Protection shield positioning assembly and positioning device therefor and method of use
A method and assembly for protecting a device connected to a wiring harness is disclosed. The assembly includes a protective shield having a bore for receiving the device and a positioning device. An elongated wiring harness extends from the device being protected and through the bore of the protective shield. The positioning device is formed having a band that surrounds a central space. At least one flexible, resilient finger extends radially inwardly from the band into the central space. At least one of the fingers forcibly engages the harness sleeve to maintain the positioning device and the protective shield in a predetermined protection position along the harness sleeve at least partially surrounding the device being protected.
1. In combination, a positioning device and an elongated member, said positioning device comprising:
a band surrounding a central space;
at least one flexible, resilient finger having a first end attached to said band and a second end extending radially inwardly toward said central space, at least one of said second end being engageable with said elongated member received within said central space, said band and said at least one finger being slidably movable along said elongated member to a predetermined position upon the application of a force to said band directed along a longitudinal axis of said elongated member and sufficient to overcome resistance between said at least one finger and said elongated member, at least one of said second end forcibly engaging said elongated member and holding said band in said predetermined position in the absence of said force and maintaining said band in said predetermined position along said elongated member, and
wherein said elongated member comprises a plurality of annular corrugations spaced axially from one another by annular channels wherein at least one of said second end is received within one of said annular channels between adjacent corrugations to maintain said band in said predetermined position, said at least one finger being resiliently flexible and passing over said corrugations upon application of a force to said band along said central axis to allow said positioning device to move axially relative to said elongated member, and
wherein said position device has a plurality of said fingers with adjacent ones of said fingers having different radially extending lengths.
2. The combination of claim 1 wherein every other finger is the same length.
3. The combination of claim 1 wherein said positioning device has a plurality of said fingers with at least some of said second ends remaining spaced radially outwardly from said elongated member.
4. The combination of claim 1 wherein said band has a circular perimeter.
5. The combination of claim 1 wherein said band is elongated along said axis.
6. The combination of claim 5 wherein said band is sized for at least partial receipt within said bore of a sleeve.
7. The combination of claim 5 wherein said band is conically tapered.
8. The combination of claim 6 further comprising a rim attached to said band and extending radially outwardly therefrom, said rim being engageable with said sleeve.
9. The combination of claim 8 wherein said rim is attached at one end of said band.
10. The combination of claim 9 wherein said at least one finger is positioned at an end of said band opposite said rim.
11. The combination of claim 9 wherein said at least one finger is positioned at said one end of said band.
12. The combination of claim 1 wherein said at least one finger is wedge shaped, said first end being wider than said second end.
13. The combination of claim 1 wherein a plurality of slits having a generally uniform width are defined between said fingers.
14. The combination of claim 1 wherein spaces are defined between adjacent ones of said fingers.
15. The combination of claim 14 wherein said spaces are shaped the same as said fingers.
16. The combination of claim 1 wherein said second end has a shape complementary to an outer surface of said elongated member.
17. The combination of claim 16 where said shape defines a concave surface.
18. The combination of claim 17 wherein said concave surface defines a circular arc about said axis.
19. The combination of claim 1 wherein said positioning device has a protective sleeve formed as one piece of material therewith, said protective sleeve having an inner dampening layer.
20. The combination of claim 1 wherein said positioning device has at least a pair of fingers extending toward separate axes to form at least in part a pair of separate openings for receiving a pair of said second elongated members.
21. The combination of claim 20 further comprising a plurality of fingers extending toward one of said axes and a plurality of fingers extending toward the other of said axes.
