Definitions

  • the invention relates to improvements to the elements of electrical connector housings.
  • the invention relates to electrical connectors comprising two housing elements, a female intended to receive a male element, each element comprising one or more channels each intended to receive an electrical contact member, the electrical contact members of one elements being complementary to those of the other and each electrical contact member being crimped at one end of an electrical conductor.
  • One of the aims of the present invention is to allow a much simpler plugging and which can be carried out directly during the mounting of the electrical contact members in the channels of the housing elements.
  • the improvements which are the subject of the invention relate to elements of electrical connector housings of the type comprising a body having, at least, a channel intended to receive, at least, an electrical contact member set at one end with a conductor and comprising in the channel means for locking said electrical contact member and a cover intended to be mounted on a rear end of the body and having on its bottom, at least, a hole for the passage of the conductor and sealing means from the rear end of the body, said improvements being characterized in that the cover is partly filled with a self-healing plastic material and means are provided for maintaining said cover in a first waiting position in which it is distant from the rear end of the body and in which the the electrical contact member can be engaged in the hole in the bottom of the cover through the self-healing material to be put in place in the channel and in a second locking position in which, after the contact member has been put in place, the self-healing material is compressed between the bottom of the cover and the rear end of said body.
  • self-healing plastic material is meant a material capable of being deformed or perforated and which tends to return to its initial shape.
  • the cover being in its standby position, the electrical contact member is engaged in the hole in the bottom of the cover, said member perforating the self-healing material and coming to lock in the channel then the cover is pushed. towards its locking position, the material returning to its initial position by enclosing the conductor, and being gripped between the rear end of the body and the bottom of the cover to ensure a tight closure of said rear end.
  • the body has on its side wall, at least two teeth, one of which is located in the vicinity of the rear end and the other offset towards the other end of said body, while the cover has a skirt intended to engage on the body and in which is cut, at least one elastic tongue having, on its internal face, a hook intended to cooperate, selectively, with the teeth to maintain the cover in the two positions.
  • the channel on the side of the rear end of the body, has a flared part forming a ramp
  • the cover comprises, erecting from its bottom, a plate intended to cooperate with the ramp in order to be guided towards one end of the contact member.
  • Figure 1 is an exploded perspective view of a housing element of a connector, according to the invention.
  • Figure 2 shows, in exploded perspective, an alternative embodiment of the invention.
  • FIGS 3, 4 and 5 are sectional views showing the establishment of an electrical contact member in the housing member.
  • a male housing element intended to cooperate with a corresponding female housing element. It is obvious that the invention applies both to a male housing element and to a female housing element. Also in the embodiments shown, the electrical contact member is female, but it could perfectly well be male or hermaphrodite. Finally, the housing element shown in the drawings is one-way, but it could perfectly well be several-way.
  • the housing element of FIG. 1 comprises a main body 1 and a cover 2.
  • the body 1 is cylindrical and has a channel 3 intended to receive a female electrical contact member 4 crimped at the end of an electrical conductor 5 and having, at the end opposite the conductor, an elastic clamp 6 intended to receive a male tongue, one of the side walls being provided with an opening 7 for fixing it in the channel 3.
  • the housing element of FIG. 2 is of the same type as that of FIG. 1, its shape being parallelepipedal instead of being cylindrical and in FIG. 2, the references used are used to designate different elements of FIG. 1 to designate the corresponding elements of Figure 2, but assigned the letter "a".
  • FIGS. 3, 4 and 5 show, in axial section, both the mode of FIG. 1 and that of FIG. 2.
  • the channel 3 has, internally, a locking bar 8 resiliently mounted and terminated by a hook 9 intended to cooperate with the opening 7.
  • the member 4 is intended to be engaged by an introduction opening 11 situated at the rear end 14 of the body 1 and to abut against a shoulder 12 in the vicinity of which a slot 13 is made for the passage of a male tongue (not shown). In this position, the hook 9 cooperates with the edge of the opening adjacent to the shoulder 12 so that the member 4 is blocked.
  • the lateral surface of the body 1 comprises, angularly offset by 180 °, two first teeth 16, these teeth being located in the vicinity of the end provided with the insertion opening 11.
  • On the lateral surface of the body 1 are also provided , a pair of second teeth 17 aligned with the first teeth 16 and offset towards the end provided with the slot 13.
  • the introduction opening 11, on the side of the locking bar 8, has an inclined ramp 19.
  • the cover 2 has a skirt 21 with a bottom 24 pierced with a central hole 25.
  • Each elastic tongue 23 has, at its free end and on its internal face, a hook 26 having an inclined ramp 26 b and a steep 26 c .
  • the bottom 24 and the opening 25 are lined with a plastic material or a gel called "self-healing" 30, that is to say, a material which is flexible and elastic and which allows it to be deformed or perforated and which tends to return to its original shape.
  • the cover 2 is placed in a waiting position, that is to say, a position in which the hooks 26 cooperate with the pair of first teeth 16, then the member 4 is engaged in the opening 25, the material 30 is deformed to allow passage of said member 4, the latter being pushed until it comes into its locked position (see FIG. 4) then, the cover 2 is pushed so that the hooks 26 escape the teeth 16 and come, by their abrupt 26 c , to cooperate with the teeth 17, the cover thus occupying a locking position (see FIG. 5).
  • the material 30 is compressed between the end of the body 1 adjacent to the introduction opening 11, and surrounds the crimping part of the member 4 and the corresponding end of the conductor 5 so that the sealing is achieved.
  • the plate 28 When the cover is pushed from the standby position (fig. 4) to the locking position (fig. 5), the plate 28 cooperates with the ramp 19 and abuts against the end of the side wall of the 'member 4 so that, if the latter was not perfectly positioned, the engagement of the cover towards the locking position ensures that said member 4 is put into correct position.
