Problems solved by technology

However, the use of aluminum coils has the following problems: due to the characteristics of the aluminum coil material itself, compared with the copper coil, it is easy to fall off when it is connected to the terminal, and it is easily damaged by external moisture erosion, resulting in the contact part falling off , so it is currently impossible to produce household motors with aluminum coils

Embodiment Construction

[0015] As shown in FIGS. 1 to 3 , the household motor 50 provided by the present invention is provided with a terminal 10 , and the terminal 10 can power on the drive shaft 30 disposed on the magnetic core 20 to make the drive shaft 30 rotate.

[0016] The coil used for the above-mentioned household motor 50 is an aluminum coil 40. The connection method between the aluminum coil 40 and the terminal 10 is to first weld the aluminum coil 40 on the terminal 10 to form a welding part 41, and then coat the welding part 41 with One layer of epoxy resin layer 42 has anti-corrosion effect, and finally, the outer cover of epoxy resin layer 42 is covered with a cover 43 capable of buffering the impact force suffered by epoxy resin layer 42 and sealing it.

[0017] The household motor 50 provided by the present invention will be described in detail below.

[0018] In the present invention, the aluminum coil 40 is connected to the terminal 10 of the household motor 50 by welding to form a...

Abstract

The invention discloses a method for connecting aluminium coil of domestic appliances, wherein the method comprises welding the aluminium coil on terminal to form a welding portion, and then coating epoxy resin layer which has corrosion behavior on the welding portion, finally covering a cover which can cushion impact force which is acted on the epoxy resin layer and seal the epoxy resin layer on the outer portion of the epoxy resin layer. The invention provides the method for connecting aluminium coil of domestic appliance which utilizes the epoxy resin layer and a cover to protect the aluminium coil which is contacted with the terminal, therefore, the problem of abscission which is caused by corrosion and the external impact force of the aluminium coil can be prevented, so durability of the product can be increased. Furthermore, the cost of the aluminium coil is less than the copper coil, and a motor which uses the aluminium coil has the same service life as the motor which uses common copper coil, therefore the domestic appliance can be produced through adopting the aluminium coil which can not be used until now.

Description

technical field [0001] The invention relates to a method for connecting an aluminum coil of a household motor, in particular to a method for welding the terminal and the aluminum coil, coating a layer of epoxy resin on the welded part, and then covering the outside of the coating with a cover to prevent A method of connecting aluminum coils of household electric motors where the connecting parts are peeled off or damaged due to corrosion. Background technique [0002] In common household motors, copper wires are wound on a magnetic core with a laminated structure to form a copper coil, and the ends of the copper wires are connected to terminals, and the power is turned on through the terminals. [0003] Since this kind of household motor winds the expensive copper wire on the magnetic core, the production cost of the household motor will be increased. Therefore, in order to reduce costs, aluminum coils can be used instead of copper coils. However, the use of aluminum coils...
