Definitions

  • the invention relates to electrical connection boxes.
  • the invention relates to electrical connection boxes comprising a male box element comprising a series of channels intended to each receive a male or female electrical connection member and intended to be inserted into the skirt of a female box element having a series of channels intended to each receive an electrical connection member complementary to those of the male housing element.
  • Such housing elements are very well known and widely used in many fields, automobile industries, aviation, etc.
  • the male housing element comprises locking means constituted by an elastic bar, provided with a projection with two inclined ramps connected by an edge, while the skirt has a protuberance intended to cooperate with the projection so that at the start of insertion a relatively large effort so that the protuberance crosses the first ramp by means of an elastic deformation of the elastic strip, while when the edge is crossed the protuberance and the second ramp tend to facilitate the engagement of the male element in the skirt of the 'female element until the two elements are locked relative to each other.
  • One of the aims of the present invention is to remedy these drawbacks.
  • the invention relates to electrical connection boxes of the type comprising a male box element, a female box element with a skirt intended to receive the male box element, each box element being provided with a series of channels, the channels of one of the housing elements being intended to receive male electrical connection members and the channels of the other housing element of complementary female electrical connection members, the male housing element comprising a locking member formed by a resilient bar, one end of which is turned towards the side of the part of the element of said male casing intended to be inserted into the skirt, is integral with said male casing element, while the other end is terminated by a gripping member, said elastic bar comprising means combined with means provided on the skirt in order to ensure the locking of the elements s of housing when they are inserted one inside the other, said skirt being provided with a protuberance intended to cooperate with a projection connected to the elastic bar and having two inclined ramps connected by an edge and arranged so that when the male housing element is insufficiently engaged in the skirt the combined action of the first ramp of the protuberance and of the elastic bar tends to
  • the repelling action of the male housing element is reinforced when its engagement in the skirt of the female housing is insufficient and the uncoupling does not require any additional effort.
  • the opposing device is molded in one piece with the male housing element.
  • the opposing device consists of an independent element and the corresponding housing element comprises means for fixing it.
  • the opposing device is carried by the male box element, the boss being carried by the internal surface of the skirt.
  • the opposing device can be carried by the female housing element and the boss by the male housing element.
  • the boss has two ramps intended to cooperate, one with the free end of a finger and the other with the free end of the other finger and terminated by the stops.
  • FIGS 1 to 9 there is shown an electrical connection box comprising a male box element 1 and a female box element 2 provided on its front face with a skirt 3 intended to receive the male element 1 and a series channels 4 in which are housed male electrical connection members 5 connected to conductors 6 and protruding into the skirt 3.
  • the male box element 1 has a series of channels 8 each intended to receive a female electrical connection member 9 connected to a conductor 10.
  • the element 1 comprises a locking means 11 comprising two elastic bars 12 secured by one end of the front end of the element 1 and the other end of which is connected by a gripping member.
  • the faces of the elastic bars 12 which face each other are integral, each with a projection 14, each projection having a ramp 14a, an edge 14b and a ramp 14c.
  • the upper faces of the elastic bars 12 comprise lugs 15 intended to cooperate with holes 16 on one side 3a of the skirt 3 in order to ensure the blocking of the two housing elements 1 and 2 when they are engaged one in the other.
  • the side 3a of the skirt 3 has a protuberance 20 which has, on the side of the opening of the skirt 3, a flat face 20a extended by two faces 20b which meet on the side of the channels 4, said protuberance thus affecting the shape of a corner.
  • the width of the face 20a is such that when the element 1 is engaged in the skirt 3 the protuberance 20 can be inserted between the bars 12 but, that, when it meets the projections 14, said bars 12 must bend until that the edges, 14b are crossed by said protuberance 20, after which the bars 12 return to their initial position and thus tend through the ramps 14c to promote the engagement of the housing element 1 in the skirt 3. Simultaneously by a downward bending of the bars 12 the pins 15 penetrate the holes 16, said bars 12 returning to their initial position. Thus the housing elements 1 and 2 are locked.
  • the action of the projections 14 may be insufficient.
  • it is provided on each of the two short sides 26 of the housing element 1 an opposing device 25.
