  • the insertion member 8 is, in turn, pinched by the two arms 15D of the support 15C, and the piston 15H is in the extended position, so that the part 21E of the fixing means 21 compresses the spring 21G, which has the effect of lowering the ball 21C following the displacement of the inclined ramp 21F.
  • the ball 21C is then embedded in the base 8A or the stud 21A of the insertion member.
  • the jaws 20A and 20B of the gripping means are in the closed position thanks to the action of the torsion spring 25.
  • the body 7 performs, via the base 11C of its mobile assembly 11, a displacement along the axis OZ (FIG. 11A to FIG. 11B), so that the mortise 21B slides on the tenon 21A of the member .
  • the disc 22H of the friction mechanism linked to the intermediate shaft 22B, is applied against the disc 22H linked to the articulation axis 20C.
  • the movement along the axis OZ of said body continues until the spring 22I is compressed by the recoil of the intermediate shaft 22B, since the insertion member 8 is held in position by the arms 15D.
  • the sliding of the shaft 22B on the output shaft 22D of the motor 22A is made possible thanks to the splined connection 22E.
  • FIG. 11B it can be seen that the engagement of the pin 21A of the member 8 in the mortise 21B of the body 7 is such that the ball 21C has crossed the imprint 21D provided in the plate 24 thanks to the out position of said piston 15H.
  • the latter is commanded to move towards its retracted position, then the arms 15D release their pressure on the insertion member which is maintained by the intermediate tenon-mortise connection on the body 7.
  • the base 11C of the movable assembly 11 moves back in the opposite direction along the axis OZ, so that the insertion member 8 is then pushed, by the action of the spring 22I, outwards until that the ball 21C engages in the imprint 21D of the plate 24 under the action of the spring 21G which forces the ball to protrude externally thanks to the inclined ramp of the part 21E.
  • the devices 5, the insertion members of which are locked to the respective bodies, are moved in the direction of the pins 2.1 and 2.2 crimped onto the electrical conductor of the cable 3.1, by virtue of the orders transmitted by the piloting 6 to the corresponding moving parts 11.
  • the jaws 20A and 20B of each insertion member 8 pass from the closed position to the open position, as illustrated with reference to FIG. 8.
  • the electric motor does not -in step 22A, controlled by the unit 6, drives, by the intermediate shaft 22B and the friction discs 22H, the rotation, by the appropriate angle, of the articulation axis 20C, which moves the jaw 20F of the movable jaw 20B of the jaw 20E of the fixed jaw 20A.

More particularly, as shown in FIGS. 15A and 15B, it is assumed, by way of example, that the connectors 4.1 and 4.2 are of the circular type, male and female respectively. Thus, it can be seen in FIG. 15A that one of the male pins 2 is already introduced into its housing 4A while being held there axially, in the usual way, by the elastic tabs 4B1 of a socket 4B which plates the flange 2C of the pin against the shoulder 4C provided in each housing 4A of the connector.
