Description

Technical Field

[0001] This utility model relates to the field of locking mechanism technology, specifically a modular electronic component locking mechanism. Background Technology

[0002] Modular electronic components integrate multiple electronic components and their functions into a single modular unit. These modules typically have standard interfaces, allowing for easy connection and combination with other electronic devices or systems, much like building with blocks. Power supply modules are a type of modular electronic component. A power supply module can combine multiple components such as transformers, rectifiers, and filters, providing only input and output interfaces. This allows users to easily connect it to a circuit to obtain a stable power supply without needing to consider the complex internal circuit structure.

[0003] To ensure the normal operation of the power module, a heatsink is typically installed on it. The connection between the power module and the heatsink is usually achieved through screws or soldering. Screws make installation and removal cumbersome, requiring tools and time-consuming. Overtightening the screws can deform or damage the power module casing, while insufficient tightening can lead to poor contact between the heatsink and the power module, affecting heat dissipation. Soldering makes the heatsink and power module a single unit, making disassembly and replacement difficult. If one component malfunctions, both may need to be replaced, increasing repair costs and complexity. Therefore, a modular electronic component locking mechanism is designed to address these technical problems. Utility Model Content

[0030] In the installation of the cooling fins 20, the internal threaded positioning sleeve 40, the mounting rod 50, the pressing rod 60 and the reset connecting structure can quickly connect the cooling fins 20 and the positioning pin 30, so that the operation of installing and dismounting the cooling fins 20 is more convenient.

[0031] The connecting claw assembly includes a receiving hole 51 opened in the bottom side of the mounting rod 50, the inner wall of the receiving hole 51 is uniformly provided with a plurality of through grooves, the inner wall of each through groove is rotatably connected with a connecting plate 52, each connecting plate 52 is hingedly connected with a connecting rod 53, the top end of the plurality of connecting rods 53 is hingedly connected with the pressing rod 60.

[0032] In the fixing of the cooling fins 20, the mounting rod 50 passes through the inside of the positioning hole 31, and is in close contact with the positioning pin 30 through the plurality of connecting rods 53, the position of the pressing rod 60 and the mounting rod 50 is no longer moved through the plurality of connecting rods 53, and the mounting rod 50 is fixed.

[0033] It should be noted that the plurality of through grooves are uniformly distributed on the inner wall of the receiving hole 51, and the plurality of connecting plates 52 are inclinedly arranged, the length of the connecting plate 52 is less than the length of the through groove, so that the connecting plate 52 can be smoothly retracted into the inside of the through groove and the receiving hole 51, avoiding the connecting plate 52 exposed outside the mounting rod 50.

[0034] The reset assembly includes a mounting hole 54 opened in the inside of the mounting rod 50, the inner wall of the mounting hole 54 is connected with a spring 55, the end of the spring 55 is connected with a pressing movable block 56 connected with the pressing rod 60, the pressing movable block 56 is located in the inside of the mounting hole 54 and is in sliding connection with the mounting hole 54.

[0035] When fixing the mounting rod 50, the pressing rod 60 is moved downward, at this time, the extrusion movable block 56 is moved downward and extrudes the spring 55, and with the movement of the pressing rod 60, the connecting plate 52 will move and drive the connecting rod 53 to rotate, and with the rotation of the connecting rod 53, the connecting rod 53 is retracted into the through slot and the storage hole 51, so that the subsequent mounting rod 50 can smoothly pass through the inside of the positioning hole 31.

[0036] It should be noted that in the unused state, the extrusion movable block 56 closely fits the top end of the inner wall of the mounting hole 54, and the extrusion spring 55 does not produce elastic deformation, at this time, the connecting rod 53 is located outside the through slot.

[0039] The top side of the shell 10 is provided with a positioning hole two 12, and the internally threaded positioning sleeve 40 is inserted into the inside of the positioning hole two 12, and the outer diameter of the internally threaded positioning sleeve 40 is matched with the diameter of the positioning hole two 12.

[0040] The internally threaded positioning sleeve 40 and the positioning hole two 12 can quickly position the heat dissipation fin 20, so as to quickly fix the heat dissipation fin 20.

[0041] The outer surface of the mounting rod 50 is threadedly connected with a limiting pressing disc 70, the outer diameter of the limiting pressing disc 70 is greater than the outer diameter of the internally threaded positioning sleeve 40, and the limiting pressing disc 70 is lapped on the top end of the internally threaded positioning sleeve 40.

[0042] The limiting pressing disc 70 can avoid the internally threaded positioning sleeve 40 from continuing to move downward, and the limiting pressing disc 70 limits the operation of the internally threaded positioning sleeve 40, and the limiting pressing disc 70 facilitates the operator to press the pressing rod 60 downward.

[0043] The outer surface of the top end of the mounting rod 50 is threadedly connected with a protective end cover 57, a part of the pressing rod 60 is located in the inside of the protective end cover 57, and the outer diameter of the protective end cover 57 is smaller than the outer diameter of the limiting pressing disc 70.

[0044] The protective end cover 57 protects the pressing rod 60, avoids the operator from accidentally touching and pressing the pressing rod 60, and further ensures that the connecting rod 53 can stably fit with the positioning pin 30.

[0045] The side of the shell 10 adjacent to the positioning pin 30 is provided with a plurality of heat dissipation holes 13 for dissipating heat from the inside of the shell 10.

[0046] The working principle of installing the heat sink 20 is as follows:

[0047] 1) Insert the internally threaded positioning sleeve 40 into the positioning hole two 12, and make the heat sink 20 fit the top side of the shell 10;

[0048] 2) Insert the positioning pin 30 into the shell 10, and insert the positioning rod 32 into the positioning hole one 11, at this time the positioning hole 31 corresponds to the position of the internally threaded positioning sleeve 40;

[0049] 3) Move the pressing rod 60 downward, at this time the movable block 56 is moved downward and presses the spring 55, and with the movement of the pressing rod 60, the connecting plate 52 will move and drive the connecting rod 53 to rotate, and with the rotation of the connecting rod 53, the connecting rod 53 is retracted into the through slot and the receiving hole 51;

[0050] 4) Threadedly connect the mounting rod 50 with the internally threaded positioning sleeve 40 and move it downward, so that the mounting rod 50 is inserted into the positioning hole 31, and the connecting rod 53 is located below the positioning pin 30;

[0051] 5) Slowly loosen the pressing rod 60, and under the action of the spring 55, the connecting rod 53 is moved out of the through slot and is in an inclined state;

[0052] 6) Rotate the mounting rod 50 to move it upward, so that the connecting rod 53 tightly fits the positioning pin 30, thereby fixing the positioning pin 30;

[0053] 7) Rotate the limiting pressing disc 70 to move it downward, so that the limiting pressing disc 70 tightly fits the top end of the internally threaded positioning sleeve 40, thereby positioning the mounting rod 50, thereby completing the operation of installing the heat sink 20.

[0054] It should be noted that during the rotation of the mounting rod 50 to move it upward in step 6, when the connecting rod 53 tightly fits the positioning pin 30, the mounting rod 50 will be resisted, at this time the mounting rod 50 is not rotated any more, and at this time the heat sink 20 tightly fits the shell 10, avoiding the deformation of the shell 10 due to the large clamping force.
