Description

Technical Field

[0001] This utility model relates to a flexible test connector module mechanism, belonging to the field of installation equipment technology. Background Technology

[0002] Printed circuit boards (PCBs) are the support structures for electronic components and the basic carriers for circuit connections. PCBA overall testing is a testing process that verifies the functionality and reliability of printed circuit board assemblies. Current PCBA testing includes steps such as program burning, ICT online testing, FCT functional testing, and aging testing.

[0003] Currently, PCBA electrical performance verification testing uses testing equipment connected to the PCB board via test connector modules to obtain circuit parameters and perform functional verification testing. Existing test connector module structures are large, integrating multiple test connectors into a single unit. During PCB board connection testing, issues arise such as misalignment, inaccurate positioning, or insufficient connector length leading to non-contact. Since individual integrated test connectors lack adjustability, continuous adjustments are needed to find the optimal insertion / removal position to ensure proper connection. Therefore, a new test connector module mechanism is needed to address the problems of large size, space consumption, difficult connection and debugging, and long testing cycles associated with existing integrated test connector structures used in PCBA electrical performance testing. Utility Model Content

[0004] The purpose of this invention is to provide a flexible test connector module mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible test connector module mechanism, including a mounting base, a test connector assembly, and a connector. The test connector assembly includes several sub-test connectors, which are mounted on the mounting base via connectors, and the sub-test connectors can be adjusted in any direction relative to the mounting base via connectors.

[0006] Specifically, the mounting base includes a base and a connecting base. The number of connecting bases is consistent with the number of sub-test connectors, and the connecting bases and sub-test connectors are set in a one-to-one correspondence. The sub-test connectors are installed on the connecting bases, and the connecting bases are installed on the mounting bases through connectors.

[0007] Specifically, the sub-test connector includes a test connector and a rotating plate; the test connector is installed on the rotating plate and is electrically connected to the rotating plate; the rotating plate is fixedly installed on the connector base.

[0008] Specifically, the rotating plate has threaded holes, and the connecting seat has screw holes at corresponding positions; the rotating plate is installed on the connecting seat by connecting screws passing through the screw holes and being threadedly connected to the threaded holes of the rotating plate.

[0009] Specifically, the connector has an internal mounting groove that runs through the body. The rotating plate is installed in the mounting groove, and its two ends extend to the outside of the mounting groove to form two extended ends. Test connectors are electrically connected to the extended ends for connecting test equipment and the device under test.

[0010] Specifically, the connector includes a connecting bolt and a spring; the base has several mounting holes, and the connector has a connecting hole at a position corresponding to the mounting holes, with an internal thread inside the connecting hole. The connector is installed on the base by the connecting bolt passing through the mounting hole and the internal thread of the connecting hole to form a threaded connection, and a spring is fitted on the connecting bolt between the connector and the base.

[0011] Specifically, one end of the spring abuts against the connecting hole of the connecting seat, and the other end abuts against the base body facing the connecting seat; under the elastic action of the spring, there is a gap between the connecting seat and the base.

[0012] Specifically, the outer diameter of the connecting bolt is smaller than the diameter of the mounting hole.

[0013] Specifically, the connecting bolts are equal-height bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application uses several sub-test connectors, which are mounted on the mounting base via connectors. The sub-test connectors can be adjusted in any direction relative to the mounting base via the connectors. Using a single sub-test connector reduces the overall module structure and space required. The flexible connection of a single test connector via connectors allows for flexible adjustment of the test connector position, effectively shortening the debugging time for test connector mating.

[0015] 2. Based on the foregoing, the mounting base of this application includes a base and a connecting base. Sub-test connectors are correspondingly arranged one-to-one with the connecting bases, and the connecting bases are mounted to the base via connectors. This allows for the selection of appropriate connecting bases and mounting sub-test connectors according to test requirements and the specifications of the test connectors of the test piece. This facilitates adjustment of the connecting base's mounting position on the base, and further enables pre-design of the mounting positions between sub-test connectors, optimizing the insertion and removal positions of the sub-test connectors and improving the docking efficiency of the test connectors.

[0016] 3. Based on the foregoing, the sub-test connector of this application includes a test connector and a rotating plate; the test connector is mounted on the rotating plate and is electrically connected to the rotating plate. The rotating plate has threaded holes, and the connecting seat has screw holes at corresponding positions; the rotating plate is mounted to the connecting seat by connecting screws passing through the screw holes and threadedly connecting to the threaded holes of the rotating plate. This application reduces the number of connecting wires by using a rotating plate to connect the test connector, further reducing the footprint of the flexible test connector module mechanism.

