[0076] The limiting column portion of the present invention preferably includes a protrusion, which is arranged at the bottom end of the wire fixing device and connects the three steps of the bottom surface.

[0085] The present invention can match the terminal posts and facilitate wiring through the arrangement of the terminal post channels, that is, the interface at the end (connecting the power supply and the motor). At the same time, the arrangement of the terminal post channel holes is also related to the position of the lead-out wires.

The terminal channel 7 passes through from one circumferential side surface of the wire fixing body 1 to the other circumferential side surface, and the terminal channel 7 is connected with the terminal channel 6 inside the wire fixing body 1.

[0088] The present invention can accommodate the terminal through the terminal channel which is arranged from one circumferential side surface of the fixed wire body to the other circumferential side surface, and the terminal channel is connected with the terminal post channel, so that wiring can be formed between the terminal posts to ensure effective wiring of the motor. The wiring is done from the inside without the need for complicated winding from the outside, which further reduces the volume occupied by disorderly winding, further reduces the space of the compressor, and further achieves weight reduction of the compressor.

[0089] In some embodiments,

The width of the second channel 72 along the axial direction of the motor is greater than the width of the first channel 71, and the height of the second channel 72 along the radial direction of the motor is less than the height of the first channel 71.

[0091] The present invention further achieves the effect of limiting the terminal position by configuring the terminal channel to be a first channel and a second channel structure with different widths and heights, thereby avoiding poor contact between the terminal and the terminal post.

[0092] In some embodiments,

[0093] The first channel 71 is connected to the second channel 72 inside the terminal channel 7, and a first step 9 in the direction of the height and a second step 10 in the direction of the width are formed at the connection, and the height b6 of the first step 9 is greater than 1 / 2 of the height of the terminal, and the width b5 of the second step 10 is 0.5 to 0.8 mm.

The width of the second step is b5, and the height of the first step is b6. The height of b6 is greater than 1 / 2 of the height of the terminal. The width of b5 is required to be 0.5-0.8 mm, in order to form a height difference with the first channel, and to use the height difference to block the front end of the terminal to prevent the terminal from falling out. The terminal enters from the first channel and stops at the first step. The terminal head fin is clamped by the second step, so that the terminal head stays at the intersection of the first channel and the second channel. The terminal is assembled with the terminal through the terminal channel.

[0095] In some embodiments,

[0096] The terminal channels 7 include three, and the three terminal channels 7 are arranged in sequence along the axial direction of the motor, and the terminal channels 7 are connected to the terminal post channels 6 in a one-to-one correspondence; between two adjacent terminal channels 7, the first channel 71 in one of the terminal channels 7 is connected to the circumferential end surface of one side of the fixed wire body 1, and the second channel 72 is connected to the circumferential end surface of the other side of the fixed wire body 1; the second channel 72 in the other terminal channel 7 is connected to the circumferential end surface of one side of the fixed wire body 1, and the first channel 71 is connected to the circumferential end surface of the other side of the fixed wire body 1.
