Embodiment Construction

[0028] First of all, it should be explained that the present invention not only provides a push-pull electromagnet, but also provides a production and preparation method of the electromagnet. As a specific embodiment of a push-pull electromagnet of the present invention, as Figure 1 to Figure 3 As shown, it includes a housing 1 , a rear cover 2 , a moving iron core 3 , a winding bobbin 4 , a coil 5 and an electrical connector socket 6 . One end of the housing 1 is provided with a first groove 11 along the central axis for accommodating the bobbin 4 and the coil 5, and the other end of the housing 1 is provided with a first groove 11 communicating with the first groove 11 along the central axis. The through hole 12 is used for the moving iron core 3 to pass therethrough. The winding frame 4 is placed in the first groove 11 of the housing 1 and packaged by fixed connection with the housing 1 through the rear cover 2. The fixing method can be various ways such as screws and bol...

Abstract

The invention discloses a wide-temperature-range large-suction pushing-pulling electromagnet and a manufacturing method thereof. The electromagnet comprises a shell, a rear sealing cover, a movable iron core, a winding framework, a coil and an electric connector socket, the winding framework is positioned in a first groove in the shell and fixedly connected with the shell through the rear sealing cover for sealing, and the coil is wound in a winding groove of the winding framework and enables two poles of the coil to penetrate the shell to be electrically connected with the electric connector socket. One end of the movable iron core is positioned in a magnetic core hole of the winding framework and connected with the rear sealing cover through a resetting spring while the other end of the same penetrates a first through hole in the shell and extends to the outer side of the shell, the shell, the rear sealing cover and the movable iron core are made of electromagnetic pure iron, and the winding framework is made of aluminum bronze. The electromagnet has the advantages of simple structure, small size, large suction and flexibility, and the electromagnet can work stably in an environment with a wide temperature range and rain and other environments. The manufacturing method has the advantages of simple process, convenience in assembly and high working efficiency.

Description

technical field [0001] The invention relates to an electric control device, in particular to a push-pull electromagnet applicable to a relatively large temperature range and capable of generating relatively large suction force, and a preparation method of the electromagnet. Background technique [0002] As an electronic control component, the electromagnet is widely used in the fields of industrial and agricultural production and scientific and technological research and development. However, the existing electromagnets generally have the problems of large volume, poor adaptability, and easy failure under harsh conditions, and often cannot be used in working conditions with special requirements on the environment. For example, in the field of launch vehicles, since the launch devices are all outdoors and need to go through a long time, for some launch devices, electromagnets are used as the action drive components of their electric mechanisms, and the electromagnets are requ...
