Problems solved by technology

However, its disadvantages are: on the one hand, during operation, it is necessary to move the electrical contact plate to the position where it fits with the end face of the product fixing seat, and then fix the electrical contact plate so that the electrical contact terminal group on the electrical contact plate Electrically connect with the interface of the electronic product, and then electrically connect the signal interface device with the test equipment to complete an aging test of the electronic product
The process is cumbersome to operate, and during use, the electrical contact plate is easily damaged due to repeated sliding back and forth, resulting in poor contact or inaccurate positioning, thereby reducing the efficiency of the aging test; on the other hand, before the aging test of electronic products, the fixture It is still necessary to connect the electronic load, and the structure of the jig is complicated, which is not conducive to production and processing

Abstract

The invention relates to the technical field of ageing tests, particularly relates to a jig for aging tests, and structurally comprises a base and an upper cover arranged above the base. The base is provided with a base printed circuit board (PCB) which is provided with a direct current (DC) signal connecting device, a product placing groove is arranged on the inner surface of the base opposite to the upper cover, and a DC signal interface is arranged in the produce placing groove and electrically connected with the DC signal connecting device through the base PCB. An upper cover PCB is arranged in the upper cover and provided with an alternating current (AC) signal connecting device, and the AC signal connecting device is electrically connected with an AC signal interface. The jig for aging tests has the advantages of being simple in structure, simple and rapid to operate and high in aging testing efficiency, and particularly meets requirements for rapid development of modern enterprises.

Description

technical field [0001] The invention relates to the technical field of aging testing, in particular to an aging testing jig. Background technique [0002] With the development of society, people have higher and higher requirements on the quality of electronic products. In order to improve the quality of electronic products, a series of aging tests need to be carried out on electronic products before leaving the factory. In the prior art, when performing aging tests on electronic products, a single electrical connection test is performed on electronic products, but the efficiency of this single product testing method is very low; on the other hand, during aging tests on electronic products, it is often necessary to For the aging test of multiple items such as light aging and damp heat aging, the interface of the electronic product needs to be electrically connected with different test equipment. Affect the service life of electronic products. [0003] In order to solve the ...
