Soft starter power connector

Abstract

The invention discloses a soft starter power connector, which comprises an insulating seat and connector main bodies. The three groups of connector main bodies are respectively connected with a three-phase power supply, and a power supply connecting terminal and a plurality of soft starter connecting terminals are integrally formed on each connector main body; three groups of insulating grooves are sequentially formed in the insulating seat; the three groups of connector main bodies are respectively inserted into the three groups of insulating grooves; the free ends, extending outwards, of thepower supply connecting terminals of the three groups of connector main bodies are respectively in conductive connection with the three-phase output terminals of the three-phase power supply; and thefree ends, extending outwards, of the soft starter connecting terminals of the three groups of connector main bodies are electrically connected with the three-phase electric terminals of the soft starter respectively. The soft starter power connector disclosed by the invention is reliable and stable in conductive connection, and avoids the technical problems of misconnection, short circuit and the like; meanwhile, one group of power connectors can be matched with synchronous power connection of a plurality of soft starters, so that the space configured for the soft starters in the control cabinet is greatly reduced, and the miniaturization design of the control cabinet is facilitated.

Description

technical field [0001] The invention relates to the technical field of soft starters, in particular to a soft starter power connector. Background technique [0002] The soft starter is a motor control device that integrates motor soft start, soft stop, light load energy saving and multiple protection functions. Its main components are three-phase parallel gates and its electronic control circuit. Using a soft starter can control the voltage of the motor so that it gradually increases during the starting process, and naturally controls the starting current so that the motor can start smoothly and the mechanical and electrical stresses are minimized. [0003] The power terminal of the soft starter and the three-phase power supply are connected based on the conductive connection of the power connector to receive the power supply of the three-phase power supply. At present, the power terminal of the soft starter is connected to the power supply terminal of the three-phase power...

Problems solved by technology

However, according to actual use needs, when the control system needs to be equipped with multiple soft starters (more than 3), additional space needs to be configured in the control cabinet to house the power cords of the soft starters, and 3N power supplies need to be configured corresponding to the number of soft starters wires (N is the number of soft starters), the more power wires, the greater the wiring pressure. At the same time, there are technical problems that the soft starter cannot work normally or even burn out due to problems such as wrong connection and short connection of power wires.
