Detection device of universal serial bus ports

Abstract

The invention discloses a detection device of universal serial bus ports. The detection device comprises a circuit board, a universal serial bus concentrator, a management controller and a control interface. The universal serial bus concentrator, the management controller and the control interface are all electrically arranged on the circuit board. The management controller is used for controlling the universal serial bus concentrator to detect in an automated manner. The control interface serves as an input-output interface of the circuit board and utilizes high-low electric potential of an output signal to control and drive a relay such that a normally open contact and a common contact form a short circuit to perform a simulation test of a button to be pressed and such that a normally closed contact and the common contact form a short circuit to perform a simulation test of the button to be released. The detection device of the universal serial bus ports can control the universal serial bus concentrator in an automated manner to detect universal serial bus ports such that manpower for conventional hand-operated detection and damage rate of detection tools are greatly decreased.

Description

technical field [0001] The present invention relates to a detection device, in particular to a universal serial bus port detection device. Background technique [0002] Generally speaking, electronic products need to go through a certain testing process during production to ensure that each function of the electronic product can operate normally. Specifically, the inspection items of electronic products can be divided into automatic inspection and manual inspection. The automatic inspection can connect the electronic product to a computer device to automatically perform the inspection, while the manual inspection requires the operator to perform the inspection manually. [0003] For example, the detection of a plurality of Universal Serial Bus (USB) ports on an electronic product usually requires an operator to manually detect by constantly plugging and unplugging the Universal Serial Bus ports with a detection jig. However, such The detection method is not only slow in det...

[0003] For example, the detection of a plurality of Universal Serial Bus (USB) ports on an electronic product usually requires an operator to manually detect by constantly plugging and unplugging the Universal Serial Bus ports with a detection jig. However, such The detection method is not only slow in detection speed, but also may cause damage to the detection fixture due to continuous plugging and unplugging of the detection fixture

[0004] Therefore, how to design a universal serial bus port detection device under the premise of taking into account the detection speed and detection fixture maintenance can be said to be a big challenge
