[0002] In the sophisticated ecosystem of modern electronics manufacturing, PCB (printed circuit board) is the cornerstone of electronic components, and its quality directly affects the performance and reliability of end products. In order to ensure the accuracy of functions such as storage, signal processing and power distribution, it is essential to conduct rigorous electrical performance verification of assembled PCBs. This process traditionally relies on manually operated handheld test probes, which are simple in design and use dual-contact probes to manually contact preset test points on the PCB to verify the integrity of the circuit and electrical parameters, such as resistance and signal transmission quality, to judge whether the PCB meets the predetermined standards.

[0003] Despite this, traditional testing methods are facing severe challenges due to their inherent limitations. Given the increasing diversity of PCB designs on the market, fixed probe configurations are difficult to flexibly adapt to the unique test point layouts on various types of PCB boards. This not only requires manufacturers to customize probes for each new PCB design, but also leads to capital-intensive equipment investment, complex inventory management, and increased time costs due to frequent replacement and adjustment of probe configurations, which seriously restricts the response speed and overall efficiency of the production line. Therefore, the industry urgently needs an innovative manual probe pitch mechanism that can span across a variety of PCB design differences and provide a manual probe pitch mechanism with high versatility and adjustment accuracy, accelerate product verification cycles, and thereby promote production capacity upgrades and market competitiveness in the electronics manufacturing industry. In this context, the development of a manual probe pitch mechanism that is easy to adjust and has high adjustment accuracy has become the core demand of current technological innovation.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0036] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0037] In order to solve the problem that the distance between two probes in the manually operated handheld test probe in the prior art cannot be adjusted, the utility model provides a manual probe distance changing mechanism.

[0038] like Figure 1-6As shown, an embodiment of the utility model provides a probe manual distance changing mechanism, which includes: a first guide rail 1, a first mounting unit 2 and a second mounting unit 3, a first probe 4 and a second probe 5, and a transmission rod 6.

[0039] Specifically, the first guide rail 1 is extended along the first direction; the first mounting unit 2 and the second mounting unit 3 are arranged relatively to each other along the first direction and are arranged on the first guide rail 1; the first probe 4 is arranged on the first mounting unit 2, and the second probe 5 is arranged on the second mounting unit 3, and the needle heads of the first probe 4 and the second probe 5 are arranged at intervals in the first direction; in this way, in the first direction, there is a distance between the first probe 4 and the second probe 5 to adapt to two detection points on the PCB.

[0040] Furthermore, the transmission rod 6 is passed through the first mounting unit 2 and the second mounting unit 3 and can pivot relative to the two. The transmission rod 6 is threadedly connected to one of the two and can be driven to pivot relative to the mounting unit so that the mounting unit slides toward or away from the other mounting unit on the first guide rail 1.

[0041] It should be noted that the transmission rod 6 can be threadedly connected to the first mounting unit 2 or the second mounting unit 3. In this embodiment, the transmission rod 6 is threadedly connected to the first mounting unit 2. In this configuration, the principle of threaded transmission can be utilized. When the transmission rod 6 is driven to pivot relative to the first mounting unit 2, the first mounting unit 2 threadedly connected thereto can be driven to move toward or away from the second mounting unit 3 on the first guide rail 1, thereby achieving that the spacing between the needle head of the first probe 4 and the needle head of the second probe 5 in the first direction can be accurately adjusted.

[0042] It can be understood that in this embodiment, the first guide rail 1 can, on the one hand, guide the movement of the first mounting unit 2; on the other hand, it can also improve the adjustment precision when adjusting the distance between the two mounting units.

[0043] Preferably, when the transmission rod 6 is threadedly connected to the first mounting unit 2, the transmission rod 6 is also passed through the second mounting unit 3 and can pivot relative to the second mounting unit 3. When the transmission rod 6 pivots relative to the second mounting unit 3, the transmission rod 6 does not move relative to the second mounting unit 3 in the first direction. This arrangement can ensure that the first mounting unit 2 can move quickly toward or away from the second mounting unit 3 in the first direction.

