High-Speed Connector Rigid Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connector alignment methods for high-speed signal transmission suffer from stress-induced pin damage and misalignment, leading to unreliable signal transmission due to forced coupling and increased frequency of fastening, which can result in loose connections or broken fastening parts.
Innovation Solution
A connector design featuring a pin array assembly with a base mold and a top mold, where the top mold moves relative to the base mold based on the degree of engagement between pins, allowing for rigid alignment through a fastening mechanism with rigid fastening parts and insertion parts, minimizing physical stress on pins and enabling precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional forced coupling alignment method is used, then alignment speed is improved, but pin damage and connection reliability deteriorate
Solution Approach 1:
The connector employs a dynamic alignment mechanism where the housing can move relative to the circuit board along the insertion direction. This dynamic adjustment allows the connector to automatically compensate for alignment errors during the coupling process, transforming the static forced coupling into a dynamic self-aligning system that reduces pin stress while maintaining connection reliability
Solution Approach 2:
The alignment groove and alignment protrusion structure performs preliminary alignment action before the main coupling occurs. The alignment protrusion on the housing fits into the alignment groove on the circuit board, establishing correct positional relationship in advance, which prevents forced coupling and pin damage during the subsequent coupling process
2Manufacturing precision
If forced coupling is applied to achieve alignment, then alignment is achieved, but stress on pins increases leading to damage
Solution Approach 1:
The invention introduces a housing as an intermediary component between the circuit board and the connector pins. The housing carries the alignment protrusion that interfaces with the alignment groove on the circuit board, mediating the alignment process and protecting the pins from direct stress during coupling. The housing absorbs and distributes the coupling forces, preventing concentrated stress on the pins
3Stability of the object's composition
If frequent fastening operations are performed, then connection stability is improved, but fastening parts become loose or broken
Solution Approach 1:
The connector employs a self-aligning mechanism through the alignment groove and protrusion that automatically compensates for positional deviations during each coupling operation. This self-service alignment function eliminates the need for precise manual alignment and reduces stress on fastening parts, allowing frequent coupling operations without degradation of connection stability or fastening part durability

AI summary
Proposed is a connector for high-speed signal transmission with a rigid alignment function. The connector allows rigid alignment between pin arrays as a part of the connector moves slightly in the left-right or front-rear direction depending on the degree of engagement between corresponding pins when coupled to a counterpart connector.
