Abstract

This is an application of a conductive metal powder particle connector, wherein one or more insertable printed circuit cards or boards are assembled in an end-two-end relationship. The two-end relationship permits a doubling of the number of contacts in the assembly.

Conductive Metal Powder Electrical Connector

This is an application of a conductive metal powder particle connector, wherein one or more insertable printed circuit cards or boards are assembled in an end-two-end relationship. The two-end relationship permits a doubling of the number of contacts in the assembly.

The card assembly comprises a card 1 which has pin carrying substrates 2 attached to it at both ends of the card. The pins 3 on one side of the substrate are electrically connected to the tabs 4 on the card 1 by either solder reflow, bonding or similar process. At the other end of the pins 3, the substrate 2 has a holder 5 containing conductive metal powder particles 6 and into which the pins 3 are plugged to complete the card assembly.

The card assembly is then transversely inserted between two sets of printed circuit boards 7 and located between guides 8 that are a part of the board assembly. When the card assembly is in position, the substrates 2, containing the conductive metal powder 6, are moved toward the boards 7 so as to mate with the assigned pins 9 which are integral with boards 7. When the powder containing substrates 2 are actuated and flush with the boards 7, as shown in Fig. 2, the conductive powder 6 is in contact with the pins 3 in the card assembly and the pins 9 in the board assembly, thereby completing the electrical circuits. To remove the card assembly, the reverse procedure is followed.
