Abstract
Abstract A two-piece electrical disconnect means which can be assembled or disconnected in an in-line connection or from two directions 90* apart, or from any angle in between. A female plug has a molded insulating body which carries a plurality of receptacle type female terminals which are each open on the outer end and on one side thereof for the reception of a spade type male terminal, at any angular position between and including an in-line position and a right-angle position. A male plug has a molded insulating body which carries a plurality of spade type male terminals which are adapted to be received in the female receptacle terminals.

Claim 1
Independent Claim
371 words
An electrical disconnect means comprising: a. a male plug having an insulating body which carries a plurality of spade type male terminals and with each male terminal electrically connected to a lead wire; b. a female plug having an insUlating body which carries a plurality of receptacle type female terminals which are each open on the outer end and one side thereof for the reception of a spade type male terminal at any angular position between an in-line connection with the male terminal inserted into the open outer end of the female terminal and a right-angle connection with the male terminal inserted into the open side of the female terminal, and with each female terminal electrically connected to a lead wire; c. said female plug body having a flat outer end perpendicular to the longitudinal axis thereof through which is accessible the open end of each of the receptacle type female terminals; d. said female plug body having a flat longitudinally extended surface on said one side thereof through which is accessible the open side of each of the receptacle type female terminals; e. said male plug body having a flat outer end perpendicular to the longitudinal axis thereof with the spade type male terminals extended outward therefrom; and, f. said male plug body having a longitudinal extension on one side of said outer end and which is provided with a flat inner face perpendicular to said flat outer end, whereby when the male plug is connected to the female plug in an in-line connection the flat outer end on the female plug body is seated against the flat outer end on the male plug body and the flat longitudinally extended surface on one side of the female plug body is seated against the flat inner face on the longitudinal extension on the male plug body, and when the female plug is attached to the male plug in a right angle connection, the flat outer end on the female plug body seats on the flat inner face on the longitudinal extension on the male plug body and the flat outer end on the male plug body seats against the longitudinally extended flat surface on one side of the female plug body.
Claim 2
Dependent Claim
371 words
An electrical disconnect means comprising: a. a male plug having an insulating body which carries a plurality of spade type male terminals and with each male terminal electrically connected to a lead wire; b. a female plug having an insUlating body which carries a plurality of receptacle type female terminals which are each open on the outer end and one side thereof for the reception of a spade type male terminal at any angular position between an in-line connection with the male terminal inserted into the open outer end of the female terminal and a right-angle connection with the male terminal inserted into the open side of the female terminal, and with each female terminal electrically connected to a lead wire; c. said female plug body having a flat outer end perpendicular to the longitudinal axis thereof through which is accessible the open end of each of the receptacle type female terminals; d. said female plug body having a flat longitudinally extended surface on said one side thereof through which is accessible the open side of each of the receptacle type female terminals; e. said male plug body having a flat outer end perpendicular to the longitudinal axis thereof with the spade type male terminals extended outward therefrom; and, f. said male plug body having a longitudinal extension on one side of said outer end and which is provided with a flat inner face perpendicular to said flat outer end, whereby when the male plug is connected to the female plug in an in-line connection the flat outer end on the female plug body is seated against the flat outer end on the male plug body and the flat longitudinally extended surface on one side of the female plug body is seated against the flat inner face on the longitudinal extension on the male plug body, and when the female plug is attached to the male plug in a right angle connection, the flat outer end on the female plug body seats on the flat inner face on the longitudinal extension on the male plug body and the flat outer end on the male plug body seats against the longitudinally extended flat surface on one side of the female plug body.
Claim 3
Dependent Claim
32 words
An electrical disconnect means as defined in claim 1, wherein: a. each of said male and female plug bodies is molded to the lead wires electrically attached to the terminals carried therein.
Claim 4
Dependent Claim
35 words
An electrical disconnect means as defined in claim 2, wherein: a. one of said plurality of female terminals is a ground terminal; and, b. one of said plurality of male terminals is a ground terminal.
Claim 5
Dependent Claim
86 words
An electrical disconnect means as defined in claim 3, wherein: a. the ground female terminal is located closer to the flat outer end and the flat longitudinally extended surface than are the other female terminals so that the male ground terminal will contact the female ground terminal before the other male and female terminals contact during a connection operation, and the male ground terminal will break last from the female terminal when the other male and female terminals break from each other during a disconnection operation.
Claim 6
Dependent Claim
39 words
An electrical disconnect means as defined in claim 3, wherein: a. the contact area between a female terminal and a male terminal is essentially the same when they are connected in an in-line connection and in a right-angle connection.
