Cable Connector Assembly Conductive Shell Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector assemblies face difficulties in assembling the cover and base together due to the complexity of the conductive shell design, making it challenging to combine them effectively.
Innovation Solution
The cable connector assembly features a conductive housing with a metal shell that includes a frame portion and an extension portion with position holes, allowing for easy alignment and locking of the cover and base using bolts through first and second position holes, simplifying the assembly process.

Engineering Contradiction Analysis
1Reliability
If a conductive shell with complex structure (including lateral walls, rear wall, and spring member) is used to enclose the connector, then the shielding and structural integrity are improved, but the assembly difficulty between cover and base increases significantly
Solution Approach 1:
The conductive shell is segmented into a frame portion and an extension portion, with the extension portion further divided into multiple extension arms. This segmentation allows each part to be independently positioned and assembled, reducing the overall assembly difficulty while maintaining the shielding effectiveness of the complete shell structure.
Solution Approach 2:
Position holes are pre-formed in both the conductive shell and the housing before final assembly. This preliminary action eliminates the need for complex alignment operations during assembly, as the bolts can be directly inserted through the pre-aligned position holes, significantly simplifying the assembly process while maintaining structural integrity.
2Reliability
If traditional conductive shell designs are used, then shielding is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
Position holes are pre-formed in both the conductive shell and the housing before final assembly. This preliminary action eliminates the need for complex alignment operations during assembly, significantly improving assembly efficiency while maintaining the shielding effectiveness of the complete shell structure.
Solution Approach 2:
The extension portion of the conductive shell serves multiple functions: it provides electromagnetic shielding, acts as a structural support element, and incorporates position holes that facilitate assembly. This multi-functionality reduces the need for separate components, thereby improving assembly efficiency without compromising shielding effectiveness.

AI summary
A cable connector assembly includes a conductive housing, a pair of PCBs, two cables and a metal shell assembled to the housing. The housing defines a receiving cavity. The PCBs are received in the receiving cavity at different levels. The two cables are located at a rear wall of the housing and electrically connect to the PCBs. The metal shell is assembled to the housing and includes a frame portion, and an extension portion extending forwardly from an upper wall of the frame portion. The frame portion encloses a rear portion of the housing and the extension portion has a pair of first position holes. The housing has a pair of second position holes are aligned with first position holes respectively. Two bolts penetrate through the first position holes and are locked in the second position holes respectively.
