Electromagnet coil framework

Abstract

The invention discloses an electromagnet coil framework which comprises a coil framework body (1) with a central hole, wherein the two ends of the coil framework body (1) are respectively provided with radial convex rings (1.1); and the outer side wall of each radial convex ring (1.1) is provided with at least one radial annular groove (1.1.1). According to the electromagnet coil framework, the probability of entering water into the coil can be reduced, and the protection level is high.

Description

technical field [0001] The invention relates to the technical field of electromagnets, in particular to an electromagnet coil skeleton suitable for various liquid valves. Background technique [0002] The electromagnet mainly includes three parts: a coil, an iron core and an armature. The iron core is generally stationary, and the coil is mounted on the iron core. When the coil is energized, the iron core and the armature are magnetized and become two magnets with opposite polarities, thereby causing the armature to reciprocate. [0003] The electromagnet coil frame is used for winding coils, and the electromagnet coil frame includes a coil frame body with a central hole, and two ends of the coil frame body are respectively provided with radial protruding rings. After the electromagnet is assembled, the radial protruding rings at both ends of the coil bobbin are respectively tightly fitted and sealed with the electromagnet housing. There are sealing rings. There is followi...

Problems solved by technology

[0004] 1. Solenoid valves are widely used in various valves in the hydraulic system of mechanical equipment. After long-term use, when the sealing ring is aging, the impurity water in the complex environment will still flow into the coil from the gap between the skeleton and the shell. Water will directly cause a short circuit of the coil, so that the entire hydraulic system will be paralyzed, and its protection level is low
