Preferably, described hold-down mechanism also comprises guide plate and two guide poles vertically arranged, and described guide plate is fixed on described pressure bar lower end, and described briquetting is arranged on described guide plate; Described two guide poles slide through described orienting lug.
Preferably, two described spring needles contact with a pin of tested power module.
Preferably, the material of described briquetting is phenoplast.
As can be seen from above, the power module test fixture that the utility model provides, overcome the deficiency that mode that special package power module directly cannot be connected by socket or connecting line realizes testing, hold-down mechanism is adopted to make tested power module holddown spring pin, and be connected with test macro by connector, namely ensure that measuring accuracy, in turn ensure that stability and the reliability of measurement.
Accompanying drawing explanation
Fig. 1 is the power module test fixture structural representation of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
A kind of power module test fixture that the utility model embodiment provides, comprise operator's console, connector and hold-down mechanism, described operator's console upper surface is provided with the groove for placing tested power module, described bottom portion of groove is provided with several spring needles for contacting with the pin of power module, described spring needle is connected to described connector by wire, and described connector is used for being connected with power module test macro; Described hold-down mechanism is arranged on described operator's console upper surface, comprises handle, first connecting rod, second connecting rod, pressure bar, briquetting, guide cylinder; Described guide cylinder extends upward a stiff end; Described first connecting rod one end is hinged to described stiff end, the other end is hinged to described pressure bar one end by described second connecting rod, the described pressure bar other end connects described briquetting, and described pressure bar is placed in described guide cylinder, and described handle is hinged to the pin joint of described first connecting rod and second connecting rod; Pull described handle, and by the transmission of described first connecting rod and second connecting rod, described pressure bar is moved down in described guide cylinder and makes described briquetting compress described spring needle.
Be placed on by the tested power module of surface mount packages in the groove of power module test fixture operator's console upper surface of the present embodiment, groove size is roughly the same with the outside dimension of tested power module, plays preliminary fixing measured device effect.The Surface Mount pin direction of tested power module down, contact with the spring needle that groove floor is stretched out, tested power module and spring needle are compressed by compressing structure, make pin and the spring needle good contact of tested power module, spring needle is connected with connector by wire; Compact in order to integral clamp, connector is preferably arranged on the sidewall of operator's console.Connector is connected with power module test macro, and the hardware resource of test macro is forwarded on spring needle by above-mentioned connection, again by the tight good contact of spring needle and tested power module, the hardware resource of test macro is acted on tested power module, completes test process.
With reference to figure 1, it is the power module test fixture structural representation of the utility model embodiment.
As an embodiment, hold-down mechanism also comprises guide plate 13 and two guide poles 14 vertically arranged.Guide plate 13 is fixed on pressure bar 9 lower end, and briquetting 10 is fixed on guide plate 13.What two guide poles 14 were vertical is fixed on operator's console 1 upper surface, and slides through orienting lug 14.
In the present embodiment, hold-down mechanism makes briquetting 10 holddown spring pin 5, to ensure measuring accuracy, its specific works process is: during initial position, handle 6 is in upwards lifting status, first connecting rod 7 and second connecting rod 8 are with the pin joint both it for summit angle in an acute angle, and briquetting 10 is in the position away from groove 4.Be placed in by tested power module 3 after in groove 4, its pin contacts with the spring needle 5 in groove 4.Pull handle 6 downwards, under the drive of handle 6 first connecting rod 7 with stiff end 12 for axle rotates, and pass through the transmission of second connecting rod 8, pressure bar 9 is moved downward along guide cylinder 11, guide plate 13 also moves downward along two guide poles 14 with pressure bar 9, and then briquetting 10 is moved down contact with tested power module 3, and applies a downward pressure to it, make pin and the spring needle 5 closely good contact of tested power module 3, complete the fixing of tested power module 3.After completing test, upwards pull handle 6, above-mentioned transmission process is reversed, and pressure bar 9 moves upward, and returns initial position, and it, away from tested power module 3, can take out by briquetting 10 easily.
In said process, pressure bar 9, when moving up and down, is subject to the restriction of guide cylinder 11, and the auxiliary guiding that guide plate 13 moves along two guide poles 14, makes its motion process more steady, is convenient to manipulation.
As preferably, all corresponding two spring needles 5 of each pin of tested power module, namely in groove 4, two spring needles 5 contact with a pin of tested power module, can avoid the inaccurate problem of measurement caused during high-current test like this.
In the present embodiment, the material of briquetting 10 is phenoplast.Briquetting 10 hardness of phenoplast material is moderate, can not damage device, have in addition do not absorb water, non-conductive, resistant to elevated temperatures character, there is preferably serviceable life.
