Definitions

  • the present invention relates generally to a device for the distribution of wiring accessories intended for the equipment of electric cables in particular of cables with multi-strand conductor coated with an insulating sheath.
  • These wiring accessories may be lugs, comprising, specifically, for the connection to be established, an ear or a finger, as well as insulating sleeve ends.
  • the accessories in question are cable end caps, it is known that these include a tubular metal element and an insulating sleeve overmolding one end of the tubular element.
  • a tubular metal element and an insulating sleeve overmolding one end of the tubular element.
  • ferrules whose diameter of the tubular element varies between 1.4 mm and 2.5 mm respectively and whose diameter of the insulating sleeve varies between 3 mm and 4.7 mm respectively. It would be desirable to be able to distribute series of tips of different diameters with a single device, requiring little or no modification.
  • Patent FR-2 642 233 describes a device for distributing and crimping end pieces comprising toothed wheels and giving rise to a certain complexity of production.
  • the invention aims to simplify the distribution of wiring accessories.
  • each bar comprises at least one transverse branch and the device comprises in a housing at least one retaining piece which is elastically applicable on one end of the transverse branch.
  • Each bar preferably comprises two transverse branches located opposite one another, on both sides of the bar, each branch cooperating with a concavity of a cassette tongue.
  • the holding tabs are advantageously flexible and their concavities are arranged to allow the tongues to be separated after sufficient traction exerted on the strip by the advancing means.
  • One of the two tongues may advantageously have a boss constituting a ramp on which a transverse branch is applicable, this in order to separate the tab to facilitate the passage of the strip between the two tabs.
  • This device has the advantage of being able to distribute wiring accessories of different dimensions without modifying the housing as soon as the sum of the length of the bars and the diameter of the accessories is equal to the step in advance and the height of the transverse branches is independent of the above dimensions.
  • the strip is enclosed in a cassette, including the tabs, and designed so as to be able to be fixed removably on a crimping apparatus comprising the means for controlling the step by step advance of the strip, these means being applicable on at least one of the transverse branches.
  • the wiring end 4 includes a tubular metal element 5 intended to be engaged on the stripped end 7 of the conductive part of the electrical cable 2 to be fitted, and a sleeve made of insulating material 6 molded onto one end of the tubular element and covering the end of the insulating sheath 3 of the cable.
  • This cassette 9 comprises a box 9a of flat shape, substantially parallelepiped, with a rounded edge, comprising a front face 8 of small thickness and a cavity 14 of substantially cylindrical shape, and of height slightly greater than that of the end pieces.
  • the cassette is preferably molded from plastic.
  • the cavity 14 comprises a chute 13, of parallelepiped shape, intended to receive one end of the strip of end pieces.
  • the chute 13 is provided with an opening 15 allowing the outlet of the end pieces.
  • Two flexible tongues 10 and 11 of elongated shape are associated with the opening of the trough 13, by being connected for example to the internal walls of the trough 13, parallel to the strip, so as to come into contact with each side of the strip end caps at the sleeves.
  • a spring could be associated with at least one of the tabs to press it against the strip.
  • the tongues 10, 11 come from molding with the cassette.
  • the front face 8 has an orifice 12 opposite which the last end of the strip positioned by the tongues must be presented.
  • the orifice 12 allows the end of the cable to be crimped to pass through the end piece.
  • the casing 9a of the cassette has a rectangular opening 16 formed in its wall closest to the edge of the front face 8. This means of advance may be different, but it is important that it cooperates with the transverse branches of the bars. Part of the feed means can be mounted in the cassette.
  • the strip is formed of end pieces 21, axially parallel to each other, and of bars 17, 29 connecting two end pieces at the level of the sleeves and coming from molding with the sleeves.
  • the circles 21 and 22 respectively represent the sleeve of diameter d and the tubular metallic element of a nozzle.
  • Each of the bars in the form of a cross, comprises a longitudinal branch 18 and two transverse branches 19 extending normally to the axis of the end pieces, the branch 18 ensuring a detachable or breakable connection between two end pieces.
  • the height of the transverse branches 19 corresponds to the maximum diameter of the end pieces that the device is capable of distributing, while the length of the longitudinal branch 18 is adapted to the diameter of the end pieces so that the distance between the axes of two consecutive tips is constant (not constant).
  • end strips of different diameters can be housed in identical cassettes.
  • the tongues 10 and 11 have an elongated shape and each have, at one end and on the faces in contact with the strip, two bumps (23, 24 and 25, 26), of rounded shape.
  • these bosses (23, 24 and 24, 26) are arranged so as to form between them a concave shape in which one end of the transverse branch 19 of the last bar 17 can engage, as shown in Figure 5, and to allow the spacing of the tongues when exerting sufficient traction.
  • the tongues can, of course, have plugs of different shapes to grip the ends of the branches 19.
  • Figure 10 shows the passage of the ends 27, 28 of the transverse branches 30 of the next bar 29 on the bumps 24 and 26 of the tongues, before its engagement in the concavities delimited by said bumps ( Figure 11).
  • the strip is blocked by the bumps of the tongues 10 and 11 and the end piece 21 or 22 is positioned opposite the orifice 12 to receive the cable to be crimped.
  • the crimping device which can be in the form of pliers or a crimping unit, comprises a feed finger 31 which is for example in the form of an erasable square which can move both in translation along an axis 35 parallel to the strip and rotating around an axis 36 or 36 'parallel to the axes of the end pieces ( Figure 12).
  • FIG. 12 shows the position of the advance finger in different intermediate positions 31, 32, 33 and 34 between the advanced position 32 and the retracted position 34.
  • the finger bears against a transverse branch.
  • the intermediate positions 31 and 33 the finger is erased by bearing on a sleeve 37, then on the next transverse branch 38 without being able to drive the strip either in one direction or the other.
  • the finger is ready to push the strip, pressing on the next transverse branch 38.
  • the cyclic sequence of the positions is 34, 32, 31, 33.
  • the cassette is removably mounted on a crimping device which is in the form of a clamp 40 with a step feed finger 41, similar to the finger 31 which comes to be described, and engaging in the opening 16 of the cassette.
  • the clamp 40 also has two adjustable jaws 42, 43 for clamping the tubular element of a nozzle on the end of an electric cable.
  • the adjustable jaws 42, 43 have teeth of different sizes allowing them to adapt to the diameter of the end pieces.
  • the clamp comprises a thumb wheel 44 which makes it possible to simultaneously move the two jaws 42, 43 to position the teeth corresponding to the diameter of the end pieces contained in the cassette.
  • the jaws 42, 43 also have cutting parts which, at the same time as the crimping takes place, make it possible to detach the last sleeve from the strip.
  • the device according to the invention is not limited to a specific type of crimping device. It can be mounted on other devices such as an automatic nozzle fitting station comprising a means for driving the strip.
