Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more specifically, to a multi-chip module integrated circuit board. Background Technology

[0002] Circuit boards are an important component of electronic devices. As the demand for different electronic devices increases, a large number of electronic components need to be placed on the circuit boards. In order to facilitate the disassembly and replacement of various functional electronic components, circuit boards are modularly combined to form integrated circuits, thereby facilitating the disassembly and replacement of different electronic components and avoiding the inconvenience caused by soldering and other operations.

[0003] In common modular integrated circuit boards, modules are usually fixed together with bolts to form a large integrated circuit board. However, bolt fixing is inconvenient. Disassembly requires workers to use tools to tighten each bolt individually, which is labor-intensive and inefficient. Frequent bolt removal and installation can also damage the circuit board. Furthermore, when the electronic board is working, the electronic components are affected by external electromagnetic devices. Modular integrated circuits generally lack shielding structures, which cannot provide protection and can easily affect the cooperation of electronic components, impacting the working quality of the circuit. In addition, electronic components generate heat during operation, and a large number of modules together generate even more heat. Over time, this can raise the ambient temperature, and excessively high circuit board temperatures can affect the efficiency of the equipment and, in severe cases, cause circuit damage.

[0030] Please see Figure 1-5 A multi-chip module integrated circuit board includes a board body 1. A sliding block 2 is provided at one vertical end of the board body 1, and a sliding groove 3 is provided at the other end. The sliding block 2 and the sliding groove 3 are slidably engaged. A first limiting block 4 is slidably connected on the sliding block 2. A first limiting groove 5 is provided in the sliding groove 3. The first limiting block 4 and the first limiting groove 5 are engaged. An insertion block 6 is provided at one horizontal end of the board body 1, and an insertion groove 7 is provided at the other end. The insertion block 6 and the insertion groove 7 are engaged. A second limiting block 8 is slidably connected on the insertion block 6. A second limiting groove 9 is provided in the insertion groove 7. The second limiting block 8 and the second limiting groove 9 are engaged.

[0031] The plate 1 is provided with a protective cover 10, the inner side of the protective cover 10 is provided with a shielding layer 11, the lower end of the protective cover 10 is provided with a fixing member 12, and the plate 1 is provided with a fixing hole 13, which is matched with the fixing member 12.

[0032] In this embodiment, the plate 1 provides a structure for mounting and soldering component modules such as chips. When assembling multiple modules of the plate 1, if vertical assembly is performed, the sliding block 2 on the adjacent plate 1 is slid into the sliding groove 3 of another plate 1, and then the first limiting block 4 is inserted into the first limiting groove 5 to form a limiting structure, thereby fixing the vertically adjacent plates 1 together. If horizontal assembly is performed, the insertion block 6 on the adjacent plate 1 is inserted into the insertion groove 7 of another plate 1, and then the second limiting block 8 is inserted into the second limiting groove 9 to form a limiting structure, thereby fixing the horizontally adjacent plates 1 together.

[0033] More specifically, when the dust collection circuit board is working, the protective cover 10 provides a protective structure, the fixing member 12 is inserted into the corresponding fixing hole 13, and the protective cover 10 is fixed on the board body 1, covering the circuit components on the board body 1 and providing protection. In addition, the internal shielding layer 11 provides the ability to isolate electromagnetic fields and avoid the influence of external electromagnetic fields.

[0034] Please see Figure 5 As one method of heat dissipation during operation: a ventilation cavity 14 is provided on the protective cover 10, a small fan 15 is provided in the ventilation cavity 14, a heat dissipation fin 16 is provided in the ventilation cavity 14, a heat conduction rod 17 is provided at the lower end of the heat dissipation fin 16, a heat conduction plate 18 is provided on the inner side of the protective cover 10, and the heat conduction rod 17 passes through the protective cover 10 and cooperates with the heat conduction plate 18.

[0035] Specifically, the heat is absorbed by the heat-conducting plate 18 and then transferred to the heat dissipation fins 16 through the heat-conducting rod 17. The fan guides the external airflow through the ventilation cavity 14, so that it comes into contact with the heat dissipation fins 16 to exchange heat and carry the heat away from the equipment, thus providing heat dissipation capacity.

