A mobile terminal transmission line electrical performance testing device

Abstract

The invention provides an electrical performance test device for a mobile-terminal transmission line. The electrical performance test device comprises a test jig, an electrical test instrument electrically connected with the test jig, and a test terminal connected to the test jig, wherein an interface used for connecting the transmission line to be detected and a data interface used for connecting the test terminal are formed in the test jig; the test jig is mainly formed by electrically connecting a first test module and a second test module; the first test module is electrically connected with the electrical test instrument; the second test module is electrically connected with the test terminal. The electrical performance test device provided by the invention has the functions of being capable of rapidly and accurately detecting whether the mobile-terminal transmission line has open-circuit, short-circuit and staggering, and whether the mobile terminal is charged and the like, thus improving the detection efficiency for the transmission line, and saving labour and working hours.

Description

Problems solved by technology

[0003] Electronic digital accessories refer to the directly related accessories used in the use of digital products, which is what we call digital secondary products. Data transmission lines are one of them. At present, with the surge in the supply pressure of data transmission lines, many manufacturers Production has brought new challenges. How to quickly and accurately detect whether the produced data transmission line is qualified has become one of the problems that restrict production efficiency. In the existing detection method, the data transmission line to be tested is directly inserted into the computer, through The computer simulates the input signal, and then the other end is inserted into the production detector, and the data displayed by the computer is used to detect and determine whether the product has defects such as open circuit, short circuit, misalignment, etc., so as to determine whether the product is qualified; this method has many defects: (1) The detection efficiency is low and the operation is inconvenient; (2) the production cost is too high, a large amount of equipment resources and power resources are wasted, and the computer is inconvenient to repair; (3) the computer volume occupies a large amount of working space in the production line, affecting production operations, And accidents may occur due to improper operation of the operator. In addition, if you want to test whether the transmission line is charged normally, you need to use other detection devices to achieve it. This will cause the test process of the transmission line to take too long, affect the test efficiency, and A lot of labor costs will also be wasted, and other accidents may occur during the connection of the test steps of the two test fixtures

Although this method can realize accurate inspection of the needle bed of the fixture, and accurately reflect the contact condition between the test needle on the fixture and the circuit board under test through the contact resistance measurement, its computer volume occupies a large amount of work space in the production line, affecting production operations. And accidents may occur due to improper operation of the operator
