DETAILED DESCRIPTION OF THE INVENTION

Firstly referring to FIG. 1 and FIG. 2, a cooling appliance 1 includes a cabinet 2 for defining at least one heat-insulated storage chamber (not shown) and a door 13 connected to a front end of the cabinet 2 to close the corresponding storage chamber. The cabinet 2 and the door 13 both have a heat-insulating layer (not shown), to reduce heat exchange of the interior of the storage chamber with the outside. The heat-insulating layer may be formed in a foaming process. The cabinet 2 and the door 13 together form a heat-insulating housing of the cooling appliance 1.
The door 13 is pivotally connected to the cabinet 2, and is rotatable about a longitudinal axis. An upper end of the door 13 is connected to the cabinet 2 through an upper hinge 14.
An end of the upper hinge 14 is connected in the door 13. Specifically, a hinge axial portion 27 of the upper hinge 14 is inserted into a hinge hole 26 on the door 13. The other end of the upper hinge 14 is plate-like, and is fixed on the cabinet 2.
The cabinet 2 is disposed with a recessed space 6 depressed from the housing on the top wall thereof. The recessed space 6 has an opening (not shown) facing the top side of the cabinet 2. The upper hinge 14 is fixed in the recessed space 6, and a front end thereof extends to the door 13.
The cooling appliance 1 includes a main control unit 22 located in the cabinet 2 and a displaying and/or operating unit 23 located in the door 13. The cooling appliance 1 further includes a transfer line connected between the main control unit 22 and the displaying and/or operating unit 23 to transfer power from the main control unit 22 to the displaying and/or operating unit 23 and transmit signals there-between.
The transfer line includes a cabinet-side cable 15 extending from the main control unit 22 into the recessed space 6 and a door-side cable 16 extending from the displaying and/or operating unit 23 into the recessed space 6. Ends of the cabinet-side cable 15 and the door-side cable 16 are respectively connected to a cabinet-side connector 17 and a door-side connector (not shown). The cabinet-side connector 17 and the door-side connector are connected in the recessed space 6 so as to make the cabinet-side cable 15 electrically connected to the door-side cable 16.
The cabinet-side connector 17 includes a connector housing 170 and several conductor terminals (not shown) fixed in the connector housing 170. The connector housing 170 has several terminal holes 171 to respectively accommodate a corresponding conductor terminal.
The conductor terminals are connected to the cabinet-side cable 15. Similarly, the door-side connector also has a connector housing and several conductor terminals connected to the door-side cable 16. Through connecting between the conductor terminals of the cabinet-side connector 17 and the door-side connector, the cabinet-side cable 15 is electrically connected to the door-side cable 16.
In this embodiment, two cabinet-side connectors 17 are provided, and correspondingly, two door-side connectors are provided. The two cabinet-side connectors 17 are arranged up and down, but have different transverse width and longitudinal height. It should be understood that, the number and specific construction of the electrical connector should not be limited in the present invention.
Referring to FIG. 2, the recessed space 6 includes a front portion 61 and a rear portion that is deeper than the front portion 61. The upper hinge 14 is accommodated in and is immovably fixed in the front portion 61.
The cabinet-side connector 17 and the door-side electrical connector are at least partially accommodated in the rear portion of the recessed space 6. According to a preferred embodiment of the present invention, the rear portion of the recessed space 6 is formed by a receiving member 3 fixed in the cabinet 2.
Referring to FIG. 2 to FIG. 4, the receiving member 3 is substantially box-like with an opening facing upwards. The receiving member 3 includes a base wall 31, a surrounding wall 32 connected to the base wall 31 and extending upwards, and a receiving space 33 enclosed by the base wall 31 and the surrounding wall 32. The receiving space 33 forms the rear portion of the recessed space 6.
The receiving member 3 includes a flange 35 bent outwards from the surrounding wall 32 and a groove 36 located on an upper end of the surrounding wall 32 and surrounding the receiving space 33. The receiving member 3 is connected to a housing 4 of the cabinet 2 before the foaming process of the cabinet 2 is implemented. Specifically, when the receiving member 3 is connected to the housing 4, the flange 35 is attached to an inner side of the housing 4, and the housing 4 has a connecting flange (not shown) inserted into the groove 36. After the foaming process is finished, the receiving member 3 is closely joined to the inner side of the housing 4 and the heat-insulating layer, and is embedded in the cabinet 2 in an undetachable manner.
