Claims6
An electrical equipment unit comprising:
- a box-like case;
- a flexible printed circuit having a flexible portion and at least one portion thereof rigidized to provide an integral, planar board-like portion adapted to support electrical components thereon, said flexible circuit having conductive tracks covered by insulation;
- means mounting said circuit within said case, said means cooperating with and supporting said board-like portion within said case;
- a hole formed in one side of said case;
- said flexible portion of said circuit extending across said hole in generally parallel relation to said side;
- the insulation on the surface of said flexible portion facing said hole being removed to provide bare conductive tracks thereat;
- a connector device removably mounted on said one side of said case over said hole;
- means on said connector device for supporting a flexible circuit on the surface of said device overlying said hole;
- and
- spring means in said case urging said flexible portion of said flexible printed circuit outwardly toward said surface of said connector device for electrically engaging said flexible portion to a flexible circuit on said surface.
