Description

Technical Field

[0001] This utility model relates to the field of probe mounting technology, specifically a probe mounting fixture. Background Technology

[0002] Test probes are electronic components used in electronic testing to test PCBAs. Multiple probes need to be integrated and mounted on a probe block during use.

[0003] According to the "Probe Mounting Fixture" disclosed in Chinese Patent Publication No. CN207801132U, a tool for mounting a probe in the pinhole of a probe block is provided. The tool includes: a probe block limiting and fixing part for limiting and fixing the probe block; and a probe limiting and fixing part for limiting and fixing the probe, wherein the probe is movable along the probe extension direction on the probe limiting and fixing part; the pinhole of the probe block fixed on the probe block limiting and fixing part is aligned with the corresponding probe fixed on the probe limiting and fixing part.

[0004] The device installs the probe onto the probe block by setting up a probe block limiting and fixing part and a probe limiting and fixing part. However, during the installation process, the probe needs to be placed in the probe slot first. Since the probe slot is small, it is very inconvenient to install the probe and the installation efficiency is low. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a probe installation fixture. During the installation process, the probe is placed in the probe slot through a hopper. Since the cross-section of the hopper is a cone shape that is wider at the top and narrower at the bottom, it is very convenient to install the probe and the installation efficiency is high.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A probe mounting fixture includes a base with a fixing groove on the base. A probe block is placed in the fixing groove. A probe groove is provided on the base corresponding to the probe hole on the side of the probe block. The depth and width of the probe groove are not less than the diameter of the probe so that the probe groove can completely accommodate the probe. A plurality of probe grooves are arranged in parallel and spaced apart, and the upper ends of the plurality of probe grooves are sequentially arranged to correspond to the probe holes on the side of the probe block. A sliding groove is provided on the base at the lower end of the plurality of probe grooves, which is arranged along the arrangement direction of the probe grooves. A slider is slidably arranged in the sliding groove. A hopper is provided on the slider. The cross-section of the hopper is a cone shape that is wider at the top and narrower at the bottom, and the opening width of the bottom of the hopper is equal to the width of the probe groove.

[0007] Preferably, a receiving space is provided between the conical bottom of the hopper and the opening at the bottom of the hopper.

[0008] Preferably, the width of the tapered top of the hopper is 5 times the diameter of the probe, and the width of the accommodating space is equal to the width of the probe, so that the accommodating space can accommodate a single row of probes.

[0009] Preferably, the depth and width of the probe groove are equal to the diameter of the probe.

[0010] Preferably, a plurality of positioning slots are provided at intervals along the arrangement direction of the probe slots in the slide groove, the interval between adjacent positioning slots is equal to the interval between adjacent probe slots, and a positioning block is provided on the slider corresponding to the positioning slot.

[0011] Preferably, the positioning block is slidably disposed on the slider, the lower end of the positioning block is hemispherical, and the diameter of the hemispherical shape is greater than the width of the positioning groove, and a spring is provided at the upper end of the positioning block.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: In use, the probe is inserted from the top of the hopper. Because the hopper has a tapered cross-section that is wider at the top and narrower at the bottom, the probe is corrected by the tapered slope and falls to the bottom of the hopper. By pushing the slider to slide in the groove, the hopper is moved towards the probe slot. After the opening at the bottom of the hopper coincides with the probe slot, the probe falls into the probe slot. The hopper is moved again until its bottom opening coincides with the next probe slot, and the probe is inserted into the hopper again. During installation, the probe is placed in the probe slot through the hopper. Because the hopper has a tapered cross-section that is wider at the top and narrower at the bottom, it is very convenient to insert the probe and the installation efficiency is high.

[0015] 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. 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.

[0016] This utility model provides the following technical solution: Combination Figure 1 and Figure 2 As shown, this embodiment discloses a probe mounting fixture, including a base 1, a fixing groove 2 on the base 1, a probe block 3 placed in the fixing groove 2, and a probe groove 4 on the base 1 corresponding to the probe hole on the side of the probe block 3. The depth and width of the probe groove 4 are not less than the diameter of the probe so that the probe groove 4 can completely accommodate the probe. A plurality of probe grooves 4 are arranged in parallel at intervals, and the upper ends of the plurality of probe grooves 4 are sequentially arranged to correspond to the probe holes on the side of the probe block 3. A sliding groove 5 is provided on the base 1 at the lower end of the plurality of probe grooves 4 along the arrangement direction of the probe grooves 4. A slider 6 is slidably arranged in the sliding groove 5. A hopper 7 is provided on the slider 6. The cross-section of the hopper 7 is a cone shape that is wider at the top and narrower at the bottom, and the opening width of the bottom of the hopper 7 is equal to the width of the probe groove 4.

