A metal terminal includes a front-side terminal member and a rear-side terminal member. The front-side terminal member includes a female connection portion, and the rear-side terminal member includes a male connection portion. The female connection portion has an insertion port in which the male connection portion is inserted. The insertion port is formed in a shape that prevents the insertion port and the male connection portion from coming into contact with each other when the male connection portion is inserted therein. The female connection portion includes a terminal contact portion which brings the male connection portion and the female connection portion into contact with each other by pressing the male connection portion toward the female connection portion inside the female connection portion.

A temperature probe for determining the temperature according to the three-point probe method includes a three-wire line several meters long consisting of a first connecting line, a second connecting line, and a third connecting line connected to sensor element. The connecting lines are made of a first material and serve to transmit energy and the measured temperature values. A conductive element made of a second material is inserted in the second connecting line and in the third connecting line. The resistivity of said second material is higher than the resistivity of the first material. The two inserted conductive elements are designed in such that the second connecting line and the third connecting have the same resistance as the first connecting line. Additionally, the present disclosure refers to a method describing the manufacture of a temperature probe.

A browser probe has a probe body including a signal line, a nose of electrical insulating material integral with and projecting from the probe body, a pin supported by the probe body and electrically conductively connected to the signal line, a spring exerting a biasing force on the pin, an electrically conductive probe tip supported by the nose at a distal end of the nose remote from the probe body, and a plurality of discrete resistors interposed between the pin and the probe tip within the nose. The resistors are supported independently of another so as to be slidable within the nose. The probe tip is electrically conductively connected to the signal line via the resistors and the pin under the biasing force exerted by the spring.
