[0066] In order to make the content easier to understand, the following is a further detailed description based on specific embodiments and in conjunction with the accompanying drawings;

[0067] An outlet box and a motor adapted to connect the inner and outer locks of a wiring socket solve the technical problems of easy loosening, poor versatility, and relatively poor flexibility in use in related technologies. The invention can be manufactured and used, and achieves the positive effects of preventing loosening, relatively good structural reliability, relatively good versatility, and relatively good flexibility in use. The overall concept is as follows:

[0068] One implementation method:

[0069] like Figure 1 、 Figure 2 、 Figure 3 As shown; an outlet box and a motor adapted to connect the inner and outer lock buckles of the wire socket, the outlet box adapted to connect the inner and outer lock buckles of the wire socket, comprising:

[0070] Box body 10;

[0071] The box body 10 has at least one clamping area 11 and a first space 12 for connecting with the connection line socket 100;

[0072] The clamping area 11 includes: a first area 11-1, which is provided on the box body 10; and a second area 11-2, which is provided on the box body 10 and spaced apart from the first area 11-1.

[0073] The first area 11 - 1 and the second area 11 - 2 have different orientations. The first area 11 - 1 faces the outside of the box body 10 and is disposed outside the first space 12 , serving as an external card area.

[0074] The second area 11-2 faces the interior of the box body 10 and is disposed in the first space 12, serving as an inner card area.

[0075] When the connection line socket 100 is inserted into the first space 12, the first area 11-1 is engaged with the outer locking head 101 on the connection line socket 100;

[0076] Alternatively, when the connection line socket 100 is inserted into the first space 12, the second area 11-2 engages with the inner locking head 102 on the connection line socket 100;

[0077] Alternatively, when the connection line socket 100 is inserted into the first space 12, the first area 11-1 engages with the outer locking head 101 on the connection line socket 100, and at the same time, the second area 11-2 engages with the inner locking head 102 on the connection line socket 100;

[0078] Specifically, during implementation, the first area 11-1 and the second area 11-2 have different orientations. The first area 11-1 faces the outside of the box body 10 and is disposed outside the first space 12, serving as an outer card area. The second area 11-2 faces the inside of the box body 10 and is disposed within the first space 12, serving as an inner card area.

[0079] When the connecting wire socket 100 is inserted into the first space 12, the first area 11-1 is engaged with the outer locking head 101 on the connecting wire socket 100;

[0080] Alternatively, when the connection line socket 100 is inserted into the first space 12, the second area 11-2 engages with the inner locking head 102 on the connection line socket 100;

[0081] Alternatively, when the connection cable socket 100 is inserted into the first space 12, the first region 11-1 engages with the outer locking head 101 on the connection cable socket 100, and at the same time, the second region 11-2 engages with the inner locking head 102 on the connection cable socket 100;

[0082] It has the dual functions of internal and external engagement, achieving the goals of relatively good engagement reliability, no loosening, relatively good versatility, and relatively good flexibility of use;

[0083] Another embodiment:

[0084] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown; in implementation, the first area 11-1 is a rectangular groove for engaging with the outer locking head 101;

[0085] The length of the first region 11-1 is greater than the length of the outer locking head 101; the depth of the first region 11-1 is greater than the height of the outer locking head 101. Control of the size helps the outer locking head 101 not to come loose after being inserted into the first region 11-1.

[0086] The second area 11-2 is at least one inner locking protrusion 11-21, which is used to engage with the inner locking head 102;

[0087] The inner locking protrusion 11-21 has a first inclined surface 11-211, a second inclined surface 11-212 and a plane 11-213; the second inclined surface 11-212 connects the first inclined surface 11-211 and the plane 11-213;

[0088] After the inner locking buckle head 102 is inserted, the flat surface 11-213 contacts and abuts against the inner locking buckle head 102. The flat surface 11-213 increases the contact area with the inner locking buckle head 102, making it difficult to loosen. Moreover, after the two contact, the operator can clearly know that they have been inserted into place, and the flexibility of use is relatively good.

[0089] A first inclined surface 11-211 and a second inclined surface 11-212 are provided to form a guide, which is conducive to the smooth insertion of the inner locking head 102;

[0090] The second area 11-2 is arranged in the first space 12, which has the effect of preventing aging and extending the service life, and indirectly reduces the probability of loosening;

[0091] Another embodiment:

[0092] like Figure 5 As shown; in implementation, the box body 10 further has an inclined portion 11-3, the inclined portion 11-3 and the first inclined surface 11-211 are spaced apart opposite each other;

[0093] The inclined portion 11-3 is chamfered or rounded, forming a guide, which is conducive to the outer locking head 101 being smoothly inserted into the first area 11-1, and the operation is relatively convenient;

[0094] Another embodiment:

[0095] like Figure 4 、 Figure 5 、 Figure 13 As shown; when implemented, the box body 10 also has a square through groove 11-4;

[0096] The square through-slot 11-4 is provided between the first region 11-1 and the second region 11-2 and communicates with the first space 12. The volume of the square through-slot 11-4 is smaller than the volume of the outer locking head 101, and the four edges of the top of the square through-slot 11-4 all have first chamfers. The provision of the square through-slot 11-4, which is a process groove, is beneficial for ensuring the injection molding quality of the second region 11-2 during the injection molding of the box body 10. The size and shape of the square through-slot 11-4 are controlled so that the outer locking head 101 will not be accidentally stuck, thereby ensuring the stability of the structure.

