Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connection devices face misalignment issues between the plate conductive member and the opening, leading to unstable connections, especially when high precision is required or significant misalignment occurs.
Innovation Solution
The electrical connection device features a contact piece with an arm and leg portion that can float on the wiring board, allowing for leverage to enhance contact force and accommodate misalignment, with a resin cover for protection and a metal support member for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plate conductive member is inserted through a fixed opening in the conventional electrical connection device, then the connection structure is simple, but misalignment occurs between the plate conductive member and the opening leading to unstable connections
Solution Approach 1:
The contact piece is designed with a fulcrum mechanism that allows it to rotate dynamically around the base portion. When the plate conductive member is inserted, the contact piece pivots to accommodate misalignment, transforming from a static fixed-structure to a dynamic adaptive-structure that maintains stable electrical connection despite positioning variations
Solution Approach 2:
The contact piece changes its angular parameter (rotation angle) around the fulcrum to adapt to misalignment. By allowing the contact angle to vary dynamically, the system accommodates different insertion positions and directions while maintaining reliable electrical contact between the plate conductive member and the wiring board
2Adaptability or versatility
If resilient contact bands or clamping bodies are used to accommodate misalignment, then some misalignment is tolerated, but high contact precision and significant misalignment cannot be simultaneously achieved
Solution Approach 1:
The contact piece rotates dynamically around the fulcrum to precisely position the contact point on the plate conductive member. This rotational degree of freedom allows the system to adapt to significant misalignment while maintaining high contact precision through controlled pivoting motion, overcoming the limitations of fixed resilient bands or clamping bodies
Solution Approach 2:
The invention merges the fulcrum mechanism with the contact piece to create a unified pivoting assembly. This combination integrates the adaptive misalignment accommodation function directly into the contact structure, eliminating the need for separate resilient bands or clamping bodies and achieving both adaptability and precision simultaneously
3Stability of the object's composition
If the electrical connection device is completely fixed on the back plate with fixing screws, then the device is stable, but it cannot accommodate misalignment of the plate conductive member
Solution Approach 1:
The device is segmented into a fixed base portion (attached to back plate with screws) and a movable contact piece portion (rotating around fulcrum). This segmentation allows the base to remain stable and fixed while the contact piece adapts dynamically to misalignment, achieving both device stability and misalignment tolerance simultaneously

Implementation Method 1
the arm portion of the contact piece contacts with one planar surface of the plate conductive member, the arm portion is urged toward a side of the planar surface of the wiring board through the contact, and in response to this, the leg portion is urged to the side of the wiring board having the base portion as a fulcrum

AI summary
An electrical connection device is to be attached to a wiring board for holding a plate conductive member so that the wiring board is electrically connected to the plate conductive member. The electrical connection device includes a contact piece including an arm portion, a leg portion, and a base portion disposed between the arm portion and the leg portion; and a base member to be attached to the wiring board for supporting the contact piece at the base portion thereof. The base member is to be attached to the wiring board so that the base member is movable in parallel to the wiring board. The contact piece is arranged so that the plate conductive member pushes the arm portion to urge the leg portion against the wiring board with the base portion as a pivot when the plate conductive member contacts with the arm portion.
