Hinged Electrical Connector Backshell Adapter for Cable Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angled cable sheath terminating backshell adapters often obstruct further cable insertion due to the cable end contacting the adapter's interior wall, requiring difficult manipulation to reach the termination port, and lack efficient closure mechanisms for the cable sheath.
Innovation Solution
A hingedly interconnected backshell adapter with a seam dividing it into sections, where the cable sheath clamps function as both adapter closing and clamping means, featuring a radially extending ridge and annular clamping mechanisms like spiral springs or 'C' clips to securely retain the cable sheath, while being made of radiopaque materials to resist electromagnetic flux.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional angled backshell adapter is used, then the adapter provides cable termination functionality, but the cable end contacts the interior wall blocking further insertion
Solution Approach 1:
The adapter housing is divided into two separable halves that can be opened to form a V-shape, allowing the cable to be inserted without contacting blocking interior walls. The segments can be positioned to guide the cable smoothly into the termination port.
Solution Approach 2:
The adapter transitions from a static closed structure to a dynamic open structure during cable installation. The housing halves can be pivoted or separated to create an open V-shape configuration, then closed after cable insertion to secure the cable in place.
2Reliability
If the adapter uses separate closing and clamping mechanisms, then the cable sheath is securely retained, but the device complexity increases
Solution Approach 1:
The cable sheath clamp is designed to perform dual functions: it acts as both the closing element that secures the housing halves together and the clamping element that retains the cable sheath. This multi-functional design eliminates the need for separate closing and clamping mechanisms.
Solution Approach 2:
The closing and clamping functions are merged into a single integrated cable sheath clamp component. This clamp simultaneously performs the mechanical closure of the adapter housing and the securing of the cable sheath, reducing part count and simplifying the overall structure.
