Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and specifically provides a DC detection device for optical devices. Background Technology

[0002] After production, optical devices need to undergo testing to determine their various data. This testing includes DC testing and RF testing. DC testing requires connecting a testing circuit board to the optical device to test different functions, such as power supply (DC / DC), control unit (MCU), digital-to-analog converter (ADC, DAC), temperature control (TEC), high voltage testing (APD), backlight testing (PD, IMPD), and dark current testing (IDARK).

[0003] However, to achieve the above-mentioned detection functions, the usual practice is to embed these circuits as functional circuits into the circuit board, that is, to directly copy the circuits and lines. But this approach has a problem: if part of the circuit board is damaged, the entire circuit board is discarded. Even if other circuits are normal, not all components can be reused, resulting in waste. Utility Model Content

[0004] This invention provides a DC detection device for optical devices, which solves the problem of waste caused by the failure of one detection circuit in a DC detection circuit, rendering the entire circuit board unusable.

[0005] The technical solution of this utility model is as follows:

[0006] A DC detection device for optical devices includes a main circuit board and a functional module. The functional module is provided with a detection circuit. The main circuit board is provided with a socket and pins. The functional module is electrically connected to the main circuit board through the socket. The functional module and the socket are detachably connected. The pins are used to connect to the optical device to be detected.

[0007] In this solution, the detection circuit in the functional module is independent of the circuit on the main circuit board. Damage to the detection circuit of a functional module will not affect the circuit on the main circuit board. Furthermore, since the functional modules are detachably connected to the main circuit board via sockets, even if a functional module malfunctions, causing damage to its detection circuit, the circuit on the main circuit board will not be affected because the circuits on the functional module are independent. In this case, it is only necessary to detach the functional module from the socket and replace it with a new one, without rendering the entire circuit board unusable, thus reducing costs and waste.

[0008] Optical devices include several DC testing items. If the functional module is replaced for each DC testing item, the operation becomes cumbersome. Therefore, the DC testing device of this application includes at least two functional modules, each with a different testing circuit. The main circuit board has at least two sockets.

[0009] In this solution, all the necessary functional modules can be prepared before testing, and then each functional module can be connected to the socket on the main circuit board. After the test of a DC test item is completed, the next functional module can be used directly for the next test without removing the functional modules in the middle of the test, thus reducing the complexity of the operation.

[0010] The detection device of this utility model also includes a controller, which is electrically connected to the main circuit board.

[0011] In this solution, the controller enables high-frequency, multi-parameter, and repeatable detection, which can improve the factory's detection efficiency.

[0012] To address the issue of functional modules becoming detached from the socket due to unstable positioning, the main circuit board is equipped with a mounting plate, and the functional modules are connected to the mounting plate.

[0013] In this solution, the functional module is connected to the mounting plate, which fixes the position of the functional module and prevents it from shifting during the testing process and becoming detached from the socket.

[0014] Preferably, the mounting plate is provided with a mounting slot for mounting functional modules.

[0015] In this solution, the installation module is installed in the mounting slot. The installation module can be simply inserted into the mounting slot, making the installation operation convenient and simple.

[0016] To address the issue of the mounting module being difficult to insert due to incorrect insertion during processing at the corner of the mounting slot, process holes are provided at the corner of the mounting slot.

[0017] In this design, process holes are provided at the corners of the mounting slots so that the corners of the functional modules can be accommodated in the process holes, thus avoiding the inability to install the functional modules into the mounting slots due to defects such as burrs on the edges.

[0018] Preferably, the mounting plate is fixed to the main circuit board by fasteners.

[0019] To reduce the installation space of the functional modules, the bottom of the mounting slot is provided with a through hole, and the socket is located below the through hole.

[0020] In this design, the socket is located below the through hole at the bottom of the mounting slot. If a cable is installed on the functional module, one end of the cable has a plug that connects to the socket. After installation, the plug and cable are located below the functional module. Therefore, the space required for installing the functional module will not exceed the size of the mounting slot. The size of the mounting slot is compatible with the functional module, ensuring that the installation space for the functional module is compatible with its own size. This prevents the plug from occupying extra space due to needing to connect to sockets in other locations, reducing the space required for installing functional modules and facilitating the installation of more functional modules.

[0021] Preferably, the mounting plate is provided with at least two mounting slots.

[0022] In this design, at least two mounting slots are provided, which can fix each functional module when there is more than one functional module connected to the main circuit board.

[0023] Preferably, the functional module is provided with a plug that connects to the socket, and the plug is connected to the detection circuit on the functional module via a cable.

[0024] In this solution, the cable can be fully secured, and after the plug and socket are connected, it is easy to fix the functional module or place it in other locations, thus facilitating the fixation of the functional module.

[0025] The beneficial effects of this utility model are:

[0026] This invention separates various detection circuits from the main circuit board. The detection circuits are set in the functional modules, which are detachably connected via sockets on the main circuit board. When a detection circuit malfunctions, the functional module can be replaced without affecting other functional modules or the main circuit board. Attached Figure Description

[0032] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.

