[0002] A power module is a device that provides a stable current to an equipment. The power module is connected to the power supply through a connection port or plug-in port, and the other end of the connection port is plugged into the electrical equipment. The connection port consists of conductive plates or conductive posts.

[0003] In actual use, it was found that the external terminals move relative to each other when plugged in or disconnected. Due to the high voltage, current is generated during the relative movement, which breaks down the air and generates an electric arc. The generation of the electric arc will damage the power module body.

[0004] To address this, a power module with external protection is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a power module with external protection. By setting multiple plug holes on the cover plate and setting an insulating plate between every two adjacent plug holes, the insulating plate can block the current to prevent the generation of electric arc, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power module with external protection includes a housing, a cover plate, and a module body. The housing contains multiple insulating posts, each with a threaded fixing post at its top. The module body is fixedly mounted on the insulating posts. The cover plate is fixedly mounted on the top wall of the housing by screws. The module body has multiple terminal blocks, and the cover plate has multiple corresponding insertion holes. Multiple insulating plates are spaced apart on the cover plate, each insulating plate corresponding to two adjacent insertion holes.

[0008] Preferably, multiple insertion blocks are fixedly installed on the top walls of both sides of the outer casing, and multiple insertion slots corresponding to the insertion blocks are provided on the cover plate.

[0009] Preferably, a plurality of the insulating posts are distributed around the perimeter of the interior of the housing, the insulating posts are made of hard rubber material, and the fixing posts are provided with annular flanges.

[0010] Preferably, the cover plate is provided with a plurality of sliding grooves spaced apart, and a plurality of springs are fixedly connected to the side of the cover plate facing the outer shell. Every two springs are distributed at the two ends of the sliding grooves respectively. Each insulating plate is slidably disposed on each sliding groove, and one end of the spring is fixedly connected to the insulating plate.

[0011] Preferably, the surface of the insert is coated with tin.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The cover plate has multiple plug holes. The terminals on the module body pass through the plug holes to connect with the external wiring device. An insulating plate is set between each plug hole so that the insulating plate isolates each two adjacent terminals and prevents the generation of electric arc, thus protecting the power module.

[0014] 2. A spring is installed between the insulating plate and the cover plate, which allows the insulating plate to slide and reset itself. This prevents interference when the terminal block is connected to an external wiring device and maintains isolation at all times. Attached Figure Description

[0021] Please see Figures 1 to 4 This utility model provides a power module with external protection, the technical solution of which is as follows:

[0022] A power module with external protection includes a housing 1, a cover plate 3, and a module body 4. The housing 1 has multiple insulating posts 9 inside, and the top of each insulating post 9 is threadedly connected to a fixing post 12. The module body 4 is fixedly mounted on the insulating posts 9. The cover plate 3 is fixedly mounted on the top wall of the housing 1 by screws. The module body 4 has multiple terminal posts 7. The cover plate 3 has multiple corresponding insertion holes 6. The cover plate 3 has multiple insulating plates 5 spaced apart, with each insulating plate 5 located between two adjacent insertion holes 6.

[0023] The terminal 7 on the module body 4 is connected to the insertion hole 6 on the cover plate 3. Since an insulating plate 5 is provided between each adjacent insertion hole 6, the insulating plate 5 is made of high alumina oxide ceramic material pressed and sintered. The insulating plate 5 separates the adjacent insertion holes 6. After the terminal 7 is inserted, it can form an isolation effect on the two adjacent terminal 7 to prevent current backflow and generate an electric arc.

[0024] Both the outer shell 1 and the cover plate 3 are made of copper, which has good heat dissipation performance.

[0025] like Figure 1 As shown, multiple insert blocks 2 are fixedly installed on the top walls of both sides of the outer shell 1. Multiple insertion slots 8 corresponding to the insert blocks 2 are opened on the cover plate 3. The top of the outer shell 1 is provided with threaded holes, and the cover plate 3 is also provided with threaded holes. The cover plate 3 is fixedly connected to the outer shell 1 by screws.

[0026] During installation, align the insertion slot 8 on the cover plate 3 with the insertion block 2, and insert the insertion block 2 into the fixing slot. During installation, weld the insertion block 2 to the corresponding equipment to make it more stable and have a good anti-vibration effect.

[0027] like Figure 1 and Figure 3 As shown, the outer casing 1 has multiple insulating posts 9 inside, and the top of each insulating post 9 is threadedly connected to a fixing post 12.

[0028] Multiple insulating posts 9 are distributed around the inside of the outer casing 1. The insulating posts 9 are made of hard rubber material, and the fixing posts 12 are provided with annular flanges 14.

[0029] The module body 4 is also provided with multiple positioning holes 13 that cooperate with the fixing post 12. During installation, the positioning holes on the module body 4 are aligned with the insulating post 12, and the fixing post 12 is screwed into the post through the positioning holes, so that the bottom of the annular flange 14 contacts the surface of the module body 4. In this way, the annular flange 14 forms pressure to fix the module body 4, ensuring the stability of the module body 4 during installation.

[0030] The insulating post 9 is made of hard rubber material and has good insulation properties. The insulating post 9 separates the module body 4 from the outer shell 1.

[0032] A sliding groove 10 is provided, and the insulating plate 5 is slidably installed on the sliding groove 10. A spring 11 is also provided between the insulating plate 5 and the cover plate 3. When the external wiring device is connected to the terminal 7, its bottom contacts the top of the insulating plate 5 and applies pressure to the insulating plate 5, thereby pulling the spring 11. When the external wiring device is disconnected from the terminal 7, the insulating plate 5 returns to its original position under the pushing force of the spring 11. While ensuring smooth wiring, it can also maintain an isolation function at all times to prevent the generation of electric arc.

[0033] The surface of the insert 2 is coated with tin, and the surface of the fixing foot 4 is coated with tin. During processing, the tin can be applied to facilitate soldering with the equipment.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
