisotropic conductive rubber 5 has a base line portion 51 and a connector portion 52. On the other hand, the liquid crystal display element 1 has alignment mark portions 11 in addition to connection terminals 2. Therefore, the base line part 51 is completely aligned with the alignment mark part 11, and the sheet-shaped anisotropic conductive rubber is brought into contact with the connection terminal of the liquid crystal display element and pressed. It becomes easier to align the parts by mixing them.The circuit board 3 side can be constructed in the same way, so a detailed explanation will be omitted.Figure 4 shows another embodiment of the sheet-shaped anisotropic conductive rubber. .Anisotropic conductive rubber 15
has a connector portion consisting of a base line portion 1'5' 1, a conductive ff1152, and an insulating portion 153, and is laminated with insulating layers 154 and 155 in consideration of environmental resistance. This insulating layer is formed by molding by vulcanization or by applying liquid rubber. Therefore, there is no need to require severe skewing of the anisotropic conductive rubber sheet, and the pitch interval between the conductive part 152 and the insulating part 153 is smaller than that of the connecting terminals 2 and 4, which facilitates alignment work.
