Electromagnet coil skeleton

Abstract

The invention discloses an electromagnet coil skeleton, including a coil skeleton body, the coil skeleton main body has a cylindrical structure, the outer surface of the coil skeleton main body is longitudinally uniformly and fixedly connected with a plurality of strips, a plurality of winding openings are uniformly arranged on the surfaces of the plurality of the strips, the lower surface of thecoil frame main body is fixedly connected with a bottom connecting plate, the side walls of the bottom connecting plate are fixedly connected with two first fixing plates, first water drain tanks arerespectively arranged on the inner side walls of the two first fixing plates far away from the bottom connecting plate, and each of the upper surfaces of the two first fixing plates are fixedly connected with a first waterproof plate. The invention reduces the entry of water, effectively avoids the short circuit of the coil, avoids the paralysis of the whole hydraulic system, improves the protection level, avoids the clutter of the electromagnet coil, simplifies the winding, saves the space, avoids the accidents easily occurring when the whole equipment is in use, and reduces the safety hiddendanger.

Description

technical field [0001] The invention relates to the technical field of coil bobbins, in particular to an electromagnet coil bobbin. Background technique [0002] The electromagnet mainly includes three parts: the coil, the iron core and the armature. The iron core is generally stationary, and the coil is installed on the iron core. When the coil is energized, the iron core and the armature are magnetized and become two magnets with opposite polarities, so that the armature reciprocates. The electromagnet coil bobbin is used to wind the coil. The electromagnet coil bobbin includes a coil bobbin body with a central hole. The two ends of the coil bobbin body are respectively provided with radial convex rings. After the electromagnet is assembled, the two ends of the coil bobbin are radially The protruding rings are closely fitted and sealed with the electromagnet casing respectively, and the sealing means that sealing rings are respectively arranged between the end faces of the...

AI Technical Summary

Problems solved by technology

[0003] There are many shortcomings in the existing solenoid coil skeleton. Solenoid valves are widely used in various valves in the hydraulic system of mechanical equipment. The gap between them flows into the coil, impurity water will directly cause the short circuit of the coil, so that the entire hydraulic system is paralyzed, and its protection level is low, and the existing electromagnet coil skeleton winding is troublesome and easy to mess up, making the whole equipment in use. Accidents are prone to occur at times, and there are potential safety hazards
