Definitions

  • the present invention relates to an electrical plug for connecting two elements of an electrical cable with two pins each having a connection means, said pins being fitted in two housings provided in an insulating insert, and said plug being electrically insulated by an external overmolding.
  • the invention finds a particularly advantageous application in the general field of connectors, and in particular in that of bipolar and bipolar + earth plugs when a high degree of insulation is sought.
  • this type of known electrical plug has the drawback of insufficient electrical insulation with respect in particular to flying strands which could escape from the connection drums and thus come into contact with the overmolding and even be flush with it. particularly long flying strands, which is not acceptable for safety reasons.
  • German patent application DE-A-3 807 309 proposes to provide the electrical plug of the preamble with an intermediate insulating shell covering the insert and intended to receive said external molding.
  • the insulating shell placed intermediate between the insert and the overmolding, prevents any flying strand, whatever its length, from coming into contact with the overmolding.
  • very long flying strands cannot, at worst, leave the plug only through the front part of the plug, i.e. on the side of the pins, a location which is not accessible when the electrical plug is connected.
  • the positioning of the shell on the insert requires that one end of the cable be introduced through a hole made in the shell, which can be done only manually, excluding any possibility of automatic assembly of the assembly.
  • the technical problem to be solved by the object of the present invention is to produce an electrical plug for connecting two elements of an electrical cable with two pins each having a connection means, said pins being fitted in two housings arranged in a insulating insert, and said plug comprising an intermediate insulating shell covering said insert and intended to receive an external overmolding of insulation, electrical plug which would allow very easy mechanization of the assembly of all the parts constituting it.
  • the solution to the technical problem posed consists, according to the present invention, in that said shell comprises means for lateral introduction of the shell onto said cable.
  • said means for lateral introduction of the shell onto the cable consist of a lateral groove.
  • said lateral groove provides walls forming means for immobilizing the elements of the cable in the electrical plug. In this way, the lateral groove performs a double function, that of passing the cable through the shell and that of retaining the elements of the cable.
  • said insulating shell has lateral ribs for stiffening said overmolding.
  • this advantageous arrangement reduces the cost of the electrical plug object of the invention since the material constituting the shell, polypropylene for example, can be significantly cheaper (about 3 times) than that constituting the insulating insert (polyamide for example) .
  • Figure 1 is a perspective view of an insert and a shell of a bipolar electrical plug according to the invention.
  • FIG. 2 is a perspective view, in the direction of arrow F1, of the shell of FIG. 1.
  • FIG. 3 is a perspective view of the assembly constituted by the insert and the shell of FIG. 1.
  • Figure 4 is a perspective view of the electrical plug of Figure 1 after overmolding.
  • Figure 5 is a sectional view of the insert of a bipolar electrical plug + earth according to the invention.
  • Figure 6 is a bottom view of the plug of Figure 5.
  • Figure 7 is a sectional view along line II-II of the sheet of Figure 5.
  • FIG. 1 shows, in perspective, an electrical plug of the bipolar type for connecting two elements 101, 102, the neutral and the phase for example of an electric cable 100, with two pins 201, 202 each having a connection means which, in the embodiment of Figure 1, is, without limitation, a barrel 211, 212 of connection intended to receive strands 111, 112 stripped of the element 101, 102 corresponding.
  • the fixing of said strands 111, 112 in the drums 211, 212, of connection is obtained, in the case of FIG. 1, by crimping through the slots 311, 312.
  • the pins 201, 202 which can be made of brass, are fitted by ultrasound, overmolding, or any other means, into two housings 301, 302 arranged in an insulating insert 300 made of molded polyamide for example.
  • the electrical plug comprises an insulating shell 400 intended to cover said insert 300 and to receive an overmolding 500, shown in FIG. 4, which makes it possible to ensure the external insulation of said plug.
