[0045] The connecting terminal according to an embodiment of the present application is described below with reference to the drawings.

[0046] The connecting terminal according to an embodiment of the present application is used for a motor and comprises a lead pin 23 and a lead terminal 1, wherein the motor can be a plastic-sealed brushless direct-current motor, specifically, as shown in Figure 1 、 Figure 7 and Figure 8 , the motor comprises a stator assembly 100, the stator assembly 100 comprises a stator component 2, the stator component 2 comprises a housing 21 and a winding 22, the winding 22 is arranged in the housing 21, the lead pin 23 is connected with the winding 22, at least part of the lead pin 23 is located outside the housing 21 for connection with the lead terminal 1, and the lead terminal 1 is used for connecting a lead wire 3.

[0047] As shown in Figure 2 and Figure 3 , in combination with Figure 9 and Figure 10 , the lead terminal 1 comprises a plug-in portion 11 and a connecting portion 12, the plug-in portion 11 has a plug-in slot 113, the lead pin 23 is adapted to be inserted into the plug-in slot 113 and is in interference fit with the plug-in portion 11, the connecting portion 12 is connected with the plug-in portion 11, and the connecting portion 12 is used for connecting the lead wire 3. The lead pin 23 is inserted into the plug-in slot 113 to realize the connection between the lead pin 23 and the lead terminal 1, thereby realizing the connection between the winding 22 and the lead wire 3, such as a power line.

[0048] In the present application, the lead terminal 1 is arranged, so that the lead wire 3 and the lead pin 23 are connected through the plug-in connection of the lead terminal 1 and the lead pin 23, the threading and welding operation of the lead wire 3 and the lead pin 23 can be avoided, the connection mode between the lead wire 3 and the lead pin 23 can be simplified, the operation is convenient, the connection efficiency is improved, and automatic production can be realized. In addition, the welding connection of the lead wire 3 and the lead pin 23 can be avoided, the quality risk of virtual welding and the friction noise problem caused by tin beads generated by welding can be avoided, and the experience of users is improved.

[0049] In addition, the lead pin 23 is in interference fit with the plug-in portion 11 in the plug-in slot 113, the reliability of the fixation of the lead pin 23 and the plug-in slot 113 can be improved, the lead terminal 1 can be prevented from being separated from the lead pin 23, the reliability of the connection between the lead terminal 1 and the lead pin 23 is ensured, and thus the reliability of the connection between the lead wire 3 and the winding 22 is ensured.

[0050] Further, as shown in Figure 8 、 Figure 9 、 Figure 10 and Figure 12 , in combination with Figure 4 and Figure 5The inner wall of the insertion slot 113 is provided with a limiting protrusion 114, and the limiting protrusion 114 is adapted to be located in the limiting hole 232. It can be understood that, after the lead terminal 1 and the lead pin 23 are assembled in place in an interference fit, the limiting protrusion 114 is just buckled in the limiting hole 232 of the lead pin 23. The cooperation of the limiting protrusion 114 and the limiting hole 232 makes the lead terminal 1 be locked on the lead pin 23, so that the lead terminal 1 can be directly and effectively buckled on the lead pin 23, the lead terminal 1 is effectively constrained in the insertion direction of the lead pin 23 and the insertion slot 113, the lead terminal 1 is prevented from being separated from the lead pin 23, and the reliability of the connection between the lead terminal 1 and the lead pin 23 is improved.

[0051] The connecting terminal according to the embodiment of the utility model can realize convenient connection between the lead 3 and the lead pin 23, avoid friction noise caused by tin beads generated by welding, and improve user experience. In addition, by arranging the limiting protrusion 114 on the inner wall of the insertion slot 113 and the limiting hole 232 on the lead pin 23, after the lead pin 23 is assembled in place in the insertion slot 113 in an interference fit, the limiting protrusion 114 is clamped in the limiting hole 232, the reliability of the connection between the lead terminal 1 and the lead pin 23 can be improved, and thus the reliability of the connection between the lead 3 and the winding 22 is improved.

[0052] In some embodiments of the utility model, as shown in Figure 9 and Figure 10 The insertion part 11 includes an insertion main body 111 and a curled edge 112, the insertion main body 111 is formed as a plate-shaped structure, the connecting part 12 is connected with the insertion main body 111, the curled edge 112 is arranged on one side of the insertion main body 111 in the thickness direction and the first end is connected with the insertion main body 111, the curled edge 112 is a curve type protruding in the direction away from the insertion main body 111 along the thickness direction of the insertion main body 111, the second end of the curled edge 112 and the insertion main body 111 define the insertion slot 113, and the first end and the second end are opposite ends of the curled edge 112. When the lead pin 23 is not inserted into the insertion slot 113, the distance between the second end of the curled edge 112 and the insertion main body 111 can be less than or equal to the thickness of the insertion part of the lead pin 23. Since the curled edge 112 is arranged to be curved, the curled edge 112 has elasticity, when the lead pin 23 is inserted into the insertion slot 113, the second end of the curled edge 112 can deform and move in the direction away from the insertion main body 111, so that the lead pin 23 is conveniently inserted into the insertion slot 113. After the lead pin 23 is inserted into the insertion slot 113, the second end of the curled edge 112 can abut against the lead pin 23, and the lead pin 23 can abut against the insertion main body 111, so as to realize the interference fit between the lead pin 23 and the insertion part 11, and ensure the reliability of the fixation and the electrical connection between the lead terminal 1 and the lead pin 23.

