Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed differential connectors experience uneven stress and high plugging resistance when applied to vibration environments or offset plugging positions due to single-sided contact structures, affecting transmission performance.
Innovation Solution
The design of a female and male connector with an elastic clamping structure, where female signal and ground contacts form a plugging space with the male connector, allowing interaction forces on both sides and compensating for vibration or offset through elastic deformation, enhancing contact reliability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-sided contact structure is adopted, then connector integration is improved, but transmission performance deteriorates due to uneven stress in vibration environments
Solution Approach 1:
The patent transitions from single-sided contact to asymmetric dual-sided contact structure, where contact pieces are arranged on both sides of the insulation body. This asymmetric arrangement allows the connector to handle forces from multiple directions, resolving the contradiction between integration and reliability in vibration environments.
Solution Approach 2:
The patent adds a new dimension to the contact structure by arranging contact pieces not only in the plugging direction but also in lateral directions. This multi-dimensional contact arrangement enables the connector to withstand forces from various directions, improving reliability without sacrificing integration.
2Device complexity
If single-sided elastic attachment is used, then connector structure is simplified, but plugging resistance increases due to lateral force from same direction
Solution Approach 1:
The patent employs asymmetric dual-sided elastic attachment where contact pieces on opposite sides provide counteracting elastic forces. This asymmetric arrangement distributes plugging forces more evenly, reducing overall plugging resistance while maintaining structural simplicity.
Solution Approach 2:
The patent applies the counterweight principle by positioning contact pieces on both sides of the insulation body. During plugging, the contact pieces on opposite sides exert counteracting elastic forces that balance each other, reducing the net lateral force and plugging resistance.

AI summary
A contact module, a female connector and a male connector, wherein the female contact unit of the female connector includes signal contacts arranged in pairs and ground contacts corresponding to the signal contacts, a side surface of each signal contact facing the corresponding ground contact includes a signal contact portion in conductive contact with the signal contact portion of an adapter connector, a side surface of each ground contact facing the corresponding signal contact includes a shielding contact portion in electrical contact with the ground contact of the adapter connector, and a plugging space for plugging the contact module of the adapter connector is between the signal contacts and the ground contacts. The female connector enables the adapted contact unit to be clamped between the corresponding signal contact and the corresponding ground contact to realize corresponding conduction.