  • the shell 400 thus placed in the intermediate position between the insert 300 and the isolation overmolding 500, offers maximum electrical insulation of the plug, in particular against the flying strands which could escape from the connection drums 211, 212.
  • the enveloping nature of the shell 400 has the advantage of forcing particularly long flying strands out of the plug on the side of the pins, in a place where, given overmolding, they do not present any danger when the plug is connected.
  • the insulating shell 400 has lateral ribs 401, 402 for stiffening the isolation overmolding, which makes it possible to reduce the cost price of the plug.
  • the material constituting the shell polypropylene for example, being in fact less expensive than the polyamide of the insert in which said stiffening ribs are usually made.
  • Figure 1 also shows that the insulating insert 300 has a recess 320 limited by two side partitions 331, 332 and inside which are housed the elements 101, 102 of the cable 100 in their part between the cable and the drums. connection.
  • the insulating shell 400 has walls 421, 422 which come to bear against said lateral partitions 331, 332 when the shell is placed on the insert.
  • the walls 421, 422, acting as immobilization means form with the recess 320 retaining means in a baffle with respect to the elements 101, 102.
  • This baffle system makes it possible to completely preserve the connections ensuring the immobilization of the elements during a brutal pull of the cable.
  • the shell 400 comprises means for the lateral introduction of the said shell onto the said cable 100.
  • the said lateral introduction means are constituted by a lateral groove formed by the two walls 421, 422 and one third wall 423. The shell can then be put in place very easily, it suffices for this to present it on the cable in a lateral movement illustrated by the arrow F1 in FIG. 1, then to bring it, according to arrow F2, on insert 300 to its final position.
  • the lateral groove provides both the means for introducing the shell onto the cable and the walls of the immobilization means.
  • the insulating shell 400 is held in place using fixing means which are constituted by two fixing lugs 330 arranged on either side of the insert 300, one of said pins cooperating with a slot 410 which, as shown in Figure 2, is arranged in said shell on the wall 423 of the lateral groove.
  • fixing means which are constituted by two fixing lugs 330 arranged on either side of the insert 300, one of said pins cooperating with a slot 410 which, as shown in Figure 2, is arranged in said shell on the wall 423 of the lateral groove.
  • the insertion of said lug into the slot 410 is carried out by elastic deformation of the shell, the latter resuming its initial shape when the lug 330 is engaged in said slot.
  • the presence of two pins, only one of which is actually used, makes it possible to introduce the shell onto the insert in any direction, thereby increasing the ease of assembly of the plug.
  • Figures 5 and 6 show an alternative embodiment of the electrical plug described above with reference to Figures 1 to 4, for the connection of a cable 100 comprising, in addition to the phase and the neutral 101, 102, an element 103 for setting To the earth.
  • the insulating insert 300 also includes a third housing 303 in which is disposed a means 350 of electrical contact in the shape of a barrel, opening out to the outside of the insert by a fixing means 360, a rivet for example, to a ground rail 600.
  • the strand 113 of the grounding element 103 is crimped into the barrel 350, through a light (not shown), equivalent to the lights 311, 312 of FIG. 1.
  • the insert 300 comprises two separate recesses 321, 322 intended to house the elements 101 and 102 respectively.
  • the bottom view represented in FIG. 6, shows the arrangement of the earth rail 600 with respect to the insert 300 and the overmolding 500 when the electrical plug is completely assembled.
  • the three elements 101, 102, 103, phase, neutral and earthed have an identical length so that during assembly, due to the sliding of the hull on the insert and blocking of the phase and neutral elements by said baffles, the grounding element 103 has an extra length, or soft strand, of safety, as illustrated in FIG. 7.
  • a brutal pull on the cable 100 induces the rupture of at least one of the phase or neutral elements before the earthing element.
  • the insulating insert 300 comprises introduction means, constituted by cones 341, 342, 343, making it possible to introduce the elements 101, 102, 103 of the cable 100 with respect respectively to the means 301, 302 for connection and to the means 350 for electrical contact.
