Apparatus for the mounting and wiring of printed circuit boards

Abstract From the Canadian patent

An apparatus adapted for the mounting and wiring of printed circuit boards includes front and rear supports which together define paired slots into which the circuit boards are receivable and thus transversely mountable relative thereto so as to maintain the boards in a substantially parallel spaced apart relationship to one another. The boards can be securely locked in the mounted positions by a resilient ring or like structure which seats in a circumferential slot defined in the front and rear supports supports. An end bell housing is also disclosed whereby various electrical components can be assembled with the circuit boards by virtue of the locking engagement established with the rear …
