Description

Technical Field

[0001] This invention relates to the field of connection equipment, and more particularly to a multi-layer board structure auxiliary installation anti-foolproof clamp. Background Technology

[0002] Electronic devices refer to devices composed of electronic components such as integrated circuits, transistors, and vacuum tubes, which utilize electronic technology (including software) to function. Typically, complex electronic devices require the integration of multi-layered board structures. These structures consist of multiple circuit boards connected via BTB connectors (board-to-board connectors). The BTB connectors sequentially engage with the circuit boards to achieve electrical connections between the multiple layers.

[0003] Taking a smartwatch as an example, the smartwatch has a double-layer circuit board installed inside its casing, with a gap between the two circuit boards. The upper circuit board is electrically connected to the smartwatch's display screen via a BTB connector. When assembling the smartwatch, the worker needs to snap the BTB connector on the display screen onto the upper circuit board.

[0004] Since the clamping force of BTB connectors is determined by the operator's experience, if the operator applies too much clamping pressure, it will cause the circuit board to deform and damage the local components on the circuit board, ultimately leading to malfunction of the smartwatch. Therefore, a new fixture needs to be developed to avoid deformation of the multi-layer board structure during assembly. Summary of the Invention

[0052] This embodiment provides a multi-layer board structure auxiliary installation error-proof fixture, applied to the installation of BTB connectors in multi-layer board structures. It assists workers in installing BTB connectors onto the upper circuit board of the multi-layer board structure. The multi-layer board structure is suitable for electronic devices such as smartwatches, smart glasses, and smart bracelets. Furthermore, by improving the structure of the multi-layer board structure auxiliary installation error-proof fixture, the multi-layer board structure will not deform due to excessive force when engaging with the BTB connector. The multi-layer board structure includes a first circuit board and a second circuit board, with the first circuit board positioned above the second circuit board and a gap forming between them. The first circuit board has a connection port, into which the BTB connector can engage.

[0053] like Figure 1As shown, the multilayer board structure auxiliary installation anti-foolproof fixture provided in this embodiment includes an installation station 10, a support block 20, a pushing component 30, and a locking component 40. The installation station 10 is used to place the multilayer board structure, which has a gap between the first and second circuit boards. The thickness of the support block 20 is not greater than the thickness of the gap, so that the support block 20 can extend into the gap. The pushing component 30 is fixedly connected to the support block 20 and is used to push the support block 20 into the gap along a first direction. The locking component 40 includes a first station and a second station arranged along the first direction. An anti-foolproof block 44 is provided at the first station, and a locking part is provided at the second station. When the pushing component 30 is located at the first station, the pushing component 30 is lifted by the anti-foolproof block 44, and the support block 20 is located above the first circuit board and covers the connection port. When the pushing component 30 is located at the second station, the pushing component 30 is locked by the locking part, and the support block 20 is located within the gap.

[0054] Specifically, when installing the BTB connector onto a multilayer board structure, the multilayer board structure is first placed on the installation station 10. Then, external force is applied to the pushing component 30, causing it to move from the first station to the second station. This pushes the support block 20 into the gap between the first and second circuit boards. Subsequently, the locking part secures the pushing component 30, keeping the support block 20 within the gap, thus supporting the upper first circuit board in the multilayer board structure. Next, the operator can then fasten the BTB connector to the upper first circuit board. During this process, because the upper first circuit board is supported by the support block 20, it prevents damage from the operator's force. Excessive clamping pressure is prevented to avoid stress exceeding the limit and to prevent damage or cracking of electronic components on the second circuit board in the multilayer board structure. At the same time, when the pushing component 30 is in the first station, the pushing component 30 is lifted by the anti-fooling block 44, that is, the support block 20 is lifted, so that the support block 20 can be positioned above the first circuit board and cover the connection port. At this time, it is inconvenient or impossible for the operator to perform BTB connector clamping. This prevents the operator from clamping the BTB connector on the upper first circuit board before the support block 20 is in place. It has an anti-fooling effect, avoids human operation errors, and further avoids structural deformation of the multilayer board during the BTB connector clamping process.

[0055] like Figures 1 to 3As shown, the pushing component 30 includes a mounting base 31, on which a force-bearing component 32 is slidably connected. The force-bearing component 32 can slide in a first direction, that is, it can slide in a direction close to or away from the mounting station 10. A support block 20 and a limiting block 33 are installed at the end of the force-bearing component 32 close to the mounting station 10. The limiting block 33 is used to be fixed by the locking component 40. It can be understood that when the worker needs to insert the support block 20 into the gap of the multilayer board structure, the worker can unlock the locking component 40 with one hand and push the force-bearing component 32 with the other hand, so that the limiting block 33 is in a position that can be locked by the locking component 40. Then, the worker releases both hands, and the locking component 40 locks the limiting block 33, and the support block 20 is already in the gap, playing a supporting role for the upper circuit board. Then, the worker can free up both hands to fasten the BTB connector to the upper circuit board. In this process, less manpower is used, which reduces labor costs and reduces the overall cost.

