Electrical connector comprising a male housing element (1) and a female housing element (2) with a skirt, a U-shaped locking key (60) with two wings (61) and a core (62) and can occupy two positions, a pre-locking position and a locking position in which it blocks electrical contact members in channels, characterized in that in the skirt extend two conduits (51) which, through a slot (53) , open in the skirt, while the wings (61) of the key (60) each have a tab (75) so that, in the locking position of the key (60), the tabs are erased in the conduits (51) whereas on the contrary, when the key (60) is in the pre-locking position, the tabs (75) project into the skirt through the slots.

Description

Electrical connector The present invention relates to a connector

  electric. The present invention relates to electrical connectors of the type comprising a male housing element with a series of channels in which female electrical contact members are housed, said male housing element being intended to be inserted into the skirt of a female housing comprising a series of channels in each of which is housed a

  male electrical contact member terminated by a lan-

  lying in wait in the skirt and intended to cooperate

  with the corresponding female electrical contact member

dant.

  Known key lock systems

  lage intended to block the electrical contact members

  females in the canals and which form, at the

  surface, protrusions so as to oppose the engagement-

  ment of the male element in the female element if the

key is not locked.

  Such connectors offer great security because they allow assembly of the housing elements only if the electrical contact members

  females are perfectly inserted into the canals.

  We also know key systems

  for the electrical contact members

  only males, but these systems do not make it possible to oppose the assembly of the housing elements if they

are not locked.

  One of the aims of the invention is to remedy

dier to this disadvantage.

  The connector according to the invention is of the type comprising a male housing element comprising a series of channels intended to each receive a female electrical contact member, means being provided for locking said female electrical contact members in said channels , a female housing element having a body with a series of channels each intended to receive a male electrical contact member terminated by a tongue, said body being extended by a skirt intended to receive the male housing element and in which the tongues protrude, said body having,

  on the one hand, in each channel, bars of ver-

  rusting movable elastically and having a hook intended to cooperate with a notch in the male electrical contact member, and, on the other hand, a U-shaped locking key with two wings and a

  core, said key comprising on its core spikes tra-

  pouring openings of the body and opening into the channels to cooperate with retaining members of said male electrical contact members, said locking key being able to occupy two positions, a pre-locking position in which the pins are released from the openings to allow setting places male electrical contact members in the channels and a locking position in

  which the pins cooperate with the

  held, said connector being characterized in that the skirt comprises laterally, on two opposite walls and longitudinally, two conduits which, by a slot, open in the skirt, while the wings of the key each comprise a cleat, the cleats being

  made so that in the locked position

  age of the key, the tabs are deleted in the con-

  duits, whereas on the contrary, when the key is in

  pre-locking position, the tabs make sail-

  ties in the skirt through the slits. Thanks to this provision, if the organs

  of male electrical contacts are not suitable-

  ment put in place, the key can not be placed in the locked position and the tabs oppose the assembly of the housing elements. In addition, the key is located in the vicinity of the end of the housing element opposite the skirt and outside of said female housing element so that it is

S15 easily maneuverable.

  Preferably, the tabs have a length such that in the key pre-locking position, the male housing element abutting against said tabs, the male electrical contact members

  and females stay away from each other.

  The invention will now be described.

  The connector shown in the figures

  takes a male housing element 1 and a

female housing 2.

  The male housing element 1 is formed of a body of insulating plastic material having two lateral faces 1a and 1b, a front end

  lc, a posterior end ld and two side walls

rales le and lf.

  The body is divided into a number of channels 5 each intended to receive an organ

  female electrical contact 6 comprising, at one end

  mite, an elastic clamp 4 and, at the other end,

  crimping lugs 3 for an electric conductor

than 14.

  Each channel 5 has an inlet end

  production 7 by which the member 6 is inserted and a stop 8 in the vicinity of the anterior end

  lc for retaining said member, said stopper being per-

  created by an opening 9 for the passage of a tongue

male 42.

  In each channel, a bar is provided.

  elastic locking plate 11 having a cross

  chet 12 intended to cooperate with an opening 13 of

organ 6.

  In the If wall are practiced, trans-

  versally to the body, openings 15 which open into the channels 5 at an intermediate point of their

  length, the female electrical contact member pre-

  feeling a thinned profiled part 16 coming to be located

  to the right of the opening 15 and connected by a shoulder-

  ment 17 to the part coming to bear against the stop 8.

