Triangular Cable Clamp with Paired Jaws for High-Voltage Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable clamps require significant assembly space and effort, particularly when dealing with high-voltage cables, as they need to be pulled apart and secured individually, which is inefficient and can damage cable insulation.
Innovation Solution
A compact, triangular-section clamp design with paired clamping jaws and rubber inserts that allows for simultaneous strain relief of three power cables, featuring adjustable fastening means and a robust structure for secure fixation, enabling easy assembly and protection of cable insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are secured individually with separate clamps, then each cable is firmly fixed, but assembly space and work requirements increase significantly
Solution Approach 1:
The patent combines multiple individual cable clamps into a single integrated clamp structure that can simultaneously secure multiple cables (typically three) in a bundled configuration. This merging eliminates the need for separate clamps for each cable, reducing assembly complexity and space requirements while maintaining reliable fixation for each cable through the integrated clamping mechanism.
2Ease of operation
If cables are pulled apart during assembly, then individual clamps can be applied, but assembly space and time requirements increase
Solution Approach 1:
The clamp is designed with pre-formed cable passages and clamping surfaces that are ready to receive bundled cables in their natural configuration. The cables do not need to be pulled apart or repositioned; they can be inserted directly into the clamp in a bundled state, and the clamping action is then applied to secure all cables simultaneously, significantly reducing assembly time and effort.
3Adaptability or versatility
If rounded wire clamping elements are used, then pipe attachment is enabled, but cable insulation is damaged due to surface loading
Solution Approach 1:
The clamp incorporates specifically designed clamping surfaces with appropriate material properties and geometric characteristics that distribute the clamping force evenly across the cable surfaces. These localized clamping zones are engineered to prevent concentration of stress that could damage cable insulation, while still providing secure attachment. The clamping surfaces may feature rounded contours or cushioning materials adapted to the cable geometry.
4Productivity
If bracing surfaces run in a line, then thin cables can be secured, but clamping force is insufficient for high-voltage cables
Solution Approach 1:
The clamp transitions from a linear arrangement of clamping surfaces to a two-dimensional or three-dimensional clamping configuration. The clamping surfaces are arranged in multiple planes and orientations that wrap around or enclose the bundled cables, distributing the clamping force across a larger surface area. This dimensional expansion of the clamping mechanism provides sufficient force for thick high-voltage cables while maintaining the ability to accommodate thinner cables.

AI summary
A cable clamp (2) for holding cables, preferably high-voltage cables, comprises an elongated clamping body (2) for receiving the cables. The elongated clamping body (2), which is provided with three cable entry channels (3a, 3b, 3c), has at least a lower part (2a), a middle part (2a), and an upper part (2c), each of which forms pairs of clamping jaws (4a, 4b and 4c, 4d, respectively) for fixing the cables (1a, 1b, 1c) in the cable entry channels (3a, 3b, 3c) of the clamping body. This results in a compact, space-saving design for the cable clamp (2), which simultaneously ensures a completely tensile-resistant fixation of the power cables.
