As shown in fig. 3 to 5, the first wiring structure 20 includes a first wiring structure body 21 and a fixing portion 23 which are integrally formed.
The first wiring structure body 21 is substantially a cubic structure, and includes a first upper surface, a first lower surface, a first front surface, a first rear surface, a first right surface, and a first left surface.

In the first direction, the fixing portion 23 is located at one end of the wiring space 212 close to the first lower surface, and the bottom wall of the fixing portion 23 is flush with the first lower surface of the first wiring structure body 21. In the second direction, the fixing portion 23 is located on a side of the wiring space 212 close to the first rear surface, and a gap exists between a side wall of the fixing portion 23 and the first wiring structure body 21 to cooperate with the first wiring structure 20.
The post 40 is a cylindrical structure formed by a metal material with good electrical conductivity, one end of the post 40 is fixed to one end of the fixing portion 23 away from the first lower surface, the other end of the post 40 faces a direction away from the fixing portion 23, a central axis of the post 40 is parallel to the first direction, and the fixing portion 23 is located in front of the post 40 in an inserting direction of the wire connecting portion 63.
In this way, the terminal 40 is fixed in the wiring space 212 of the first wiring structure 20, and the terminal of the stator lead-out wire and the terminal of the power line can be respectively sleeved on the terminal 40 to realize electrical connection.
Further, in some embodiments, the side of the fixing portion 23, which is away from the first rear surface, where the end of the fixing portion 40 is connected to the terminal post has a mating surface 232, the mating surface 232 is shaped to match the arc-shaped structure of the power line, and the power line can be tightly attached to the mating surface 232, so that the gap between the power line and the terminal box 100 is minimized.
Specifically, the mating face 232 is a substantially circular arc face, the mating face 232 extends in a curved manner from a side close to the terminal 40 to a side away from the terminal 40, and a distance of the mating face 232 from the terminal 40 in the first direction gradually increases to match a shape of the power line. It will be appreciated that the shape of the mating surface 232 is not so limited and may be configured to meet different needs depending on the shape of the power line.
Further in some embodiments, the lead-out groove 234 is opened on a side of the fixing portion 23 away from the first rear surface, an extending direction of the lead-out groove 234 is parallel to the first direction and communicates the mating surface 232 with a bottom wall of the fixing portion 23, and a cross-sectional shape of the lead-out groove 234 matches a shape of the stator lead-out wire. Thus, the stator lead portion is retained in the lead groove 234 and extends out of the terminal box 100.
As shown in fig. 6 and 7, the second wiring structure 60 includes a connection portion 61 and three wiring portions 63, the connection portion 61 has a plate-shaped structure with a rectangular cross section, the length direction of the connection portion 61 extends in the third direction, the width direction of the connection portion 61 extends in the second direction, and the thickness direction of the connection portion 61 extends in the third direction.
The three wire connecting portions 63 are each protruded from one side of the connecting portion 61 in the first direction and located on one side of the connecting portion 61 in the second direction. The three wire connection portions 63 are arranged at intervals in the third direction, one end of each wire connection portion 61 is connected to the connection portion 61, the other end of each wire connection portion 63 extends in the first direction away from the connection portion 61, and the shape of each wire connection portion 63 matches the shape of the wire connection space 212. It is to be understood that the number of the wire connecting portions 63 is not limited thereto, and may be set as needed to satisfy different requirements.
Thus, each of the wire connection portions 63 is provided corresponding to one of the wire connection spaces 212 on the first wiring structure body 21. When the first wiring structure 20 and the second wiring structure 60 are nested with each other, the connecting portion 61 completely covers the first upper surface of the first wiring structure main body 21, and the three wiring portions 63 are respectively inserted into the three wiring spaces 212. Preferably, the connecting portion 61 and the first wiring structure 20 are both provided with fixing holes, so that the connecting portion can be detachably connected by a fastener, thereby integrally connecting the first wiring structure 20 and the second wiring structure 60.
Further, the wire connection hole 632 is opened at an end surface of the wire connection portion 63 on a side away from the connection portion 61, and a central axis of the wire connection hole 632 extends in the first direction. Specifically, the wiring hole 632 includes a wiring segment 6321 and a sealing segment 6323 that communicate with each other, the cross section of the wiring segment 6321 is substantially circular to match the shape of the cross section of the post 40, and the cross section of the sealing segment 6323 is substantially rectangular to match the shape of the cross section of the fixing portion 23.
In this way, when the wiring portion 63 is inserted into the wiring space 212, the fixing portion 23 of the first wiring structure 20 is inserted into the sealing section 6323, so that the wiring terminal is located in the package of the wiring portion 63 to form a closed environment, and the wiring terminal 40 is inserted into the wiring section 6321 to ensure that the wiring terminal of the stator lead-out wire and the wiring terminal of the power line are electrically connected.

In this manner, the power wire can be conveniently threaded through the exit hole 634 to the sealing segment 6323 of the wire connection hole 632. Preferably, the shape of the cross section of the lead-out hole 634 is matched with the shape of the cross section of the power wire, so that the gap between the power wire and the hole wall of the lead-out hole 634 is reduced, and the occurrence of condensed water in the lead-out hole 634 is avoided.
In some embodiments, the first wiring structure 20 and the second wiring structure 60 are both made of insulating materials, and preferably, in an embodiment, the first wiring structure 20 and the second wiring structure 60 are both made of plastic, so that a good electrical insulation effect is achieved. It is understood that the materials of the first wiring structure 20 and the second wiring structure 60 are not limited thereto, and may be set as required to meet different requirements.
Above-mentioned terminal box 100 is formed through first wiring structure 20 and the mutual nestification of second wiring structure 60, and first wiring structure 20 extrudes the air between the two with second wiring structure 60 in the assembling process, and the clearance between first wiring structure 20 and the second wiring structure 60 is very little to showing the inside air content of terminal box 100 that has reduced, thereby effectively avoiding the production of comdenstion water. Moreover, the power line is connected with the binding post 40 through the leading-out hole 634, and the shape of the leading-out hole 634 is matched with that of the power line, so that air in the leading-out hole 634 is effectively prevented, further, condensate water is prevented from being generated in the leading-out hole 634, and finally, the reliability and the safety of long-term operation of the motor are guaranteed.
