Description of the Related Art In a conventional probe pin, a plunger is slidably inserted in a barrel, a tip of the plunger is projected from an opening of the barrel, and a spring inserted between a distal end of the plunger and a bottom surface of the barrel is used. It was giving the plunger the force to project from the barrel. In addition, the plunger is pushed into the barrel until the distal end of the plunger abuts the bottom surface of the barrel by pressing the tip, or the coil of the spring comes into close contact and compresses, so that the entire movable range is reached. The structure is such that it operates over and connects to the opposite contact part.

う問題点があった。In the conventional probe pin, since the plunger operates over the entire movable range by pressurization, the spring in the barrel and the distal end of the plunger are rapidly worn, and the contact resistance is increased. There was a problem that the life was short.

とを特徴とする。DISCLOSURE OF THE INVENTION The present invention is a probe in which a plunger slidably inserted in a hollow barrel having an opening at one end is biased by a spring so that a tip of the plunger protrudes from the opening of the barrel. In the pin, the outer diameter of the tip of the plunger is made larger than the inner diameter of the barrel, and the tip of the plunger contacts the tip of the barrel when the plunger is pushed into the barrel. .

設定されている。In the probe pin, a plunger main body 2 which is a movable portion is inserted in a barrel 1, and a tip end portion 3 of the plunger projects from an opening of the barrel 1. A spring 4 is provided between the end of the plunger and the bottom of the barrel. The outer diameter of the plunger tip 3 is larger than the inner diameter of the barrel 1. Also, with the plunger protruding from the barrel 1, the movable range, which is the dimension from the end of the plunger 2 to the bottom surface of the barrel 1 and the dimension from the tip of the plunger 2 to the tip of the barrel 1, is A, and the plunger tip 3 Is B, the length B of the plunger tip 3 is set to 1/3 of the entire movable range A.

パー機能が働らく。In the above structure, when pressure is applied to the tip 3 of the plunger, the pressure causes the spring 4 to move.
Is compressed and the entire movable range A of the plunger 2 is 2
At the time of / 3 compression, the lower part of the plunger tip 3 hits the tip of the barrel 1, and the stopper function works to prevent further compression.

抗も安定させる効果がある。As described above, according to the present invention, the tip of the plunger hits the tip of the barrel when the tip of the plunger is thickened and the plunger is pushed into the barrel. By preventing the plunger from being pushed into the barrel, it is possible to prevent abrasion of the end portion of the plunger, prolong the life of the probe pin and stabilize the contact resistance.
