Description

Electrical connector The present invention relates to a connector

electric.

  The invention relates to a compressed electrical connector.

  nant a female housing element comprising two rows of channels intended to receive, each, an electrical contact member and a male housing element intended to be inserted in the female housing element and provided with a series of channels corresponding to those of said female housing element and intended to each receive an electrical contact member complementary to those of the channels of the female housing element. The electrical contact members are

  integral with conductors inserted on electrical circuits

ques.

  Generally the channels have interior-

  elastic locking tabs having lugs intended to be inserted into the notches or openings of the electrical contact members to block them in

said channels.

  It has been found that if traction is carried out on the conductors, the pins escape from the notches or openings of the electrical contact members. It has been imagined, to remedy this drawback, to provide keys for

  lock which can occupy two positions, one posi-

  waiting position in which the locking tabs can play freely to allow the establishment of the electrical contact members in the channels and a locking position in which they block the

locking tabs.

  This solution presents a number of

conveniences.

  The keys are generally inserted perpendicularly.

  rement to the longitudinal axis of the housing, so that

  may consider making waterproof connectors.

  s As the connectors are generally very small and the locking tabs are also very small, they are fragile and risk

  break if a pull is made on the conduc-

  teurs, despite the locking key.

  One of the aims of the present invention is to

  remedy these various drawbacks.

  The connector according to the invention is of the type comprising a female housing element with two rows of channels intended to each receive an electrical contact member set at one end with an electrical conductor and means for locking the electrical contact members in the channels, said female housing element being extended by a skirt intended to receive a male housing element provided with two rows of corresponding channels

  to those of the female housing element and intended to receive

  see, each, an electrical contact member complementary to those of the channels of the female housing element and set, at one end, with an electrical conductor, each channel of the male housing element comprising locking tabs with lugs, electrical contact members and a key capable of occupying a first waiting position in which the legs can play freely for the establishment of the electrical contact members and a locking position in which said locking legs are blocked , the pins being inserted into openings of the electrical contact members, said connector being characterized in that the channels of the first row each have a light opening on a lateral face, the channels of the second row each having , a light opening on a side face opposite to that on which the channels of the first row open, the key to locking consisting of a sleeve mounted on the male housing element on the side of its end intended to be inserted in the female housing element and comprising two flaps intended to hide the lights in the locking position, each flap comprising, on its internal face, pins intended to be inserted in said lights and to cooperate

  with the openings of said electrical contact members.

  Thanks to this arrangement, the means of ver-

  rusting of the electrical contact members is reinforced and a seal can be placed on the male housing element, this seal fitting into the skirt of the element

  female housing and being held by the locking key

age.

  In addition, the key prevents the assembly of the elements.

  housing elements if the contact members are not

suitably wedged.

  According to a constructive characteristic, the locking tabs of each channel are located in said channels on the side opposite to the lights and between the tab

  for locking a channel in a row and the lug

  rusting of a channel, corresponding to the other row, is

  provided a slot, while the locking key comprises

  te, arranged between the two shutters, a series of bars

  intended to be inserted in said slots.

  According to another constructive characteristic, the locking key has, laterally on two opposite sides, two notches delimiting between them locking bars having, on their internal face, lugs, while the corresponding walls of the male housing element are provided with notches corresponding to the positions

  waiting and locking the key.

  According to a particular embodiment of

  the invention, the locking means of the control members

  electrical tact in the channels of the female housing member include locking tabs disposed

  opposite by two in each channel and presenting er-

  gots intended to cooperate with openings of the corresponding electrical contact members, free spaces being provided between the locking tabs and the internal side wall of said female housing element and slots being provided between the locking tabs of

  each channel of a row and those of the corresponding channels

  dants in the other row, a locking key being pre-

  view and being formed of a sleeve having three series of bars, two extreme series intended to be inserted in the free spaces and an intermediate series intended

to be housed in the slots.

  Finally, according to a last characteristic,

  the bars of the intermediate series of the key of the

  The female housing are cut from a partition which, on the side opposite to the said bars, ends in an inverted V-shaped part, while the series of the bars of the key of the male housing element are intended to be inserted in the slots separating the locking tabs of said male housing element and integral with a cross-member abutting, when the male and female elements are assembled, against the part

in inverted V.

  Thanks to this arrangement, the key of the male housing element blocks the key of the female housing element

in this last.

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

  in the channels of the male housing member.

  Figures 7, 8 and 9 are cross-sectional views

  trant the various blockages opposing the assembly of the housing elements when the keys and the organs

  are not properly set up.

  The connector shown in the figures comprises a female housing element 1 and a housing element

male 2.

  The female housing element 1 comprises two rows of channels 4 each intended to contain a male electrical contact member 5 comprising a body 6 with,

  at one end, tabs 7 for crimping a container

  conductor 8 and, at the other end, a flat tongue 9. In each channel 4 extend two tabs

  locking 10 and 11 facing each other and whose fac-

  these tours opposite each other include er-

  gots 13 intended to cooperate with openings 14 in the body

6.

  The legs 11 are separated by a slot 16, while a free space 18 is provided between the legs

  and the internal side wall of the female element 1.