  The lateral faces 1a and 1b include first projections 21 and second projections 22, a key 20 with a U-section with a core 20a and two

  wings 20b being mounted on the body of element 1.

  The lateral faces 1a and 1b each have projecting bars 24 for guiding the edges of the wings 20b, while the core is provided, on its internal face, with a series of pins 26 intended

  fit into the openings 15.

  Each wing 20b, on its internal face in the vicinity of its free edge, comprises a hook 27 intended to cooperate, selectively, with the first

  projections 21 and the second projections 22.

  As seen in Figure 5, the key can thus occupy a pre-locking position

  in which the bars 11 can play elastic-

  ment and the pins 26, spaced from the channels, can

well be set up.

  When the members 6 are housed in the channels 5, the key 20 can be locked by passing the hooks 27 behind the projections 22, the pins 26 then cooperate with the profiled parts

  16, while the core 20a, bearing against the bars-

  elastic rets 11, blocks these.

  The face of the element 1 has a gold-

  gane 30 to ensure the locking of the two housing elements 1 and 2 when they are engaged one in

the other.

  The female housing element 2 has a body 36 with channels 37 intended to receive,

  each, a male electrical contact member 38 pre-

  feeling, at one end, crimping lugs for a conductor 41 and, at the other end, a

  tongue 42 intended to be inserted in the clamp 4.

  Each male electrical contact member

  38 has a perforation 43 and a notch 44.

  The channels 37 have an introduction opening 45 through which the members 38 are inserted and an end of reduced section 46 to limit the engagement of said members 38 in said channels 37, the body 36 being extended by a skirt 35 in

  which extend the tabs 42. The skirt 35 af-

  make a parallelepiped shape with four walls

side 35a, 35b and 35c.

  The skirt 35 is shaped so as to pre-

  feel two conduits 52 opening, on the one hand, on the bottom and, on the other hand, on the free edge of said skirt, each conduit, along the inner face of the walls 35a and 35b, having a slot 53 .

  The wall 35c has a light 55 des-

  intended to receive the member 30 of the element 1.

  The body 36, on its lateral walls cor-

  corresponding to the side walls 35a and 35b of the skirt

  , has two guide bars 56, the cor-

  corresponding to the skirt forms a shoulder 57.

  Between the shoulders 57 and the bars 56 are guided the wings 61 of a U-shaped key 60 whose core 62, along the edge facing the insertion openings of the male electrical contact members 38, is provided with '' a series of pins 64 intended to pass through openings 65 of the body

  36, openings opening into the conduits 37.

  The edge of the wings 61 is terminated by hooks 67 intended to cooperate, selectively, with first projections 68 and second projections 69 so that the key 60 can occupy a position of

  pre-locking to allow the introduction of the

  ganes 38 in the channels 37 and a locking position

  lage to block said organs in said channels.

  In each channel 37 is shaped an elastic locking bar 70 having a

  hook 71 intended to cooperate with the notch 44.

  The wings 61 of the key 60, on the tour side-

  born towards skirt 35, are each extended by a

cleat 75.

  The catches 75 are made so, in the key pre-locking position, to protrude into the skirt 35 through the slots 53, while in the locking position, said catches fully insert into the conduits 51. The Figures 14 and 15 show that, when the key 20 occupies the locking position, the

  housing elements 1 and 2 can be assembled.

  In this position, the female electrical contact members 6 are inserted in the channels 5 so that the hooks 12 cooperate with the openings 13, the pins 26 cooperating with the profiled parts 16 and

  the key 60 also being in the locked position.

  FIG. 16 shows on the contrary, when the key 20 is not locked and the key 60 being locked, that the male element 1 cannot be engaged in the skirt 35, the core of said key abutting against

  the free edge of the wall 35d of said skirt.

  If the key 20 is locked, but the key is in the pre-locking position (see FIG. 17), the tabs 75 projecting from the skirt 35, the wall lc of the male housing element 1 abuts against said tabs 75 and the two housing elements

cannot be coupled.

  Preferably, the tabs have a length such that if they protrude into the skirt 35, the electrical contact members of the two housing elements cannot touch each other, if an attempt is made to engage

  the male element 1 in said skirt 35.

  Of course, the invention is not limited

  to the embodiment which has just been described and re-

  present. Many modifications can be made

  details without going beyond the framework of the in-

vention.
