A kind of adapter that is used for mobile phone test
Technical field
The utility model relates to a kind of adapter that is used for mobile phone test.
Background technology
The cell-phone function test is widely used in mobile phone assembling field tests.In the test practical operation, the switching of connector is one of necessary link in the test process, and its operability and precision will directly have influence on test speed and precision.
As Fig. 1; shown in 2; prior art is used for the adapter of mobile phone test; comprise pedestal 6 '; driver-extractor 1 ' and protection seat 7 '; probe upwards runs through pedestal 6 '; pedestal 6 ' upper surface is provided with reference column; pcb board 4 ' is placed on the reference column; the pad face of pcb board 4 ' lower end contacts with the upper end of probe 5 '; pcb board over cap 2 ' covers on pcb board 4 '; pcb board over cap 2 ' upper end is provided with the perforate that the connector 3 ' with pcb board 4 ' upper surface is complementary; pcb board over cap 2 ' plays a part spacing to pcb board 4 ' and protection; driver-extractor 1 ' one end flexibly connects by a side of alignment pin 8 ' and spring 10 ' and pedestal 6 '; the upper end of pcb board over cap 2 ' embeds the other end of driver-extractor 1 '; the lower end of probe 5 ' is connected with lead; protection seat 7 ' is fixedlyed connected with the lower surface of pedestal 6 '; protection seat 7 ' comprises the probe protection part on top and the lead stop portion of bottom; its probe protection partly has through hole; the part that probe 5 ' lower end exceeds pedestal 6 ' places in this through hole; make outside probe 5 ' avoids being exposed to; cause the unnecessary signal shorts and the breaking-up of probe; the lead stop portion is the clamp 9 ' that is provided with two flutings; after the lead that probe 5 ' lower end connects passes fluting; clamp 9 ' closes fixing, guarantees that lead is from desirable position cabling.
During test, the connector on the workpiece is contacted applying with the connector 3 ' of pcb board 4 ' upper surface, the instrument that is connected with lead to workpiece send pumping signal or from the workpiece acquired signal, reach the purpose that cooperates test.After test finishes, pull an end of driver-extractor 1 ' downwards, under the effect of lever principle, the other end of driver-extractor 1 ' is upwards extracted the connector on the workpiece, and driver-extractor 1 ' is returned to initial position under the effect of spring then.
Adopt above-mentioned adapter, have following problem: 1, driver-extractor is the material of all steel, its rough surface, quality is hard, and rise when pulling out, the connector both sides on the workpiece are stressed because driver-extractor is too hard and workpiece on the connector local pressure, in getting the process of pulling out, be easy to the connector on the workpiece is caused damage or shortens its useful life, thereby reduce the qualification rate of product; 2,,, when pcb board being positioned, be difficult to guarantee that pcb board fully contacts with probe by the pcb board over cap if manufacturing tolerance is big because the pcb board over cap is an opaque material; 3, when changing pcb board, need take off driver-extractor earlier, unload PCB location lid again, change pcb board again, this often needs to expend considerable time, thereby influences Production Line speed.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, and a kind of adapter that is used for mobile phone test is provided.
The utility model realizes that the above-mentioned purpose scheme is: a kind of adapter that is used for mobile phone test, comprise pedestal, driver-extractor, protection seat, probe and pcb board, and wherein, described probe upwards runs through pedestal; The protection seat is fixed on the lower surface of pedestal, and the part that the probe lower end exceeds pedestal places in the protection seat, and the lead that the probe lower end connects passes the protection seat; Described pcb board is fixed on the pedestal upper surface, and the pad face of its lower end contacts with the upper end of probe; Described driver-extractor is an elastic component, and the one end is fixedly mounted on the upper surface of pedestal, and the connector of pcb board upper surface runs through driver-extractor.
Described driver-extractor is provided with the through hole that the connector with the pcb board upper surface is complementary, and the connector of pcb board upper surface embeds in this through hole.
The contact-making surface of described probe and pcb board is circular.
Also comprise pad, be installed in the pedestal upper surface, described pad supports the stiff end of driver-extractor.
Described pad is an elastic component.
Described pcb board by screw in the pedestal upper surface.
Described driver-extractor have with pcb board on position, the corresponding hole of screw.
Adopt the beneficial effect of above scheme:
Adopt flexible driver-extractor, when getting the connector that pulls out on the workpiece, only need stir an end of driver-extractor, connector on the workpiece can be ejected, make and reduce damage by force balance around the connector on the workpiece, especially in mobile phone test, reduce damage, thereby increase the life-span of connector, improve the qualification rate of product the mobile phone micro connector.
When change takes place the project of mobile phone products type or required test, only need to change pcb board, change pcb board in the prior art, to pull up driver-extractor with the instrument of thimble one class earlier, take off spring, back out the hold-down screw of pcb board over cap then, from the pcb board over cap, pour out pcb board again; And adopt structure of the present utility model, and only need unload the hold-down screw of driver-extractor, take off pcb board to get final product, simple and quick, easy to maintenance, greatly improved Production Line speed.
When getting the connector that pulls out on the workpiece, press the other end of driver-extractor, the through hole projection on the driver-extractor, the connector that drives on the workpiece is extracted, thus ejection under the evenly stressed situation of the connector on the workpiece fast and safely.
The contact-making surface of probe and pcb board is circular, probe is fully contacted with the pad face of pcb board, thereby probe can fully pass through the pcb board acquired signal.
The stiff end that pad supports driver-extractor is set, makes driver-extractor entirely to be installed on the pedestal 6.
Have on the driver-extractor with pcb board on position, the corresponding hole of screw, when screw did not embed pcb board fully, the top of screw was as in the position, hole, kept smooth being placed on the pcb board of driver-extractor.
