Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to a motor terminal assembly and a motor. Background Art

[0002] In a traditional motor structure, multiple terminals are arranged separately, and each terminal is protected by an insulating sealing sleeve on the outside. However, this terminal structure takes up space and is inconvenient to install. Therefore, the existing terminal structure usually adopts a quick-plug terminal structure, such as the utility model patent with authorization announcement number CN208508674U, in which the metal terminal and the terminal seat are fastened together by bolts, or as in the utility model patent with authorization announcement number CN204810069U, a terminal sleeve is provided, and a plurality of terminal sleeve cavities for installing the terminals are provided in the terminal sleeve, and the terminal is fixed in the terminal sleeve cavity by interference fit or snap connection. The above connection methods all use bolt connection, interference fit or snap connection, etc. This type of connection structure has some problems. For example, the connection method between the terminal and the socket / sheath makes it easy to loosen during long-term use, and the stability of the terminal connection cannot be ensured. When the terminal is loose, it is easy to have poor contact. In addition, interference fit and other methods are also easy to cause increased resistance. In addition, the connection structure of the above terminal is difficult to ensure its sealing performance. The complex connection structure increases the occupied space of the terminal assembly on the one hand, and increases the production cost of the terminal assembly on the other hand. Therefore, it is necessary to provide a terminal assembly with high stability, good sealing performance and simple connection structure. Utility Model Content
