Strain Relief Assembly With Shaft Locking for Angled Cable Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strain relief assemblies lack flexibility and versatility in securing cables from multiple orientations, as they are typically fixed and unable to accommodate cables entering from various angles effectively.
Innovation Solution
An adjustable strain relief assembly with a base, an elongate support member, and a rotatable elongate strain relief member featuring a cable receiving part and a securing mechanism, allowing for limited rotation and secure cable attachment from different angles through a ball and socket mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed strain relief assembly is used, then the structure is simple and stable, but it cannot accommodate cables from multiple orientations
Solution Approach 1:
The strain relief member is designed to be rotatable about its longitudinal axis, transforming a static fixed assembly into a dynamic adjustable one. This allows the cable receiving surfaces to be oriented at different angles to accommodate cables from multiple directions while maintaining structural stability through the rotation mechanism
2Ease of operation
If the strain relief member is made rotatable for flexible cable routing, then cable management flexibility is improved, but the device complexity increases
Solution Approach 1:
The securing mechanism is pre-configured with a shaft that can be inserted through the cable to lock the strain relief member in place. This preliminary preparation of the securing mechanism allows for easy operation - users simply insert the shaft through the cable and into the bore to lock the desired position, without requiring complex adjustment procedures
3Stability of the object's composition
If the shaft is designed to prevent rotation when secured, then cable position stability is improved, but it limits adjustability when not secured
Solution Approach 1:
The shaft is designed to transition between two states: when inserted through the cable and into the bore, it prevents rotation and provides stable cable positioning; when removed, the strain relief member becomes freely rotatable, allowing adjustment to accommodate cables from various orientations. This dynamic state change resolves the contradiction between stability and adaptability

AI summary
A strain relief assembly is disclosed comprising a support for mounting on a tray or the like and an elongate support member to which is rotatably mounted a strain relief member. The strain relief member is secured to the support member by a securing mechanism comprising a shaft which travels within a shaft receiving bore between a secured position, wherein a first shaft end of the shaft presses against a free end of the second portion and thereby preventing rotation of the elongate strain relief member and a released position wherein the shaft is positioned away from the free end of the second portion and such that the elongate strain relief member is rotatable.
