Detailed Description

As shown in fig. 1, the present embodiment provides a multi-row bus duct housing, which includes a housing joint 2 and two bus ducts 1 arranged side by side.

Specifically, as shown in fig. 2, each bus duct 1 includes a copper bar housing 11, a left U-shaped plate 12 located on one side of the copper bar housing 11, and a right U-shaped plate 13 located on the other side of the copper bar housing 11, the side wall of the copper bar housing 11 is provided with a plurality of heat dissipation strips 111, the openings of the U-shaped plates face outward, the two sides are vertically symmetrical, the size of the right U-shaped plate 13 is smaller than that of the left U-shaped plate 12, and the bus duct 1 is assembled in the left U-shaped plate 12 of another bus duct 1 through the right U-shaped plate 13 and connected together.

More specifically, as shown in fig. 3, two strip-shaped grooves 3 are respectively formed in a right U-shaped plate 13 and a left U-shaped plate 12 at the connection position of two bus ducts 1, one strip-shaped groove 3 is formed in the right U-shaped plate 13 and the left U-shaped plate 12 which are located at the outer sides, and one end of each strip-shaped groove 3 is open.

More specifically, two rows of heat dissipation strips 111 are arranged on the side wall of the copper bar shell 11, the two rows of heat dissipation strips 111 are vertically symmetrical, the heat dissipation strips 111 are arranged in an L shape, and the end of each heat dissipation strip 111 is arranged in the corresponding strip-shaped groove 3.

More specifically, the shell connects 2 covers in the one end of a plurality of bus ducts 1, the shell connects 2 and locates that one end of bar groove 3 openings, the shell connects 2 shapes and matches with 1 end structure of bus duct, for example, as shown in fig. 4, the right U-shaped plate 13 of two bus duct 1 junctions, the U-shaped plate that 12 length ratios in the outside of left U-shaped plate are little, so the shell connects 2 like the I-shaped, the middle part is empty, four angles all are equipped with the through hole, a U-shaped plate for entangling the bus duct 1 outside, the inner wall is equipped with the fixture block in the middle of the shell connects 2, a breach department for the card is in the middle of two bus ducts 1.
