Definitions

  • the present invention relates to an electrical appliance, in particular a household electrical appliance, with an essentially closed housing and with a power supply cable formed from a plurality of conductors and connected to the power consumer.
  • the device-side ends of the power supply cable are clamped to the contacts by screws. In another embodiment, they are also soldered, plugged in or struck. All types of fastening are very labor intensive. In addition, tensile and compressive forces must be prevented from being transmitted from the power supply cable to the clamping or soldering connections.
  • the cable is clamped by means of a clamp formed from two half-shells or fixed by a labyrinth, which increases the workload even further.
  • the connection points are usually inside the housing.
  • the power supply cable is therefore permanently and captively installed on the electrical device.
  • the present invention has for its object to provide an electrical device of the generic type so that the assembly of the power supply cable is significantly simplified, with the aim that the assembly is possible without manual manipulation.
  • an insulating body is provided in the interior delimited by the housing, that in the insulating body one of the number of conductors of the power supply cable corresponding number of contact elements connected to the conductors are arranged, which protrude from an outer surface of the insulating body , and that the insulating body is assigned a fixed contact plate in the interior of the device, which is provided with contact means which are electrically conductive with the contact elements of the insulating body.
  • the conductors of the power supply cable consist of plastic-coated copper wires, which are exposed over a predetermined length for connection to the contact elements of the insulating body at the end of the device.
  • a corresponding manufacturing process for the insulating body not only anchors the contact elements, but also the conductors in the insulating body.
  • the connection between a conductor and the contact element can no longer be released after production.
  • the particular advantage is that the contact elements protrude from an outer surface, so that the insulating body can be inserted particularly easily into the contact means of the contact plate. Even when forces are exerted on the power supply cable the connection of the conductors to the contact elements remains unloaded.
  • the design according to the invention means that the previously common clamping of the power supply cable can be dispensed with.
  • the insulating body can be designed for such an assembly.
  • the production of the insulating body is particularly simple if it is designed as a molded body made from a plastic injection molding process, which can be seen in the sense of a solid part.
  • the contact elements are inserted in a suitably designed tool and connected to the exposed ends of the conductors.
  • the power supply cable protrudes into the space described by the contact elements. After the plastic injected into the tool has hardened, there is a ready-to-connect, one-piece connection part formed from the power supply cable and the insulating body.
  • latching means engaging behind the insulating body are formed on the inside of the housing or on a removable bottom, which additionally protect.
  • the insulating body consists of at least two insulating body parts which are connected to one another by connecting means in a detachable or non-detachable manner.
  • the insulating body parts can then be connected to one another after the connection of the conductors of the power supply cable to the contact elements. If the insulating body parts are detachably connected to one another, the insulating body can be opened for inspection if a defect occurs.
  • the particular advantage is that the individual insulating body parts can be designed so that the connection of the conductors of the power supply cable to the contact elements can be checked before the individual parts are assembled.
  • the insulating body should expediently consist of only two insulating body parts, the contact elements then being arranged in one insulating body part.
  • FIG. 1 shows a generally known and therefore not explained in detail household coffee machine, which is equipped with a housing 10 made of plastic and a base 11 that can only be removed with a special tool.
  • the bottom 11 is fastened to the corresponding edges of the housing 10 in a manner that is not explained in detail.
  • the electrical connection between a power supply cable 12 and the power consumers (not shown) of the electrical device is provided in a corner formed from a side wall of the housing 10 and in the bottom 11.
  • the bottom 11 is provided with an opening 13 through which the power supply cable 12 is guided.
  • the conductors or devices of the power supply cable 12 are not shown.
  • Household appliances are usually operated with the mains voltage of 220 volts. A three-wire power cable is then required.
  • three contact means designed as contact sockets 14 are provided on the inside on the bottom 11, three contact means designed as contact sockets 14 are provided. These are electrically connected to the power consumer of the device via cables, not shown.
  • the end of the power supply cable 12 lies in an insulating body 15 which is provided with three contact elements 16, which extend over the entire height and are designed as contact tongues 16 or contact pins, which protrude so far from the lower end face facing the base 11 and the power supply cable 12 that them into the contact sockets 14 are insertable.
  • the contact tongues 16 also protrude from the upper surface, which is parallel to the lower surface. This supernatant is meaningless for the function.
  • the power supply cable 12 and the conductors are firmly anchored in the insulating body 15.
  • the insulating body is preferably made of a plastic, so that a short circuit is impossible.
  • the insulating body 15 is engaged behind by two latching means designed as latching hooks 17.
  • the locking hooks 17 are at right angles to the floor 11 and are also integrally formed thereon. They engage behind the upper end face of the insulating body.
  • locking tongues can also be used which engage in locking recesses in the insulating body 15.
  • the cross section of the insulating body 15 is an irregular, trapezoid-like hexagon. Other cross-sectional shapes are conceivable and depend on the number of conductors of the power supply cable 12 or the number of contact tongues 16.
  • the insulating body 15 shown in Figure 4 is in two parts.
  • the two insulating body parts are identified by the reference numerals 18 and 19.
  • the contact tongues 16 are arranged in the insulating body part 18.
  • the other insulating body part 19 can be seen in the sense of an openable and closable cover, since this insulating body part 19 is pivotally connected to the insulating body part 18 in a manner not explained in more detail by means of a film hinge is.
  • the insulating body part 19 On the side opposite the film hinge, the insulating body part 19 has a central latching hook 20 which, in the closed position, engages in a corresponding latching recess in the insulating body part 18 or engages behind a nose.
  • connection through the film hinge is that, despite the two-part design, the insulating body 15 can be handled like a one-piece component.
  • one or more locking hooks could be provided on two opposite sides.
  • the insulating body parts 18, 19 could also be connected to one another, for example, by screws or by rivets.
  • the detachable connection has advantages in terms of inspection and repair despite the higher effort.
  • the insulating body 15 It is not necessary for the insulating body 15 to be a solid part, but it can also be designed as a housing if contact with the current-carrying conductors or the contact tongues 16 is prevented.
  • the contact tongues 16 protrude from the end face which is to be assigned to the power supply cable 12. It is thereby achieved that the contact tongues 16 are drawn into the contact sockets 14 of the printed circuit board by tensile forces acting on the power supply cable 12. Depending on the type of device, however, it may be necessary to lead the power supply cable 12 into the insulating body 15 at another location or area. These opportunities are shown in Figure 5.
  • the power supply cable 12 shown in solid lines is inserted into the insulating body 15 at the end face opposite the contact tongues 16.
  • the power supply cable can also be assigned to the outer surfaces that run parallel to the contact tongues 16. Other options are conceivable.
  • the contact sockets 14 are part of a contact plate, which can be designed as desired. In the exemplary embodiment shown, it is fastened on the inside to the bottom 11.
  • the arrangement of the locking means on the bottom 11 offers the great advantage that the contact elements can be joined together with the contact means when the bottom 11 has not yet been installed.
  • the latching means and the contact plate are fastened to an inner surface of a side wall or a cover. It can be seen from FIGS. 2 and 4 that the contact tongues 16 of the insulating body 15 are pulled firmly into the contact sockets 14 when tensile forces act on the power supply cable 12. Since the power supply cable is firmly embedded in the insulating body 15 over a relatively long length, no forces are transmitted to the connection of the conductors of the power supply cable 12 and the contact tongues 16 in all embodiments.
