Definitions

  • the present invention relates to a holder for a toroidal inductor integrated in the plug body of an electrical mains plug according to the preamble of patent claim 1.
  • a power plug with an integrated holder or receptacle for the current-compensated toroidal choke is known in connection with a so-called central plug from DE-OS 34 40 573.
  • the holder or receptacle for the toroidal core choke is designed together with the crossbar and the connector bridge as a one-piece molded part, the connector pins being inserted and fixed simultaneously with the injection molding of the connector bridge shape.
  • the insertion of the contact sleeves, the insertion of the toroidal choke and the connection of the connecting wires of the toroidal core choke to the contact sleeves or the plug pins are then carried out in successive operations.
  • the object underlying the present invention is now to provide a holder of the generic type with which the production can be optimized and maximized insofar as the individual operations for the completion of the basic unit consisting of crossbar, holder and plug bridge for the plug body each optimally can be done for yourself.
  • the two assembly units are each prepared and completed for themselves so that the holder is only created when the two are assembled, into which the toroidal inductor is then inserted or clipped and connected, in particular squeezed, with respect to their connecting wires to the contact sleeves and the plug pins (crimped).
  • This first assembly unit 1 essentially consists of a round plate 2, which - see FIG. 3 - serves as a receptacle or support for a toroidal core choke.
  • the round plate 2 has two resilient hook elements 3 arranged diametrically to one another and projecting from the plane of the plate 2.
  • a projecting web 4 adjoins the circumference, which in turn carries a cross web 5 at the end.
  • This transverse web 5 is arranged transversely to the direction of the web 4 and has receiving bores for the contact sleeves 6 to be used in production.
  • a block 7 which also projects outwards and has a particularly rectangular opening 8 at a distance from the round plate 2.
  • the first assembly unit 1 described so far is manufactured as a separate molded part and is equipped as an individual part with the contact sleeves 6 and connected, in particular crimped, to the cable wires of the connecting cable.
  • FIG. 2 shows the second assembly unit 10, the essential component of which is a rigid, approximately slot-shaped (see FIG. 3) connector bridge 11 with molded connector pins 12.
  • the connector pins 12 are molded as is known so that they protrude on both sides of the plug bridge 11 - on the one hand, the plug pins that can be inserted into a power socket protrude and, on the other hand, these plug pins protrude from the back of the plug bridge 11 and offer a hollow cylindrical receptacle 12 'for the connecting wires the toroidal choke (see Fig. 3).
  • the plug bridge 11 additionally has a bridge-like projection 13 centrally between the latter hollow cylindrical receptacles 12 '.
  • This projection 13 extends approximately to half the connector bridge width and merges into a nose-like extension 14 at a distance from the connector bridge 11, the cross section of which is designed and dimensioned to be complementary to the opening (8 in FIG. 1) in the block (7 in FIG. 1) .
  • FIG. 3 shows the mounting 20 consisting of the assembled mounting units 1 and 10 and completed in three views.
  • the bracket 20 is first assembled in that the first assembly unit 1 with its opening 8 is plugged onto the complementary nose-like extension 14 of the second assembly unit 10. This gives a positive connection between these two assembly units 1 and 10 and a one-piece assembly body for final assembly and final production.
  • This completion now consists in that a toroidal core choke 21 with its two coils 22, 23 is placed over the hook elements 3 of the first assembly unit 1 and is thus placed on the round plate 2.
  • the connecting wire pairs 24/25, 26/27 projecting from the coils 22, 23 are then connected, in particular crimped, to the corresponding contact sleeves 6 or hollow cylindrical receptacles 12 'of the connector pins 12.
  • the holder 20 thus completed is then finally placed in an injection mold and overmolded with plastic - the product is then a plug with two plug pins for insertion into a mains socket and a connecting cable (connected to the contact sleeves).
  • FIGS. 4 and 5 A second exemplary embodiment of the assembly units 1 and 10 will be explained with reference to FIGS. 4 and 5. Relative to the (first) embodiment of the holder according to the invention shown in FIGS. 1 to 3, the difference and advantage is that the holder according to the second embodiment - Viewed axially - builds shorter because the projection of the second mounting unit 10 is integrated in the region of the plug bridge 11. This has the advantage that material can be saved overall.
  • FIG. 4 shows - in analogy to FIG. 1 - a first assembly unit 1 with a round plate 2 for receiving a toroidal core choke between the resilient hook elements 3.
  • the round plate 2 cries on one side the projecting web 4 with the cross web 5 and the contact sleeves 6 on.
  • a protruding projection or block 7 ' is provided in the same way as in the exemplary embodiment according to FIG. 1, which also comprises a rectangular opening 8'.
  • the extension 7 ' is stepped towards the outside, so that only a narrow web 9 remains as the outer boundary of the opening 8'.
  • the connector bridge 11 lies against this narrow web 9 laterally.
  • the second assembly unit 10 is provided on the inner peripheral bead of the opening 8 'protruding nose 16.
  • Fig. 5 shows - in analogy to Fig. 2 - a second assembly unit 10. It consists of the connector bridge 11 with the molded connector pins 12 which protrude from the rear to the connector bridge 11 and provide a hollow cylindrical receptacle 12 'for the connecting wires of the toroidal choke.
  • the complement to the opening 8 'or the approach 7' of the first assembly unit 1 is not formed as a projection (13 in Fig. 2), but as a laterally incorporated into the connector bridge 11 groove 15, the to the top with the contact sleeves 12 'is open. This results in a groove 15 which is open at the top on two sides and onto which the first assembly unit 1 with the web 9 and the adjacent sides can be attached. Through the groove 15, a projection 16 is formed, which engages positively during assembly in the opening 8 '.
  • the two assembly units 1 and 10 explained with reference to FIGS. 4 and 5 are each manufactured individually. During assembly, both assembly units 1 and 10 are joined to one another or plugged onto one another (see arrow x) in such a way that the second assembly unit 10 in the region of the groove 15 and the projection 16 into the opening 8 'and on the narrow web 9 of the first assembly unit 1 is pushed. The plug bridge 11 then closes laterally with the base plane of the round plate 2 (cf. Y).
