Abstract

The hub of a vehicle steering wheel is provided with signaling contacts one of which is connected to a source of electric current through a connector which comprises an upwardly and downwardly movable conductor whose end remote from the contacts is anchored to a solid metal contact finger guided in an insulating sleeve. The insulating sleeve has a cylindrical portion in which the cylindrical shank of the contact finger is guided and defining a clearance around the shank open at an end of the sleeve to accommodate a coil spring which is seated against a shoulder of the sleeve and a head of the shank which bears against a slip ring. The other end of the contact finger, connected to the cable, is a solid body of square cross section guides in a corresponding square cross section passage of the insulating sleeve.

Claims

1. A steering wheel connector between a signaling contact arrangement and a slip ring, said connector comprising:

a cable connected at one end to said contact arrangement;

an insulating sleeve received in the hub of the steering wheel and having one end turned toward said contact arrangement, said sleeve formed with a throughgoing internal passage including a cylindrical portion opening at said one end of said sleeve, a rectangular cross section portion opening at said other end of said sleeve, and a peripheral shoulder between said portions and formed with a circular bore;

an upwardly and downwardly movable contact finger slidable in said sleeve, said contact finger having a cylindrical shank guided in said bore and extending through said cylindrical portion out of said sleeve at said other end of said sleeve and formed with a head, a rectangular-section body guide in said rectangular section portion and a connector sleeve formed on said body and secured to the other end of said cable within said insulating sleeve; and

a coil spring seated against said shoulder and bearing against said head while surrounding said shank in said cylindrical portion.

2. The connector defined in claim 1 wherein said body is of square section.

3. The connector defined in claim 2 wherein said contact finger is unitarily formed with said shank and said body has a solid metallic structure.

4. The connector defined in claim 3 wherein said head is threaded into said shank.

5. The connector defined in claim 4 wherein said connecting sleeve is formed unitarily on said body.

6. The connector defined in claim 5 wherein said connecting sleeve is crimped onto the said other end of said cable.
