Adjustable Cable Clamp Assembly for Varying Cable Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable clamping devices are not adaptable to varying cable diameters, leading to gaps between parts when the cable diameter exceeds the passage size, causing potential breakage and difficulty in tightening, requiring a specific device for each cable type.
Innovation Solution
A cable clamping device with a first and second part featuring inclined contact surfaces and oblong openings, allowing assembly in multiple positions to accommodate different cable diameters, with fixation members like screws and optional support metal sheets for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size passage is used in the clamping device, then the device structure is simple, but it cannot accommodate cables with different diameters, requiring multiple devices for different cable types
Solution Approach 1:
The passage is designed with movable walls that can slide relative to each other, transforming the fixed passage into a dynamic, adjustable passage. This allows the passage dimensions to change according to the cable diameter being clamped, enabling a single device to accommodate multiple cable sizes without increasing overall device complexity
Solution Approach 2:
The passage dimensions are made variable through the sliding wall mechanism, allowing the physical parameters (width, height) of the passage to be changed to match different cable diameters. This parameter adaptability eliminates the need for multiple fixed-size devices
2Ease of operation
If the cable diameter is larger than the passage size, then a gap appears between the clamping parts, but this causes difficulty in tightening and potential breakage during assembly
Solution Approach 1:
The sliding wall mechanism dynamically adjusts the passage size to match the cable diameter, eliminating gaps between clamping parts. This ensures proper contact and distribution of tightening forces, making assembly easier and preventing part breakage
Solution Approach 2:
The passage is pre-adjusted to the appropriate size before the cable is inserted and before tightening begins. This preliminary sizing action prevents gaps from forming during the tightening process, eliminating the risk of breakage and easing the operation

AI summary
The cable clamping device (10) comprises first (14) and a second (16) parts comprising first openings (26) and second openings (28) respectively, and fixation members (30) passing through the openings. The parts (14, 16) delimit together passages for cables (12), the passages extending along an axis (X). The parts (14, 16) comprise complementary inclined contact surface (22, 24), inclined with respect to the axis (X). At least one of the first (26) and second (28) openings is oblong, so that the first (14) and second (16) parts can be assembled in several different positions while the first (22) and second (24) inclined contact surfaces are on contact with each other.
