Definitions

  • the present invention relates to a coil for filiform products, in particular for soldering wire, of the type comprising a calibrated hub in two axially spaced parts for mounting the coil on the shaft of a reel, and a wire-based frame.
  • metallic which. are folded and fixed together so as to form together the two side cheeks of the coil and spacers which extend between the two side cheeks, parallel to the axis of the coil, and which serve as a support for the filiform product, each of the side cheeks having spokes, the internal ends of which are fixed to the hub.
  • coils or drums have essentially been proposed for a few years, essentially constituted by a frame based on metal wires.
  • Such coils or reels are for example described in French patents No. 2,223,293, 2,272,941, 2,299,258, 2,311,741 and its certificate of addition No. 2,385,634, 2,369,198 and 2,437,370. that the coils based on metal wires bring a significant improvement from the point of view of the weight and the manufacturing cost compared to the previous coils, they nevertheless have some drawbacks. This is how some of the coils or reels previously known from. metal wires, do not have a calibrated central hub and require an adapter for their installation on the shaft of a reel.
  • the present invention therefore essentially aims to provide a coil comprising a frame based on metal wires, which is much lighter and more economical than the plastic coils, but which retains the advantages of interchangeability and electrical isolation.
  • the coil according to the present invention is characterized in that the hub is constituted by two washers of an insulating material, having holes which extend radially in the washers and in which the internal ends of the spokes are engaged.
  • each of the two washers may have, on one side, slots which each communicate with one of the holes and through which the spokes are engaged in the holes, perpendicular to the axis of these, by elastic snap-fastening.
  • Figure 1 is a perspective view showing a coil according to the present invention, the upper part of Figure 1 showing an eight-spoke embodiment, while the lower part of Figure 1 shows a six-spoke embodiment.
  • the coils shown in FIGS. 1 and 5 essentially comprise a hub 1, made of an insulating material, and an armature 2 based on metal wires which are fixed to the hub 1 as will be explained below.
  • the frame 2 is made up of several similar elements 3, made of metal wire, for example steel wire, which are bent and fixed together so as to form together the two lateral cheeks 4 and 5 of the coil and the spacers 6 which extend between the two cheeks 4 and 5 parallel to the axis of the reel, at equal distances from this axis, and which serve as a support for the filiform product to be wound on the reel.
  • metal wire for example steel wire
  • Each of the two cheeks 4 and 5 has a substantially circular peripheral part and a certain number of spokes which extend radially between the hub 1 and the circular peripheral part of the corresponding cheek, for example eight spokes as shown in the upper part of the figures. 1 and 5 or six spokes as shown in the lower part of Figures 1 and 5.
  • each wire element 3 has a straight part 3a forming a radius of one of the two cheeks 4 and 5, and a part 3b in an arc, having a corresponding arc length. at an angle of 45 ° or 60 ° depending on whether the cheek has eight or six spokes, respectively.
  • the free ends of the parts 3a are engaged in blind holes 7 (FIG. 9) provided in the ends of the hub 1. As shown in FIG.
  • each metal wire element 3 can have, at the end of its part 3b, which is opposite to the part -3a, a short part 3c which is curved radially inwards and which comes to bear along the part forming the radius 3a of the element adjacent wire 3 belonging to the same lateral cheek 4 or 5, as shown in the upper part of FIG. 1, part 3c of an element 3 being fixed by spot welding or by arc welding to part 3a of adjacent element 3.
  • the parts 3c of FIG. 2 can be omitted and, in this case, the free end of the part '3b simply comes to bear on the external end of the part forming a radius' 3a of the adjacent wire element 3, to which it is fixed by arc welding, as shown in the lower part of FIG. 1.
  • each spacer 6 is formed by a straight piece 3d of metal wire, the ends of which are fixed, for example by arc welding, respectively on the parts forming radius 3a of two elements 3 arranged facing each other and each belonging to one of the two lateral cheeks 4 and 5.
  • the pieces of 3d wire forming the spacers 6 are fixed to the parts 3a of the wire elements 3 at the same distance from the axis of the coil, this distance possibly varying, as shown in phantom in Figure 1, depending on the amount of welding wire that you want to be able to wind on the coil.
  • FIG. 4 shows an alternative embodiment of a metal wire element 3 capable of being used to make the frame 2 of the coil according to the present invention.
  • the two metal wire elements 3 which are mutually opposite and which respectively belong to the two lateral cheeks 4 and 5 of the coil, and the spacer 6 are constituted by a single piece of metal wire suitably bent as shown in FIG. 4.
  • the parts 3c of the metal wire are longer than in FIG. 2 and are joined together by the part 3d forming the spacer 6.
  • Figures 5 and 6 show another possible way of making the armature 2.of the coil.
  • the armature 2 consists of several metal wire elements 3 such as that shown in FIG. 6.
  • the element 3 in FIG. 6 successively comprises a first straight part 3a oriented radially and forming an inner part of a ray of one of the two lateral cheeks 4 and 5, then a straight part 3d, bent at 90 ° and oriented parallel to the coil axis, which forms a spacer 6, then another straight part 3a 2 oriented radially and forming a outer part of a radius of the other lateral cheek 5 or 4, then a part 3b in an arc forming a part of the outer peripheral edge of said other lateral cheek, and finally a terminal part 3c curved radially inwards and intended to be fixed, for example by spot welding or by arc welding, to the part 3a 2 of the adjacent element 3 as shown in the upper part of FIG.
  • the part 3c of the element 3 of Figure 6 can optionally be omitted as shown in the lower part of Figure 5 and as already explained in connection with Figures 1 and 3. As in the previous embodiments, the free end of part 3a of the element 3 of FIG. 6 is engaged in one of the holes 7 (fig ure 9) of the hub 1 of the coil.
  • the hub 1 can simply consist of two axially spaced washers 8 and 9 made of insulating material.
  • the washers 8 and -9 can for example be made of molded plastic.
  • Such a molded plastic washer is shown in FIGS. 7 to 9 which are on a larger scale than FIGS. 1 and 5.
  • each washer 8 or 9 has a relatively thin thickness and has internal and external peripheral reinforcement lips 10 and 11.
  • the blind holes 7, intended to receive the free ends of the parts 3a (FIGS. 2, 3 and 4) or 3a l (FIG. 6) of the wire elements 3, are formed in bosses 12 which are regularly angularly spaced on one of the two faces of the washer 8 or 9 and which extend radially towards the inside from the outer peripheral edge 11 of the washer 8 or 9 up to a certain distance from its inner peripheral lip 10.
