Contact Carrier Spatial Arrangement for Signal Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical plug connectors face challenges in minimizing interference between data and energy transmission channels, with current designs often lacking optimal distribution and separation of contact pairs, which can lead to signal disturbances and reduced transmission efficiency.
Innovation Solution
The contact carrier design features imaginary distance lines between contact pairs that are free of overlaps, with specific arrangements ensuring that second distance lines intersect at a right angle and have greater distances between related pairs, achieving a characteristic impedance greater than 50Ω, and configuring contacts for low voltage data transmission and high voltage energy transmission to minimize mutual interference.

1Productivity
If contacts are arranged in a distributed plane perpendicular to the longitudinal axis, then the plug connector can transmit multiple data and energy channels, but interference between data and energy transmission channels occurs
Solution Approach 1:
The contact carrier is divided into separate functional zones: a first contact region for energy transmission contacts and a second contact region for data transmission contacts. This spatial segmentation physically separates the two types of contacts, reducing electromagnetic interference between energy and data channels while maintaining the ability to transmit multiple channels simultaneously.
Solution Approach 2:
The patent transitions from a two-dimensional planar arrangement of contacts to a three-dimensional distributed arrangement along the longitudinal axis. Contacts are positioned at different axial positions rather than all lying in a single plane, creating additional spatial separation between energy and data contacts to minimize interference.
2Volume of moving object
If data and energy contacts are arranged close together to reduce device size, then the plug connector becomes more compact, but signal disturbances increase
Solution Approach 1:
The contact carrier is segmented into distinct first and second contact regions that are spatially separated along the longitudinal axis. Energy contacts are positioned in the first region while data contacts are positioned in the second region, creating physical distance between them. This segmentation reduces electromagnetic coupling and signal disturbances while maintaining a compact overall device volume.
Solution Approach 2:
The contact carrier structure itself acts as an intermediary element that provides both mechanical support and electromagnetic isolation. The carrier's geometry and material properties mediate the interaction between energy and data contacts, reducing interference while enabling close integration.
3Ease of manufacture
If contacts are distributed without specific geometric constraints, then manufacturing is simpler, but interference between related and unrelated contact pairs cannot be minimized
Solution Approach 1:
The patent applies different spatial arrangement rules to different contact pairs based on their functional relationships. Related contact pairs (energy or data) are arranged with specific geometric constraints to minimize mutual interference, while unrelated pairs are positioned to optimize overall signal quality. This local optimization of contact geometry maintains manufacturing simplicity while reducing interference.
Solution Approach 2:
The patent optimizes specific geometric parameters of the contact arrangement, including the angles and positions of contact pairs relative to the longitudinal axis. By carefully controlling these parameters, the design minimizes electromagnetic interference between contact pairs while maintaining a manufacturable structure with straightforward contact carrier geometry.

AI summary
An electrical plug connector having a housing and a contact carrier held inside the housing. It comprises an electrically insulating base part and at least one pair of first electrical contacts for transmitting energy and multiple pairs of second electrical contacts for transmitting data. The contacts are held in the base part and arranged so as to be distributed in a plane extending essentially perpendicular relative to the longitudinal axis of the contact elements and the contact carrier. First distance lines between the contacts of the pairs of first contacts are free of overlaps with second distance lines between the contacts of the pairs of second contacts.
