Solution Overview

Problem

Existing connector assemblies occupy a large area on circuit boards due to the parallel orientation of metal shielding cages, limiting the installation of additional electronic components and affecting performance.

Innovation Solution

A connector assembly with a vertically mounted metal shielding cage, where the receiving chamber extends perpendicular to the circuit board, reducing the occupied area and allowing for more components, featuring fastening feet for secure fixation and improved grounding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the metal shielding cage is mounted parallel to the circuit board, then the connector assembly provides adequate shielding, but it occupies a large area on the circuit board

Engineering Contradiction:

Improveelectromagnetic shieldingVSAvoidarea occupied on circuit board

Core Design Contradiction:

Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The metal shielding cage is rotated from a parallel orientation to a vertical orientation perpendicular to the circuit board. This dimensional change allows the receiving chamber to extend in the vertical direction rather than occupying horizontal space, thereby reducing the area occupied on the circuit board while maintaining shielding effectiveness

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the metal shielding cage is oriented vertically, then the area occupied on the circuit board is reduced, but the structural stability may be affected

Engineering Contradiction:

Improvearea occupied on circuit boardVSAvoidstructural stability

Core Design Contradiction:

Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The metal shielding cage is divided into multiple segments: a bottom wall portion, side wall portions, and a top wall portion. This segmentation allows each part to be optimally positioned and secured, with the bottom wall providing stable base attachment to the circuit board and the side walls providing structural support for the vertical orientation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The insulating body is nested within the metal shielding cage, with the electrical connector positioned inside the receiving chamber. This nested arrangement provides mutual support and stabilization, ensuring the vertical structure remains stable while minimizing the area occupied on the circuit board

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A connector assembly includes an electrical connector and a metal shielding cage. The electrical connector includes an insulating body and a number of conductive terminals configured to be mounted to a circuit board. The insulating body includes a mating slot configured to receive a mating connector. The metal shielding cage is shielded on a periphery of the electrical connector. The metal shielding cage includes a receiving chamber in communication with the mating slot. The receiving chamber and the mating slot are configured to receive the mating connector along a first direction. The first direction is perpendicular to the circuit board. The metal shielding cage is provided with at least one fastening foot configured to be fixed to the circuit board.
