Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, specifically to a tooling for testing insertion and extraction force. Background Technology

[0002] In the fields of electronic connectors, plugs, and semiconductors, pins and inserts are core components of electrical connections. The insertion and extraction force of their clamps directly affects the reliability, service life, and operational safety of the equipment. The insertion and extraction force of pin clamps must meet specific standards. Excessive insertion and extraction force can lead to inconvenience in operation or damage to components, while insufficient force may cause poor contact, signal interruption, or even safety hazards such as short circuits. Therefore, accurate testing of the insertion and extraction force of pin clamps is a key step in product development, production quality inspection, and performance optimization, and insertion and extraction force testing fixtures are often used.

[0003] In existing technologies, spring balances are generally used to test the insertion and extraction force of pins. However, when fixing the pins, the spring balance is not easy to fix, resulting in large errors during testing. Furthermore, it is not convenient to quickly install the overall testing fixture, making it susceptible to collisions and other external factors that can damage the testing fixture, thereby affecting the data of subsequent tests and hindering its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tooling for testing insertion and extraction force, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a tooling for testing insertion and extraction force, including a processor, a device housing, a force sensor, a chuck body, and a limiting sleeve threadedly connected to the chuck body. The device housing is composed of a bottom plate, a side plate, a back plate, and a top plate. The bottom plate has a positioning hole 1 through it at the end near the force sensor. The side plate has a positioning hole 2 through it at the end near the force sensor. The top plate has a positioning hole 3 through it at the end near the force sensor. The positioning holes 1, 2, and 3 are compatible. A positioning bolt 1 is threadedly connected to the inner surface of the positioning holes 1, 2, and 3.

The side plate has a slot at the end near the processor that is plugged into the limit block.

[0007] Through the above technical solution, the groove and the side plate are matched to form an "L-shaped" splicing structure, which ensures that the bottom plate and the side plate are vertically positioned, improves the overall rigidity of the equipment shell, and the insertion and matching of the limiting block and the first slot can limit the displacement of the processor in the horizontal direction, avoid the electrical connection between the processor and the side plate being loosened due to vibration, and at the same time provide lateral support for the processor to ensure its stability during the testing process.

[0008] Preferably, an electronic force value digital display is fixedly installed on one end of the processor, and a second slot is opened on the side plate near the first slot to abut against the electronic force value digital display.

[0009] Through the above technical solution, the size of slot 2 is precisely matched with the electronic force value digital display, forming a rigid limiting structure to prevent the display screen from tilting or falling off due to external force collision or equipment movement.

[0012] Preferably, the end of the mounting frame furthest from the processor is threaded with a second positioning bolt that penetrates the mounting frame and extends into it, and the two ends of the back plate furthest from the center line are fixedly installed with a locking block that matches the first locking slot.

[0013] Through the above technical solution, the cooperation between the card block and the card slot one enables the rapid installation of the backplate, forming rear protection for the processor. At the same time, together with the bottom plate, side plate, and top plate, it forms a closed cavity to isolate external dust and moisture from corroding the internal circuitry.

[0014] Preferably, a plurality of heat dissipation fins are fixedly installed at the end of the mounting frame away from the processor, and a plurality of heat dissipation holes with equal spacing are opened through one end of the back plate, and the heat dissipation fins are made of aluminum alloy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: As Figure 1-8 As shown, the present invention provides a tooling for testing insertion and extraction force, including a processor 6, a device housing, a force sensor 24, a chuck body 25, and a limiting sleeve 26 threadedly connected to the chuck body 25. The device housing is composed of a base plate 1, a side plate 13, a back plate 17, and a top plate 20. A positioning hole 3 is provided through the end of the base plate 1 near the force sensor 24. A positioning hole 16 is provided through the end of the side plate 13 near the force sensor 24. A positioning hole 21 is provided through the end of the top plate 20 near the force sensor 24. The positioning holes 1, 2, and 3 are adapted to each other. A positioning bolt 5 is threadedly connected to the inner surface of the positioning holes 1, 2, and 3. A positioning hole 4 22 is provided at the end of the top plate 20 near the force sensor 24. The top plate 20 is adapted to the force sensor 24 through the positioning hole 4 22.