[0097] Alternatively, the square through-slot 11-4 is provided on the side wall of the box body 10, close to the first area 11-1, communicated with the first area 11-1, communicated with the first space 12, and facing the second area 11-2, and the width of the square through-slot 11-4 is greater than the width of the second area 11-2, and the width of the square through-slot 11-4 is less than 1 / 2 of the value obtained by subtracting the width of the second area 11-2 from the width of the first space 12; the provision of the square through-slot 11-4 is a process groove, which is beneficial to ensuring the injection molding quality at the second area 11-2 during injection molding of the box body 10;

[0098] Another embodiment:

[0099] like Figure 6 、 Figure 7 As shown; in implementation, a plurality of guide grooves 12-1 and two fool-proof grooves 12-2 are provided in the first space 12; the fool-proof grooves 12-2 are symmetrically arranged on both sides of the guide groove 12-1;

[0100] There are five guide grooves 12 - 1 , which are long strip-shaped grooves and are evenly distributed in the first space 12 ;

[0101] The coil pin 201 passes through the first space 12, through the guide groove 12-1, and then passes through the third space 14 and the fourth space 13-2 to connect with the coil bobbin 200. The provision of the guide groove 12-1 facilitates the assembly of the coil pin 201 and prevents the coil pin 201 from being hit or scratched.

[0102] The foolproof groove 12-2 is a square groove. When plugging with the connecting wire socket 100, the force is more evenly distributed and has a guiding function, which is conducive to the accurate insertion of the connecting wire socket 100 and convenient assembly.

[0103] The explanation of "foolproofing" is that it is a preventive and corrective behavioral restraint method. It uses restrictive methods to avoid errors, allowing operators to intuitively and accurately complete correct operations without expending attention, experience or professional knowledge. This is common knowledge.

[0104] The guide groove 12-1 is further provided with a first anti-scratch portion 12-11, which is a second chamfer or a first rounded corner. The first anti-scratch portion 12-11 serves as a transition and guide when the connecting wire socket 100 is inserted into or removed from the first space 12, and reduces friction resistance, which facilitates the insertion or removal of the connecting wire socket 100 from the first space 12.

[0105] Another embodiment:

[0106] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 As shown; when implemented, the box body 10 also has a second space 13;

[0107] The second space 13 is connected to the first space 12 via a plurality of third spaces 14;

[0108] The second space 13 is a stepped space connected to the coil bobbin 200;

[0109] A plurality of first protrusions 13 - 1 are spaced apart in the second space 13 , and a fourth space 13 - 2 is provided between the first protrusions 13 - 1 , and the fourth space 13 - 2 is in one-to-one communication with the third space 14 ;

[0110] The first protrusions 13-1 are rectangular block structures, and there are four of them. One end of the first protrusion 13-1 has a second anti-scratch portion 13-11, and the second anti-scratch portion 13-11 is a third chamfer or a second rounded corner. The second anti-scratch portion 13-11 is provided to prevent scratching of the coil pin 201 and the enameled wire, and the structural reliability is relatively good.

[0111] The number of the third space 14 and the fourth space 13-2 is five;

[0112] The third spaces 14 and the guide grooves 12-1 are spaced apart and aligned one by one, which is conducive to assembling the coil pins 201. In addition, the spaced apart spaces are process grooves, which can effectively prevent the generation of flash and debris during injection molding, avoid affecting the appearance and performance, and improve assembly efficiency.

[0113] The fourth space 13-2 and the third space 14 form an "L"-shaped structure, which is aligned one-to-one with the coil pins 201 on the coil bobbin 200 to accommodate the coil pins 201. The coil pins 201 are plugged into the connecting wire socket 100 in the first space 12. The "L"-shaped structure facilitates the assembly of the coil pins 201 and prevents collision or scratching of the coil pins 201. The coil pins 201 pass through the first space 12, through the guide groove 12-1, and then through the third space 14 and the fourth space 13-2 to connect with the coil bobbin 200.

[0114] There is a spacing dimension A between the fourth space 13-2 and the guide groove 12-1. The dimension A (for example, A is 5-10 mm) is controlled so that when the coil pin 201 is assembled, the coil pin 201 will not collide with the box body 10 and will not be scratched.

