Problems solved by technology
[0002] The scroll compressors currently on the market cannot be placed in a closed environment with protective conditions due to their large size. The wiring structure connected to the scroll compressor is prone to failure problems without protection. Rainwater entered the terminal and caused the terminal to burn, which led to the failure of the scroll compressor
On the other hand, as the speed and power of the scroll compressor continue to increase, the vibration continues to increase. The existing M5 terminal connection bolts and the corresponding terminal connection plates and terminals can no longer meet the high vibration conditions of the scroll compressor. Under the use of the environment, the bolts are frequently loosened due to insufficient tightening force of the terminal connection bolts, which leads to the ignition failure of the scroll compressor

The invention provides a wiring structure for pressure-bearing equipment. The wiring structure comprises a pressure-bearing equipment shell, a protective cover, a binding post, a power line, a cover plate and a terminal connecting plate. The cover plate is blocked on the protective cover and is connected with the protective cover to form a protective box with a wiring cavity inside; the protectivecover is welded to the outer wall of the pressure-bearing equipment shell, the terminal connecting plate is arranged in the protective cover, the back face of the terminal connecting plate is attached to the bottom of the protective cover, and terminal connecting positions on the terminal connecting plate correspond to outer connectors of the binding post and power line connectors of the power line in a one-to-one mode. And a power line joint of the power line, an outer joint of the binding post and the terminal connecting plate are fastened and connected through the terminal bolt, the powerline joint through hole, the outer joint through hole of the binding post and the mounting hole of the terminal connecting plate. The structure is simple in structure and easy to produce, not only meets the high-reliability requirements of water resistance, dust prevention and electric shock prevention, but also is suitable for a severe environment, the service life of core components of the pressure-bearing equipment is greatly prolonged, and the stable operation time of the pressure-bearing equipment is prolonged.
Description
technical field [0001] The invention relates to the technical fields of electromechanical refrigeration technology and pressure equipment, in particular to a wiring structure for pressure equipment, especially to a wiring structure for scroll compressors. Background technique [0002] The scroll compressors currently on the market cannot be placed in a closed environment with protective conditions due to their large size. The wiring structure connected to the scroll compressor is prone to failure problems without protection. Rainwater entered the terminal and caused the terminal to burn, which led to the failure of the scroll compressor. On the other hand, as the speed and power of the scroll compressor continue to increase, the vibration continues to increase. The existing M5 terminal connection bolts and the corresponding terminal connection plates and terminals can no longer meet the high vibration conditions of the scroll compressor.