[0053] The limiting protrusion 114 is arranged on the insertion main body 111, the limiting protrusion 114 is arranged conveniently, and the insertion part 11 is convenient to process and manufacture. Certainly, the utility model is not limited to this, and the limiting protrusion 114 can also be arranged on the second end of the roll edge 112.

[0054] Further, as shown in Figure 9 and Figure 10 , the roll edge 112 is two, two first ends of the two roll edges 112 are connected to two ends of the insertion main body 111 in the width direction, and second ends of the two roll edges 112 are wound in a direction close to each other, the second ends of the two roll edges 112 are located between the first ends of the two roll edges 112, and the second ends of the two roll edges 112 and the insertion main body 111 define the insertion slot 113. On the side of the insertion slot 113 away from the insertion main body 111, since the two roll edges 112 exist, the reliability of fixing the lead pin 23 can be improved, the rotation of the lead pin 23 in the insertion slot 113 is avoided, and the lead terminal 1 is prevented from being separated from the lead pin 23.

[0055] In some embodiments of the utility model, as shown in Figure 9 and Figure 10 , the second end of the roll edge 112 is provided with a stop protrusion 1121 on the side facing the insertion main body 111, and when the lead pin 23 is located in the insertion slot 113, the stop protrusion 1121 and the lead pin 23 are arranged and abutted along the insertion direction of the lead pin 23. It can be understood that the stop protrusion 1121 is located downstream of the insertion slot 113 along the insertion direction of the lead pin 23. The stop protrusion 1121 and the lead pin 23 abut, which can limit the lead pin 23 from continuing to insert into the insertion slot 113, limit the insertion depth of the lead pin 23, ensure the reliability of the connection between the lead pin 23 and the lead terminal 1, and thus ensure the reliability of the connection between the lead 3 and the winding 22.

[0056] In addition, it can be understood that when the lead pin 23 abuts against the stop protrusion 1121, the limiting protrusion 114 is just located in the limiting hole 232, and the lead terminal 1 is limited in the insertion direction of the lead pin 23 through the cooperation of the limiting protrusion 114 and the limiting hole 232 and the cooperation of the lead pin 23 and the stop protrusion 1121, so as to ensure the reliability of the connection between the limiting terminal and the lead pin 23.

[0057] In some embodiments of the utility model, as shown in Figure 11As shown, the second end of the crimping edge 112 has a guide slope 1122 towards the side of the surface of the insertion body 111 close to the insertion of the lead pin 23, and the guide slope 1122 is inclined towards the side close to the insertion body 111 in the insertion direction of the lead pin 23, and it can be understood that, due to the arrangement of the guide slope 1122, the insertion port of the insertion slot 113 is formed in a horn shape, facilitating the insertion of the lead pin 23 into the insertion slot 113.

[0058] In addition, in combination with Figure 12 As shown, the end of the lead pin 23 inserted into the insertion slot 113 first has a guide portion 231, and the thickness of the guide portion 231 gradually decreases in the insertion direction of the lead pin 23, and the maximum thickness of the guide portion 231 is the same as the thickness of the remaining part of the lead pin 23, and in addition, the width of the guide portion 231 gradually decreases in the insertion direction of the lead pin 23, and the guide portion 231 plays a guiding role when the lead pin 23 is inserted into the insertion slot 113, facilitating the insertion of the lead pin 23 into the insertion slot 113, and facilitating the cooperation of the lead terminal 1 and the lead pin 23.

[0059] In some embodiments of the utility model, such as Figure 11 As shown, the insertion body 111 is provided with a reinforcing protrusion 1111 protruding into the insertion slot 113, and the limiting protrusion 114 is arranged on the reinforcing protrusion 1111. The reinforcing protrusion 1111 can strengthen the structural strength of the insertion body 111, thereby improving the reliability of the reinforcing protrusion 1111 arranged on the insertion part 11, and further improving the reliability of the limiting protrusion 114 and the limiting hole 232, and ensuring the reliability of the lead terminal 1 and the lead pin 23.

[0060] Among them, such as Figure 11 As shown, the limiting protrusion 114 is formed by the part of the insertion body 111 protruding into the insertion slot 113, and the recess 115 is arranged on the side of the insertion body 111 away from the insertion slot 113 corresponding to the position of the limiting protrusion 114.

