Connector Housing Shielding Sheet Automatic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional manufacturing process of connector housing shielding sheets is inefficient due to lack of operation space for automatic assembly, leading to low production efficiency and deformation of thin elastic sheets during manual assembly.
Innovation Solution
A connector housing design featuring a shielding sheet with a first and second elastic sheet, a first bent portion, and lap portions that are slidably engaged with a mounting passageway, allowing for automatic assembly and improved assembly accuracy by providing sufficient operation space and preventing displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual assembly is used to assemble the two layer elastic sheet on the connector housing body, then the shielding sheet can be assembled, but the production efficiency is very low and the thin elastic sheets are easily deformed
Solution Approach 1:
The shielding sheet is designed with self-service assembly features where the inner and outer elastic sheets automatically position and secure themselves through the U-shaped bent structures that engage with corresponding features on the connector housing body, eliminating the need for manual manipulation and reducing deformation risk
Solution Approach 2:
The shielding sheet is segmented into distinct functional zones: the inner elastic sheet, outer elastic sheet, and U-shaped bent structures, allowing each segment to perform its specific function independently during automated assembly while maintaining overall structural integrity
2Reliability
If the front end and rear end of the shielding sheet are both designed as U-shaped bent structures for connection, then the shielding sheet is securely fixed on the connector housing body, but there is not enough operation space for automatic assembly
Solution Approach 1:
The U-shaped bent structures are designed to engage with the connector housing body in a dimensional sequence during automated assembly, allowing the shielding sheet to be positioned and secured without requiring excessive lateral operation space, as the bending action occurs in a controlled sequential manner
3Adaptability or versatility
If the inner and outer layer elastic sheets are made thin, then the shielding sheet has good flexibility and fit, but the sheets are easily deformed during manual assembly process
Solution Approach 1:
The design incorporates predetermined reinforcement features and support structures that are built into the shielding sheet assembly process before final installation, providing protective support during the vulnerable assembly phase to prevent deformation of the thin elastic sheets while maintaining their flexibility for proper fitting

AI summary
A connector housing includes a housing body having a socket adapted to receive an external electronic module inserted in an insertion direction and a shielding sheet having a first elastic sheet disposed on an inner side of the housing body, a second elastic sheet disposed on an outer side of the housing body, and a first bent portion connected between the first elastic sheet and the second elastic sheet and adapted to be clamped on an edge of the socket. The housing body has an outer wall with a mounting passageway. A free end of the first elastic sheet and/or the second elastic sheet has a pair of lap portions on a pair of sides parallel to the insertion direction. The free end of the first elastic sheet and/or the second elastic sheet is slidably engaged with the mounting passageway in the insertion direction.
