Angled Push-Pull Connector Assembly for Strain-Stable Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Angled connectors experience mechanical and electrical connection issues due to strain when force is applied to the cable end, leading to potential damage and unreliable connections.
Innovation Solution
The angled connector features a positive-locking arrangement of insulating and housing parts that distribute forces perpendicular to the insertion direction, using anti-rotation elements to secure the insulating body and housing parts together, ensuring stable electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connector uses an angled cable end design, then the connector can be inserted into a complementary connector receptacle in a specific insertion direction, but the angled cable end puts great strain on the mechanical and electrical contact between the connector and the receptacle when force is applied
Solution Approach 1:
The connector is divided into multiple segments: a first connector section that forms an angle with a second connector section, and a positive-locking arrangement that can move between locked and unlocked positions. This segmentation allows the connector to maintain its angled insertion capability while isolating the strain from the electrical contacts through the movable locking mechanism.
Solution Approach 2:
The positive-locking arrangement is designed to be movable between a locked position (where it engages with the receptacle) and an unlocked position (where it disengages). This dynamic design allows the connector to adapt to applied forces by transitioning between states, preventing force transmission to the electrical contacts while maintaining connection stability when locked.
2Reliability
If the connector uses a fixed positive-locking arrangement, then the electrical connection is stable, but the connector cannot be easily assembled and disassembled
Solution Approach 1:
The positive-locking arrangement is designed as a movable component that can transition between locked and unlocked positions. When locked, it provides stable electrical connection; when unlocked, it allows easy assembly and disassembly. This dynamic design resolves the contradiction by providing both stability during operation and ease of handling during maintenance.
Solution Approach 2:
The connector incorporates a self-locking mechanism that automatically engages when the connector is inserted into the receptacle, providing stable electrical connection without requiring additional fastening steps. Conversely, applying force in a specific direction automatically unlocks the mechanism, enabling easy disassembly without tools or complex procedures.
3Ease of operation
If the connector allows force application to the cable end, then the connector is easy to operate, but the mechanical and electrical connection becomes unreliable due to strain
Solution Approach 1:
The positive-locking arrangement is designed to move in response to forces applied to the cable end. When force is applied during operation, the locking mechanism can transition from locked to unlocked state, preventing force transmission to the electrical contacts. This dynamic response maintains connection reliability while preserving ease of operation.
Solution Approach 2:
The positive-locking arrangement acts as an intermediary between the cable end and the electrical contacts. It absorbs and isolates forces applied to the cable end, preventing them from reaching the mechanical and electrical connection points. This intermediary function allows easy operation at the cable end while protecting the connection reliability.
