Shield Connector Assembly Detection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shield connectors for automobiles are prone to erroneous assembly due to the terminal holder coming off from the inner housing when the upper and lower shield shells are attached, leading to improper assembly.
Innovation Solution
Incorporating a detection portion on one shell member of the shield shell that overlaps with the terminal holder's surface during insertion, preventing the shell from being attached incorrectly and ensuring proper assembly by regulating its attachment state.

Engineering Contradiction Analysis
1Reliability
If the upper and lower shield shells are attached to the inner housing, then the shield connector provides noise shielding and structural completeness, but the terminal holder may come off from the inner housing causing erroneous assembly
Solution Approach 1:
The detection portion is designed to detect the insertion state of the terminal holder before the shield shell is fully attached to the inner housing. This preliminary detection prevents erroneous assembly by identifying when the terminal holder has come off, allowing the assembly process to be corrected before final attachment, thus ensuring assembly reliability while maintaining ease of operation
Solution Approach 2:
The detection portion provides feedback information about the terminal holder's insertion state during the assembly process. This feedback mechanism allows the assembler to know whether the terminal holder is properly positioned before completing the attachment of the shield shell, preventing erroneous assembly and ensuring reliable connection

AI summary
A shield connector includes plural female terminals 2, a connector housing 3, and a shield shell 8. The connector housing 3 includes a terminal holder 6 that holds the plural female terminals 2 and an inner housing 5 into which the terminal holder 6 is inserted. The shield shell 8 includes an upper shield shell 25 and a lower shield shell that are attached to each other so as to cover the outer periphery of the inner housing 5. The upper shield shell 25 includes an extension wall 30 which detects the state where the terminal holder 6 is being inserted into the inner housing by overlapping with at least a part of a surface 6a of the terminal holder 6 on the rear end side in an insertion direction toward the inner housing 5 in the state where the upper shield shell is attached to the inner housing 5 and by coming into contact with the terminal holder 6 so as to regulate the upper shield shell 25 from being attached to the inner housing 5 in the state where the terminal holder 6 is being inserted into the inner housing 5.
