[0002] With the development of science and technology, more and more smart appliances are entering people's daily lives. Due to the high degree of intelligence, smart appliances need to integrate more electronic components inside the product, and EMI is inevitable. However, the demand for user experience is getting higher and higher. Product EMI suppression is a powerful weapon to improve product competitiveness. As one of the main sources of EMI, motors have become the key control object of smart appliance manufacturers. Therefore, reducing motor EMI is an issue that must be considered in motor design.

[0003] A common method for EMI suppression is to add EMI suppression elements 14 to the product, mainly capacitors, inductors, varistors, etc. The addition of these elements complicates motor manufacturing and reduces production efficiency. The traditional assembly solution is to connect the inductor and capacitor to the motor terminals by soldering. Soldering has high requirements for operators, who generally need professional training to have the ability to weld, and require long-term training to improve efficiency. Despite this, production efficiency is still low and quality problems such as cold soldering often exist. Labor costs remain high and corporate competitiveness declines.

[0004] Therefore, there is an urgent need to design a motor with built-in EMI components to overcome the above-mentioned deficiencies of one or more prior arts. Summary of the invention

[0006] In a preferred embodiment, the connecting terminal and the brush are respectively provided with a clamping block extending outward, and the U-shaped clamping groove is located at the top and / or bottom of the clamping block.

[0007] The beneficial effects of the utility model are as follows: by arranging U-shaped slots on the connecting terminals and the brushes, the leads of the suppression components are clamped into the U-shaped slots, the installation process is simplified, the production efficiency is improved, there is no need to train the staff, the labor cost can be effectively reduced, and the connection quality is guaranteed by the clamping method, thereby improving the competitiveness of the product.

[0014] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0015] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present utility model, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present utility model.

[0016] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0017] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0018] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. Therefore, the utility model is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-Figure 4 As shown, the utility model provides a motor with built-in EMI components, including: a motor body 10, one end of the motor body 10 is buckled with an end cover 11, a connecting terminal 12 and a brush 13 are installed in the end cover 11, the connecting terminal 12 is connected to the motor body 10, the motor body 10 is connected to the outside world through the connecting terminal 12, the connecting terminal 12 and / or the brush 13 are provided with a U-shaped groove 15, and a suppression element 14 is also provided in the end cover 11, and the lead of the suppression element 14 is snap-connected with the corresponding U-shaped groove 15.

[0020] Furthermore, the connecting terminal 12 and the brush 13 are respectively provided with a clamping block 16 extending outward, and the U-shaped clamping groove 15 is located at the top and / or bottom of the clamping block 16 .

[0021] Specifically, in order to solve the problem that the suppression element 14 in the prior art needs to be welded, resulting in low production efficiency and difficulty in ensuring welding quality, a motor with a built-in EMI element is provided, which includes a motor body 10, and the motor body 10 is composed of a rotor, a stator, and a housing. An end cover 11 is clamped at one end of the motor body 10, and a connecting terminal 12 and a brush 13 are arranged in the end cover 11. The brush head of the brush 13 contacts the rotor, and the connecting terminal 12 is electrically connected to the rotor. The connecting terminal 12 is used to be electrically connected to an external power supply. At least one suppression element 14 is installed, and the suppression element 14 can be an inductor or a capacitor, etc. At the same time, a card block 16 extending out is respectively provided on the inner side wall of the connecting terminal 12 and the brush 13, and a U-shaped card groove 15 is respectively provided at the upper and lower ends of the card block 16. When installing, the lead of the suppression element 14 is stuck in the U-shaped card groove 15 and is electrically connected to the U-shaped card groove 15. This method does not require welding, and does not require training for staff, which can effectively reduce labor costs, and is simple to install, which can effectively improve production efficiency.

[0022] In summary, the utility model provides a U-shaped slot 15 on the connecting terminal 12 and the brush 13, so that the lead of the suppression element 14 is snapped into the U-shaped slot 15, thereby simplifying the installation process and improving production efficiency. There is no need to train staff, which can effectively reduce labor costs. The connection quality is guaranteed by the snap-on method, thereby improving the competitiveness of the product.
