Problems solved by technology

[0002] At present, the lead wire is a cable that connects the inside and outside of the motor to provide electric energy to the motor. The lead wire is a current-carrying conductor, so it needs to be protected. This requirement is particularly important for traction motors. For general lead wire protection devices, see figure 1 shown, from figure 1 It is not difficult to see that a layer of protection is adopted for the lead wires, that is, the shell and the cover plate. For traction motors that often have to go through rain, snow, haze, and sand and dust, such protection is not sufficient, and it may still cause damage. Accidents that pose a threat to the safety of passengers

Abstract

The invention discloses a lead protection device. The device includes an inner protection mechanism arranged outside a wire holder group, the wire holder group includes at least one wire holder, the upper part of the wire holder is a supply lead wiring part, the upper side of the power lead wiring part is a supply lead wiring area, the inner protection mechanism has an insulator used for accommodating the wire holder group and an inner shell which covers the upper side of the supply lead wiring area, the upper part of the insulator is provided with a supply lead protection surrounding edge around the supply lead wiring area, and the supply lead protection surrounding edge is provided with a wiring port corresponding to a supply lead opening, so that a supply lead is accessed to the wire holder. The lead protection device provided by the invention can improve the protection level of a motor lead, thereby enhancing reliability of motor operation.

Description

technical field [0001] The invention relates to a wire protection device. Background technique [0002] At present, the lead wire is a cable that connects the inside and outside of the motor to provide electric energy to the motor. The lead wire is a current-carrying conductor, so it needs to be protected. This requirement is particularly important for traction motors. For general lead wire protection devices, see figure 1 shown, from figure 1 It is not difficult to see that a layer of protection is adopted for the lead wires, that is, the shell and the cover plate. For traction motors that often have to go through rain, snow, haze, and sand and dust, such protection is not sufficient, and it may still cause damage. The accident poses a threat to the safety of passengers. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a lead wire protection device, which can improve th...
