Definitions

  • the invention relates to an electrical connector.
  • the electrical connectors generally consist of a base and a plug on which a lock is mounted for free rotation.
  • the plug and the base each consist of a metal body of generally cylindrical shape, inside which is housed an insert of insulating material receiving the male or female connection pins.
  • the plug body and the base body are each provided with complementary longitudinal grooves intended to ensure the angular positioning of the plug relative to the base, during their assembly, and so that each male pin is assembled with its pin. corresponding female.
  • the assembly of the plug on the base is obtained by screwing a thread, provided on the internal face of the lock, with a complementary thread provided on the external face of the base.
  • this known embodiment if it is effective in preventing untimely unscrewing of the lock, nevertheless has various drawbacks and, in particular, the operation of the lock is unpleasant because the notches act throughout the duration of rotation of the lock on the plug. Furthermore, because this notching exists during the entire duration of rotation of the lock, the locking position is poorly defined as a result of too many lock latching positions, so that the operator can stop the screwing the lock while the plug is not fully inserted into the base or, on the contrary, force the screwing of this lock while the plug is already fully pressed on the base.
  • the present invention aims in particular to remedy these drawbacks and for this purpose relates to an electrical connector comprising a socket and a plug consisting of a socket body and a plug body each receiving an insert of insulating material provided , one of male pins, the other of female connection pins, complementary grooves and ribs on the plug and socket bodies to position them angularly during their assembly by axial displacement, a lock mounted to rotate on a shoulder of the plug body, this lock being provided with a thread which engages, during assembly of the connector, on a corresponding thread of the base body, the plug body and the lock further comprising, one a circular alignment of notches, the other an axially movable ring provided with at least one complementary notch called finger oriented towards the alignment of notches, elastic means being provided to cooperate with the ring and maintain, in the position of non-assembly of the connector, the finger separated from the alignment of notches, this ring and these elastic means being disposed on the path of the base body in order to push elastically, at
  • the ring is arranged axially between two elastic means.
  • the alignment of notches is provided on an internal rim of the lock, while the ring and the elastic means are arranged on the plug body so that the base body can push the finger towards the notches at the end of assembly of the connector.
  • the alignment of the notches provided on the internal rim of the lock, on the one hand, and the ring as well as the elastic means mounted on the plug body, on the other hand are arranged to on either side of the shoulder of the plug body, the finger being permanently held in a notch in the shoulder of the plug body.
  • the alignment of notches on the one hand, and the finger on the other hand are provided facing one another, one on the shoulder of the plug body , the other on an axially movable ring provided on the latch between two elastic means to be located on the path of the base body during assembly of the connector.
  • the present invention therefore aims to achieve a connector which is maneuverable, which allows to highlight the position connector assembly and which also makes it possible to avoid separation of the two parts of the connector when they are subjected to vibrations.
  • the connector comprises a base 1 and a plug 2.
  • the base and the plug each comprise a base body 3 and a plug body 4, preferably metallic, to the 'inside which is housed an insert of insulating material, respectively 5 and 6, these inserts receiving, one the male pins 7, the other the female pins 8 for connection.
  • the plug body 4 has a shoulder 9 against which is freely rotatable a lock 10 provided with an internal thread 101 cooperating with a thread 31 provided on the base body 3.
  • the latch 10 is supported on the shoulder 9 by means of an insert 102 fixed by screwing, crimping or any other means to the latch.
  • the latch 10 is held on the plug body 4 between the shoulder 9 and a split elastic washer 11 housed in a groove.
  • This insert 102 fixed to the lock 10 is made of hard metal and has a circular alignment of notches 12. Furthermore, the plug body 4 has a ring 13 (see also FIG. 5) which is provided with three fingers 14 oriented towards the circular alignment of notches 12.
  • the fingers 14 are each housed in free sliding in a notch 91 of the shoulder 9, so that the end of these fingers can be received between the notches of the alignment of notches 12.
  • the ring 13 is disposed between two corrugated spring metal washers 15 and 16, one 15 being disposed between the ring 13 and the shoulder 9, the other 16 being disposed between the ring 13 and a second ring 17 (see also figure 4).
