[0049] Hereinafter, with reference to the accompanying drawings, the first connection terminal 10 of the electronic water pump 200 according to an embodiment of the present invention will be described.

[0050] Reference Figures 1-9 As shown, the first connection terminal 10 of the electronic water pump 200 according to the present utility model embodiment may include: a first connection part 101, a second connection part 102 and a third connection part 103.

[0051] The first connecting part 101 is used for electrical connection with the stator body 50 of the electronic water pump 200, and the second connecting part 102 is used for electrical connection with the female connector of the electronic water pump 200. The connector is used for connection with an external power source. The first connecting part 101 and the second connecting part 102 are electrically connected to each other through the third connecting part 103 to realize power supply to the stator body 50 of the electronic water pump 200. For example, the stator body 50 includes a stator winding 501 and a stator core 502. The first connecting part 101 can be used for electrical connection with the stator winding 501; or, the first connecting part 101 can be used for electrical connection with the stator core 502. Specifically, the first connecting part 101 can be welded to the stator body 50, plugged in, snapped in, or made of elastic contact, etc. By connecting the first connecting part 101 and the second connecting part 102 into one unit through the third connecting part 103, the number of parts of the stator body 50 can be reduced, and the production cost of the stator body 50 can be reduced.

[0052] In related technologies, the stator connection portion and the connector connection portion are arranged sequentially along a second direction. Given a fixed relative position between the stator connection portions of adjacent connection terminals, the connector connection portions of adjacent connection terminals need to be spaced apart in the second direction to meet certain design requirements. If the distance between the stator connection portion and the connector connection portion of one of the two adjacent connection terminals is directly reduced, the distance between the positioning connection portion and the connector connection portion in the second direction will become too close. This will cause the connector connection portion to interfere with the tooling, preventing the tooling from removing excess enameled wire connected to the stator connection portion.

[0053] In this application, the first connecting portion 101 and the second connecting portion 102 are arranged along the first direction F1, and the third connecting portion 103 connects the first connecting portion 101 and the second connecting portion 102 to the same end in the second direction F2. That is, the first connecting portion 101 and the second connecting portion 102 are both located on the same side of the third connecting portion 103, wherein the first direction F1 is perpendicular to the second direction F2. Since the first connecting portion 101 and the second connecting portion 102 are arranged along the first direction F1, the first connecting portion 101 and the second connecting portion 102 will be spaced apart in the first direction F1, leaving space. Therefore, no matter whether the distance between the first connecting portion 101 and the second connecting portion 102 in the second direction F2 is large or small, it is unlikely to affect the subsequent process of cutting off excess enameled wire. Thus, the relative position design of the second connecting portion 102 in the second direction F2 is more flexible and less restricted.

[0054] In some embodiments, the electric water pump 200 includes a stator assembly 100, which includes a stator body 50 and a plurality of connection terminals 40. Each connection terminal 40 includes a stator connection portion 401 and a connector connection portion 402. The stator connection portion 401 is electrically connected to the stator body 50, and the connector connection portion 402 is electrically connected to the female connector of the electric water pump 200. At least one connection terminal 40 is a first connection terminal 10 disclosed in this application embodiment. The first connection portion 101 is formed as a stator connection portion 401, and the second connection portion 102 is formed as a connector connection portion 402. When the first connection terminal 10 serves as a connection terminal 40 in the stator assembly 100 of the electric water pump 200, the arrangement of the second connection portion 102 of the first connection terminal 10 in the second direction F2 is more flexible, thus facilitating the spatial arrangement of the connector connection portions 402 of various connection terminals 40.

[0055] According to some embodiments of this utility model, the second connecting portion 102 includes a first segment 1021 and a second segment 1022. The first segment 1021 extends along the second direction F2 and one end of the first segment 1021 is connected to the third connecting portion 103. The second segment 1022 extends along the third direction F3 and is connected to the other end of the first segment 1021. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other. It should be noted that, since the first connecting portion 101 and the second connecting portion 102 are arranged along the first direction F1 in this application, that is, the second segment 1022 and the first connecting portion 101 are arranged in the first direction F1, even if the distance between the second segment 1022 and the first connecting portion 101 in the second direction F2 is too small, since the second segment 1022 and the first connecting portion 101 are spaced a certain distance apart in the first direction F1, leaving space for wire cutting, the second segment 1022 will not affect the subsequent wire cutting operation.

[0056] Furthermore, provided that the connection position between the first connecting part 101 and the stator body 50 remains unchanged, the first connecting terminal 10 of this application can also change the distance between adjacent second connecting parts 102 in the first direction F1 by changing the size of the third connecting part 103 and the distance between the first connecting part 101 and the second connecting part 102 in the first direction F1 within a certain range.

