Line 16 one end of running in is connected to bridge crossing plate 14, and the other end is connected to the testing host 15 being arranged on below panel by adapter
Port.Panel 10 lower left corner arranges touch-switch 17, and this touch-switch 17 is connected on the testing host below panel, logical
Crossing this touch-switch to control cylinder and move up and down, panel can also call test program by it in test process.By
In the huge number of LCM module, and there is the difference such as pin, width spaces in different types of LCM module communication interface,
Therefore, when testing different product, need to change corresponding bridge crossing plate.But, owing to testing host is mounted under testing jig
Face, and bridge crossing plate 14 face on the faceplate 10, also have air cylinder support 11 to block the most above, so when changing bridge crossing plate
And it is inconvenient, the most smoothly.Further, due to the limit in structure, between connecting test mainboard and bridge crossing plate
Line is long.Also due to the reason in structure, testing host is used for show measurement electric current, voltage, selects test module
Main display installs trouble.
Utility model content
For the deficiency in the presence of prior art, this utility model provides a kind of novel LCM module test device,
This test device is by carrying out structure improvement to the test fixture of traditional, pneumatic formula to different types of LCM module
During test, change different bridge crossing plate convenient, fast.
For achieving the above object, this utility model have employed following technical scheme:
A kind of LCM module test device, including hollow base, wherein, also includes:
Telescopic unit, it is arranged in described hollow base, and pars contractilis passes hollow base straight up；

Support, it is arranged on described hollow base, and is positioned at pressure head rear, and described support has one and accommodates chamber；
Testing host, it is arranged in the receiving chamber of described support, and is provided with test port；
Bridge crossing plate, it is arranged on described hollow base, and is positioned at below pressure head, and the side of described bridge crossing plate is provided with connection
Winding displacement, the other end of described connection winding displacement is connected to test port.
Compared to prior art, this utility model at least has the advantages that
The LCM module test device that this utility model provides is by entering the unit of traditional, pneumatic formula LCM test fixture
Go layout again so that telescopic unit is positioned at hollow base, and testing host and bridge crossing plate are arranged in hollow base
Above, so becoming convenient, quick for the replacing of bridge crossing plate.
Accompanying drawing explanation
Fig. 1 is the one of which LCM module test fixture structural representation of prior art；
Fig. 2 is that LCM module provided by the utility model tests structure drawing of device.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and act on more clear and be apparent to,
With detailed description of the invention, this utility model is further elaborated below in conjunction with the accompanying drawings:
The utility model proposes a kind of LCM module test device, including hollow base 20, the most also include: stretch
Contracting unit 21, it is arranged in described hollow base 20, and pars contractilis passes hollow base 20 straight up；Pressure head 22,
It is arranged on above described hollow base 20, and is connected on the pars contractilis of telescopic unit 21；Support 23, it is arranged on institute
Stating on hollow base 20, and be positioned at pressure head 22 rear, described support 23 has one and accommodates chamber；Testing host 24, its
It is arranged in the receiving chamber of described support 23, and is provided with test port 25；Bridge crossing plate 26, it is arranged at the bottom of described hollow
