Connector With Solid Buckle and Double-Layer Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire-side and board-side connectors suffer from structural weaknesses, including fragile buckle pieces, unstable core wire geometry, limited diameter compatibility, and inadequate electromagnetic shielding, leading to poor signal transmission stability and flexibility.
Innovation Solution
The wire-side connector features a solid buckle structure with multiple clamp slots and internal mold compounds to stabilize core wire geometry and position, while the board-side connector employs double-layer electric shielding and varied welding feet for enhanced stability and compatibility, along with a flexible external mold compound to accommodate different wire diameters and absorb external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a buckle piece with a single supporting point is used in the wire-side connector, then the plugging operation is simplified, but the mechanical strength of the buckle piece becomes fragile and the bonding strength with the board-side connector is weak
Solution Approach 1:
The buckle piece is divided into multiple supporting points (first supporting point and second supporting point) instead of a single supporting point. This segmentation distributes the mechanical load across multiple locations, enhancing the overall strength and durability of the buckle piece while maintaining the plugging operation functionality.
2Device complexity
If no object is configured to carry and fix discrete core wires, then the device structure is simplified, but the geometry, relative distance, position and dimension of each discrete core wire become unstable
Solution Approach 1:
A wire carrying component is introduced as an intermediary element to hold and position the discrete core wires. This component acts as a mediator that maintains the geometry, relative distances, and positions of the core wires without significantly complicating the overall device structure, thus resolving the instability issue.
3Manufacturing precision
If the plastic case has a fixed accommodating space, then the manufacturing precision is improved, but the adaptability to cable wires with different wire diameters is limited
Solution Approach 1:
The accommodating space of the plastic case is designed with dynamic adjustability, allowing it to adapt to different wire diameters. This may involve movable walls, adjustable clamps, or elastic components that can accommodate varying cable sizes while maintaining precise positioning and manufacturing tolerances.
4Reliability
If the plastic case is made as a rigid plastic case for convenience of plugging, then the plugging stability is improved, but the winding curvature of the cable wire is limited and space is increased
Solution Approach 1:
The plastic case is designed with differentiated local properties: rigid sections in areas requiring structural stability and plugging reliability, and flexible or compliant sections in areas where cable bending and winding are needed. This local quality variation allows the case to maintain plugging stability while accommodating cable wire curvature and reducing overall space requirements.

AI summary
A connecting structure comprises a board-side connector and a wire-side connector. The board-side connector comprises a frame pedestal surrounding an accommodating chamber; a metal outer shell covering the exterior of the frame pedestal; a metal inner shell mounted to a mounting hole at a rear end of the accommodating chamber; and a transmission main body mounted to an interior of the metal inner shell. The wire-side connector comprises a transmission main body having multiple terminals having multiple first ends soldered to discrete core wires of a wire cable and multiple second ends configured to contact terminals of the board-side connector; a clamp cage at a rear side of the transmission main body; and a plastic case surrounding an accommodating chamber, wherein the accommodating chamber receives second ends of the terminals.
