Title: Electrical connection structure of conductive transparent body
Inventor: OKUDA MASAMI
IPC: H01L33/00
Filed: 1990-11-22
Abstract: PURPOSE:To connect a conductor wire in a transparent body easily, securely with an external conductor wire by inserting a conductive rubber piece into a hole and inserting a connection pin into the conductive rubber piece. CONSTITUTION:A hole 17 for exposing a conductor wire 15 end is drilled in the base portion 11 into which a connection piece 18 made of a cylindrical conductive rubber is inserted. Further a connection pin 22 is inserted in the center of the connection piece 18. Here the diameter of the connection pin 22 is set to be greater than the difference between the inner diameter of the hole 17 and the outer diameter of the connection piece 18. As a result, the outer diameter of the connection piece 18 is increased to make the connection piece 18 come in press contact with the conductor wire 15 exposed on the inner surface of the hole 17. This makes it possible to easily, securely connect the conductor wire 15 present in a transparent body with an external conductor wire 23.
