Abstract

A cable assembly includes coaxially arranged inner and outer barrels. The outer barrel overlaps a portion of the inner barrel. The inner and outer barrels respectively include first and second features that cooperate with one another to form a retention feature. The cable assembly has a cable that has at least one wire surrounded by an inner insulator that is covered in a metallic shield. The metallic shield is arranged in between the inner and outer barrels. The first feature is arranged beneath the metallic shield, and the second feature is arranged over the metallic shield. At least one of the first and second features extends in a radial direction relative to the other of the first and second features to capture the metallic shield with the retention feature.

First claim

What is claimed is:

1. A cable assembly comprising:
coaxially arranged inner and outer barrels, the outer barrel overlaps a portion of the inner barrel, the inner and outer barrels respectively include first and second features that cooperate with one another to form a retention feature;
a cable including at least one wire surrounded by an inner insulator covered in a metallic shield, wherein the metallic shield is arranged in between the inner and outer barrels;
wherein the first feature is arranged beneath the metallic shield, and the second feature is arranged over the metallic shield, at least one of the first and second features extends in a radial direction relative to the other of the first and second features to capture the metallic shield with the retention feature; and
wherein the first features is provided by a window, and the second feature is provided by a depression extending radially inward to the window, a portion of the depression provides a sheared edge.

2. The cable assembly of claim 1 , wherein the metallic shield is provided by a braided or foil sleeve, wherein one of the inner and outer barrels is secured to an electrical connector having an outer housing, and the metallic shield is grounded and secured to the outer housing, wherein the metallic shield is covered in a nonconductive sheathing, and the other of the inner and outer barrels is secured over the nonconductive sheathing.

3. The cable assembly of claim 1 , wherein the outer barrel includes a crimped portion provided by a plastically deformed area and that generates a clamping force on the metallic shield and the inner barrel.

4. The cable assembly of claim 1 , wherein the sheared edge is arranged inboard from a perimeter of an outer barrel blank.

5. The cable assembly of claim 1 , wherein the sheared edge is provided between opposing sides of the portion of the depression, wherein both of the opposing sides extend radially into the window.

6. The cable assembly of claim 1 , wherein the inner and outer barrels are each metallic cylindrically-shaped or oval shaped members.

7. The cable assembly of claim 1 , wherein the inner and outer barrels are formed from sheet metal blanks, at least one of the first and second features are provided in the blanks.

8. A cable assembly comprising:
coaxially arranged inner and outer barrels, the outer barrel overlaps a portion of the inner barrel, the inner and outer barrels respectively include first and second features that cooperate with one another to form a retention feature;
a cable including at least one wire surrounded by an inner insulator covered in a metallic shield, wherein the metallic shield is arranged in between the inner and outer barrels;
wherein the first feature is arranged beneath the metallic shield, and the second feature is arranged over the metallic shield, at least one of the first and second features extends in a radial direction relative to the other of the first and second features to capture the metallic shield with the retention feature; and
wherein a portion of the inner barrel includes an irregularly shaped circumferential edge forming a body, the irregularly shaped circumferential edge has a sheared edge extending interiorly from the circumferential edge, the first feature is provided by the sheared edge extending radially outward relative to the body, the sheared edge is axially blocked by the outer barrel to provide the retention feature.

9. A cable assembly comprising:
coaxially arranged inner and outer barrels, the outer barrel overlaps a portion of the inner barrel, the inner and outer barrels respectively include first and second features that cooperate with one another to form a retention feature;
a cable including at least one wire surrounded by an inner insulator covered in a metallic shield, wherein the metallic shield is arranged in between the inner and outer barrels;
wherein the first feature is arranged beneath the metallic shield, and the second feature is arranged over the metallic shield, at least one of the first and second features extends in a radial direction relative to the other of the first and second features to capture the metallic shield with the retention feature; and
wherein a portion of the inner barrel includes an irregularly shaped circumferential edge forming a body, the irregularly shaped circumferential edge has a circumferentially extending portion providing an edge, the first feature is provided by the edge extending radially outward relative to the body, the edge is axially blocked by the outer barrel to provide the retention feature.

10. A method of assembling a cable comprising the steps of:
a) providing first and second features respectively provided on an inner barrel and an outer barrel, wherein at least one of the first and second features extends in a radial direction relative to the other of the first and second features;
b) inserting the cable into the outer barrel;
c) inserting an end of the inner barrel underneath a metallic shield;
d) aligning the first and second features to provide a retention feature; and
e) capturing the metallic shield between the first and second features of the inner and outer barrels and preventing relative axial movement of the inner and outer barrels relative to one another, wherein the second feature is a window, and the capturing includes crimping the outer barrel adjacent to the window, wherein the first feature is in the window, and the capturing includes plastically deforming a portion of the outer barrel to provide an innermost diameter that is less than an outermost diameter of the first feature.

11. The method of claim 10 , wherein the first feature is provided by a flange at an end of the inner barrel that is flared radially outward.

12. The method of claim 11 , wherein the second feature is a window and the first feature is arranged within the window, the flange is provided about a circumference of the end, the flange is axially aligned with the window.

13. The method of claim 10 , wherein the second feature is a window and the first feature is arranged within the window, the first feature is provided by a protrusion in the inner barrel that is arranged axially inboard of an end, the protrusion is axially and circumferentially aligned with the window.

14. The method of claim 10 , wherein the cable includes at least one wire surrounded by an inner insulator covered in the metallic shield, and step c) includes inserting the end of the inner barrel between the inner insulator and the metallic shield, and wherein step e) includes securing one of the inner and outer barrels to a terminal connector having an outer housing, and wherein the metallic shield is grounded to the outer housing, wherein the cable includes a nonconductive sheathing covering the metallic shield, and the other of the inner and outer barrels are secured over the nonconductive sheathing.

15. The method of claim 10 , wherein step d) includes sliding the outer barrel axially over the inner barrel and the metallic shield.

16. The method of claim 10 , wherein prior to performing step a), comprising a step of a1) forming the first feature by bending a circumferential flange radially outward on a terminal end of an inner barrel blank.

17. The method of claim 10 , wherein prior to performing step a), comprising a step of a1) forming the first feature by deforming a protrusion axially inboard of a terminal end of an inner barrel blank, and wherein step d) includes circumferentially aligning the protrusion with a window providing the second feature.
