Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 140 words
A central unit for grouping electronic and electrical components of a refrigerator or freezer, including: a housing, at least one electronic circuit board mounted in said housing and including electrical connection means accessible through a closable opening in said housing for connecting at least one cable and plug for powering an electrical component of said refrigerator or freezer, a cover for said closable opening having passageways corresponding in number to the number of cable and plugs to be connected to said electronic circuit board, and a socket on said housing for connection of said appliance to an electric power source wherein hook-shaped appendices are provided adjacent said socket to engage an angle plug and thereby retain said angle plug in said socket but not engage a straight plug in said socket and thereby allow free engagement/disengagement of a straight plug.
Claim 2
Dependent Claim 140 words
A central unit for grouping electronic and electrical components of a refrigerator or freezer, including: a housing, at least one electronic circuit board mounted in said housing and including electrical connection means accessible through a closable opening in said housing for connecting at least one cable and plug for powering an electrical component of said refrigerator or freezer, a cover for said closable opening having passageways corresponding in number to the number of cable and plugs to be connected to said electronic circuit board, and a socket on said housing for connection of said appliance to an electric power source wherein hook-shaped appendices are provided adjacent said socket to engage an angle plug and thereby retain said angle plug in said socket but not engage a straight plug in said socket and thereby allow free engagement/disengagement of a straight plug.
Claim 3
Dependent Claim 25 words
A central unit as claimed in claim 1 , wherein the housing includes a second socket for connection of a capacitor to said circuit board.
Claim 4
Dependent Claim 37 words
A central unit as claimed in claim 2 , wherein said second socket includes slots for the capacitor electrical connection blades, which are closed by a thin wall breakable on engagement by said capacitor electrical connection blades.
Claim 5
Dependent Claim 150 words
A central unit for grouping electronic and electrical components of a refrigerator or freezer, including: a housing, at least one electronic circuit board mounted in said housing and including electrical connection means accessible through a closable opening in said housing for connecting at least one cable and plug for powering an electrical component of said refrigerator or freezer, a cover for said closable opening having passageways corresponding in number to the number of cable and plugs to be connected to said electronic circuit board, a first socket on said housing for connection of said appliance to an electric power source including hook-shaped appendices adjacent said first socket and arranged to engage an angle plug to retain said angle plug in said first socket but allow free engagement/disengagement of a straight plug in said socket, and a second socket on said housing for connection of a capacitor to said circuit board.
Claim 6
Dependent Claim 150 words
A central unit for grouping electronic and electrical components of a refrigerator or freezer, including: a housing, at least one electronic circuit board mounted in said housing and including electrical connection means accessible through a closable opening in said housing for connecting at least one cable and plug for powering an electrical component of said refrigerator or freezer, a cover for said closable opening having passageways corresponding in number to the number of cable and plugs to be connected to said electronic circuit board, a first socket on said housing for connection of said appliance to an electric power source including hook-shaped appendices adjacent said first socket and arranged to engage an angle plug to retain said angle plug in said first socket but allow free engagement/disengagement of a straight plug in said socket, and a second socket on said housing for connection of a capacitor to said circuit board.
Claim 7
Dependent Claim 36 words
A central unit as claimed in claim 4 wherein said second socket includes slots for capacitor electrical connection blades, said slots being closed by a thin wall breakable on engagement by said capacitor electrical connection blades.
Claim 8
Dependent Claim 174 words
A central unit for grouping electronic and electrical components of a refrigerator or freezer, including: a housing, at least one electronic circuit board mounted in said housing and including electrical connection means accessible through a closable opening in said housing for connecting at least one cable and plug for powering an electrical component of said refrigerator or freezer, a cover for said closable opening having passageways corresponding in number to the number of cable and plugs to be connected to said electronic circuit board, a first socket on said housing for connection of said appliance to an electric power source including hook-shaped appendices adjacent said first socket and arranged to engage an angle plug to retain said angle plug in said first socket but allow free engagement/disengagement of a straight plug in said first socket, a second socket on said housing for connection of a capacitor to said circuit board including slots for capacitor electrical connection blades, said slots being closed by a thin wall breakable on engagement by said capacitor electrical connection blades.
Claim 9
Dependent Claim 174 words
A central unit for grouping electronic and electrical components of a refrigerator or freezer, including: a housing, at least one electronic circuit board mounted in said housing and including electrical connection means accessible through a closable opening in said housing for connecting at least one cable and plug for powering an electrical component of said refrigerator or freezer, a cover for said closable opening having passageways corresponding in number to the number of cable and plugs to be connected to said electronic circuit board, a first socket on said housing for connection of said appliance to an electric power source including hook-shaped appendices adjacent said first socket and arranged to engage an angle plug to retain said angle plug in said first socket but allow free engagement/disengagement of a straight plug in said first socket, a second socket on said housing for connection of a capacitor to said circuit board including slots for capacitor electrical connection blades, said slots being closed by a thin wall breakable on engagement by said capacitor electrical connection blades.
