Solution Overview

Problem

Existing electrical connectors with SAS transmission interfaces face issues with accurate horizontal positioning during docking, leading to potential damage to the insulating body due to lack of horizontal guidance, which reduces the service life and signal transmission quality.

Innovation Solution

The electrical connector incorporates a shielding body with convex portions that guide the docking connector and prevent scratches on the insulating body, ensuring accurate alignment and enhancing electromagnetic shielding during high-frequency signal transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a guiding body is added to provide horizontal positioning guidance, then positioning accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the shielding body and guiding body into a single integrated component. The shielding body includes guiding surfaces that provide horizontal positioning guidance, eliminating the need for a separate guiding body. This merging approach improves positioning accuracy while avoiding additional complexity from separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shielding body serves multiple functions: it provides electromagnetic shielding for high-frequency signals and simultaneously acts as a guiding body with guiding surfaces for horizontal positioning. This multi-functionality resolves the contradiction by integrating positioning guidance into an existing component rather than adding a separate element.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If the shielding body is made larger to improve shielding effect, then electromagnetic interference resistance is improved, but device complexity and assembly difficulty increase

Engineering Contradiction:
Improveelectromagnetic interference resistanceVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shielding body and guiding body are merged into one component, so the shielding structure itself provides guiding functionality. This eliminates the need for additional guiding components while maintaining effective shielding coverage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shielding body is designed to perform both shielding and guiding functions. The guiding surfaces are formed on the shielding body, allowing it to provide electromagnetic shielding while simultaneously guiding the plug connector during docking.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If separate guiding body and shielding body are used, then positioning and shielding functions are optimized, but assembly complexity and manufacturing cost increase

Engineering Contradiction:
Improvepositioning accuracyVSAvoidease of manufacture
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent integrates the guiding body and shielding body into a single molded component. The shielding body includes guiding surfaces formed as integral parts of its structure, eliminating the need for separate manufacturing and assembly of guiding and shielding components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single shielding body component performs both shielding and guiding functions, simplifying manufacturing by requiring only one molding process and one assembly step rather than separate production and assembly of multiple components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electrical connector includes an insulating body, plural conductive terminals, and a shielding body. The insulating body includes a top board, a bottom board, and two side boards that form a docking chamber. The top board has a first surface, the bottom board has a second surface facing to the first surface, and plural terminal grooves are formed on the first surface and the second surface. Each of the conductive terminals has a contacting portion and a tail portion connected to the contacting portion. The contacting portion is located in a corresponding one of the terminal grooves, and the tail portion is extended to outside of the insulating body. The shielding body has two side walls opposite to each other and is fixed to an opening of the docking chamber in which two convex portions are respectively located on inner surfaces of the side walls.
