Abstract
The invention relates to a junction box structure of an electrical machine, wherein a base is provided with a first sealing gasket, the first sealing gasket is provided with a junction box base, and the first sealing gasket and the junction box base connected through a third screw; the junction box base is provided with a second sealing gasket, and the second sealing gasket and the junction box base connected through a first screw; a junction plate is connected with the base through a second screw; and an earthing tablet is connected on the junction box base or the base through a spring washer and a fourth screw (copper), and a barrel is connected with the junction box base through thread. The junction box structure of of the invention has simple, compact and rational structure, and the appearance and size of the junction plate are changed again on the basis that the appearance and inner size of the junction box uniformly designed for the Y2 serial electrical machine are not changed, and the demands of mechanical strength and electric performance are ensured; and corresponding earthing position is remained in the junction box of the Y2 serial electrical machine to meet the requirement of earthing position of the users.
Description
Technical field
The present invention relates to a kind of junction box structure of electrical machine, 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 objective of the invention is to overcome above-mentioned weak point, can in Y2 serial motors terminal box, vacate corresponding earthing position, satisfy client's location requirements for grounding thereby provide a kind of; And can guarantee the mechanical strength of terminal block and the junction box structure of electrical machine that electric property requires.
According to technical scheme provided by the invention, 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 present invention has the following advantages:
The present invention 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
