The first embodiment is as follows:

as shown in fig. 1, a first aspect of the present invention provides a stator 100, including: a stator assembly 110 including a plurality of stator windings 111, any one of the stator windings 111 being provided with a winding connector 112; and a terminal plate 120 provided to the stator assembly 110, wherein any one of the winding connectors 112 is connected to the terminal plate 120 so that the plurality of winding connectors 112 are electrically connected to each other.

The stator 100 proposed in the present application includes a stator assembly 110, the stator assembly 110 includes a plurality of stator windings 111, where the number of the stator windings 111 is multiple, and any one of the stator windings 111 is provided with a winding connector 112, and in order to enable the stator winding 111 to be connected to a power supply, the plurality of winding connectors 112 need to be connected to a power supply line 130. The power line 130 has one end connected to a power source and the other end capable of being electrically connected to the winding connections 112 of the plurality of stator windings 111, so that the winding connections 112 are electrically connected to the power source. Understandably, the stator winding 111 of the stator assembly 110 has a larger number of stator windings 111, which results in a larger number of winding joints 112, and the stator windings 111 are usually made of enameled wires, which results in a lower production efficiency if the winding joints 112 of a plurality of enameled wires are connected together, which is difficult to work. In order to avoid the above problems, the present application provides the terminal plate 120 for electrically connecting the plurality of winding connectors 112 in the stator 100, so as to reduce the difficulty of electrically connecting the plurality of winding connectors 112 with the power line 130 and improve the production efficiency.

Further, in order to achieve an electrically conductive connection between the plurality of winding connections 112, a terminal plate 120 is also provided in the stator 100. The terminal plate 120 is disposed on the stator assembly 110, any winding connector 112 is connected to the terminal plate 120, and at least a part of the structure of the terminal plate 120 is made of a metal material or a conductive material, so that the conductive connection between the winding connectors 112 can be realized through the terminal plate 120. Understandably, since at least a portion of the terminal block 120 is configured as a conductor, the winding tabs 112 can be connected to a plurality of locations on the terminal block 120 for wiring without bundling the plurality of winding tabs 112 together to enable conductive connection between the plurality of winding tabs 112. Further, the terminal plate 120 can be connected to the power line 130 to provide an electrically conductive connection of the plurality of stator windings 111 to the power source. In this manner, the difficulty of conductively connecting the plurality of winding connections 112 to the power line 130 is reduced, and the production efficiency of the stator 100 is improved.

Through set up the wiring dish 120 in stator 100 to link to each other a plurality of winding joints 112 in the stator module 110 with the wiring dish 120, accessible wiring dish 120 is with a plurality of winding joints 112 conductive connection, so, can need not to tie a plurality of winding joints 112 together and can enough realize the conductive connection between a plurality of winding joints 112, and then realize the conductive connection between a plurality of winding joints 112 and the power through wiring dish 120, reduced the degree of difficulty with a plurality of winding joints 112 and power cord 130 conductive connection, improved stator 100's production efficiency.

The second embodiment:

as shown in fig. 1 and 3, in a specific embodiment based on the first embodiment, the patch panel 120 includes: a body 121; a plurality of terminals 122, arbitrary terminal 122 protrusion is located main part 121, and a plurality of terminal 122 mutual conductive connection, a plurality of winding connectors 112 and a plurality of terminal 122 one-to-one set up, and arbitrary winding connector 112 is connected in corresponding terminal 122.

In this embodiment, the structure of the pad 120 is defined. The terminal block 120 includes a body 121 and a plurality of terminals 122, wherein the terminals 122 are configured to be connected to the winding connections 112. Specifically, the terminal 122 is connected to the body 121, and in order to facilitate connecting the winding connector 112 to the terminal 122, the terminal 122 is disposed to protrude from the body 121, so that the winding connector 112 can be conveniently wound on the terminal 122. The number of the terminals 122 is plural, and any winding connector 112 can be wound on the corresponding terminal 122. After the winding tabs 112 are wound around the corresponding terminals 122, in order to ensure a firm connection between the winding tabs 112 and the terminals 122 and to ensure that no virtual connection occurs between the winding tabs 112 and the terminals 122, the winding tabs 112 may be continuously melted or soldered to the terminals 122. The operation can adopt automatic batch operation, and the production efficiency is improved.

