Description

Technical Field

[0001] The utility model relates to a testing device, in particular to a capacitor pin testing device, belonging to the technical field of capacitor pin testing. Background Art

[0002] Capacitors, or capacitors for short, are electronic components that can store electric charge. The working principle of capacitors is to store electric energy by storing electric charge on electrodes. In an electric field, electric charge will move under the action of force. When a medium is added between two conductors, the movement of electric charge will be hindered, and thus accumulate on the conductor to form capacitance. The amount of stored charge determines the capacitance value of the capacitor. Capacitors are widely used in electronic devices, and their application fields include electronics, communications, electricity and many other fields.

[0003] The capacitor pin is the part that connects the capacitor to the external circuit. Ordinary capacitors are generally provided with two pins, which are fixed to the capacitor by welding. After the pins are fixed, the capacitor pins need to be tested. The test includes electrical test and mechanical property test. Among them, the mechanical property test is mostly completed by manual spot check by the staff. In the process of pulling the pins, the control of the pulling force is not accurate enough, and it is impossible to accurately judge whether the tensile performance of the pins meets the standard. Therefore, a capacitor pin testing device is proposed. Utility Model Content