  The female element 1 is extended, on the opposite side

  dried at its end 1b through which the organs are introduced

  nes 5, by a skirt in which the element is inserted

male 2.

  A first key for locking the contact members 5 is provided. This key 20 (see FIG. 5) is constituted by a sleeve 21 having two side walls 22 whose free edges are connected by two

parallel walls 23 and 24.

  In the wall 23 are cut bars and in the wall 24 of the bars 26, each bar,

  at its free end, having a shoulder 27.

  The wall 23, along the edge opposite to that in which the bars are cut, is provided, on

  its internal face, bosses 28 for guiding the lans

  lookouts 9. The end of the wall 24 has bosses

corresponding ages 29.

  Key 20 has an intermediate partition

  parallel to walls 23 and 24 and in which are

  cut from the bars 31 comprising, at their free end,

  a protuberance 32 providing two shoulders 33, the partition

  S its intermediate 30, on the side opposite to that in which the bars 31 are cut, ending in a part

with inverted V section 35.

  When the organs 5 are put in place, the pat-

  your 10 and 11 can play freely so as to spread

  elastically until the pins 13 are inserted

in the openings 14.

  When the members 5 are correctly positioned, S15, the key 20 can be put in place, including the bars 25 and

  26 block the legs 10, while the bars 31 block

  the legs 11 (see Figures 1 and 9).

  It is understood that if the organs 5 are not

  properly installed, the free ends of the pat-

  your 10 abut against the shoulders 27 and the free ends of the legs 11 against the shoulders 33 so that it is impossible to insert the key 20, the latter remaining in the skirt 1a, the male element 2 cannot be mounted (see

Figures 7 and 8).

  In Figure 6, there is shown in perspective a female electrical contact member formed of a body 41 with, at one end, crimping lugs 42 for fixing a conductor and, at the other end, a clamp elastic 43 intended to enclose a male tongue

  9. The body 41, on two opposite walls, presents or

  vertices 44 to allow the engagement of the ver-

  rusting as will be explained later.

  Male element 2 has two rows of ca-

  channels 46 corresponding to channels 4 and intended, each,

  to receive a member 40 introduced by one end 2b of-

so-called channels.

  In each channel 46 extends a glass tab.

  rusting 47 provided with a lug 50 intended to cooperate with

  an opening 44 of the members 40, a slot 48 being formed

  between the corresponding legs 47 so that they

they can play freely.

  In each channel 46, on the side opposite the pat-

  te 47, a light 49 is provided.

  The male housing element 2 is intended to receive

  see a second locking key 52 of the members 40, this key S2 (see FIG. 4) takes the form of a sleeve with two side walls S4 which, at one end, are connected by parallel crosspieces 56, 57 and, at the other end, by a crosspiece 58. From the crosspiece

  56 extends an elastic flap 59 and, from the crossing

  an elastic flap 60 extends 57. From the cross member

  58 extend a series of parallel bars 61.

  The flap 59, on its face turned opposite the

  flap 60, comprises a series of pins 62, the flap 60 pre-

  feeling corresponding lugs 64. The bars 61, at their free end, are terminated by a protuberance

  65 determining two shoulders 66.

  Between the bars 61 extend bars 67 which are inserted into the slots 68 of the housing element 2 and which thus form dividing partitions

  the corresponding ends of the channels 46.

  The walls 54 each have two notches

  the 70 which delimit locking bars 71 comprises

  both, on the side of the internal face, a lug 72, while in the corresponding side walls of element 2

two notches 74 and 75 are provided.

  When the pins are housed in the notch 74,

  the key occupies a waiting position in which the

  gots 62 and 64 are distant from the channels 46 and the bars.

  61 are released from the slots 48. Thus, the members 40 can

  can easily be introduced into the channels 46 until they abut against the end 2a, the pins being inserted into the corresponding openings 44 of the

organs 40.

  When the members 40 are properly placed, the second key 52 is pushed so that the pins 72 escape from the notches 74 and are received in the notches 75 in order to occupy the locking position. In this position, the pins 62 and 64 are inserted into the openings 44 of the members 40 opposite to those cooperating with the pins 50 and the bars 61 are inserted in

  the slots 48 so that the legs 47 are thus blocked

1

  quées. The housing element 2 is provided, on one side, with an elastic stirrup 80 intended to cooperate with a boss 81 of the housing element 1 to ensure locking

  of the two elements on top of each other.

  It will be noted (see FIGS. 1 and 9) that, if the members 40 are not properly inserted into the channels 46, it is impossible to pass the second key from the standby position to the locked position and

  of course the male housing element 2 cannot be introduced

duit in the skirt there.

  As the pins 62 and 64 are respectively integral with the flaps 59 and 60, they form means of

  locking of the organs 40 which are much more resistant

  as much as the simple legs generally provided and thus hold much better when a traction is carried out

on the conductors.

  It will be noted that the crosspiece 58, when the two housing elements are assembled, abuts against the

  part 35 which can no longer move.

  Given that the keys are housed inside

  of the housing elements, a connection can be made

  watertight, an elastic seal 83 being mounted on the element

  ment 2 and coming to stay in a flared part of the ju-

pe la.

  The rear ends of the members 5 and 40 can be housed in elastic sleeves 84 forming a seal

in the corresponding channels.

  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.
