According to the technical scheme, the first clamping piece and the second clamping piece are fixedly clamped on the pin type outlet pressing plate through the transition section, the contact pin in the middle of the first clamping piece and the second clamping piece is inserted into the pin type outlet pressing plate, the experimental wire is connected into the experimental wire connecting hole at the tail end of the first clamping piece, the current signal of the experimental wire flows to the contact pin through the metal conducting wire in the experimental wire connecting hole at the tail end of the first clamping piece, and then flows into the pin type outlet pressing plate through the contact pin.
Furthermore, a stretching structure is arranged in the transition section, and the first clamping piece and the second clamping piece are clamped through the stretching structure. The spring is positioned on one side of the metal wire. The stretching structure is a stretched deformed spring. Through the tensile deformation of the spring that sets up in the changeover portion, first, second clamping piece can the fixed clamp tightly on the clamp plate.
Furthermore, the depth of the experimental wiring hole is matched with the length of the experimental connector lug. The metal conducting wire is positioned at the bottom of the experiment line connecting hole. The first clamping piece, the second clamping piece and the transition section are made of insulating materials. The metal wire is arranged at the bottom of the experiment wire connecting hole, so that the experiment wire inserted into the experiment wire connecting hole can be connected with the metal wire, and the current of the experiment wire flows through the metal wire and then flows to the contact pin connected with the metal wire. The first clamping piece, the second clamping piece and the transition section are made of insulating materials, and the electric leakage risk of the experiment clamp in the experiment work is reduced.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, the contact pin is arranged between the first clamping piece and the second clamping piece of the experiment clamp, so that the contact pin can be in perfect contact without damaging the socket; the signal current of the experimental wire flows to the contact pin through the experimental wire connecting hole and the metal lead which are arranged at the tail end of the first clamping piece of the experimental clamp; the first clamping piece and the second clamping piece are clamped and fixed on the pin type outlet pressing plate through the arrangement of the stretching structure, so that the contact pin cannot easily slide off the socket in the test process.
