DETAILED DESCRIPTION
[0026] The utility model will be further described below in combination with the drawings. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.
[0028] In the description of the utility model, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances. Example 1
[0029] Referring to Figure 1The utility model introduces a kind of motor launch package stator and PCB board connecting structure of hook type, for improving the connection stability and production efficiency of motor launch package stator and PCB board.The structure includes motor launch package stator 1 and a with it connected PCB board 2.Motor launch package stator 1 is composed of insulating support 11 and silicon steel sheet 12, and silicon steel sheet 12 is tightly covered on the outer surface of insulating support 11, to enhance its electromagnetic performance and structural strength.The center of insulating support 11 is equipped with a center ring 3, and multiple bolts 4 and hooks 5 are evenly distributed on the circumference of center ring 3, and the bolt 4 and hook 5 protrude from the bottom of center ring 3, for being clamped with the structure on the PCB board 2.
[0030] In particular, no upper insulating pillar 6 is provided on the insulating support 11 corresponding to the hook 5, and such arrangement allows the hook 5 to move freely and be clamped with the PCB clamping slot 22 on the PCB board 2, thereby simplifying the assembly process and improving the flexibility of the structure.
[0031] The PCB board 2 is provided with multiple PCB clamping slots 22, and the PCB clamping slot 22 is matched with the bolt 4 and hook 5, for realizing the mechanical clamping between the motor launch package stator 1 and the PCB board 2. Such connection mode not only provides stable mechanical connection, but also solves the problem of reverse groove in mold production by canceling the upper insulating pillar 6 in traditional structure, reduces the mold cost, and improves the mass production.
[0032] In addition, the design of the structure also considers the size limitation of the motor, especially for the motor with an outer diameter greater than 50mm, the structure replaces the traditional bolt design by hook design, effectively solves the problem of the combination strength of the stator and the PCB board, and avoids the difficulty of mold opening caused by the problem of reverse groove in mold production.
[0033] In summary, the hook type connecting structure simplifies the design and improves the connection mode, not only improves the connection stability and production efficiency of the motor launch package stator and the PCB board, but also reduces the production cost, and is suitable for motors of various sizes, especially for the manufacture of large motors. Example 2

Among them, the outer surface of the center ring 3 is uniformly provided with multiple connecting plates 11, which connect the center ring 3 and the wing plate 7, to enhance the stability of the overall structure. The surface of the connecting plate 9 is used for winding wire, and the outer surface of the wing plate 7 is covered with silicon steel sheet 12, which not only improves the electromagnetic performance, but also enhances the mechanical strength of the structure. The silicon steel sheet 12 is made of silicon-containing ferroalloy, which is selected due to its excellent magnetic properties.
[0035] In order to facilitate mass production, a plurality of lower insulating pillars 6 are arranged on the airfoil plate 7, and the lower insulating pillars 6 corresponding to the top position of the clamping hook 5 are not arranged.
[0036] Referring to Figure 2 , the top of the clamping hook 1 is provided with a chamfer 10 for positioning and guiding the insertion of the clamping hook 5 into the PCB card slot 22, ensuring the precise docking of the clamping hook 5 with the PCB card slot 22, and avoiding deviation or misplacement during installation. The insulating support 11 is made of plastic material, which is selected because of its light weight and good insulating performance.
[0037] Referring to Figure 3 , a plurality of through holes 23 are arranged on the PCB 2, which are used to position the lower insulating pillars 6 on the PCB 2, ensuring the accurate installation of the lower insulating pillars 6.
[0038] Referring to Figure 4 , the bottom of the insulating support 11 is provided with an upper insulating boss 8 for supporting the motor launch package stator 1, providing additional mechanical support and electrical insulation. The surface of the insulating support 11 can also be coated with an anti-arc layer, further improving its insulating performance and anti-arc erosion ability. This design not only improves the reliability of the connection structure, but also reduces the production cost, and is suitable for various sizes of motors, especially large motors.
[0039] Working principle:
[0040] The motor launch package stator 1 is connected to the PCB 2 through the latch 4 and the clamping hook 5. The latch 4 provides vertical fixing force, while the three clamping hooks 5 provide horizontal fixing force. When the latch 4 is inserted into the hole of the PCB 2, the clamping hook 5 is buckled with the special structure on the PCB 2, together realizing the stable fixation of the motor launch package stator 1. The insulating pillar 6 is arranged at the top of the insulating support corresponding to the clamping hook 5 (i.e. the top of the airfoil plate 7), ensuring the electrical insulation performance of the motor launch package stator 1 during connection, preventing short circuit or other electrical faults.
[0041] The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principle of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection range of the present application.
