RF Connector Inspection Windows for Contact Mounting Checks

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing connectors face challenges in determining the proper mounting of RF and ground contacts within the cover shell, and conducting energization tests due to limited space for probe placement.

Innovation Solution

The connector design includes RF and ground linker members exposed through inspection windows in the insulation part, allowing visual confirmation of mounting and providing space for probe placement during tests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the contact is mounted inside the cover shell, then the mounting is hidden and difficult to determine, but the space for probe arrangement is also reduced

Engineering Contradiction:

Improvemounting status determinationVSAvoidspace for probe arrangement

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The connector is divided into multiple components: the cover shell, the insulation part, and the contact. The insulation part is further segmented to include inspection windows that expose specific portions of the contact. This segmentation allows the contact to be mounted inside the cover shell for reliability while still enabling visual inspection and probe access through the inspection windows.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inspection window acts as an intermediary element between the contact and the external environment. It allows visual confirmation of contact mounting and provides a pathway for probe insertion without requiring the contact to be fully exposed or the cover shell to be opened, thus maintaining both reliability and testability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the contact is fully exposed, then mounting status is easily determined and testing is facilitated, but the connector structure becomes more complex and protection is reduced

Engineering Contradiction:

Improvevisual confirmation and testingVSAvoidconnector structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Instead of fully exposing the contact or maintaining complete coverage, the inspection window provides localized exposure of specific portions of the contact. This local quality approach allows visual confirmation and testing access while maintaining the overall enclosed structure, thus balancing ease of operation with structural simplicity and protection.

Inventive Principle:

Principle #3Local quality