[0057] According to the first connection terminal 10 of the electronic water pump 200 of this utility model embodiment, by arranging the first connection portion 101 and the second connection portion 102 along the first direction F1, and the third connection portion 103 connecting the first connection portion 101 and the second connection portion 102 at the same end in the second direction F2, the first connection portion 101 and the second connection portion 102 will reserve space in the first direction F1, thereby making the arrangement of the relative spatial positions of the first connection portion 101 and the second connection portion 102 in the first direction F1 and the second direction F2 more flexible and less restricted, and can meet more design requirements.

[0058] In some embodiments, reference may be made to 1 and Figure 2 As shown, in the first direction F1, the distance D between the first connecting portion 101 and the second connecting portion 102 is greater than or equal to 0.5 cm. In other words, the distance D between the end of the first connecting portion 101 near the second connecting portion 102 in the first direction F1 and the end of the second connecting portion 102 near the first connecting portion 101 in the first direction F1 is greater than or equal to 0.5 cm. For example, the distance between the first connecting portion 101 and the second connecting portion 102 can be 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm, or any value between any two of these values, etc. The distance between the first connecting portion 101 and the second connecting portion 102 can be selected according to the specific winding process and connector model. In this way, the second connecting portion 102 of the first connecting terminal 10 is less likely to affect the subsequent wire cutting operation.

[0059] In some embodiments, reference may be made to Figures 1-3 As shown, the first connecting part 101 has a wire-clamping hole 1011 extending along a third direction F3. The wire-clamping hole 1011 extends along a second direction F2, and one end of the wire-clamping hole 1011 has a piercing groove 1012. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other. When installing the first connecting terminal 10, the piercing groove 1012 is used to pierce the enameled wire, and the wire-clamping hole 1011 is used to clamp the pierced enameled wire, realizing the clamping and fixing of the enameled wire and electrical connection. This eliminates the welding process, resulting in high connection efficiency and good connection effect. The conductor in the enameled wire can be copper wire or aluminum wire.

[0060] like Figures 4 to 8As shown, the stator assembly 100 disclosed in this application embodiment includes a stator body 50 and a plurality of connection terminals 40. The connection terminals 40 include a stator connection portion 401 and a connector connection portion 402. The stator connection portion 401 is used for electrical connection with the stator body 50, and the connector connection portion 402 is used for electrical connection with the female connector of the electronic water pump 200. At least one connection terminal 40 is a first connection terminal 10 disclosed in this application embodiment. The first connection portion 101 is formed as a stator connection portion 401, and the second connection portion 102 is formed as a connector connection portion 402.

[0061] For example, the stator body 50 may include an insulating support 508, a stator winding 501, and a stator core 502. The insulating support 508 is disposed on the stator core 502, and the stator winding 501 is disposed on the insulating support 508. Some of the multiple connecting terminals 40 can be electrically connected to the stator core 502, and other parts of the multiple connecting terminals 40 can be electrically connected to the multiple stator windings 501. In addition, the multiple connecting terminals 40 can all be detachably connected to the insulating support 508, for example, the multiple connecting terminals 40 can all be plugged into the insulating support 508.

[0062] Since the first connecting terminal 10 according to the present invention has the above-mentioned beneficial effects, the stator assembly 100 according to the present invention, by arranging the first connecting portion 101 and the second connecting portion 102 along the first direction F1, and the third connecting portion 103 connecting the first connecting portion 101 and the second connecting portion 102 at the same end in the second direction F2, will reserve space for the first connecting portion 101 and the second connecting portion 102 in the first direction F1. This makes the arrangement of the relative spatial positions of the first connecting portion 101 and the second connecting portion 102 in the first direction F1 and the second direction F2 more flexible and less restricted, and can meet more design requirements. For example, the arrangement of the connector connecting portions 402 between multiple connecting terminals 40 is more flexible.

[0063] Furthermore, when the first connecting terminal 10 serves as the connecting terminal 40 in the stator assembly 100 of the electronic water pump 200, the arrangement position of the second connecting portion 102 of the first connecting terminal 10 in the second direction F2 is more flexible, thus allowing for greater flexibility in the spatial arrangement of the connector connecting portions 402 of adjacent connecting terminals 40, which is beneficial for meeting the spatial arrangement requirements of the connector connecting portions 402 of various connecting terminals 40.