The receiving member 3 has a pair of insertion holes 34 for communicating the interior of the receiving space 33 with the outside. The insertion holes 34 may be formed on the surrounding wall 32. It should be understood that, according to the design requirement, the insertion holes 34 may also be formed on the base wall 31.
Each cabinet-side connector 17 extends into the receiving space 33 from the receiving member 3 through the corresponding insertion hole 34. The insertion hole 34 penetrates the surrounding wall 32. In this embodiment, a part of the insertion hole 34 also protrudes outwards from an outer side of the surrounding wall 32, so that the length of the insertion hole 34 in an insertion direction is larger than the thickness of the surrounding wall 32.
According to the present invention, the cabinet-side connector 17 is fixed on the receiving member 3. A fixing mode between the cabinet-side connector 17 and the receiving member 3 according to a preferred embodiment of the present invention is illustrated in detail below.
The connector housing 170 of each cabinet-side connector 17 includes a pair of elastic pieces 172 connected to a corresponding side of a front end of the cabinet-side connector 17 (an end that contacts with the door-side connector) and extending backwards. The elastic piece 172 extends outwards from front to back, and has an inclined surface 173 that slants outwardly. A free end of the elastic piece 172 is bent inwards.
Each insertion hole 34 has a shape and a size substantially corresponding to an external contour of the cabinet-side connector 17. Specifically, the transverse dimension of the insertion hole 34 is set to enable the connector housing 170 to enter after the elastic pieces 172 are extruded inwards. After the elastic pieces 172 penetrate from the insertion hole 34, the distance between the ends of the pair of elastic pieces 172 that restore to their natural states is larger than the transverse dimension of the insertion hole 34, so that the elastic pieces can be butted against the inner side of the surrounding wall 32, to prevent the cabinet-side connector 17 from moving out of the insertion hole 34. The longitudinal dimension of the insertion hole 34 is slightly larger than that of the connector housing 170, so as to limit the movement of the connector housing 170 in the longitudinal direction.
The receiving member 3 includes a pair of stoppers 18 located opposite to each other in the receiving space 33. In an embodiment, the stopper 18 has a shape like a plate and is perpendicular to the insertion direction of the cabinet-side connector 17.
The distance between the stopper 18 and an inner end of the insertion hole 34 is smaller than the length of the connector housing 170. When the cabinet-side connector 17 extends into the receiving space 33, the front end of the connector housing 170 is abut against the stopper 18, so that the connector housing 170 is stopped from moving more further in the insertion direction. A part of the connector housing 170 is exposed in the receiving space 33, and the remaining part thereof is maintained in the insertion hole 34. Preferably, the rear end of the connector housing 170 does not exceed that of the insertion hole 34.
The stopper 18 presses against a side surface of the corresponding elastic piece 172, so that in the insertion direction of the cabinet-side connector 17, the stopper 18 is not overlapped with a mating surface 174 (in this embodiment, a front surface) of the connector housing 170 that contacts with the door-side connector.
The stopper 18 is pressed against the incline surface 173 of the elastic piece 172 that is inclined outwardly, which limits the movement of the connector housing 170 in the transverse direction and the insertion direction.
In an embodiment, the receiving member 3 stops the two cabinet-side connectors 17 from moving forwards or moving from left to right by using the pair of stoppers 18. Since the two cabinet-side connectors 17 have different width, the stoppers 18 are correspondingly step-like in a gap between the two cabinet-side connectors 17.
The cooling appliance 1 includes a hinge lid 8 for a user to close the recessed space 6. The hinge lid 8 extends from the cabinet 2 to above the door 13, so as to shield the upper hinge 14 and the receiving member 3.
According to the embodiment of the present invention, the cabinet-side connector 17 is fixed in the receiving member 3 through a fixing structure provided by the receiving member 3, so that the cabinet-side connector 17 is prevented from moving outside the receiving space 33 to cause damages during the foaming process of the cabinet 2.
In the above embodiment, the receiving member 3 is disposed near the upper hinge 14 to accommodate the cabinet-side connector 17 and the door-side connector. It should be understood that, the present invention should not be limited thereto, and other embodiments are also available. For example, the present invention is also applicable to an electrical connector for connecting at least two cables both located on the cabinet or door and a receiving member for accommodating such electrical connectors.
