Abstract
The utility model discloses a terminal box assembly of a motor, which comprises a terminal box, a terminal box installation plate and a terminal box installation seat. The terminal box installation seat is fixedly arranged on the outer surface of the casing of the motor. The terminal box installation plate is fixedly arranged on the terminal box installation seat. A first lead wire hole is arranged on the terminal box installation seat. The terminal box assembly is characterized in that an inner hole is arranged on the terminal box installation plate; a protective cover is arranged inside the inner hole; the terminal box is pressed on the protective cover and fixedly connected with the terminal box installation plate; a second lead wire hole is arranged on the terminal box; a third lead wire hole is arranged on the protective cover; and the dimension of the third lead wire hole matches the thickness of a motor winding lead wire. By arranging the protective cover on the terminal box installation plate and further arranging the third lead wire hole located on the protective cover and having a dimension matching the thickness of the motor winding lead wire, the terminal box assembly can well prevent small components or foreign matters from falling in the motor and damaging the motor. The reliable running of the motor is guaranteed. Furthermore, the terminal box assembly has a simple structure and is convenient to manufacture and install.
Description
Technical field
The utility model relates to a kind of structure of motor component, relates in particular to a kind of junction box assembly of motor.
Background technology
As everyone knows, the general larger motor of electric current can arrange a terminal box usually in the place that the lead-in wire of motor winding is drawn, and with the lead-in wire of motor winding, is connected used for the external cord of outside motor.And due to same structure, the desired size of current of motor client of volume has difference, by electromagnetism, calculate and press the size requirements of electric current, make the thickness of selecting the motor winding leads also different, and for the wire hole that makes motor case can be general to the different lead-in wire of thickness with the fairlead on terminal box, that the wire hole of motor case and the fairlead on terminal box are made to the size that applicable thick lead-in wire can loosely pass through at present, but for ligament, itself and wire hole, space between fairlead is too large, when carrying out the terminal box assembling, easily some findings such as primary screw and so on are fallen into to the wire hole of casing and entered motor internal, cause the motor that need to again dismantle and assemble, the finding that taking-up falls into, and then ressemble, if, and finding is not found while falling into, can causes a phenomenon occurring sweeping when motor moves and damage motor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly to be avoided finding or foreign matter to fall into motor internal and damages the junction box assembly of the motor of motor.
The utility model solves the problems of the technologies described above the technical scheme adopted: a kind of junction box assembly of motor, comprise terminal box, wiring box mounting board and terminal box mount pad, described terminal box mount pad is fixedly mounted on the outer surface of motor case, described wiring box mounting board is fixedly mounted on described terminal box mount pad, on described terminal box mount pad, be provided with the first fairlead, on described wiring box mounting board, be provided with endoporus, in described endoporus, be provided with protective jacket, described terminal box is pressed on described protective jacket and with described wiring box mounting board and is fixedly connected with, on described terminal box, be provided with the second fairlead, on described protective jacket, be provided with the 3rd fairlead, the thickness of the size of described the 3rd fairlead and motor winding leads is suitable.
The material of described protective jacket is the soft macromolecular material of heatproof.
The thickness of described protective jacket is slightly larger than the thickness of described wiring box mounting board.
The underside shape of described terminal box mount pad and the external surface shape of motor case are suitable and be close on the outer surface that is fixed on motor case.
The external diameter of described protective jacket is greater than respectively the aperture of described the first fairlead and the aperture of described the second fairlead.
Compared with prior art, the utility model has the advantages that owing on wiring box mounting board, being provided with protective jacket, and on protective jacket, the thickness of the size of the 3rd fairlead and motor winding leads is suitable, can prevent well that some findings or foreign matter from falling into motor internal and damaging motor, and because the material of protective jacket adopts the soft macromolecular material of heatproof, avoid the motor winding leads directly with the contact friction of other steel components, to damage, guaranteed the reliability service of motor; In addition, this junction box assembly is simple in structure, manufacture is easy for installation.
The accompanying drawing explanation
Fig. 1 is that the utility model is arranged on the structural representation on motor case;
Fig. 2 is cutaway view of the present utility model.
Embodiment
