DESCRIPTION 2017100843 26 Jun2017
LONG-SERVICE-LIFE PROTECTION STRUCTURE FOR A LEADING-OUT WIRE OF A MOTOR
Technical Field of the Invention
The present invention relates to a long-service-life protection structure for a leading-out wire of a motor.
Background of the Invention
In an existing motor, a wire hole is usually formed on the side wall of the motor end cover or the side wall of the motor shell. A rubber sleeve is stuffed into the wire hole for water-proof sealing. The leading-out wire extends out of the motor from the through hole on the rubber sleeve.Since the rubber sleeve is easily separated from the motor, there is a risk of water penetration into the motor due to the insufficient sealing. Moreover, the leading-out wire may be folded or scratched because of no protection, and as a result, the service life of the leading-out wire is influenced.
Summary of the Invention
An objective of the present invention is to provide a long-service-life protection structure for a leading-out wire of a motor.
The present invention employs the following technical solution. A protection structure for a leading-out wire of a motor is provided; a positioning notch having an opening facing a motor shell and running through an axial end face of a motor end cover is formed on a side wall of the motor end cover, or a positioning notch having an opening facing a motor end cover and running through an axial end face of a motor shell is formed on a side wall of the motor shell; the positioning notch is of an open structure in which the opening is gradually enlarged; a wire grommet is fitted at the positioning notch, and a 1 through hole for allowing the leading-out wire to pass therethrough is formed on the wire grommet; the wire grommet consists of a positioning portion, an outer limiting portion located on an outer side of the positioning portion, and an inner limiting portion located on an inner side of the positioning portion; an outer edge of the positioning portion and the positioning notch are the same in shape; part or all of the outer edge of the outer limiting portion is located on an outer side of the outer edge of the positioning portion, and part or all of the outer edge of the inner limiting portion is located on an inner side of the outer edge of the positioning portion; and the wire grommet is coordinated with the motor so that the positioning portion is located within the positioning notch and a side wall of the motor is located between the outer limiting portion and the inner limiting portion;the axial length of the outer limiting portion is greater than that of the positioning portion; when the positioning notch is arranged on the motor end cover, the wire grommet, the motor shell and the motor end cover are fixed together, with the outer limiting portion covering the positioning notch, and with one end of the outer limiting portion extends to the outer side of the side wall of the motor shell and closely fitting the side wall of the motor shell; when the positioning notch is arranged on the motor shell, the wire grommet, the motor shell and the motor end cover are fixed together, with the outer limiting portion covering the positioning notch, and with one end of the outer limiting portion extends to the outer side of the side wall of the motor end cover and closely fitting the side wall of the motor end cover. 2017100843 26 Jun2017
The present invention exhibits better sealing effect and firmer assembly, and can protect the leading-out wire of the motor to increase the service life of the leading-out wire of the motor.

As shown in Fig. 1 to Fig. 7, the present invention provides a protection structure for a leading-out wire of a motor; a positioning notch 3 having an opening facing a motor shell 2 and running through an axial end face of a motor end cover 1 is formed on a side wall of the motor end cover 1: the positioning notch 3 is of an open structure in which the opening is gradually enlarged, and the positioning notch 3 is of a U-shaped structure in which the opening is gradually enlarged; and a wire grommet 4 is fitted at the positioning notch 3.
As shown in Fig. 2 and Fig. 3, a via hole 41 for allowing the leading-out wire to pass therethrough is formed on the wire grommet 4; and the wire grommet consists of a positioning portion 42, an outer limiting portion 43 located on an outer side of the positioning portion 42, a first wire conduit 44 located on the outer side of the outer limiting portion 43, an inner limiting portion 45 located on an inner side of the positioning portion 42, and a second wire conduit 46 located on the inner side of the inner limiting portion 45. 3
As shown in Fig. 6 and Fig. 7, an outer edge of the positioning portion 42 and the positioning notch 43 are the same in shape; all of the outer edge of the outer limiting portion 43 is located on an outer side of the outer edge of the positioning portion 42, and part of the outer edge of the inner limiting portion 45 is located on an inner side of the outer edge of the positioning portion 42; and the wire grommet 4 is coordinated with the motor so that the positioning portion 42 is located within the positioning notch 3 and a side wall of the motor is located between the outer limiting portion 43 and the inner limiting portion 45. 2017100843 26 Jun2017
As shown in Fig. 1, Fig. 6 and Fig. 7, the wire grommet 4 is coordinated with the motor so that the first wire conduit 44 is located on an outer side of the motor and the second wire conduit 46 is located on an inner side of the motor; the first wire conduit 44 is of an elbow structure; and axes of via holes for the outer limiting portion 43, the positioning portions 42, the inner limiting portion 45 and the second wire conduit 46 are arranged perpendicularly to an axis of the motor.
As shown in Fig. 2, Fig. 3, Fig. 6 and Fig. 7, the positioning portion 42 of the wire grommet 4 is fitted within the positioning notch 3 so that part of the positioning portion is located on the axial outer side of the positioning notch 3; and the motor end cover 1 is fixed to the motor shell 2 so that the positioning portion 42 is tightly compressed within the positioning notch 3.Rabbet structures which are fitted with each other are formed on an axial end face of the motor end cover 1 and an axial end face of the motor shell 2; a concave rabbet structure is provided on the motor end cover 1 and a convex rabbet structure is provided on the motor shell 2; an axial end face for an outer edge 11 and an axial end face for an inner edge 12 are provided on the axial end face of the motor end cover 1, and the axial position of the axial end face for the outer edge 11 is located on the outer side of the axial position of the axial end face of the inner edge 12.The positioning portion 42 includes a first positioning portion 421 and a second positioning portion 422, and the second positioning portion 422 is located on the radial inner side of the first positioning 4 portion 421; when the positioning portion 42 is fitted within the positioning notch 3, part of the first positioning portion 421 is located on the axial outer side of the axial end face for the outer edge 11, and part of the second positioning portion 422 is located on the axial outer side of the axial end face for the inner edge 12; and the axial position of the axial end face for the outer edge 11 is located on the axial outer side of the second positioning portion 422. 2017100843 26 Jun2017
