The present utility model proposes a three-phase plastic-coated structure 100 for a motor, which aims to prolong the transmission path of welding heat so as to improve the problems of scorching and even melting of plastic parts 10 and ensure the quality of products.
The following will describe the specific structure of the three-phase plastic coated structure 100 for a motor according to the present utility model:
Referring to fig. 1 to 5 in combination, in an embodiment of a three-phase plastic-coated structure 100 for a motor according to the present utility model, the three-phase plastic-coated structure 100 for a motor includes a plastic part 10 and a three-phase copper bar 20; the plastic part 10 is provided with at least three mounting holes 11 which are arranged at intervals; the three-phase copper bars 20 are integrated on the plastic part 10, copper bars 21 of any phase of the three-phase copper bars 20 are positioned in corresponding mounting holes 11, and the mounting holes 11 are used for guiding stator outgoing lines 310 of the motor to be attached to one side of the copper bars 21; the plastic part 10 is provided with a sinking structure 12 at a position close to the copper bar 21.
It can be understood that in the three-phase plastic-coated structure 100 for a motor provided by the utility model, any phase copper bar 21 of the three-phase copper bar 20 is positioned in the corresponding mounting hole 11, the mounting hole 11 of the plastic part 10 is used for guiding the stator outgoing line 310 of the motor to be attached to one side of the copper bar 21, so that each phase copper bar 21 is used for realizing welding positioning with one stator outgoing line 310; in addition, through being provided with the structure 12 that sinks in the position that plastic part 10 is close to copper bar 21, like this, can prolong the distance of welding point 2000 and plastic part 10 of copper bar 21 through the setting of structure 12 that sinks, and then lengthen the transfer path of welding heat to improve the burnt even melting problem of plastic part 10, in order to guarantee product quality.
In this embodiment, when the three-phase plastic coating structure 100 for a motor is applied to the stator assembly 1000, the three-phase stator lead wires 310 of the stator winding are respectively inserted into the three mounting holes 11, and each phase of stator lead wire 310 is close to one copper bar 21, at this time, the ends of each phase of stator lead wire 310 and one phase of copper bar 21 can be welded, so that a welding point 2000 is formed at the ends of each phase of stator lead wire 310 and one phase of copper bar 21, and the welding positioning of the three-phase copper bar 21 and the three-phase stator lead wire 310 can be realized.
It should be noted that, specifically, argon arc welding, laser welding or other welding methods may be used to realize the welding positioning of the three-phase copper bar 21 and the three-phase stator lead wire 310.
In some embodiments, the three-phase copper bar 20 may further include three-phase lead-out terminals 22, each phase lead-out terminal 22 is electrically connected to one phase copper bar 21, and the three-phase lead-out terminals 22 are used to electrically connect to an external frequency converter or the like.
In the practical application process, one or at least two phase stator lead wires 310 may be provided, and correspondingly, one or at least two phase copper bars 21 may be provided, which may be specific according to the actual use situation, and are not limited herein.
In the practical application process, the three-phase copper bar 20 and the plastic part 10 can be in an integrally formed structure, and of course, the three-phase copper bar 20 can also be fixed on the plastic part 10 by adopting modes of bonding, clamping, screw connection and the like so as to be integrated with the plastic part 10.
It should be noted that, the sinking structure 12 of the plastic part 10 may be a groove, so the deeper the groove, the longer the distance between the welding point 2000 of the copper bar 21 and the plastic part 10, and the longer the welding heat transfer path.
Further, referring to fig. 3 and 5 in combination, in an embodiment of the three-phase plastic-coated structure 100 for an electric motor according to the present utility model, the sinking structure 12 is located at the back of the side where the copper bar 21 is attached to the stator lead-out wire 310.
By arranging the sinking structure 12 on the back of one side, attached to the copper bar 21 and the stator outgoing line 310, the distance between the welding point 2000 of the copper bar 21 and the plastic part 10 can be effectively prolonged, interference between the sinking structure 12 and the mounting hole 11 can be avoided, and the welding positioning of the copper bar 21 and the stator outgoing line 310 is realized, and meanwhile, the transmission path of welding heat is effectively prolonged, so that the problem of burning and even melting of the plastic part 10 is solved.

In the practical application process, the sinking structure 12 may extend along the width direction of the copper bar 21, or may extend along the circumferential direction of the copper bar 21.
Because the conventional stator lead-out wire 310 is required to be manually shaped and clamped with the copper bar 21 by using the clamp, and then welded, the manual shaping and clamping are required in the welding process, resulting in low welding efficiency.

Further, referring to fig. 3 and 5 in combination, in an embodiment of the three-phase plastic coated structure 100 for a motor according to the present utility model, the penetrating end 11a of the mounting hole 11 is provided with a chamfer 112.

Further, referring to fig. 3 and 5 in combination, in an embodiment of the three-phase plastic coated structure 100 for an electric motor according to the present utility model, each of the mounting slots 13 is in communication with one of the mounting holes 11.
After the stator lead-out wire 310 is mounted to the mounting hole 11, the stator lead-out wire 310 and the copper bar 21 can be attached together, so that the welding end of the copper bar 21 and the welding end of the stator lead-out wire 310 are close to each other, the stator lead-out wire 310 and the copper bar 21 can be clamped without tools such as clamps, and the welding positioning of the stator lead-out wire 310 and the copper bar 21 can be well realized.
Further, referring to fig. 1 to 3 in combination, in an embodiment of a three-phase plastic-coated structure 100 for a motor according to the present utility model, a plastic part 10 and a three-phase copper bar 20 are integrally formed. By this arrangement, the mounting reliability of the three-phase copper bar 20 can be further improved.
It should be noted that, since the materials of the plastic part 10 and the three-phase copper bar 20 are inconsistent, the three-phase copper bar 20 can be molded first, then the three-phase copper bar 20 is placed in a mold, and injection molding is performed in the mold, so that the plastic part and the three-phase copper bar 20 can be molded into an integral structure.
