Method of making cartridge connector system

摘要

An improved electronics containing cartridge and cartridge holder are disclosed. The cartridge is utilized to encase electronic circuitry, such as a bubble memory, which can be selectively added to main equipment via the cartridge holder. The cartridge itself is made by an improved system which eliminates the environmental concerns of printed circuit board manufacture. The circuit board of the cartridge is formed by molding a substantially planar member with a plurality of circuit trace forming grooves therein. The circuitry is stamped from a metal web and inserted into the respective grooves. The contacts of the holder and cartridge are arranged for low wear operation. Both of the cartridge and the holder are provided with means which are readily exchangeable and provide a plurality of keyed configurations to assure that only the proper cartridge will be inserted into the respective holder.
