Abstract

A component assembly comprises a first housing and a second housing jointed by a coupling assembly. The coupling assembly comprises a coupling body and a floating torque ring axially slidably interfaced to the coupling body. The coupling body comprises a first threaded portion engaged with a first threaded coupling section of the first housing, and a second threaded portion engaged with a second threaded coupling section of the second housing. The floating torque ring is radially fixed to the coupling body, and is axially movable relative to the coupling body. Rotation of the floating torque ring causes relative rotation of the coupling body, thereby threadably joining the first housing and the second housing about the coupling body independent of axial positions of the housings due to the axially movable floating torque ring. A method of joining the housings is provided.

First claim

What is claimed is:

1. A component assembly, comprising:
a first housing comprising a first raised portion that extends inward toward a center of the first housing, the first raised portion comprising a threaded coupling section and an inner mating section;
a second housing comprising a second raised portion that extends inward toward a center of the second housing, the second raised portion comprising a threaded coupling section and an inner mating section; and
a coupling assembly joining the first housing to the second housing, the coupling assembly comprising:
a coupling body comprising a first threaded portion engaged with the threaded coupling section of the first housing, and a second threaded portion engaged with the threaded coupling section of the second housing; and
a floating torque ring axially slidable relative to and engageable with the coupling body,

wherein rotation of the floating torque ring causes rotation of the coupling body, and drawing of the first and second housings together to press against the floating torque ring, thereby joining the first housing and the second housing about the coupling body independent of an axial position of the first housing relative to an axial position of the second housing.

2. The component assembly of claim 1 , wherein the coupling body comprises a plurality of perimeter protrusions, and wherein the floating torque ring comprises a plurality of inner recesses operable to interface with and engage the plurality of perimeter protrusions, respectively, such that the floating torque ring is radially fixed to the coupling body.

3. The component assembly of claim 2 , wherein the plurality of perimeter protrusions are formed radially around an outer perimeter portion of the coupling body, and wherein the plurality of inner recesses are formed radially around an inner portion of the floating torque ring at corresponding positions relative to respective perimeter protrusions.

4. The component assembly of claim 1 , further comprising an electromagnetic seal formed by the joining of the first and second housings, the electromagnetic seal configured to protect at least one electronics assembly supported within the component assembly.

5. The component assembly of claim 1 , further comprising at least first and second elastomeric seals, each situated between the coupling body and respective first and second housings.

6. The component assembly of claim 1 , wherein an outer circumferential surface area defined along the first and second housings and the floating torque ring is generally curvilinear.

7. The component assembly of claim 1 , wherein the first threaded coupling section is threaded in an opposite direction relative to the threads of the second threaded coupling section.

8. The component assembly of claim 1 , wherein the first threaded coupling section comprises threads formed about an inner area of the first housing, and the second threaded coupling section comprises threads formed about an inner area of the second housing, and wherein the first and second threaded portions of the coupling body each comprise threads formed about an outer area of the coupling body.

9. The component assembly of claim 1 , wherein the floating torque ring is situated axially between the first and second threaded portions of the coupling body, and is situated axially between respective ends of the first and second housings.

10. The component assembly of claim 1 , wherein the coupling body comprises an inner cylindrically-shaped surface having a generally curvilinear surface along an entire surface area of the inner cylindrically-shaped surface.

11. The component assembly of claim 1 , wherein the component assembly is devoid of fasteners protruding inwardly into an inner chamber area defined by the coupling body.

12. A missile comprising at one component assembly of claim 1 , wherein the first housing comprises a generally cylindrically-shaped missile housing section, and the second housing comprises a generally cylindrically-shaped missile housing section.

13. The missile of claim 12 , wherein an inner surface area proximate the at least one component assembly is generally continuous along the at least one component assembly.

14. The missile of claim 12 , wherein an outer surface area proximate the at least one component assembly is generally continuous along the at least one component assembly.

15. A method of coupling housings with a coupling assembly, comprising:
obtaining a first housing comprising a first raised portion that extends inward toward a center of the first housing, the first raised portion having a first threaded coupling section and an inner mating section, and a second housing comprising a second raised portion that extends inward toward a center of the second housing, the second raised portion having a second threaded coupling section and an inner mating section;
engaging the first threaded coupling section to a first threaded portion of a coupling body, and engaging the second threaded coupling section to a second threaded portion of the coupling body;
securing a floating torque ring to the coupling body, situated between the first and second housings; and
rotating the floating torque ring to rotate the coupling body, thereby causing the first housing and the second housing to be drawn together about the coupling body independent of an axial position of the first housing relative to an axial position of the second housing.

16. The method of claim 15 , further comprising rotating the floating torque ring a sufficient degree so as to cause the first and second housings to press against the floating torque ring.

17. The method of claim 15 , wherein rotating the floating torque ring facilitates axial movement of the floating torque ring relative to the coupling body upon one of the first or second housings engaging the floating torque ring.

18. The method of claim 15 , further comprising sealing at least one electronic component, supported within an inner chamber area defined by the first and second housings, from electromagnetic interference upon joining the first and second housings.

19. The method of claim 15 , wherein rotating the floating torque ring comprises rotating a tool engaged to a perimeter portion of the floating torque ring.

20. The method of claim 15 , wherein the floating torque ring is axially movable relative to the coupling body upon one of the first or second housings engaging the floating torque ring.
