Abstract
Abstract An electrical connector device for use in an electrical system requiring electrical connection between rotatable members. The device comprises a first insulator having at least one first terminal affixed thereto, a first shaft member projecting from the first insulator, a second insulator rotatably fitted over the first shaft member and having at least one second terminal affixed thereto, a second shaft member secured to the second insulator, a flexible conductor in the form of a wire having either end connected to the first and second terminals, the conductor being wound around the first shaft member, and a restriction mechanism for limiting relative rotation between the first and second insulators within a predetermined angle. The restriction mechanism includes a first gear of a relatively large diameter fitted over the first shaft member for angular movement therewith and a second gear of a relatively small diameter held in meshing engagement with the first gear for angular movement about the second shaft member. The first and second insulators can easily and precisely be positioned with respect to each other.

Claim 1
Independent Claim
166 words
An electrical connector device comprising: a first insulator having at least one first terminal affixed thereto; a first shaft member projecting from said first insulator; a second insulator rotatably fitted over said first shaft member and having at least one second terminal affixed thereto; a second shaft member secured to said second insulator; a flexible conductor in the form of a wire having one end thereof connected to said first terminal and the other end thereof connected to said second terminal, said conductor being wound around said first shaft member; and restriction means for limiting relative rotation between said first and second insulators within a predetermined angle, said restriction means including a first gear of a relatively large diameter fitted over said first shaft member for angular movement therewith and a second gear of a relatively small diameter held in meshing engagement with said first gear for angular movement about said second shaft member, one of said first and second gears including an enlarged gear tooth.
Claim 2
Dependent Claim
166 words
An electrical connector device comprising: a first insulator having at least one first terminal affixed thereto; a first shaft member projecting from said first insulator; a second insulator rotatably fitted over said first shaft member and having at least one second terminal affixed thereto; a second shaft member secured to said second insulator; a flexible conductor in the form of a wire having one end thereof connected to said first terminal and the other end thereof connected to said second terminal, said conductor being wound around said first shaft member; and restriction means for limiting relative rotation between said first and second insulators within a predetermined angle, said restriction means including a first gear of a relatively large diameter fitted over said first shaft member for angular movement therewith and a second gear of a relatively small diameter held in meshing engagement with said first gear for angular movement about said second shaft member, one of said first and second gears including an enlarged gear tooth.
Claim 3
Dependent Claim
87 words
An electrical connector device according to claim 1, wherein: said first gear comprises a spur gear having at least one first intertooth groove of a relatively large first pitch and a plurality of second intertooth grooves of a relatively small second pitch; and said second gear comprises a spur gear having said enlarged gear tooth provided thereon, said enlarged gear tooth comprising at least one first tooth of said first pitch, and said second spur gear also having at least one second tooth of said second pitch.
Claim 4
Dependent Claim
22 words
An electrical connector device according to claim 2, wherein: said first pitch is substantially three times as large as said second pitch.
Claim 5
Dependent Claim
29 words
An electrical connector device according to claim 3, wherein: said first gear has a plurality of said first intertooth grooves; and said second gear has one said first tooth.
Claim 6
Dependent Claim
146 words
An electrical connector device comprising: a first insulator having at least one first terminal affixed thereto; a first shaft member projecting from said first insulator; a second insulator rotatably fitted over said first shaft member and having at least one second terminal affixed thereto; a second shaft member secured to said second insulator; a flexible conductor in the form of a wire having one end thereof connected to said first terminal and the other end thereof connected to said second terminal, said conductor being wound around said first shaft member; a first gear of a relatively large diameter fitted over said first shaft member for angular movement therewith; a second gear of a relatively small diameter held in meshing engagement with said first gear for angular movement about said second shaft member; and a marking for positioning said first and second gears relative to each other.
Claim 7
Dependent Claim
146 words
