Connector Cable Entry Shield and Locking Device Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical cable connectors are susceptible to signal degradation due to electromagnetic interference, which affects the reliable transfer of light signals between fiber ends and conductors.
Innovation Solution
A connector design featuring a cable entry shield made of electro-conductive material that grips around the cable entry, combined with a pivotable locking device and resilient section, provides effective shielding against electromagnetic interference, enhancing signal transfer quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is designed without a cable entry shield, then the device complexity is reduced, but electromagnetic interference affects signal transfer quality
Solution Approach 1:
The cable entry shield is integrated with the locking device base, combining two separate functions (shielding and locking) into a single unified structure. This reduces the overall number of components while maintaining both electromagnetic shielding capability and locking functionality, thus improving signal transfer quality without proportionally increasing device complexity
Solution Approach 2:
The base of the locking device serves dual purposes: it forms part of the electromagnetic shielding structure at the cable entry and simultaneously provides the locking mechanism functionality. This multi-functional design allows the connector to achieve both shielding and locking capabilities through a single structural element
2Reliability
If multiple separate parts are used for the cable entry shield, then the shielding effectiveness is improved, but the ease of manufacture decreases
Solution Approach 1:
The shield is designed as a single integrated part rather than multiple separate components. This unified structure maintains continuous electromagnetic shielding effectiveness while eliminating the need for multiple assembly steps, thereby improving ease of manufacture without compromising shielding performance

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves signal transfer quality by minimizing electromagnetic interference, ensuring accurate alignment and secure connection of fiber ends, thereby maintaining reliable light signal transmission.
Implementation Method 1
The resilient section can for example comprise a U-turn section and an actuation section connecting the U-turn section to the one or more latches for pivoting the latches to the release position against the action of the resilient section

AI summary
A connector including a housing with a cable entry and a contact face presenting one or more conductors for signal transfer to associated conductors of a complementary connector. The connector includes a cable entry shield of an electro-conductive material gripping around the cable at the cable entry. The cable entry shield can for example be formed by a pin holder for holding alignment pins and the base of a locking device, jointly gripping around the cable.
