Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The embodiment of the utility model discloses SSPC solid state power controller test fixture, it is shown with reference to fig. 1 to 2 to refer to, including backplate, integrated circuit board power supply ware, test fixture voltage input ware, PC end interface, backplate output terminal, load.

The back plate is used for installing components such as an SSPC solid-state power controller, a connecting board power supply, a test tool voltage input device, a PC end interface, a back plate output terminal and the like. The utility model discloses the backplate specifically can be VPX connector assembly, and SSPC solid state power controller passes through the public female head of VPX connector with the backplate and is connected. The backboard is also electrically connected with the board card power supply and the test tool voltage input device. The integrated circuit board power supply ware is to the power supply such as main chip, communication module on the SSPC integrated circuit board, the utility model discloses the integrated circuit board power supply ware of embodiment can be a 5V's DC power supply. The testing tool voltage input device loads a testing voltage to the SSPC solid-state power controller through a wiring line on the backboard, and the specific voltage value depends on the product protection voltage value. And a backboard output terminal is also connected to the backboard and serves as an output wiring terminal of the SSPC solid-state power controller, and the rear end of the backboard output terminal is connected with a load.
