Noise Current Absorber Holder With Bidirectional Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise current absorbers for electric wires are difficult to detach due to engagement structures that can only be released from a specific direction, making it challenging when the device is positioned deeply within equipment or surrounded by complex structures, and some designs fail to release engagement even when oriented correctly.
Innovation Solution
A holder with through holes allowing insertion from either end, featuring elastically deformable engaging and engaged portions, locking claws, and a bridge mechanism that enables release from either direction, along with a restricting portion to prevent excessive displacement and maintain relative positions for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an engagement structure with a specified release direction is used, then the engagement can be released from the specified direction, but it cannot be released from the opposite direction when the noise current absorber is attached in certain orientations
Solution Approach 1:
The patent applies inversion by creating a through hole that allows the jig to be inserted from either direction (specified or opposite). The engaging portion and engaged portion are designed symmetrically with the through hole penetrating both ends, enabling the release operation to be performed from any orientation, thus resolving the contradiction between ease of operation and adaptability to different orientations.
2Object-affected harmful factors
If the noise current absorber is attached to a position deep inside equipment or surrounded by various structures, then it provides effective noise absorption, but the engagement cannot be released due to limited access for operation
Solution Approach 1:
The through hole design allows the jig to be inserted from either end, providing flexibility in access direction. This enables operators to release the engagement from positions that would otherwise be inaccessible, resolving the contradiction between maintaining effective noise absorption at difficult-to-reach positions and enabling easy detachment.
3Adaptability or versatility
If two pairs of engagement structures are provided, then one may allow release from specified direction while the other from opposite direction, but the noise current absorber still cannot be detached when orientations are mismatched
Solution Approach 1:
The patent merges the functionality of multiple engagement structures into a single through hole design. Instead of having separate engagement structures with different release directions, the through hole integrates both access paths (specified and opposite directions) into one unified structure, allowing both engagement pairs to be released from either direction, thus resolving the orientation mismatch problem.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy detachment of the noise current absorber from electric wires by allowing engagement release from either specified or opposite directions, preventing misalignment and unnecessary twisting, thus facilitating operation and reducing operational difficulty.
Implementation Method 1
When the jig inserted in the through hole is used for applying the external force to the engaging portion or the engaged portion, the engaging portion or the engaged portion is elastically deformed, and thus the engagement is released.
Implementation Method 2
the pair of magnetic bodies in the cylindrical shape surrounds the electric wire from an outer peripheral side. As a result, the pair of magnetic bodies magnetically forms a closed magnetic path and exerts intended noise current absorbing capacity

AI summary
A holder for a noise current absorber in one aspect of the invention comprises a pair of accommodating portions, and one or more pairs of an engaging portion and an engaged portion. The accommodating portion accommodates a magnetic body. The engaging portion and the engaged portion are engaged with each other and maintain a state that a pair of the magnetic bodies exhibits a cylindrical shape or an annular shape. The engaging portion and the engaged portion form a through hole that penetrates in an insertion direction of the engaging portion. When at least one of the engaging portion and the engaged portion is elastically deformed by using a jig inserted in the through hole, engagement between the engaging portion and the engaged portion is released.
