  • Publication number: 20150061716
    Abstract: A testing finger (1) comprises a finger-shaped rod (2). A sharp end (3) of the finger-shaped rod (2) is connected with a testing part used for measuring a distance. The testing part is a group of testing heads, and the length of each testing head corresponds to minimum safe distances at different voltage levels in intrusion protection. The testing part is connected with the sharp end (3) of the finger-shaped rod (2) in a detachable insertion manner. The testing finger (1) can accurately determine whether the distance between a live part or a live lead which is not insulated in an electrical device and a protective part is greater than or equal to a minimum safety distance, thereby solving the problem in the prior art that the distance between the sharp end (3) of the finger-shaped rod (2) and the live part or the live lead cannot be accurately measured by a clamp in a situation of limited space.

  • Patent number: 8591805
    Abstract: The present invention is a silver alloy suitable for use in a probe pin made of an Ag-Cu alloy, wherein the silver alloy comprises 30 to 50% by weight of Cu and Ag as balance. This silver alloy further comprises 2 to 10% by weight of Ni to further improve strength. A probe pin made of these materials has stable contact resistance even under low contact pressure. The probe pin has excellent strength and antifouling property to adhesion of a foreign matter from a contact object due to repetitive use. Thereby, the probe pin usable in a stable manner for a long period of time can be obtained.
