Utility model content
The utility model, in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, practicalProperty strong amplifier test fixture, to ensure that amplifier module is quick, convenient, effectively debugging.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of amplifier test fixture, comprises the left testboard, middle testboard, the right testboard that connect successively,On described left testboard, right testboard, use respectively pan head screw will input micro-band plate, export micro-band plate admittedlyFix on left base station, right base station, and install respectively as survey the side of described left testboard, right testboardThe N Connector of trial signal input port, output port; On described middle testboard, use pan head screw to incite somebody to actionAmplifier module to be tested is fixed on testboard; Described left testboard, right testboard and middle testboardBetween be rotatably connected.
Preferably, between described left testboard, right testboard and middle testboard, all adopt elasticity gemel connection.
Further, in the time that elasticity hinge is in nonrotating state, the pad of the micro-band plate of described input, putThe pad of large device module, the pad of exporting micro-band plate are close to successively; And fix adjacent pad by soldering.
Further, after amplifier module has been tested, when the tin solder of softening left side, rotation is leftTestboard, when the scolder of softening right side, rotates right testboard, separates adjacent testboard.
Preferably, be evenly arranged radiation tooth at described middle testboard downside.
The beneficial effects of the utility model are:
1), testboard profile of the present invention can be designed to 150mm × 40mm × 30mm, weight is 2kg, knotStructure profile is little, lightweight, and not modulated examination constraint based on sites can be in the debugging of having gone out to drill of common debugging table,And the carrying of debugging part is light.
2), this test fixture can produce once, use for a long time, and can be in the assembling of emitting module entiretyFront debugging, has accelerated development of projects.
3), use elasticity gemel connection between adjacent testboard, after softening scolder along the freedom of elasticity hingeJust can separate adjacent block to the left testboard of rotation, right testboard, and this rotary structure also justIn taking out amplifier module, can not be stuck in mounting groove.
4), to sum up, the utility model is by the adjacent testboard of elasticity gemel connection, and overall weight is light, bodyLong-pending little, simple in structure, be convenient to debugging operations; Rotary structure is conducive to change high power amplifier, tears openDress maintenance efficiency is high, and reliable operation and stablize, can effectively reduce commissioning staff's assembling and bear, marketHave a extensive future.
