Moving iron unit provided with E-shaped armature and receiver comprising moving iron unit

Abstract

The invention discloses a moving iron unit provided with an E-shaped armature. The moving iron unit comprises an iron core, a magnet, a coil and the E-shaped armature, wherein the iron core is provided with a mounting port and at least two locating slots; the magnet is arranged in the mounting port; the E-shaped armature comprises a first connection part, a second connection part, a third connection part and a turning part; the first connection part, the second connection part and the third connection part are connected with the turning part respectively, thereby forming an E-shaped structure; the first connection part and the second connection part are matched with the locating slots; and the third connection part is inserted into the coil and the mounting port. The moving iron unit has the beneficial effects that the first connection part and the second connection part are matched with the locating slots, and the third connection part is inserted into the coil and the mounting port, so that the E-shaped armature can be inserted into a working position of the iron core like a drawer; a high-accuracy locating requirement is ensured; and the E-shaped armature can be assembled without any stationary fixture. Moreover, only the iron core is needed for locating in a welding process, so that subsequent automatic production is ensured.

Description

Technical field [0001] The invention relates to the field of receivers, in particular to a moving iron unit with an E-type armature and a receiver containing the same. Background technique [0002] The moving iron unit of the receiver mainly includes an iron core, a magnet, a coil and an armature. At present, in the assembly process of the receiver, a high-precision positioning fixture is required to position the armature in the center of the iron core, and the armature is in the working position of the center of the iron core. It is high-precision, it is very difficult to make and adjust the positioning fixture, and it is time-consuming and laborious. During the welding process, both the positioning fixture and the iron core need to participate in the welding process. The welding process is more complicated and the production efficiency is low. [0003] Therefore, there is an urgent need for a moving iron unit of a receiver in which the armature can be installed in the iron core w...
