Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and in particular relates to an interference fit waterproof bus duct. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to the on-site installation and construction connection. The waterproof busbar body trough in the prior art does not protect the internal busbar body, resulting in wear between the busbar body and the mounting plate when the busbar body is installed. The current busbar body trough is composed of multiple plates connected, and there will be gaps at the connection. Water seepage is inevitable when used outdoors.

[0003] To this end, a waterproof busbar duct device with the announcement number "CN114614419A" includes a bottom mounting plate, the left and right sides of the bottom mounting plate are fixedly connected with a first waterproof sheet, the right side of the first waterproof sheet on the right side is fixedly connected with a right mounting plate, the left side of the first waterproof sheet on the left side is fixedly connected with a left mounting plate, the top of the bottom mounting plate is movably connected with three busbar bodies, and the top mounting plate is fixedly connected between the left mounting plate and the right mounting plate. The waterproof busbar duct device can fix the position of the busbar body by setting a fixing mechanism to prevent the busbar body from shifting in the inner cavity.

[0004] For the above-mentioned waterproof bus duct device, although the second screw and the second nut are set to squeeze the waterproof sheet at the connection during the connection of the mounting plate, so as to seal the gap at the connection and further ensure the sealing effect, the following obvious defects still exist during use: the above-mentioned bus duct is locked on the left and right mounting side plates by fixing the first waterproof sheet and the second waterproof sheet with the second screw and the second nut. However, the second screw and the second nut will rust and cannot be removed due to long-term influence of external rain and environment, and the sealing between the left and right side plates and the upper and lower mounting plates will be reduced, resulting in water seepage.
