Movable Connector Elastic Pins Misalignment Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors that absorb misalignment, such as those with flexible pieces or ring-shaped spring members, often result in increased size and manufacturing costs due to the need for complex shapes and additional structural support.
Innovation Solution
A movable connector design featuring a housing with elastic mounting pins arranged in a circular ring on one or two outer peripheral sides, which are inserted into corresponding recesses, allowing for relative movement and simplifying the shape and manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible pieces are provided on all outer peripheral sides of the housing, then misalignment absorption is improved, but the connector size increases
Solution Approach 1:
The mounting pin is segmented into multiple elastic pieces (first elastic piece, second elastic piece, third elastic piece) arranged in a circular ring. This segmentation allows each piece to independently deform and absorb misalignment while maintaining a compact overall structure, resolving the contradiction between misalignment absorption capability and connector size.
2Reliability
If ring-shaped spring members are used, then misalignment absorption is improved, but the manufacturing cost increases due to complex shaping
Solution Approach 1:
Instead of using a single ring-shaped spring member that requires complex shaping, the invention segments the spring into multiple simpler elastic pieces arranged in a circular ring. Each elastic piece has a simpler geometry that is easier to manufacture, reducing overall manufacturing cost while maintaining the misalignment absorption function through collective deformation of all pieces.
3Force
If spiral spring members are used to reduce resilient force, then the spring force is optimized, but additional bearing structures are required increasing complexity
Solution Approach 1:
The invention applies local quality by providing clearance between the elastic pieces and the inner wall of the mounting recess. This clearance allows the elastic pieces to deform freely within a specific range, optimizing the spring force characteristics without requiring additional bearing structures. Each elastic piece deforms locally within its own clearance space, eliminating the need for complex external bearing mechanisms.
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
This design enables a downsized connector with reduced manufacturing costs while maintaining the ability to absorb misalignment, as the elastic pins can move within the recesses without the need for extensive structural support.
Implementation Method 1
the mounting pin is capable of relative movement inside the mounting recess in directions that intersect a direction in which the mounting pin is inserted into the mounting recess

AI summary
A movable connector disclosed in the present description includes: a connector having a housing; and a connector mounting part to which the housing is movably mounted. The housing is provided with at least one mounting pin constituted by a plurality of elastic pieces arranged in a circular ring, and the connector mounting part is provided with mounting recesses (mounting tubular portions) that hold the mounting pin in a state in which it is inserted into the corresponding mounting recess. The mounting pin is capable of relative movement inside the mounting recess in directions that intersect a direction in which the mounting pin is mounted into the mounting recess, and the mounting pin is provided on one or two of the outer peripheral sides of the housing.
