Description

New forms of energy motor controller changes pencil sealing washer structure soon Technical Field The utility model relates to the technical field of motor controllers, in particular to a new energy motor controller rotary-changing wire harness sealing ring structure. Background At present, the electric control integration or the multiple-in-one of a motor for a new energy automobile in the market is a mainstream trend, the multiple-in-one motor itself needs to have an IP67 even higher protection level to the outside, and certain isolation exists between the motor and an electric control internal cavity due to temperature difference for preventing condensation and other conditions, but the requirement of the isolation is relatively low. The main stream new energy automobile comprises a motor, a controller, a rotary-change wire harness, a special connector, a screw fastener, a sealing ring and a sealing ring, wherein the rotary-change wire harness is connected between the motor and the controller for the main stream new energy automobile, the special connector is usually used for connection, the connector is fastened with a shell of the controller through the screw, and the sealing ring is arranged on the connector; however, the inventor of the present application has found that such a special connector is generally expensive, complex in assembly process and high in cost, and that for such a motor electric control two-in-one or multi-in-one integrated structure, there is a great redundancy in using the special connector under the condition that the internal isolation requirement is not high. Therefore, how to provide a new energy motor controller changes pencil sealing washer structure soon, it not only can keep apart the pencil that changes soon in the controller through this sealing washer and motor to effectively improve automatically controlled protection level, simple structure, assembly are convenient moreover, can effectively reduce cost, have become the technical problem that the technical skill of the technical skill needs to solve in the art urgently. Disclosure of utility model The utility model aims to provide a new energy motor controller rotary-changing wire harness sealing ring structure which has simple and compact overall structure and high assembly efficiency, and meanwhile, the production cost is effectively reduced, the waterproof grade is also reliable, and therefore, the quality and the reliability of products are greatly improved. In order to achieve the above purpose, the utility model adopts the following technical scheme: The novel energy motor controller rotary-change wire harness sealing ring structure comprises a sealing ring body, wherein the sealing ring body is cylindrical, a plurality of wire passing round holes are formed in the middle of the sealing ring body, and a plurality of first annular sealing bulges are formed in the wire passing round holes; One end of the sealing ring body is provided with a limiting step with the outer diameter larger than that of the sealing surface, the other end of the sealing ring body is provided with a limiting boss with the outer diameter larger than that of the sealing surface, the limiting boss is provided with a guiding inclination angle, the maximum outer diameter of the limiting boss is smaller than that of the limiting step, and the limiting boss is provided with a plurality of vertical grooves.
