Abstract
A power distribution unit includes a housing, a cover, and a gasket assembly. The housing, which holds one or more fuses, relays, cables, and busbars, includes a channel located along a perimeter of the housing. The cover is to be placed over the housing. The gasket assembly includes a gasket, multiple gasket ribs, and a gasket connector. The gasket is placed in the channel so that the gasket is sandwiched between the housing and the cover when the cover is placed over the housing. The gasket ribs are located around and attached to the gasket and are placed into gasket rib receivers in the housing. The gasket connector prevents the cover from being secured over the housing without the gasket.
Claims18
A power distribution unit (PDU) comprising:
- a housing comprising a channel disposed along a perimeter of the housing, the housing holding one or more fuses and one or more relays;
- a cover placed over the housing;
- and
- a gasket assembly comprising:
- a gasket placed in the channel, wherein the gasket is sandwiched between the housing and the cover;
- a plurality of gasket ribs disposed around and attached to the gasket, the gasket ribs extending into gasket rib receivers in the housing;
- a gasket connector ensuring the gasket is in the channel before the cover is secured over the housing;
- a pin comprising a cylindrical shaft;
- a base comprising an upper surface orthogonal to the pin and a slanted lower surface;
- a spring wound around the cylindrical shaft;
- and
- a housing cavity comprising:
- a first slanted floor, wherein the slanted lower surface of the pin slides along the first slanted floor;
- a second slanted floor disposed beneath the first slanted floor, wherein a bottom portion of the pin slides along the second slanted floor;
- and
- a pin stop located at one end of the second slanted floor, wherein the pin rests in the pin stop when in a first position.
A power distribution unit (PDU) comprising:
- a housing holding one or more fuses and one or more relays, the housing comprising a first side, a second side perpendicular to the first side, a third side perpendicular to the second side and parallel to the first side, and a fourth side perpendicular to the first side and parallel to the second side, the housing further comprising:
- a first rib disposed on an inside wall of the first side, wherein the first rib is trapezoid-shaped;
- a second rib disposed on an inside wall of the second side, wherein the second rib is trapezoid-shaped;
- and
- a top frame disposed over the first rib and the second rib, the top frame being perpendicular to the first side and the third side;
- a cover secured over an opening of the housing;
- and
- a gasket sandwiched between the housing and the cover, the gasket forming an airtight seal between the housing and the cover.
