Busbar including blade
The present invention provides a busbar comprising terminals, a body connected to the terminals and includes a plurality of blades, wherein the body includes an inner body, an outer body, and connecting parts, the outer body is disposed outside the inner body, the connecting parts are arranged in a periphery of the inner body at regular intervals and connect the inner body to the outer body, the terminals are disposed in the inner body so that connection ends of the terminals are disposed between the adjacent connecting parts, the plurality of blades protrude from an upper surface of the outer body and are arranged in a circumferential direction with respect to a center of the busbar, the outer body includes a cooling hole formed to pass through from a lower surface thereof to the upper surface, and the cooling hole is disposed between adjacent blades, thereby providing an advantageous effect of reducing the number of parts to be manufactured such that manufacturing costs and manufacturing processes can be reduced.
1. A busbar comprising:
terminals; and
a body connected to the terminals and including a plurality of blades,
wherein the body includes an inner body, an outer body, and connecting parts,
the outer body is disposed outside the inner body,
the connecting parts are arranged in a periphery of the inner body at regular intervals and connect the inner body to the outer body,
the terminals are disposed in the inner body so that connection ends of the terminals are disposed between adjacent connecting parts,
the plurality of blades protrude from an upper surface of the outer body and are arranged in a circumferential direction with respect to a center of the busbar,
the outer body includes a cooling hole formed to pass through from a lower surface of the outer body to the upper surface, and
the cooling hole is disposed between adjacent blades.
2. The busbar of claim 1 , wherein the inner body includes a hole formed at a center of the busbar.
3. The busbar of claim 1 , wherein the blades are formed to be inclined so as to form an angle of attack with respect to a reference line formed in a radial direction at a center of the busbar.
4. The busbar of claim 1 , wherein:
the terminals include a terminal body formed in an annular shape; and
the connection ends of the terminals are arranged in a periphery of the terminal body.
5. The busbar of claim 1 , wherein the body and the blades are integrally formed, and the terminals are integrally formed with the body.
