Abstract
The invention relates to a junction box structure of a three-phase asynchronous motor. A machine base is provided with a first seal gasket; the first seal gasket is provided with a junction box base; the machine base, the first seal gasket and the junction box base are fixed integrally through a third screw; grounding cards are fixed on the machine base or the junction box base through a fourth screw; the junction box base is provided with a second seal gasket; the second seal gasket is provided with a junction box cover; the junction box base, the second seal gasket and the junction box are fixed integrally through a first screw; a junction plate is fixed on the machine base through a second screw; and the machine base is threadedly connected with a thread nut. The junction box structure of the three-phase asynchronous motor is simple, compact and reasonable in structure; on the basis that the integrally designed appearance and internal dimension of the junction box of the Y2 series of three-phase asynchronous motor are not changed, the corresponding grounding position can be vacated in the Y2 series motor junction box only through changing the appearance and the dimension of the junction plate, and meanwhile, the mechanical intensity and electric appliance performance requirement of the junction plate can be ensured.
Description
Technical field
The present invention relates to a kind of motor connecting cartridge structure, especially a kind of threephase asynchronous junction box structure.
Background technology
Since China joined WTO, the trade contacts of home and overseas are more and more frequent, each other in the cooperation of aspects such as science and technology, industry also more and more widely.The production of threephase asynchronous and export order are also more and more, find that in long-term cooperation each country also is not quite similar to the standard and the instructions for use of corresponding motor.Connection box for motor is connected to form by junction box seat, connector cover, motor terminal block, sealing gasket, nut, bolt, screw etc. usually, can meet domestic standard but existing domestic motor terminal block is very difficult, can satisfy export requirement again.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of and can in Y2 serial motors terminal box, vacate corresponding earthing position, also can guarantee the mechanical strength of terminal block and the threephase asynchronous junction box structure that electric property requires simultaneously.
According to technical scheme provided by the invention; Said threephase asynchronous junction box structure; Comprise first screw, first sealing gasket, junction box seat, second sealing gasket, connector cover, terminal block, second screw, the 3rd screw, ground connection board, the 4th screw, swivel nut and support; On support, be provided with first sealing gasket; On first sealing gasket, be provided with junction box seat, support, first sealing gasket and junction box seat are having described ground connection board through the 4th screw through the 3rd screw one on the support or on the junction box seat; On junction box seat, be provided with second sealing gasket, on second sealing gasket, be provided with connector cover, junction box seat, second sealing gasket and connector cover are through the first screw one; On support, terminal block is arranged, on support, be bolted with swivel nut through second screw.
Said terminal block 6 adopts BMC plastics or 4220 plastics to process.
The present invention is simple in structure, compact; Rationally; On the basis of profile that does not change the unified terminal box that designs of Y2 series threephase asynchronous and inside dimension; Only, just can in Y2 serial motors terminal box, vacate corresponding earthing position, also can guarantee the mechanical strength and the electric property requirement of terminal block simultaneously through changing the profile and the size of terminal block.
