Description

Electrical connector housing element The present invention is

relates to an item

  of electrical connector housing.

  The invention relates to a housing element capable of cooperating with a complementary element as well as a

  case intended to be housed in a housing element.

  The invention relates, more particularly, to housing elements having a body of generally parallelepipedal shape having a series of channels intended to each receive a male or female electrical contact member having, at an intermediate point of their length, a portion thinned and a locking key

  to block said organs in the channels.

  Such housing elements which are made of molded plastic require the production of

very complex and expensive molds.

  A first object of the invention is to simplify

such manufacture.

  The housing element, object of the invention,

  is of the type comprising a body of generally parallel shape

  Lepipedic with a series of channels intended to receive

  see, each, an electrical contact member having,

  at an intermediate point of its length, an amin-

  cie and a locking key to block the electrical contact members in the channels, said members

  of electrical contacts being intended to receive or-

  complementary ganes engaged by one end of the body, said housing element being characterized in that the

  locking key consists of a U-shaped element

  feeling two wings and a soul, the first wing fitting into a slit of the body transverse to the channels, while

  that the second wing is guided at the end of the body of the

  tine to receive the complementary organs of the electrical contact organs, the first wing having holes corresponding to the channels and having a part having dimensions such that they can be crossed by organs and a lateral notch corresponding to

  thinned parts of said electric contact members

  ques, while the second wing presents a series of

  vertices intended to coincide with the channels for the step-

  wise additional organs, means being provided

  to lock the key in a first pre-lock position

  beam in which the parts of the holes, the dimensions of which correspond to those of the members coincide with the channels and the openings of the second wing are offset with respect to said channels and a second locking position in which the thinned parts of the electrical contact members are inserted in the notches and in which

  the openings are located to the right of the canals.

  Thanks to this arrangement, an ele-

  housing that is simple to make and in which the

  nes complementary to the electrical contact members housed in the channels cannot be inserted, even

  partially if the key is not completely locked.

  Preferably, the body includes a housing intended to receive the soul of the locking key when

  it occupies the locking position. Thus, the elec-

  housing cannot be inserted into a complete element

  if the key is not completely erased.

  According to a constructive detail, the body comprises-

  te two lights offset transversely on the body, while the locking key has a projection housed in one of the lights in the pre-locking position

  and the other in the locked position.

  Finally, according to a last characteristic,

  the locking key has a lug offset longitudinally

  nally on the key to be located closer to the core than the projection, said lug having, on the side of the projection, a ramp and, on the opposite side, a steep, said lug coming to be housed in the light corresponding to the position of

pre-locking of the projection.

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

  particular given by way of example only and representing

  tee to the accompanying drawings, in which: Figure 1 is a perspective view of an element

  electrical connector housing according to the invention.

  Figure 2 is a perspective view of the element

  the housing of FIG. 1, the locking key being

supposedly withdrawn.

  Figure 3 is a front elevation view of

  the housing member, the key being in the pre-

  locked. Figure 4 is a sectional view along the line

4-4 of figure 3.

  Figure 5 is a sectional view along the line -5 of Figure 4. Figure 6 is a sectional view along the line

6-6 in Figure 3.

  Figures 7 and 8 are views on a larger scale.

  showing it the key respectively in the pre-

  locked and in the locked position.

  Figure 9 shows in elevation a connecting member

  electrical connection for use with the element

housing, according to the invention.

  The housing element shown in the figures comprises a body 1 of generally parallelepiped shape with two long sides 2 and 3 and two short sides 4 and 5.

  On the side of one end 1a, the body 1 presents

  te a series of channels 7, while on the other side

  end 1b, said body is terminated by a skirt 8.

  Each channel 7 is intended to contain an organ-

  no electrical connection 10 such as that shown in FIG. 9, this member has, at one end, a female part 11 with a clamp 12 intended to grip

  an organ: male and, at the other end, service legs

  weaving 13 intended to enclose a stripped end of a conductor and crimping tabs 14 intended to be

crimped on said conductor.

  Between the legs 13 and the part 11, the body 10 has a thinned part 15. The housing element, on the side of its end

  opposite the skirt 8, present on the internal face of the pa-

  kings 2 and 3 of grooves 17, while in part

  body 1, across channels 7, is pra-

ticked a slit 18.

  In the side wall 4, in the vicinity of the former

  end, there is a housing 20 and in the bottom of the housing, near the wall 2, extends a slot 19 which opens into two slots 22 and 23 formed in

wall 2.

  A locking key 25 is provided and has a U shape to present a core 26 and two wings 27

and 28.

  The wing 27 is intended to be inserted in the slot 18 and has a series of holes 30 intended to coincide,

  each with a channel 7, each hole 30 having a par-

  tie 30a having a shape and a dimension corresponding to

  those of the female part 11, organs 10 and a

  check mark 30b having a dimension corresponding to that of the

  thinned part 15, said notches being angularly offset

  in such a way, when the key is engaged, that first the parts 30a are located opposite the channels 7 and that at the end of insertion, the parts 30b coincide with said

channels 7.

  Wing 28, along each of its long edges

  longitudinal, has a longitudinal projection 31 intended

  to cooperate with the corresponding groove 17, openings

  res 33 being formed in said wing 28 and being intended

  born in correspondence with channels 7.

  Each opening 33 has a section corresponding to that of a male member intended to engage in the part 11 of the female members 10, and is flared from the side

external of said wing 28.

  In the vicinity of the core 26, one of the edges of the wings 27 and 28 is connected by a cheek 34 having a

  projection 35 and a lug 36 with an inclined ramp 36a ter-

undermined by a steep 36h.

  The key 25 is engaged in the body 1 so that the projection 35 and the lug 36 are housed in the slot 22. In this position, the key can no longer be removed since the abrupt 36b bears against the edge of the light 22. As seen in Figures 4, 5 and 7, this

  first position corresponds to a pre-lock in the-

  which parts 30a of the holes 30 coincide with the ca-

7.

  In this first position, the openings

  33 are offset from the channels 7.

  The members 10 are placed in the channels 7 so as to abut against the wing 28 (see FIG. 4),

  then key 25 is pushed to the locked position

  ge (see figure 8) so that the projection 35 is inserted

in the light 23.

  In this position, the thinned parts 15 of the members 10 are housed in the notches 30b, while

  that the openings 33 coincide with the channels 7.

  Note that in the locked position,

  the core 25 is inserted into the housing 20 so that the element

  bootmaker can be engaged in a complementary element

  be silent or in a support. If the key is not locked, the core 26 remains protruding so that the housing member

cannot be set up.

  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.