[0036] Please see Figure 1 As a further implementation of the ventilation cavity: dustproof nets 19 are provided at both ends of the ventilation cavity 14.

[0037] Specifically, the dustproof net 19 is used to protect both ends of the ventilation cavity 14 from dust to prevent external dust from entering and affecting the heat dissipation effect.

[0038] Please see Figure 3 As a further implementation of the limiting block: both the sliding block 2 and the insertion block 6 are provided with a shrinkage groove 20, and a thrust spring 21 is provided in the shrinkage groove 20. The lower ends of the first limiting block 4 and the second limiting block 8 are provided with limiting sliders 22, and the limiting sliders 22 slide in cooperation with the shrinkage groove 20.

[0039] Specifically, the shrinkage groove 20 provides space and cooperates with the limiting slider 22 to allow the corresponding first limiting block 4 and second limiting block 8 to slide stably on their respective structures. The thrust spring 21 keeps the first limiting block 4 and second limiting block 8 under an upward force, so that the limiting fixation remains stable.

[0040] Please see Figure 3 As a further implementation of the limiting block: the first limiting block 4 is provided with a first arc-shaped head 23 at one end, the second limiting block 8 is provided with a second arc-shaped head 24 at one end, and the first arc-shaped head 23 is located at the outer end of the first limiting block 4.

[0041] Specifically, when the sliding block 2 is inserted into the sliding groove 3, the first arc-shaped head 23 will contact the upper part of the sliding groove 3 before the first limiting block 4, thereby moving downward and retracting into the corresponding shrinkage groove 20, so as to facilitate entering the sliding groove 3 and cooperating with the second limiting block 8. The first arc-shaped head 23, which is set outward, allows the sliding block 2 to be freely inserted into the sliding groove 3 from both the top and bottom directions. When the insertion block 6 enters the insertion groove 7, the second arc-shaped head 24 will contact the upper part of the insertion groove 7 before the second limiting block 8, thereby moving downward and retracting into the shrinkage groove 20, stably entering the insertion groove 7 and cooperating with the second limiting groove 9.

[0042] Please see Figure 3 As a further implementation of the first limiting block: a connecting groove 25 is provided in the sliding block 2, and a connecting rod 26 is provided in the connecting groove 25. The two ends of the connecting rod 26 are connected to the limiting slider 22 of the first limiting block 4.

[0043] Specifically, the connecting groove 25 provides space for the linkage rod 26 to move. When the first limiting block 4 on one side moves downward due to pressure, the linkage rod 26 will drive the first limiting block 4 on the other end to descend together, avoiding interference with the outer wall of the sliding groove 3 and facilitating the insertion.

[0044] Please see Figure 2-4 As a further implementation of the limiting groove: both the first limiting groove 5 and the second limiting groove 9 are provided with a pressure block 27, the upper end of the pressure block 27 is provided with a transmission column 28, the transmission column 28 cooperates with the plate 1, and the upper end of the transmission column 28 is provided with a pressure plate 29.

[0045] Specifically, when the first limiting block 4 and the second limiting block 8 are inserted into the first limiting groove 5 and the second limiting groove 9 respectively, the first limiting block 4 and the second limiting block 8 will contact the corresponding pressure plate and push the pressure plate to move, thereby facilitating their own extension. When it is necessary to disassemble the plate 1, by pressing the corresponding pressure plate 29, under the transmission of the transmission column 28, the pressure block 27 will press the corresponding first limiting block 4 or second limiting block 8 into the shrinkage groove 20.

[0046] Please see Figure 4 and Figure 5 As a further embodiment of the fastener: the fastener 12 has an inwardly narrowed opening 30 in the middle, a limiting head 31 on the outer side of the fastener 12, and a fixing groove 32 at the lower end of the fixing hole 13, which cooperates with the limiting head 31.

