Description

Technical Field

[0001] This utility model relates to the field of power module technology, and in particular to a power module with a protective structure. Background Technology

[0002] A power supply module is a power supply that can be directly mounted on a printed circuit board. Its main function is to convert the input power into an output power suitable for the target device. Simultaneously, the power supply module can filter and regulate the input power to ensure the quality and stability of the output power. Through specific circuit structures and component combinations, it achieves the conversion and distribution of electrical energy. It can provide a stable and reliable power supply for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads.

[0003] However, the existing power module interfaces lack adequate protection, there is no good guiding structure when external wires are connected, and there is no good restraint after the external wires are connected, making them easy to pull out under force. In addition, the power module also lacks a good heat dissipation structure, and the internal heat will affect the use of the power module due to long-term heat accumulation. Summary of the Invention

[0004] The main objective of this invention is to provide a power module with a protective structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A power module with a protective structure includes a power module, a connector fixedly installed on the front of the lower inner wall of the power module, an installation cover fixedly installed on the upper end of the power module, a plurality of No. 1 openings on the upper front end of the installation cover, a No. 2 opening on the rear upper end of the installation cover, a heat dissipation device fixedly installed on the rear left end of the power module, and a heat conduction device fixedly installed on the middle left end of the power module.

[0007] Preferably, a plurality of terminals are fixedly installed on the upper end of the connector. A mounting plate is fixedly installed on the upper left and upper right sides of the connector. The mounting plate has a plurality of mounting grooves at its upper end. Anti-slip sleeves are fixedly installed in each of the mounting grooves. Anti-slip protrusions are fixedly installed on the inner walls of each of the anti-slip sleeves. A silicone ring is fixedly installed at the upper end of each of the mounting grooves. When an external wire needs to be inserted into a terminal, the mounting plate and its mounting grooves not only serve as a guide, but also, after the external wire passes through the mounting groove and connects with the terminal, the anti-slip sleeves in the mounting groove and the anti-slip protrusions on their inner walls effectively limit and lock the external wire, making it difficult to pull out. In addition, the silicone ring at the upper end of the mounting groove effectively reduces wear at the connection point between the external wire and the mounting groove.

[0008] Preferably, the heat dissipation device includes a mounting base and a fan. Mounting screws are installed on both the left and right sides of the fan's front end. The fan is fixedly mounted on the front end of the mounting base using these screws, and the mounting base is fixedly mounted on the rear left side of the power module. The fan rotates and blows air through the vents on the heat-conducting plate, further accelerating the heat dissipation speed of the heat-conducting plate.

[0009] Preferably, the heat-conducting device includes two fixing plates, and a plurality of heat-conducting plates are fixedly installed between the two fixing plates. Each heat-conducting plate has a set of ventilation openings at its front end. The two fixing plates are respectively fixedly installed on the upper left and lower left ends of the power module. Because the heat-conducting plates are in contact with the heating elements inside the power module, and the heat-conducting plates are made of copper, they can quickly dissipate heat from the power module.

[0010] Preferably, the mounting slot corresponds vertically to the position of the wiring terminal.

[0011] Preferably, a plurality of the anti-slip protrusions are arranged in a ring within the anti-slip sleeve, and the anti-slip protrusions are made of rubber.

[0012] Preferably, the mounting base is provided with a power supply, the power supply is provided with a switch, and the power supply and the fan are electrically connected.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A mounting plate is provided on the connector. The mounting groove on the mounting plate corresponds vertically to the position of the wiring terminal on the connector. When the external wiring needs to be inserted into the wiring terminal, the mounting plate and its mounting groove not only serve as a guide, but also, after the external wiring passes through the mounting groove and connects with the wiring terminal, the anti-slip sleeve in the mounting groove and several anti-slip protrusions on its inner wall can effectively limit and lock the external wiring, making it difficult to pull out. In addition, a silicone ring is provided at the upper end of the mounting groove, which can effectively reduce the wear at the connection between the external wiring and the mounting groove, further improving the performance of the device.

