Description

Technical Field

[0001] The utility model relates to a packaging structure for a bathroom exhaust fan motor. Background Art

[0002] The CWIM motor for bathroom exhaust fans is hard to bend because the leads and fuses are connected by crimping terminals and heat shrink tubing, which makes the leads difficult to bend and the fuse connection easily damaged. 1) If the motor is transported and packaged according to the general lower positioning cardboard + tic-tac-toe partition support and fixation solution, the motor leads will be difficult to pack and place and the fuse connection will be damaged. 2) The position of the customer's installation screws for this type of motor is not consistent with the position of the protruding corner of the lower end cover to fix and fasten the end cover, and it is difficult to meet the requirements of all products using conventional positioning solutions. 3) The conventional solution requires multiple customer installation screws and shaft exit holes to be opened on the positioning plate, which will cause the supplier to have a large workload of die-cutting and waste discharge during the processing and production of the positioning cardboard, which is time-consuming and has poor processing and manufacturing processability. 4) The upper and lower motors are stacked vertically in the conventional solution packaging, and the shaft extension of the lower motor is stacked without misalignment with the upper motor body, resulting in low longitudinal space utilization, a small number of units installed per tray, and high packaging and transportation costs.
