A novel motor junction box

Abstract

The invention discloses a novel motor junction box, including a chassis, the outer wall of the chassis is provided with a threaded hole, and a sealing rubber ring is adhered to the outer surface of the upper end of the chassis, a fastening bolt is arranged on the inner surface of the threaded hole on the chassis, the outer surface of the fastening bolt is provided with a main casing of the junction box, the outer surface of the front end of the main casing of the junction box is provided with a lead pipe, and the inner surface of the lead pipe is provided with a threaded pipe, the outer surface of the threaded pipe is sleeved with a circular tab, and the outer surface of one end of the circular tab is provided with a hauling rope, and the outer surface of one end of the hauling rope is fixedly connected with the lead pipe. The invention relates to a novel motor terminal box, A screw pipe, a round joint piece, a sealing rubber ring and a pressure plate are provided, which have enough good sealing property to play a moisture-proof effect, and less oxygen in the space can play a good flame-retardant effect, at the same time, the screw pipe can play a role of tightening to prevent theinternal wiring from sloshing and winding problems, thus bringing a better application prospect.

Description

technical field [0001] The invention relates to the field of junction boxes, in particular to a novel motor junction box. Background technique [0002] Usually, there are six terminals in the junction box of the motor, that is, the respective heads and tails of the three-phase windings, which are used to change the wiring mode and lead-out of the windings. For wound-type asynchronous motors, the rotor circuit leads three wires to the junction box for starting. Resistor or frequency-sensitive rheostat, the junction box must have good flame retardancy and water resistance; the existing junction box has certain disadvantages when used, it does not have good enough sealing, the moisture-proof effect is poor, and the inside of the box There is a lot of oxygen in the space, which cannot play a good flame retardant effect. At the same time, it cannot play a fastening role and cannot prevent the internal wiring from shaking and entanglement. It needs further improvement, and it has ...

At the same time, it cannot play a fastening role and cannot prevent the internal wiring from shaking and entanglement. It needs further improvement, and it has brought a certain impact in actual use. , for this purpose, we propose a new motor junction box
