Definitions

  • the present invention relates to electrical connectors lockable by push and unlockable by traction on a locking ring of one of the elements of the connector.
  • base and "plug” are used for reasons of convenience. They only involve the base is permanently fixed, although in general it belongs to a fixed device while the plug is connected to a cable.
  • One of the embodiments described in the document already mentioned allows the connector to be coupled by holding the plug either by the body or by the locking ring, which facilitates insertion. But he uses two snaps which engage alternately during insertion operations. At a given time, during insertion, neither of the two snaps is engaged, which creates uncertainty. In most cases it is without disadvantage but we wish to exclude it for applications which require great security.
  • the present invention aims in particular to provide a electrical connector of the type described above, retaining all the benefits you can get but without present its disadvantages.
  • the invention notably proposes a connector electric device according to claim 1.
  • the means elastic can be constituted by springs with tweezers, having curved branches so that they can place these springs in a narrow annular space at inside the locking ring.
  • the ball ring can be made up of several assembled parts, as well than the sleeve.
  • the base A comprises a body 1, the front part of which is constituted by an annular skirt 2 having a shape of revolution.
  • a body 1 In the body is immobilized an insulator 40 pierced of passages 42 for receiving contact terminals 44.
  • the back of the body contains a grommet 46 in which through holes are provided for conductors connected to terminals 44.
  • radial holes in which are trapped balls 3, for example at number of three evenly distributed in the direction circumferential.
  • a crimping does not authorize the balls only to move between an internal position in the radial direction, shown in Figure 1, and a position external in the radial direction, represented in FIGS. 3 and 4.
  • Sheet B also includes a body 4 which contains also an insulator 48 retained in place by a plate 50 and a grommet 52, carrying male terminals.
  • the part front of this body is also tubular and of revolution. It is intended to engage with a small clearance in the skirt 2.
  • annular groove 5 In the outer wall of the plug body 4 is provided an annular groove 5 in a location such that it is in face of the balls 3 when the connector is in a full engagement position ( Figure 4).
  • the plug body 5 has a support flange 10 on an internal shoulder of a locking ring 6.
  • the flange 10 thus limits the movement of the ring locking 6 forwards with respect to the plug body 4.
  • the rearward movement of the ring is limited by means which will be described later.
  • a ball ring 7 In the radial interval between the plug body 4 and the locking ring 6 is arranged a ball ring 7.
  • the ball ring 7 is immobilized in rotation relative to the locking ring 6 by means of sliding keyway, for example having grooves longitudinal 17, formed on the inner face of the ring lock, and keys 18 and 20 belonging to the ball punch ring, which engage in the grooves.
  • the forward movement of the ball ring 7, by compared to the locking ring 6, is limited by its support against a stop 22 which can be constituted by a circlip trapped in a circumferential groove of the locking ring.
  • the ball ring is completed by a socket guide 19 mounted with gentle friction on it and also provided with keys 20. Elastic means tend to push the ball ring 7 towards the stop 22 and the locking ring 6 towards its support position against the flange 10.
  • the elastic means comprise a sleeve which has also for the role of immobilizing the locking ring rotating as long as the connector is not locked and then release it to provide a tactile indication of locking.
  • the sleeve 24 is mounted on the body 4 and has with a sliding keyway, constituted for example by a or internal grooves of the sleeve and one or more keys 26 mounted on the body.
  • a first spring 28, shown in Figure 1 by a double arrow, is interposed between the collar 10 and the sleeve. It tends to repel the sleeve forward.
  • a second spring, shown schematically by a double arrow 30, tends to separate the sleeve from each other 24 and the ball-ring 7.
  • the ball ring 7 is in several parts. It comprises a ring proper 7, to which is fixed the key 18, and a sleeve 34 mounted frictionally soft on the ring proper 7, fitted with the key or keys 20.
  • the springs 28 and 30 are advantageously springs with tweezers of curved shape, which can for example have the appearance shown in Figures 5 and 6.
  • the curvature of the branches ( Figure 5) corresponds approximately to the average radius of the annular space in which it is housed.
  • the springs can have a shape of the kind shown in solid lines in Figure 6.
  • the ball ring can be in two pieces, one carrying the keys 18 and snapping onto the sleeve, the other reduced to a ring 34 for supporting the balls 3.
  • the relative arrangement of the components of the plug remains the same until the ball ring comes into the support position against the balls 3 shown in Figure 2.
  • the locking ring 6 is always immobilized in rotation, given its sliding keying with the ring ball punch 7, itself snapped onto the sleeve 24, itself keyed to the body.
  • Means of coding, no shown, are generally provided on the plug body and the base body to not allow the introduction of the plug only in proper orientation.
  • the balls fade inward under the push of the ring ball punch 7, on which the spring pressure is exerted 28, transmitted by the sleeve 24.
  • the sleeve is dimensioned so that its advance is limited by its coming into abutment against the stop 22 integral with the locking ring 6, itself blocked by the collar 10 ( Figure 4).
  • the spring 30, weaker than spring 28, then takes the relay and projects forward the ball ring 7 which is disengages in rotation from the sleeve.
  • the ball ring 7 is then again in abutment against the stop 22.
  • the balls cannot escape, even when pulled exerted on the plug body.
  • the locking ring is free to rotate and provides status confirmation Locked.
  • Unlocking is carried out by pulling the ring locking 6 towards the rear.
  • the locking ring drives the ball ring which releases the balls.
  • the locking ring cannot move back from the body until it abuts the sleeve 24 against the collar 10. Once the plug is released, it suffices to release the locking ring so that the elements of the plug returns to the position shown in Figure 1.
  • the locking ring is then immobilized again rotating relative to the body.
