Terminal device for electrical connection

摘要

This invention provides a terminal device for electrical connection to a lead section to be measured. The LCR measurement is easily and accurately taken with a single operation even when a space between lead sections to be measured is narrow. Thereby, an efficiency of the LCR measurement with the Kelvin connection is enhanced. An electroconductive pin is slidably inserted into a fine insulating housing. A hook-shaped terminal section is formed at the tip of the electroconductive pin. The electroconductive pin is urged by a spring in such a direction that the hook-shaped terminal section is retracted into the insulating housing and a lead section to be measured is engaged by the hook-shaped terminal section and a fixed terminal. The fixed terminal is provided at the tip of the insulating case so as to oppose the inner surface of the hook-shaped terminal portion. Two lead wires are respectively connected to the electroconductive pin and the fixed terminal at the rear end of the insulating housing.
