Function of inner three-speed thimble spring

Spring thimble, also known as probe, is the contact medium of electrical test and the high-end precision electronic hardware component. When tested as a circuit board, it is divided into spring pins and general pins. When using the spring needle, it is necessary to make a test mold according to the wiring situation of the tested circuit board. Usually, only one circuit board can be tested by one mold. When using universal pins, only enough points are needed to test the circuit board, so most spring thimbles manufacturers will produce different types of spring thimbles at present. The surface of the spring needle is plated with a layer of gold, which improves its corrosion resistance, mechanical properties and electrical properties. Spring needle is widely used in aviation, aerospace, military communication, military electronics and other fields because of its small size, high precision and light weight. Secondly, it also involves cars, car navigation and other fields that are inseparable from us; In addition, medical equipment, wireless equipment, data communication equipment, etc. It also exists.