[0017] In use, the probe is inserted from the top of the hopper 7. Because the hopper 7 has a tapered cross-section that is wider at the top and narrower at the bottom, the probe is corrected in direction by the tapered slope and falls to the bottom of the hopper 7, making the probe at the bottom parallel to the probe slot 4. The opening at the bottom of the hopper 7 rests against the surface of the base 1 to prevent the probe from leaking out. By pushing the slider 6 to slide within the groove 5, the hopper 7 moves towards the probe slot 4. After the opening at the bottom of the hopper 7 coincides with the probe slot 4, the probe falls into the probe slot 4. Due to the depth and width of the probe slot 4... All probe slots 4 are not smaller than the diameter of the probe, so that the probe slots 4 can fully accommodate the probe. Move the hopper 7 again until its bottom opening coincides with the next probe slot 4, and put the probe into the hopper 7 again. Repeat the operation until all probe slots 4 are filled with probes. Then tilt the base 1 so that the probes in the probe slots 4 slide into the probe holes on the side of the probe block 3 to complete the installation of the probes. During the installation process, the probes are placed in the probe slots 4 through the hopper 7. Since the cross-section of the hopper 7 is a cone shape that is wider at the top and narrower at the bottom, it is very convenient to install the probes and the installation efficiency is high.

[0018] Specifically, in combination Figure 3 As shown, a receiving space 8 is provided between the conical bottom of the hopper 7 and the opening at the bottom of the hopper 7.

[0019] The accommodating space 8 allows multiple probes to be stored in the hopper 7, eliminating the need to load probes after each movement of the hopper 7, further facilitating the operation of loading probes into the probe slot 4.

[0020] Specifically, in combination Figure 3 As shown, the width of the conical top of the hopper 7 is 5 times the diameter of the probe, and the width of the accommodating space 8 is equal to the width of the probe, so that the accommodating space 8 can accommodate a single row of probes.

[0021] The width of the conical top of the hopper 7 is 5 times the diameter of the probe and less than the length of the probe. This allows the tilted probe to be corrected by the conical slope when it is put into the hopper 7, eliminating the need for fine operation and reducing fatigue. At the same time, the width of the accommodating space 8 is equal to the width of the probe and the opening width at the bottom of the hopper 7, so that the accommodating space 8 can accommodate a single row of probes and prevent the probes from blocking the opening at the bottom of the hopper 7.

[0022] Specifically, in combination Figure 3 As shown, the depth and width of the probe groove 4 are both equal to the diameter of the probe.

[0023] This ensures that the probe slot 4 can fully accommodate the probe, preventing the top of the probe from protruding and affecting the movement of the hopper 7.

[0024] Specifically, in combination Figure 4 As shown, a plurality of positioning grooves 9 are arranged at intervals along the arrangement direction of the probe grooves 4 in the slide groove 5. The interval between adjacent positioning grooves 9 is equal to the interval between adjacent probe grooves 4. Positioning blocks 10 are arranged on the slider 6 corresponding to the positioning grooves 9.

[0025] The positioning groove 9 and the positioning block 10 are configured such that when the positioning block 10 is embedded in the positioning groove 9, the opening at the bottom of the hopper 7 coincides with the probe groove 4, which makes it easy for the probe to fall accurately into the probe groove 4.

[0026] Specifically, the positioning block 10 is slidably disposed on the slider 6, the lower end of the positioning block 10 is hemispherical, and the diameter of the hemispherical shape is greater than the width of the positioning groove 9, and a spring 11 is provided at the upper end of the positioning block 10.

[0027] When the positioning block 10 is embedded in the positioning groove 9, the spring 11 pushes the positioning block 10 into the positioning groove 9, which makes the positioning position clear and generates vibration, making it easier for the probe to fall into the probe groove 4.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
