[0043] like Figure 1 As shown, the motor further includes a connector 600 , and the motor lead 200 is connected to the connector 600 .
[0044] like Figure 2 and Figure 3 As shown, a plug-in accommodating cavity 13 communicating with the clamping cavity 12 is provided in the fixed shell 1, and the plug-in accommodating cavity 13 can accommodate the plug-in portion 23. The arrangement of the plug-in accommodating cavity 13 allows the plug-in portion 23 to be limited in the plug-in accommodating cavity 13 to prevent the connecting terminal 2 from moving left and right.
[0045] Specifically, the upper end surface of the plug-in portion 23 can be pressed against the protrusion 11 to prevent the connecting terminal 2 from moving upward, thereby ensuring a stable connection between the plug-in portion 23 and the motor pin 300 .

[0050] Furthermore, the spacing between any two adjacent connection terminals 2 is not equal, so that the spacing between any two adjacent motor leads 200 is also not equal, and the spacing between any two adjacent motor pins 300 is also not equal, which makes it less likely for the wiring sequence to be wrong, thereby achieving the purpose of fool-proofing and facilitating installation.
[0051] Furthermore, the fixed shell 1 is provided with a lead hole 17, and the motor lead 200 extends into the lead hole 17 and is crimped on the crimping portion 24.

[0057] Furthermore, a first card slot 121 is provided on the first shell 15, and a second card slot 122 is provided on the second shell 16. When the first shell 15 and the second shell 16 are installed, the first card slot 121 and the second card slot 122 form the above-mentioned card connection cavity 12, so that the connecting base 22 can be carded into the card connection cavity 12, thereby preventing the connecting terminal 2 from moving left and right in the fixed shell 1, thereby ensuring the connection stability between the connecting terminal 2 and the motor lead 200, and also ensuring the connection stability between the connecting terminal 2 and the motor pin 300.

[0059] Furthermore, a first crimping cavity 141 is formed on the first shell 15 , and a second crimping cavity 142 is formed on the second shell 16 . When the first shell 15 and the second shell 16 are installed, the first crimping cavity 141 and the second crimping cavity 142 form the crimping accommodating cavity 14 to accommodate the crimping portion 24 .
[0060] Furthermore, a first guide groove 171 is formed on the first shell 15, and a second guide groove 172 is formed on the second shell 16. When the first shell 15 and the second shell 16 are installed, the first guide groove 171 and the second guide groove 172 form the above-mentioned lead hole 17 so that the motor lead 200 passes through the fixed shell 1 and is connected to the connector 600.
[0061] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model.
