Electronic Card Retainer Unit

The retainer unit includes a wire form 10 and formed spring steel retainers 12 which snap over form 10 for the purpose of securing electronic cards 14a, 14b and 14c in place.

Card 14a has a plurality of electronic components 16a and 16b, for example, mounted on it, and has a plurality of sockets 18 fixed on its lower edge. Sockets 18 fit within a connector 20 mounted on a platform 22, and connector 20 has a plurality of upstanding pins 24 that extend into sockets 18 for making electrical connections to components 16a and 16b carried by board 14a. Electronic cards 14b and 14c may have similar electronic components mounted on them, and may have similar electrical connections to them.

Wire form 10, in the form of an oblong, surrounds the upper portions of cards 14a, 14b and 14c. Wire form 10 is supported with respect to platform 22 by legs 26 and 28. Retainers 12 are made of spring steel stock, and each has downwardly depending legs 30 and 32 on its ends. Leg 30 is provided with semi- cylindrical indented portions 30a and 30b, and leg 32 has corresponding indented portions 32a and 32b. A foam rubber strip 34 is fixed on the lower surface of each retainer 12.

Electrical connectors 36 may be used in connection with any of the cards 14a, 14b and 14c. Each connector 36 constitutes a block which rests upon the upper edge of the corresponding card 14a, 14b or 14c, and includes pins 38 extending into the corresponding card 14a, 14b or 14c from the lower surface of the connector. A flat electric cable 40 is connected to each of connectors 36.

In order to assemble cards 14a, 14b and 14c with respect to form 10, each of cards is pushed downwardly to have its plug 18 disposed upon the corresponding connector 20 mounted on platform 22, with pins 24 from the connector 20 extending into the socket holes of the plugs 18. The cards are held fixed in proper positions within form 10 by means of retainers 12 which are spread apart so as to cause the indented portions 30a, 30b, 32a and 32b to embrace form 10 under spring pressure, due to the inherent resiliency of retainers 12. If the cards or edges thereof do not have connectors 36 installed on their upper edges, a retainer 12 is moved downwardly onto form 10 so that it...
