US 5,470,245 A · Electrical connector having flat and elastic multi-contact members

Abstract

In a connector for use in connection between a pair of connection objects opposite to each other, each having a number of contact holes arranged in rows and columns in a contact matrix, a plurality of flat and elastic multi-contact members are used for connecting contacts in the contact holes of one connection object with contacts in the contact holes of the other connection object. Each of the multi-contact members comprises a flexible and flat insulator sheet and conductive layers formed on opposite surfaces of the sheet. At least one of the conductive layers are separated into a plurality of conductive strips corresponding to contact holes in one row of the contact matrix. The conductive strips are fitted into contact holes in the corresponding row of contact matrix at opposite ends of each of the multi-contact members. When the connection objects are relatively moved in the direction perpendicular to the first direction and the rows, the opposite ends of the conductive strips are brought into press contact with contact elements in the contact holes due to elastic deformation of the multi-contact member. One of the conductive layers on the opposite surfaces of the sheet can be an integral film overlying the corresponding surface. In that case, one of two contact elements in each of contact holes is used as ground contact to be brought into contact with the integral film.
