The part of each passage between the insertion end and the slot includes a recess the depth of which increases in the direction towards the slot and wherein the retaining tongue is housed.

Abstract: A system is provided for polarizing electrical connectors of generally parallelepipedal shape and of the type having a male housing part adapted to be inserted in a skirt of a female housing part, one of these parts having along one wall at least one longitudinal tongue and the other of these parts having at least one corresponding groove which receives the tongue when the male housing part is fitted into the skirt of the female housing part. The free end of the tongue terminates in a bevel, the free edge of the skirt terminates in a corresponding bevel and the bevels on the tongue and on the free edge of the skirt are oriented so that, if the male housing part is not offered up in the correct position for insertion into the skirt, the bevels bear one against the other and tend to close up the opening of the skirt.

Abstract: Device for coupling two electrical connector housing members includes two toothed sectors on one member, each sector including a slot leading to a cam. The cams cooperate with two lugs on the other member. The sectors are rotated to occupy either an open first position or a locked second position.

Abstract: An electrical connection system includes a frame, a main printed circuit "mother board", a series of secondary printed circuit "daughter boards", and interconnecting spacers formed of an insulative material plate with holes in it into each of which is inserted a buffer that is a good conductor of electricity. The frame includes a support plate with series of slides, the mother board resting on the support plate and receiving the interconnecting spacer. The daughter boards are slid into the slides and include, along an edge which cooperates with the interconnecting spacer, a heel-piece on which is mounted and to which is fixed a flexible printed circuit the tracks of which are connected to those of the daughter board and cooperate with the buffers. Arrangements are provided to fix the daughter boards to the frame.

Abstract: An electrical connector comprises a male member with conduits arranged in rows and in transverse lines and each designed to receive an electrical contact member. The electrical contact members are locked by a locking key mobile in the male member perpendicularly to the conduits and having slots corresponding to the rows. The key includes notches in the slots and disposed along the transverse lines. The male member and the key carry markers corresponding to the rows and to the transverse lines.

Abstract: An electric connector includes a female housing member and a male housing member and each housing member includes an arrangement for receiving a locking key able to assume two positions. These are a waiting position allowing insertion of the members and a locked position in which the locking keys lock the members. Each locking key includes means for opposing insertion of the male housing member into the female housing member when it is in the waiting position.

Abstract: An electrical connector housing member includes a body with passages to receive a contact member and a locking key with protuberances which engage in slots opening into the passages. The width of the protuberances is equal to the dimension of the slots which extend the full width of the passages and the protuberances are extended by bosses.

Abstract: An electrical connector housing element includes passages each receiving an electrical contact and a system for locking them. The passages are in two series each comprising two rows. The locking system includes two keys in a head-to-tail arrangement and each of which is U-shape with two branches and a core. Each key is mounted so that one of its branches lies between the branches of the other key. Inclined guides are provided in a groove whereby each key can move in the groove in two perpendicular directions. In a locking position the two branches of the first key immobilize the electrical contacts of the two first rows of the two series of passages. In the locking position the two branches of the second key immobilize the electrical contacts of the two second rows of the two series of passages.

Abstract: Female electric contact member includes a first part having crimping lugs at one end extended by a profiled part in turn extended by a body ending in two elastic bars which form a clamp for gripping a corresponding male electric contact. A complementary part fixed to the body includes two elastic bars to strengthen the elastic action of the bars. The body of the first part has a circular cross-section, the complementary part having a corresponding circular cross-section and, along each of two opposite edges which are contiguous after bending, a lug adapted to be inserted in a slot in the body of the first part and a cut-out lug at an intermediate point of its surface which is inserted in a slot of the first part.

Abstract: A hermaphroditic electrical contact member has a channel section body having a floor wall extended to form a male tongue, two lateral walls and a ceiling wall.
