Low voltage connecting terminal of refrigeration motor

Abstract

The invention provides a low voltage connecting terminal of a refrigeration motor. The low voltage connecting terminal comprises a conducting rod, insulation pipes sleeved on the conducting rod and an iron shell which is fixedly arranged on the outer walls of the insulation pipes and fixed with an external mechanism. Two end portions of the conducting rod are respectively exposed out of two end portions of the insulation pipes, and are respectively connected with an outside power supply and a motor. The insulation pipes comprise a first insulation pipe and a second insulation pipe which are arranged along the length direction of the conducting pipe. Opposite ends of the first insulation pipe and the second insulation pipe are respectively provided with a limit portion. The limit portions are clamped in the iron shell. A sealing ring is arranged between the first insulation pipe and the second insulation pipe, and sleeved on the conducting rod. Compared with the prior art, the low voltage connecting terminal of the refrigeration motor has better sealing performance and compression resistance.

Description

technical field [0001] The invention relates to a connection terminal used for a low-voltage motor dedicated to closed-type refrigeration and compression with an operating voltage below 1000V. Background technique [0002] Since the closed motor for refrigeration compression works in the closed environment of the refrigeration compressor system, it is directly in contact with the refrigerant, refrigerating machine oil and other substances in the refrigeration system, so the connection terminals between the motor and the external power supply are required to have good refrigeration resistance. In addition to the performance of the agent, it must also have excellent sealing performance and pressure resistance, but there is no motor connection terminal for the hermetic refrigeration compressor of the low-pressure refrigeration motor with this performance in the prior art. Contents of the invention [0003] In order to overcome the defects of the prior art, the object of the p...

[0002] Since the closed motor for refrigeration compression works in the closed environment of the refrigeration compressor system, it is directly in contact with the refrigerant, refrigerating machine oil and other substances in the refrigeration system, so the connection terminals between the motor and the external power supply are required to have good refrigeration resistance. At the same time, it must have excellent sealing performance and pressure resistance performance, but there is no such performance in the prior art as a motor terminal for a hermetic refrigeration compressor used in a low-pressure refrigeration motor.
