[0019] In one possible implementation, the first mounting component includes:

[0020] A first mounting plate is installed at the end of the annular stator. The first mounting plate has several circular holes, and a connector is installed in a portion of the circular holes.

[0021] Several circular plates are installed in the remaining circular holes, and a rectangular limiting frame is installed on the top of the circular plates;

Detailed Implementation

[0046] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please refer to Figures 1-10 The present invention will now describe a solderless terminal connector for a motor, as disclosed in this invention. Figures 1-2The structure includes an end cap 1, a housing 2, an inlet port 3, an extension plate 4, an annular stator 5, a second mounting piece 6, connectors 7, and a first mounting piece 8. Several extension plates 4 are mounted on the outer wall of the housing 2, with one end of each extension plate 4 flush with one end face of the housing 2. The end cap 1 is mounted on the other end of the housing 2. One end of the inlet port 3 passes through the side wall of the housing 2 and is located inside the housing 2. The annular stator 5 is installed inside the housing 2, and a rotating shaft is disposed within the annular stator 5. The rotating shaft is drively connected to the annular stator 5, with one end inserted into the inner surface of the end cap 1 and the other end extending out of the housing 2. A rotor is mounted on the outer side of the rotating shaft. The first mounting piece 8 is mounted on one end of the annular stator 5, and a second mounting piece 6 is also mounted on one end of the annular stator 5. The second mounting piece 6 and the first mounting piece 8 are positioned between the annular stator 5 and the end cap 1. Several connectors 7 are inserted into the first mounting piece 8 at one end. The extension plates 4 are used to connect the entire structure to other structures, and the two mounting pieces are fixed to the side wall of the annular stator 5.

[0048] In a specific embodiment, such as Figures 3-4 The connector 7 includes a limiting protrusion 71, an annular plate 72, a connecting plate 73, an extension plate 74, a wire pressing rod 75, a protruding plate 76, and a limiting block 77. The connecting plate 73 is connected to the annular plate 72 at both ends. A limiting block 77 is provided at the top of one end of the annular plate 72. The protruding plate 76 is installed on the surface of the connecting plate 73 and faces the limiting block 77. The wire pressing rod 75 is installed on the top of the connecting plate 73. Several extension plates 74 are installed at the bottom of the wire pressing rod 75, and several limiting protrusions 71 are installed on the inner wall of the wire pressing rod 75. The material used for connector 7 is similar to that of commonly used connectors, possessing conductivity. However, unlike conventional connectors, connector 7 has a certain degree of elasticity and can deform. When the insert plate 85 is placed between the connecting plate 73 and one end of the annular plate 72, the annular plate 72 will deform outward under the pressure of the protruding plate 76. Under the action of its own elastic force after deformation, it cooperates with the protruding plate 76 to press the insert plate 85, causing connector 7 to be clamped in the first mounting part 8. The outward deformation of the annular plate 72 will also cause the outer arc surface to abut against the inner wall of the rectangular limiting frame 84, completing secondary limiting. The wire will be placed on the wire pressing rod 7. In section 5, the wire is clamped by the limiting protrusion 71, and the electrical energy is transferred by the conductivity of the pressure rod 75 itself, so that the current enters the ring stator 5 through the plug plate 85. The connector 7 itself is a conductor, but its material and characteristics will reduce the amount of current entering, which can prevent the ring stator 5 from burning out. The general motor is a three-phase asynchronous motor, so it is equipped with three connectors 7. When the end cover 1 is placed on the outer shell 2, the inner wall of the end cover 1 will press the connector 7 to prevent the connector 7 from dislodging, and at the same time prevent cross-current. The limiting block 77 is set to limit the insertion depth of the connector 7 to prevent the problem of difficult removal.

[0049] In a specific embodiment, such as Figure 5The annular plate 72 also has a semi-annular inner groove 78 at one end of its upper part, and the limiting block 77 is set above the semi-annular inner groove 78. The top side wall of the insert plate 85 can also be provided with an annular protrusion, which can be locked in the semi-annular inner groove 78 to better limit the installation of the connector 7 and prevent it from easily falling off without human intervention.