[0047] Specifically, the recessed opening 30 provides space, allowing the two sides of the fixing member 12 to move inward. This moves the limiting head 31 towards the center, facilitating its passage through the fixing hole 13. The fixing member 12 then resets itself due to its own resilience and cooperates with the fixing groove 32 to provide fixation.

[0048] In summary, during the use or operation of the entire device:

[0049] When using the equipment, multiple boards 1 are combined according to requirements to meet the needs of multi-chip module integrated circuits. For vertical assembly, the sliding block 2 on adjacent boards 1 is slid into the sliding groove 3 of another board 1, and then, under the action of the thrust spring 21, the first limiting block 4 is inserted into the first limiting groove 5 to form a limiting structure, thus fixing the vertically adjacent boards 1 together. For horizontal assembly, the insertion block 6 on adjacent boards 1 is inserted into the insertion groove 7 of another board 1, and then, under the action of the thrust spring 21, the first limiting block 4 is inserted into the first limiting groove 5 to form a limiting structure, thus fixing the vertically adjacent boards 1 together. Under the action of 21, the second limiting block 8 is inserted into the second limiting groove 9, forming a limiting structure, thereby fixing and combining the horizontally adjacent plates 1. In addition, the shrinkage groove 20 provides space to cooperate with the limiting slider 22, so that the corresponding first limiting block 4 and second limiting block 8 can slide stably on their respective structures. Moreover, when the sliding block 2 is inserted into the sliding groove 3, the first arc-shaped head 23 will contact the upper part of the sliding groove 3 before the first limiting block 4, thereby moving downward and retracting into the corresponding shrinkage groove 20, which facilitates entry into the sliding groove 3 and the second limiting block 9. The first arc-shaped head 23, which is positioned outwardly, allows the sliding block 2 to be freely inserted into the sliding groove 3 from both vertical and horizontal directions. The connecting groove 25 provides space, allowing the linkage rod 26 to move. When the first limiting block 4 on one side moves downward due to pressure, the linkage rod 26 causes the first limiting block 4 on the other end to descend as well, preventing interference with the outer wall of the sliding groove 3 and facilitating insertion. When the insertion block 6 enters the insertion groove 7, the second arc-shaped head 24 contacts the upper part of the insertion groove 7 before the second limiting block 8. The downward movement retracts into the shrinkage groove 20, facilitating entry into the insertion groove 7 and engagement with the second limiting groove 9. Additionally, when the first limiting block 4 and the second limiting block 8 are respectively inserted into the first limiting groove 5 and the second limiting groove 9, the first limiting block 4 and the second limiting block 8 will contact the corresponding pressure plate, pushing the pressure plate to move, thus facilitating their own extension. When it is necessary to disassemble the plate 1, by pressing the corresponding pressure plate 29, under the transmission of the transmission column 28, the pressure block 27 presses the corresponding first limiting block 4 or second limiting block 8 into the shrinkage groove 20.

[0050] When the dust collection circuit board is working, the protective cover 10 provides a protective structure, and the inward opening 30 provides space, allowing the two sides of the fixing member 12 to move inward. This moves the limiting head 31 towards the center, inserting the fixing member 12 into the corresponding fixing hole 13, allowing the limiting head 31 to pass through the fixing hole 13. Under the inherent toughness of the fixing member 12, it resets and then cooperates with the fixing groove 32 to provide fixation, fixing the protective cover 10 to the board body 1, covering the circuit components on the board body 1, providing protection. The internal shielding layer 11 provides electromagnetic isolation, avoiding the influence of external electromagnetic fields. The heat-conducting plate 18 absorbs the heat emitted from the body and then transfers it to the heat dissipation fins 16 through the heat-conducting rod 17. The operation of the fan guides the external airflow through the ventilation cavity 14, thereby contacting the heat dissipation fins 16 for heat exchange, carrying the heat away from the equipment, providing heat dissipation. In addition, the dustproof net 19 protects the two ends of the ventilation cavity 14 from dust, preventing external dust from entering and affecting the heat dissipation effect.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
