However, when the stator is connected to the controller and the corresponding terminal, the required installation volume is large, and the installation process is relatively cumbersome. Utility Model Content

[0003] In view of the deficiencies in the prior art, one of the objectives of this application is to provide a quick connection structure for a stator, which has the advantages that the terminal is directly connected to the stator winding without a controller, making the installation process more convenient and reducing the installation volume.

[0006] By adopting the above technical solutions, the external connection portion is inserted into the contact member and directly connected to the stator winding, reducing the installation volume and making the installation process more convenient without a controller. The limiting portion defines the distance between the external connection portion and the stator winding to prevent the external connection portion from damaging the stator winding.

[0010] By adopting the above technical solutions, the protrusion can easily enter the groove and is not easy to exit, making the installation of the contact member more convenient.

[0011] In a preferred example of this application, it can be further configured as: the contact member further includes a deformation groove for enabling the contact member to deform during installation.

[0012] By adopting the above technical solution, it is easier for the contact member to enter the installation groove.

[0013] In a preferred example of the present application, it can be further configured that: there is a notch on the deformation groove, and the notch is for the wire to pass through and disperse the force received by the contact member.

[0019] In a preferred example of the present application, it can be further configured that: there is a receiving area on some of the passing sleeves, and the receiving area is used to receive a part of the insertion member.

[0020] By adopting the above technical solution, the cooperation between the receiving area and the insertion member realizes the purpose that when the external connection part is subjected to an external tensile force, it is not easy to be disengaged from the connection cavity.

[0021] In a preferred example of the present application, it can be further configured that: the insertion member includes a guiding surface, a limiting surface and a deformation area, the guiding surface is used to guide the passing sleeve into the connection cavity, the limiting surface is used to prevent the external connection part from withdrawing from the connection cavity, and the deformation area is used to enable the passing sleeve to pass through the insertion member.

[0022] By adopting the above technical solution, when the external connection part enters the connection cavity, the passing sleeve contacts the guiding surface, causing the deformation area to deform, enabling the passing sleeve to continue to pass through, and enabling a part of the insertion member to enter the receiving area. When the external connection part is subjected to an external tensile force, the limiting surface contacts the passing sleeve and prevents the external connection part from withdrawing from the connection cavity.

Detailed implementation manners

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Refer to Figures 1 to 3 , a quick-connection structure of a stator disclosed in the present application, includes a housing 1, a contact 2, an installation groove 3 and an external connection part 4. The installation groove 3 is provided on the stator winding 5. There is a groove on the installation groove 3 for limiting the position of the contact 2. The contact 2 is connected to the stator winding 5 through the installation groove 3. The external connection part 4 is used to communicate with a power source. The external connection part 4 is inserted into the contact 2 and is connected to the stator winding 5 through the contact 2. The external connection part 4 includes an insertion part 41 and a plurality of passing sleeves 42. In this embodiment, the numbers of the contact 2, the installation groove 3 and the external connection part 4 are set to three groups. For the convenience of description, the groove is not shown, and the number and shape of the groove can be set according to the shape of the contact 2. The length of the number of the passing sleeves 42 can be set as required.

[0029] The housing 1 includes a limiting part 7 and a connection cavity 6. The limiting part 7 is used to limit the distance between the external connection part 4 and the stator winding 5. The connection cavity 6 is used to accommodate the external connection part 4. The limiting part 7 is provided on the connection cavity 6. There is an extending part 61 on the connection cavity 6. The extending part 61 is used to extend into the external connection part 4. The extending part 61 includes a guiding surface 62, a limiting surface 63 and a deformation area 64. The guiding surface 62 is used to guide the passing sleeve 42 into the connection cavity 6. The limiting surface 63 is used to prevent the external connection part 4 from withdrawing from the connection cavity 6. The deformation area 64 is used to enable the passing sleeve 42 to pass through the extending part 61. There is a connection column on the housing 1 for grounding and avoiding interference.

[0030] The contact 2 includes a pressing plate 21, a protrusion 22 and a deformation groove 23. The protrusion 22 is used to cooperate with the groove. The pressing plate 21 is used to apply a force to the external connection part 4. The protrusion 22 includes a guiding surface 24 and an anti-disengagement surface 25. The guiding surface 24 is used to guide the protrusion 22 into the groove. The anti-disengagement surface 25 is used to prevent the protrusion 22 from withdrawing from the groove. The deformation groove 23 is used to enable the contact 2 to generate deformation during installation. There is a notch 26 on the deformation groove 23 for the wire to pass through and disperse the force received by the contact 2.

[0031] The insert 41 is used to contact the pressure plate 21. The passage sleeve 42 and the insert 41 form a through groove for the wire to pass through. The passage sleeve 42 is also used to cooperate with the limiting part 7. A receiving area 43 is provided on a part of the passage sleeve 42, and the receiving area 43 is used to receive a part of the inserting member 61.

[0032] When installing the contact member 2, the contact member 2 is deformed through the deformation groove 23, so that the protrusions 22 on both sides of the contact member 2 approach each other, making it easier for the contact member 2 to enter the installation groove 3 until the positions of the protrusions 22 and the grooves correspond to each other, and then the contact member 2 returns to its original state. The cooperation between the protrusions 22 and the grooves limits the position of the contact member 2.

[0033] When the external connection part 4 enters the connection cavity 6, the passage sleeve 42 contacts the guiding surface 62, causing the deformation area 64 to deform, so that the passage sleeve 42 can continue to pass through, allowing a part of the inserting member 61 to enter the receiving area 43, and making the insert 41 contact the pressure plate 21, so that the insert 41 is directly connected to the stator winding 5 through the contact member 2. The outermost passage sleeve 42 abuts against the limiting part 7, preventing the insert 41 from moving further and avoiding damage to the stator winding 5. When the external connection part 4 is subjected to an external pulling force, the limiting surface 63 contacts the passage sleeve 42 and prevents the external connection part 4 from withdrawing from the connection cavity 6.

[0034] The implementation principle of this embodiment is as follows: The external connection part 4 is inserted into the contact member 2 and directly connected to the stator winding 5, without the need for a controller, which reduces the installation volume and makes the installation process more convenient. The limiting part 7 limits the distance between the external connection part 4 and the stator winding 5 to prevent the external connection part 4 from damaging the stator winding 5. The cooperation between the protrusions 22 and the grooves makes the connection between the contact member 2 and the stator winding 5 firm. The pressure plate 21 applies a force to the external connection part 4, making the connection between the external connection part 4 and the stator winding 5 more stable.

[0035] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
