Description

Communication power amplifier module test fixture

Technical field

The utility model relates to the test fixture of the power amplifier module in the communication equipment, particularly relate to the fixing and test fixture of guide-localization accurately of a kind of whole cable, it is applicable to the test of the power model in the communication equipment.

Background technology

Adopt the power amplifier module test macro in the current communication system, directly use transit cable and switching PCBA as the switching frock, in operation, because transit cable and switching PCBA's is unfixing, the moving influence of Chang Yinwei cable or PCBA test in the test, the efficient and the accuracy of influence test significantly, and transit cable frangibility, loss is bigger, and the joint on the PCBA is because of there not being accurate in locating, and is fragile especially in test.Therefore, in producing the power amplifier module process in batches, traditional test fixture can not be satisfied the demand.

The utility model content

The utility model provides a people just can operate at above-mentioned situation, accurate positioning, and simple to operate, cable and radio frequency plug damage less test fixture.

In order to achieve the above object, the utility model adopts following technical scheme: the test fixture of the power amplifier module in a kind of Wireless Telecom Equipment, the upper end of bracing frame is equipped with by the adjustment piece and moves up and down device, the lower end that moves up and down device is connected with the switching cavity, the switching cavity bottom is respectively arranged with switching PCBA, alignment pin, lead, the switching cable at switching PCBA and bracing frame rear portion is connected, and lead stretches in the guiding linear bearing on the platform of bracing frame lower end connection.

The described device that moves up and down is made of clamp, handle, intercell connector, joint pin, wherein the upper end of joint pin is hinged with intercell connector, the other end of intercell connector is hinged on the handle, handle is hinged on the clamp upper end, the through hole that the clamp lower end is passed in the lower end of joint pin is connected with the switching cavity, and clamp is connected to be adjusted on the piece.

Described platform bottom is provided with radiator, and the side of described platform is provided with location-plate.

The utility model cooperates to provide and moves up and down by lead and guiding linear bearing, the taper location of conical dowel pin, thus make accurate positioning, simple to operate, a people just can operate, and cable and radio frequency plug damage are less.Avoid the shake of radio frequency plug and cable in the power amplifier module test to bring the error of test index fully by the variation of structure, improved the operating efficiency and the quality of this test station to a great extent.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

The test fixture of the power amplifier module in a kind of Wireless Telecom Equipment of the utility model is seen Fig. 1, Fig. 2, shown in Figure 3, the upper end of bracing frame 1 is equipped with by adjustment piece 2 and moves up and down device, the lower end that moves up and down device is connected with switching cavity 4, switching cavity 4 bottoms are respectively arranged with switching PCBA6, alignment pin 9, lead 7, the switching cable 5 at switching PCBA6 and bracing frame 1 rear portion is connected, and lead 7 stretches in the guiding linear bearing 8 on the platform 12 of bracing frame 1 lower end connection.The described device that moves up and down is made of clamp 3, handle 13, intercell connector 14, joint pin 15, wherein the upper end of joint pin 15 is hinged with intercell connector 14, the other end of intercell connector 14 is hinged on the handle 13, handle 13 is hinged on clamp 3 upper ends, the through hole that clamp 3 lower ends are passed in the lower end of joint pin 15 is connected with switching cavity 4, and clamp 3 is connected to be adjusted on the piece 2.Described platform 12 bottoms are provided with radiator 11, and the side of described platform 12 is provided with location-plate 10.

As accompanying drawing 1, module is placed on the radiator, swing active grab 3 makes the frock stroke downward, cooperating of linear bearing 8 provide rectilinear motion accurately by lead 7 with guiding, alignment pin 9 moves downward near module, utilizes alignment pin taper and module location hole to make module Xiao Xu move to radio frequency plug positions aligning with transit cable 5, depresses active grab then, module connector and transit cable 5 radio frequency plugs contact fully with connector above the PCBA, begin test then.Test is finished and is lifted active grab, when alignment pin breaks away from the module location hole, can take off module and finish whole process.Whole process is simple to operate, quick to frock, and provides accurately and be located by connecting, and improves the accuracy and the efficient of system testing.
