Solution Overview
Problem
Conventional orthogonal electrical connector systems face limitations in data transfer speeds due to prohibitive crosstalk levels, especially in miniaturized and high-speed electronic communications.
Innovation Solution
The development of an orthogonal electrical connector system featuring vertically oriented electrical contacts with shorter distances between mating and mounting ends, which reduces crosstalk and enables higher data transfer rates by using insulative housings and leadframe assemblies with ground plates to shield signal contacts.

If conventional right-angle connectors are used in orthogonal systems, then the connector structure is simple and easy to manufacture, but data transfer speeds are limited due to prohibitive crosstalk levels
Solution Approach 1:
The patent transitions from conventional right-angle connectors to vertical connectors where electrical contacts are oriented perpendicular to the substrate surface. This dimensional change in contact orientation reduces the parallel proximity of adjacent signals, thereby minimizing crosstalk and enabling higher data transfer speeds while maintaining structural simplicity
Solution Approach 2:
The patent modifies key geometric parameters of the connector, specifically the contact orientation angle (from 45 degrees in right-angle connectors to perpendicular/90 degrees in vertical connectors) and contact spacing. These parameter changes reduce electromagnetic interference between adjacent contacts, lowering crosstalk levels and enabling higher speed data transmission
2Volume of moving object
If signal contacts are closely spaced to achieve miniaturization, then device size is reduced, but undesirable interference or cross talk occurs between adjacent signal contacts
Solution Approach 1:
By orienting electrical contacts vertically perpendicular to the substrate rather than at angles, the patent reduces the horizontal projection area of adjacent contacts. This allows closer spacing of contacts in the horizontal plane while maintaining adequate electromagnetic isolation, achieving miniaturization without excessive crosstalk
Solution Approach 2:
The patent introduces ground contacts as intermediary elements positioned between adjacent signal contacts. These ground contacts act as electromagnetic shields that block interference between neighboring signal paths, enabling closer spacing while maintaining signal integrity and reducing crosstalk
