Abstract
This invention involves an apparatus for terminating conduit, cable, and braided bundle in which the termination is accomplished with an interference fit between a collar and an end fitting. Once assembled, the conduit, cable, or braided bundle is compressed between the collar and the end fitting such that the final assembly can withstand the required level of axial and transverse force for the application, but not so much that the conduit, cable, or braided bundle loses its structural integrity.
Claims35
A conduit terminating apparatus comprising:
- a. An annular collar,
- (1) wherein said collar is open ended and defines an inner surface and an outer surface,
- (2) wherein said inner surface of said collar further defines an annular lip, an annular groove proximate to said lip, and an annular interior compression surface proximate to said annular groove,
- (3) wherein said collar is capable of being slid over the outer diameter of a conduit prior to assembling said conduit terminating apparatus,
- (4) wherein said lip has an inner diameter that is less than the inner diameter of said annular groove, and
- (5) wherein said annular groove has an inner diameter that is greater than the inner diameter of said annular compression surface;
- b. An end fitting,
- (1) wherein said end fitting is open ended and defines an inner surface and an outer surface;
- (2) wherein said outer surface of said end fitting defines an annular securing channel, an annular flange proximate to said securing channel, and an annular compression support region, and
- (3) wherein the outer diameter of said flange is greater than the outer diameter of said securing channel and said compression support region;
- and
- c. Wherein the relationship of the dimensions of said collar and said end fitting relative to each other and relative to the conduit is further defined as follows:
- (1) the outer diameter of said compression support region of said end fitting is less than the inner diameter of said interior compression surface of said collar, and the outer diameter of said compression support region of said end fitting added to twice the original thickness of the wall of the conduit is greater than the inner diameter of said interior compression surface of said collar,
- (2) the inner diameter of said lip of said collar is less than the outer diameter of said flange of said end fitting,
- (3) the inner diameter of said groove of said collar is greater than or equal to the outer diameter of said flange of said end fitting, and
- (4) wherein the outer diameter of said flange of said end fitting is greater than the inner diameter of said interior compression surface of said collar.
