Abstract: An electrical connector comprises an insulating housing having a transversal partition formed with mutually parallel passages for receiving electrical terminals, and a retention plate insertable into the housing up to a front position in which it is retained against the partition. The plate is formed with terminal-receiving holes distributed in the same array as the passages. They extend forwardly as resilient fingers adapted for snap-fastening connection with the terminals. The fingers are adapted to the shape of the passages so that they can penetrate into a passage and be retained therein in the position where they hold the terminals when the retention plate is in its front position. Each hole is formed with a rearwardly-directed shoulder for abutment with a corresponding step on the respective terminal. The abutment shoulder is placed so as to stop the terminal in the position where the fingers are snapped onto them.

Abstract: An electric test connector is arranged for temporary for connection with another connector, for checking the electric continuity of units connected to the other connector. It comprises: a pluggable casing and a lock carried by the casing and arranged for retaining the other connector. An electrically insulating plate is movable in the casing along the plugging direction and arranged for abutting connection with the front face of the other connector. The plate is resiliently biased. Electrical contact pins carried by said plate are resiliently biased forwardly towards a position where they have a predetermined amount of projection with respect to the plate. The pins are distributed according to a predetermined pattern corresponding to that of electrical contacts in the other connector.
