[0001] The present invention relates to a contact board, the electrical household appliances is useful in particular for the power supply.

[0002] Thepinboards for orderly connecting the terminals of the wires of an electrical use of with the various lines of an electric household appliance supply cable , so as to supply it with current to ground is made, on the one hand, and, on the other hand, both the leads of the electric household appliance and preferably the body of the electric household appliance itself, the generally of metal, by means of the ground wire of the power supply cable. pinboards consist of a supporting body with the known To this end, various forms is made of an electrically insulating plastic material, and a plurality of metal terminals or bushings, are carried by the body, on the, often by means of jumpers, the various necessary electrical connections are made.

[0003] One problem of the present invention is, to eliminate the described disadvantages by providing a contact board, allowing it, the necessary electrical connections to a simple, rapid and reliable manner to produce, the the resulting improved and the electrical connections can be simply constructed and assembled in turn, has a small size and is reliable over time and the finally allows it, the ground connection of the body of the electric household appliance to facilitate.

[0004] the present invention relates to a contact board for electric household appliances according to claim, 1.

[0005] The contact board Points, in particular, a plate body, which is made from an electrically non-conductive material, a plurality of first blade contacts chamfering clay/tone -type the, which are carried by the plate body integrally on a first surface thereof, at least one end of an electrical cable to a ground connection and receptacle means, wherein said receiving means comprise integrally carried by the plate body at a first end thereof and optionally a cable clamping device are any known type.

[0006] in accordance with one feature of the invention is the ground connection on a first longitudinal side of the plate body in a position immediately adjacent the first end thereof and the receiving means of the end of the electrical cable are disposed on a second surface of the plate body opposite the first arranged in combination, on which further comprises first and second electrical wires of the electrical cable are arranged for respective terminals corresponding connecting bolt means , wherein the first connecting means for ground connection and the second connection means the receiving means of the end of the cable include facing relative to the first but at a second end of the plate body are disposed.

[0007], produced in accordance with a further feature of the invention, the first blade contacts chamfering clay/tone -type in a first group and a second group of the divided, which are provided respectively along the first side and a second longitudinal side of the plate body and are arranged in an adjacent position to the second end of the latter; each first and second group of said first blade contacts further integrally in one piece with a corresponding first and a second metal plate perpendicular to the same are obtained, wherein said first and second metal plates parallel to each other and adjacent the first or respectively of the second longitudinal side of the Austrian

Plate body are disposed, wherein they bear on the first surface thereof; the metal plates are connected directly to the second further connecting bolt means.

[0008] The latter comprise corresponding hexagon head screws, which with their heads within the corresponding seats of the plate body, which are provided on the second surface thereof, are arranged and so are used, so as to go through the plate body and through the corresponding ends of the first and the second metal plate;

wherein the corresponding nuts for the screws then be carried on the first surface of the panel body are held by the screws themselves and in use, wherein they are disposed against the metal plates butting attracted, on the side, which is turned in the direction of the metal plates, the nuts are preferably provided with corresponding knurls, are designed in use, so as to cut into itself in the metal plates.

[0009] So an optimum design is obtained the contact board, making it a user and/or operator (e.g. the person, allowing are assembled in the electronic household appliance), even in the presence of a rigid service cable all the necessary electrical connections to be made easily and quickly; actually the substantially rectilinear [...]neutral leader wires be held, while the ground wire (14) with a simple, short 90 °-curve is guided to the side, and so the preservation of a better is the magnification of the heads of the screws enables maneuvering area and, above all that is one of the first and second electrical connecting means, the further are hexagonal, to enable a firmer securing the wire connections and therefore a better electrical connection. Moreover, the particular arrangement of the electrical coupling means on one face and allow on the body of the contact board contacts on the opposite surface without the use of jumpers the obtaining of all necessary links. Lastly, the size, the cable clamping device, the is one of the receiving means for the electric wire, in comparison to that of the conventional pinboards be increased, so as to enable a more secure attachment. All while maintaining the dimensions of the current pinboards this can, be used for the same applications the, be achieved. Through the side assembly of the entire ground connection itself will also facilitate the ground connection of the body of the electric household appliance.

[0010] Further features and advantages of the present invention emerge from the following description of a non limiting embodiment thereof with reference to the Figures in the accompanying drawings shown; it show:
