Safety connector for household table-top electrical appliances
First Claim
1. - A safety connector for a household table-top electrical appliance, constituted by an ensemble formed by two parts, one of which is fixed and constitutes a socket member (3) mounted in the appliance, and the other is removable and constitutes a plug member (2) mating with said socket member, said plug member (2) forming a terminal for an end of a flexible power cord (5), said power cord (5) having at the other end thereof a plug member which may be plugged into an electric mains socket member, there being provided magnetic means allowing a stable mechanical and electrical connection of both parts to be maintained and allowing the mechanical and electrical disconnection of said two parts under an abnormal strain exerted on the plug member (2), wherein the socket member (3) comprises pins (14), associated with the electrical load bearing members of the appliance, and a grounding arrangement (20), there being situated between said pins (14) and said grounding arrangement (20) a magnet arrangement (15) and two active armatures (16), while the plug member (2) comprises two resiliently flexible electrical contacts (7) spatially mating with the pins (14) of said socket member (3), there being situated between said electrical contacts (7) an iron plate member (11) as passive armature which, in the plugging in operation, is in facing alignment with the active armatures (16) of the magnet (15) and in contact with the ground (20).

Abstract
A safety connector for a table-top household electrical appliance, formed by a socket member (3) mounted in the appliance and a plug member (2) complementary to the socket member (3), and having magnets that allow a plugged-in position to be maintained and separation of both parts under an abnormal strain exerted on the plug member. The socket member (3) comprises pins (14) and a grounding arrangement (20), with a magnet arrangement (15) and two active armatures (16) between them. The plug member (2) comprises two flexible electrical contacts (7), spatially mating with the pins (14). An iron plate member (11) as passive armature is located between the electrical contacts (7) and when making connection, it faces the active armatures (16) of the magnet (15) and makes contact with the ground (20).
