Rotating Charging Cable Clamp for Mid-Span Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging-cable clamps lack rotational freedom, leading to charging cables being unable to be straightened and winding into circles, which can cause damage to the cable and charging gun.
Innovation Solution
A movable charging-cable clamp with a clamping component and pivot component, featuring an annular structure that allows rotational freedom around the central axis, preventing the cable from being straightened and wound into a circle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging cable is fixed rigidly by the clamp, then the cable is supported at a middle point, but the cable cannot be straightened and winds into circles causing damage
Solution Approach 1:
The clamp structure is transformed from a rigid fixed state to a dynamic movable state. The clamp body can slide along the charging cable within the guide groove, and the clamping block can move along the clamping groove, allowing the clamp to adapt its position dynamically. This enables the cable to be straightened while maintaining support stability.
Solution Approach 2:
The clamp is divided into multiple independent components: clamp body, clamping block, guide groove, and clamping groove. This segmentation allows each component to move independently, providing degrees of freedom for the cable to be straightened while maintaining support function.
2Ease of operation
If the clamp structure is made movable with guide grooves, then the cable can be straightened, but the device complexity increases
Solution Approach 1:
The clamp is divided into modular components (clamp body, clamping block, grooves) that can move independently. This segmentation provides the necessary degrees of freedom for cable straightening while keeping each component relatively simple in structure.
Solution Approach 2:
The guide groove and clamping groove act as intermediary elements that guide the movement of the clamping block and clamp body respectively. These intermediary structures enable complex motion patterns while maintaining simple individual component designs.

AI summary
A movable charging-cable clamp (1, 1a, 1b) is disclosed and includes a clamping component (10, 10a) and a pivot component (20, 20a, 20b). The clamping component (10, 10a) is configured to be fixed on an outer peripheral surface (90) of a charging cable (9). The clamping component (10, 10a) includes a first guide groove (13), which is recessed and disposed around an outer peripheral wall of the clamping component (10, 10a), and is centered at a central axis (C) of the charging cable (9). The pivot component (20, 20a, 20b) includes an annular structure (21, 21a) and a hanging part (23). The annular structure (23) is fitted onto the first guide groove (13) and allows the clamping component (10, 10a) and the charging cable (9) to rotate relative to the pivot component (20, 20a, 20b) around the central axis (C). The hanging portion (23) is disposed adjacent to an outer periphery of the annular structure (21, 21a). The annular structure (21, 21a) provides the charging cable (9) with a degree of freedom of rotation in the axial direction, so as to achieve a middle support point of the charging cable (9).
