Description

Technical Field

[0001] This utility model relates to the field of protective shell technology, and more specifically, to semiconductor protective shells. Background Technology

[0002] In existing semiconductor protective enclosure technologies, the disassembly and installation of the cover are generally inconvenient, which severely restricts the maintenance efficiency and user experience of the equipment.

[0003] First, traditional semiconductor protective enclosures mostly use screws for fixing, requiring specialized tools for disassembly and assembly. This design requires operators to have various sizes of screwdrivers, and screws are prone to being lost or damaged during disassembly. Especially when there are many screws, the disassembly and assembly process is cumbersome and time-consuming, greatly reducing maintenance efficiency. This design is particularly inconvenient in emergency situations where rapid inspection or repair of chip circuit boards is needed, potentially leading to delays in troubleshooting and extended equipment downtime.

[0004] Secondly, many existing designs have complex connection structures between the cover and the bottom, lacking intuitiveness and standardization. Operators often need professional training to properly disassemble and assemble them. Novices are prone to deforming or damaging the snap-fit ​​parts due to improper operation. Although some protective shells use snap-fit ​​connection methods that eliminate screws, the snap-fit ​​strength is insufficient and they are prone to wear and failure due to frequent opening and closing, reducing product life and safety reliability.

[0005] Traditional protective casings typically employ a completely sealed design, prioritizing dust and water resistance while neglecting heat dissipation requirements. This design philosophy leads to internal heat buildup, which cannot be effectively dissipated, causing the chip's operating temperature to rise continuously. With the increasing power consumption of modern semiconductor chips, more and more heat is generated, and the heat dissipation bottleneck of the sealed structure becomes increasingly apparent, causing the chip to frequently throttle down or even shut down due to overheat protection.

The embedded groove is provided on the side wall of the snap-fit ​​rod. The counter-tension spring rod is slidably installed on the side wall of the snap-fit ​​tube. The rotating sleeve is rotatably limited and installed on the side wall of the snap-fit ​​tube. The pressing plate is installed on the rotating sleeve and can press against one end of the counter-tension spring rod.

[0011] The present invention is further configured such that mounting windows are symmetrically installed on the cover plate, and heat dissipation fans are installed on the mounting windows. The mounting windows and heat dissipation fans provide active heat dissipation while maintaining protective performance, effectively reducing the internal temperature and preventing electronic components from being damaged due to overheating.

[0012] The present invention is further configured such that a power supply cable groove is provided on the side of the protective shell, and the power supply cable groove provides a channel for the power supply cable of the chip circuit board.

[0013] The present invention is further configured such that the front end face of the protective shell is provided with a cable inlet / outlet groove, which provides a channel for the circuit of the chip circuit board. The power supply groove and the cable inlet / outlet groove provide a dedicated channel for the power supply lines and signal lines of the internal circuit board, so as to realize normal electrical connection in the closed state of the shell, while avoiding damage to the cables by compression.

[0014] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixedly installed on the bottom end face of the support plate. The connecting plate is located at the bottom of the side wall of the clamping tube, and is fixedly connected to the support plate to enhance the connection strength and prevent loosening during long-term use.

[0015] The present invention is further configured such that the locking rod is composed of two sections, and a bending spring is installed between the two sections of the locking rod. The bending spring in the middle provides a certain elastic adjustment capability, which can adapt to different usage angles and slight positional deviations, thereby enhancing the operational tolerance and ease of use.

[0016] The present invention is further configured such that a pressing block is installed at one end of the anti-tension spring rod, and the inner wall of the spinning plate presses against the pressing block, so that one end of the anti-tension spring rod extends into the embedded groove.

The snap-fit ​​rod 8 is mounted on the side ear plate 5 and can extend into the snap-fit ​​tube 7 to connect the side ear plate 5 and the support plate 6. The insert groove 9 is located on the side wall of the snap-fit ​​rod 8. The counter-tension spring rod 10 is slidably mounted on the side wall of the snap-fit ​​tube 7. The rotating sleeve 11 is mounted on the side wall of the snap-fit ​​tube 7 for limiting rotation. The spinning plate 12 is mounted on the rotating sleeve 11 and can press against one end of the counter-tension spring rod 10.

