Description

Technical Field

[0001] This utility model relates to the field of optical communication testing technology, and in particular to a power-on testing device for circuit boards. Background Technology

[0002] Optical modules are one of the most important components in modern communications. Their main function is photoelectric conversion. The transmitting end converts electrical signals into optical signals, which are then transmitted through optical fibers. The receiving end then converts the optical signals back into electrical signals.

[0003] To ensure the power supply and safety performance of the circuitry in the optical module during normal operation, performance testing of the internal PCB is required during the production process. Traditional open-circuit voltage testing of optical modules requires manual measurement of the voltage to ground point by point using a multimeter. The internal circuitry of the optical module involves multiple power supply functions (such as soft-start power supply voltage, EML bias voltage, drive voltage, etc.), and multiple test points are time-consuming.

[0004] Furthermore, the PCB test points inside the optical module are densely packed (such as 0.5mm pitch pads), and manual probes are prone to short-circuiting adjacent points; in addition, the testing efficiency is low, and the testing time for a single module is ≥3 minutes; at the same time, manual inspection is prone to problems such as missed tests, insufficient tests, and accidental contact. Therefore, a power-on testing device for circuit boards is provided. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a circuit board power-on testing device that eliminates the need for manual point-by-point measurements with a multimeter. By simultaneously contacting multiple test points with probes, it solves the problem of short-circuiting adjacent points during manual testing, shortens the testing time for a single module, and avoids missed tests, insufficient tests, and accidental contact. At the same time, the host computer can automatically generate a fixed-format data table, which facilitates subsequent fault tracking and troubleshooting, thus overcoming the deficiencies of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A circuit board power-on testing device includes a base, a platform at the top of the base, a support frame at the upper end of the platform, a lifting platform on the inner wall of the support frame, a pressing component connected to the lifting platform, a probe on the lifting platform, a test interface on one side of the base, the test interface and the probe being connected by wires, and a communication interface on the rear panel of the base.

[0007] As a further improvement of this utility model: a display screen and a power switch are provided on one side of the base, and the communication interface and the display screen are both electrically connected to the test interface.

[0008] As a further improvement of this utility model, a placement groove is provided at the top of the base and inside the support frame.

[0009] As a further embodiment of this utility model: the pressing component includes a U-shaped plate fixed to the top of the lifting platform, a guide rod is provided at the top of the horizontal section of the U-shaped plate, the guide rod is movably inserted into the top of the support frame, and a handle is provided at the top of the guide rod.

[0010] As a further improvement of this utility model: vertical rods are provided at the top of the shelf and on both sides of the placement slot, and the two ends of the lifting platform are respectively inserted into the two vertical rods, and springs are sleeved at the bottom of the two vertical rods.

[0011] As a further improvement of this utility model, the top of the shelf and the base are connected by a fixing buckle.

[0012] As a further improvement of this utility model: a wire hole is provided on one vertical section of the support frame, and the wire passes through the wire hole.

[0013] The beneficial effects of this utility model are as follows: 1. No need for manual point-by-point measurement with a multimeter. Multiple test points are contacted simultaneously by probes, which solves the problem of short circuits between adjacent points that are easy to occur during manual testing, shortens the testing time of a single module, and avoids missed tests, insufficient tests, and accidental contact. At the same time, the host computer can automatically generate a data table in a fixed format, which is convenient for subsequent fault tracking and troubleshooting.

[0014] 2. The pressing component, in conjunction with the spring, enables precise probe contact. The fixing buckle ensures that the platform and the base are fastened together and that the product under test is level. The wire holes assist in the compact arrangement of the wires. The display screen can also display the current operating current of the test board in real time. The operation is convenient and the structure is stable. Attached Figure Description

[0026] The operator places the PCB board to be tested into the placement slot 14 of the platform 4 in a fixed direction. The operator then presses down the guide rod 10 using the handle 7. The guide rod 10 pushes the U-shaped plate 13 and the lifting platform 6 to move down, so that the probe 5 is connected to the potential of the PCB board. At this time, the spring 17 is compressed. The host computer is connected to the test motherboard through the communication interface. The voltage values ​​of each test point measured by the motherboard and the short circuit / continuity status are transmitted to the host computer software through the communication interface. The host computer automatically generates a data table in a fixed format according to the set parameters, which is convenient for subsequent tracking and troubleshooting of fault information. The display screen 8 can display the working current of the test board in its current working state. After the test is completed, release handle 7. Under the rebound action of spring 17, push lifting platform 6 to move probe 5 away from PCB board, and then the PCB board can be removed.
