Wire Routing Connector Layout for Signal Transmission Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connectors with bent and routed wires face issues where power and signal wires can approach each other, leading to degradation of transmission characteristics, especially in limited spaces.
Innovation Solution
The connector design includes a housing with a module accommodation chamber and a routing space where wires are drawn out with bent portions intersecting the insertion direction, ensuring they are spaced apart in the front-rear and lateral directions, and utilizing a resilient member with separate sealing holes to maintain this separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If wires are bent and routed inside a limited space to reduce connector length, then the connector length is reduced, but the transmission characteristics are degraded due to mutual approach of power wire and signal wire
Solution Approach 1:
The patent applies dimensionality change by routing wires in three-dimensional space using bent portions with specific radii. The first wire is bent in a first direction while the second wire is bent in a second direction, utilizing spatial separation in multiple dimensions to maintain transmission characteristics while achieving compact connector length. The bent portions are positioned at different heights and angles, effectively using vertical and lateral dimensions to prevent wire proximity.
Solution Approach 2:
The routing space is segmented into distinct regions for different wires. The first wire and second wire are routed through separate paths defined by their respective bent portions, creating isolated segments that prevent mutual interference. The bent portions act as segmentation elements that divide the routing space into independent wire channels, ensuring that power and signal wires do not approach each other even in a compact connector.
2Volume of moving object
If wires are routed in a compact routing space, then the connector size is reduced, but the interval between wires decreases causing transmission characteristic degradation
Solution Approach 1:
The patent utilizes three-dimensional routing with bent portions that extend in multiple directions and planes. The first bent portion and second bent portion are positioned at different spatial coordinates, using vertical height differences and angular orientations to maintain adequate wire separation. This multi-dimensional approach allows compact routing space volume while preserving transmission characteristics through spatial isolation of wires.
Solution Approach 2:
The bent portions of the wires are designed with specific curvature radii to control the spacing between adjacent wires. By optimizing the bend radius and curvature of the wire paths, the patent ensures that wires maintain sufficient interval even when routed through a compact volume. The curved paths prevent sharp angles that would cause wire crowding, thereby maintaining transmission characteristics within a reduced routing space.

A dielectric 30 to be accommodated into a module accommodation chamber (11,131) includes a first cavity 46 and a second cavity 31 located below the first cavity 46. A first wire (90, 180) drawn out into a routing space (12, 132) from the rear end of the first cavity 46 includes a first bent portion (91, 181), and a second wire (100, 190) drawn out into the routing space (12, 132) from the rear end of the second cavity 31 includes a second bent portion (101, 191) bent in the same direction as the first bent portion (91, 181). The rear end of the first cavity 46 is located behind that of the second cavity 31.