[0033] Example 1:

[0034] like Figure 1 As shown, this embodiment provides a DC detection device for optical devices, including a main circuit board 1 and functional modules 7. The main circuit board is provided with general circuits required for the operation of various detection circuits, and each functional module 7 is provided with a detection circuit. The main circuit board 1 is provided with a socket 5 for connecting to the functional modules 7, and the functional modules 7 are provided with a plug 8 for connecting to the socket 5. The socket 5 is electrically connected to the circuit on the main circuit board 1, and the plug 8 is electrically connected to the detection circuit on the functional module 7. When the socket 5 and the plug 8 are connected, the detection circuit on the functional module 7 is electrically connected to the circuit on the main circuit board 1.

[0035] The main circuit board 1 contains general-purpose circuits, such as power management circuits, basic signal acquisition and ADC, protection and monitoring circuits, etc.

[0036] The circuits on functional module 7 include optical power detection circuits, signal conditioning circuits, etc.

[0037] The circuits on the main circuit board 1 and the functional module 7 described above are only a few of the many circuits listed as examples in this embodiment. Those skilled in the art should understand that there are many existing DC detection circuits, and each DC detection circuit can be set on the main circuit board 1 or the functional module 7 respectively.

[0038] The main circuit board 1 is also provided with pins for connecting to optical devices. After the pins are connected to the optical devices, the data of the main circuit board 1 and each functional module 7 can be transmitted from the pins to the optical devices or other circuits.

[0039] like Figure 2 As shown, functional module 7 is equipped with a plug 8 for connecting to socket 5. The plug 8 and the detection circuit on functional module 7 can be connected via a cable 9. One end of cable 9 connects to the detection circuit on functional module 7, and the other end connects to the plug 8. Because cable 9 is flexible, it is easier to connect to socket 5. After the plug 8 is connected to socket 5, the flexibility of cable 9 allows functional module 7 to be moved to other locations for fixing or placement.

[0040] This embodiment also includes a mounting plate 2, which is fixedly connected to the main circuit board 1 and is used to install the functional module 7.

[0041] The mounting plate 2 is provided with mounting slots 3, the size and shape of which are adapted to the size and shape of each functional module 7, so that the functional module 7 can be inserted into the mounting slot 3. The opening of the mounting slot 3 faces upward, and the functional module 7 is placed into the mounting slot 3 from the top. The side wall of the mounting slot 3 is in contact with the side of the functional module 7, and the side wall of the mounting slot 3 clamps the functional module 7 with friction, preventing the functional module 7 from falling out of the mounting slot 3.

[0042] Functional module 7 is a separate circuit board with an overall rectangular shape, and the mounting slot 3 is also rectangular. The mounting slot 3 has four corners, each with a process hole 6. The axis of the process hole 6 coincides with the endpoints of the four corners. When there are burrs or other protruding defects at the corners of functional module 7, the process holes 6 ensure that functional module 7 can be installed into the mounting slot 3. The function of the process holes 6 is to prevent functional module 7 from being unable to be installed into the mounting slot 3 due to burrs or other defects at the corners.

[0043] Mounting plate 2 is fixedly connected to main circuit board 1 by fasteners. Fasteners can be screws or bolts. Since capacitors and other components need to be mounted on main circuit board 1, to prevent mounting plate 2 from pressing against these components, a support rod 10 is provided on the side of mounting plate 2 connected to main circuit board 1. The support rod 10 has a through hole 4. The main support plate has threaded holes for screws. The screws pass through the through hole 4 on the support rod 10 and connect to the threaded holes. The support rod 10 supports mounting plate 2, creating a gap between mounting plate 2 and main circuit board 1, thus preventing mounting plate 2 from pressing against the components on main circuit board 1.

[0044] The mounting slot 3 has a through hole 4 at its bottom, and the socket 5 is located below the through hole 4. When installing the functional module 7, first connect the plug 8 to the socket 5, then bend the cable 9 so that it folds below the through hole 4, and then place the functional module 7 into the mounting slot 3. The sidewalls of the mounting slot 3 secure the functional module 7 with friction, preventing it from detaching.

[0045] The number of mounting slots 3 can be one, two, three, or more. The main circuit board 1 has multiple sockets 5, each socket 5 used to connect to a different functional module 7. Depending on the optical device being tested, the testing items will differ, allowing for the replacement of the functional modules 7 connected to each socket 5. Each functional module 7 is installed in its respective mounting slot 3. The mounting plate 2 has multiple mounting slots 3 to ensure that each functional module 7 can be securely fixed.

[0046] Example 2:

[0047] This second embodiment provides a DC detection device for optical devices. Unlike the first embodiment, this second embodiment also includes a controller.

[0048] The controller is electrically connected to the main circuit board 1. The controller can be a PLC or a microcontroller. The controller can be fixed to the main circuit board 1 by soldering.

[0049] The controller is responsible for controlling the operation of each functional module 7 to meet the factory's needs for high-frequency, multi-parameter, and repeatable detection.

[0050] If only a limited number of tests are required, the power supply can be manually adjusted and data recorded, eliminating the need for a controller. However, factories produce a large number of optical devices, necessitating extensive testing. Therefore, configuring a controller can improve testing efficiency and reduce the workload of operators.
