Embodiment 1

[0034] See attached figure 1 with 2 , a portable multi-interface video cable test box, which is a box structure, including an upper box and a lower box, and the two parts are connected by a box connecting member 8 to realize the opening and closing of the box.

[0035] A display screen 2 is embedded in the upper cabinet, and the display screen has a DVI interface.

[0036] The lower box body is the test box host, including a controller, a first signal conversion module, a second signal conversion module, a power supply module, and a switch button 7 and a test button 6 . The controller has a DVI interface, and the controller is connected to the DVI interface of the first signal conversion module through a DVI cable. The function of the first signal conversion module is to convert the DVI signal output by the controller into HDMI, SDI, DVI, VGA, 5BNC signal, and the first signal conversion module provides HDMI male, SDI male, DVI male, VGA male, 5BNC male, HDMI female, SDI fem...

Embodiment 2

[0044] Further, in order to adapt to the test of short wires and adapters, the cable connector provided by the test box is a retractable connector 11, which contains a spring tension mechanism, which can be pulled out to extend the connector.

Embodiment 3

[0046] Further, the box body is made of metal anti-interference material. The upper box body and the lower box body are provided with handles 1 respectively.

Abstract

The invention discloses a portable multi-interface video cable test box. A display, a controller, a first signal conversion module, a second signal conversion module and an operation panel are arranged in the box body. The operation panel is provided with ten input interfaces and ten output interfaces. The ten input interfaces are connected with the controller through the first signal conversion module. The ten output interfaces are connected with the displayer through the second signal conversion module. A test video is stored in the controller. During testing, one end of a cable to be testedis inserted into one input interface, and the other end of the cable to be tested is inserted into one output interface. The quality of the cable to be tested can be judged by observing the display state of the display screen.

Description

technical field [0001] The invention belongs to the technical field of communication testing, in particular to a portable multi-interface video cable testing box. Background technique [0002] With the popularization and use of the video conferencing system of the State Grid Corporation of China, the number of video equipment in the venue is increasing. The signal input and output connectors of different video equipment are often different from each other, which requires the use of video signal cables with various connector types. Commonly used video cable connectors include VGA, DVI, 5BNC, SDI, HDMI, etc. Each connector is divided into male and female connectors, a total of 10 connectors. Based on two connectors per video cable, a total of 55 video cables can be combined. How to conveniently test the usability of each cable has become an urgent problem to be solved. At present, there are two commonly used methods for testing video cables: one method is to observe whether ...