[0064] According to some embodiments of this utility model, it can be referred to Figure 4 and Figure 6As shown, the stator connection portions 401 of multiple connection terminals 40 are spaced apart along a first direction F1, and the connector connection portions 402 of the multiple connection terminals 40 are arranged in multiple rows along a second direction F2. Each row includes one connector connection portion 402 or multiple connector connection portions 402 spaced apart along the first direction F1. For example, the connector connection portions 402 of the multiple connection terminals 40 are arranged in two rows along the second direction F2, one row including one connector connection portion 402 and the other row including three connector connection portions 402; or, one row including two connector connection portions 402 and the other row including two connector connection portions 402. Alternatively, the connector connection portions 402 of the multiple connection terminals 40 are arranged in three rows along the second direction F2, two rows each including one connection terminal 40 and the other row including two connection terminals 40. In practice, the design can be flexibly adapted to requirements.

[0065] According to some embodiments of this utility model, it can be referred to Figure 4 As shown, adjacent rows of connector connection portions 402 are arranged intersectingly along the first direction F1. In other words, the projections of adjacent rows of connector connection portions 402 on the second direction F2 do not overlap. In this way, the distance between connector connection portions 402 in the first direction F1 can be minimized, while the spatial distance between adjacent connector connection portions 402 can be maximized. This facilitates a more compact spatial arrangement of multiple connector connection portions 402, and maintains a certain safe distance between adjacent connector connection portions 402.

[0066] For example, the stator body 50 includes a stator winding 501, and a plurality of connection terminals 40 include two first connection terminals 10 and one second connection terminal 20 electrically connected to the stator winding 501. The stator connection portions 401 of the two first connection terminals 10 are disposed on both sides of the stator connection portions 401 of the second connection terminal 20 along a first direction F1. The connector connection portions 402 of the second connection terminal 20 are located on one side of the stator connection portions 401 of the second connection terminal 20 along a second direction F2. The connector connection portions 402 of the first connection terminals 10 are located on the side of the connector connection portions 402 of the second connection terminal 20 closer to the stator body 50.

[0067] According to some embodiments of this utility model, the two first connecting terminals 10 are symmetrical about the center line of the second connecting terminal 20. This allows the two first connecting terminals 10 to be stamped using the same set of molds, reducing the number of molds and lowering molding costs. Furthermore, the distance between the connector connecting portion 402 of the second connecting terminal 20 and the connector connecting portions 402 of the two first connecting terminals 10 in the first direction F1 is equal, and the distance between the connector connecting portion 402 of the second connecting terminal 20 and the connector connecting portions 402 of the two first connecting terminals 10 in the second direction F2 is also equal, thus improving the regularity of the multiple connector connecting portions 402.

[0068] In some embodiments, the distance between the connector connection portion 402 of the second connection terminal 20 and the connector connection portions 402 of the two first connection terminals 10 in the second direction F2 may be equal or unequal, and the distance between the connector connection portion 402 of the second connection terminal 20 and the connector connection portions 402 of the two first connection terminals 10 in the first direction F1 may be equal or unequal. In practice, the appropriate option can be selected based on the requirements.

[0069] According to some embodiments of this utility model, the stator body 50 includes a stator core 502, and the outer peripheral surface of the stator core 502 is provided with a connecting protrusion 503. Multiple connecting terminals 40 include a grounding terminal 30, and the stator connecting portion 401 of the grounding terminal 30 is at least inserted into the connecting protrusion 503. By connecting the grounding terminal 30 to the stator core 502, the EMC performance of the electronic water pump 200 can be enhanced. EMC performance (electromagnetic compatibility) refers to the ability of an equipment to neither interfere with other equipment nor be interfered with by the electromagnetic energy of other equipment. The stator connecting portion 401 of the grounding terminal 30 is at least inserted into the connecting protrusion 503. That is, the stator connecting portion 401 of the grounding terminal 30 can be inserted only into the connecting protrusion 503, or it can be connected to both the connecting protrusion 503 and the stator core 502 simultaneously. This results in a large connection area between the grounding terminal 30 and the stator core 502, reducing the possibility of connection failure between the grounding terminal 30 and the stator core 502. For example, the grounding terminal 30 includes an interference portion 302, and the stator core 502 includes a insertion slot 5021. The interference portion 302 and the insertion slot 5021 are interference-fitted to further ensure a good connection between the stator core 502 and the grounding terminal 30; for example, the axial end faces of the grounding terminal 30 and the stator core 502 abut against each other.

[0070] In some embodiments, the fourth connection portion 301 of the grounding terminal 30 is provided with blocks on both sides of the third direction F3 to support the fourth connection portion 301 on the third direction F3 and reduce the possibility of deformation of the fourth connection portion 301.

