Brief description carries out the operation process of plug p-wire, following operations using the test fixture 100 of the present embodiment
Journey is a specific example, and the operation process that plug p-wire is carried out using the test fixture 100 of the present embodiment is not limited to down
State operation process.
Circuit board 300 can be located in positioning groove by-Fig. 6 referring to Fig.1, and be carried out further by limited post 111
Ground limits, and fixed plate 21 is mounted on sliding rail 14 by the interface 301 on the circuit board 300 towards 14 place orientation of sliding rail, and
The first sub- fixed block 221 is placed in fixed plate 21 afterwards, and makes the first magnetic absorption member on the first sub- fixed block 221 and work
The second magnetic absorption member 12 on platform 1 is opposite and attracting, so as to which the first sub- fixed block 221 is located in initial position, prevents the
One sub- fixed block 221 moves, and facilitates the connection of the follow-up first sub- fixed block 221 and fixed plate 21, the second sub- fixed block 222.
The first mounting hole on the second mounting hole and fixed plate 21 on the first sub- fixed block 221 is passed through by fastener
211, so as to which the first sub- fixed block 221 is fastened in fixed plate 21.Then USB p-wires to be plugged are positioned
In the first holding tank 2211 of the first sub- fixed block 221, the encapsulated of the connector 201 of USB p-wires is partially received in the first slot
In section 2211a and the grafting of connector 201 is partially toward outside the first holding tank 2211 of preceding stretching, and the cable part of USB p-wires holds
It is contained in the second slot section 2211b.The second sub- fixed block 222 is placed on the first sub- fixed block 221 again, is passed through by positioning pin
Then second location hole 2223 and first positioning hole 2213 pass through fastener to be pre-positioned to the second sub- fixed block 222
Across the 4th mounting hole 2222 and third mounting hole 2212 the second sub- fixed block 222 to be fixed on the first sub- fixed block 221,
Finally pushing block 23 is connected on the second sub- fixed block 222.
Pushing block 23 is pushed to drive fixation kit 2 along sliding rail 14 towards the direction (reference of the interface 301 of circuit board 300
Direction from the front to the back in Fig. 1-Fig. 4) it is mobile, until the USB that the plug division of USB p-wires is inserted on circuit board 300 is connect
In mouth 301, the grafting work of USB p-wires is completed.When needing to pull up USB p-wires, by pushing pushing block 23 to drive
Fixation kit 2 be directed away from along sliding rail 14 interface 301 of circuit board 300 direction (referring to Fig.1 in-Fig. 4 from the front to the back
Direction) it is moved to initial position, the connector 201 of USB p-wires completely disengages the USB interface 301 on circuit board 300 at this time, and
It is attracting by the first magnetic absorption member on fixed block 22 and the second magnetic absorption member 12 on workbench 1, fixation kit 2 can be located in
Initial position prevents fixation kit from moving, and this completes the plug operations of USB p-wires.
