Definitions

  • the present invention relates to connectors electrical cables, and it concerns more particularly a connector which makes the connection a cable by perforating the insulating sheath of this cable, which makes it possible to get rid of a prior operation of stripping, as well as a method of manufacturing such connector.
  • a connector using the same connection principle, but which includes a base fixing and, extending above this base, a tongue which is provided with perforation teeth and receives a stirrup.
  • the rectangular base is intended for be placed in a housing, against the bottom thereof, in being slid and then snapped behind ribs which lock the connector in this position.
  • the base and the tongue are formed in the same blank of sheet metal, cut so that the base is extended by the tongue.
  • the latter is folded over the base, which results in the formation of microcracks and degradation of the electrical connection between the base and the tongue. Also was it necessary to provide a weld associating the end folded from the tongue to the base, and thereby achieving the electrical contact required.
  • the invention therefore aims to reduce the width of the sheet a tongue in which is formed a toothing of perforation.
  • the invention relates to a connector for the connection of a conductive cable with a sheath insulating, this connector comprising a sheet blank in which a tongue is formed and, on this tongue, a perforation teeth, said tongue being intended to receive a bracket with a cable clamping screw against the toothing for perforating the insulating sheath, characterized in that the teeth are formed by at least one punctured hole in the tongue.
  • a connector according to the invention is illustrated, in view exploded, in Figure 1. It has three main elements, namely a base 1, a bracket 2 and a fuse holder 3.
  • the base 1 is obtained by forming a sheet blank of a all in one piece, cut so as to have the general shape of a band.
  • the base 1 has two transverse folds 4 and 5, beyond which extend end portions 6 and 7, rectangular and substantially parallel to each other.
  • a tongue 9 is cut from this base 6, according to the length of it.
  • the base 6 extends horizontally and forms the lower part of the connector, it being understood that this is not there that a convention, the orientation of the connector in place can be completely arbitrary.
  • transverse folds 10 and 11 are formed in the tongue 9, to near its base, so that its central part extends away from the base 6, substantially parallel thereto.
  • This central part 12 has three punctures 13 arranged along the median and longitudinal line A-A 'of the tongue 9, each of them being provided with four teeth 14, directed upwards, which are part of a set of teeth 15.
  • the tongue 9 ends with a part 16 curved towards the base 6. It is intended to receive the bracket 2, in extruded aluminum, placed at the level of the part central 12, so that the clamping screw 17, with head breakable, with which it is provided, moves towards the tip of teeth 14 when screwed.
  • the tongue 9 gives way to a slot 18 delimited by two fixing lugs 19 which form a fork ending at the end 8.
  • two fixing lugs 21 extend on each side of the fold 4.
  • the fuse holder On the upper face of the end portion 7, which extends above the base 6, the fuse holder is welded 3.
  • the latter has two substantially vertical walls 22, which are parallel to each other and connected elastically by an annular portion 23, so as to jointly delimit a slot 24, widening upwards, capable of receiving a knife-shaped terminal of a fuse.
  • the two walls 22 are also connected by an elastic ring 25, open, which is willing to participate in the stiffness that occurs when the slot 24 is spread.
  • the end portion 7 has a hole 26 for receiving a stud 27 also housed in a hole 28 drilled in the fuse holder 3.
  • a sheet blank from a plate made of material conductor, for example copper, aluminum or a copper or aluminum based alloy.
  • the 13 punctures are then drilled using a punch 29 with a conical head, illustrated in Figure 3. Indeed, it was found that, from surprisingly, such a punch made it possible to obtain, at the level of each punctured 13, a substantially regular toothing, with four teeth. Then the sheet blank is put in shape by successive folding, until the base 1 is obtained.
  • punctures 13 can be formed before or after the cutting operation the shaping operation. They can also be performed simultaneously with one or the other of these two operations.
  • the fuse holder 3 is also obtained by cutting and shaping of a sheet blank.
  • the base 1 and the fuse holder 3 are assembled by welding, after fitting the stud 27 in the holes 26 and 28.
  • To complete the construction of the connector there remains more so than to provide it with the elastic ring 25 and the bracket 2 provided with the clamping screw 17.
  • the tongue 9 is successively tilted up around fold 10 (arrow F), which allows you to put on the stirrup 2, then folded back to its initial position.
  • the connector thus produced is placed in a hollow housing, delimited by the walls of a support 30, seen in section, comprising four ribs 31 and 32, parallel to the bottom 33 of this housing.
  • the two ribs 31 are respectively arranged at the two corners of the same end of the housing, while the ribs 32, offset axially with respect to the ribs 31, each extend at from one of the two side walls of this housing.
  • the bottom 33 has two holes 34 located at the right of the ribs 31.
  • the base 6 is placed between the bottom 33 and the ribs 31 and 32 which thus retain the connector in its housing.
  • the connector is installed on the support 30 by sliding, at first, the two fixing lugs 21 each in a hole 34, under a rib 31, then, in a second time, by folding the base 6 against the bottom 33, until that the two fixing lugs 19 snap behind the ribs 32.
  • a fuse 35 is connected to the connector by one, referenced 36, of its two terminals, which has the form general of a knife and is inserted into the slot 24.
  • This clamping screw 17 presses the conductive cable 37 against the teeth 14, which, from this fact, anchor in the metallic core of it in perforating the insulating sheath 38.
  • a connector according to a variant of realization of the invention presents punctures 39 which each have two teeth 40 and have been obtained by a punch 41 illustrated in FIG. 6.
  • the head of this punch 41 has two sections delimiting instead of their intersection a end edge 42.
  • the head of the punch used to form the punctures may have more than two sides, for example three or four, which jointly delimit a point.
  • the punch 29 with conical head has the advantage of being particularly simple.
  • the connector can be formed in a single sheet blank, although the use of two sheet blanks, shape to obtain the base 1 and the fuse holder 3, then welded, is advantageous insofar as it makes it possible to reduce the importance of the material falls which result from their cutting in a plate. For example, it is particularly easy to place side by side, on a sheet of material first, so as to optimize the use of it, the cutting plots of several bases 1, since these lines delimit substantially bands.
  • punctures which are aligned along the line median and longitudinal of the tongue in the examples previous, can be arranged differently. They can, by example, be alternately distributed on either side of this midline or slightly offset to one side of it.
