Movable Reed Base Connection with Thinned Positioning Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting structure between the movable contact part and the base in magnetic latching relays suffers from inconsistent assembly tightness due to metal part thickness variations, leading to unreliable positioning accuracy.
Innovation Solution
A thinned structure is introduced at the movable contact lead-out piece, fitted with a positioning rib and boss in the base slot, enhancing clamping reliability and reducing material thickness variation, while maintaining current flow through the connection position between the movable contact piece and lead-out piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the movable contact lead-out piece uses standard metal part thickness, then the structure is simple and easy to manufacture, but the assembly may be too loose or too tight due to thickness variation, resulting in poor positioning accuracy
Solution Approach 1:
The movable contact lead-out piece features a thinned structure only at the position requiring positioning (where it fits into the base slot), while other areas maintain standard thickness. This localized modification reduces material thickness variation at the critical positioning area, improving clamping reliability and positioning accuracy without unnecessarily complicating the entire structure.
2Reliability
If the movable contact lead-out piece is thinned at the positioning location, then the material thickness variation is reduced and clamping reliability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
Instead of thinning the entire movable contact lead-out piece, only the specific region that requires precise positioning and clamping is thinned. This localized approach reduces material thickness variation where it matters most, improving clamping reliability and assembly consistency while minimizing the impact on manufacturing complexity.
3Stability of the object's composition
If the movable contact lead-out piece has uniform thickness, then the manufacturing process is simple, but the assembly tightness is inconsistent in practical use
Solution Approach 1:
The movable contact lead-out piece transitions from uniform thickness to a non-uniform thickness distribution, with a thinned region at the positioning location. This localized thickness variation ensures consistent assembly tightness by reducing material variation at the critical interface with the base slot, while the rest of the structure maintains sufficient thickness for structural integrity.

AI summary
A connecting structure for connecting a movable reed and a base. The movable reed comprises a movable reed piece and a movable reed outlet unit; a first end part of the movable reed piece is connected to a movable contact, and a second end part is fixedly connected to a first end part of the movable reed outlet unit; the movable reed piece and the movable reed outlet unit form a V shape; a second end part of the movable reed outlet unit is configured as an outlet connecting part; the base is provided with a slot; a thinned structure extends outwards from the first end part of the movable reed outlet unit; the thinned structure is fitted in the slot of the base; positioning ribs are arranged in the slot of the base, and the positioning ribs abut against a side surface of the thinned structure. By utilizing the thinned structure, the material thickness variation of the movable reed outlet unit can be reduced, and the clamping reliability is improved.
