Description

Technical Field

[0001] This utility model relates to the field of test fixture technology, specifically to a front probe pressing module for a test fixture. Background Technology

[0002] Product power-on testing is a crucial step in ensuring product quality and performance. It verifies whether the product can function normally when powered on, including whether the light-emitting function is turned on correctly, whether the brightness is uniform, and whether the color is accurate. It also checks for electrical faults such as short circuits, open circuits, and leakage, and assesses the product's stability and reliability to ensure that no abnormalities occur during long-term use.

[0003] In existing technologies, when conducting power-on tests on products, it is necessary to manually connect the test module and the product's conductive busbars to perform the power-on test. However, existing connections are often made manually by plugging and unplugging each other, which not only leads to low overall work efficiency, but also introduces certain connection errors, affecting the overall power-on test results. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a front probe pressing module for a test fixture, so as to solve the technical problem that in the prior art, manual interlocking is often used, which not only leads to low overall work efficiency, but also causes certain connection errors due to manual connection, affecting the overall power-on testing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a front probe pressing module for a test fixture, comprising a base, wherein a flip cover is rotatably connected to the top of the base and therebetween, wherein one end of the flip cover and the base are rotatably connected by a rotating shaft connecting rod, and one end of the flip cover is provided with a rotating shaft hole that cooperates with the rotating shaft connecting rod.

[0006] The flip cover is provided with a probe holder inside. Multiple sets of probe heads corresponding to the product's conductive wires are evenly fixed at the bottom of the probe holder. A placement groove is opened at the middle of one end of the top of the base. A second magnet is provided on both sides inside the base. A first magnet that is attracted to the second magnet is provided on both sides inside the flip cover.

[0007] The base and the flip cover have grooves on both sides inside that mate with the first magnet and the second magnet, and the grooves, the first magnet and the second magnet have circular cross-sections.

[0008] The flip cover has an internal mounting groove that mates with the probe holder. A circuit board located above the probe holder is fixed inside the mounting groove. The circuit board and the probe head are electrically connected, and the circuit board is connected to an external power supply device via wires.

[0009] By adopting the above technical solution, when the product needs to be powered on for testing, the conductive wires of the product are placed inside the placement slot. Then, the flip cover is flipped open by holding the handle and closed with the base. At this time, the probe seat inside the flip cover drives the probe head to press and connect the conductive wires of the product, thereby enabling the product's conductive wires to be connected for lighting test. At the same time, when the flip cover is closed relative to the base, the first magnet of the flip cover and the second magnet of the base attract each other with opposite polarities, thus ensuring the stability of the flip cover after it is closed and providing a pressing force for the product's conductive wires. The overall operation is relatively convenient and effectively avoids the problem of connection errors caused by manual connection.

[0010] Furthermore, guide posts are fixed on both sides of the top of the base, and guide holes that cooperate with the guide posts are opened on both sides of the inside of the flip cover.

[0011] By adopting the above technical solution, the cooperation of the guide post and guide hole provides accuracy after the flip cover and base are closed, ensuring that the probe head can be aligned with the product's conductive line bar, resulting in better testing results.

[0012] Furthermore, a handle is fixed to the top of the flip cover, and a rubber ring is fixed to the outside of the handle.

[0013] By adopting the above technical solution, the handle facilitates the opening and closing of the flip cover by the staff, making the overall operation more convenient.

[0014] In summary, this utility model has the following beneficial effects: When the product needs to be powered on for testing, the conductive wires of the product are placed inside the placement slot, and then the flip cover is flipped open and closed with the base by holding the handle. At this time, the probe seat inside the flip cover drives the probe head to press and connect the conductive wires of the product, thereby enabling the product's conductive wires to be connected for lighting test. At the same time, when the flip cover is closed relative to the base, the first magnet of the flip cover and the second magnet of the base attract each other with opposite polarities, thereby ensuring the stability of the flip cover after it is closed and providing a pressing force for the product's conductive wires. The overall operation is relatively convenient and effectively avoids the problem of connection errors caused by manual connection. Attached Figure Description

[0022] A test fixture front probe pressing module, such as Figure 1-4 As shown, it includes a base 1, and a flip cover 2 that rotatably connects to the top of the base 1. The flip cover 2 and the base 1 are rotatably connected at one end by a rotating shaft connecting rod 8, and a rotating shaft hole that mates with the rotating shaft connecting rod 8 is provided at one end of the flip cover 2.