[0071] According to some embodiments of this utility model, it can be referred to Figure 5 and Figure 6As shown, the stator connection portion 401 and connector connection portion 402 of the grounding terminal 30 are arranged along the first direction F1, and the connector connection portion 402 extends along the third direction F3. The grounding terminal 30 also includes a fourth connection portion 301, which connects one end of the stator connection portion 401 in the second direction F2 and one end of the connector connection portion 402 in the third direction F3. In this application, by providing the fourth connection portion 301 to connect the stator connection portion 401 and the connector connection portion 402 of the grounding terminal 30, the distance between the stator connection portion 401 and the connector connection portion 402 in the first direction F1, the second direction F2, and the third direction F3 can be changed by altering the dimensions of the fourth connection portion 301 in the first direction F1, the second direction F2, and the third direction F3. This makes the spatial arrangement of the stator connection portion 401 and the connector connection portion 402 of the grounding terminal 30 more flexible and better meets the various arrangement requirements of the connection terminals 40.

[0072] In some specific embodiments, reference can be made to Figure 5 The fourth connecting part 301 includes a first part and a second part connected together. The first part extends along a third direction F3, and the second part extends along a first direction F1. The first part is connected to one end of the stator connecting part 401 in the second direction F2, and the second part is connected to one end of the connector connecting part 402 in the third direction F3. The stator connecting part 401 of the first connecting terminal 10 and the stator connecting part 401 of the grounding terminal 30 are arranged at intervals along the first direction F1. The connector connecting part 402 of the grounding terminal 30 is located on the side of the stator connecting part 401 of the first connecting terminal 10 away from the stator body 50.

[0073] According to some embodiments of this utility model, it can be referred to Figure 6 As shown, the stator body 50 has a first slot 504 and a second slot 505 arranged along a first direction F1. The first slot 504 and the second slot 505 are separated by a partition 506. The first connecting portion 101 of the first connecting terminal 10 is inserted into the first slot 504 along a second direction F2, the second connecting portion 102 of the first connecting terminal 10 is inserted into the second slot 505 along a second direction F2, and the third connecting portion 103 of the first connecting terminal 10 is supported by the partition 506 along a second direction F2. This facilitates the stable installation of the first connecting terminal 10 on the stator body 50, prevents the first connecting terminal 10 from easily detaching from the stator body 50, and allows the stator body 50 to provide support for the first connecting terminal 10, thus reducing the possibility of significant deformation of the first connecting terminal 10.

[0074] In some embodiments, reference may be made to Figure 7As shown, the partition 506 has a limiting protrusion 507 on its side facing the third connecting part 103. The limiting protrusion 507 is located on both sides of the third connecting part 103 in the third direction F3 to support the third connecting part 103. As a result, the third connecting part 103 is less prone to deformation.

[0075] According to some embodiments of this utility model, it can be referred to Figure 4 and Figure 8 As shown, the second slot 505 has an open slot on one side along the third direction F3, so that the second segment 1022 of the second connecting part 102 of the first connecting terminal 10 can extend out of the second slot 505 along the third direction F3. The side wall and bottom wall of the slot 505 opposite to the open slot are connected by an arc surface 5051. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other. The second connecting part 102 includes a first segment 1021 and a second segment 1022. The first segment 1021 extends along the second direction F2 and one end of the first segment 1021 is connected to the third connecting part 103. The second segment 1022 extends along the third direction F3 and is bent and connected to the other end of the first segment 1021. The bent connection 1023 is supported by the arc surface 5051. In this way, the second slot 505 has a larger supporting area for the first connecting terminal 10, the support is more stable, and the first connecting terminal 10 is less likely to deform under external force. The bent connection 1023 is supported on the arc surface 5051. Here, the bent connection can be supported on the arc surface 5051 after the first connecting terminal 10 is subjected to external force; or, the bent connection can be only partially supported on the arc surface 5051; or, the bent connection can be fully supported on the arc surface 5051.

[0080] The first connection terminal 10 includes a first connection portion 101, a second connection portion 102, and a third connection portion 103. The first connection portion 101 and the second connection portion 102 are arranged along a first direction F1.

The first connection portion 101 forms a stator connection portion 401, and the second connection portion 102 forms a connector connection portion 402.

[0081] In the first direction F1, the distance between the first connecting part 101 and the second connecting part 102 is greater than or equal to 0.5 cm. The first connecting part 101 is provided with a wire-locking hole 1011 that extends through the third direction F3.

[0082] The insulating bracket 508 is provided with a first slot 504 and a second slot 505 arranged along the first direction F1.

The third connecting part 103 of the first connecting terminal 10 is supported on the partition 506 along the second direction F2.

[0083] The second slot 505 has an open slot on one side along the third direction F3. The side wall and bottom wall of the slot 505 opposite to the open slot are connected by an arc surface 5051. The second connecting part 102 includes a first segment 1021 and a second segment 1022.
