Formula arrangement is drawn, and is facilitated multimeter or CRO coupling to contact conducting and is tested, and is labelled with test matrix on pad
Line number and row number, the identification of contact when the later period being facilitated to test；
Pad 6 is inserted into case back plate by the plug and realizes electric connection for the device plug that is of coupled connections；
Screw by via hole 1-1 that size is 5.1mm it is fixed with the first socket pad (2), the second socket pad (3) and the
The connector body of three socket pads (4) coupling, by the fixed shell of via hole 1-2 that size is 2.7mm, screw passes through big screw
The connector plug of the fixed insertion case back plate of the via hole 1-4 that the small via hole 1-3 for being 3mm, size are 4.65mm.
First socket pad 2, the second socket pad 3, third socket pad 4 are used to the connection that coupling meets VPX standard
Device socket, each VPX standard connector socket are made of tri- connector bodies of P0, P1, P2, and P0 is the square of 9 rows 8 column
Battle array, P1, P2 are the matrix of 9 rows 16 column.The P0 connection of first socket pad 2, the second socket pad 3 and third socket pad 4
Device is meet VPX standard same, and the difference of these three pads is mainly: P1, P2 of the first socket pad 2 are difference letter
Number, it is respectively used to coupling P1 differential connector and P2 differential connector；The P1 of second socket pad 3 is single-ended signal, P2 is poor
Sub-signal is respectively used to coupling P1 single-ended connector and P2 differential connector；P1, P2 connector of third socket pad 4 is
Single-ended signal is respectively used to coupling P1 single-ended connector and P2 single-ended connector.
First socket pad 2, the second socket pad 3, third socket pad 4 pass through cabling design and testing weld pad 5, VPX
Plug pad 6, which is realized, to be electrically connected, the connection coupled with the first socket pad 2, the second socket pad 3 and third socket pad 4
Device socket plugs 3U board to be tested, the pin on 3U board by the pin on the track and deck on pinboard one by one
Correspondence is electrically connected, and is realized complete signal transmitting, is finally inserted into the connector plug coupled with VPX plug pad 6
Case back plate, the on-line debugging of 3U board to be tested in the standard PC case to realize 3U VPX framework.
Patent advantage:
(1) it solves the problems, such as that VPX cabinet hardware on-line debugging is difficult, by the way that VPX daughter board is drawn cabinet, realizes VPX
Daughter board connector can measure online.
(2) sequencing plate lays the socket of three types, meets Double deference, double single-ended, single-ended+difference three types
The testing requirement of 3UVPX board, universal test plate reduce development cost.
(3) test board carries drawing-aid device, can facilitate insertion VPX cabinet, favorably quickly test on site.
(4) the testing weld pad mark on test board is clear, searches test point when facilitating on-line debugging, improves work effect
Rate.
