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.
