Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microcomputer protection devices, and particularly relates to a clamping assembly and a microcomputer protection device for power systems. BACKGROUND

[0002] The microcomputer protection device is composed of high-integration bus-out-chip single-chip microcomputer, high-precision current and voltage transformers, high-insulation-strength outlet intermediate relay, high-reliability switching power supply module and other components. At present, the CPU plug-in of the microcomputer protection device for power systems cannot protect the CPU during use, so that a large amount of dust contacts the surface of the CPU for a long time, which easily causes damage to the CPU.

[0003] For example, a CPU plug-in of a microcomputer protection device for power systems disclosed in Chinese Patent CN221573110U comprises a CPU and a heat sink, the top end of the CPU is provided with the heat sink, and the CPU plug-in of the microcomputer protection device for power systems further comprises a protection mechanism arranged at the bottom end outside of the heat sink. When the CPU plug-in of the microcomputer protection device for power systems is used, the heat sink is used to conduct heat and dissipate heat for the CPU during use, the protection mechanism is used to protect the surface of the CPU, so that damage to the CPU caused by a large amount of dust contacting the CPU is prevented, and the problem that the CPU cannot be protected during use and a large amount of dust contacts the CPU to cause damage to the CPU is solved by the cooperation of the structures.

[0004] The device in the above file can prevent dust from entering the CPU plug-in and dissipate heat during daily use, but it still has obvious defects in actual use.

[0005] For example, before use, the CPU needs to be installed in the device first, and then the heat sink is fixed on the surface of the CPU by using heat-conducting glue. Although this method can achieve the heat dissipation effect, the installation process in the early stage is relatively complicated, and the heat-conducting glue needs to be removed when the CPU is disassembled later, which is inconvenient to use. In addition, the CPU plug-in needs to be connected to the internal port by using a wire after installation, and the device completely covers the two sides of the CPU plug-in, so that the wire cannot be pulled out and the connection is affected.

[0006] Therefore, a CPU plug-in of a microcomputer protection device for power systems that is convenient to disassemble and assemble is designed to solve such defects. SUMMARY

[0036] The shell 101 of the embodiment is a rectangular metal shell for accommodating and fixing other components.

[0037] The sliding block 102 is a plastic sliding block with a clamping groove 102a, and the number of clamping grooves is eleven, which is located on the upper end surface of the sliding block, and is used for clamping with the clamping block 103.

[0038] The clamping block 103 is an elastic metal clamping block installed inside the shell 101, which can be clamped with the clamping groove 102a on the sliding block 102. The clamping block 103 is designed to reciprocate up and down when the sliding block 102 moves, so as to realize clamping or releasing.

[0039] The elastic mechanism of the embodiment is that the clamping block 103 is elastically installed by the built-in spring, so that it can move under the pushing of the clamping groove 102a, and limit the movement of the sliding block 102 when the movement tendency of the sliding block 102 is weakened.

[0040] In the embodiment, the design of the clamping assembly focuses on the combination of plastic and metal to achieve a balance between cost effectiveness and durability.

[0041] In use, the clamping state can be quickly adjusted through the interaction of the sliding block 102 and the clamping block 103, and the clamping state can be avoided from loosening, so as to improve the stability and reliability of the clamping assembly, and reduce the risk of failure caused by unstable clamping.

[0042] Embodiment 2.

[0043] For the second embodiment of the present application, the embodiment is basically the same as embodiment 1, except that the present embodiment is described as follows.

[0044] In the present embodiment, the shell 101 is a cylindrical metal shell, designed for rotating installation to adapt to different installation directions.

[0060] The compression part 400 is in sliding connection with the second mounting plate 300, and the compression part 400 is also in abutment with the extruding part 201, and the extruding part 201 can extrude the compression part 400 to move towards the lower surface of the chip. By the extruding force of the first mounting plate 200, the second mounting plate 300 is driven to further extrude the chip, and the stability is higher.

[0061] Preferably, the upper surface of the second mounting plate 300 is provided with a receiving cavity 302, the shape of the receiving cavity 302 is rectangular, and a plurality of receiving cavities 302 are arranged.
