Abstract

In the power supply, a central feed line supplies power to multiple contacting points, from which the individual electrical components are directly supplied by means of loopings and/or taps. <IMAGE>

Description

The invention relates to a power supply for household appliances, in particular floor care devices, in which a central feed line supplies multiple contacts and from there the individual electrical components are individually supplied directly.

Such power supplies have the purpose of distributing all electrical supply lines, such as supply lines and various leads to the individual components in the device in a clean and clear manner from a central distribution point, so that the protective provisions for the users of such devices are observed.

Power supplies are known which are designed as a large-volume flat plug distributor plate, with all individual components each having a separate tap via so-called flat plug sleeves. So-called clamping cut contacts for contacting insulated special wires, in particular enamelled wires, are also known.

The disadvantage here is that all electrical lines end in the respective contact and a large number of contacts is therefore necessary to supply all components electrically. This also results in a considerable space requirement for such distributors. This also applies to the clamping contacts mentioned above.

The object of the invention is to provide a power supply which avoids the aforementioned disadvantages and which has only a single supply line, which is only split at certain points over several connecting lines, the distribution points while maintaining all prescribed safety measures can be reduced in their physical dimensions.

This object is achieved by the characterizing part of claim 1.

Further advantageous refinements are described in the subclaims.

The invention will be described below with reference to the drawings.

Show it:

• 1: A schematic representation of a housing part for a floor care device, in which a central ring line with 2 distribution points is inserted, from where the individual components are supplied,
• 2: the enlarged representation of a distribution point,
• 3: the enlarged representation of a distribution point with a directly connected component.

In Fig. 1, a housing of a floor care device is shown schematically, in which a motor-blower unit (10) with the motor (7a), as well as an on-off switch (7b) and a control lamp (7c) are integrated. The device includes an intake connector (11) and a blow-out connector (12), with an integrated but electrically separately insulated plug connection (13) for additional devices, not shown, being provided on the blow-out connector (12).
The electrical power supply now takes place via the handle (14) in which the supply line (15) is inserted is, on latching contacts (16), from where the ring supply line (4) starting over all multiple contact points (1) extends to the last contact point (here 13). At this multiple contact point (1), for the purpose of supplying energy to the various components (7a - 7c), tapping contacts (3) are inserted, which connect the looped supply lines (5), which are fixed in the insulating holders (17) by means of the cutting contacts (2), and thus enable one or more tapping connections (6) per tapping point (18).

Fig. 2 shows the detail from a multiple contact point (1), the cutting contacts (2) are pressed into insulating holders (17), in which the supply lines (5) are inserted and a tapping point (18) through the cutting contacts (2) form. Furthermore, a tapping contact (3) inserted into this insulating holder (17) is shown, from which the connecting line (6) leads to one of the components (7a - 7c).

Fig. 3 shows again a section of the multiple contact point (1) with the tapping contacts (3). The tapping contacts (3) are designed here as a pluggable component (8), and the tapping point (18) serves as a contact point for the directly pluggable component (8).

Claims (4)

1) Power supply for household appliances, in particular floor care devices, in which a central supply line supplies multiple contacts and from there supplies the individual electrical components individually, characterized in that the multiple contact point (1) consists of looped cutting contacts (2) with a plurality of central tapping contacts (3 ) is equipped. 2) Stromversorugng according to claim 1, characterized in that the multiple contact points (1) by means of a ring supply line (4) supplies all tapping contacts (3) electrically conductive. 3) Power supply according to claim 1 and 2, characterized in that both the supply lines (5) looped through the cutting contacts (2) and the connecting lines (6) starting from the tapping contacts (3) with the components to be supplied (7a - 7c) stay in contact. 4) Power supply according to claim 1 to claim 3, characterized in that the tapping contacts (3) plug-in components (8) are directly assigned.
