Definitions

  • the invention relates to a power plug according to the preamble of claim 1.
  • Power plugs of this type are known (DE-B-31 48 351).
  • the so-called inflow immunity Consumer electronics devices, especially television sets, e.g. in the Federal Republic of Germany in the VDE regulation, Official Gazette No. 69, the so-called inflow immunity. It is known and has proven to be advantageous because of the antenna effect of the power cord to insert a coil between each of the two neutral and phase conductor plug pins and a connecting terminal for the associated connecting cable wire in the connector housing, that is to say to accommodate it in the connector, in order to achieve this inflow immunity.
  • the two coils are parallel to one another and are separated from one another by a separator. Together with blocking capacitors, they form a line filter.
  • the blocking capacitors can consist of the relatively large parasitic capacitances which are present in the plug between the coils and lines which are arranged parallel and at a distance from one another.
  • suppressor plug in the form of an adapter plug known for two-wire device connection cable, which consists of a ring core, two wound thereon in opposite directions, each in the cable from a plug to a socket for a cable wire coils and a capacitor connected in parallel to the two pins.
  • the coils form a line filter together with the capacitor (DE-A-2 042 342).
  • This interference protection device requires a shielded cable and is built into its three-pin connector. It consists of a toroid and two symmetrical windings wound thereon, each of which is connected to the line of the phase conductor and the neutral of the connecting cable, as well as from at least one side of the coil arrangement between the line of the phase or neutral and the line of the earth conductor switched capacitors, which together with the coils form a line filter.
  • the capacitors consist of the distributed capacitance of the cable, which is relatively large because of the earth conductor and the shield connected to it (EP-A2-90 774).
  • the coils used, together with capacitors, form an LC low-pass filter only the one mentioned above in accordance with DE-B-31 48 351 being usable for two-wire, unshielded device connection cables.
  • the invention has for its object to provide a particularly compact mechanical plug for the inflow resistance in mechanical design, which is also characterized by an even better interference suppression compared to the known generic suppressor according to DE-B-31 48 351.
  • the parasitic capacitances present in the plug and along the device connection cable are negligibly small compared to the inductances of the two coils of the toroidal core choke, so that the plug, unlike the known interference protection devices, does not contain an LC filter. Rather, the desired interference suppression or inflow immunity to interference is brought about in a novel conception with the inductances of the toroidal core choke alone, and this also with a better effect than the known interference suppressor according to DE-B31 48 351.
  • the toroidal core which is held securely in the plug in turn fixes the windings mechanically precisely in the plug, which results in a particularly compact mechanical structure in which the individual parts are precisely defined relative to one another.
  • the subclaims relate to preferred configurations of the power plug according to claim 1.
  • the invention is explained in more detail below with reference to the drawing using an exemplary embodiment.
  • the drawing shows a power plug according to the invention in plan view and in side view, the connector housing being omitted and only being indicated in its outline by a dashed line.
  • the (standardized) connector pins are labeled 1.
  • the connector pins 1 are injected into a base plate 2, which in turn, integrally molded, has a receptacle 3 for a toroidal core choke 5, which also carries solder or crimp contacts 4 for the electrical connection of the wires 8 of the leading connection cable.
  • the receptacle 3 holds the core of the toroidal choke firmly in place.
  • the wire ends 6 of the coils, which form a current-compensated toroidal choke with the toroid are electrically connected on the one hand to the plug pins 1 and on the other hand to the soldering or crimping contacts 4 by suitable methods (welding, ultrasound welding or soldering).
  • mains supply cables for consumer electronics devices are provided with a Euro plug, which allows any European socket to be used.
  • Such cables are usually assembled in such a way that a plug base which is soldered or welded to the wires of the connecting cable is placed in an injection mold and then encapsulated with a relatively elastic plastic.
  • the power plug according to the invention holds the receptacle 3, the toroidal choke 5 and the contacts 4 for the wires of the connecting cable during the spraying process in a fixed position with respect to the base plate 2 with the plug pins 1, so that these parts can not be accidentally moved when encapsulated with plastic.
  • the core of the toroidal core choke together with the receptacle, results in a mechanically very compact structure, in which the coils are also immovably fixed, and the current-compensated toroidal core choke 5 also results in particularly good inflow immunity to interference.
