Abstract
The utility model relates to a rear-mounted waterproof motor of terminal box, close the rear end cap in the motor main part rear end, its characterized in that including motor main part, fixing terminal box and the lid in motor main part: the rear end cover is a closed end cover, the rear end cover is fixed with the rear end of the motor main body through screws, and the junction box is integrally formed at one end, close to the rear end cover, of the outer wall of the motor main body. This waterproof motor of rear-mounted terminal box makes the pertinence change to the motor rear end cap on old-fashioned motor basis, and the mould is opened again, and one-time molding has simplified original overall structure, makes this product separation in the use the contact of motor inside with water, has prolonged the life of this type of motor greatly.
Description
The technical field is as follows:
the utility model relates to an explosion-proof machine technical field especially relates to a rear-mounted waterproof motor of terminal box.
Background art:
the junction box of the existing explosion-proof motor is generally of a front-mounted type, as shown in fig. 1, a junction box A is installed at the front end of a motor main body, a rear end cover B is a conventional through hole end cover, the rear end cover B is covered at the rear end of the motor main body, and then a waterproof end cover C is covered. The sealing effect of the waterproof motor is not ideal, and water seepage can occur in various sealing devices for a long time, so that the motor cannot normally work due to insulation damage, and the service life is short.
The utility model has the following contents:
to the not enough among the prior art, the utility model provides a compact structure, the volume is littleer, weight is lighter, the longer terminal box rear-mounted waterproof motor of life.
The utility model discloses a realize through following technical scheme: the utility model provides a terminal box rear-mounted waterproof motor, includes motor body, fixes terminal box and the rear end cap that covers at motor body rear end on motor body, the rear end cap is closed end cover, and the rear end cap passes through the screw to be fixed with motor body rear end, terminal box integrated into one piece is in the one end that motor body outer wall is close to the rear end cap.
In order to facilitate wiring, a through hole communicated with the inside of the junction box is formed in the motor main body shell.
In order to facilitate positioning and mounting of the rear end cover, a plurality of positioning plates are integrally formed on the outer wall of the rear end of the motor main body, and the rear end cover is fixed with the positioning plates through screws.
The utility model has the advantages that: this waterproof motor of rear-mounted terminal box makes the pertinence change to the motor rear end cap on old-fashioned motor basis, and the mould is opened again, and one-time molding has simplified original overall structure, makes this product separation in the use the contact of motor inside with water, has prolonged the life of this type of motor greatly.
Description of the drawings:
FIG. 1 is a schematic structural diagram of a motor with a front-mounted junction box in the prior art;
fig. 2 is a schematic structural view of the junction box rear-mounted waterproof motor of the present invention.
The specific implementation mode is as follows:
the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
