Electrical Connector Ground Member Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with ground members face issues of poor contact due to inadequate retention, leading to displacement and manufacturing/installation errors, making it difficult to confirm reliable electrical conduction between the ground member and terminal.
Innovation Solution
The electrical connector design includes a ground member retained on the inward side of a retaining body, with a detecting part exposed to facilitate easy confirmation of electrical conduction by performing a continuity test, and multiple ground members are used to enhance retention and contact reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ground member is retained on the inward side of the retaining body, then the reliability of contact between ground member and ground terminal is improved, but the ease of detecting electrical conduction condition deteriorates
Solution Approach 1:
The detecting part is extracted from the ground member and exposed to the outside through the retaining body. This allows the ground member to be retained on the inward side for reliable contact while the detecting part extends outward for easy electrical conduction detection, resolving the contradiction between contact reliability and detection ease.
2Device complexity
If the ground member is retained only by retaining protruding parts, then the device complexity is reduced, but the stability of ground member position deteriorates
Solution Approach 1:
The retaining body is segmented into multiple retaining protruding parts that are distributed across the base material. These multiple retention points work together to securely hold the ground member in position, providing stability while maintaining a relatively simple overall structure.
3Ease of manufacture
If the ground plate is retained by retaining protruding parts on the plate surface, then the ease of manufacture is improved, but the reliability of ground function deteriorates due to displacement risk
Solution Approach 1:
The retaining protruding parts are integrated directly into the base material structure, merging the retention function with the base material. This combination provides secure retention of the ground member while maintaining ease of manufacture, as the retaining features are formed as part of the base material rather than separate components.

AI summary
Example implementations involve an electrical connector and a test method of the electrical connector, wherein the electrical conduction condition between a ground member and a ground terminal can be easily confirmed while reliably contacting the ground member and ground terminal. Electrical connector involves a plurality of terminals including two types of terminals, namely, signal terminals and ground terminals; a retaining body, made of an insulating material, that arranges and retains the plurality of terminals in a condition where the signal terminals and ground terminals are intermingled; and a ground member retained by the retaining body on the inward side of the retaining body, in a condition contacting at least two ground terminals; wherein the ground member has a detecting part exposed from the retaining body in order to detect an electrical conduction condition between the ground terminals and the ground member.