[0017] 4. Building upon the foregoing, the connector of this application features an internal mounting groove penetrating the connector body. A rotating plate is mounted in the mounting groove, with both ends extending outwards to form two extended ends. Test connectors are electrically connected to these extended ends for connecting the test equipment and the device under test (DUT). This design allows the rotating plate to penetrate the connector, forming extended ends on both sides for mounting test connectors, resulting in a smaller footprint. Furthermore, the connector serves as the interface between the test equipment and the DUT, enabling rapid mating of corresponding test connectors. During batch testing, only the test connectors of the test equipment need to be aligned before repeated insertion and removal tests can be performed, saving on repetitive positioning and mating operations and improving testing efficiency.

[0018] 5. Based on the foregoing, the connector of this application includes a connecting bolt and a spring. The connecting bolt is used to connect the mounting base and the connecting base. The spring is sleeved on the connecting bolt, with one end of the spring abutting against the connecting hole of the connecting base and the other end abutting against the seat body of the mounting base facing the connecting base. Under the elastic action of the spring, a gap is left between the connecting base and the mounting base. This allows the connecting base to be adjusted relative to the mounting base along the axial direction of the connecting bolt under the elastic action of the spring. This compensates for the interface alignment accuracy between the rotating plate test connector and the test connector of the device under test during test connector docking, thereby reducing the docking difficulty. The outer diameter of the connecting bolt of this application is smaller than the diameter of the mounting hole, leaving an installation gap between the connecting bolt and the mounting hole. This allows the connecting base to be adjusted relative to the mounting base in any direction, which also compensates for the interface alignment accuracy and improves the docking efficiency of the test connector.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] Please see Figures 1-4 This embodiment discloses a flexible test connector module mechanism, including a mounting base 1, a test connector assembly 2, and a connector. The test connector assembly includes five sub-test connectors 3. The sub-test connectors are mounted on the mounting base 1 through the connector, and the sub-test connectors can be adjusted in any direction relative to the mounting base through the connector.

[0023] The mounting base in this embodiment includes a base 4 and a connecting base 5. The number of connecting bases is consistent with the number of sub-test connectors, and the connecting bases and sub-test connectors are arranged in a one-to-one correspondence. The sub-test connectors in this embodiment include test connectors 6 and a rotating plate 7. The test connectors are mounted on the rotating plate and are electrically connected to the rotating plate. The rotating plate is fixedly mounted on the connecting base.

[0024] Preferably, the rotating plate 7 in this embodiment is provided with a threaded hole 70, and the connecting seat 5 is provided with a screw hole 50 at a position corresponding to the threaded hole; the rotating plate is installed on the connecting seat by means of a connecting screw (not shown) passing through the screw hole and being threadedly connected to the threaded hole of the rotating plate.

[0025] Furthermore, in this embodiment, the connector 5 has an internal mounting groove that penetrates the connector body. The rotating plate is installed in the mounting groove, and its two ends extend to the outside of the mounting groove to form two extended ends. Test connectors are electrically connected to the extended ends for connecting test equipment and the PCB board under test.

[0026] The connector in this embodiment includes a connecting bolt 8 and a spring 9. Four mounting holes are provided on the base corresponding to each connecting seat. A connecting hole is provided on the connecting seat corresponding to each mounting hole, and the connecting hole has an internal thread. The connecting seat is installed on the base via a threaded connection formed by the connecting bolt passing through the mounting hole and the internal thread of the connecting hole. A spring is fitted onto the connecting bolt between the connecting seat and the base. In this embodiment, one end of the spring abuts against the connecting hole of the connecting seat, and the other end abuts against the base body facing the connecting seat. A gap is maintained between the connecting seat and the base due to the elastic action of the spring. Furthermore, the outer diameter of the connecting bolt in this embodiment is smaller than the diameter of the mounting hole. Preferably, the connecting bolt in this embodiment is a constant-height bolt.

[0027] Working Principle: In this embodiment, the flexible test connector module mechanism is used by the operator who first determines the appropriate number and size of sub-test connectors based on the PCB board specifications and the test connector dimensions. The sub-test connectors are then installed on the mounting base. Before testing, the operator aligns the turntable with the test connector of the PCB board to be tested, inserts the turntable into the mounting slot of the connector base, adjusts the installation height, and secures it to the connector base with connecting bolts. Next, the test connector on the other side of the turntable is aligned with the test point of the PCBA testing equipment.

[0028] During testing, the testing equipment uses test connectors on the turntable to test the PCB board under test. After testing, a new PCB board is replaced. When reconnecting the test connectors, the turntable is fixedly mounted on the connector base, and the test connectors on the testing equipment side do not need to be removed. Only the test connectors on the device under test side need to be repeatedly plugged and unplugged for testing, saving the time spent on plugging and unplugging the test connectors on one side. During the test connector docking process, the equal-height bolts and springs between the connector base and the base can compensate for the docking accuracy between the turntable test connector and the PCB board test connector. Only a rough adjustment is needed for easy positioning, effectively shortening the test connector docking and debugging time.

For those skilled in the art, after learning the contents of the present invention, several equivalent changes and substitutions can be made without departing from the principle of the present invention. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present invention.
