Accompanying drawing explanation
Fig. 1 is the schematic diagram of the test device of test cable break-make of the present utility model and correctness.
In figure: 1 first connector socket, 2 second connector sockets, 3 master controllers, 4 bleeder circuits, 5 LED lights, 6 lithiums
Battery is powered and charging circuit.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, give the schematic diagram of the test device of test cable break-make of the present utility model and correctness, its
By first connector socket the 1, second connector socket 2, master controller 3, bleeder circuit 4, LED light 5 and lithium battery power supply and
Charging circuit 6 forms, and the first shown connector socket 1 and the second connector socket 2 are provided with some terminals, line to be tested
The plug at cable two ends is connected on the first connector socket 1 and the second connector socket 2 respectively.Bleeder circuit 4 is formed by resistant series, electricity
Bleeder circuit 4 one end that resistance series connection is formed is connected to power supply on the ground, and the other end is connected to 12V positive source；On first connector socket 1
Terminals are connected between the corresponding resistor of bleeder circuit 4 respectively, so that different terminals have fixed voltage.
The terminals of the second connector socket 2 A/D ports different from master controller 3 respectively are connected, in order to master controller
Gather the magnitude of voltage of each terminals on the second connector socket 2.The quantity of LED light 5 and the number of terminals on connector socket
Measure equal, in order to whether conducting and line sequence to every cable to be tested are normally carried out instruction.Shown lithium battery power supply and
The work that charging circuit 6 is whole test device provides stable electric energy.
Series resistance in bleeder circuit 4 makes the voltage between each two resistance different, and each magnitude of voltage is fixing
So that on the first connector socket 1, each terminal voltage is gradually successively decreased, until 0.When the first connector socket 1 connects with second
Connecting cable to be measured between line socket 2, the A/D interface of master controller 3 now can read the magnitude of voltage conducted by cable.
