AI Technical Summary

Technical Problem

Conventional alligator clips used with measuring instruments like voltmeters often come off from thicker wires, leading to inefficient and inaccurate measurements, especially when the wire is installed in narrow areas or has a cylindrical terminal with an insulating coating.

Method used

A measurement terminal with a conductive metal base, spiny protrusions, and a clamping portion with a concave-convex anti-slip structure, which is interposed between the wire and the alligator clip, ensuring secure connection and increased contact area, and optionally uses a fixing means like a band made of insulating elastic material.

Benefits of technology

The solution allows for reliable and easy connection of the alligator clip to the wire, improving measurement accuracy and stability, even with larger diameter wires, and reducing the risk of the clip coming off, thus enhancing the convenience and reliability of the measurement process.

Abstract

To provide a measurement terminal capable of easily and reliably performing work for connecting an alligator clip that is the connection terminal of a measuring instrument, such as a voltmeter, to an electric wire to be measured.SOLUTION: A terminal that is used while being attached to an electric wire 31 that is a stranded wire 31a and connects an alligator clip 33 of a measuring instrument comprises a base 4 made of a metal material having conductivity, multiple spiny projections 5 that are made of a metal material having conductivity and project on a surface that faces the surface of the electric wire 31 in the base 4, and a column-shaped clamping section 6 that is made of a metal material having conductivity and protrudes on a surface in a side opposite to a surface having the spiny projection 5 in the base 4. The clamping section 6 is in a measurement terminal 1A having a recessed and projecting slide stop structure 6b on its circumferential side surface.SELECTED DRAWING: Figure 3