[0056] Furthermore, such as Figures 2 to 3 As shown, a slide rail assembly 34 is also installed on the mounting base 31, and the force-bearing component 32 is slidably connected to the mounting base 31 through the slide rail assembly 34; the force-bearing component 32 is provided with a positioning block 321 protruding outward, and a first magnet unit 351 is installed on the positioning block 321; the mounting base 31 is provided with a positioning groove 311 corresponding to the position of the positioning block 321, a second magnet unit 352 is installed on the groove wall of the positioning groove 311 near the installation position 10, and a third magnet unit 353 is installed on the groove wall of the positioning groove 311 away from the installation position 10; when the support block 20 is located within the gap, the first magnet unit 351 and the second magnet unit 352 are magnetically connected; when the support block 20 is not located within the gap, the first magnet unit 351 and the third magnet unit 353 are magnetically connected.

[0057] For example, when a worker needs to insert the support block 20 into the gap of the multilayer board structure, the worker can unlock the locking assembly 40 with one hand and push the force-receiving component 32 with the other. At this time, the first magnet unit 351 moves synchronously with the positioning block 321 of the force-receiving component 32, moving away from the third magnet unit 353. Simultaneously, the limiting block 33 is positioned in a position that can be locked by the locking assembly 40. Subsequently, the first magnet unit 351 and the second magnet unit 352 are magnetically connected. The worker releases both hands, and the locking assembly 40 locks the limiting block 33. The support block 20 is now located within the gap, providing support for the upper circuit board. The magnetic unit provides support; then, the operator can free up both hands to fasten the BTB connector onto the upper circuit board. During this process, the aforementioned magnetic unit assists in positioning the force-bearing component 32. At the same time, the magnetic feedback provides the operator with a prompt, indicating that the force-bearing component 32 has moved away from its initial position (when the first magnetic unit 351 moves away from the third magnetic unit 353) and that the force-bearing component 32 is in place and the support block 20 is within the gap (when the first magnetic unit 351 and the second magnetic unit 352 are magnetically connected). This further optimizes the user experience of the fixture and further prevents deformation of the multi-layer circuit board.

[0058] In this embodiment, as Figure 2 As shown, positioning blocks 321 protrude outward on both sides of the force-bearing component 32, and the slide rail assembly 34 is located between the two positioning blocks 321. Since positioning blocks 321 are provided on both sides of the force-bearing component 32, both sides are restricted by magnetic force, making the movement of the force-bearing component 32 more stable, ensuring the positional accuracy between the force-bearing component 32 and the slide rail assembly 34, and allowing the support block 20 to extend into the gap more accurately.

[0059] In this embodiment, as Figure 1 and Figure 2 As shown, the force-bearing component 32 has a connecting block 322 protruding along the direction close to the installation position 10; the support block 20 is installed on the side wall of the connecting block 322, and the limiting block 33 is installed on the top wall of the connecting block 322. It can be understood that this vertical layout makes the overall pushing component 30 more compact, and from the perspective of force, the limiting block 33 is fixed to the top of the connecting block 322 by the locking component 40. The lateral force exerted by the limiting block 33 on the connecting block 322 is a shear force, which reduces the deformation effect on the connecting block 322, thereby improving the positioning accuracy of the support block 20.

[0060] Furthermore, such as Figures 1 to 7As shown, the multi-layer board structure auxiliary installation anti-foolproof fixture also includes a sub-clamp 50 and a female clamp 60. The sub-clamp 50 is detachably installed on the female clamp 60. The female clamp 60 is provided with multiple positioning pins, and the sub-clamp 50 has pin holes corresponding to the positions of the positioning pins. By cooperating with the positioning pins through the pin holes, the sub-clamp 50 can be assembled onto the female clamp 60. At the same time, the pushing component 30 and the locking component 40 are both installed on the female clamp 60, and the sub-clamp 50 has an installation groove 51, in which the installation station 10 is located. Through the above arrangement, the multi-layer board structure can be assembled outside the female clamp 60 into the sub-clamp 50, which facilitates the installation of the multi-layer board structure by the operator and improves the installation accuracy. At the same time, the pushing component 30 and the locking component 40 on the female clamp 60 are pre-installed, which can ensure the installation accuracy between the support block 20 and the multi-layer board structure.

