Background technology
IGBT module (Insulated Gate Bipolar Transistor), also known as insulated gate bipolar transistor, extensively
It is applied to practice generally.In order to judge its reliability, it is necessary to carry out parameter detecting.Existing test process generally uses test
Clip connects pin single-path testing, and its drawback is as follows: one is that test clip is compact in order to ensure that contact is the most all made,
And the pin of IGBT module is more fragile, during operation, easily injure pin；Two is that clip contact surface is less, impact test essence
Degree；Three is multichannel IGBT module when testing respectively, because pin is a lot, there is the hidden danger of polarity sniffing；Four is each list
Road is tested respectively, expends a large amount of cost of labor, and work efficiency is low.Therefore, simple in construction, easy to use, operation appearance are designed
Easily and to carry out the multichannel IGBT module test fixture of multi-channel test the most necessary simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, easy to use, processing ease and can carry out many simultaneously
The multichannel IGBT module test fixture of drive test examination.
For achieving the above object, this utility model adopts the following technical scheme that a kind of multichannel IGBT module test fixture, bag
Include platform, left location-plate, right location-plate, rear position plate, left side wall and right side wall, it is characterized in that left location-plate, right location-plate and
Rear position plate is separately positioned on the left and right of platform upper surface and rear end, and left location-plate, right location-plate can be along the upper surfaces of platform
Moving left and right, rear position plate can move forward and backward along the upper surface of platform, and left side wall and right side wall are respectively and vertically fixed at platform
Two ends, the two ends of guide rail fixed plate are connected with left side wall and right side wall respectively, and guide rail fixed plate is provided with guide rail and support,
Being provided with elevating mechanism on support, the base plate of probe base is provided with probe notch, probe notch is corresponding to IGBT module probe
Arranging, the top board of probe base is provided with guide pillar and guide rod, and guide pillar coordinates with slide, and guide rod is connected with elevating mechanism.
Further: the quantity of described probe notch is 30.
Use this utility model, tested IGBT module can be made to be accurately positioned and probe base vertical lift, thus effectively protect
The pin having demonstrate,proved probe notch and tested IGBT module patches smoothly and extracts.This utility model simple in construction, easy to use, behaviour
Make easily and multi-channel test can be carried out simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail, but this embodiment should not
It is interpreted as restriction of the present utility model.
Multichannel IGBT module test fixture shown in figure, including platform 1, left location-plate 2.1, right location-plate 2.2, determines afterwards
Position plate 2.3, left side wall 3.1 and right side wall 3.2, left location-plate 2.1, right location-plate 2.2 and rear position plate 2.3 are separately positioned on flat
Left and right and the rear end of platform 1 upper surface, left location-plate 2.1, right location-plate 2.2 can move left and right along the upper surface of platform 1, after
Location-plate 2.3 can move forward and backward along the upper surface of platform 1, and left side wall 3.1 and right side wall 3.2 are respectively and vertically fixed at platform 1
Two ends, the two ends of guide rail fixed plate 4 are connected with left side wall 3.1 and right side wall 3.2 respectively, guide rail fixed plate 4 is provided with and leads
Rail 5 and support 6, support 6 is provided with elevating mechanism 7, and the base plate of probe base 8 is provided with probe notch 9, probe notch 9 with
IGBT module probe is arranged accordingly, and the top board of probe base 8 is provided with guide pillar 10 and guide rod 11, and guide pillar 10 slides with guide rail 5 and joins
Closing, guide rod 11 is connected with elevating mechanism 7.
