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: A device for selectively interconnecting a series of conductors comprises an insulative housing provided with a series of parallel passages through it each adapted to receive a conductive pin whose free end forms the male connection member and whose opposite end is connected to one of the conductors. The various pins all emerge at their free end on a common side of the housing. An insulative cover closes this side of the housing and is provided internally with a plurality of U-shape cross-section conductive bars forming female connection members each facing a plurality of the passages and adapted to cooperate with a plurality of pins by coming into contact with the emergent free ends thereof so as to short-circuit them electrically together.