[0044] In some embodiments, the transmission rod 6 may also be threadedly connected to the second mounting unit 3. When the transmission rod 6 is driven to pivot relative to the second mounting unit 3, the second mounting unit 3 threadedly connected thereto can be driven to move toward or away from the first mounting unit 2 on the first guide rail 1, thereby achieving that the spacing between the needle heads of the two probes in the first direction can be accurately adjusted.

[0045] Furthermore, when the transmission rod 6 is threadedly connected to the second mounting unit 3, the transmission rod 6 is also passed through the first mounting unit 2 and can pivot relative to the first mounting unit 2. When the transmission rod 6 pivots relative to the first mounting unit 2, the transmission rod 6 does not move relative to the first mounting unit 2 in the first direction. Such a configuration can ensure that the second mounting unit 3 can move quickly toward or away from the first mounting unit 2 in the first direction.

[0046] In the above arrangement, by utilizing the principle of threaded transmission, when the transmission rod 6 rotates, it can drive an installation unit threadedly connected thereto to move toward or away from another installation unit, thereby achieving that the spacing between the needle heads of the two probes in the first direction can be adjusted; and, the installation unit threadedly connected thereto is driven by the transmission rod 6 to slide on the first guide rail 1, thereby greatly improving the adjustment precision and stability during the adjustment process.

[0047] Preferably, the axial direction of the transmission rod 6 is arranged to be parallel to the first direction. Such an arrangement is conducive to the installation unit threadedly connected to the transmission rod 6 to convert the thread transmission into a linear motion in the first direction.

[0048] Furthermore, an external thread 61 is provided on the side wall of the transmission rod 6 near its first end along its circumference, and a threaded hole matching the external thread is provided on the first mounting unit 2 or the second mounting unit 3 .

[0049] Specifically in this embodiment, refer to Figure 2-4 As shown, the transmission rod 6 is set to be cylindrical, and in this embodiment, the threaded hole 211 is set on the first mounting unit 2. When the transmission rod 6 is driven to pivot, the transmission rod 6 is threadedly connected with the first mounting unit 2 through the external thread 61 thereon, and the first mounting unit 2 can slide on the first slide rail 1, that is, move along the first direction.

[0050] In the present invention, further, a groove structure 62 is provided at the end of the second end of the transmission rod.

[0051] Specifically in this embodiment, Figure 2As shown, the groove structure 62 is used to match with a screwdriver head so that the screwdriver head applies torque to the transmission rod 6 through the groove structure 62. Thus, the external thread 61 is matched with the threaded hole 211, and the transmission rod 6 and the first installation unit 2 are threadedly driven.

[0052] In the utility model, the transmission rod 6 also includes a limiting portion 63, and the limiting portion 63 is used to limit the position of the second mounting unit 3 or the first mounting unit 2 relative to the transmission rod 6 in the first direction, so that the first mounting unit 2 or the second mounting unit 3 can move toward or away from the second mounting unit 3 or the first mounting unit 2 on the first guide rail 1 when threadedly transmitted with the transmission rod 6.

[0053] Specifically, the limiting portion 63 is disposed on the side wall of the transmission rod 6 and is disposed close to the second end.

[0054] Specifically in this embodiment, Figure 3-4 As shown, the second end is passed through the second mounting unit 3, and the limiting portion 63 is used to limit the position of the second mounting unit 3 relative to the transmission rod 6 in the first direction, so that when the second mounting unit 3 pivots relative to the transmission rod 6, the second mounting unit 3 does not move relative to the transmission rod 6 in the first direction.

[0055] In the present invention, the limiting portion 63 is configured as a flange 64 formed along the circumference of the transmission rod, the flange 64 extends along the axial direction of the transmission rod 6 toward the second end, and the end surface of the flange 64 facing away from the first end is flush with the second end.

Thus, the distance between the needle head of the first probe 4 installed on the first mounting unit 2 and the needle head of the second probe 5 installed on the second mounting unit 3 in the first direction can be adjusted to practically use the detection points of PBAs of different specifications.

[0058] It should be noted that the groove structure 62 is located on the end surface of the second end of the transmission rod 6 and the end surface of the flange 64 facing away from the first end.
