Abstract A connector which includes a circuit board wherein the conductive strips thereof are formed of a resilient conductive material and their ends extend past the edges of the supporting board. The circuit board is mounted in a housing which has a plug-receiving recess, and the projecting strips at one end of the circuit board extend into the recess, so that another circuit board can be plugged into the recess to establish contact between the strips of the two circuit boards. The housing can be part of an optical readout head, and the projecting ends of the circuit board which lie opposite those in the plug-receiving recess can support and contact photocells. The circuit board with projecting strips is constructed by adhesively fastening a conductive sheet to an insulative board of smaller length, applying an acid resist in strips to the completely exposed face of the sheet and a continuous coating to the exposed ends of the other face, and etching away the resist-free strips.
An optical readout head comprising: a housing; a circuit board mounted on said housing, said circuit board having a plate of electrically insulative material and a plurality of strips of electrically conductive material, said strips having center portions adhesively fixed to said plate and a first end portions which extend beyond an edge of said plate; a plurality of photocells in said housing, each having a first terminal portion fixed to the first end of a different one of said strips, and a second terminal; conductor means contacting said second terminals of said photocells; and slit means in said housing directing light onto said photocells.

Claim 3
Dependent Claim
56 words
The head described in claim 1 wherein: said housing defines a plug-receiving recess; and said strips have second end portions opposite said first end portions, said second end portions extending past another edge of said plate and into said plug-receiving recess and having their end portions exposed therein for releasable engagement by terminals on a plug.
