Abstract
The utility model relates to a motor junction box structure, which is characterized in that a first gland bush is arranged on a stand, wherein a junction box seat is arranged on the first gland bush,and the first gland bush is connected with the junction box seat through a third bolt; the junction box seat is provided with a second gland bush, and the second gland bush is connected with a junction box cover through a first bolt; a connecting plate is connected with the stand through a second bolt; and a grounding plate is connected with the junction box seat or the stand through a spring gasket ring and a fourth bolt (copper), and a threaded sleeve is connected with the junction box seat through threads. The motor junction box structure has simple, compact and reasonable structure; on thebasis that the appearance and the internal size of the uniformly-designed junction box of the series-Y2 motor, the appearance and the size of the connecting plate is re-changed, so that the mechanical strength and the electric appliance performance requirement of the connecting plate can be ensured; and corresponding grounding position is remained inside the series-Y2 motor junction box so as tosatisfy the requirement of the customers on the grounding position.
Description
Technical field
The utility model relates to a kind of junction box structure of electrical machine, and specifically the new arrangement plate of height of center Y2-250～280 among the JB/T8680-2008 belongs to field of mechanical technique.
Background technology
At present, along with the development of China's science and technology and industrial situation, the production of motor and export order are more and more.Connection box for motor is connected to form by junction box seat, connector cover, motor terminal block, sealing gasket, nut, bolt, screw etc. usually.And each country is also inequality to the standard and the instructions for use of corresponding motor, so the prior motor terminal block is difficult to meet domestic standard, can satisfy export requirement again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, can vacate corresponding earthing position in Y2 serial motors terminal box thereby provide a kind of, satisfies client's location requirements for grounding; And can guarantee the mechanical strength of terminal block and the junction box structure of electrical machine that electric property requires.
According to the technical scheme that the utility model provides, a kind of junction box structure of electrical machine adopts and be provided with first sealing gasket on support, and first sealing gasket is provided with junction box seat, and first sealing gasket, junction box seat are by the 3rd screw attachment; Junction box seat is provided with second sealing gasket, and second sealing gasket, connector cover are by first screw attachment; Terminal block is connected with support by second screw; The ground connection board is connected on junction box seat or the support by spring washer and the 4th screw (copper), and swivel nut and junction box seat are by being threaded.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; On the basis of profile that does not change the unified terminal box that designs of Y2 serial motors and inside dimension, change the profile and the size of terminal block again, can guarantee the mechanical strength and the electric property requirement of terminal block; Can in Y2 serial motors terminal box, vacate corresponding earthing position, satisfy client's location requirements for grounding