[0061] Optionally, the limiting holes 232 are multiple, and the limiting protrusions 114 are multiple corresponding to the multiple limiting holes 232, and the cooperation of the multiple limiting holes 232 and the multiple limiting protrusions 114 can improve the reliability of the fixation between the lead terminal 1 and the lead pin 23. For example, when the limiting holes 232 and the limiting protrusions 114 are both multiple, the multiple limiting protrusions 114 can be arranged in the depth direction of the insertion slot 113, that is, the insertion direction of the lead pin 23, and the corresponding multiple limiting holes 232 are arranged in the insertion direction of the limiting pin; or the multiple limiting protrusions 114 are arranged in a direction perpendicular to the depth direction of the insertion slot 113, and the corresponding multiple limiting holes 232 are arranged in a direction perpendicular to the insertion direction of the limiting pin; or the multiple limiting protrusions 114 are arranged in multiple rows and multiple columns, and correspondingly, the multiple limiting holes 232 are arranged in multiple rows and multiple columns; or the multiple limiting protrusions 114 are arranged at the vertex positions of a polygon, and correspondingly, the multiple limiting holes 232 are arranged at the vertex positions of the corresponding polygon.

[0062] Optionally, as shown in Figure 10 , the cross-sectional area of the limiting protrusion 114 gradually decreases in the direction from the fixed end to the free end of the limiting protrusion 114. For example, in the direction from the fixed end to the free end of the limiting protrusion 114, the side wall of the limiting protrusion 114 is inclined toward the center line of the limiting protrusion 114, and the side wall of the limiting protrusion 114 can guide the limiting protrusion 114 into the limiting hole 232, facilitating the insertion of the limiting protrusion 114 into the limiting hole 232 or the disengagement of the limiting protrusion 114 from the limiting hole 232 during the cooperation and disengagement of the lead terminal 1 and the lead pin 23.

[0063] Optionally, the cross section of the limiting protrusion 114 can be circular, elliptical, or polygonal, such as triangular, quadrangular, or pentagonal, etc. In Figure 10 the example shown, the cross section of the limiting protrusion 114 is circular, and the cross-sectional area of the limiting protrusion 114 gradually decreases in the direction from the fixed end to the free end of the limiting protrusion 114, and the limiting protrusion 114 is formed in a conical or circular truncated shape.

[0064] In some embodiments of the present application, as shown in Figure 9 and Figure 11 , the connecting part 12 includes a base plate 121 and a clamping part 122, one end of the base plate 121 in the length direction is connected with the insertion part 11, and the extension direction of the base plate 121 can be at an angle, for example, perpendicular, to the depth direction of the insertion slot 113, that is, the insertion direction of the lead pin 23. Thus, the connection of the lead 3 and the connecting part 12 is facilitated, and interference of the lead 3 and the connecting part 12 with the insertion of the insertion part 11 and the lead pin 23 is avoided, facilitating the connection of the insertion part 11 and the lead pin 23.

[0065] The substrate 121 is connected to the insertion part 11 at one end along the depth direction of the insertion slot 113. After the lead terminal 1 is inserted into the lead pin 23, the substrate 121 can be connected to the end of the insertion part 11 away from the shell 21 along the depth direction of the insertion slot 113.

[0066] The two sides of the substrate 121 in the width direction are connected to clamping parts 122. The end of the clamping part 122 away from the substrate 121 can be bent towards the substrate 121, and is used to clamp the lead 3 between the substrate 121 and the clamping part 122. In the initial state, the end of the two clamping parts 122 away from the substrate 121 extends in a direction away from each other. When the lead 3 is connected, the lead 3 is placed along the extension direction of the substrate 121, and the end of the two clamping parts 122 away from the substrate 121 is bent towards each other and clamps the lead 3 between the clamping part 122 and the substrate 121, while achieving electrical connection between the substrate 121 and / or the clamping part 122 and the lead 3.

[0067] Further, as shown in Figure 9 and Figure 11 , a plurality of clamping parts 122 are arranged on both sides of the substrate 121 in the width direction, and the plurality of clamping parts 122 on one side of the substrate 121 in the width direction are arranged opposite to the plurality of clamping parts 122 on the other side of the substrate 121 in the width direction. In this way, the clamping reliability of the lead 3 can be improved, and the reliability of the connection between the lead 3 and the connecting part 12 can be ensured. For example, in the example shown in Figure 9 and Figure 11 , two clamping parts 122 are arranged on both sides of the substrate 121 in the width direction, and the two clamping parts 122 on the same side of the substrate 121 in the width direction are arranged at intervals in the length direction of the substrate 121. The clamping part 122 close to the insertion part 11 can be a first clamping part 1221, and the clamping part 122 away from the insertion part 11 can be a second clamping part 1222. The substrate 121 can be arc-shaped at least at the first clamping part 1221 and the second clamping part 1222, thereby facilitating cooperation with the lead 3, improving the clamping effect of the lead 3, and improving the reliability of the fixation of the lead 3.

[0068] In addition, the width of the substrate 121 at the first clamping part 1221 is smaller than the width of the substrate 121 at the second clamping part 1222. The lead 3 includes a wire and a lacquer covering the wire. When the lead 3 is connected, the lacquer at one end of the lead 3 can be removed to expose the internal wire. The first clamping part 1221 is used to clamp the wire portion with the lacquer removed, and the second clamping part 1222 is used to clamp the portion of the lead 3 without the lacquer removed. This not only improves the reliability of the fixation of the lead 3 and the connecting part 12, but also improves the reliability of the electrical connection between the lead 3 and the connecting part 12.
