Abstract

A process for manufacturing a rotary connector device for making a plurality of electrical connections includes construction of a male connector component and a female conductor component. The male connector component is constructed by providing a male underlying body having a plurality of longitudinal channels formed therein for holding male conducting wires. Alternating separate male conducting rings and separate male insulating rings are placed on the underlying body with each separate conducting wire occupying a separate channel. The female conductor component is constructed by providing a female body with a central bore having at least one groove formed therein for holding female conducting wires. Separate alternating female conducting rings and separate female insulating rings are installed on a rod and transferred to the central bore of the female body with the female conducting wires occupying the groove.

Claims

1. A process for manufacturing a rotary connector device for making a plurality of electrical connections in a mating arrangement between two components, the method comprising separately constructing a male connector component and a female conductor component,

wherein the male connector component is constructed by:

a) providing a male underlying body for holding a series of separate alternating separate male conducting rings and separate male insulating rings, the underlying body having a plurality of longitudinal channels formed therein for holding male conducting wires; and

b) connecting a separate conducting wire to each separate male conducting ring and placing the alternating separate male conducting rings and separate male insulating rings on the underlying body with each separate conducting wire occupying a separate one of the plurality of longitudinal channels to extend through to the rearward end of the male component and fixing the alternating separate male conducting rings and separate male insulating rings in place on the underlying body with a male end part;

and wherein the female conductor component is constructed by;

a) providing a female body with a central bore configured to retain a series of separate alternating female conducting rings and separate female insulating rings, the central bore having at least one groove formed therein for holding female conducting wires; and

b) installing the separate alternating female conducting rings and separate female insulating rings on a rod and transferring the separate alternating female conducting rings and separate female insulating rings to the central bore of the female body with the female conducting wires occupying the at least one groove and fixing the separate alternating female conducting rings and separate female insulating rings in place within the central bore with a female end part.

2. The process of claim 1, wherein the male conducting wires are connected to a male feed-through connector at the back end of the male underlying body.

3. The process of claim 1, wherein the female conducting wires are connected to a female feed-through connector at the back end of the female body.

4. The process of claim 1, wherein the separate male conducting rings each have a groove in an inner sidewall and the step of connecting each separate male conducting wire to each separate male conducting ring is performed by connecting each separate male conducting wire to the groove in the inner sidewall of a corresponding separate male conducting ring.

5. The process of claim 1, wherein each female conducting ring has an outer groove in an outer sidewall and the step of connecting each separate female conducting wire to each separate female conducting ring is performed by connecting each separate female conducting wire to the groove in the outer sidewall of each separate male conducting ring.

6. The process of claim 1, further comprising the step of placing a pourable adhesive into the longitudinal channels of the male underlying body to further fix the male conducting wires and separate male conducting rings and separate male insulating rings in place.

7. The process of claim 1, further comprising the step of placing a pourable adhesive into the at least one groove of the female body to further fix the female conducting wires and separate female conducting rings and separate female insulating rings in place.

8. The process of claim 1, wherein the male end part is a conducting extension which is fixed to the male underlying body with a separate fastener.

9. The process of claim 1, wherein the female end part is an insulating ring which is threaded onto the female body.

10. The process of claim 1, wherein the male conducting rings and the female conducting rings, or separate conducting components associated therewith, have contact surfaces with complementary shapes that engage each other in a latching mechanism when the mating arrangement is made.

11. The process of claim 10, wherein the complementary shapes of the male conducting rings and the female conducting rings are provided by indentations in the male conducting rings and protrusions in the female conducting rings which are substantially complementary in shape to the indentations.

12. The process of claim 10, wherein the separate conducting components of the female conducting rings are conducting springs held within openings with circumferential cavities in the female conducting rings.

13. The process of claim 12, wherein the conducting springs are canted coil springs.

14. The process of claim 12, wherein the circumferential cavities are each defined by a five-sided polygonal inner sidewall defined by two opposed vertical walls connected to a horizontal floor by two angled walls.

15. The process of claim 12, wherein the male conducting rings each have circumferential indentations and the conducting springs provide convex surfaces complementary to the indentations of the male conducting rings, wherein mating of the convex surfaces to the indentations provides a compression force for the latching mechanism.

16. The process of claim 1, wherein the central bore is non-circular and the female conducting rings and female insulating rings are non-circular.

17. The process of claim 16, wherein the central bore is stadium-shaped and the female conducting rings and female insulating rings are stadium-shaped.

18. The process of claim 8, wherein the conducting extension has a frustoconical head portion and an indentation for conductively latching to a corresponding female conducting ring.

19. The process of claim 1, wherein the plurality of electrical connections is 10 separate electrical connections which are made via a combination of 9 male conducting rings and the conducting extension with 10 corresponding female conducting rings.

20. The process of claim 1, wherein the male underlying body, the male insulating rings, the female body and the female insulating rings are formed by injection molding and/or 3-D printing.