[0050] In a specific embodiment, such as Figures 6-7 The first mounting component 8 includes a first mounting plate 81, a connector 82, a circular plate 83, a rectangular limiting frame 84, and an insert plate 85. The first mounting plate 81 is mounted on the end of the annular stator 5. The first mounting plate 81 has several circular holes. A portion of these holes house the connector 82, and several circular plates 83 are installed in the remaining holes. The rectangular limiting frame 84 is mounted on the top of each circular plate 83. The insert plate 85 is mounted on the top of the circular plate 83 and is positioned inside the rectangular limiting frame 84. The insert plate 85 is inserted between the protruding plate 76 and the annular plate 72. The first mounting plate 81 is fixed to the end face of the annular stator 5. Then, the connector 82 and the circular plate 83 are installed using the circular holes. The connector 82 and the circular plate 83 are used to electrically connect the conductive components to the annular stator 5.

[0051] In a specific embodiment, such as Figure 8 The second mounting component 6 includes a second mounting plate 61 and power cord sockets 62. The second mounting plate 61 is mounted on the end of the annular stator 5, and a plurality of power cord sockets 62 are formed on the second mounting plate 61. The power cord sockets 62 are used to expose the conductive metal part of the annular stator 5, and electrical connection is achieved after inserting wires.

[0052] In a specific embodiment, such as Figure 9 The inlet port 3 includes a lower connecting plate 31, placement holes 32, a limiting block 33, and an upper connecting plate 34. The lower connecting plate 31 has several placement holes 32 at its top, and the upper connecting plate 34 has a limiting block 33 on its bottom surface. The bottom of the limiting block 33 is positioned within the placement holes 32. One end of the lower connecting plate 31 and the upper connecting plate 34 passes through the side wall of the housing 2 and is located inside the housing 2. The placement holes 32 are used for the passage of wires, and the limiting blocks 33 cooperate with the placement holes 32 to clamp the wires and prevent them from moving.

[0053] In a specific embodiment, such as Figure 10 The outer casing 2 has a placement plate 21 on one end surface, and the annular stator 5 is placed on the placement plate 21. A through hole 22 is opened in the center of the placement plate 21, through which the rotating shaft passes. A rectangular hole is opened on the side wall of the outer casing 2, through which one end of the inlet port 3 passes. The through hole 22 is used for the rotating shaft to pass through, while the rectangular hole is used for installing and fixing the inlet port 3.

[0054] In a specific embodiment, such as Figure 10The extension plate 4 has connection holes at its outer end. The entire structure is screwed and fixed in various positions through the connection holes.

[0055] In one specific embodiment, connector 7 is made of a flexible material.

[0056] In use, the annular stator 5 is first installed in the housing 2, with one end of the annular stator 5 resting on the inner wall of the placement plate 21. Simultaneously, an interference fit is made between the outer side of the annular stator 5 and the inner surface of the housing 2 to fix the annular stator 5. After connecting the annular stator 5, the rotor is attached to the rotating shaft, and then one end of the rotating shaft is inserted into the end cover 1. Preferably, a bearing is installed at the shaft insertion position on the end cover 1, so that the rotation of the rotating shaft itself is not affected when it is inserted into the end cover 1. After assembling the rotating shaft, the connector 7 is attached... One end of the connecting plate 73 and the annular plate 72 is inserted into the rectangular limiting frame 84. The insert plate 85 is inserted between the annular plate 72 and the connecting plate 73. Because the connecting plate 73 will not deform, the distance between the flipped end of the annular plate 72 and the connecting plate 73 is limited. A protruding plate 76 is also provided on the connecting plate 73, which abuts against the side wall of the insert plate 85. Since the width of the insert plate 85 is greater than the distance between the flipped end of the annular plate 72 and the connecting plate 73, the connection plate 85 is positioned between the connecting plate 73 and the connecting plate 74. With the connector plate 73 stationary, the other end of the insert plate 85 will press the annular plate 72 outward. Since the annular plate 72 itself is made of a material with a certain elasticity, it uses its own elasticity to press and cooperate with the protruding plate 76 to clamp the insert plate 85. The outwardly moving part will abut against the inner wall of the rectangular limiting frame 84, completing the installation limiting of the connector 7. After the connector 7 is installed, since the first mounting part 8 and the second mounting part 6 are fixed on the end face of the annular stator 5, the external wire is inserted from the inlet port 3. A part of the wire is inserted into the connector 7 and fixed through the connector 7 to conduct electricity. The other part of the wire goes into the power cord socket 62 and connects with the annular stator 5 to form a circuit. After connecting the wires, the other end of the shaft is inserted into the housing 2. The final end will pass out from the through hole 22. The end cover 1 will also cover the opening end of the housing 2 to complete the installation of the entire motor. After power is applied, the stator generates a magnetic field to make the rotor carry the shaft to rotate, causing the shaft to generate rotational force.

[0057] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
