Description

TECHNICAL FIELD

[0001] The utility model relates to motor technology field especially is a kind of for the wiring box of quick disassembly and assembly of motor cable. BACKGROUND

[0002] At present, the outgoing hole of the existing motor wiring box is usually directly drilled on the wiring box, and the outgoing screw sleeve is directly installed on the outgoing hole, and the motor power line is inserted into the motor wiring box from the outgoing screw sleeve, and then the screw sleeve locking nut is tightened to fix the cable.

[0003] Since the cable specification is configured according to the motor load current size, there are many base size specifications, so the wiring box screw hole size specification is also many, therefore, the motor manufacturing enterprise needs to produce more specifications of wiring box to meet the requirements of different cable specifications, which is not convenient for production and inventory management. SUMMARY

[0004] In view of the defects in the prior art, the technical problem to be solved by the utility model is to provide a wiring box for quick disassembly and assembly of motor cable which can adapt to multiple specifications of cable.

[0005] In order to solve the above technical problem, the utility model provides a wiring box for quick disassembly and assembly of motor cable, which comprises a box seat and a box cover, characterized in that: a plurality of movable screw plates are further included.

[0006] The box seat is provided with an outgoing port on the outgoing side wall, and a plurality of positioning studs for fixing the movable screw plates are arranged on the side wall, and each movable screw plate is provided with a positioning hole for inserting the positioning studs on the outgoing side wall of the box seat.

[0007] The movable screw plate is provided with a cable through hole, and a cable screw sleeve is arranged in the cable through hole portion and threadedly connected with the movable screw plate, the cable screw sleeve is provided with a screw hole, and the screw hole diameters of the cable screw sleeves of each movable screw plate are different, and the plate surface of the movable screw plate towards the box seat is attached with a sealing gasket.

[0008] The wiring box for quick disassembly and assembly of motor cable provided by the utility model can adapt to corresponding cable specifications by replacing the corresponding movable screw plate, without replacing the wiring box, so that a single type of wiring box can adapt to multiple specifications of cable, which is convenient for production and inventory management. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 is the structure diagram of the wiring box for quick disassembly and assembly of motor cable of the utility model embodiment;

[0010] Fig. 2 This is a left-side cross-sectional view of a junction box for quick assembly and disassembly of motor cables according to an embodiment of this utility model. Detailed Implementation

[0011] The embodiments of this utility model are described in further detail below with reference to the accompanying drawings. However, these embodiments are not intended to limit this utility model. Any similar structures or variations thereof that adopt this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and.

[0012] like Figs. 1-2 As shown in the figure, the junction box for quick assembly and disassembly of motor cables provided by this utility model embodiment includes a box base 1, a box cover 2, and multiple movable screw plates 3 (only one is shown in the figure).

[0013] The box base 1 has a cable outlet on the cable outlet side box wall, and the side box wall is provided with a plurality of positioning studs 31 for fixing the movable screw plate 3. Each movable screw plate 3 has a positioning hole for the positioning studs 31 on the cable outlet side box wall to be inserted. When the movable screw plate 3 is installed on the cable outlet side box wall of the box base through the cooperation of the positioning studs 31 and the positioning holes, the movable screw plate 3 covers the cable outlet of the cable outlet side box wall of the box base.

[0014] The movable screw plate 3 has a cable through hole, and a cable sleeve 32 that is threaded with the movable screw plate is provided in the cable through hole. The cable sleeve 32 has a screw hole, and the screw hole diameter of the cable sleeve of each movable screw plate 32 is different. A sealing gasket 33 is attached to the mating surface of the movable screw plate 3 facing the box seat 1.

[0015] When using the junction box provided in this embodiment, a suitable cable can be selected according to the motor load current. Then, a movable screw plate with a matching screw hole diameter can be selected according to the specifications of the selected cable. After removing the cable sleeve from the movable screw plate, it is placed on the cable. The cable sleeve is then reinstalled on the movable screw plate to complete the assembly of the cable and the movable screw plate. The cable is then passed through the outlet on the outlet side of the junction box wall into the junction box base. The movable screw plate is installed on the outlet side of the junction box base through the cooperation of the positioning stud 31 and the positioning hole, and is fixed with a nut. Cable wiring can then be performed inside the junction box. When replacing the cable, the movable screw plate 3 can be removed to replace the cable and its movable screw plate with other specifications.
