Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with tolerance modules face challenges in maintaining stable signal transmission due to displacement errors, particularly in high-density differential connectors, where axial and perpendicular displacements can exceed 1.0mm and 0.6mm respectively, affecting performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tolerance module is added to reduce displacement errors, then connector reliability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the tolerance module directly into the plug structure, merging the tolerance compensation function with the existing plug components. The second housing is integrated into the third housing, and the second contact members are incorporated within the plug assembly, eliminating the need for a separate tolerance module that would require additional assembly steps.
Solution Approach 2:
The plug structure is designed to serve multiple functions: it provides electrical connection through contact members, mechanical support through housings, and tolerance compensation through the movable second housing. This multi-functionality reduces the need for additional specialized components, thereby reducing overall device complexity while maintaining reliability.
2Adaptability or versatility
If floating contact members are used to enable displacement, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs elastic supporting members that change their mechanical parameters ( stiffness, support force) based on displacement magnitude. The elastic pieces are designed with specific material properties and geometric parameters that allow them to provide appropriate support force within the displacement range of 0.05mm to 1.0mm, accommodating variations without requiring extreme manufacturing precision.
Solution Approach 2:
The second contact members are designed to be movable within the second housing, transitioning from a fixed to a dynamic configuration. This dynamic design allows the contact members to automatically adjust their positions in response to displacement errors, improving adaptability while reducing the stringency of manufacturing precision requirements through self-adjustment.
3Productivity
If the connector length is reduced to less than 110mm, then productivity is improved, but stability worsens
Solution Approach 1:
The patent compensates for the reduced axial length by utilizing the radial dimension more effectively. The elastic supporting members are arranged radially around the contact members, providing distributed support that enhances stability despite the shorter overall connector length. This dimensional redistribution maintains structural integrity while enabling compact design for improved productivity.
Solution Approach 2:
The elastic supporting members act as intermediary elements between the housings and contact members, providing cushioning and stability. These intermediaries absorb mechanical stresses and maintain positional stability even in the compact connector design, preventing direct transmission of instability that would otherwise occur in shorter connectors.

Implementation Method 1
elastic supporting members are arranged between the supporting seat and the third housing, and the supporting seat is elastically supported on the stopping boss of the second contact members by means of the elastic supporting members

AI summary
The present invention relates to a connector with a tolerance module. The connector with a tolerance module comprises a socket and a plug adapted to the socket, wherein the socket comprises a first housing, the plug comprises a tolerance module and a third housing, the tolerance module comprises a second housing, the second housing is internally provided with second contact members, the second housing is movably arranged on the third housing in a direction perpendicular to the axial direction of the connector, and the second contact members are floatingly assembled in the second housing to enable displacement in the direction perpendicular to the axial direction of the connector. By adopting the solution above, the second housing is movably arranged on the third housing in the direction perpendicular to the axial direction of the connector, and the second housing only generates translational motion without displacement when the connector is inserted; the tolerance of the plug and the socket is realized by the floating assembly of the second contact members in the second housing, thus improving the discrepancy in the degree of displacement of different second contact members and being beneficial to improving the transmission performance of the connector.
