Voltage Detection Probe with Elastic Clip and Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact voltage measuring devices struggle to accurately detect voltage on insulated wires without damaging the insulator, and they often require complex attachments or suffer from reduced accuracy due to interference from clip portions.
Innovation Solution
A voltage detection probe with a clip portion that is elastically deformable, allowing it to widen and fit over the wire, and retain it with an elastic force, ensuring the electrode is securely positioned along the wire's outer surface, while also serving as a shield to reduce electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clip portion is added to retain the probe on the wire, then the probe can be securely attached, but the clip portion interferes with voltage detection accuracy
Solution Approach 1:
The harmful function of the clip portion (electromagnetic interference with voltage detection) is separated from its useful function (mechanical retention). The shield body is extracted as a distinct component that specifically addresses the interference problem, while the clip portion focuses solely on mechanical attachment without detection interference.
Solution Approach 2:
A shield body is introduced as an intermediary component between the clip portion and the wire. This shield body blocks electromagnetic interference from reaching the detection electrode, thereby protecting the voltage detection accuracy while allowing the clip portion to maintain its retention function.
2Ease of operation
If the probe structure is simplified for easy attachment, then operation becomes easier, but the probe may not securely retain on the wire
Solution Approach 1:
The clip portion is designed with elastic deformability, allowing it to dynamically adjust its shape during attachment. The user can easily attach the probe by pressing the elastic clip onto the wire, and the elastic force automatically provides secure retention without requiring complex fastening mechanisms.
3Measurement precision
If the electrode is positioned close to the wire for accurate detection, then measurement precision improves, but electromagnetic interference increases
Solution Approach 1:
The shield body serves as a protective intermediary between the wire and the detection electrode. It allows the electrode to be positioned close to the wire for accurate voltage detection while simultaneously blocking electromagnetic interference from affecting the detection process.

AI summary
A voltage detection probe includes an electrode configured to detect a voltage applied to a wire, and a clip portion freely attachable to and detachable from the wire. The clip portion has a fitting concave portion into which the wire is to be fitted, the clip portion being elastically deformable to widen an opening of the fitting concave portion. The clip portion is configured to retain, by an elastic force, the wire fitted through the opening into the fitting concave portion to cause the electrode to be disposed along an outer peripheral surface of the wire.
