Abstract

The present invention relates to a quick-connect multiple electrical connector comprising a female element 1 which can be engaged in a hole 5 of a thin wall 3 and provided with means for fixing to this thin wall, a male element 2 provided with a collar 7. and a ring 8 provided with fixing means suitable for placing the flange 7 in abutment on the end face of the female element 1. According to the invention, the female element 1 and the ring 8 are provided with lugs of fixing by engagement and pivoting 4 or 4 'and 9 or 9'.

Description

The invention relates to a multiple electrical connector with connection

  fast, the kind of those used to connect two bundles of electrical wires of both

side of a thin wall.

  The connectors of the type defined above generally comprise a female element fixed to the wall by a nut itself screwed to an external thread, and a male element adapted to engage in the female element.

  through a hole in the wall and provided with a

  it bears against the female element by an ûiletée ring, itself screwed on the same thread as the nut. The assembly of such a system requires a first

  screwing operation with holding the female element

2 -

  during the engagement of the nut and a second

  tightening ration after engagement of the male element.

  But screwing operations are difficult to automate.

  using robots, especially if the robot needs to

  come on two independent parts to maintain it. The connector which is the subject of the invention is

  without screwing or holding operation.

  This connector is characterized in that the female element

  and the ring are provided with fixing lugs by engagement-

ment and pivoting.

  The lugs of the female element may be shaped so as to grip the edge of the hole of

  the thin wall. The lugs of the ring can be

  formed so that they can also hold onto the

  edge of the thin wall hole, or on the

  of the pins of the female element.

  Two embodiments of the electrical connector according to the invention will now be described by way of nonlimiting example, with reference to the appended drawings in which: FIG. 1 is a perspective view of a first

  embodiment, the various elements of the connection

  being represented separately; Figure 2 is an elevational view showing

  the female element fixed on the thin wall; Figure 3 is an elevational view of the connector in place; Figure 4 is a side view; Figure 5 is a section along V-V 'of Figure 4; Figure 6 is an elevational view of a second

  embodiment, the various elements of the connection

  being represented separately; Figure 7 is an elevational view showing the hole in the thin wall; Figure 8 is a perspective view showing a pair of lugs of the female member and the ring;

  Figure 9 is a side view of the fitting.

  As shown in Figures 1 to 5, the connection

  according to the invention comprises a female element 1 and

  a male element 2 which must be connected to each other

  being on both sides of a wall

thin 3.

  Element 1 has the shape of a cylindrical sleeve

  which has on its periphery three lugs 4 outer-

  4 cylinders and arranged at 120 each other, each of these lugs having a slot 4a arranged

  in a plane perpendicular to the axis of the sleeve. The

  king 3 has a hole 5 whose edge has a symmetry of 120 and has a series of first portions 6a which extend over an angle at most equal to 30 and whose radius is equal to the outer radius of the sleeve 1, a

  series of second portions 6b which extend over one year

  not more than 30 and whose radius is equal to

  outer radius of the lugs 4, and a series of thirds

  my portions 6c that extend at an angle at most

  equal to 60 and whose radius is greater than the two

  cédents. The sleeve 1 can thus be engaged in the hole 5 of the wall 3 and fixed thereto by pivoting it so that the shoulders 6d, which connect the portions 6a and 6b, engage with the slots 4a.

pins 4.

  The male element 2 is cylindrical and has an outer diameter

  substantially equal to the inside diameter of the

  female 1; it comprises a flange 7 whose outer diameter is substantially equal to the outer diameter of this female element. It can thus be engaged in the female element, its collar 7 coming

  in abutment against the edge of this female element.

  The male element 2 is held in place by a

-

  8. This ring has a sensitive inner diameter

  equal to the outer diameter of the male element 2 and

  can be pushed onto this element. It includes

  end three protruding lugs 9 arranged at 120 from each other. Each of these lugs is square with, in its portion adjacent to the edge of the ring, a recess 9a of width equal to the thickness of the sheet and disposed in a plane perpendicular to the axis of the ring; it has the shape of a cylindrical sector whose outer radius is equal to that of the portions 6c of the edge of the opening 5 and whose

  the inner radius is equal to that of the portions 6b.

  The ring 8 can thus be fixed to the wall 3, keeping the male element 2 in the element. female 1,

  by inserting the lugs 9 in the hole 5 and making

  rotate the ring so that the shoulders 6e,

  linking Dortions 6d and 6c, engage in

9a hooks.

  The embodiment of Figures 6 to 9 is broadly similar to that just described, but differs in form and arrangement of the lugs.

  The opening 5 'of the sheet 3 has a first

  notch 6'a which extend over an angle at most equal to 60 and which are separated from each other 6 - by notches 6'b extending over an angle at most equal to 60. The radius of the parts 6'a is equal to the outer radius of the sleeve 1 and that of the portions 6'b is equal to the outer radius of the lugs 4 'of this sleeve 1, these lugs being provided with a slot 4'a. The sleeve 1 can thus be fixed to the sheet 3 as in the method of

  previous realization. In addition, the lugs 4 '

  carry on the opposite side to the slot an extension 4'b; the width of the recesses 9'a of the lugs 9 is equal

  the sum of the thicknesses of sheet 3 and these

  4b. The ring 8 can thus be fixed by engaging its lugs 9 'behind the extensions

4'b pins 4 '.

  It goes without saying that the present invention should not be considered as limited to the two embodiments described and shown, but covers, on the contrary,

all variants.
