Self-hold electromagnet of built-in bi-directional position detection

Abstract

The invention relates to a self-hold electromagnet of built-in bi-directional position detection. The self-hold electromagnet of the built-in bi-directional position detection comprises an output shaft, a piston, an upper end cover, a lower end cover, a guide barrel, magnetic steel, a coil former, a coil and a case. The upper end of the output shaft is vertically installed on the upper end cover in a penetrating mode. The lower end of the output shaft is coaxially connected with the piston. The lower end cover is located at the bottom of the piston. The outer side of the piston is coaxially sleeved with the guide barrel, the magnetic steel, the coil former, the coil and the case in sequence. The magnetic steel comprises upper magnetic steel and lower magnetic steel which are vertically arranged and opposite in polarity. An upper insulation mat and an upper contact switch are embedded in the upper end cover. A lower insulation mat and a lower contact switch are embedded in the lower end cover. The self-hold electromagnet of the built-in bi-directional position detection is reasonable in design, scientific in structure and convenient to use. According to the self-hold electromagnet of the built-in bi-directional position detection, two position statuses of the electromagnet are both shown through continuity signals, the self-hold force is also increased, the switching time is shortened, and the usage requirements of fusing devices such as rocket projectiles and shells are met.

Description

technical field [0001] The invention relates to the technical field of electromagnet manufacturing, in particular to a self-holding electromagnet with built-in bidirectional position detection. Background technique [0002] In fuze devices such as rockets and artillery shells, electromagnets are usually used for mechanical limit protection and release, which requires the electromagnet to have the characteristics of bidirectional position detection, large self-holding force, and short state switching time. However, the existing The electromagnet of the latest technology cannot perform two-way position detection, that is, it cannot indicate the two position states through conduction signals. In addition, the self-holding force and switching time need to be further improved. [0003] In addition, in the existing magnetic holding electromagnet with state detection, its state detection pushes the moving reed inside the electromagnet when the armature moves, so that the moving ree...