  • Each opposing device 25 comprises a plate 28 which is inserted in slides 27 on the short sides 26, said slides having stops 29 and the short sides being provided with pins 30 intended to engage in openings 31 of the plates 28 to ensure locking them.
  • the plates 28 have two ribs 32 and 33.
  • the rib 32 has a free extension 32a terminated by a curved finger 32b, while the tongue 33 is formed by a free extension 33a terminated by a curved finger 33b extending in the direction of the free end of finger 32b.
  • the short internal sides of the skirt 3 are each provided with a boss 40 having, towards the opening of the skirt, a part which tapers with two ramps 40a and 40b, two stops 40c and 40d and a rounded part 40e turned towards channels 4.
  • FIG. 2 shows the position of the fingers 32b, 33b relative to the bosses 40, at the start of the introduction of the male housing element 1 into the skirt 3,
  • Figure 3 showing the corresponding position of the protrusion 20 between the elastic bars 12.
  • Figures 4 and 5, 6 and 7 and 8 and 9 are corresponding.
  • the protuberance 20 bears against the ramps 14a of the projections 14, while the fingers 32b and 33b are first slightly separated from one 'other by the ramps 40a and 40b then come to bear against the stops 40c and 40d.
  • the fingers 32b and 33b are braced by bending elastically, while the boss 20 arrives in the vicinity of the edges 14b. If the insertion of the element 1 in the skirt 3 is stopped, by the combined action of the ramps 14a, the elasticity of the bars 12 and of the fingers 32b and 33b the male housing element 1 is pushed back.
  • the fingers 32b and 33b offer little resistance since they can easily pass through the bosses 40.
  • the housing comprises a male housing element and a female housing element 46 with a skirt 47.
  • the element 45 comprises channels 49 intended to receive electrical contact members such as member 9 (see figure 1), while the element 46 is provided with channels 48 intended to receive the electrical contact members such as the member 5 (see FIG. 1).
  • the element 45 is provided with a locking member 50 having an elastic bar 53 terminated by a gripping member 54, the bar being provided on its two lateral faces with projections 51 each having an inclined ramp 51a, an edge 51b and a second ramp 51c.
  • the locking member includes notches 55 intended to cooperate with protuberances 61 carried by lugs 60 integral with the skirt 47.
  • the ramps 51a are extended by elastic tongues 59.
  • the protrusions 61 abut against the elastic tongues 59 then cooperate with the ramps 51a to elastically bend the bar 53. If the element 45 is insufficiently pressed into the skirt 47 the elastic tongues 59 and the ramps 51a tend to separate the two housing elements from one another. When the protrusions 61 cross the edges 51b the ramps 51c tend to facilitate the engagement of the male element 45 in the skirt 47 and when said protrusions 61 are engaged in the notches 55 the two elements 45 and 46 are locked.
  • the bar 53 In order to be able to separate the two elements, the bar 53 must be lifted by the gripping member 54 and when a pull is exerted on the male housing element 45 relative to the female element, the protuberances 61 pass under the projections 51.
  • the male box element 45 comprises an opposing device 65 molded in one piece with the body of said male element 45.
  • Each device comprises two parallel ribs 66 and 67 provided respectively with free extensions 66a, 67a, terminated by curved fingers 66b and 67b.
  • bosses 70 corresponding to the fingers 66b, 67b are provided, the bosses 70 having two ramps 70a, 70b, two stops 70c and 70d and a rounded part 70e.
  • the opposing device 65 operates in the same way as that of FIGS. 1 to 9, the fingers 66b, 67b crossing the stops 70c and 70d only when the protuberances 61 have crossed the edges 51b.
  • the box of FIG. 11 comprises a male box element 80, a female box element 81 with a skirt 88 provided with protuberances 83 intended to cooperate with a locking member 82 of the same type as that of FIG. 10.
  • the female housing element 81, exterior to the skirt 88 comprises an antagonist device 84 with two ribs 85 and 86 having free extensions 85a and 86a respectively terminated by curved fingers 85b, 86b.
  • An outer face of the male box element 80 has a boss 87 intended to cooperate with the device 84 and having two ramps 87a and 87b, two stops 87c and 87d and a rounded part 87e.
