- magnetic lines of force are also formed outside the outermost first through hole 442 or the second through hole 444 to create an environment similar to the center. However, if the magnetic lines of force are formed without forming the third through hole 445 , the lines of magnetic force may be distorted while passing through the conductive plate 440 .
- the third through hole 445 serves as a passage through which lines of magnetic force pass without being distorted, thereby preventing distortion of lines of magnetic force.
- the third through hole 445 may be formed, and as shown in FIG. 9 , the third elastic matrix 446 and the plurality of third conductive particles 447 are included in the third through hole 445.
- a third conductive portion 448 may be formed.
- the third conductive part 448 is formed by magnetic force lines passing through the first through hole 442 or the second through hole 444 at the center of the conductive plate 440 and the first through hole 442 or the second through hole at the outermost part. It serves to further reduce the non-uniformity between the lines of force passing through the holes 444.
- the third elastic matrix 446 may be formed of various types of polymer materials.
- the third conductive particles 447 are arranged in the longitudinal direction of the third elastic matrix 446 .
- the third conductive particles 447 may be formed of various types of magnetic conductive particles.

Abstract
La présente invention concerne une prise de test servant à mesurer des caractéristiques électriques d'un dispositif électrique. La présente invention utilise une prise de test permettant une protection contre la perte de signaux et disposée entre des bornes en regard de connexion électrique. La prise de test se caractérise en ce qu'elle comprend : une pluralité de premières parties conductrices, comportant une première matrice élastique sous forme de colonne, dont les deux extrémités sont en contact avec des bornes d'alimentation ou de signaux en regard ; et une pluralité de premières particules conductrices agencées, à l'intérieur de la première matrice élastique, selon la direction longitudinale de la première matrice élastique ; une pluralité de supports isolants, conçus pour entourer au moins l'une des parties de la pluralité de premières parties conductrices ; et une seconde partie conductrice, entourant la pluralité de supports isolants et dont les deux surfaces sont en contact avec une pluralité de bornes de terre en regard. Dans la prise de test permettant la protection contre la perte de signaux selon la présente invention, la perte de signaux est réduite autant que possible. La vitesse et la précision d'inspection augmentent donc.
