Connector Terminal Inclination Angles Signal Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors suffer from signal degradation due to mismatched inclination angles of terminal middle portions, leading to increased noise and signal loss in differential signal transmission.
Innovation Solution
The design includes a configuration where the middle portions of terminals are inclined at specific angles relative to each other, with ground or low-speed signal terminals positioned between differential signal terminals to maintain parallelism and reduce inclination angles, thereby minimizing signal degradation and impedance mismatch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all middle portions are arranged in parallel at regular intervals with the same width, then manufacturing precision is improved, but signal degradation increases due to large inclination angles on the opposite side
Solution Approach 1:
The patent applies local quality by differentiating the inclination angles of middle portions based on their position. Middle portions on the signal terminal side have a first inclination angle, while middle portions on the opposite side have a second inclination angle that is smaller than the first. This local differentiation reduces signal degradation while maintaining arrangement regularity.
Solution Approach 2:
The patent introduces asymmetry by making the inclination angles of middle portions asymmetric with respect to the terminal arrangement. Instead of uniform inclination angles, the middle portions have different inclination angles depending on their position relative to the signal terminals, which optimizes signal transmission while maintaining manufacturing precision.
2Device complexity
If middle portions are inclined at larger angles to accommodate terminal spacing, then device complexity is reduced, but signal degradation increases
Solution Approach 1:
The patent applies local quality by differentiating the inclination angles of middle portions based on their position. Middle portions on the signal terminal side have a first inclination angle, while middle portions on the opposite side have a second inclination angle that is smaller than the first. This local differentiation reduces signal degradation while maintaining arrangement regularity.
3Manufacturing precision
If all terminals have the same inclination angle, then manufacturing precision is improved, but impedance mismatch increases causing signal degradation
Solution Approach 1:
The patent applies local quality by differentiating the inclination angles of middle portions based on their position. Middle portions on the signal terminal side have a first inclination angle, while middle portions on the opposite side have a second inclination angle that is smaller than the first. This local differentiation reduces signal degradation while maintaining arrangement regularity.
Solution Approach 2:
The patent applies parameter changes by varying the inclination angle parameter of middle portions based on position. The inclination angle is changed from a uniform value to position-dependent values, where middle portions on the opposite side have smaller inclination angles than those on the signal terminal side, optimizing both impedance matching and signal transmission.

AI summary
A connector including one and the other first terminals, a second terminal, and a third terminal that are partially held in a body and spaced from each other along a first direction. The middle portion of each first terminal extends obliquely and has parallel edges. The second middle portion of the second terminal extends obliquely and has parallel edges being non-parallel to the edges of the first middle portions. The third terminal extends between the one first terminal and the second terminal and includes a third middle portion extending obliquely. Of the non-parallel edges of the third middle portion, one edge next to the second middle portion is substantially parallel to the edges of the second middle portion, and the other edge next to the first middle portion of the one first terminal is substantially parallel to the edges of the first middle portion of the one first terminal.
