Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram of present invention front；
Fig. 3 is partial enlargement diagram at the A of Fig. 1.
Specific embodiment
Refering to fig. 1, Fig. 2, Fig. 3, the present invention include:
One shell 1 being made of the guided way 13 of front panel 11, rear panel 12 and two sides, 1 front panel 11 of shell
Two sides are equipped with locking bar 15, and the upper side edge of front panel 11 has been equipped with and has pulled out lever 14, lower side is equipped with guide post 17, front panel 11
Several printing board slots 16 are equipped between rear panel 12, the two sides of printing board slot 16 are equipped with strip 161；
One both ends is equipped with the switching printed board 2 of Vita pin connector 21, and the two sides for printed board of transferring, which are equipped with, to be reinforced
Item 22；
One Signals Transfer Board 3 being made of radio frequency connector 31 and Vita socket connector 32；
The switching printed board 2 is successively plugged in the printing board slot 16 of shell 1, and Signals Transfer Board 3 connects through Vita socket
Connect 21 grafting of Vita pin connector of device 32 and printed board 2 of transferring.
The embodiment of the present invention:
Refering to fig. 1, Fig. 2, Fig. 3, the present invention are the digital signal test device being used cooperatively with VPX cabinet, the present invention by
Shell 1, switching printed board 2 and Signals Transfer Board 3 form；The present invention and the standard daughter board counterpart of VPX cabinet design, and have general
Interchangeability.
The connection and test of the present invention and VPX cabinet:
Refering to fig. 1, Fig. 2, Fig. 3, shell of the invention meets Vita standard according to Vita standard daughter board module design, simultaneous
Hold 0.85inch, 1.0inch cabinet, by guided way 13 be inserted into VPX cabinet slot, by locking bar 15 and rise pull out lever 14
The present invention is positioned and locked with VPX cabinet；At this point, under the guidance of the guide post 17 of 1 front end of shell, printed board 2 one of transferring
The Vita pin connector 21 at end is connect with the signal testing point of VPX case back plate modules respectively, passes through printed board of transferring
2 are drawn out to backplane signal outside VPX cabinet, turn in 21 connection signal of Vita pin connector of switching 2 other end of printed board
