Stab-Type Connector With Nested Load And Locking Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector systems for fluid conduits in oil and gas extraction systems face challenges in providing a durable, low-profile, sealed connection that can withstand axial loads and has limited space constraints, while ensuring reliable fluid flow and easy installation.
Innovation Solution
A novel stab-type connector system featuring a collar with a load ring and locking ring configuration that securely couples tubular members in an end-to-end arrangement, utilizing threaded connections and set screws for alignment and locking, allowing for axial load resistance and easy assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional connector system is used to couple fluid conduits, then the connection can provide structural strength, but the profile height increases and space constraints are not accommodated
Solution Approach 1:
The connector employs nested rings (load ring, locking ring, seal ring) positioned within the collar structure, where each ring is contained within the collar's internal space. This nesting arrangement provides multiple functional elements (load bearing, locking, sealing) without increasing the overall profile height of the connector assembly.
2Force
If a connector with load ring and locking ring configuration is used, then axial load resistance is improved, but device complexity increases
Solution Approach 1:
The connector is divided into distinct functional segments: collar (receives tubular members), load ring (bears axial loads), locking ring (secures components), and seal ring (provides sealing). Each ring is independently positioned and functions separately, allowing the complex load-bearing and locking functions to be achieved through simple, modular components rather than a single complex structure.
3Reliability
If a sealed connection is implemented to ensure reliable fluid flow, then fluid sealing is improved, but manufacturing complexity increases
Solution Approach 1:
The seal ring is positioned within the collar to engage with the tubular members and create a sealed connection. The sealing function is achieved through the inherent geometry and elastic properties of the seal ring, which self-adjusts to accommodate manufacturing tolerances and provides reliable sealing without requiring additional sealing mechanisms or complex assembly procedures.

AI summary
A connector is provided, in one embodiment, the connector includes a collar (16) configured to receive first and second components (12,14). In this embodiment, the connector may also include a load ring (50) configured to be received in a groove (46) of the second component (12) and to move into and out of engagement with the collar (16) when the second component (12) is received by the collar (16). The connector of this illustrative embodiment may also include a locking ring (62) configured to inhibit disengagement of the load ring (50) from the collar (16). In some embodiments, engagement of the load ring (50) and the collar (16) effects securing of the first and second components (12, 14) to one another.
