Lever-Locked Cable Closure Ring for Low-Force Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking rings for cable closures in the telecommunications industry require high forces for closure and sealing, making it difficult for installers to close the ring without assistance, leading to increased installation time and the need for skilled operators.
Innovation Solution
A locking ring design featuring two ring sections with locking structures and a lever having a locking rib that engages and disengages from the locking structures, allowing the lever to move from a closed to an open position without tools, facilitating easier assembly and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional locking rings are used for cable closures, then sealing and closure are achieved, but high forces are required making it difficult for installers to close the ring without assistance
Solution Approach 1:
The locking ring is divided into two separable ring sections that can be independently positioned and secured. This segmentation allows the ring to be opened and closed more easily by installers, reducing the force required compared to a traditional single-piece locking ring.
Solution Approach 2:
The locking mechanism incorporates a movable lever with locking ribs that can transition between engaged and disengaged states. This dynamic element allows the ring to be easily opened and closed by simply moving the lever, significantly reducing the force needed for operation while maintaining secure closure when locked.
2Reliability
If traditional locking rings require high forces for closure, then sealing is achieved, but installation time increases and skilled operators are needed
Solution Approach 1:
By dividing the locking ring into two sections with intermediate locking structures, the mechanism achieves reliable sealing through the engagement of multiple locking points while allowing easier manual operation. This eliminates the need for skilled operators and reduces installation time.
Solution Approach 2:
The movable lever with locking ribs provides a simple dynamic mechanism that enables any installer to easily open and close the ring by leveraging mechanical advantage. This maintains sealing reliability through positive locking while dramatically improving installation speed and eliminating the need for specialized training.
3Ease of operation
If a locking mechanism with multiple components is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The locking rib and lever are combined as an integrated unit, and the two ring sections are designed to interlock with complementary locking structures. This merging of components simplifies the overall assembly while maintaining ease of operation through the lever mechanism.
Solution Approach 2:
The locking rib on the lever serves multiple functions: it engages with the locking structure on the ring sections to secure them together, and its movement provides the mechanical advantage needed for easy operation. This multi-functionality reduces the need for separate components, simplifying the overall device while improving ease of assembly.

AI summary
A locking ring for assembly onto a cable closure includes a locking ring includes at least two ring sections, with each ring section having at least one locking structure; and a lever that couples with the at least two ring sections. The lever includes at least one locking rib disposed therein, and the at least one locking rib is configured to engage and disengage from the at least one locking structure such that the lever moves from a closed position in which proximal ends of each ring section are substantially adjacent to an open position in which proximal ends of each ring section are separate.
