Pitch change connector

Claim 2

An electrical connector comprising an insulating housing having first and second faces, a series of terminals having been stamped from sheet metal stock as identical blanks and each comprising first and second contact portions integrally joined by a deformable strip-like body portion, the terminals being assembled with the housing with the first contact portions arranged at a first pitch at the first face, and the second contact portions arranged at a second pitch at the second face, the second pitch being different from the first pitch, the strip-like body portions having been deformed both longitudinally and laterally in their own planes to change the second contact portions from the first pitch to the second pitch.

Claim 3

An electrical connector according to claim 1 in which the terminals are assembled in the housing with the first contact portions located in coplanar relation at the first face and the second contact portions located in coplanar relation at the second face.

Claim 4

An electrical connector according to claim 2 in which the deformation of the bodies in the lateral direction is in the plane of the strip.

Claim 5

An electrical connector according to any one of claims 1 to 3 in which the first and second contact portions are located in respective rows and the body portions comprise loops extending out of a plane containing the respective rows.

Claim 6

An electrical connector according to claim 4 in which the first contact portions comprise plate portions provided with respective wire receiving slots, and the second contact portions comprise elongate pluggable elements, longitudinal axes of the pluggable elements extending parallel to longitudinal axes of the slots.

Claim 7

An electrical connector according to claim 4 in which a terminal locating block is formed with a first and a second row of cavities arranged at the first and the second pitches, respectively, adjacent the first and second faces, respectively, a first and a second root end of the loop of each terminal being located in corresponding cavities of the first and second row, respectively.

Claim 8

An electrical connector according to claim 6 in which each contact is provided with first and second anchoring portions adjacent the first and second root ends, respectively the anchoring portions being sized for receipt in respective cavities as a close fit.

Claim 9

An electrical connector according to claim 7 in which the terminal locating block is trapped between a cable connecting housing part and a mating housing part, the cable connecting part comprising a pressure plate mounted on a cable supporting portion and defining therewith a cable-receiving aperture, wire connecting portions of the terminals extending through an aperture located centrally of the cable supporting portion into the cable-receiving aperture, the cable supporting portion being integrally formed with a series of hooks aligned with latching apertures formed in the pressure plate in opposite sides of the aperture a series of posts split at free ends upstanding from the cable supporting portion in registration with a series of sockets in the pressure plate having relatively narrow portions and relatively broad portions, the pressure plate being movable towards the cable supporting portion from a cable-receiving position to a cable connection position, the free ends of the posts being receivable in the relatively broad portions of the sockets as an interference fit in the cable receiving position of the connector and in the relatively narrow portions as a force fit in the cable connecting position of the connector and free ends of the hooks penetrating the cable during such movement.

Claim 10

An electrical connector according to claim 8 in which guiding lugs and grooves are provided on the pressure plate and cable supporting surface, the grooves receiving the lugs in sliding engagement during the movement of the pressure plate from the cable receiving condition to the cable connecting condition.

Claim 11

An electrical connector according to claim 9 in which the grooves are blind ended and a stop is provided on the lugs to locate the pressure plate on the cable support.
