Description

Technical Field

[0001] This invention relates to the technical field of test modules, and in particular to an automatic test module for high-current power supplies. Background Technology

[0002] For high-current, high-voltage electrical equipment, the circuit board needs to be connected to a high-current power supply connector during operation. However, the traditional connection method usually involves connecting a set of PCBA adapter boards on the test equipment to the power supply connector, and then the adapter board is connected to the product under test (DUT) to supply power. To ensure reliable connection, a PCBA adapter board needs to be specially designed for the DUT to ensure that the adapter board can withstand the current during testing. However, this connection method not only occupies a lot of space, but also has high material costs for carrying high current.

[0003] If an automated test module that offers fast connectivity, reliable electrical performance, and low cost can be provided, the aforementioned technical problems can be effectively solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic test module for high current power supplies that is fast to connect, ensures reliable electrical performance, and is low in cost.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a mounting plate, a test power supply connector, and at least one pair of connecting components. The connecting components include a connecting terminal, an isolation connecting sleeve, and a mating terminal. The connecting terminal is connected to the test power supply connector. One end of the mating terminal is fixedly connected to the connecting terminal. The other end of the mating terminal is provided with a mating groove that mates with the terminal of the circuit board under test. The isolation connecting sleeve is fixed on the mounting plate, and the mating terminal is floatingly disposed within the isolation connecting sleeve.

[0006] As can be seen from the above solution, the isolation connecting sleeve acts as a bridge between the test power supply connector and the circuit board under test (PCB), ensuring that the test power supply connector is effectively supported during testing and guaranteeing its stability and reliability with the PCB during testing. Simultaneously, the isolation connecting sleeve isolates the connecting terminals, mating terminals, and mounting plate, thereby preventing the high current path during testing from affecting other test components. This allows the mounting plate to be made of other materials or use a standard PCBA, thus avoiding the power supply components occupying a large space and reducing equipment costs. The floating design ensures that the PCB and its terminals are not damaged during connection.

[0007] In a preferred embodiment, the isolation connecting sleeve is provided with a movable cavity adapted to the docking terminal, a floating spring is provided in the movable cavity, the floating spring is sleeved on the docking terminal, the docking terminal is provided with a first limiting step, and the two ends of the floating spring respectively cooperate with the end wall of the movable cavity and the first limiting step.

[0008] A preferred embodiment is that a limiting boss is provided on the outer side of the isolation connecting sleeve, and the limiting boss cooperates with the mounting plate for limiting.

[0009] A further preferred embodiment is that the mating terminal is also provided with a second limiting step that cooperates with the limiting boss. Attached Figure Description

[0010] Figure 1 This is a three-dimensional structural schematic diagram of the present invention; Figure 2 This is a cross-sectional view of the present invention; Figure 3 This is an exploded structural diagram of the present invention. Detailed Implementation

[0011] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a mounting plate 1, a test power connector 2, and at least one pair of connecting components. The connecting components include a connecting terminal 3, an isolation connecting sleeve 4, and a mating terminal 5. The connecting terminal 3 is connected to the test power connector 2. One end of the mating terminal 5 is fixedly connected to the connecting terminal 3. The other end of the mating terminal 5 is provided with a mating groove 6 that mates with the terminal of the circuit board under test. The isolation connecting sleeve 4 is fixed on the mounting plate 1, and the mating terminal 5 is floatingly disposed within the isolation connecting sleeve 4.

[0012] like Figure 2 As shown, in this embodiment, the isolation connecting sleeve 4 is provided with a movable cavity 7 adapted to the docking terminal 5. A floating spring 8 is disposed within the movable cavity 7 and is sleeved on the docking terminal 5. The docking terminal 5 is provided with a first limiting step 9. The two ends of the floating spring 8 respectively cooperate with the end wall of the movable cavity 7 and the first limiting step 9. The movable cavity 7 and the floating spring 8 provide buffering for the connecting assembly. During the test docking process, after the docking terminal 5 contacts the terminal of the circuit board under test, it receives a force that compresses the floating spring 8, thereby absorbing the impact force and reducing the impact force on the mounting plate 1 and the equipment structure.

[0013] like Figure 2 and Figure 3As shown, in this embodiment, a limiting boss 10 is provided on the outer side of the isolation connecting sleeve 4, and the limiting boss 10 is in a limiting engagement with the mounting plate 1. The docking terminal 5 is also provided with a second limiting step 11 that engages with the limiting boss 10. The limiting boss 10 and the mounting plate 1 are designed to ensure accurate installation. Simultaneously, the engagement of the limiting boss 10 and the second limiting step 11 restricts the travel of the docking terminal 5, preventing it from being pushed beyond the device's travel range when aligning with the circuit board under test.

[0014] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