  • the plug body 4 has on its outer face, longitudinal ribs 18 which correspond to grooves 19 formed on the internal wall of the plug body 3, these grooves and ribs forming keying grooves allowing the axial assembly of the body of plug 4 on the base body 3, in a single angular position, for which each male pin 7 is arranged in the axis of its female pin 8.
  • these include notches 20 corresponding in number, position and dimensions to those of the ribs 18.
  • the offset of the fingers 14 and the notches 20 of the ring 13, will be different from the offset of the notches 91 and the ribs 18, in order to avoid surely that the notches 20 can return to be placed in the alignment of the ribs 18 when the fingers 14 are arranged in the notches 91 of the shoulder 9.
  • the spring washer 15 is preferably of a weaker force than that of the washer 16.
  • the stack of rings and washers 13, 15, 16, 17 which projects outside the grooves 18, is disposed on the path of the base body 3 during assembly of the connector.
  • the ribs 18 are first introduced into the grooves 19 then the plug body moves axially towards the base body, while the 101 thread of the latch 10 cooperates with the thread 31 of the base body 3.
  • the male pins 7 penetrate into the female pins 8 then the free end of the base body 3 comes to bear on the ring 17 for push the assembly of the two rings 16, 17 and the two washers 15, 16 towards the shoulder 9 so as to slide the fingers 14 in the notches 91 towards the notches 12.
  • the washer 15 compresses since it has a lower elastic force than that of the washer 16 and then at the end of screwing the lock on the base body , the end of the fingers 14 penetrates between the notches of the alignment of notches 12, so that the final rotation of the latch 10 to produce the end of the screwing and the end of the assembly of the plug on the connector, is felt by the operator both mechanically and auditively.
  • the dimensions of the notches, fingers and springs may, for example, be determined to produce, at the end of assembly, four mechanical and sound clicks of increasing force thus perfectly demonstrating the correct assembly of the connector, the cooperation of the fingers and notches making it possible, moreover, to avoid the inadvertent unscrewing of the lock 10 during vibrations and, therefore, the separation of the plug and the base.
  • the plug body and the lock comprise, one an alignment of notches, the other at least one finger.
  • notch and “finger” are only used for reasons of language terminology because the notches and the fingers can be replaced by each other, this connector can also implement two alignments circular notches.
  • the ring 13 may include an outer ring provided with notches, capable of passing over the shoulder 9 in order to come to engage on the fingers (or notches) 12 In this case, this axially movable ring 13 will be immobilized in rotation by complementary ribs and grooves provided on the plug body.
  • the ring 13 axially movable is mounted on the plug body, while the circular alignment of notches (or fingers) is provided on the latch.
  • a reverse construction may however be provided as shown in FIG. 3.
  • the shoulder 9 of the base comprises fingers or a circular alignment of notches 21 arranged opposite a circular alignment of notches (or fingers) 22, provided facing a ring 23.
  • This ring 23 has, at its periphery, notches which are housed on grooves 24 provided on the internal face of the lock 10 so that this ring 23 can move axially relative to the lock, while being immobilized in rotation.
  • the latch 10 has an internal end flange 25 which is attached and fixed, for example by screwing, in order to allow the establishment of the ring 23 on the grooves 24.
  • the ring 23 is disposed between two elastic means constituted, in this example, by a coil spring 26 disposed between the shoulder 9 and the ring 23 and by a corrugated washer made of spring steel 27 disposed between the ring 23 and a second ring 28 intended to receive, in support, the end of the base body 3.
  • This second ring 27 can be mounted either on the latch 10 like the ring 23, or on the plug body 4 like the ring 17 in the example of Figures 1 and 2.
  • this connector is similar to that of FIGS. 1 and 2 and it can be seen that, when the bolt 10 is screwed in order to push the plug body 4 axially into the socket body 3 and electrically connect the male and female pins , the end of the base body 3 comes to bear on the ring 27 in order to push the ring 23 first, towards the shoulder 9, against the spring 26.
  • the return spring 26, which is weaker than the spring 27, is compressed, the fingers and notches 21 and 22 engage with each other at the end of the assembly of the connector and the rotation of the latch 10 then continues while producing clicks mechanical and sound increasing as a function of the compression of the spring 27 by the base 3.
