Description

Technical Field

[0001] The utility model relates to the field of electromechanics, in particular to a novel motor winding frame. Background Art

[0002] In the prior art, in order to save space and materials, the motor protection cover of the floor fan is only large enough to cover the motor winding. This structure easily leads to a small gap between the winding and the motor protection cover. During use, due to various human or objective reasons, the coil of the motor winding and the motor protection cover may easily come into contact, which may easily cause leakage or short circuit, posing a threat to human safety and home safety.

[0003] Based on the above problems, people in the industry have made improvements to the motor winding frame of the prior art, such as a motor winding frame disclosed in a Chinese patent, patent number: 202020675917.2, comprising a winding device (1) and a plurality of terminals (11) fixed to the upper edge of the winding device, characterized in that the winding device (1) is also buckled with a protective device (2) for separating the coil and the motor housing; the protective device (2) comprises a wall (21) and a baffle (25) fixed on the wall (21), the baffle (25) being installed between every two terminals (11) for separating the wire segments connected to the terminals (11); the wall (21) is provided with a buckling groove (211) for buckling, and a sliding groove (212) adapted to the buckling groove (211) is provided at a position corresponding to the buckling groove (211) on the winding device (1).

[0004] The above patent adds a protective device on the motor winding frame to prevent the winding coil from contacting the motor protection cover. The protective device is also provided with a baffle and a slot. The baffle is used to separate the windings connected to the terminal so that they do not get entangled with each other. The slot is used to store the windings connected to the terminal, thereby improving the utilization rate of the copper wire and increasing the electrical safety characteristics of the product during use.

[0005] Although the above patent solves the problem of contact between the coil and the motor protection cover in the prior art, it still has the following problems: (1) The protective device 2 is fixed to the upper winding portion 12 by the snap-fit ​​connection of the buckle groove 211 and the slide groove 212. During the production process, the motor winding frame is installed with the coil and then installed with the motor protection cover. The motor protection cover includes an upper cover and a lower cover. After the motor winding frame is fixed by the motor protection cover, the protective device 2 can be firmly surrounded and fixed (the upper cover can surround and fix the protective device 2), thereby preventing the protective device 2 from falling during transportation. However, if the protective cover used in some motors does not have an upper cover or uses an open upper cover (open The upper cover refers to an opening provided at a certain position. Not providing an upper cover or using an open upper cover can meet the needs of customers. Otherwise, the protective device 2 will leak out. Since the structure adopts a snap-on (button-on) method (which is not completely firm), the protective device 2 may fall off during transportation. (2) In the above patent, because a card slot 23 is provided, the card slot 23 not only exposes the terminal 11, but also, after wiring, the wire part will also be exposed through the card slot 23. If the protective cover used in some motors does not have an upper cover or uses an open upper cover, it is easy to be contacted by external wires, resulting in a short circuit. (3) Simply using the heat dissipation slot 134 for heat dissipation results in poor heat dissipation effect.

[0006] Based on the above problems, we propose a new type of motor winding frame. Utility Model Content

[0033] As a preferred embodiment; the protective device 2 also includes a baffle 17 and a connecting block 18, and the upper winding portion 3 is also provided with a slot 19 corresponding to the connecting block 18; the baffle 17 and the connecting block 18 are respectively arranged on the inner side of the wall 7, and the wall 7, the baffle 17, the connecting block 18, the protective surface 6 and the connecting portion 8 are an integrally formed structure; by providing the baffle 17, the windings of each terminal 5 can be separated so that they are not entangled with each other; in addition, by providing the connecting block 18 and the slot 19, the connecting block 18 is snapped into the slot 19, so that during the assembly process, the protective device 2 can be preliminarily snapped onto the upper winding portion 3 before the subsequent binding is performed.

[0034] As a preferred embodiment; the first connecting groove 11 and the second connecting groove 12 are both arranged close to the wall 7; the purpose of this design is: because the first connecting groove 11 corresponds to the third connecting groove 13, and the second connecting groove 12 corresponds to the fourth connecting groove 14, the third connecting groove 13 and the fourth connecting groove 14 are arranged closer to the terminal posts 5 at both ends, which not only makes the connection more compact, but also the binding and stabilizing effect of the protective device 2 is better, and the binding strap is not easy to detach from the first connecting ear 9 or the second connecting ear 10.

[0035] As a preferred embodiment; the protective surface 6 and the wall 7 are vertically arranged; the protective surface 6 extends upward around the center of the portion 3 and covers the terminal 5; it can be understood that the protective surface 6 can effectively cover the terminal 5, while also covering the wires routed from the side, so that the terminal 5 and the wires connected thereto will not be exposed, and when applied to a motor protection cover without an upper cover, the wires and the terminal 5 will not be exposed, thereby avoiding contact with external wires and causing a short circuit.

[0038] It should be pointed out that the main problems existing in the prior art are: first, if the protective cover used does not have an upper cover or an open upper cover is used, the protective device in the prior art will leak out. Since the connection structure of the protective device in the prior art adopts a snap-on (buckle) method (which is not completely firm), the protective device may fall off during transportation; second, the terminal and the wire will be exposed and easily contacted by the external wire; third, the heat dissipation effect of the heat dissipation slot is poor;

[0039] Therefore, through the improvements of the present application, firstly, the protective device 2 can be effectively fixed, so that it can not only be applied to the motor protective cover with an upper cover, but also, when applied to the motor protective cover without an upper cover, the protective device 2 will not fall off during transportation; secondly, when applied to the motor protective cover without an upper cover, the wires and the terminal 5 will not be exposed, so as to avoid short circuit caused by contact with the external line; thirdly, after being connected with the lower cover, a circular heat dissipation gap channel can be created between the bottom cover 15 and the inner bottom surface of the lower cover, and compared with the heat dissipation groove in the prior art, the heat dissipation effect is greatly improved.
