An outlet assembly 100 for an electric machine, such as a flat wire electric machine or other ac electric machine, according to an embodiment of the present utility model is illustrated with reference to fig. 1-4, the outlet assembly 100 being used to draw a stator winding 200 in the electric machine so that the stator winding 200 is electrically connected to an external device, such as an ac power source. The pinout assembly 100 includes a first pinout 110, a second pinout 120, and a third pinout 130.

The first outgoing line 110 includes a first core and a first insulating layer surrounding the first core. The first lead wire 110 may be a circular wire, that is, the first core may have a circular cross-sectional shape in the extending direction thereof. The first insulating layer may be an insulating paint film or a plastic film wrapping the circumferential surface of the first core. A first end of the first outgoing line 110 exposes a first core of a first preset length to form a first welding portion 1111, and the first welding portion 1111 is used for welding with the stator winding 200. The first predetermined length may be 8-10mm or other suitable length. Here, the exposure means that the circumferential surface of the core has no insulating layer. The second end of the first lead-out wire 110 exposes a first core of a second preset length, the first core exposed at the second end of the first lead-out wire 110 is bent by a first preset angle to form a second welding portion 1151, where the bent first preset angle refers to that the first core exposed at the second end of the first lead-out wire 110 is bent from a position near the middle to form two sections, and the two sections formed after bending are in the first preset angle (that is, one section of the bending is deflected by the first preset angle from a position before bending to a position after bending). The second preset length may be 16-20mm (i.e., about 8-10mm for each segment after bending) or other suitable length, and the first preset angle may be 180 ° or other suitable angle. The second weld 1151 is used to weld directly to an external device or to other components in the pinout assembly 100. Since the second welding portion 1151 is formed by bending the exposed first wire core by a first predetermined angle, the second welding portion 1151 has a larger welding area than the wire core which is not bent, and can be welded more firmly with external devices or with other components in the lead out assembly 100. In addition, when the first preset angle is 180 degrees, two sections formed after the first wire core exposed at the second end of the first outgoing line 110 is bent are parallel to each other, and the welding mode of each section can be the same as that of a conventional wire core which is not bent, so that the welding equipment and the welding process parameters can be adjusted, the welding process is stable, and the method is suitable for mass production. In other embodiments, the first end of the first outgoing line 110 exposing the first core may also be bent at a first predetermined angle to form a first welding portion, so as to increase the welding area of the first welding portion, and enable the first welding portion to be welded with the stator winding 200 more firmly.

The second outgoing line 120 includes a second core and a second insulating layer wrapping the second core. The second outgoing line 120 may be a circular wire, that is, the second wire core may have a circular cross-sectional shape in the extending direction thereof. The second insulating layer may be an insulating paint film or a plastic film wrapping the circumferential surface of the second core. The first end of the second lead wire 120 exposes a second core of a third preset length to form a third welding portion 1211, and the third welding portion 1211 is used for welding with the stator winding 200. The third predetermined length may be 8-10mm or other suitable length. The second end of the second lead wire 120 exposes a second core of a fourth preset length, and the second core exposed at the second end of the second lead wire 120 is bent by a second preset angle to form a fourth welded portion 1251, where the bent second preset angle refers to bending the second core exposed at the second end of the second lead wire 120 from a position near the middle to form two sections, where the two sections formed after bending are at the second preset angle (that is, one section of bending is deflected by the second preset angle from a position before bending to a position after bending). The fourth predetermined length may be 16-20mm (i.e., about 8-10mm for each segment after bending) or other suitable length, and the second predetermined angle may be 180 ° or other suitable angle. The fourth solder 1251 is used for soldering directly to an external device or to other components in the outlet assembly 100. Since the fourth welded portion 1251 is formed by bending the exposed second wire core by the second predetermined angle, the fourth welded portion 1251 has a larger welding area than the wire core which is not bent, and can be welded more firmly to an external device or to other components in the lead out assembly 100. In addition, when the second preset angle is 180 degrees, two sections formed after the second wire core exposed at the second end of the second outgoing line 120 is bent are parallel to each other, and the welding mode of each section can be the same as that of a conventional wire core which is not bent, so that the welding equipment and the welding process parameters can be adjusted, the welding process is stable, and the welding device is suitable for mass production. In other embodiments, the second core exposed from the first end of the second lead wire 120 may also be bent at a second predetermined angle to form a third welding portion, so as to increase the welding area between the third welding portion and the stator winding 200, and enable the third welding portion to be welded with the stator winding 200 more firmly.