Further, in order to enable the conductive connection between the winding connectors 112 connected to the terminals 122, the present application sets the terminals 122 in the terminal block 120 to be electrically connected to each other, so that the winding connectors 112 can be electrically connected through the connection sets connected thereto. Specifically, the posts 122 and the main body 121 are made of a conductive metal material, or made of other conductive materials, and as the posts 122 are connected to the main body 121, a conductive connection can be achieved between the posts 122 through the main body 121, and thus a conductive connection between the winding connectors 112 can be achieved.

The terminal 122 may be integrally formed with the body 121 by press molding, the terminal 122 may also be formed by winding, and the terminal 122 may also be separately processed into a component and then welded to the body 121.

By providing a plurality of terminals 122 in the terminal plate 120, the winding connections 112 can be connected to the respective terminals 122, and the respective winding connections 112 can be electrically connected to one another by the terminals 122 being electrically conductively connected to one another. By connecting the winding connector 112 to the terminal 122, the connection between the winding connector 112 and the terminal board 120 can be more secure and reliable, and the automation can be facilitated.

Further, the plurality of posts 122 are spaced apart from each other.

In this embodiment, the plurality of posts 122 are spaced apart from one another. Understandably, in the case that two adjacent winding joints 112 are electrically connected to the power supply, if the distance between the two winding joints 112 is too small, the air between the two winding joints 112 is easily broken down by voltage, and an electric spark is generated, thereby causing an auto-ignition accident. In order to avoid the above problem, a certain distance is provided between any two adjacent binding posts 122 in the present application, so that air insulation between two adjacent winding joints 112 can be achieved, and safety and reliability of the stator 100 are improved.

Further, if two adjacent terminals 122 are too small in distance, the winding connector 112 is not convenient to be wound on the terminals 122, and therefore, the winding connector 112 can be conveniently wound on the terminals 122 by setting a certain distance between any two adjacent terminals 122, so that the operation difficulty is reduced, and the production efficiency is improved.

Specifically, the mounting member 123 is made of a metal material capable of conducting electricity or other materials capable of conducting electricity, so that a plurality of posts 122 connected to the same mounting member 123 can be electrically connected to each other. Understandably, by sequentially arranging the plurality of mounting pieces 123 in the radial direction of the lug plate 120, the space occupied by the plurality of mounting pieces 123 can be reduced, so that the mounting pieces 123 for mounting the posts 122 can be arranged as much as possible on the limited area of the lug plate 120, and further more posts 122 are arranged in the lug plate 120. Moreover, by sequentially arranging the mounting pieces 123 along the radial direction of the patch panel 120, the terminals 122 can be more dispersedly arranged on the mounting pieces 123, so as to increase the distance between two connected terminals 122, avoid air breakdown between two adjacent winding connectors, and improve the safety and reliability of the stator 100.

Understandably, any stator winding 111 includes one or more winding joints 112, and in the case that any stator winding 111 includes a plurality of winding joints 112, it is necessary to maintain a certain distance between the plurality of winding joints 112 in one stator winding 111 to avoid the problem of air breakdown between the plurality of winding joints 112 due to poor insulation. In order to avoid the above problem, the present application defines the relative positions of the plurality of terminals 122 connected to the winding joints 112 of any one of the stator windings 111, and specifically, the plurality of terminals 122 corresponding to the winding joints 112 of any one of the stator windings 111 have a distance therebetween in the radial direction of the terminal block 120 and in the circumferential direction of the terminal block 120, so that not only a certain distance is provided between the plurality of winding joints 112, but also since the respective terminals 122 have a distance therebetween in the circumferential direction of the terminal block 120, it is possible to ensure that the respective winding joints 112 extend in different directions, and prevent the respective winding joints 112 from overlapping in the radial direction of the terminal block 120.

Through setting up a plurality of terminals 122 that winding joint 112 of arbitrary stator winding 111 corresponds to each other and all have the interval along the radial and circumference of terminal plate 120, can guarantee that each winding joint 112 of same stator winding 111 has certain interval each other, and can guarantee that each winding joint 112 extends along different directions, prevent that each winding joint 112 from appearing overlapping along the radial direction of terminal plate 120, so, can guarantee to have sufficient air insulation layer between each winding joint 112, promote stator 100's security and reliability.
