Electrical Connector Movable Bushing Smooth Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for end-to-end connections of electrical conductors face challenges in secure and easy mounting, particularly due to the need for a smooth outer surface to facilitate the assembly of elastic sleeves, which is disrupted by screw heads and openings, and they struggle with accommodating varying conductor diameters and positional inaccuracies.
Innovation Solution
An electrical connector design featuring a movable conductive bushing within a separate cover member, allowing for tilting and rotational adjustments to center the cable, with a smooth outer surface and bearing pins for secure alignment, and a roughened inner surface for enhanced contact and lubricant retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and openings are used to connect the sleeve to the sleeve cover, then mechanical and electrical connection is achieved, but the outer surface becomes non-smooth which disrupts the grease film and complicates elastic sleeve assembly
Solution Approach 1:
The invention extracts the harmful elements (screw heads and openings) from the outer surface by providing a smooth outer surface that contacts the elastic sleeve, while maintaining the necessary mechanical connection functions through alternative means that do not disrupt the surface smoothness
Solution Approach 2:
The connector is divided into functional zones: the outer surface is segmented to be smooth for elastic sleeve contact, while internal structures handle the mechanical connection functions, separating the surface requirement from the connection requirement
2Ease of manufacture
If a fixed connector design is used, then manufacturing is simplified, but it cannot accommodate varying conductor diameters and positional inaccuracies
Solution Approach 1:
The connector incorporates movable elements that allow adjustment and adaptation to different conductor diameters and positional variations, transforming a static fixed design into a dynamic adaptable structure while maintaining manufacturing simplicity
Solution Approach 2:
The connector design allows for parameter variations (such as movable positions, adjustable clearances) to accommodate different conductor sizes and alignment tolerances, enabling a single design to handle multiple specifications
3Ease of operation
If a smooth outer surface is provided for elastic sleeve assembly, then sleeve mounting is facilitated, but mechanical connection features like screw heads cannot be present
Solution Approach 1:
The harmful surface features (screw heads, openings) are extracted from the outer surface that contacts the elastic sleeve, removing the conflict between smooth surface requirement and mechanical connection features
Solution Approach 2:
The mechanical connection features are relocated to internal dimensions or different spatial locations where they do not interfere with the outer surface smoothness, allowing both smooth outer surface and strong mechanical connection to coexist
