In the utility model, it is equipped with guide rod between top plate and bottom plate, the connection that can be slided on guide rod is socketed on guide rod
Plate, it is corresponding so that the position change of probe is tested, for the different transformation of pin length when connecting plate slides on guide rod
Device, the height by adjusting connecting plate can be such that test probe is contacted with pin, so as to the different change of test pin length
Depressor.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the measurement jig of the high frequency transformer of embodiment of the utility model.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode combination attached drawing.
The utility model embodiment provides a kind of measurement jig of high frequency transformer, as shown in Figure 1, high frequency transformer 100
It is encapsulated in a box body, multiple pins 101 is exposed on box body, the quantity of usual pin 101 is even numbers, is arranged in two rows.This
The measurement jig of embodiment needs fixed high frequency transformer 100, and the pin 101 of relevant test equipment and transformer is made to be electrically connected
It connects, to test the relevant parameter of high frequency transformer 100.
The measurement jig includes top plate 1 and bottom plate 2 disposed in parallel, can connect between top plate 1 and bottom plate 2 and connect accordingly
Extension bar or connecting plate, so that top plate 1 and bottom plate 2 are firmly fixed together.It is equipped between the top plate 1 and bottom plate 2 and vertically prolongs
Several guide rods 3 stretched, guide rod 3 forms guide rail, the connecting plate 4 that can be slided on guide rod 3 is socketed on the guide rod 3, described
It is additionally provided on guide rod 3 for 4 clamping fixed of connecting plate on guide rod 3 or to be loosened take-up 31 to 4 clamping of connecting plate.
Specifically, the take-up can be by 4 clamping fixed of connecting plate, making can not be free to slide on its reconducting lever 3, it is also possible to
Loosen the clamping to connecting plate 4 so that it can free to slide.It is offered on the top plate 1 multiple slotting for transformer lead pin 101
The jack 10 entered, the position of jack 10 and quantity need naturally and the pin of high frequency transformer 100 101 matches.The connection
Plate 4 is equipped with multiple test probes 41 corresponding with the jack 10, the position of test probe 41 position and quantity and jack 10
It sets and matches with quantity.Meanwhile the test probe 41 can also pass through conducting wire 42 and connect external test facility.
When in use, high frequency transformer 100 is fixed on jack 10, adjusting elasticity device 31, sliding connection plate 41 makes
Test probe 41 is contacted with pin 101, then fixed take-up 31.It can be tested.The position height for testing probe 41 can
To change, so as to the different transformer of test pin length.
In one embodiment, the guide rod 3 is equipped with screw thread, and the take-up 31 matches with the screw thread
Adjusting nut can directly make connecting plate 4 correspond to sliding by rotating adjusting nut.Further, the adjusting on same guide rod 3
There are two nut is set, two adjust screw thread and are separately positioned on above and below connecting plate 4, to grip connecting plate 4, enhancing pair
