Electromagnetic part of separation-falling connector

Abstract

The invention relates to a novel electromagnetic part having a large suction force. The novel electromagnetic part comprises a fixed armature 1, a winding shell 2, an electromagnetic enameled wire 3,an electromagnetic support 4 and a moving armature 5, and the shape of a suction surface of the fixed armature and the moving armature in the electromagnetic part is of a T-shaped circumferential stepped conical structure. By such improvement of the electromagnetic part, the magnetic flux during the suction process is improved, the initial electromagnetic suction force is improved, the contact length of the moving armature and the winding shell is increased, the magnetic flux loss during the moving process is reduced, the reduction quantity of the electromagnetic suction force is reduced, theelectromagnetic suction force is stable, the reduction quantity is low, and the electromagnetic separation reliability is improved.

Description

technical field [0001] The invention belongs to the electromagnetic attraction technology, and in particular relates to a novel electromagnetic component with large attraction force. Background technique [0002] Electromagnetic components are widely used in separation and fall-off connectors. When power is supplied to the internal electromagnetic components of the connector, the electromagnetic mechanism works to unlock the internal locking components of the connector and realize the automatic separation of the connector. With the development of weapon models, various requirements are put forward for the separation and separation connectors, such as requiring the product shape to be unchanged to improve the reliability of electromagnetic separation or to increase the speed of electrical separation. Therefore, it is necessary to improve the electromagnetic attraction of electromagnetic components while maintaining the same shape. work together to achieve the above requiremen...

For the structure of existing electromagnetic components, see figure 1 , mainly composed of fixed armature 1, winding shell 2, electromagnetic enameled wire 3, electromagnetic bracket 4 and moving armature 5, the fixed armature 1 and the moving armature 5 are both circular cones, and the suction of the suction surface is greatly affected by external interference , by simulating the electromagnetic attraction force of this structure, the results are as follows figure 2 As shown, the initial electromagnetic attraction force of the electromagnetic component is small, and the electromagnetic attraction force first increases and then decreases rapidly with the movement of the displacement. This decline process will affect the reliability of the electromagnetic separation of the connector
