  • This electrical connector also includes second means for locking known as tilting.
  • the rib of the plug has a width equal to the width of the ramp of the base and its longitudinal axis is inclined relative to the plane of the lower and upper faces of the plug by an angle ( ⁇ , in so that the base and the plug are aligned after locking.
  • the second locking means include a sliding ring mounted on the upper end of the block of the plug and fitted with two lateral tabs of suitable profile and position to each enter the groove of the corresponding ramp. It is provided moreover means for retaining this ring in the active positions and inactive.
  • each contact electric plug is a lyre type blade contact with two branches provided to come into contact on either side of each pin carried by the base.
  • FIG. 1 there is shown a base 10 and a plug 12 in the insertion position.
  • the plug is designed to receive a beam 14 of electrical cables 16 laid out in a sheet for example while the base includes through pins 18, positioned during the molding of said base.

  • One 46, 48 of the ends of each of the ramps opens out at the edge of the housing 22 blind while the other 50, 52 of the ends is through down into the corresponding hole 42, 44.
  • the holes 42, 44 have a particular profile, substantially in the form of rectangle triangle.
  • Each large side 54 and 56 of the right angle is aligned with the edge of each corresponding ramp 38, 40, on the side of the wall 24 plug-in.
  • Each short side 58, 60 is longer than the width of the corresponding groove constituting each ramp.
  • the first means 61 for locking in tilting comprising a notch 62, 64 of locking, in depression.
  • the lower angle 66 of each of the holes which serves as a support is provided with a fillet of radius r .
  • the plug 12 comprises a block 68 of shape partially conjugate with that of the blind housing 22 of the base with two upper faces 69 and lower 70 substantially parallel and two sides 71, 72 lateral guide.
  • This block comprises two sections a ' and b' on its upper face and a single section p ' on its lower face.
  • this block 68 comprises a slot 73 for receiving a bundle 14 of cables 16 electric.
  • the conductive part of each cable is extends into 74 juxtaposed cells.
  • Each cell has a hole 75 for the passage of an electric contact 76 in the form of a blade, comprising each a foot 78 and a head 80.
  • These electrical contacts in the shape of a lyre are held in slots 77 formed in said block, forming a comb and which extend around these lyre-shaped blades, by wrapping sideways to say the least. This arrangement makes it possible to maintain regular space between the blades, keep them rigid for good contact with the pins and isolate them electrically while leaving them pins penetrate to provide electrical connection.
  • Each contact 76 can take two positions, one before mounting, in which the foot 78 of the contact is outside the socket and the other, after mounting, in which the foot 78 of the contact protrudes into the socket 74 to penetrate the conductive part of the corresponding cable and ensure the electrical connection.
  • the foot is generally equipped with harpoons which prohibit removing each blade contact from its slot after assembly.
  • each contact 76 is in lyre shape 82, with two branches 82-1 and 82-2.
  • Each of these branches has a specific lyre type profile which allows, as shown in Figure 5A, a contactless introduction between the lyre-shaped brooch and branches before tipping and contact large and multipoint after failover, as shown in Figures 5B and 5C.
  • the card also carries part of the first means 37 for guiding and locking in the form of two ribs 84, 86.
  • Each rib comprises a straight portion 88, 90 of width equal to the width of the ramps the base, close to the sliding clearance and of length equal at most to that of the larger side 54, 56 of hole 42, 44.
  • One of the ends 92, 94 of each rib is rounded with a radius of curvature equal to r to cooperate with the leave 66 provided in the lower part of the hole.
  • Each rib is provided with a boss 96, 98 intended to cooperate with the notches 62, 64 formed in the base as will be explained later.
  • the rib is spaced from the side wall which carries it.
  • the longitudinal axis of the rib also makes an angle ⁇ with the longitudinal axis 66 of the block 68 whose four faces are substantially parallel two by two if we exclude the sides.
  • ⁇ is slightly rounded with a radius R identical to the radius R of the bottom 32.
  • the base and the plug are also equipped with second means of guide 70, in this case two wings 100, 102 carried by the plug and two grooves 104, 106 formed in the base and of conjugate profile for allow precise positioning. It should indeed limit the game to the penetration so that the lyre-type blade contacts come well, through the two branches 82-1 and 82-2, on either side of pin 18 corresponding.
  • the connector according to the present invention can also be completed by second locking means 108.
  • These second locking means comprise a ring 110 sliding mounted on the upper end of the plug, the remaining end external to the base after fitting.
  • This ring comprises two tabs 112, 114 lateral in profile and position adapted to penetrate each into the groove of the ramp 38, 40 corresponding.
  • This ring can take two positions, one shown in Figure 1A in which the ring is in the high position, inactive, and the other shown on the Figure 1B in which the ring is in the low, active, locking position on tilting, the legs 112, 114 entering the ramps, according to the arrows.
  • means 120 for retaining the second locking means in each of the active and inactive positions comprising a double boss 116, 118 formed inside the ring, and outside the plug, the assembly forming a hard point.
  • the base is considered immobilized in this case, the pins 18 protruding into the blind housing 22.
  • Sheet 12 is inserted in the blind housing and in a first approach, the plug is guided in vertical translation by the ribs 84, 86 which slide in the ramps 38 and 40.
  • the block 68 of the plug is in position tilted.
  • each contact 76 electric lyre type blade comes from either side of the spindle associated by its branches 82-1 and 82-2, this without contact with the spindle.
  • the wings 100 and 102 of the plug complete the guidance by cooperation with the grooves 104 and 106 of the base.
  • the block When the plug is fully fitted into the base with the end of the block against the bottom 32, the block is supported by part of its pan b ' against the pan c of the base and by its pan p' on the pan p of the plug-in face.
  • Each rib 84, 86 is then in line with the hole 42, 44.
  • the block 68 of the plug is operated by tilting according to the arrow in FIG. 5A, that is to say so that the longitudinal axis 66 of the block is coincident with the longitudinal axis of the base, angle ⁇ becoming zero.
  • each rib engages with the notch 62, 64 corresponding to the lateral face 28, 30 of the base. This snap, by its elasticity, allows the operator to feel the maneuver and to perceive that the locking point has been reached.
  • Each electrical contact 76 comes into contact by its branches with the corresponding pin 18 as shown in Figures 5B and 5C.
  • the block 68 is then supported by the sides a ' and b' of its upper face on the sides a and b of the base, which represents a stable support, all the more so as the rear face is supported by its pan p ' on pan q of the base.
  • the first locking means prevent the withdrawal of the plug from of the base.
  • the plug can be returned to the inclined position by reverse tilt, with reduced effort to overcome the hard point constituted by the boss / notch couples, these couples ensuring a brake on inadvertent tilting, in particular caused by vibrations or light shocks.
  • Each leg 112, 114 then enters the ramp 38, 40 corresponding as seen in Figure 1B and the section view in Figure 2.
