[0017] Example

[0018] like Figure 1-3As shown, the present invention proposes a claw spring probe test holder, including a base 1, a claw spring probe 2 disposed within the base 1, and two sets of mounting slots 6 formed on the base 1. The claw spring probe 2 is installed correspondingly to the mounting slots 6. The claw spring probe 2 includes two sets of mounting plates 21, the mounting ends of which are installed correspondingly to the inner walls of the mounting slots 6 and are fixedly connected. Multiple sets of probe assemblies 22 are disposed above each set of mounting plates 21, and each set of probe assemblies 22 includes a needle tube 221, the mounting end of which is connected to the inner wall of the mounting slot 6. The needle tube 221 is fixedly connected to the mounting plate 21 and is installed on the upper side of the mounting plate 21. A needle body 222 is disposed inside the needle tube 221, which is hollow. The outer ring of the mounting end of the needle body 222 is in contact with the inner wall of the needle tube 221. The needle body 222 and the needle tube 221 are slidably connected. When the needle body 222 and the needle tube 221 are in the assembled state, the needle tube 221 guides and limits the movement of the needle body 222. A needle tip 223 is disposed at the top of the needle body 222. The top of the needle tip 223 is elastically claw-shaped. The addition of the needle tip 223 increases... To ensure contact area and stability with the component under test, the mounting end of the needle tip 223 is installed correspondingly to the top end of the needle body 222. The mounting end of the needle tip 223 is threadedly connected to the top end of the needle body 222. This threaded connection between the needle tip 223 and the needle body 222 facilitates subsequent individual replacement and maintenance of the needle tip 223 by the operator, greatly reducing workpiece wear and improving product utilization. A spring 224 is installed between the mounting end of the needle body 222 and the inner cavity of the needle tube 221. The two ends of the spring 224 are respectively connected to the needle body 222 and the needle tube 221. The inner cavity of the needle tube 221 is correspondingly installed. One end of the spring 224 is fixedly connected to the bottom of the inner wall of the needle tube 221, and the other end of the spring 224 is fixedly connected to the bottom side of the needle body 222. The spring 224 can push the needle body 222, so that the needle body 222 can drive the needle tip 223 to always keep it in a vertical state, thereby ensuring stable contact between the needle tip 223 and the tested element. The claw spring probe 2 has good electrical conductivity and contact stability, which can ensure that the signal transmission is not interfered with during the test and reduce the occurrence of errors.

[0019] A stabilizing plate 3 is provided above the base 1. An assembly groove 7 is provided on the base 1. The mounting end of the stabilizing plate 3 is installed correspondingly to the assembly groove 7. The mounting end of the stabilizing plate 3 is fixed to the inner wall of the assembly groove 7 by bolts. Multiple sets of positioning holes 8 are provided on the stabilizing plate 3. The top end of the needle tube 221 is installed correspondingly to the lower side of the stabilizing plate 3. The setting of the stabilizing plate 3 can further improve the stability of the probe assembly 22 when it is in the assembled state. The outer ring of the needle body 222 fits against the inner wall of the positioning hole 8. The needle body 222 is slidably connected to the positioning hole 8. Multiple sets of positioning holes 8 are adapted to the needle body 222. The setting of the positioning hole 8 can vertically guide the needle body 222, so that the needle tip 223 can make stable contact with the detection point of the tested element.

[0020] A positioning plate 4 is provided above the stabilizing plate 3. The mounting end of the positioning plate 4 is in contact with the upper side of the stabilizing plate 3. A positioning groove 9 is provided on the upper part of the positioning plate 4. The positioning groove 9 is adapted to the component to be tested. The positioning groove 9 can stably place the component to be tested, thereby ensuring the accuracy of the test data. Multiple sets of pin slots 10 are provided on the positioning plate 4. The multiple sets of pin slots 10 are adapted to the test pins of the component to be tested. The positioning plate 4 can be replaced according to different specifications of the component to be tested. The positioning plate 4 can be adapted to the stable test operation of different components to be tested, which greatly improves the versatility and utilization of this product.

[0021] Both sides of the stabilizing plate 3 are provided with snap-fit ​​components 5. The snap-fit ​​components 5 include a mounting base 51 and a snap plate 52. The mounting end of the mounting base 51 is installed correspondingly to the stabilizing plate 3 and is fixedly connected to the stabilizing plate 3. The mounting end of the snap plate 52 is installed correspondingly to the mounting base 51 and is rotatably connected to the mounting base 51. A locking block 53 is provided on one side of the snap plate 52, and the mounting end of the locking block 53 is fixedly connected to the snap plate 52. Both sides of the positioning plate 4 are provided with locking slots 11. The locking blocks 53 are installed correspondingly to the locking slots 11 and are interlocked. When the snap-fit ​​components 5 are in the closed state, the snap-fit ​​components are locked. Block 53 and slot 11 interlock, making the positioning plate 4 more stable when placed above the stabilizing plate 3. At this time, the bottom of the positioning plate 4 presses the needle 223, and the needle body 222 drives the needle 223 to retract. The spring 224 is in a compressed state. The needle 223 located at the pin slot 10 on the positioning plate 4 can make contact with the pins of the component to be tested placed in the positioning slot 9 under the action of the spring 224. The setting of the snap-fit ​​assembly 5 makes it easy for the operator to quickly replace different positioning plates 4 according to the component to be tested, making the operation convenient and quick and improving the work efficiency.

[0022] In this embodiment, the operator first assembles the positioning plate 4, which is compatible with the component to be tested, on top of the stabilizing plate 3. Then, the operator moves the buckle plate 52 to one side, so that the buckle plate 52 and the slot 11 on the positioning plate 4 are mutually engaged. At this time, the bottom side of the positioning plate 4 presses the needle 223, causing the needle body 222 to drive the needle 223 to retract, and the spring 224 is compressed. At the same time, the needle 223 located at the pin slot 10 on the positioning plate 4 is positioned in the pin slot 10 under the action of the spring 224. Then, the operator places the component to be tested stably in the positioning slot 9. At this time, the pins of the component to be tested correspond to the pin slot 10, so that the top of the needle 223 contacts the pin of the component to be tested. At this time, the needle 223 buffers the contact with the pin of the component to be tested under its own elasticity, reducing the wear between the needle 223 and the pin, and thus the testing operation of the component to be tested begins.

[0023] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
