Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors face challenges in quickly and reliably connecting ground terminals to the cable's ground shielding layer due to the risk of short circuits when ground wires come into contact with signal wires, complicating the assembly process and reducing yield rates.
Innovation Solution
A cable connector design featuring a housing with a terminal module that includes conductive terminals with a connecting portion linking first and second ground terminals, where the connecting portion is partially wrapped and fixed on the ground shielding layer around the signal wires, eliminating the need for separate ground wires and thus preventing short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If two ground wires are used to improve shielding effect, then shielding effectiveness is improved, but assembly complexity increases and yield rate decreases due to short circuit risks
Solution Approach 1:
The patent extracts the ground wire function from the cable and integrates it into the connector housing through a metal shield structure. The metal shield is pre-integrated into the housing, eliminating the need for separate ground wires that need to be assembled, thus reducing assembly complexity while maintaining shielding effectiveness.
Solution Approach 2:
The patent merges the ground shielding function with the connector housing by integrating the metal shield directly into the housing structure. This combination eliminates the need for separate ground wire components and their associated assembly processes, reducing both assembly complexity and short circuit risks while preserving electromagnetic shielding.
2Object-affected harmful factors
If two ground wires are used to improve shielding effect, then shielding effectiveness is improved, but manufacturing yield decreases due to short circuit risks during assembly
Solution Approach 1:
The patent removes the ground wire assembly step from the manufacturing process by pre-integrating the metal shield into the housing. This eliminates the risk of short circuits during ground wire connection, improving manufacturing yield while maintaining shielding effectiveness.
Solution Approach 2:
The metal shield is pre-integrated into the housing during connector manufacturing, before the final assembly with the cable. This preliminary integration ensures proper grounding connections are already in place, eliminating the risk of short circuits during final assembly and improving overall manufacturing yield.
3Object-affected harmful factors
If ground wires are used for grounding, then shielding effect is improved, but assembly time increases due to complex connection processes
Solution Approach 1:
The patent extracts the ground wire connection process from the assembly sequence by pre-integrating the metal shield into the housing. This eliminates the time-consuming steps of ground wire routing, connection, and insulation, significantly reducing assembly time while maintaining shielding effectiveness.
Solution Approach 2:
By merging the ground shielding function into the housing structure, the patent eliminates the need for separate ground wire assembly steps. The metal shield is already positioned and connected during housing manufacturing, reducing assembly time to minimal steps while preserving electromagnetic shielding performance.

AI summary
A cable connector includes a housing, a terminal module and a cable connected to the terminal module. The terminal module includes multiple groups of conductive terminals. At least one group of conductive terminals include two signal terminals, a first ground terminal and a second ground terminal. The at least one group of conductive terminals include a connecting portion connecting the first ground terminal and the second ground terminal. The cable includes signal wires electrically connected to the signal terminals and a ground shielding layer wrapped around a periphery of the signal wires. The connecting portion is at least partially wrapped and fixed on the ground shielding layer. With this arrangement, it is easy to connect the ground terminals and the cable ground shielding layer in order to achieve a better shielding effect.
