Assemblage element for functional unit with card connector means

Claim 2

An assemblage of circuits for mounting a resistive fixed memory consisting of a principal board having a first edge containing means pluggable into an external connector block, said principal board having affixed thereto a pair of connector blocks, each receiving and guiding a removable card-plane bearing two resistor memory planes and disposed toward a second edge opposite to said first edge in a manner that said two card-planes are parallel to said principal board, comprising the improvement wherein: said principal board is longer than the length of said card-planes, and said pair of connector blocks are attached to the same side of the principal board and are so oriented that the direction of plugging in of the card-plane is toward said pair of connector blocks and opposite to the direction of plugging in of the principal board to said external connector block.

Claim 3

The assemblage element of claim 1, wherein said principal board consists of a sheet of insulating material bearing printed circuits on its two faces, and wherein components and modules forming coupling and read amplifier circuits are disposed on the face of said board to which are attached said connectors.

Claim 4

The assemblage element of claim 2, wherein each card-plane is provided with a notch on each lateral edge thereof, and wherein said principal board is provided proximate each lateral edge thereof with a guiding upright which is fitted with a pivotally attached pivoting lever corresponding to one of said notches, said lever having an arm bearing a pin for insertably engaging a corresponding one of said notches of said card-plane, whereby the plugging and unplugging with respect to its connector of a card-plane is effected by simultaneously operating the two corresponding levers.

Claim 5

A circuit board assembly for plugging into an external electrical connector comprising a principal circuit board, said principal board being provided with a row of electrical contacts near one edge thereof for plugging into said external electrical connector, a pair of additional circuit boards, each of said additional boards being provided with a row of electrical contacts, a pair of elongated electrical connectors, each of said elongated electrical connectors mating with a row of contacts on a respective one of said additional boards and supporting said respective additional board parallel to said principal board, wherein the improvement comprises: means mounting said elongated electrical connectors on the same side of said principal board at an edge opposite said one edge, one of said elongated electrical connectors being spaced further from said same side than the other one of said elongated electrical connectors, both of said elongated electrical connectors being oriented to provide for the mating of one of said additional boards therewith in a direction opposite to the direction of mating of said principal board with said external electrical connector.

Claim 6

A circuit board assembly for plugging into an external electrical connector comprising a principal circuit board, said principal board being provided with a row of electrical contacts near one edge thereof for plugging into said external electrical connector, a pair of additional circuit boards, each of said additional boards being provided with a row of electrical contacts, a pair of elongated electrical connectors, each of said elongated electrical connectors mating with a row of contacts on a respective one of said additional boards and supporting said respective additional board parallel to said principal board, wherein the improvement comprises: means mounting said elongated electrical connectors on the same side of said principal board at an edge opposite said one edge, one of said elongated electrical connectors being spaced further from said same side than the other one of said elongated electrical connectors, both of said elongated electrical connectors being oriented to provide for the mating of one of said additional boards therewith in a direction opposite to the direction of mating of said principal board with said external electrical connector.