[0061] Furthermore, a rotating seat 70 is provided between the pushing component 30 and the female clamp 60; the pushing component 30 is mounted on the rotating seat 70; the rotating seat 70 is rotatably connected to the female clamp 60, and the rotating seat 70 can rotate in a direction approaching or away from the mounting station 10. It should be added that an adjustment groove is provided on the mounting base 31, through which fasteners such as screws can pass and connect to the rotating seat 70. Therefore, by adjusting the position of the adjustment groove relative to the rotating seat 70, the position of the mounting base 31 relative to the rotating seat 70 can be adjusted; more specifically, the initial position of the pushing component 30 can be adjusted, thereby controlling the movement space of the support block 20 and thus matching different types of multilayer board structures.

[0062] In this embodiment, as Figure 6 and Figure 7 As shown, the locking assembly 40 includes a locking base 41, and a locking part includes a snap-fit ​​part 42 protruding from the locking base 41. A locking groove 43 is formed between the snap-fit ​​part 42 and the locking base 41. A foolproof block 44 is disposed on one side of the locking groove 43. When the support block 20 is located in the gap, the end of the limiting block 33 is located in the locking groove 43 and between the foolproof block 44 and the snap-fit ​​part 42.

[0063] Furthermore, a trigger block 45 is movably connected to the locking base 41 on the side of the anti-fooling block 44 away from the locking part 42, and an initial groove 46 is formed between the anti-fooling block 44 and the trigger block 45; the trigger block 45 is connected to the anti-fooling block 44; an elastic unit is provided between the trigger block 45 and the locking base 41, one end of the elastic unit abuts against the trigger block 45, and the other end of the elastic unit abuts against the locking base 41. For example, when the worker rotates the rotating seat 70 in the direction close to the installation station 10, the limiting block 33 will fall into the initial groove 46. When the worker needs to insert the support block 20 into the gap of the multi-layer board structure, the worker can press the trigger block 45 with one hand to overcome the elastic force of the elastic unit. At this time, the worker pushes the force-bearing member 32 with the other hand to drive the limiting block 33 into the locking groove 43. Then, the worker releases both hands, the elastic unit resets, and the trigger block 45 and the anti-fool block 44 rise. At this time, the support block 20 is located in the gap, and the end of the limiting block 33 is located in the locking groove 43 and between the anti-fool block 44 and the snap-fit ​​part 42, which plays a role in fixing the support block 20.

[0064] In this embodiment, the distance between the locking groove 43 and the installation station 10 in the direction away from the installation station 10 is greater than the distance between the support block 20 and the installation station 10; the limiting block 33 includes an extension 331 extending in the direction away from the installation station 10 and a limiting part 332 for engaging in the locking groove 43. That is, the limiting block 33 is Z-shaped, making the overall structure more compact.

[0065] Next, to facilitate understanding by those skilled in the art, the principle of the support block 20 extending into the gap will be explained in conjunction with the accompanying drawings:

[0066] like Figure 4 As shown, in the initial state, the rotating seat 70 is positioned with its head facing upwards at 90°, and the sub-clamp 50 and the female clamp 60 are separated; then, as... Figure 5 As shown, the multi-layer board structure is placed into the mounting station 10 in the mounting groove 51, and the sub-clamp 50 is mounted onto the female clamp 60 using pins; then, as... Figure 6 As shown, when the rotating seat 70 is rotated in the direction close to the mounting slot 51, that is, close to the mounting station 10, the limiting block 33 will fall into the initial slot 46; at the same time, the pushing component 30 is positioned at the first station, and the foolproof block 44 lifts the limiting block 33, so that the support block 20 is positioned above the first circuit board to shield the connection port, thereby playing a foolproof role.

[0067] like Figure 1 and Figure 6As shown, the operator can press the trigger block 45 with one hand to overcome the elastic force of the elastic unit, causing the trigger block 45 and the anti-fooling block 44 to descend; at this time, the operator can push the force-bearing component 32 with the other hand, causing the limiting block 33 to enter the locking groove 43, that is, the pushing component 30 to be located in the second position; at the same time, the first magnet unit 351 moves synchronously with the positioning block 321 of the force-bearing component 32, moving away from the third magnet unit 353; after the support block 20 extends into the gap of the multilayer board structure, the limiting block 33 enters the locking groove 43 synchronously, and the first magnet unit 351 and the second magnet unit 352 are magnetically connected;

[0068] Then, the staff releases their hands, the elastic unit resets, causing the trigger block 45 and the anti-fool block 44 to rise. At this time, the support block 20 is located in the gap, and the end of the limit block 33 is located in the locking groove 43 and between the anti-fool block 44 and the snap-fit ​​part 42, which plays a role in fixing the support block 20.

[0069] At this point, the staff can fasten the BTB connector to the upper circuit board and ensure that the upper circuit board does not deform; after assembly, the above operation is reversed to remove the multilayer board structure.

[0070] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