[0032] In this embodiment, the protective shell 2 serves as the bottom base, used to accommodate and fix the chip circuit board 1. The cover plate 4 is connected to the protective shell 2 via a hinge 3, allowing it to be flipped open and closed for easy operation and maintenance of the internal circuit board. When it needs to be closed, the cover plate 4 flips downwards to cover the protective shell 2, and the side lugs 5 on both sides align with the support plates 6 on both sides of the protective shell 2. At this time, the snap-fit ​​rods 8 on the side lugs 5 are aligned with the snap-fit ​​tubes 7 at the bottom of the support plates 6, preparing for subsequent locking operations. The power supply cable groove 18 and the inlet / outlet cable groove 19 designed on the protective shell 2 ensure that the power cable and signal cable can be connected normally in the closed state. The mounting window 17 and the cooling fan on the cover plate 4 ensure the heat dissipation requirements of the device in the working state. After the cover plate 4 is closed, the snap-fit ​​rods 8 on the side lugs 5... Rod 8 extends into the retaining tube 7 at the bottom of the support plate 6 for initial positioning. The retaining rod 8 has an embedding groove 9 on its side wall for engaging with the anti-tension spring rod 10 to form a lock. The rotating sleeve 11 is installed on the side wall of the retaining tube 7 and can limit rotation. When the rotating sleeve 11 is rotated, the spinning plate 12 on it presses against one end of the anti-tension spring rod 10 that is laterally slidably installed on the side wall of the retaining tube 7. After being pressured, the other end of the anti-tension spring rod 10 extends into the embedding groove 9 on the side wall of the retaining rod 8 to form a mechanical lock, firmly fixing the retaining rod 8 in the retaining tube 7, thereby locking the cover plate 4 and the protective shell 2. The retaining rod 8 adopts a two-section design with a bending spring 21 installed in the middle, which can adapt to different usage angles and slight positional deviations, enhancing the flexibility and reliability of the connection.

[0033] The clamping auxiliary mechanism includes a clamping ring 13, a double-layer collar 14, a bidirectional spring rod 15, and a mating hole 16. The clamping ring 13 is installed at the bottom end of the rotating sleeve 11. The double-layer collar 14 is fixedly installed on the outer wall of the clamping tube 7. The mating hole 16 is horizontally arranged on the double-layer collar 14 and is arranged in a ring on the double-layer collar 14.

[0034] In this embodiment, a clamping ring 13 is installed at the bottom end of the rotating sleeve 11, and a double-layer collar 14 is fixedly installed on the outer wall of the clamping tube 7. The double-layer collar 14 is provided with a ring of mating holes 16 arranged horizontally. The bidirectional spring rod 15 installed on the clamping ring 13 can cooperate with these mating holes 16. When the rotating sleeve 11 rotates, the bidirectional spring rod 15 on the clamping ring 13 will extend into the mating holes 16 on the double-layer collar 14 step by step, providing a clear positioning sense and a staged locking function, making the rotation process of the rotating sleeve 11 smooth and controllable, avoiding the problems of over-rotation or under-rotation, ensuring that the locking and clamping mechanism can be accurately positioned, and also preventing accidental loosening due to vibration or collision during use.

[0035] Please see Figures 1-5 As a supplementary embodiment of the semiconductor protective housing for the protection mechanism, locking mechanism and locking auxiliary mechanism: Installation windows 17 are symmetrically installed on the cover plate 4, and a heat dissipation fan is installed on the installation window 17. A power supply cable groove 18 is opened on the side of the protective housing 2, and the power supply cable groove 18 provides a channel for the power supply line of the chip circuit board 1. An inlet / outlet cable groove 19 is opened on the front end face of the protective housing 2, and the inlet / outlet cable groove 19 provides a channel for the circuit of the chip circuit board 1. A connecting plate 20 is installed at the bottom end of the side wall of the locking tube 7, and the connecting plate 20 is fixedly installed on the bottom end face of the support plate 6. The locking rod 8 is set in two sections, and a bending spring 21 is installed between the two sections of the locking rod 8. A pressing block 22 is installed at one end of the anti-tension spring rod 10, and the inner wall of the spinning plate 12 presses against the pressing block 22, so that one end of the anti-tension spring rod 10 extends into the embedded groove 9.

[0036] More specifically, the cover plate 4 is flipped down to cover the protective shell 2, so that the side ear plate 5 is aligned with the support plate 6, the locking rod 8 is aligned with the locking tube 7, and the locking rod 8 on the side ear plate 5 is inserted into the locking tube 7 at the bottom of the support plate 6 to complete the initial positioning and connection. The rotating sleeve 11 on the side wall of the locking tube 7 is rotated, and the spinning plate 12 presses against the pressing block 22 of the anti-tension spring rod 10, so that the other end of the anti-tension spring rod 10 extends into the embedding groove 9 on the side wall of the locking rod 8 to form a mechanical lock. During the rotation, the bidirectional spring rod 15 on the clamping ring 13 extends into the mating hole 16 of the double-layer collar 14 step by step to provide positioning feedback and stable support to ensure that the lock is in place. After locking, the cover plate 4 and the protective shell 2 form a closed space to protect the internal chip circuit board 1. The cooling fan operates through the mounting window 17 to ensure internal temperature control; the power supply and signal lines are connected to external devices through specially designed cable trays to ensure normal operation of the equipment. When it needs to be opened again, rotate the rotating sleeve 11 in the opposite direction to release the pressure of the rotating plate 12 on the anti-tension spring rod 10. The anti-tension spring rod 10 exits the embedded groove 9 under its own elastic force, releasing the locked state. Then the snap-fit ​​rod 8 can be pulled out and the cover plate 4 can be opened.

