Insulated Power Cable Connection Tip with Transverse Conductive Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection end pieces for insulated electrical power cables with rigid conductive cores face mechanical stress issues when connected to electrical equipment terminals, leading to potential damage and suboptimal electrical performance.
Innovation Solution
A connection end piece design featuring a conductive contact member formed from a thin metal sheet, shaped to include two series of conductive teeth extending transversely, which are radially active and supported by a clamping member, ensuring secure mechanical and electrical connection without interfering with the cable's insulating sheath, and a fusible screw for secure clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid conductive core is used in the power cable, then electrical connection is ensured, but mechanical stresses are generated at the terminals of electrical equipment
Solution Approach 1:
The connection end piece is divided into two distinct parts: a rigid connection terminal for electrical connection and a flexible connection cable for mechanical flexibility. This segmentation allows the rigid core to maintain electrical connection while the flexible cable absorbs mechanical stresses, resolving the contradiction between electrical reliability and mechanical stress resistance.
2Reliability
If conductive teeth are arranged longitudinally in the axial direction, then electrical contact is established, but manufacturing complexity increases
Solution Approach 1:
The conductive teeth are reoriented from a longitudinal arrangement (axial direction) to a transverse arrangement (radial direction). This dimensional change simplifies manufacturing by allowing the teeth to be formed more easily on the connection terminal while still establishing effective electrical contact with the conductive core, reducing manufacturing complexity without compromising electrical contact reliability.

AI summary
The tip has a rigid conducting core and a connection terminal that is arranged to receive an end of an isolated electric power cable according to an axial direction of insertion. An isolated electric connecting cable comprises a flexible conducting core, where the connecting cable is mechanically subjugated and is electrically connected to the connection terminal. A set of series of conducting teeth (58) extend transversely to the axial direction of insertion, and a set of active parts (59) of the series of conducting teeth extends radially along a clamping mechanism. An independent claim is also included for a method for assembly of a connection tip.
