Definitions

  • the present invention relates to an electrical connector formed of two parts intended to cooperate with each other by their respective front sides, each of said parts comprising a housing and at least one contact comprising a retaining flange and held in the housing by an insulator in which the contact is plugged in from the rear side and retained by said flange.
  • the present invention aims to provide an electrical connector of simple structure providing, by a particular conformation of the connector, increased security as to the correct insertion of the contacts in the connector parts and this makes contact security significantly improved.
  • the two parts of the insulation must be in the first position, since it is not that in this position that the retention means provided on the rear part allow the passage of the retaining flange every contact.
  • the retention means on the rear part of the insulation include, for each contact, several fingers distributed like petals on a circle, and the housing in the front part of the insulation consists of a recess of revolution able to receive said fingers.
  • said housing is connected to the hole receiving the part of the contact located in front of the retaining flange by a shoulder serving as stop for limiting the insertion depth of the contact.
  • the fingers constituting the retention means can advantageously converge towards their free end and have an interior boss between their location connection to the through hole of the rear part of the insulation and their free end. This boss constitutes a hard point which is clearly noticeable by the operator when plugging in.
  • the means for positioning the two parts of insulating it from each other in the first and in the second reciprocal positions may include latching means made in one piece with said parts.
  • Said positioning means can in particular include on one part of the insulation, a cantilever tab projecting towards the other party and carrying a tooth at its end free and on the other part two transverse notches spaced so as to allow, by bending of said tab, the snap-fastening of the tooth of this last in both of said notches.
  • Said tab can preferably be formed on one of the parts of the insulation so as to flex outwards and in such a position that this bending is prevented by the housing when the two parts of the insulation are mounted in the housing.
  • the connector as illustrated in FIG. 1 comprises a first part 1 and a second part 2, the first part 1 being here a fixed part comprising female contacts 3 and the second part 2 being a movable part carrying male contacts 4.
  • the first part 1 comprises a housing 5 in which the contacts 3 are maintained by an insulator composed of a front part 6 and a rear part 7.
  • the second part 2 comprises a housing 8 in which the contacts 4 are held by a compound insulator a front part 9 and a rear part 10.
  • the housing 8 carries by elsewhere a locking ring 11 which makes it possible to lock the two housings 5 and 8 one on the other, in the coupled position of the two connector parts 1 and 2. This locking is not part of the present invention and will not be described in more detail.
  • the two parts 6, 7 and 9, 10 of the insulation of the two connector parts 1 and 2 are intended for a round connector with two contacts.
  • the two insulating parts 6, 7 of the connector part 1 differ from the two insulating parts 9, 10 of the connector part 2, essentially by the length of the front parts 6, 9 and by the dimensions of the holes provided in these parts 6, 9 to receive, one female contacts 3 and the other male contacts 4.
  • the general structure of parts 6 and 9, 10 on the one hand and 7 and 10, on the other hand is identical, as is the way in which these parts cooperate with each other, with contacts 3, 4 and with boxes 5 and 8. This is the reason why the description that goes follow will be given only for connector part 1, i.e. for parts 3, 5, 6 and 7, but this description applies also to connector part 2, i.e. to parts 4, 8, 9 and 10, respectively.
  • Contact 3 includes, for its maintenance in the part of connector 1, a retaining flange 12 by which the contact 3 is positioned axially with respect to the two parts 6 and 7.
  • the front part 6 has, for each contact 3, an axial hole 13 which receives the part of contact 3 located in front of the flange 12, this hole 13 connecting at the rear, by a shoulder 14, to a tapered enlargement 15.
  • the front part 6 comprises a cylindrical front portion 16 to which it is connected, towards the rear, via a shoulder 17, a portion 18 cylindrical of increased diameter, carrying three bosses 19 distributed at 120 ° from each other.
  • three legs 20 in overhangs protrude rearward, each of these legs 19 bearing at its free end an inner tooth 21 of trapezoidal shape.
  • the rear part 7 comprises, for each contact 3, a hole for cylindrical passage 22 extended forwards by four fingers 23 in cantilevered.
  • the diameter of the hole 22 is very slightly greater than the diameter of the collar 12 of the contacts 3 and the fingers 23 converge so that the reciprocal distance of the fingers 23 opposite to the free ends of the latter, corresponds substantially to the diameter of the part of contact 3 located behind the flange 12.
  • Each finger 23 also has, on the inner side, a boss 24 between its connection to the rear part 7 and its free end.
  • the rear part 7 has a lateral surface cylindrical having the same diameter as the portion 18 of the portion before 6, but with three notches 25 which correspond to the three legs 20 of the front part 6 and have a notch 26 whose profile corresponds to the shape of the tooth 21, and a rear flank 27.
  • the rear part 7 has, in its lateral surface outside, in three places offset from the notches 25, three locking tabs 28 projecting rearwardly and having an outer shoulder 29 by which the legs 28 can be supported in a groove 30 of the housing 5 in the position according to Figure 1, position in which the cylindrical portion 16 of the front part 6 is fully engaged in the front portion 31 cylindrical housing 5, its shoulder 17 bearing against a shoulder 32 of the housing 5.
  • the two parts 6 and 7 of the insulation are spaced from each other, this position being defined by latching of tooth 21 of lugs 20 of part 6 in notch 26 notches 25 of part 7.
  • the fingers 23 are clear of housing 15.
  • Contacts 3 can be engaged from the rear, through the holes 22 of the rear part 7 until the flanges 12 come to bear against the bosses 24 of the fingers 23 ( Figure 4), which constitute a clearly perceptible hard point.
  • the two connector parts 1 and 2 can be coupled and locked in the coupled state using the ring 11, as illustrated by figure 1.
  • the connector part 1 could comprise by example of male contacts instead of female contacts, or male contacts and female contacts, the other connector part 2 with additional contacts.
  • the connector could also be a non-circular connector and the number of contacts could be different from two.
  • a considerable advantage of the embodiment shown and described consists in the fact that all parts of the connector and particular the two parts 6, 7 and 9, 10 of each connector part 1, 2, can be made of plastic by simple molding, without resuming machining. Each connector half is made up like this a minimum number of simple manufacturing parts, which reduces the cost of the connector as a whole.
