Triangular Cable Clamp for Simultaneous High-Voltage Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable clamps require significant assembly space and effort, as cables need to be separated and tensioned individually, making them inefficient for installation in confined spaces and increasing the workload.
Innovation Solution
A compact, space-saving clamp design with a triangular cross-sectional clamping body and pairs of clamping jaws that allow for simultaneous strain relief of three power cables without tension, featuring adjustable fastening means and rubber inserts for secure cable fixation, enabling easier assembly and installation in tight spaces.

Engineering Contradiction Analysis
1Reliability
If individual clamps are used for each cable, then each cable can be secured separately, but the cables have to be moved apart during assembly requiring larger assembly space and additional work
Solution Approach 1:
The patent combines multiple cable clamping functions into a single integrated clamp body with multiple clamping jaws that can simultaneously secure multiple cables. The clamp body includes several clamping jaws arranged to accommodate multiple cables side by side, eliminating the need for separate clamps for each cable and reducing the assembly space required.
Solution Approach 2:
The clamp body is segmented into multiple clamping jaws, each capable of independently clamping a cable. This segmentation allows each cable to be secured separately while maintaining a compact overall structure that doesn't require large assembly space.

If a compact clamp design is used to reduce assembly space, then space requirements are reduced, but cable fixation security may be compromised
Solution Approach 1:
The clamp body is segmented into multiple clamping jaws, each capable of independently clamping a cable. This segmentation allows each cable to be secured separately while maintaining a compact overall structure that doesn't require large assembly space.
Solution Approach 2:
Each clamping jaw is designed with specific local features optimized for cable clamping, including clamping surfaces with appropriate friction characteristics and geometric shapes that match cable profiles. This ensures reliable cable fixation in each local clamping zone while maintaining overall compactness.

AI summary
A cable clamp (10) for holding cables, preferably high-voltage cables, comprises an elongated clamping body (12) for receiving the cables. The elongated clamping body (12), which is provided with three cable entry channels (13a, 13b, 13c), has a lower part (13) and an upper part (14) that form paired clamping jaws (15, 16) for fixing the cables (13a, 13b, 13c) in the cable entry channels (13a, 13b, 14a) of the clamping body. This results in a compact, space-saving design for the cable clamp (12), which simultaneously ensures a completely tensile-resistant fixation of the power cables.
