In this embodiment, the number of the second protruding portions 3226 is two, the second protruding portions 3226 are respectively disposed on two sides of the first protruding portion 3224, and are fixedly connected to the first protruding portion 3224, wherein the first protruding portion 3224 and the two second protruding portions 3226 are integrally formed, so as to ensure the structural strength of the position-limiting portion 322. Specifically, the two second protrusions 3226 are symmetrically disposed on two sides of the first protrusion 3224 along the center line of the limiting portion body 3222, that is, two limiting grooves 3228 symmetric along the center line of the limiting portion body 3222 are formed between the two second protrusions 3226 and the first protrusion 3224, respectively, and the connecting portion 262 is sleeved on the first protrusion 3224 and clamped in the limiting grooves 3228, so that the outgoing line 26 can be detachably connected to the connection terminal 32, the connecting portion 262 of the outgoing line 26 can be limited in the up-down direction, the connection strength between the outgoing line 26 and the connection terminal 32 is further improved, and the situation that the outgoing line 26 falls off from the connection terminal 32 in the vibration process of the compressor can be effectively reduced. Meanwhile, the connection part 262 is in the process of being matched with the limit part 322, the whole limit part 322 can be stressed uniformly, the situation that in the process of generating vibration during the operation of the compressor, the limit part 322 is locally broken due to uneven stress is avoided, the outgoing line 26 is led to fall off from the wiring terminal 32, and the stability during the operation of the compressor device is further improved.

It should be noted that, since the position-limiting groove 3228 can be formed between the first protruding portion 3224 and the second protruding portion 3226, by providing two second protruding portions 3226, the position-limiting groove 3228 can be formed between adjacent first protruding portion 3224 and second protruding portion 3226, that is, two position-limiting grooves 3228 symmetrical along the central line of the position-limiting portion body 3222 can be formed between the first protruding portion 3224 and the second protruding portion 3226, and by providing the second protruding portion 3226 and the position-limiting groove 3228, the connecting portion 262 can be limited, especially, the connecting portion 262 can be limited in the up-down direction, so that the connection reliability between the outgoing line 26 and the connection terminal 32 is improved.

That is, by limiting the lengths of the first and second protruding portions 3224 and 3226, the structural strength of the first and second protruding portions 3224 and 3226 can be ensured while the connecting portion 262 and the position-limiting portion 322 are effectively engaged. Specifically, the second protrusion 3226 is connected to the connection portion 262 along the edgeThe length in the connecting direction is not longer, and if the length is longer, the structural strength of the second protruding portion 3226 is reduced, in the process that the first protruding portion 3224 is matched with the connecting portion 262, the second protruding portion 3226 is prone to being broken due to vertical vibration of the compressor, the length of the second protruding portion 3226 in the direction connected with the connecting portion 262 is not too short, and if the length is too short, in the process that the connecting portion 262 is matched with the first protruding portion 3224, it cannot be guaranteed that the second protruding portion 3226 can effectively limit the connecting portion 262 in the direction perpendicular to the central line of the limiting portion body 3222, and therefore in the operation process of the compressor, the outgoing line 26 is prone to falling off from the wiring terminal 32 due to vibration, so that the motor assembly 2 is phase-missing or even burnt, and safety and reliability in the operation of the compressor are effectively improved. In addition, the length of the first protruding portion 3224 in the direction connecting with the connecting portion 262 should not be too long, if the length is too long, in order to ensure effective matching between the connecting portion 262 and the first protruding portion 3224, the size of the connecting portion 262 needs to be increased correspondingly, so as to improve the production cost of the compressor, and the structural strength of the compressor is reduced due to the too long first protruding portion 3224. If the length is too short, the effective insertion between the connecting portion 262 and the first protruding portion 3224 cannot be ensured, and the reliability of the engagement between the limiting portion 322 and the connecting portion 262 is further reduced. Therefore, by making L1 and L2 satisfy the above relationship, it is possible to ensure the structural strength of the first and second protruding portions 3224 and 3226 while ensuring the effective engagement of the stopper portion 322 with the connecting portion 262, and further improve the safety and reliability of the compressor in operation.
