Abstract
An automatic switching matrix that includes an apertured matrix board containing a matrix of wires that can be interconnected at each aperture. Each aperture has associated therewith a conductive pin which, when fully inserted into the associated aperture, effects electrical connection between the wires within that particular aperture. Means is provided for automatically inserting the pins in a determined pattern and for removing all the pins to permit other interconnecting patterns.
Claims2
An automatic switching matrix that comprises, in combination
- (a) an apertured matrix board comprising a matrix of intersecting conductors that can be interconnected at any intersection thereof, the matrix board having apertures that extend from one major surface to the other major surface thereof, each aperture mating with an intersection of intersecting conductors;
- (b) a plurality of conductive connection pins, one such pin being disposed to register with each aperture and initially out of contact with the conductors located in the associated aperture;
- (c) means for automatically depressing individual connection pins into selected apertures, which automatic depressing means comprises:
- (i) an x-y positioning mechanism and
- (ii) an electro-mechanical pin depressing mechanism which is positioned, automatically, by the x-y positioning mechanism;
- and
- (d) an automatic reset mechanism that forces the connection pins from apertures in which they are inserted, which the automatic reset mechanism comprises a knock-out board containing a plurality of reset pins, each such reset pin being located to register with an aperture in the matrix board, and means to move the knockout board toward the matrix board so that the reset pins will enter the matrix board and push the conductive connection pins out of the electrical connection with the conductors in the corresponding hole.
