[0022] The utility model will be further described below in conjunction with the accompanying drawings of the specification.

[0023] like Figures 1 to 5As shown, the utility model is a protective shell of a DC shunt metering module, including an upper shell 2, a lower shell 3 and a positioning unit, the lower shell 3 is provided with lower rivet studs 9 at four corners, the upper shell 2 is provided with upper rivet studs 8 corresponding to the lower rivet studs 9 of the lower shell 3, the circuit board 6 of the DC shunt metering module is provided with openings corresponding to the positions of the upper rivet studs 8 and the lower rivet studs 9, the upper rivet studs 8 and the lower rivet studs 9 are clamped through the openings on the circuit board 6, and are fixedly connected by nuts; the upper shell 2 and the lower shell 3 are fixedly connected to form a shell 1, and the shell 1 is made of insulating material.

[0024] The upper shell 2 is convex-shaped, and the lower shell 3 is concave-shaped. The four sides of the upper shell 2 and the lower shell 3 are snapped together and fixed to a designated position by a positioning unit provided below the lower shell 3.

[0025] like Figure 1 and 5 As shown, the upper shell 2 is provided with holes corresponding to the power terminal 5, the load terminal 4, the connection terminal 13, and the indicator light 14 of the DC shunt metering module.

[0026] like Figure 3 and 5 As shown, a lower support 10 for supporting the lower side of the circuit board is provided inside the lower shell 3, and an upper support 7 for supporting the upper side of the circuit board is provided inside the upper shell 2.

[0027] like Figure 6-7 As shown, the positioning unit includes a sliding buckle 11 and a metal guide rail 12, and the sliding buckle 11 and the metal guide rail 12 are respectively slidably connected to the bottom of the lower shell 3 in the horizontal and vertical directions. The sliding buckle 11 is clamped with the metal guide rail 12, and the metal guide rail 12 is provided with a fixing hole for fixing to a wall or other products.
