The key 31 can occupy a pre-locking position in which flaps 45 protrude and a locking position in which the flaps 45 are elastically erased in the housings (47) of said key. The flaps 45, in the pre-locking position, oppose the assembly of the housing element (1) with a complementary element.

Description

Electrical connector.

  The present invention relates to a connection

electric tor.

  The present invention relates to electrical connectors

  triques consisting of a first housing element comprising

  so many, a series of channels, in each of which is inserted

  a female electrical contact member and a second element

  ment of the complementary housing of the first and having a series of channels corresponding to those of the first and, into each of which is inserted a male electrical contact member, the male members being inserted into the members

  females when assembling the two housing elements.

  In some connectors, the female electrical contact members are retained in the channels by

  locking members formed by elastic tabs

  ticks provided with pins intended to be inserted in notches

female organs.

  In such a way that the housing elements cannot

  feels to be assembled only if the female organs are suitable

  securely installed in the channels, a locking key is provided which can only be inserted into the corresponding boot element if the position of the tabs

  elastic corresponds to the locking of the female organs.

  One of the aims of the present invention is to provide an electrical connector of the above type which opposes the coupling of the two housing elements, if the female members are not properly locked

in the canals.

  The invention relates to an electrical connector of the type having a first housing element and a second element complementary to the first housing element, said first housing element having a series of channels.

  in each of which is inserted an electrical contact member

  female stick, said complementary housing element comprising a series of channels intended to each receive a male electrical contact member having a contact part intended to be inserted in a contact member

  corresponding female of the first housing element, each

  that female contact member having a body provided with notches and means for fixing an electrical conductor, each channel comprising, at least, one member

  locking formed by an elastic tab present

  so much, at least one lug intended to be inserted in the notch

  of the female electrical contact member, between the organ-

  the locking nes being provided with slots intended to receive advances from a locking key, means being provided for maintaining the locking key in at least two positions, a pre-locked position in which the projections are spaced from the slots so that the locking members can play freely to

  allow the installation of electrical contact members

  that females and a locked position in which the projections are inserted into the slots to block said locking members, said connector being characterized in that the first housing element is arranged so as to receive the locking key, on the side of its end , intended to cooperate with the complementary housing element, said locking key having a wall provided with a series of slots intended to be aligned with the channels of the housing elements and to allow the passage of the male members, and, laterally, at least one component

  elastic protruding from the surface of the key and suscep-

  tible to be elastically erased in a housing thereof, said flap being mounted so that in the

  pre-locking position, it is located protruding from the

  end of the first housing element intended to cooperate

  with the complementary element and thus opposes the assembly

  blocking of said two housing elements, while in the locked position, it is elastically erased in

housing.

  Thanks to such an arrangement, it is impossible

  ble to assemble the two housing elements, if the female members are not perfectly in place and if the

  locking key is not in the locked position.

  According to a constructive characteristic, the locking key comprises two stirrups which extend from the wall pierced with slots for the passage of the male members, on the side opposite to the face of said wall intended to be turned opposite the element of housing

  complementary, each stirrup having a free side of the

  keen to cooperate with the first internal projections of the

  first housing element in the pre-lock position

  lage and with second protrusions in the position of

  rusting, the flaps being shaped in parts of

  the key connecting the stirrups to said wall.

  Finally, the free ends of the flaps comprise

  tent a notch, while the inner wall of the complementary housing member has internally stops against which abut said notches in the

  pre-locked position of said flaps.

  The invention will now be described in more detail with reference to an embodiment.

  FIG. 8 is a sectional view of the connector,

  In Figure 1, an element of

  housing 1 intended to receive electrical connection members

female triques 2.

  This housing element 1 is intended to cooperate with a complementary housing element 3 (see figures

  7 and 8) which has a series of channels 4 in each of the

  which is housed a male electrical connection member 5.

  The housing element 1 (see Figures 5 and 6)

  has a series of channels 8 each intended to receive

see an organ 2.

  Each member 2 has, at one end, a

  elastic clamp 9 intended to grip a corresponding male organ

  laying and, at the other end, crimping lugs 10

of an electrical conductor 11.

  Each member 2 has notches 13, while

  that in each channel there are two locking members

  lage S15 constituted by elastic tongues having,

  each, a lug 16 intended to cooperate with a corresponding notch

  laying to ensure the locking of said member 2. Behind each locking member 15 is

formed a slot 17.

  The housing element 1 has a rear end 22 through which the members 2 are inserted in the channels 8 and a front end 23 intended to cooperate

with complementary element 3.

  Housing element 1, on each of two sides

  opposite, is provided with a locking bar 20 termi-

  born by a lug 21 having a ramp 21a turned to the side of the front end 23 and terminated by a steep 21b

turned to the opposite side.

  The complementary housing element 3 has two grooves 24 having projections 25 intended to cooperate with the lugs 21 to ensure locking

  of the two housing elements when assembled.

  In the grooves 24 are provided, in the vicinity of the former

  end of the complementary housing element 3 intended

  to receive the housing element 1, stops 27.

  Internally element 1 comprises, out of two

  opposite sides, projections 28 and 30.

  The projections 28 have, on each side, ramps 28a, while the projections 30, on the end side 23, have a ramp 30a and, on the side of

the end 22, a steep 30b.

  On the end 23 end, the box element

  tier 1 is intended to receive a locking key

  generally referenced by reference 31.

  The locking key 31 has a front face 32 provided with a series of slots 33 intended to be aligned with the channels 8 and to be traversed by

  the male organs 5. The internal face of the wall 32 constitutes

  kills a stop to oppose forward movement

organs.

  The wall 32 has, on its internal face, projections 35 intended, when the key is in place, to be inserted into the slots 17 in order to block the members

lock 15.

  The internal face of the wall 32, in the vicinity of two opposite edges 32a, includes stirrups 40 of which

  the free side 40a is cut to form, on its inner edge

  dull as well as on its outer edge, ramps 40b.

  The locking key 31 is intended for occu-

  per a pre-locking position (see FIGS. 3 and 5) in which the projections 35 are distant from the slots 17, the free sides 40a being inserted between the projections

28 and 30.

  On each side 32a is articulated a flap 45.

  Each flap 45 is produced so as to project from the surface of the side 32a and to be able to be pivoted against the action of an elastic part 46, so as to be erased in

a housing 47 on the sides 32a.

  Each flap 45, on its free edge, has

a notch 49.

  As seen in Figures 5 and 7 in the pre-locking position of the key 31, the flaps 45 are open and the projections 35 are spaced from the slots 17. If we want to place the key 31 in the locking position, push this in the element

  1 so that the free sides 40a of the stirrups are crossed

  feels the projections 28. If the members 15 are properly in place, that is to say, if the pins 16 are engaged in the notches 13, the slots 17 allow the engagement of

  35 and flaps 45, cooperating with the

  internal mites 23 of element 1, are tilted elastic-

  in their housing (see Figure 6).

  If on the contrary (see FIG. 7) one of the electrical contact members 2 is not suitably inserted in its channel 8, the members 15 mask the slots 17 so that the projections 35 cannot be inserted in the latter, the flaps 45 remain deployed and stops 27, provided in the grooves 24 of the complementary housing element 3, come to meet the notches 49 so that said complementary element cannot be put

in place.

  Thus the locking key 31 constitutes double security. Indeed, it opposes, on the one hand, the assembly of the two housing elements if the connector is not suitably equipped and, on the other hand, it can only be placed in the locking position if the electrical connection devices are suitably placed

in place.

  Of course, the invention is not limited

  to the embodiment which has just been described and represented

  smelled. We can make many modifications

  detail without departing from the scope of the invention.
