the utility model provides an outgoing line subassembly 1, including storage device 12 and the outgoing line 11 of being connected with motor stator, wherein:

the outgoing line 11 passes through the containing device; that is, both ends of the lead wires 11 extend out of the storage device, and at least part of the lead wires 11 are located in the storage device;

a rotating portion is present in the storage device 12, and the rotating portion can rotate under the action of external force to wind at least part of the outgoing line 11 on the rotating portion or release the outgoing line 11 wound on the rotating portion, so as to adjust the length of the outgoing line 11 extending out of the storage device.

Specifically, referring to fig. 2, the leading-out wire assembly 1 passes through one end of the receiving device to be connected with the motor stator, specifically, the stator copper wire coil 104, and the other end extends out of the receiving device to serve as a terminal. In the present embodiment, as shown in fig. 3, the lead wire height H1 is adjustable by enabling the lead wire 11 to be wound or released by rotation of the rotating portion, thereby adjusting the length of the lead wire 11 extending out of the housing device, in other words, the lead wire height H1 is adjustable when the lead wire assembly 1 is mounted in the compressor, thereby making the lead wire height H1 adaptable to different heat jacket heights H of the compressor.

As an alternative embodiment, referring to fig. 4, 5, 6, and 7, the housing 12 further includes a housing 121, the housing 121 has a cavity structure, two ends of the housing 121 include an upper end cover and a lower end cover, a housing cavity for accommodating the outgoing line 11 is formed on a side wall of the housing 121 and the two end covers, and openings for the outgoing line 11 to extend out are disposed on the two end covers of the housing 121.

As described with reference to fig. 4, the rotating part is disposed in the receiving cavity 123, and the portion of the outgoing line 11 located in the receiving cavity 123 is at least partially wound around the rotating part.

The storage device with the structure can store and contain the outgoing line 11 through the storage cavity, and the length of the outgoing line 11 extending out of the shell 121 is adjusted through rotation of the rotating part in the storage cavity 123, so that the situation that the outgoing line 11 is too long to cause hidden danger of a compressor is prevented, and meanwhile the universality of the stator is improved.

The openings of the two end caps include an upper end cap opening 124 and a lower end cap opening 125, so that the outgoing line 11 can be wound or released in the case 121 in order to facilitate the rotation of the rotation portion, as shown in fig. 6 and 7, the openings of the two end caps are disposed on the same side of the rotation portion, and the outgoing line 11 is at least partially wound on the rotation portion.

When the lead-out wire 11 is initially assembled, the lead-out wire extends into the containing cavity 123 from the inside of the lower end cover opening 125, and extends out from the upper end cover opening 124 positioned on the same side after being wound at least for more than half a turn on the rotating part; the structure is convenient for winding the outgoing line 11 on the rotating part, and can prevent the problem that the outgoing line 11 is difficult to be rewound again through the rotation of the rotating part after the outgoing line 11 is completely released.

In order to enable the rotating part to rotate inside the housing 121 under the action of external force, as an alternative embodiment, as shown in fig. 5, 6 and 7, the rotating part is a rotating shaft 122, the rotating shaft 122 is connected with two ends of the housing 121 and is arranged to penetrate through an end cover of the housing 121, and the rotating shaft 122 can rotate relative to the housing 121 under the action of external force with an axis of the rotating shaft 122.

The rotating shaft 122 is movably connected to the housing 121, that is, under the action of an external force, the rotating shaft 122 can rotate along its axis under the support of the end caps at both ends. As shown in fig. 7, through holes for supporting the rotation of the rotation shaft 122 may be formed in the two end caps, a diameter of the portion of the rotation shaft 122 outside the receiving cavity is larger than that of the through holes, and the diameter of the portion of the rotation shaft 122 outside the receiving cavity is smaller than that of the through holes, so as to prevent the rotation shaft 122 from rotating out of the housing 121. The above structure enables both ends of the rotation shaft 122 to be acted on by an external force and to rotate along its own axis under the support of the end caps.

Wherein, the external force for rotating the rotating shaft refers to: when the outgoing line 11 wound on the rotating shaft 122 needs to be released, that is, when the length of the outgoing line 11 extending out of the storage device is increased, the external outgoing line 11 can be pulled, and the acting force of the outgoing line 11 on the rotating shaft 122 drives the rotating part to rotate along the axis of the rotating part in the housing 121; when it is necessary to wind the lead-out wires 11 around the rotary shaft 122, that is, to reduce the length of the lead-out wires 11 protruding out of the housing device, the rotary shaft 122 may be manually rotated to rotate with respect to the housing 121 and rewind the lead-out wires 11 around the rotary shaft 122. Wherein the rotation direction of the rotation shaft 122 when releasing the lead-out wires 11 is opposite to that when winding the lead-out wires 11.

Both ends of the rotary shaft 122 are disposed through the end caps of the housing 121 to facilitate manual rotation of the rotary shaft 122.

It should be understood that since the length of the outlet wire is determined when the outlet wire is fitted to the compressor, the length of the outlet wire does not need to be changed after installation, in other words, the length of the outlet wire does not need to be adjusted for the same type of compressor, and thus, the length of the outlet wire extending out of the storage device is adjusted by pulling the outlet wire or manually winding the rotary shaft 122, and thus, the length of the outlet wire does not need to be adjusted again.

Therefore, the lead wire can be completely adapted to the installation situation of the compressor by manually winding the lead wire, and the lead wire can be rewound without a more complicated structure.

As an alternative embodiment, referring to fig. 6 and 7, the rotation shaft 122 is disposed in a collinear manner with the central axis of the housing 121. The above-described structure facilitates more smooth rotation of the rotary shaft 122 within the housing 121.

A clamping space for clamping the lead wires 11 is formed between the locking buckle 141 and the baffle 142, and the range of the clamping space is adjustable. When the outgoing line 11 needs to be fixed, the distance between the locking buckle 141 and the baffle 142 can be adjusted to be matched with the diameter of the outgoing line 11, and the outgoing line 11 can be fixed on the premise of not damaging the outgoing line 11 in a mode that the outgoing line 11 is clamped by the locking buckle 141 and the baffle 142.
