As shown in fig. 1 to 6, according to an embodiment of the present invention, a test fixture 100 for a display 510 of an electronic device 500, the test fixture 100 includes: a base 10, a motherboard 20, a control circuit (not shown), and a control switch 30.
Specifically, as shown in fig. 1 and 3, the base 10 is provided with a housing 121, and the display 510 is adapted to be placed in the housing 121. Thus, by providing the receiving portion 121, the display screen 510 can be fixed to the receiving portion 121 so as to perform a performance test on the display screen 510.
The main board 20 is disposed on the base 10, one end of the control circuit is connected to the main board 20, and the other end of the control circuit is adapted to be connected to the display 510. Thus, the connection between the main board 20 and the display screen 510 may be implemented by a control circuit to perform a performance test on the display screen 510.
The control switch 30 is positioned at the accommodating part 121, and the control switch 30 controls the on-off of the control circuit, wherein when the display screen 510 is placed at the accommodating part 121, the display screen 510 triggers the control switch 30 to be opened, and the control circuit is conducted; when the display 510 is separated from the accommodating portion 121, the control switch 30 is turned off, and the control circuit is turned off.
When performance testing of the display screen 510 is required, the display screen 510 may be connected to a control circuit, and the display screen 510 may be fixed in the accommodating portion 121. When the display screen 510 is placed in the accommodating portion 121, the display screen 510 triggers the control switch 30 to be turned on, and the control circuit is turned on, so that the main board 20 is connected with the display screen 510 to perform performance test on the display screen 510.
When the display screen 510 to be tested needs to be replaced, the display screen 510, which was previously tested, is taken out from the housing part 121, and at this time, the control switch 30 is turned off, thereby disconnecting the electrical connection between the main board 20 and the display screen 510, and then the test flat cable of the display screen 510 can be pulled out. The above steps are repeated to perform performance testing on the display 510 to be tested. Therefore, when the performance test is performed on the batch display screen 510, the main board 20 does not need to be turned off, and the test efficiency is improved. Moreover, when the display screen 510 is separated from the accommodating part 121, the control switch 30 controls the disconnection control circuit to disconnect the main board 20 from the display screen 510, so that no current passes through the display screen 510 during the plugging process of the display screen 510, and the defect that the display screen 510 is damaged by the generated electric surge when the display screen 510 is plugged with a power board is avoided. Moreover, the on/off of the control switch 30 is controlled by the state of the display screen 510 on the accommodating portion 121, so that the test fixture 100 has a good fool-proof effect.
According to the test fixture 100 for the display screen 510 of the electronic device 500 in the embodiment of the invention, by arranging the control switch 30 in the accommodating portion 121, whether the display screen 510 is placed in the accommodating portion 121 can control the on or off of the control circuit, so that the display screen 510 is in a power-off state in the plugging process, and the defect that the display screen 510 is damaged by electric surge generated by hot plugging of the display screen 510 is prevented. In addition, whether the display screen 510 is placed in the accommodating portion 121 to control the on/off of the control circuit is adopted, so that the test fixture 100 has a good fool-proof effect.

One end of the fulcrum portion 320 is fixed to the base 10, the link lever 310 is pivotably connected to the fulcrum portion 320, and the fulcrum portion 320 and the link lever 310 are configured as a lever mechanism.
It will be appreciated that display screen 510 is itself lightweight and that display screen 510 cannot withstand significant stresses so as not to cause damage to display screen 510. By setting the control switch 30 as a lever mechanism, when the display screen 510 is placed in the accommodating portion 121, the display screen 510 presses the first end 311, and under the action of the lever mechanism, the smaller pressure of the display screen 510 is amplified, so that the second end 312 touches the control circuit, the control circuit is conducted, and the electrical connection between the main board 20 and the display screen 510 is realized, so that the performance test is performed on the display screen 510.

That is, the fulcrum portion 320 may be disposed proximate the second end 312. According to the lever principle, the second end 312 of the connecting rod 310 can be tilted by the display screen 510 which is lighter at the first end 311, so that the second end 312 contacts with the control circuit to communicate with the control circuit. Moreover, the display screen 510 can be prevented from being damaged due to the fact that the first end 311 generates larger pressure on the display screen 510, and the stability and reliability of operation of the test fixture 100 are improved.
According to some embodiments of the present invention, the fulcrum portion 320 may be a bearing, with which the connecting rod 310 is pivotally connected. Thus, by providing the fulcrum 320 as a bearing, the frictional force generated when the connecting rod 310 and the fulcrum 320 are rotated relative to each other can be reduced, and the display screen 510 can be made more sensitive to trigger the control switch 30.
In some embodiments of the present invention, as shown in fig. 1-3, a base station 10 may include: the two support plates 110 and the bearing plate 120, the two support plates 110 are arranged at intervals, two ends of the bearing plate 120 are fixedly connected with the two support plates 110 respectively, the accommodating part 121 is located on the upper surface of the bearing plate 120, and the connecting rod 310 and the fulcrum part 320 are located on the lower surface of the bearing plate 120. By disposing the accommodating portion 121 on the upper surface of the carrier plate 120, the display screen 510 is conveniently placed and fixed.

That is, the on time of the first circuit is longer than that of the second circuit, and it should be noted that the first circuit may be a circuit for controlling the display screen 510 to be on or off, and the second circuit may be a thermal plug-in protection circuit. The hot plug prevention described herein is understood to prevent damage to the display screen 510 caused by a plug operation of the display screen 510 in an energized state. The voltage of the first circuit is greater than the voltage of the second circuit. Therefore, the control module controls the second circuit with small voltage to be firstly connected and then the first circuit with large voltage to be connected, so that the display screen 510 can be effectively protected.
When the control switch 30 is turned off, the control module controls the time of the first circuit to be turned off to be t3, and the control module controls the time of the second circuit to be turned off to be t4, so that the following conditions are satisfied: t3 > t4.
