[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 , Figure 2 and Figure 3 As shown, a mobile phone chip testing device includes a housing 10, a display screen 100 and a voltmeter / ammeter 200 mounted on the top of the housing 10, a testing component 20 disposed on one side of the display screen 100, the testing component 20 being electrically connected to the display screen 100 and the voltmeter / ammeter 200 respectively, the testing component 20 including a base 300, a receiving groove 310 disposed on the top of the base 300 for placing a mobile phone chip, and a pressing component 400 disposed above the base 300 for pressing the mobile phone chip tightly within the receiving groove 310.

[0022] In the working state of this embodiment, the mobile phone chip to be tested is first placed in the receiving slot 310, and then pressed by the pressing component 400. Then, the power is turned on, and a predetermined signal is injected into the pin of the chip under test. Then, the response generated by the chip output port is carefully detected by the display screen 100 and the voltage and current meter 200, so as to accurately determine whether the chip can work normally and whether it achieves the expected effect.

[0023] Compared with the prior art, this application integrates a display screen 100, a voltage and current meter 200, and a test component 20 into a housing 10. By injecting a predetermined signal into the pins of the chip under test, the response generated by the chip's output port is detected, so as to perform comprehensive testing of the chip's function, performance, and reliability, ensuring that the chip can work normally in various usage environments, thereby achieving the expected effect.

[0024] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 2 As shown, a support 11 is provided inside the housing 10. The support 11 is fixed to the inner side of the top surface of the housing 10. The base 300 is installed on the support 11, so that the entire test assembly 20 can be fixed to the top of the housing 10.

[0025] Furthermore, based on the above embodiments, such as Figure 3 As shown, the base 300 includes an upper clamping plate 320 and a lower clamping plate 330. The receiving groove 310 is installed on the top of the upper clamping plate 320. A circuit board 340 is disposed between the upper clamping plate 320 and the lower clamping plate 330. The circuit board 340 is clamped and fixed by the upper clamping plate 320 and the lower clamping plate 330. The circuit board 340 is electrically connected to the display screen 100 and the voltmeter and ammeter 200. Since the base 300 is suspended on the top surface of the receiving box 10, the circuit board 340 can be clamped and fixed by the upper clamping plate 320 and the lower clamping plate 330 first, thereby preventing the circuit board 340 from shaking when the base 300 is installed on the support 11.

[0026] Furthermore, based on the above embodiments, such as Figure 3 As shown, a first through hole 311 is provided at the bottom of the receiving groove 310. A pin plate 350 is provided between the upper clamping plate 320 and the circuit board 340. Several test probes 351 are installed on the top of the pin plate 350. The test probes 351 are electrically connected to the circuit board 340. The test probes 351 are located directly below the first through hole 311. A spring 360 is provided between the pin plate 350 and the receiving groove 310. When the mobile phone chip is placed in the receiving groove 310 and pressed by the pressing assembly 400, the receiving groove 310 moves downward as a whole under the support of the spring 360. The test probes 351 pass through the first through hole 311 and contact the pins at the bottom of the mobile phone chip, so that a predetermined signal can be injected into the pins of the chip under test. Then, the response generated by the chip output port can be carefully detected by the display screen 100 and the voltage and current meter 200.

[0027] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5 As shown, the pressing assembly 400 includes a surrounding plate 410 and a cover 420. The surrounding plate 410 and the cover 420 are connected by a pivot 430. The surrounding plate 410 is disposed on the top of the receiving groove 310 and surrounds the receiving groove 310. A pressing block 421 is provided on the cover 420. When the cover 420 and the surrounding plate 410 are closed with the pivot 430 as the axis, the surrounding plate 410 can ensure that the pressing block 421 can extend into the receiving groove 310 to press the mobile phone chip.

[0028] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5As shown, a knob 422 is provided on the top of the cover 420. The pressure block 421 passes through the cover 420 and is connected to the knob 422. A stud 423 is connected between the knob 422 and the pressure block 421. The stud 423 is disposed inside the cover 420 and is rotatably connected to the cover 420 by a thread. That is, the stud 423 can be rotated inside the cover 420, so that the stud 423 can move up and down inside the cover 420. When the cover 420 and the surrounding plate 410 are closed, the knob 422 can be operated to rotate the stud 423, so that the pressure block 421 can gradually press the mobile phone chip, thereby avoiding damage to the mobile phone chip caused by sudden pressing.

[0029] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5 As shown, a latch 424 is provided on the side wall of the cover 420, and a limiting groove 411 is provided on the surrounding plate 410 to cooperate with the latch 424. When the cover 420 and the surrounding plate 410 are closed, the latch 424 can be fastened in the limiting groove 411, thereby preventing the cover 420 and the surrounding plate 410 from disengaging from the closed state.

[0030] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5 As shown, two operating levers 425 protrude outward on one side of the knob 422. The operating levers 425 are arranged opposite each other, so that the operator can rotate the knob 422 more conveniently by moving the operating levers 425.

[0031] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
