All directional references such as front, left or bottom are based on reference to the domestic appliance (1 ) shown in Figure-1 , in which the visible side in x direction is the "left" side of the domestic appliance (1 ), the visible side in y direction is the "rear" side of the domestic appliance (1 ), and the visible side in z direction is the "bottom" side of the domestic appliance (1 ). One or more of possible embodiments of the present invention will be described as examples in detail below.

In figure-1 , a refrigerator, a possible domestic appliance (1 ), is presented. The domestic appliance (1 ) has a cooling chamber (14) defined by a body (10) and a door (2) pivotably connected to the body (10). Under the body (10), a machine chamber (15) is defined. The machine chamber (15) is a chamber where components of a cooling circuit are accommodated. The domestic appliance (1 ) has a mains connection (300) on an outer face (11 ) thereof. The outer face (1 1 ) is a front face of the machine chamber (15) in figure-1. In figure-2, the machine chamber (15) is represented as a schematic drawing. In which, a compressor (16) and a condenser (17) is illustrated. In the domestic appliance (1 ), the evaporator of the cooling circuit exists behind an evaporator cover (40) shown in figure-1. The pipe connections of the components of the cooling circuit are not shown in the figure-2. The machine chamber (15) also contains a electronic unit (20) that is inaccessible from outside of the domestic appliance (1 ). The electronic unit (20) is connected to other electrical, electronic and/or electro-mechanic elements by a cable or cables (21 ) like a cable harness. The electronic unit (20) controls the cooling process of the domestic appliance (1 ). It may also control different features of the domestic appliance (1 ) like illumination, heating (frame heating etc.).

Electric energy needed by the electronic unit (20) and the domestic appliance (1 ) is provided by the mains connection (300) from a domestic mains power supply being usually an electric plug of a house. It may also be a generator or any other electric source known in the art. When needed, for example for re-programming, fixing, diagnostic of a problem, controlling the appliance by a mobile application through internet/local network etc., domestic user or especially a competent user to perform such processes, like a serviceman or a repairman, should reach the electronic unit (20) electronically. The competent user should contact to the electronic unit (20) directly and connect his necessary electronic devices (computer etc.) to the electronic unit (20). For facilitating this process, a connection device (30) is used to reach the electronic unit (20) from outside of the domestic appliance (1 ) for performing such electronic processes.

The domestic appliance (1 ) has a connection cable (18) that has more than one connection terminals at the first end (180) and one connection plug (182) at the second end (181 ). The connection plug (182) on the second end (181 ) is capable to connect and transfer both mains power and data. One of the connection terminals on the first end (180) is used to connect to the domestic mains power supply. The other one of the connection terminals on the first end (180) may be connectable to the competent user's electronic devices and/or may be connectable to a modem (19) as represented in figure- 2.

The modem may be a wired or a wireless modem so that the competent user may connect to the electronic unit (20) without being close to the domestic appliance (1 ) and perform necessary processes like diagnostic and/or fixing/repairing.

The data and mains power connection between the connection device (30) and the electronic unit (20) is provided by a transferring element (50), which is one or more cable. In the possible embodiment of the invention, the transferring element (50) is provided as one for mains power transfer and one for data transfer. For easy understanding, the transferring element (50) is presented as one in figure-2. It may also be a single cable having more than one line in it for mains power and data. The connection device (30) basically has a mains connection (300) and a circuit board (330) without any electronic component except traces (341 ). The mains connection (300) is a plastic socket. It may be obtained from any nonconductor material known in the art as a material used for an electric socket. The mains connection (300) is fixed to the board (330) by two protrusions (303) on the mains connection (300) and two corresponding connection openings (343) on the board (330). The protrusions (303) are formed integrally on a bottom face (302) of the mains connection (300) that faces the board (330). That means the protrusions (303) are also plastic or made from a nonconductive material. The protrusions (303), and thus the mains connection (300), is fixed to the board (330) by force-fit. However, the protrusions (303) or the mains connection (300) itself may be glued to the board (330) by using compatible adhesives known in the art. On the other hand, fixations by form-fit solutions may also be used to secure the mains connection (300) on the board (330).

The mains connection (300) has three conductive blades (320) for line, neutral and earth of the mains power supply. The blades (320) are accessible from a front opening of the socket- type mains connection (300). The blades (320) penetrate into housings provided on the connection plug (182) connected to the mains connection (300). The mains connection (300) also has two facing tabs (421 ) to secure the connection plug (182) inside the mains connection (300).

The each one of blades (320) also have two extensions (321 ) to be soldered to the board (330). The extensions (321 ), similar to the protrusions (303), extends from the bottom face (302) of the mains connection (300). The board (330) has corresponding traces (341 ) for each of line, neutral and earth blades (320). By soldering, the blades (320) are conductively connected to the board (330).

On an inner face (310) of the mains connection (300), particularly bottom inner face (310), there is an opening (311 ). When the mains connection (300) is fixed to the board (330), a section of the board (330) disposed just next to the opening (31 1 ) as forming the missing inner face (310) of the mains connection (300) due to the opening (31 1 ). On the stated section of the board (330), there are three data transmission contacts (340). As a result, as in figure-9, the data transmission contacts (340) are accessible through the opening (311 ), and thus through the mains connection (300). The connection plug (182) contains corresponding data transmission contacts (not shown in figures) and these contact to the data transmission contacts (340) on the board (330). The data transmission contacts (340) are provided on traces (341 ) of the board (330) that are traces (341 ) other than the traces (341 ) for the blades (320). The board (330) remains almost parallel to the bottom face (302) of the mains connection (300), when the mains connection (300) is secured to the board (330). As a result, a front face (301 ) of the mains connection (300) rises vertically above a front edge (331 ) of the board (330). On a section close to a rear edge (332) of the board (330), the board (330) has trace ends (342) as exemplified in figure-3. There are six trace ends (342). Three of them are connected to the blades (320) by the corresponding traces (341 ). The remaining three of them are connected to the data transmission contacts (340) by the corresponding traces (341 ). These trace ends (342) are used to connect the transferring element (50) to the connection device (30). The connection may be realized by using cable terminals known in the art. The rear edge (332) has slits (333) between at least two trace ends (342) of each group of three trace ends (342) to prevent wrong connection of the cable terminals.

