Angled EV Charging Gun Connector to Keep Cables Off the Road
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging guns for electric vehicles often result in charging cables hanging down onto the road when charging left-drive vehicles, posing a danger to passersby due to inconsistent placement of charging holes and design limitations.
Innovation Solution
A charging gun with a charging connector featuring an insertion portion and a turning portion at an angle of 90 to 100 degrees, along with a parallel-wired charging cable, optionally equipped with light-emitting elements and magnetic elements to minimize the gap between the cable and the vehicle body, preventing the cable from hanging down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging connector uses a conventional design with the charging cable connected directly to the insertion portion, then the structure is simple, but the charging cable hangs down onto the road when charging left-drive vehicles, causing danger to passersby
Solution Approach 1:
The charging connector is divided into two functional parts: the insertion portion that connects to the vehicle and the turning portion that changes the cable direction. This segmentation allows the cable to be routed away from the road surface, eliminating the safety hazard while maintaining structural clarity.
Solution Approach 2:
The turning portion introduces a spatial dimension change by extending perpendicular to the insertion portion, redirecting the charging cable from a downward trajectory to a horizontal or upward path that clears the road surface and ensures passerby safety.
2Ease of operation
If the charging hole is arranged on the left side of the vehicle body for left-drive vehicles, then the charging location matches the vehicle design, but the charging cable hangs down onto the road, causing danger to passersby
Solution Approach 1:
The turning portion acts as an intermediary element between the insertion portion and the charging cable, mediating the cable's path to prevent it from hanging down onto the road while still allowing the charging hole to be positioned on the left side of the vehicle for ease of operation.
3Reliability
If the included angle between the insertion portion and turning portion is exactly 90 degrees, then the manufacturing is simple, but the cable may still have excessive gap from the vehicle body
Solution Approach 1:
The included angle is specified as a range (90-100 degrees) rather than a fixed value, allowing manufacturing flexibility while ensuring the cable maintains sufficient proximity to the vehicle body. This parameter optimization balances manufacturing ease with cable position stability.

AI summary
A charging gun for charging an electric vehicle including a charging connector and a charging cable is provided. The charging connector has an insertion portion and a turning portion connected to the insertion portion, and an included angle between the insertion portion and the turning portion is greater than or equal to 90 degrees and less than or equal to 100 degrees. The charging cable is connected to the turning portion, and the charging cable includes a plurality of wires arranged in parallel in one direction, to avoid the problem that the charging cable hangs down onto the road and causes danger to passersby.
