Description

Technical Field

[0001] This utility model relates to the field of test probe technology, specifically a PCB test probe holder reinforcement device. Background Technology

[0002] PCB test probes are key tools used for testing printed circuit boards, primarily for electrical performance testing, functional verification, or troubleshooting.

[0003] Some devices on the market typically install PCB test probes inside a mounting plate. By using a pressing device to control the mounting plate to slowly press down, the probes make vertical contact with the test points, avoiding lateral force that could cause the probe tips to deviate.

[0004] However, in actual use, when the test probe contacts the product for testing, the tip of the test probe is compressed, which impacts the connection between the test probe and the mounting base, making it prone to loosening. In view of this, we propose a PCB test probe holder reinforcement device. Utility Model Content

[0005] The purpose of this invention is to provide a PCB test probe holder reinforcement device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCB test probe holder reinforcement device, including a mounting base, a mounting hole on the upper surface of the mounting base, a test probe being snapped into the mounting hole, and a fixing component provided on the inner wall of the mounting hole, the fixing component including:

[0007] The mounting groove is formed on the inner wall of the mounting hole, and a spring is fixedly connected to the side of the inner wall of the mounting groove. A pressing element is fixedly connected to the end of the spring.

[0008] Preferably, the pressing member has a semi-circular protrusion on its side, and the protrusion is evenly distributed in a linear array on the side of the pressing member. The side of the pressing member near the mounting groove is rotatably connected to the inner wall of the mounting groove, which allows the pressing member to move inside the mounting groove.

[0009] Preferably, the size of the mounting slot is adapted to the size of the pressing member, and the two mounting slots are symmetrically arranged around the center of the mounting hole, which allows the two pressing members to more firmly limit the test probe.

[0010] Preferably, the center of the spring corresponds to the center of the mounting groove, and the size of the spring is adapted to the size of the mounting groove, allowing the spring to extend and retract inside the mounting groove.

[0011] Preferably, the outer surface of the test probe is provided with an auxiliary component, the auxiliary component including a right limiting member, the right limiting member being disposed on the outer surface of the test probe, a bolt being provided on the side of the right limiting member, a left limiting member being provided on the side of the right limiting member away from the bolt, and a protrusion being fixedly connected to the inner wall side of the left limiting member.

[0012] Preferably, the inner wall of the right limiting member is also fixedly connected with a protrusion, and the inner walls of the right limiting member and the left limiting member are in contact with the outer surface of the pressing member.

[0013] Preferably, the sides of the protrusions are arc-shaped, with two protrusions forming a group, and the two protrusions are symmetrically arranged around the center of the left limiting member.

[0014] Compared with the prior art, this utility model provides a PCB test probe holder reinforcement device, which has the following beneficial effects:

[0015] 1. This PCB test probe holder reinforcement device is designed to prevent the connection between the test probe and the mounting base from loosening when the test probe is under pressure. By pushing the top of the pressing component and bringing the end of the pressing component close to the inside of the mounting groove, the test probe is inserted into the mounting hole. At this point, the pressing component is released, and the spring force pushes the end of the pressing component toward the outer surface of the test probe. The protrusion on the side of the pressing component increases the friction between the pressing component and the test probe, thus ensuring that the test probe is firmly fixed in place.

[0016] 2. This PCB test probe holder reinforcement device, in order to make the test probe more securely installed, after the test probe is limited, the center of the left and right limiting parts are respectively aligned with the pressing parts, and then the left and right limiting parts are fitted together. At this time, a bolt is used to pass through the right and left limiting parts, so that the pressing parts can fit more tightly against the outer surface of the test probe, and the side of the protrusion contacts the outer surface of the test probe. This makes the test probe more securely installed. Attached Figure Description

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a PCB test probe holder reinforcement device, including a mounting base 1, a mounting hole 2 is provided on the upper surface of the mounting base 1, a test probe 3 is snapped into the mounting hole 2, and a fixing component 4 is provided on the inner wall of the mounting hole 2, the fixing component 4 including a mounting groove 401, a spring 402 and a pressing member 403.

[0023] In this embodiment of the present invention, the mounting groove 401 is formed on the inner wall of the mounting hole 2. The size of the mounting groove 401 is adapted to the size of the pressing member 403, and the two mounting grooves 401 are symmetrically arranged with respect to the center of the mounting hole 2. This allows the two pressing members 403 to more firmly limit the test probe 3. A spring 402 is fixedly connected to the side of the inner wall of the mounting groove 401. The center of the spring 402 corresponds to the center of the mounting groove 401. The size of the spring 402 is adapted to the size of the mounting groove 401, allowing the spring 402 to extend and retract inside the mounting groove 401. A pressing member 403 is fixedly connected to the end of the spring 402. A semi-circular protrusion is provided on the side of the pressing member 403, and the protrusion is evenly distributed in a linear array on the side of the pressing member 403. The side of the pressing member 403 near the mounting groove 401 is rotatably connected to the inner wall of the mounting groove 401, allowing the pressing member 403 to move inside the mounting groove 401.

[0024] Meanwhile, an auxiliary component 5 is provided on the outer surface of the test probe 3. The auxiliary component 5 includes a right limiting member 502, which is located on the outer surface of the test probe 3. A protrusion 503 is also fixedly connected to the inner wall of the right limiting member 502. The inner walls of the right limiting member 502 and the left limiting member 501 are in contact with the outer surface of the pressing member 403. A bolt 504 is provided on the side of the right limiting member 502. A left limiting member 501 is provided on the side of the right limiting member 502 away from the bolt 504. A protrusion 503 is fixedly connected to the inner wall of the left limiting member 501. The side of the protrusion 503 is arc-shaped, and two protrusions 503 are arc-shaped. The test probe 3 is arranged in a group, and the two protrusions 503 are symmetrically arranged at the center of the left limiting member 501. This allows the center of the left limiting member 501 and the right limiting member 502 to correspond to the pressing member 403 after the test probe 3 is limited. Then, the left limiting member 501 and the right limiting member 502 are put together. At this time, the bolt 504 is used to pass through the right limiting member 502 and the left limiting member 501, so that the pressing member 403 can fit more tightly against the outer surface of the test probe 3. At the same time, the side of the protrusion 503 contacts the outer surface of the test probe 3, so that the test probe 3 can be installed more firmly.

[0025] In this utility model, during use, push the top of the pressing member 403 so that the end of the pressing member 403 is close to the inside of the mounting groove 401, and then insert the test probe 3 into the mounting hole 2. At this time, release the pressing member 403, so that the elastic force of the spring 402 can push the end of the pressing member 403 toward the outer surface of the test probe 3. The protrusion provided on the side of the pressing member 403 can increase the friction between the pressing member 403 and the test probe 3, so that the test probe 3 can be firmly limited.

[0026] Furthermore, after the test probe 3 is positioned, the center of the left limiting member 501 and the right limiting member 502 are respectively aligned with the pressing member 403, and then the left limiting member 501 and the right limiting member 502 are brought together. At this time, the bolt 504 is passed through the right limiting member 502 and the left limiting member 501, so that the pressing member 403 can fit more tightly against the outer surface of the test probe 3, and at the same time, the side of the protrusion 503 contacts the outer surface of the test probe 3, so that the test probe 3 can be installed more firmly.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
