Solution Overview
Problem
Existing electrical connectors face challenges in achieving high-speed signal transmission and effective shielding, which are not adequately addressed by current technologies.
Innovation Solution
The electrical connector design includes a conductive housing with terminal module installation slots surrounded by walls, featuring surrounding grooves and open slots to house conductive terminals, which are connected to cables, enhancing shielding and reducing signal crosstalk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical connector structures are used, then manufacturing and assembly are simpler, but shielding effect and signal transmission quality are insufficient
Solution Approach 1:
The conductive housing is segmented into multiple portions (first conductive housing portion, second conductive housing portion, third conductive housing portion) that are distributed around the terminal module installation slot. Each portion contributes to the shielding effect, and their combined arrangement creates a comprehensive shielding structure without requiring a fully enclosed complex housing.
Solution Approach 2:
The shielding structure is optimized locally by positioning specific conductive housing portions at strategic locations (first, second, and third positions around the slot) rather than uniformly enclosing the entire connector. This localized approach provides effective shielding where signal transmission occurs while maintaining manufacturing simplicity.
2Speed
If signal transmission speed is increased, then data transmission performance improves, but signal crosstalk and interference increase
Solution Approach 1:
The conductive housing portions act as intermediary shielding elements between adjacent signal terminals and external environments. These intermediary conductive structures redirect electromagnetic interference and prevent direct coupling between signals, enabling high-speed transmission without excessive crosstalk.
Solution Approach 2:
The shielding structure is designed in advance to counteract potential electromagnetic interference before it can affect signal transmission. The conductive housing portions are pre-positioned to block interference paths, allowing high-speed signals to transmit without experiencing crosstalk or external electromagnetic effects.

AI summary
An electrical connector includes a first module. The first module includes a first conductive housing, a first terminal module and a number of first cables. The first conductive housing includes a first base portion and a first protruding portion. The first base portion includes a first terminal module installation slot extending along a first direction and a first mounting groove communicating with the first terminal module installation slot along the first direction. The first terminal module installation slot includes a first surrounding groove close to the first mounting groove and a first open slot away from the first mounting groove. The first surrounding groove is surrounded by wall portions of the first conductive housing along a circumferential direction, and the first open slot communicates with the receiving slot.