The third outgoing line 130 includes a third wire core and a third insulating layer wrapping the third wire core. The third outgoing line 130 may be a circular wire, that is, the cross-sectional shape of the third wire core in the extending direction thereof may be circular. The second insulating layer may be an insulating paint film or a plastic film wrapping the circumferential surface of the third wire core. The first end of the third outgoing line 130 exposes a third core of a fifth preset length to form a fifth welding portion 1311, and the fifth welding portion 1311 is for welding with the stator winding 200. The fifth predetermined length may be 8-10mm or other suitable length. The second end of the third lead wire 130 exposes a third core of a sixth preset length, the third core exposed at the second end of the third lead wire 130 is bent by a third preset angle to form a sixth welded portion 1351, where the bent third preset angle refers to that the third core exposed at the second end of the third lead wire 130 is bent from a position in the middle to a position close to the middle to form two sections, and the two sections formed after bending are in the third preset angle (that is, one section of the bending is deflected by the third preset angle from the position before bending to the position after bending). The sixth preset length may be 16-20mm (i.e., about 8-10mm for each segment after bending) or other suitable length, and the third preset angle may be 180 ° or other suitable angle. The sixth weld 1351 is used to weld directly to external equipment or to other components in the pinout assembly 100. Since the sixth welding portion 1351 is formed by bending the exposed third wire core by the third predetermined angle, the sixth welding portion 1351 has a larger welding area than the wire core that is not bent, and can be welded more firmly with external equipment or with other components in the lead out assembly 100. In addition, when the third preset angle is 180 degrees, two sections formed after the third wire core exposed from the second end of the third outgoing line 130 is bent are parallel to each other, and the welding mode of each section can be the same as that of the conventional wire core which is not bent, so that the welding equipment and the welding process parameters can be not adjusted, the welding process is stable, and the welding device is suitable for mass production. In other embodiments, the third core exposed from the first end of the third outgoing line 130 may also be bent at a third predetermined angle to form a fifth welding portion, so as to increase the welding area between the fifth welding portion and the stator winding 200, and enable the welding between the fifth welding portion and the stator winding 200 to be more firmly performed.

Further, referring to fig. 3 and 4, in the embodiment of the present utility model, the first outgoing line 110 includes a first connection section 111, a first middle section 113, a second connection section 115, a first bending section 112 between the first connection section 111 and the first middle section 113, and a second bending section 114 between the first middle section 113 and the second connection section 115, wherein a first welding portion 1111 is located at the first connection section 111, and a second welding portion 1151 is located at the second connection section 115. By providing the first bending section 112 and the second bending section 114, the first weld 1111 and the second weld 1151 may be positioned differently with respect to the stator winding 200 to better draw out the stator winding 200. Specifically, in the present embodiment, the first connection section 111 extends entirely along the axial direction of the stator winding 200 (or approximately along the axial direction of the stator winding 200), the first intermediate section 113 extends along the circumferential direction of the stator winding 200, and the second connection section 115 extends entirely along the radial direction of the stator winding 200 (or approximately along the radial direction of the stator winding 200), so that the radial space of the motor can be fully utilized, the axial space of the motor is not occupied, the materials used for the motor housing and the rotating shaft can be effectively reduced, and the motor cost can be reduced. And since the first lead wire 110 is a circular lead wire, bending can be more conveniently performed. Similar to the first lead wire 110, the second lead wire 120 includes a third connecting section 121, a second intermediate section 123, a fourth connecting section 125, a third bent section 122 between the third connecting section 121 and the second intermediate section 123, and a fourth bent section 124 between the second intermediate section 123 and the fourth connecting section 125, wherein a third welded portion 1211 is located at the third connecting section 121, and a fourth welded portion 1251 is located at the fourth connecting section 125.

Specifically, the stator winding 200 includes U-phase, V-phase and W-phase windings, and the first welding portion 1111, the second welding portion 1151 and the third welding portion 1211 in the first, third and fifth connection sections 111, 121 and 131 are used to weld with the U-phase, V-phase and W-phase windings, respectively. The first middle section 113, the second middle section 123 and the third middle section 133 are sequentially arranged at intervals along the axial direction of the stator winding 200 of the motor, so that space occupation in the motor is saved, and mutual influence among outgoing lines is avoided.
