Floating Connector Plug Structure for Stable High-Speed Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size and weight of circuit board assemblies in electronic devices, coupled with higher signal transmission rates, result in connectors experiencing larger torsional and lateral forces, leading to significant partial mating distances and difficulties in enhancing signal transmission rates.
Innovation Solution
A connector design featuring a floating connector plug with elastic members and stoppers, along with guide assemblies, allows for precise alignment and reduced demating values, enabling efficient signal transmission by allowing the plug to float in multiple planes and directions, and utilizing guide pins and sleeves for coarse positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the quantity of electronic components and integration level are increased to achieve higher signal transmission rates, then the signal transmission rate is improved, but the size and weight of the circuit board assembly increase, causing larger torsional and lateral forces on connectors that lead to larger partial mating distances
Solution Approach 1:
The connector plug is designed to float dynamically within the insertion cavity rather than being rigidly fixed. The first elastic member provides dynamic support that allows the connector plug to adjust its position in response to external forces, maintaining stable electrical connection despite torsional and lateral forces caused by increased circuit board assembly size and weight.
Solution Approach 2:
The first elastic member acts as an intermediary between the fixed housing and the connector plug. It transmits and buffers the forces from the circuit board assembly to the connector plug, reducing the impact of torsional and lateral forces on the mating connection while still providing adequate support for high-speed signal transmission.
2Reliability
If the connector plug is rigidly fixed to reduce partial mating distance, then connection stability is improved, but the connector cannot adapt to misalignment and the signal transmission rate cannot be increased
Solution Approach 1:
The connector plug transitions from a rigid fixed state to a controlled floating state. The first elastic member provides dynamic support that allows the connector plug to adapt to misalignment while maintaining stable connection, enabling both connection reliability and high-speed signal transmission.
Solution Approach 2:
The elastic properties of the first elastic member are carefully selected to provide the right balance between support and flexibility. By changing the stiffness parameter of the elastic member, the system achieves optimal performance for both connection stability and signal transmission rate.
3Adaptability or versatility
If the connector plug is allowed to float freely to improve alignment, then adaptability to misalignment is improved, but connection stability deteriorates due to larger partial mating distances
Solution Approach 1:
The connector plug achieves controlled floating rather than free floating. The first elastic member provides dynamic support that allows the connector plug to adapt to misalignment while maintaining stable connection, enabling both connection reliability and high-speed signal transmission.
Solution Approach 2:
The first elastic member automatically adjusts the connector plug position in response to alignment variations. The elastic force self-regulates to maintain optimal connection while allowing necessary movement for alignment adaptability.
