Abstract
A high-performance, multi-row contact matrix electrical connector having a spring element in the form of an elongated hollow split tube with a heat-recoverable member of shape-memory alloy positioned within the tube and including first and second sets of parallel spaced conductors terminating at least at one end thereof in a first and second matrix of contact pads, the matrices and the pads being positioned within the split, a change in temperature changing the shape-memory alloy from one metallurgical state to another, causing movement of the heat-recoverable member and the spring means to open and close the connector.
Claims20
A high-performance connector comprising:
- spring means, said spring means being an elongated hollow split tube having a longitudinal axis and an axially aligned split defining a generally C-shaped cross-section with end portions;
- an elongated and generally C-shaped member concentrically positioned within the cross-section of said spring means and being biased by said spring means, said member changing shape to overcome said biasing of said spring means to change the dimension of said split;
- and
- first and second sets of parallel spaced conductors, each set terminating at one end of each set thereof in a first and a second matrix of contact pads, respectively, the contact pads of each matrix being spaced from each other in that matrix in two dimensions, said first and second sets of conductors at least partially surrounding said spring means and said matrices being positioned within the split of said spring means adjacent the end portions of said spring means, pads of the first matrix being positioned on one side of the split and the pads of the second matrix being positioned generally opposite thereto on the other side of the split, movement of said spring means and said member causing the plurality of pads on each matrix to move toward each other to contact and electrically connect with a substrate that may be inserted within said split.

A high-performance connector comprising:
- spring means, said spring means being an elongated hollow split tube having a longitudinal axis and an axially aligned split defining a generally C-shaped cross-section including arm portions connected to the end portions, the arm portions extending inwardly toward the axis of the split tube, inward closing movement of said spring means causing the arms of said spring means to move toward each other and radially inwardly toward the axis of the spring means causing a wiping action with respect to a substrate that may be inserted within said split;
- an elongated generally C-shaped member concentrically positioned within the cross-section of said spring means and opposing the action of said spring means, said member capable of overcoming the force of said spring means to change the dimension of said split;
- and
- first and second sets of parallel spaced conductors, each set terminating at one end of each set thereof in a first and a second matrix of contact pads, respectively, the contact pads of each matrix being spaced from each other in that matrix in two dimensions, said first and second sets of conductors at least partially surrounding said spring means and said matrices being positioned within the split of said spring means adjacent the end portions of said spring means, pads of the first matrix being positioned on one side of the split and the pads of the second matrix being positioned generally opposite thereto on the other side of the split, movement of said spring means causing the plurality of pads on each matrix to move toward each other to contact and electrically connect with a substrate that may be inserted within said split, said plurality of pads of each matrix moving toward each other and at right angles thereto causing a wiping action with such a substrate.

A high-performance connector comprising:
- an elongated hollow split tube having a longitudinal axis and an axially aligned split defining a generally C-shaped cross-section with end portions;
- means for changing the dimension of said split, said means operatively connected to said split tube;
- and
- first and second sets of parallel spaced conductors, each set terminating at one end of each set thereof in a first and a second matrix of contact pads, respectively, the contact pads of each matrix being spaced from each other in that matrix in two dimensions, said first and second sets of conductors at least partially surrounding said split tube and said matrices being positioned within the split of said split tube adjacent the end portions of said split tube, pads of the first matrix being positioned on one side of the split and the pads of the second matrix being positioned generally opposite thereto on the other side of the split, movement of the split tube causing the plurality of pads on each matrix to move toward each other to contact and electrically connect with a substrate that may be inserted within said split.
