Abstract

A rotary crimping tool assembly includes a tool housing defining a crimping chamber, and one or more crimp wheels within the crimping chamber. The crimping chamber is configured to receive the portion of the structure in proximity to the crimp wheel(s). The crimp wheel(s) are configured to be pressed into and rotated relative to the portion of the structure to form one or more crimps in the portion of the structure.

First claim

What is claimed is:

1. A rotary crimping tool assembly configured to crimp a portion of a structure, the rotary crimping tool assembly comprising:
a tool housing defining a crimping chamber; and
one or more crimp wheels within the crimping chamber, wherein the crimping chamber is configured to receive the portion of the structure in proximity to the one or more crimp wheels, and wherein the one or more crimp wheels are configured to be pressed into and rotated relative to the portion of the structure to form one or more crimps in the portion of the structure;
wherein each of the one or more crimp wheels comprises a conductor crimp member and a sealing crimp member, wherein the conductor crimp member has a different shape than the sealing crimp member, wherein the conductor crimp member includes a smooth, arcuate outer surface having a central equator from which lateral portions recede, wherein the sealing crimp member has a plurality of seal-indenting features, wherein the conductor crimp member has a first height and the sealing crimp member has a second height, wherein the first height exceeds the second height, the conductor crimp member is configured to form a first crimp at a first depth into the portion of structure, and the sealing crimp member is configured to form a second crimp at a second depth into the portion of structure, and wherein the first depth is deeper than the second depth.

2. The rotary crimping tool assembly of claim 1 , wherein the tool housing comprises a first frame secured to a second frame.

3. The rotary crimping tool assembly of claim 2 , further comprising:
an adjustable mount adjustably secured to one or both of the first and second frames; and
one or more rollers rotatably secured to the adjustable mount, wherein the one or more rollers comprise a smooth cylindrical body,
wherein the one or more crimp wheels are secured to one of the first and second frames, wherein the crimping chamber is configured to receive the portion of the structure between the one or more crimp wheels and the one or more rollers, wherein the adjustable mount is configured to be adjusted to compress the portion of the structure between the one or more crimp wheels and the one or more rollers, and wherein the one or more crimp wheels and the one or more rollers are configured to be rotated about the portion of the structure to form the one or more crimps.

4. The rotary crimping tool assembly of claim 3 , wherein the one or more rollers comprises first and second rollers rotatably secured to first and second roller axles that are secured to the adjustable mount, wherein the one or more crimp wheels are rotatably secured to a crimp axle that is rotatably secured to one of the first and second frames, wherein the crimp axle resides within a central plane, and wherein the first and second roller axles reside within first and second roller planes, respectively, that are parallel with and offset from the central plane.

5. The rotary crimping tool assembly of claim 3 , further comprising an adjustment member operatively connected to the adjustable mount, wherein the adjustment member is configured to adjust the adjustable mount in relation to the crimping chamber.

6. The rotary crimping tool assembly of claim 5 , wherein the adjustment member comprises a threaded shaft connected to a handle, wherein the threaded shaft is threadably secured within a portion of one of the first or second frames.

7. The rotary crimping tool assembly of claim 6 , wherein the adjustment member further comprises a retaining structure extending from a distal end of the threaded shaft, wherein the retaining structure is secured within a recessed area of the adjustable mount.

8. A method of crimping a structure, the method comprising:
positioning a portion of the structure to be crimped into a crimping chamber of a rotary crimping tool assembly;
pressing one or more crimp wheels into the portion of the structure to be crimped, wherein the pressing comprises forming one or more initial crimps into the portion of the structure; and
rotating the one or more crimp wheels relative to the portion of the structure to form one or more full crimps in the portion of the structure, wherein the one or more crimps are configured to secure the first portion of the structure to a second portion of the structure;
wherein each of the one or more crimp wheels comprises a conductor crimp member and a sealing crimp member, wherein the conductor crimp member has a different shape than the sealing crimp member, wherein the conductor crimp member includes a smooth, arcuate outer surface having a central equator from which lateral portions recede, wherein the sealing crimp member has a plurality of seal-indenting features, wherein the conductor crimp member has a first height and the sealing crimp member has a second height, wherein the first height exceeds the second height, the conductor crimp member is configured to form a first crimp at a first depth into the portion of structure, and the sealing crimp member is configured to form a second crimp at a second depth into the portion of structure, and wherein the first depth is deeper than the second depth.

9. The method of claim 8 , wherein the positioning comprises positioning the portion of the structure between the one or more crimp wheels and one or more rollers, and wherein the compressing comprises pressing the portion of the structure between the one or more crimp wheels and the one or more rollers, and wherein the rotating comprises rotating the one or more crimp wheels and the one or more rollers about the portion of the structure to form the one or more full crimps.

10. The method of claim 8 , wherein the pressing comprises engaging an adjustment member to compress the one or more crimp wheels into the portion of the structure to be crimped.

11. The method of claim 8 , further comprising temporarily restraining the portion of the structure from movement.

12. The method of claim 8 , wherein the forming of the one or more initial crimps comprises forming multiple initial crimps into the portion of the structure with a single crimp wheel, and wherein the rotating comprises forming multiple full crimps in the portion of the structure with the single crimp wheel.

13. The method of claim 8 , wherein the forming of the one or more initial crimps comprises forming initial first and second crimps at first and second depth, respectively, into the portion of structure, wherein the first depth is deeper than the second depth.

14. A rotary crimping tool assembly configured to crimp a terminal housing of a contact terminal into an insulated wire, wherein a conductive portion of the insulated wire is within the terminal housing, the rotary crimping tool assembly comprising:
a tool housing defining a crimping chamber;
an adjustable mount configured to be moved within the crimping chamber; and
one or more crimp wheels within the crimping chamber, wherein the crimping chamber is configured to receive the terminal housing in proximity to the one or more crimp wheels, and wherein the adjustable mount is configured to urge the contact terminal into the one or more crimp wheels, and wherein the tool housing is configured relative to the terminal housing to form one or more crimps in the terminal housing;
wherein each of the one or more crimp wheels comprises a conductor crimp member and a sealing crimp member, wherein the conductor crimp member has a different shape than the sealing crimp member, wherein the conductor crimp member includes a smooth, arcuate outer surface having a central equator from which lateral portions recede, wherein the sealing