[0115] Among them, two second protrusions 13-3 are also spaced apart in the second space 13, symmetrically arranged on both sides of the first protrusion 13-1, and spaced apart from the first protrusion 13-1. The second protrusions 13-3 are used to fix the coil bobbin 200; the second protrusions 13-3 are of a right-angled trapezoidal block structure, and one end has a third rounded corner 13-31; the second protrusions 13-3 are provided, and when the coil bobbin 200 is assembled with the second space 13, the second protrusions 13-3 play a positioning role for the coil bobbin 200, and the third rounded corner 13-31 plays a transition and guiding role, which is conducive to the coil bobbin 200 being inserted into the second space 13, and the assembly is relatively convenient. In addition, the second protrusions 13-3 are of a right-angled trapezoidal block structure, and the upper end is relatively wide, which has the effect of ensuring structural strength;

[0116] There is an overlap length B between the third space 14 and the coil pin 201. The dimension B (for example, B is 5-10 mm) is controlled. When the connecting wire socket 100 is plugged into the first space 12, the connecting wire socket 100 and the coil pin 201 are plugged into each other. The coil pin 201 is subjected to an upward force. The overlap length B is set. The coil pin 201 can be supported by the inner wall of the box body 10 in the third space 14, which can effectively prevent the coil pin 201 from deforming.

[0117] Another embodiment:

[0118] like Figure 8 、 Figure 11 As shown; when implemented, the box body 10 further has a concave support area 15 on one end portion, the concave support area 15 is spaced apart from the clamping area 11 and is used to support and position the cover plate 300;

[0119] The concave support area 15 includes: a square groove area 15-1; and an arc-shaped expansion area 15-2, which is connected to the square groove area 15-1, and the length of the arc-shaped expansion area 15-2 is greater than the length of the square groove area 15-1;

[0120] The concave support area 15 is provided to increase the contact area with the cover plate 300, which can reliably support and position the cover plate 300 and prevent the cover plate 300 from being deformed during riveting;

[0121] Another embodiment:

[0122] like Figure 8 、 Figure 12 As shown; when implemented, the other end portion of the box body 10 further has an arcuate convex edge 16, and the arcuate convex edge 16 is spaced apart from the clamping area 11;

[0123] The arc-shaped convex edge 16 is provided to effectively guide and direct the coil when assembled with the stator assembly, and to avoid scratching the enameled wire on the coil bobbin 200, thereby ensuring quality and performance;

[0124] Another embodiment:

[0125] like Figure 8 As shown; in implementation, the box body 10 further has a fourth rounded corner 17 and a fourth chamfer 18, and the fourth rounded corner 17 and the fourth chamfer 18 are spaced apart;

[0126] A fourth fillet 17 is provided for contacting the housing 400, thereby reducing the assembly gap with the housing 400 and increasing the contact area with the housing 400, thereby improving the sealing performance and waterproof capability of the motor as a whole. When sealing with glue, the glue is not likely to penetrate into the interior of the motor and affect the normal operation of the motor.

[0127] A fourth chamfer 18 is provided, which plays a guiding role during assembly, facilitates alignment with the housing 400, and makes assembly relatively convenient, thereby improving assembly efficiency;

[0128] About the structure of the motor:

[0129] See Figure 11 、 Figure 12 The motor includes: an outlet box adapted to connect the inner and outer locks of the wire socket;

[0130] The motor further comprises: a connecting wire socket 100, a coil skeleton 200, a coil pin 201, a cover plate 300 and a housing 400;

[0131] The outer locking head 101 or the inner locking head 102 is roughly hook-shaped, which is convenient for engagement;

[0132] The connecting wire socket 100, the outer locking buckle head 101, the inner locking buckle head 102, the coil bobbin 200, the coil pin 201, the cover plate 300, and the housing 400 are not the inventive points of the present invention. They are only provided to better describe the present invention and facilitate understanding of the technical solution of the present invention. After reading the disclosed content, a person of ordinary skill in the art can directly and unambiguously know how to configure them without any creative effort or excessive experimentation.

[0133] The working principle is as follows: the first area 11-1 and the second area 11-2 have different orientations. The first area 11-1 faces the outside of the box body 10 and is located outside the first space 12, serving as an outer card area. The second area 11-2 faces the inside of the box body 10 and is located inside the first space 12, serving as an inner card area.

[0134] When the connecting wire socket 100 is inserted into the first space 12, the first area 11-1 is engaged with the outer locking head 101 on the connecting wire socket 100;

[0135] Alternatively, when the connection line socket 100 is inserted into the first space 12, the second area 11-2 engages with the inner locking head 102 on the connection line socket 100;

[0136] Alternatively, when the connection cable socket 100 is inserted into the first space 12, the first region 11-1 engages with the outer locking head 101 on the connection cable socket 100, and at the same time, the second region 11-2 engages with the inner locking head 102 on the connection cable socket 100;
