Electrical plug
First Claim
Patent Images
1. An electrical plug for connecting an electrical lead comprising a first conductor and a second conductor to an electrical power outlet, which plug comprises(A) a conductor-receiving member which comprises(1) a first channel in which the first conductor can be placed, and(2) a second channel in which the second conductor can be placed;
- and(B) a conductor-connecting member which comprises(1) a first contact member which comprises (a) a first prong suitable for insertion into one socket of the power outlet and (b) a first fuse-contact section,(2) a second contact member which comprises (a) a first conductor-contact section and (b) a second fuse-contact section,(3) a third contact member which comprises (a) a second conductor-contact section and (b) a second prong suitable for insertion into the other socket of the power outlet, and(4) a signal member which is connected between the second and third contact members and which provides a signal when current is passing therethrough;
the conductor-receiving member and the conductor-connecting member being(i) movable relative to each other between a unique mated configuration and a plurality of demated configurations;
(ii) such that in at least some of the demated configurations, the first conductor can be placed in the first channel and the second conductor can be placed in the second channel;
(iii) such that if the first conductor has been placed in the first channel and the second conductor has been placed in the second channel, the conductor-receiving member with the conductors placed therein and the conductor-connecting member can then be brought into the mated configuration, in which mated configuration the first conductor makes physical and electrical contact with the first conductor-contact section and the second conductor makes electrical contact with the second conductor-contact section; and
(iv) such that they cannot be brought into the mated configuration if the first conductor or the second conductor has been placed in direct physical contact with the respective conductor-contact section instead of being placed in the respective channel; and
(C) closure means for maintaining the conductor-receiving member and the conductor-connecting member in the mated configuration,whereby when the first and second prongs are inserted into the power outlet, the signal member provides a signal if a fuse connects the first and second fuse-contact sections and does not provide a signal if there is not electrical connection between the first and second fuse-contact sections.

Abstract
An electrical plug for connecting the first and second conductors of an electrical lead to an electrical power outlet. The plug is designed to contain a fuse. When the plug is connected to the power outlet and the fuse makes a proper electrical connection, a signal member provides a signal.
