Abstract

The invention relates to the technical field of tantalum electrolytic capacitors, and discloses a test fixture for chip tantalum electrolytic capacitors, which includes an upper template, a middle template, a lower template, a negative electrode press pin, an insulating base, a positive electrode press pin, a circuit board, a hydraulic oil cylinder, and a pressure pin. Needle positioning plate and positive needle pressing panel, the lower surface of the middle template is provided with multiple buffer grooves, the negative electrode pressing needle is slidingly connected with the groove wall of the buffer groove, the upper end of the negative electrode pressing needle is fixedly connected with a telescopic rod, and the upper end of the telescopic rod is fixedly connected There is a first piston, and the same compression spring is fixedly connected between the first piston and the negative electrode indenter. The compression spring is movably sleeved on the rod wall of the telescopic rod. The groove wall of the buffer groove is symmetrically provided with two sliding grooves. The sliding connection has a second piston. The chip-type tantalum electrolytic capacitor test fixture can perform multi-stage buffering on the negative electrode pressure needle, avoiding damage to the circuit board caused by the negative electrode pressure, effectively reducing the wear of the guide post and the guide sleeve, and improving the service life of the fixture.

Description

technical field [0001] The invention relates to the technical field of production of tantalum electrolytic capacitors, in particular to a test fixture for chip-type tantalum electrolytic capacitors. Background technique [0002] Tantalum electrolytic capacitors were first successfully developed by Baylor Laboratories in the United States. Its performance is excellent, and it is the product with the smallest volume and the largest capacitance among all capacitors. Tantalum electrolytic capacitors are not only widely used in military communications, aerospace and other fields, but also widely used in industrial control, video equipment, communication instruments and other products. Tantalum electrolytic capacitors need to be tested after production, and the test requires the use of fixtures for positioning. [0003] After searching, the Chinese patent authorization number is CN202533462U patent, which discloses a chip tantalum electrolytic capacitor test fixture, including up...