[0033] Specifically, a groove 2 adapted to the side plate 13 is provided on the outer edge of the end of the base plate 1 near the force sensor 24. Limiting blocks 7 are fixedly installed on both ends of the processor 6 away from the center line. A slot 14 for plugging into the limiting block 7 is provided on the end of the side plate 13 near the processor 6. The advantage is that the groove 2 and the side plate 13 form an "L-shaped" splicing structure, ensuring that the base plate 1 and the side plate 13 are vertically positioned, improving the overall rigidity of the equipment shell. The plugging into the limiting block 7 and the slot 14 can limit the horizontal displacement of the processor 6, preventing the electrical connection between the processor 6 and the side plate 13 from loosening due to vibration. At the same time, it provides lateral support for the processor 6, ensuring its stability during the test.

[0034] Specifically, an electronic force value digital display 8 is fixedly installed on one end of the processor 6, and a second slot 15 is opened on the side plate 13 near the slot 14 to abut against the electronic force value digital display 8. The advantage is that the size of the second slot 15 is precisely matched with the electronic force value digital display 8 to form a rigid limiting structure, which prevents the display screen from tilting or falling off due to external force collision or equipment movement. The abutting design between the digital display 8 and the side plate 13 can disperse the impact load on the display screen.

[0035] Specifically, positioning seats 4 are fixedly installed at the four corners of the base plate 1 near the processor 6. A limiting groove 9 is opened at the end of the processor 6 near the back plate 17. The processor 6 is fixedly installed with the mounting frame 10 through the limiting groove 9. The advantage is that the snap-fit ​​structure between the limiting groove 9 and the mounting frame 10 allows the mounting frame 10 to be quickly disassembled without tools, which facilitates the replacement of the circuit board or electronic components inside the processor 6 and improves maintenance efficiency.

[0036] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, the end of the mounting frame 10 furthest from the processor 6 is threaded with a positioning bolt 12 that penetrates the mounting frame 10 and extends into its interior. The two ends of the back plate 17 furthest from the center line are fixedly installed with locking blocks 18 that are compatible with the slot 14. The advantage is that the cooperation between the locking blocks 18 and the slot 14 enables the quick installation of the back plate 17, forming rear protection for the processor 6. At the same time, together with the bottom plate 1, side plate 13, and top plate 20, they form a closed cavity to isolate external dust and moisture from corroding the internal circuitry.

[0038] Specifically, multiple heat dissipation fins 11 are fixedly installed at the end of the mounting frame 10 away from the processor 6, and multiple heat dissipation holes 19 with equal spacing are opened through one end of the back plate 17. The advantage is that the heat dissipation fins 11 are made of aluminum alloy, which accelerates heat conduction by increasing the surface area. Together with the heat dissipation holes 19 of the back plate 17, they form a "thermal convection channel" to avoid the calculation error of the force sensor 24 and the processor 6 caused by high temperature.

[0039] Specifically, one end of the top plate 20 is provided with a slide groove 23 that is adapted to the force sensor 24. The length of the slide groove 23 is half the length of the top plate 20. The advantage is that the slide groove 23 supports the force sensor 24 to slide freely within 50% of the length range of the top plate 20. The vertical position of the sensor can be adjusted according to the height of the pin clamp to adapt to test samples of different specifications.

[0040] Working Principle: During use, the groove 2 and side plate 13 form an "L-shaped" splicing structure, ensuring the vertical positioning of the base plate 1 and side plate 13, improving the overall rigidity of the equipment casing. The insertion and engagement of the limiting block 7 and slot 14 restricts the horizontal displacement of the processor 6, preventing the electrical connection between the processor 6 and side plate 13 from loosening due to vibration. It also provides lateral support for the processor 6, ensuring its stability during testing. The dimensions of slot 2 15 precisely match the electronic force value digital display 8, forming a rigid limiting structure to prevent the display from tilting or falling off due to external impact or equipment movement. The abutment design between the digital display 8 and side plate 13 disperses the impact load on the display. The snap-fit ​​structure between the limiting groove 9 and mounting frame 10 allows for quick disassembly and installation without tools. The frame 10 facilitates the replacement of circuit boards or electronic components inside the processor 6, improving maintenance efficiency. The cooperation between the card block 18 and the card slot 14 enables the quick installation of the back plate 17, forming rear protection for the processor 6. At the same time, together with the bottom plate 1, side plate 13, and top plate 20, it forms a closed cavity, isolating external dust and moisture from corroding the internal circuits. The heat dissipation fins 11 are made of aluminum alloy, which accelerates heat conduction by increasing the surface area. Together with the heat dissipation holes 19 of the back plate 17, they form a "thermal convection channel" to avoid calculation errors of the force sensor 24 and the processor 6 caused by high temperature. The slide 23 supports the force sensor 24 to slide freely within 50% of the length range of the top plate 20. The vertical position of the sensor can be adjusted according to the height of the pin clamp to adapt to test samples of different specifications.
