In the manufacturing process of electronic devices, whether it is consumer electronics such as mobile phones, tablets, and laptops, or electronic products in fields such as automotive electronics, industrial control, and medical electronics, probe testing is required to ensure the quality and reliability of products.

[0003] In the existing technology, during the printed circuit board manufacturing process, various types of probes are required to detect circuit connectivity, short circuits, open circuits, and other issues on the PCB board. During use, existing test fixtures are usually unable to fix probes of different sizes, reducing the versatility of the test fixture. Furthermore, when the fixture is worn and needs to be replaced, the entire test fixture needs to be disassembled, reducing work efficiency.

[0004] Therefore, a test fixture that facilitates the detection of different types of probes is proposed. Utility Model Content

The positive and negative thread screws are linked by the connecting rod. The rotation of the positive and negative thread screws drives the thread block and the placement plate to clamp inward. When the pull ring rod is released, the spring releases the stored energy and drives the pin rod to insert into the gear sleeve and lock. It can stably clamp probes of different sizes and adapt to various shapes, thereby achieving the effect of probe clamping.

[0016] (2) This utility model can replace V-shaped clamps of different sizes by setting a replacement and disassembly component, thereby increasing the range of fixation. By rotating the knob screw, under the action of the threaded hole and the threaded block, the knob screw rises and separates from the threaded block. Then, the rotating rod and connecting plate are rotated, and the V-shaped clamp and the threaded block can be taken out from the slot for maintenance and replacement. The rubber anti-slip pad is anti-slip and can also protect the probe surface. The V-shaped clamp can be disassembled and replaced in a short time without the need for complicated tools and tedious disassembly and installation operations, which greatly saves the preparation time when testing different types of probes, thereby achieving the effect of replacement and disassembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0026] Existing test fixtures typically cannot hold probes of different sizes, reducing the versatility of the test fixture. Furthermore, when the fixture wears out and needs replacement, the entire test fixture must be disassembled, reducing work efficiency. Therefore, this invention provides a preferred embodiment of a test fixture that facilitates the testing of different probe types. Figure 1-6As shown: A test fixture for facilitating the detection of different types of probes includes a base 1, the top of the base 1 is fixedly mounted on a bracket 2, a horizontal plate 3 is fixedly mounted between the inner walls of the bracket 2, a slide rod 4 is fixedly mounted at equal distances between the bottom of the horizontal plate 3 and the top of the base 1, a lifting plate 5 is slidably connected to the outer wall of the slide rod 4, a probe clamping assembly 6 is provided on the surface of the lifting plate 5, and a replacement and disassembly assembly 7 is provided on the surface of the probe clamping assembly 6.

[0027] The probe clamping assembly 6 specifically includes: a motor 611, fixedly installed on the top of the bracket 2; a screw 612, rotatably connected to the top of the horizontal plate 3; a connecting block 613, threadedly connected to the outer wall of the screw 612; a connecting frame 614, fixedly installed on one side of the connecting block 613; a cross groove 615, connected to the top of the horizontal plate 3; a knob connecting rod 6113, located on one side of the lifting plate 5; a gear sleeve 6114, fixedly sleeved on the outer wall of the knob connecting rod 6113; a top plate 6115, fixedly installed on the top side of the lifting plate 5; and a pull ring rod 6116, located on the top of the top plate 6115.

[0028] A rotating shaft is fixedly installed at the output end of the motor 611. The other end of the rotating shaft passes through the top of the bracket 2 and extends to the top of the inner wall of the bracket 2, where it is fixedly connected to the top of the screw 612. The bottom of the connecting frame 614 is fixedly connected to the top of the lifting plate 5.

[0029] A connecting rod 616 is fixedly installed between the inner walls of the cross groove 615. The outer wall of the connecting rod 616 is equidistantly and evenly connected to the slider 617. The outer wall of the slider 617 is slidably connected to the inner wall of the cross groove 615. The inner wall of the cross groove 615 is equidistantly and evenly provided with positive and negative threaded screws 618. The outer wall of the positive and negative threaded screws 618 is equidistantly threaded with threaded blocks 619. The outer wall of the threaded blocks 619 is slidably connected to the inner wall of the cross groove 615. A connecting rod 6111 is fixedly connected between the positive and negative threaded screws 618. A placement plate 6112 is fixedly installed between the inner side of the threaded block 619 and the inner side of the slider 617.

