Embodiment

See also shown in Figure 2, the utility model includes test board group 1, pass through the probe unit 2 that is fixedly arranged between the test board group 1, be positioned at the web joint 8 and the winding displacement 4 of test board group 1 below, wherein, test board group 1 forms for a plurality of test boards 10 folded groups, above have on several layers of test plate body and arrange orderly most holes 11, test board hole 11 can ccontaining probe unit 2;

See also Fig. 8, Fig. 4, Fig. 5, shown in Figure 6, probe unit 2 includes a probe bodies 20 and an extension closes plane body 21, probe bodies 20 tools one probe 200 wherein, probe 200 lower ends can be free to slide stretches in the probe body 201 of below, probe body 201 is a hollow tube, can insert probe 200 lower ends and a body 202 in the probe body 201 in the below of probe 200 lower ends, 201 collocation of probe body are hung and are closed hole 210 diameters of being opened on the plane body 21, tool is equipped with a scrobicular ring 208 and probe bodies 20 is snapped in hang and close in the plane body 21, and the probe body is connected to a connection line 22 for 201 times, with the usefulness as transmission test message;

It is the plane plate made of the flexible material of tool such as colloid slightly that extension closes plane body 21, extension closes number and the arrangement position that has most holes 11 of arranging whole preface on the plane body 21 according to test board group 1, also have simultaneously most holes 210, extension closes that plane body hole 210 diameters are slightly larger than scrobicular ring 208 diameters approximately and less than the diameter in probe body 201 cross sections, when probe bodies 20 and extension close plane body 21 and combine, only probe bodies 20 need be taken advantage of a situation to insert to hang and close plane body hole 210, because hanging and closing plane body 21 is so that flexible material of tool such as colloid are made slightly, therefore the probe bodies of inserting 20 of can being taken advantage of a situation is slightly compeled out, restore to the original state when the material of closing plane body hole 210 peripheries snaps in scrobicular ring 208 to hanging, with function as the supporting probe body;

The message that the connection line 22 that probe bodies connects for 20 times can receive probe 200 is imported the web joint 8 and winding displacement 4 that is positioned at test board group 1 below into through connection line 22, by screen (networking) the maintenance software of winding displacement 4 and an external special tester and the use of collocation special designs thereof, use the running of carrying out measuring ability.

Please cooperate Fig. 7, shown in Figure 8, when the utility model uses, circuit under test plate body 5 need only be placed on the test board group 1, by the probe 200 thoughts and feelings messages that are placed in the most holes 11 of test board group, the connection line 22 that connects for 20 times through probe bodies imports the web joint 8 and winding displacement 4 that is positioned at test board group 1 below into, by screen (networking) the maintenance software of winding displacement 4 and an external special tester and the use of collocation special designs thereof, use to carry out and detect circuit under test plate body 5;

And probe unit 2 not known in the past for another example probe 20 ' (as shown in Figure 1) rely on the protruding wall 22 ' of protuberance to support to support as button, probe bodies 20 of the present utility model is with probe 200, probe body 201 is one-body molded with body 202, must not wait the action that repeats with body 21 ' by otherwise combined probe 20 ' during assembling, only probe bodies 20 need be taken advantage of a situation to insert to hang and close plane body hole 210, because hanging and closing plane body 21 is so that flexible material of tool such as colloid are made slightly, therefore, the probe bodies of inserting 20 of can being taken advantage of a situation is slightly compeled out, and restores to the original state when the material of closing plane body hole 210 peripheries snaps in scrobicular ring 203 to hanging.

The utlity model has following advantage:

One, assembling is simplified, when most probe units that are shaped 2 and 11 assembling of test board group hole, Because the numbers of poles of test board group hole 11 is many, therefore with the process simplification of assembling, can really reduce The processing fraction defective.

Two, engaging ability is good, and the extension of making by the slightly flexible material of tool such as colloid closes plane body 21, Can really engage probe bodies 20.

Three, can control the quantity of test board group 1 in good time, and must not utilize the support of test board group 1, strengthen the dirigibility of test board group 1 as known probe 20 '.
