Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector assemblies have complex configurations, making them inconvenient to assemble.
Innovation Solution
A cable connector assembly featuring a connector with a contact module, a mounting ring with external screw threads, and a shielding shell with internal screw threads, allowing for easy assembly by screwing the shielding shell onto the mounting ring and attaching a front shell to the shielding shell in a front-to-back direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connector assembly uses multiple separate components (upper inner shell half, lower inner shell half, upper outer shell half, lower outer shell half, mounting portion with slot), then the structural integrity and shielding effectiveness are improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines multiple separate shell components into a single integrated connector housing. The upper and lower inner shell halves are merged into one piece, and the upper and lower outer shell halves are merged into another single piece. This integration maintains the protective and shielding functions while eliminating the complexity of assembling multiple separate components.
Solution Approach 2:
The connector housing is designed to perform multiple functions simultaneously: it provides structural protection for the contact module, electromagnetic shielding, and cable securing all in one component. The mounting ring integrated into the housing also serves dual purposes as both a structural element and a cable fixation mechanism.
2Reliability
If a cable connector assembly uses multiple separate components with interlocking mechanisms, then the connection reliability is improved, but the ease of operation and assembly convenience deteriorate
Solution Approach 1:
The patent integrates the cable securing function directly into the connector housing through an integrated mounting ring, eliminating the need for separate cable glands or clamps. This single-piece design maintains secure cable attachment while allowing straightforward assembly by simply inserting the cable into the ring.
Solution Approach 2:
The mounting ring with its opening designed to fit around the cable allows the cable to be self-secured during assembly. The elastic element within the mounting ring automatically engages with the cable, providing self-service cable fixation without requiring additional fastening operations or complex adjustment steps.
3Object-affected harmful factors
If a cable connector assembly uses traditional multi-component design, then the electromagnetic shielding effectiveness is improved, but the manufacturing complexity and assembly time increase
Solution Approach 1:
The patent integrates the shielding function directly into the connector housing structure itself, rather than using separate shielding components. The housing material and structure are designed to provide electromagnetic shielding, eliminating the need for additional shielding layers or components and thereby simplifying manufacturing while maintaining EMI protection.
Solution Approach 2:
The connector housing appears to utilize composite construction or material properties that provide both structural integrity and electromagnetic shielding characteristics in a single component, reducing the need for multiple specialized components while maintaining shielding effectiveness.