[0015] 2. The heat-conducting plate on the heat-conducting device is attached to the heat-generating element inside the power module. The heat-conducting plate is made of copper. Therefore, the heat-conducting plate can quickly conduct heat out of the power module. At the same time, the fan on the heat dissipation device rotates and blows air out through the ventilation holes on the heat-conducting plate, thereby further accelerating the heat dissipation speed of the heat-conducting plate and improving the heat dissipation effect of the device.

An installation cover 5 is fixedly installed on the upper end of the power module 1. Several No. 1 ports 6 are opened on the upper front end of the installation cover 5. A No. 2 port 7 is opened on the rear upper end of the installation cover 5. A heat dissipation device 3 is fixedly installed on the rear left end of the power module 1. A heat conduction device 4 is fixedly installed on the middle left end of the power module 1.

[0026] A number of terminals 20 are fixedly installed on the upper end of connector 2. A mounting plate 21 is fixedly installed on the upper left and upper right parts of connector 2. A number of mounting grooves 22 are opened on the upper end of mounting plate 21. Anti-slip sleeves 23 are fixedly installed in each of the mounting grooves 22. A number of anti-slip protrusions 24 are fixedly installed on the inner wall of each of the anti-slip sleeves 23. A silicone ring 25 is fixedly installed on the upper end of each of the mounting grooves 22. The mounting grooves 22 correspond vertically to the terminals 20. The anti-slip protrusions 24 are arranged in a ring inside the anti-slip sleeves 23, and the anti-slip protrusions 24 are made of rubber. When external wiring needs to be inserted into terminal 20, the mounting plate 21 and its mounting groove 22 not only serve as a guide, but also, when the external wiring passes through the mounting groove 22 and connects with terminal 20, the anti-slip sleeve 23 in the mounting groove 22 and several anti-slip protrusions 24 on its inner wall can effectively limit and lock the external wiring, making it difficult to pull out. In addition, a silicone ring 25 is provided at the upper end of the mounting groove 22, which can effectively reduce wear at the connection between the external wiring and the mounting groove 22.

[0027] The heat dissipation device 3 includes a mounting base 30 and a fan 31. Mounting screws 32 are installed on both the left and right front ends of the fan 31. The fan 31 is fixedly mounted on the front end of the mounting base 30 using the mounting screws 32. The mounting base 30 is fixedly mounted on the rear left end of the power module 1. A power supply with a switch is installed on the mounting base 30, and the power supply is electrically connected to the fan 31. The fan 31 rotates and blows air, which is then expelled through the vents 42 on the heat-conducting plate 41, further accelerating the heat dissipation speed of the heat-conducting plate 41.

[0028] The heat conduction device 4 includes two fixing plates 40. Several heat conduction plates 41 are fixedly installed between the two fixing plates 40. Each heat conduction plate 41 has a set of ventilation openings 42 at its front end. The two fixing plates 40 are respectively fixedly installed on the upper left and lower left sides of the power module 1.

The heat-conducting plate 41 on the heat-conducting device 4 is attached to the heating element inside the power module 1, and the heat-conducting plate 41 is made of copper. Therefore, the heat-conducting plate 41 can quickly dissipate heat from the power module 1. Simultaneously, the fan 31 on the heat dissipation device 3 rotates and blows air, which is then blown out through the vent 42 on the heat-conducting plate 41, further accelerating the heat dissipation speed of the heat-conducting plate 41 and improving the heat dissipation effect of the device. In addition, a mounting plate 21 is provided on the connector 2, and the mounting groove 22 on the mounting plate 21 connects to the connector 2. The terminals 20 on the mounting plate are positioned vertically and vertically. When an external wire needs to be inserted into a terminal 20, the mounting plate 21 and its mounting groove 22 not only serve as a guide, but also, when the external wire passes through the mounting groove 22 and connects with the terminal 20, the anti-slip sleeve 23 in the mounting groove 22 and several anti-slip protrusions 24 on its inner wall can effectively limit and lock the external wire, making it difficult to pull out. In addition, a silicone ring 25 is provided at the upper end of the mounting groove 22, which can effectively reduce the wear at the connection between the external wire and the mounting groove 22, further improving the performance of the device.