[0030] One end of the knob connecting rod 6113 moves through one side of the lifting plate 5 and extends into the interior of the cross groove 615, where it is fixedly connected to the other end of the positive and negative threaded rod 618. The outer wall of the knob connecting rod 6113 is rotatably connected to the inner wall of the lifting plate 5. The bottom of the pull ring rod 6116 moves through the top of the top plate 6115 and extends to the bottom of the top plate 6115. A nail rod 6117 is fixedly installed at the bottom of the pull ring rod 6116.

[0031] The bottom of the nail rod 6117 extends into the inner wall of the gear sleeve 6114 and engages with it. The outer wall of the pull ring rod 6116 is movably fitted with a spring 6118.

[0032] In this example, probes of different sizes can be fixed within a certain range by setting the probe clamping assembly 6. After the probe is placed between the clamps, the pull ring rod 6116 drives the nail rod 6117 to move upward. Then, the rotating knob connecting rod 6113 drives the positive and negative thread screws 618 to rotate. The positive and negative thread screws 618 are linked by the connecting rod 6111. The rotation of the positive and negative thread screws 618 drives the thread block 619 and the placement plate 6112 to clamp inward. When the pull ring rod 6116 is released, the spring 6118 releases its stored energy and drives the nail rod 6117 to insert into the gear sleeve 6114 and lock, thereby achieving the function of probe clamping. Example

[0033] Based on Embodiment 1, the present invention provides a preferred embodiment of a test fixture that facilitates the detection of different types of probes, for example... Figure 1-6 As shown: The replacement and disassembly assembly 7 specifically includes: a slot 711, which is formed on both sides of the inner wall of the placement plate 6112; a threaded block 712, which is slidably connected between the inner walls of the slot 711; a V-shaped clamp 713, which is fixedly installed between the inner sides of the threaded block 712; a rubber anti-slip pad 714, which is fixedly installed on the inner wall surface of the V-shaped clamp 713; and a rotating rod 715, which is equidistantly rotatably connected to the top of the placement plate 6112.

[0034] A connecting plate 716 is fixedly installed on the top of the rotating rod 715. A threaded hole is opened on the top of the connecting plate 716. A knob screw 717 is threadedly connected to the inner wall of the threaded hole. A compression sleeve 718 is fixedly sleeved on the outer wall of the knob screw 717. The bottom of the knob screw 717 extends to the internal threaded connection of the threaded block 712.

[0035] In this example, by setting up the replacement and disassembly assembly 7, different sizes of V-shaped clamps 713 can be replaced, increasing the fixing range. By rotating the knob screw 717, under the action of the threaded hole and the threaded locking block 712, the knob screw 717 rises and separates from the threaded locking block 712. Then, by rotating the rotating rod 715 and the connecting plate 716, the V-shaped clamp 713 and the threaded locking block 712 can be removed from the slot 711 for maintenance and replacement. The rubber anti-slip pad 714 provides anti-slip protection and also protects the probe surface, thereby achieving the purpose of replacement and disassembly.

[0036] Working principle: First, the probe is placed between the V-shaped clamps 713. The pull ring rod 6116 drives the nail rod 6117 to move upward, disengaging the nail rod 6117 from the limit of the gear sleeve 6114. Then, rotating the knob connecting rod 6113 drives the positive and negative threaded screws 618 to rotate. The positive and negative threaded screws 618 are linked by the connecting rod 6111. The rotation of the positive and negative threaded screws 618 drives the threaded block 619 and the placement plate 6112 to clamp inward. The slider 617 slides on the connecting rod 616. Then, the V-shaped groove in the V-shaped clamp 713 fixes the probe. The rubber anti-slip pad 714 provides anti-slip protection and protects the probe surface. After fixing, the pull ring rod 6116 is released, and the spring 6118 releases its stored energy to drive the nail rod 6117. 7. Insert the gear sleeve 6114 into the locking mechanism to ensure stability. When the V-shaped clamp 713 needs to be disassembled, maintained, or replaced, rotate the knob screw 717. Under the action of the threaded hole and the threaded locking block 712, the knob screw 717 rises and separates from the threaded locking block 712. Then, rotate the rotating rod 715 and the connecting plate 716 to rotate. The V-shaped clamp 713 and the threaded locking block 712 can then be removed from the slot 711 for maintenance and replacement. Starting the motor 611 can drive the screw 612 to rotate. The rotation of the screw 612 drives the connecting block 613, the connecting frame 614, and the lifting plate 5 to rise and fall, ultimately driving the fixed probe to perform detection, thereby achieving the function of probe clamping, replacement, and disassembly.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