[0037] In summary, during the use or operation of the overall equipment: when the protective mechanism is required to operate, the protective shell 2 serves as the bottom base to accommodate and fix the chip circuit board 1. The cover plate 4 is connected to the protective shell 2 via the hinge 3 and can be flipped open and closed for easy operation and maintenance of the internal circuit board. When it needs to be closed, the cover plate 4 flips down to cover the protective shell 2, and the side ear plates 5 on both sides are aligned with the support plates 6 on both sides of the protective shell 2. At this time, the snap-fit ​​rods 8 on the side ear plates 5 are aligned with the snap-fit ​​tubes 7 at the bottom of the support plates 6 to prepare for subsequent locking operations. The power supply cable groove 18 and the inlet and outlet cable grooves 19 designed on the protective shell 2 ensure that the power cable and signal cable can be connected normally in the closed state. The mounting window 17 and the heat dissipation fan on the cover plate 4 ensure the heat dissipation requirements of the equipment in the working state.

[0038] When the locking mechanism needs to be operated, after the cover plate 4 is closed, the locking rod 8 on the side ear plate 5 extends into the locking tube 7 at the bottom of the support plate 6 to achieve initial positioning. The side wall of the locking rod 8 is provided with an embedding groove 9, which is used to cooperate with the anti-tension spring rod 10 to form a lock. The rotating sleeve 11 is installed on the side wall of the locking tube 7 and can limit rotation. When the rotating sleeve 11 is rotated, the spinning plate 12 on it will press against one end of the anti-tension spring rod 10 that is slidably installed on the side wall of the locking tube 7. After being pressured, the other end of the anti-tension spring rod 10 will extend into the embedding groove 9 on the side wall of the locking rod 8 to form a mechanical lock, which firmly fixes the locking rod 8 in the locking tube 7, thereby locking the cover plate 4 and the protective shell 2. The locking rod 8 adopts a two-section design with a bending spring 21 installed in the middle, which can adapt to different usage angles and slight position deviations, enhancing the flexibility and reliability of the connection.

[0039] When the locking auxiliary mechanism is in operation, a clamping ring 13 is installed at the bottom end of the rotating sleeve 11, and a double-layer collar 14 is fixedly installed on the outer wall of the locking tube 7. The double-layer collar 14 has a ring of mating holes 16 arranged horizontally. The bidirectional spring rod 15 installed on the clamping ring 13 can mate with these mating holes 16. When the rotating sleeve 11 rotates, the bidirectional spring rod 15 on the clamping ring 13 will extend into the mating holes 16 on the double-layer collar 14 step by step, providing a clear positioning sense and a staged locking function, making the rotation process of the rotating sleeve 11 smooth and controllable, avoiding the problems of over-rotation or under-rotation, ensuring that the locking mechanism can be accurately positioned, and also preventing accidental loosening due to vibration or collision during use.

[0040] Flip the cover plate 4 downwards to cover the protective shell 2, align the side ear plate 5 with the support plate 6, align the snap-fit ​​rod 8 with the snap-fit ​​tube 7, insert the snap-fit ​​rod 8 on the side ear plate 5 into the snap-fit ​​tube 7 at the bottom of the support plate 6 to complete the initial positioning and connection, rotate the rotating sleeve 11 on the side wall of the snap-fit ​​tube 7, and the spinning plate 12 presses against the pressing block 22 of the anti-tension spring rod 10, so that the other end of the anti-tension spring rod 10 extends into the embedding groove 9 on the side wall of the snap-fit ​​rod 8 to form a mechanical lock. During the rotation, the bidirectional spring rod 15 on the clamping ring 13 extends into the mating hole 16 of the double-layer collar 14 step by step to provide positioning feedback and stable support, ensuring that the lock is in place. After locking, the cover plate 4 and the protective shell 2 form a closed space to protect the internal chip circuit board 1. The cooling fan operates through the mounting window 17 to ensure internal temperature control; the power supply and signal lines are connected to external devices through specially designed cable trays to ensure normal operation of the equipment. When it needs to be opened again, rotate the rotating sleeve 11 in the opposite direction to release the pressure of the rotating plate 12 on the anti-tension spring rod 10. The anti-tension spring rod 10 exits the embedded groove 9 under its own elastic force, releasing the locked state. Then the snap-fit ​​rod 8 can be pulled out and the cover plate 4 can be opened.

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.
