Removable Load Bar Modular Plug for Reliable Field Crimping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Improper termination of network connectors in the field leads to poor connectivity and device failure due to inconsistent wire lengths, resulting in incomplete engagement with the crimping portion of the plug.
Innovation Solution
A modular plug system with a load bar featuring extensions that engage openings in the plug housing, ensuring proper alignment and crimping of wires, and a cap unit made of flame-resistant material to prevent sparks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wires are hand cut to a length that will allow the wires to engage with the crimping portion of the plug, then the connector can be terminated outside a closed environment, but the wires are cut inconsistent lengths resulting in poor connectivity and device failure
Solution Approach 1:
The load bar is pre-configured with positioning features that guide wires into the correct position before crimping. The extensions on the load bar engage with openings in the plug housing to establish proper wire alignment and length engagement prior to the crimping operation, eliminating the need for precise hand-cutting in the field.
Solution Approach 2:
The load bar acts as an intermediary component between the wires and the plug housing. It provides a standardized interface that ensures consistent wire engagement through its extensions that mate with openings in the housing, thereby maintaining manufacturing precision during field termination operations.
2Ease of operation
If a traditional modular plug is used for field termination, then the connector can be installed outside a closed environment, but improper terminations lead to degraded device performance or device failure
Solution Approach 1:
The load bar with extensions engages automatically with the openings in the plug housing to self-align and self-position the wires during insertion. This self-service mechanism ensures proper termination without requiring skilled manual intervention, thereby maintaining high connection reliability during field installation.
Solution Approach 2:
The engagement between the extensions on the load bar and the openings in the plug housing provides mechanical feedback that confirms proper positioning and alignment. This feedback mechanism ensures that wires are correctly engaged before crimping, preventing improper terminations and enhancing connection reliability.
