TECHNICAL FIELD

[0001] The utility model relates to motor design technical field, concretely is a kind of integrated motor rear end cover connector. BACKGROUND

[0002] In the current motor assembly structure, the connector exists in the form of an independent part and is connected with the motor end cover, and the connection mode mainly fixes them together by means of four screws to realize the fastening connection of the two.

[0003] This traditional connection mode, since the connector occupies a certain space as an independent individual, and in order to be able to accommodate the four screws and the connecting pieces such as nuts and washers matched therewith, sufficient space area must be reserved around the motor end cover and the connector, so that the overall installation space is greatly increased. In some small motor equipment with extremely strict space requirements or electrical devices with compact internal structure layout, the additional space requirement may cause the volume of the entire equipment to exceed the expected design range, thereby affecting the portability, installation adaptability and layout rationality in limited space of the equipment.

[0004] Since the independent connector itself needs certain materials to be manufactured, whether it is the shell material or the internal conductive structure consumes corresponding raw materials, and the four connecting screws and the matched nuts, washers and the like also need metal materials to be produced. These additional materials increase the material cost of the motor. And the traditional connection mode involves multiple steps of manual operation. The worker needs to first place the connector in the specified position of the motor end cover, then picks up the screws one by one, and uses tools to screw them into the corresponding threaded holes.
