Telescopic Insulating Apparatus for Metallic Busbar Interconnections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating methods for metallic busbars, such as using electric varnish or heat shrink tubes, are costly and inflexible, as they do not allow for easy length adjustments, posing a risk of accidents due to uninsulated interconnection parts.
Innovation Solution
A telescopic insulating apparatus comprising a first and second insulated member with a securing member that slides through slots, allowing adjustable length coverage of the interconnection part, and a blocking structure to secure the member in place, preventing unexpected contraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric varnish is used for insulation, then insulation is achieved, but manufacturing costs increase
Solution Approach 1:
The patent uses a disposable insulating sleeve made of insulating material that covers the interconnection part of metallic strips. This single-use insulating component replaces expensive electric varnish while maintaining insulation effectiveness, thereby reducing manufacturing costs without compromising reliability.
2Reliability
If plastic cover or heat shrink tube is used, then insulation is achieved, but length adjustment is limited
Solution Approach 1:
The patent employs a telescopic structure with sliding members that allow the insulating sleeve to dynamically adjust its length. The sliding mechanism enables the sleeve to extend or contract along the metallic strips, providing continuous length adjustment capability that adapts to different installation requirements, unlike fixed-length plastic covers or heat shrink tubes.
3Adaptability or versatility
If telescopic structure is used for adjustment, then length adaptability is improved, but structural complexity increases
Solution Approach 1:
The insulating sleeve is divided into multiple segments or sections that can slide relative to each other. Each segment is a simple insulating component, and their combination through sliding connections creates the telescopic functionality. This segmentation approach achieves length adjustability while keeping individual components simple and the overall structure manageable.
4Adaptability or versatility
If securing member is made movable for telescopic adjustment, then length adjustment is enabled, but stability against vibration decreases
Solution Approach 1:
The patent introduces a blocking structure as an intermediary element between the sliding securing member and the insulating sleeve. This blocking structure prevents the securing member from sliding back unintentionally due to vibrations or external forces, while still allowing deliberate length adjustment. The blocking structure mediates between the need for movability (adjustment) and stability (vibration resistance).

AI summary
An insulating apparatus for a metallic busbar is disposed on an interconnection part of a first strip and a second strip of the metallic busbar. The insulating apparatus includes a first insulated member, a second insulated member and a securing member. The first insulated member is formed with at least one slot. The second insulated member overlaps the first insulated member. The securing member passes through the second insulated member and the slot of the first insulated member to be slidably disposed in the slot, so that the first insulated member and the second insulated member are movable in a telescopic manner. The first insulated member and the second insulated member can cover the interconnection part of the first and second strips. The insulating problem of the interconnection part of a metallic busbar is solved, shortening the manufacturing period and manufacturing conveniently with lower cost.
