Abstract

The invention discloses a crystal oscillator oscillation test fixture, relates to the field of electronic communication, and aims to solve the current technical problems of extremely difficult oscillation test of crystal oscillators, low batch oscillation test efficiency, high cost and the like. The crystal oscillator oscillation test fixture consists of a positioning plate (1), a pressing plate (2), a base plate (3) and a connecting piece, wherein tested crystal oscillators (4) are arranged between the positioning plate (1) arranged on an upper part and the base plate (3) arranged on a lower part; the pressing plate (2) is arranged below the base plate (3); the positioning plate (1), the pressing plate (2) and the base plate (3) are fixedly connected by several groups of connecting pieces; each group of connecting piece consists of a screw (5) and a nut (6); the screw (5) passes through corresponding holes in the positioning plate (1), the pressing plate (2) and the base plate (3) to be connected with the nut (6) on the positioning plate (1); and the positioning plate (1) is provided with openings matched with an crystal oscillator pins (7) of the tested crystal oscillators (4). The fixture is suitable to be used in crystal oscillator oscillation tests.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a crystal vibration test fixture for crystal vibration detection. Background technique [0002] There are many types of crystal oscillators (referred to as crystal oscillators), most of which are produced by professional manufacturers. At present, there are not many domestic manufacturers, and most of the crystal oscillators used in the electronics industry are imported, so they are expensive. For the expensive crystal oscillator, whether its quality meets the needs of the product needs to be verified. Many electronic products are subjected to vibration tests to verify whether they are stable and reliable during transportation and production use. In work practice, the phenomenon that the crystal oscillator does not work after the product vibration test often occurs. For more complex products, once the poor quality crystal oscillator is installed on the machine and fails...
