[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A PDM power distribution unit includes a housing with a hollow interior. Rails are symmetrically mounted on the left and right side plates inside the housing, and a power distribution unit is slidably mounted between the rails. The power distribution unit is used for power distribution and control. A first rectangular hole is provided at the top of the housing, and a protective cover is provided at the top of the housing for electrical isolation, prevention of foreign object intrusion, and arc protection. A second rectangular hole is provided at the bottom of the housing, allowing wire harnesses to pass through.

[0006] By adopting the above technical solutions, the cooperation between the track and the slide rail makes the installation and maintenance of the power distribution unit more convenient, ensuring the stability and flexibility of the power distribution unit in the housing, and meeting a variety of electrical connection requirements. The unique structural design of the protective cover not only achieves a good sealing effect, but also makes it easy for users to open and close quickly, and can also be used for electrical isolation, prevention of foreign object intrusion and arc protection.

[0007] In a further embodiment, the power distribution unit includes a slide rail, a neutral grounding terminal, a grounding terminal, cable clamps, and a guide rail. The slide rail is slidably installed on the rail. A side plate is fixedly installed on the slide rail. A bracket is slidably installed on the top of the side plate. A guide rail is fixedly installed on the top of the bracket. Multiple circuit breakers are detachably installed on the top of the guide rail. A back plate is fixedly installed between the side plates. Guide rails are symmetrically fixedly installed on the front side of the top of the back plate. Multiple neutral grounding terminals are detachably installed on the left side of the guide rail (8). Multiple grounding terminals are detachably installed on the right side of the guide rail. A guide rail is fixedly installed on the front side of the bottom of the back plate. Multiple cable clamps are detachably installed on the guide rail.

[0008] By adopting the above technical solutions, the cooperation between the slide rail and the track improves the convenience of installation and maintenance of the power distribution unit. The setting of multiple sets of zero-row grounding terminals, ground row grounding terminals and cable clamps ensures the safety and reliability of power distribution, avoids cable mess, and effectively prevents the occurrence of electrical faults.

[0009] In a further embodiment, the protective cover is integrally composed of a base and a cover plate. The base is sealed to the housing, and the cover plate is hinged to the base. An integrally formed circular protrusion is provided at the top front end of the base, and an integrally formed rectangular ring is provided at the top front end of the cover plate. The rectangular ring and the circular protrusion are detachably installed.

[0010] The above technical solution achieves a good sealing effect, facilitates quick opening and closing for users, and can also be used for electrical isolation, prevention of foreign object intrusion, and arc protection.

[0011] In a further embodiment, a brush is fixedly installed inside the second rectangular hole, and the brush is used to block foreign objects such as dust and insects from entering the box.

[0012] By adopting the above technical solution, the brush achieves a sealing effect.

[0013] In a further embodiment, ear plates are fixedly installed on the left and right sides of the housing, and mounting holes are symmetrically arranged on the front and back of the ear plates.

[0014] By adopting the above technical solution, the configuration of the ear plate and the installation of the cabinet are facilitated.

[0015] In a further embodiment, the guide rail is elongated and its length direction is consistent with the length direction of the housing.

[0016] By adopting the above technical solutions, it is easier to arrange and manage cables neatly, and space utilization is improved.

[0017] In summary, this utility model has the following beneficial effects: 1. The sliding rails and tracks facilitate the removal of the power distribution unit from the housing, making wiring harness installation more convenient; 2. The brush design helps to prevent dust and foreign objects from entering while also providing heat dissipation. 3. The protective cover provides electrical isolation, protection against foreign object intrusion, and protection against electric arc. Attached Figure Description
