Abstract
Abstract 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A terminal device for making an electrical connection to a device under test, comprising: an insulating housing; a first electroconductive pin being slidably inserted into said insulating housing, said first electroconductive pin including a hook-shaped terminal section provided at one end of said first electroconductive pin, and said first electroconductive pin being urged by a spring in such a direction that said hook-shaped terminal section is retracted towards one end of said insulating housing; a fixed electrical conductive terminal located at said one end of said insulating housing to oppose an inner surface of said hook-shaped terminal section; a pusher slidably located at another end of said insulating housing for anchoring said first electroconductive pin; and a pair of lead wires being respectively connected to said first electroconductive pin and said fixed terminal at another end of said insulating housing.
Claim 2
Dependent Claim
140 words
A terminal device for making an electrical connection to a device under test, comprising: an insulating housing; a first electroconductive pin being slidably inserted into said insulating housing, said first electroconductive pin including a hook-shaped terminal section provided at one end of said first electroconductive pin, and said first electroconductive pin being urged by a spring in such a direction that said hook-shaped terminal section is retracted towards one end of said insulating housing; a fixed electrical conductive terminal located at said one end of said insulating housing to oppose an inner surface of said hook-shaped terminal section; a pusher slidably located at another end of said insulating housing for anchoring said first electroconductive pin; and a pair of lead wires being respectively connected to said first electroconductive pin and said fixed terminal at another end of said insulating housing.
Claim 3
Dependent Claim
57 words
A terminal device for an electrical connection as recited in claim 1, wherein said insulating housing further includes a flange disposed at an outer surface of said insulating housing for providing a finger contact surface to apply a manual force to said spring for moving said hook-shaped terminal away from said one end of said insulating housing.
Claim 4
Dependent Claim
40 words
A terminal device for an electrical connection as recited in claim 1, wherein said fixed terminal further comprises a second electroconductive pin extending from an inside of said insulating housing to oppose the inner surface of said hook-shaped terminal section.
Claim 5
Dependent Claim
23 words
A terminal device for an electrical connection as recited in claim 3, wherein said second electroconductive pin is embedded within said insulating housing.
Claim 6
Dependent Claim
49 words
A terminal device for an electrical connection as recited in claim 1, wherein said fixed terminal further comprises an electroconductive cylinder, said insulating housing surrounding said electroconductive cylinder except for a portion of said electroconductive cylinder serving as said fixed terminal, said electroconductive pin being disposed in said cylinder.
Claim 7
Dependent Claim
32 words
A terminal device for an electrical connection as recited in claim 5, further comprising a cylinder of insulting material extending through the inside of said electroconductive cylinder to form a coaxial structure.
