One end away from the first syringe needle 112 in portion 111；The second wiring hole 123 is provided with second conductive part 21, described second connects
String holes 123 is located at one end away from the second syringe needle 122 on the second conductive part 121.First wiring hole, 113 and second wiring hole
There is screw thread, one section of conducting wire is provided with bolt, and it is detachably connected with conductive column to be connected through a screw thread mode, convenient in 123 holes
The dismounting of probe assembly is replaced with each component.Those skilled in the art can also use other connection modes, such as weld, this
The conversion of a little connection modes, belongs to the protection domain of the application.
Further, second conductive part 121 is higher relative to the height of the first conductive part 111, second wiring
Hole 123 is located at the second conductive part 121 and is higher than at the position of the first conductive part 111.Such setting can make the first wiring hole 113
Stagger with the position of the second wiring hole 123, avoid the conducting wire bolt in the first wiring hole 113 and the second wiring hole 123 to insulation
13 corresponding position of layer forms extruding, causes insulating layer 13 to damage, so as to cause 13 failure of insulation of insulating layer, influences test result
Stability and veracity.Moreover, the setting that two wire columns are one high and one low, can facilitate technical staff to understand resolution wire column
Respective effect, avoids conducting wire wrong.
First syringe needle 112 is identical with the length of the second syringe needle 122, and when ensureing to carry out test action, two syringe needles can be same
When contact tested element.There is insulating layer 13 between first syringe needle, 112 and second syringe needle 122, insulating layer 13 is at two
The needle point position of syringe needle is formed with a depressed area.Syringe needle inevitably produces abrasion, depressed area after the work of more numbers
Setting can ensure that syringe needle can work normally all the time, avoid syringe needle it is too short after insulating layer 13 to test impact.
First probe 11 is made with the second probe 12 of alloy material, and the hardness requirement of alloy material is more than 80HRA,
Can so ensure that degree of wear when the first syringe needle 112 and the second syringe needle 122 work substantially reduces, extend the first probe 11 with
In the service life of second probe 12, reduce maintenance cost.The utility model is not intended to limit the material hardness of the first probe and the second probe
Above range is had to comply with, in other embodiments, the requirement of practical application can also be adapted to, select the material of other hardness
Prepare probe.
