Solution Overview

Problem

Existing connectors face difficulty in assembling a shield plate between dielectrics due to challenges in gripping and positioning during assembly.

Innovation Solution

A connector design featuring an outer conductor, dielectrics, inner conductors, a shield member, and locking portions that allow for easy assembly by locking the shield member to the dielectric, preventing misalignment and separation during assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the shield plate is inserted into the gap between dielectrics after assembly, then the shielding function is achieved, but the assembly difficulty increases due to difficulty in gripping the shield plate

Engineering Contradiction:

Improveshielding functionVSAvoidassembly ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The shield member is divided into a shield plate and a shield holder. The shield holder is integrated with the dielectric, while the shield plate is a separate component that can be easily gripped and positioned. This segmentation allows the shield plate to be handled independently during assembly, solving the gripping difficulty while maintaining the shielding function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shield holder acts as an intermediary between the dielectric and the shield plate. It provides a stable mounting structure that facilitates the assembly process by offering grip points and positioning features, making it easier to install the shield plate in the gap between dielectrics.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the shield plate is assembled into the gap between dielectrics, then the shielding is achieved, but the positioning precision deteriorates due to misalignment risk

Engineering Contradiction:

Improveshielding functionVSAvoidpositioning precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The shield holder is pre-integrated with the dielectric during dielectric assembly, establishing precise positioning features before the shield plate is installed. This preliminary action ensures that when the shield plate is subsequently assembled, it aligns correctly with the gap between dielectrics, maintaining high positioning precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention replaces the direct mechanical insertion of the shield plate into the gap with a system where the shield plate is mounted on the shield holder, which is already integrated with the dielectric. This substitution eliminates the need for precise manual positioning during shield plate assembly, as the integrated structure provides inherent alignment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
