A pin clamping device for a capacitance detection system

Abstract

The invention, which relates to the detection field, provides a pin clamping device for a capacitance detecting system. The pin clamping device comprises a base, adjusting blocks and driving mechanisms. An adjusting slot with an upward opening is formed in the base; an adjusting mechanism is arranged at one side outside the adjusting slot; and inner cavities are formed in the adjusting blocks. Theadjusting block arranged at one side inside the adjusting slot is fixedly connected with the side wall of the adjusting slot; and the adjusting block arranged at the other side inside the adjusting slot is fixedly connected with the adjusting mechanism. Clamping mechanisms are arranged at the upper space inside the inner cavities symmetrically and the lower parts inside the inner cavities are insliding connection with linkage mechanisms; and the lower end of each clamping mechanism is movably connected with one end of each linkage mechanism. The upper ends of the driving mechanisms are movably connected with the linkage mechanisms. When the device is used for measuring the capacitance value of the capacitor, adaptability to pins with different lengths and diameters is improved; a phenomenon that the measurement operator needs to fix or loosen the capacitor by hands is avoided, so that the measurement efficiency is improved; and a phenomenon that a measurement error is caused by the contact between the hand and the capacitor pin is avoided.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to a pin clamping device of a capacitance detection system. Background technique [0002] The capacitance value of a capacitor is a physical quantity that represents the ability of a capacitor to hold charges. During the production process of a capacitor, the quality personnel of the production line generally check the capacitance value parameters of the capacitor at a certain frequency. After the capacitor is cooled by a high-temperature test, it is also necessary to measure its capacitance. value to judge whether the capacitor has passed the high temperature test. [0003] In the prior art, when measuring the capacitance value of the batch capacitor, the measuring personnel generally fix the pin of the capacitor with the input end of the measuring instrument by hand, and then perform the measurement. This method needs to be fixed by hand continuously, and then It takes a lot of ...

Problems solved by technology

[0003] In the prior art, when measuring the capacitance value of the batch capacitor, the measuring personnel generally fix the pin of the capacitor with the input end of the measuring instrument by hand, and then perform the measurement. This method needs to be fixed by hand continuously, and then It takes a lot of time and energy to loosen it by hand, and the efficiency is not high. In addition, human hands generally have static electricity and pollutants, which are prone to measurement errors after they come into contact with the capacitor pins.