For fastening the connection device (30), a fastening device (60) is provided as shown in a perspective view in figure-4 as embodiment. In figure-4, a view of an inner face (13) of the body (10), which thus faces the interior of the domestic appliance (1 ), is shown. The fastening device (60) is formed directly at a hole (12) on the outer face (1 1 ) and comprises two opposing rails (61 ) to guide and retain the connection device (30). The rails (61 ) are formed at opposing edges, which delimit the hole (12). The rails (61 ) are formed in one piece from the inner face (13) and formed accordingly. They are both rectilinear and comprise side walls (62) raised above or protruding from the plane of the inner face (13) and thus from the plane of the hole (12).

In the present case the side walls (62) extend as it were into the interior.

On the sides of these side walls (62), which face away from the hole (12), top walls (63) are formed, which are oriented at an angle, in particular between 80° and 100°, preferably 90°, towards the side walls (62). The two rails (61 ) are thus L-shaped as it were, when viewed in cross section.

Moreover it is to be seen that only one of the two rails (61 ) has a stop ridge (64), which is formed on the top wall (63). The stop ridge (64) is arranged at one end of the top wall (63) and extends perpendicularly to the longitudinal direction A of the rail (61 ) and thus of the top wall (63) in the direction of the opposite top wall (63). By means of this stop ridge (64), which extends in the plane of the top wall (63) and is formed plate-like, an assembly coding is generated. This means that the connection device (30) can be positioned and fixed between the rails (61 ) only in a certain position. Incorrect mounting is thus prevented. The fastening device (60) moreover comprises two fixing elements (65) formed and arranged separately from the rails (61 ). The fixing elements (65) are formed at opposing edges other than ones where the rails (61 ) exist. The fixing elements (65) are plate-like tabs, which are oriented at an angle and thus likewise protrude from the plane of the inner face (13) and thus of the hole (12).

The board (330) having the mains connection (300) thereon is disposed on the inner face (13) of the body (10) as represented in figure-5 by the fastening device (60).

The connection device (30) has a cover (40) to protect the board (330) and the mains connection (300) inside the body (10) against water possibly existing in the domestic appliance (1 ) like a dishwasher, a refrigerator or a washing machine etc. The cover (40) of the embodiment is presented in figure-6. The cover (40) is made of plastic or plastic based material. The cover (40) has a wide section (400) for the board (330) and a narrow upper section (440) for the mains connection (300). It has a front opening (450) to allow penetration of the board (330) and the mains connection (300) inside the cover (40). On the inner side walls (401 ) of the wide section (400), it has guides (410) to slide the board (330) into the cover (40). At the rear end of the each guide (410), the cover (40) has a latching element (420).

The latching element (420) is formed by creating cut between side wall of the wide section (400) of the cover (40) and the wide section (400) of the cover (40). As a result, the latching element (420) has a plate forming the side wall of the wide section (400) connected to the cover (40) integrally only by its front edge. Therefore, the plate may be bended or spring around an axis provided by the front edge of the plate. The latching element (420) also has a tab (421 ) for latching the cover (40) on the board (330). Corresponding to that, the board (330) has a recess (335) at each of rear section of its side edges (334). The recess (335) is substantially in form of a rectangle. The tab (421 ) of the cover (40) has substantially a form of a right triangle or a right trapezium in a sectional view (Figure-7). As a result, the tab (421 ) has a locking wall (422) vertical to the plate of the latching element (420) to contact a wall of the recess (335) and prevent the cover (40) from leaving the board (330).

On the rear wall (430) of the cover (40), there are two terminal openings (431 ) corresponding to the trace ends (342) at the rear edge (332) of the board (330). One of the terminal openings (431 ) is for data transmission and the other one of the terminal openings (431 ) is for mains power transmission. The one group of three trace ends (342) is accessible through one terminal opening (431 ). The other one group of three trace ends (342) are accessible through other terminal opening (431 ). On the bottom edge of the each terminal opening

(431 ) , there is a platform (432) integrally formed on the same plane of bottom wall of the wide section (400). The platform (432) is in form of a rectangle plate. On vicinity of the rear edge of the each platform (432), there is a retainer (433) on the upper face of the platform

(432) . The retainer (433) is used to retain a cable terminal of the transferring element (50) on the platform (432), thus on the cover (40). The retainer (433) has substantially a right triangle form in sectional view. The right edge of the right triangle faces the terminal opening (431 ). When the connection device (30) is wanted to be mounted on the domestic appliance (1 ), the board (330) having the mains connection (300) thereon is slid on the inner wall (13) and secured on the fastening device (60). After that, the cover (40) is pushed by sliding it on the board (330) by locating the edges of the board (330) inside the guides (410) of the cover (40). The board (330) and the mains connection (300) are got into the cover (40) through the front opening (450) of the cover (40). During the slide of the cover (40), the latching element (420) is bent away from the wide section (400). When the tab (421 ) of the latching element (420) is arrived to the recess (335) on the board (330), the tab (421 ) goes into the recess (335) and locks the cover (40) on the board (330). Lastly, the cable terminals of the transferring element (50) are connected to the board (330) through the terminal openings (431 ). As a result, connection between the electronic unit (20) and the connection device (30) is realized.