[0023] Inside the flip cover 2, there is a probe seat 5. At the bottom of the probe seat 5, there are multiple sets of probe heads 6 that correspond to the conductive wires of the product. A placement groove 7 is opened at the middle of one end of the top of the base 1. The second magnet 13 is set on both sides inside the base 1. The first magnet 9 that is attracted to the second magnet 13 is set on both sides inside the flip cover 2.

[0024] When it is necessary to conduct a power-on test on the product, place the product's conductive wires inside the placement slot 7, and then hold the handle 12 to flip the flip cover 2 and close it with the base 1. At this time, the probe seat 5 inside the flip cover 2 drives the probe head 6 to press and connect the product's conductive wires, so that the product's conductive wires can be connected for a lighting test.

[0025] Meanwhile, when the flip cover 2 is closed relative to the base 1, the first magnet 9 of the flip cover 2 and the second magnet 13 of the base 1 attract each other with opposite polarities, thereby ensuring the stability of the flip cover 2 after it is closed and providing a pressing force on the product's wire harness. The overall operation is relatively convenient and effectively avoids the problem of connection errors caused by manual connection.

[0026] The base 1 and the flip cover 2 are respectively provided with grooves 10 on both sides inside to cooperate with the first magnet 9 and the second magnet 13. The grooves 10 facilitate the installation and fixing of the magnets, and the cross-sections of the grooves 10, the first magnet 9 and the second magnet 13 are circular.

[0027] The flip cover 2 has an internal mounting groove 3 that mates with the probe base 5. The mounting groove 3 has a circuit board 4 fixed inside, located above the probe base 5.

[0028] Please see Figure 1 and Figure 4 The base 1 has guide posts 11 fixed on both sides of the top, and the flip cover 2 has guide holes 14 on both sides of the interior that cooperate with the guide posts 11. By setting the above structure, the cooperation of the guide posts 11 and the guide holes 14 provides the accuracy of the flip cover 2 and the base 1 after they are closed, ensuring that the probe head 6 can be aligned with the conductive line of the product, thus making the test effect better.

[0029] Please see Figure 1 and Figure 4 The top of the flip cover 2 is fixed with a handle 12, and a rubber ring is fixed on the outside of the handle 12. By setting the above structure, the handle 12 facilitates the operation of the flip cover 2 by the staff, and the overall operation is more convenient.

[0030] The working principle of this utility model is as follows: When in use, the power supply is turned on, so that the external power supply is electrically connected to the probe head 6 of the probe base 5 through the wire.

[0031] When it is necessary to conduct a power-on test on the product, place the product's conductive wires inside the placement slot 7, and then hold the handle 12 to flip the flip cover 2 and close it with the base 1. At this time, the probe seat 5 inside the flip cover 2 drives the probe head 6 to press and connect the product's conductive wires, so that the product's conductive wires can be connected for a lighting test.

[0032] Meanwhile, when the flip cover 2 is closed relative to the base 1, the first magnet 9 of the flip cover 2 and the second magnet 13 of the base 1 attract each other with opposite polarities, thereby ensuring the stability of the flip cover 2 after it is closed and providing a pressing force on the product's wire harness. The overall operation is relatively convenient and effectively avoids the problem of connection errors caused by manual connection.

[0033] Furthermore, guide posts 11 are fixed on both sides of the top of the base 1. After the flip cover 2 is closed, the guide posts 11 can be inserted into the guide holes 14 inside the flip cover 2, which ensures the overall positioning accuracy and provides the accuracy of the overall test.
