Problems solved by technology

[0002] The power lead wire of the motor passes through the casing, and a sealing ring is usually provided at the perforation of the casing to seal and prevent water or dust impurities from entering, but the existing sealing ring is usually flat or retracted for a certain distance from the outer end surface of the casing In this way, if the motor is soaked by raindrops, especially when the motor is vibrating, the sealing ring will be easily deformed, and there will be a gap between the sealing ring and the power lead-out line, and rainwater will enter the casing

Embodiment Construction

[0013] Such as figure 1 with figure 2 As shown, it is the structure of the motor power supply lead-out line of the present invention, including a casing 1 and a power supply lead-out line 2 passing through the hole in the casing. A sealing ring 3 is provided between the power supply lead-out line and the casing perforation, and the sealing ring 3 The outer port is provided with an extension section 31 protruding from the casing, and the port 32 of the extension section is a cone structure, and the length of the extension section is 5-10 cm. When multiple power lead wires pass through the same case, if image 3 , The through holes in the sealing ring are composed of several independent single-line perforations 33 .

Abstract

The invention discloses a perforating structure of a motor power leading-out wire, comprising a shell and a power leading-out wire, wherein the power leading-out wire perforates through a shell perforating hole, a seal ring is arranged between the power leading-out wire and the shell perforating hole, a through hole for allowing the power leading-out wire to pass is arranged in the seal ring, an outer port of the seal ring is provided with an extension section which extends out of the shell, and a port of the extension section has a taper hole structure. In the invention, the outer port of the seal ring is provided with the extension section which extends out of the shell, the port of the extension section has the taper hole structure, and thus, the seal performance between the power leading-out wire and the seal ring can be reinforced, thereby better protecting a motor from rain.

Description

technical field [0001] The invention relates to a threading structure for a motor power lead wire. technical background [0002] The power lead wire of the motor passes through the casing, and a sealing ring is usually provided at the perforation of the casing to seal and prevent water or dust impurities from entering, but the existing sealing ring is usually flat or retracted for a certain distance from the outer end surface of the casing In this way, if the motor is soaked by rainwater, especially the sealing ring is easily deformed during the vibration of the motor, there will be a gap between the sealing ring and the power lead-out line, and rainwater will enter the casing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a threading structure for the lead wire of the motor power supply, which can improve the sealing performance between the lead wire of the motor power supply and the end cover, so as to better...
