Offset Cable Clamp for Adjustable Power Cable Wedging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical power supply devices lack the ability to adjust the length of the electrical power cable between the housing and the electromechanical actuator, leading to potential damage and stress on the cable due to fixed clamping mechanisms.
Innovation Solution
The device incorporates a cable clamp with offset orifices that allow for adjustable cable length by wedging the power cable in a pressed position and releasing it in a tilted position, ensuring secure fixation without internal intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable clamp uses a fixed clamping mechanism with aligned orifices, then the cable is securely held in position, but the cable length cannot be adjusted and the cable may be damaged due to fixed positioning
Solution Approach 1:
The cable clamp employs asymmetric offset orifices where the first orifice in the cable clamp is deliberately misaligned relative to the second orifice in the housing. This asymmetric arrangement creates a wedging action that enables both secure cable fixation and adjustable cable length, resolving the contradiction between reliability and adaptability.
2Reliability
If the cable clamp is fixed tightly to the housing, then the cable is securely clamped, but internal components may be damaged due to lack of installation flexibility
Solution Approach 1:
The cable clamp incorporates a tilting mechanism that allows dynamic adjustment during installation. The clamp can be tilted relative to the housing to enable cable insertion and length adjustment, then fixed in the pressed position for secure clamping. This dynamic capability resolves the contradiction between clamping reliability and installation flexibility.
3Ease of manufacture
If the cable clamp structure is simplified with aligned orifices, then the manufacturing is easier, but the cable cannot be adjusted and may experience stress
Solution Approach 1:
The offset orifice configuration, while slightly more complex than aligned orifices, provides a practical solution by enabling cable adjustment capability. The asymmetric design prevents cable stress and damage by allowing proper cable routing and length adjustment, outweighing the minor increase in manufacturing complexity.

Function Achieved in This Case
Enables adjustable and secure cable length adjustment without damaging internal components, reducing stress on the cable and ensuring robust fixation while allowing easy installation.
Implementation Method 1
the electrical power cable is held in position by wedging by means of at least a portion of a first peripheral surface of the first passage orifice and at least a portion of a second peripheral surface of the second passage orifice

AI summary
An electrical power supply device (31) comprises a housing (48), a cable (18) and a cable clamp (49). The cable clamp (49) comprises a first hole (51) for the cable (18) to pass through. The housing (48) comprises a second hole (52) for the cable (18) to pass through. In a pressed position of the cable clamp (49) against the housing (48), in which a fixing screw (50) is screwed, a first geometric center (C51) of the first hole (51) is offset relative to a second geometric center (C52) of the second hole (52), so that the cable (18) is held in position by wedging. Furthermore, in a tilted position of the cable clamp (49) relative to the housing (48), in which the fixing screw (50) is at least partially unscrewed, the cable (18) is released relative to the cable clamp (49) and the housing (48), so that the cable (18) can be slid through the holes (51, 52).
