Lossless detector and manufacturing method thereof

Abstract

A lossless geophone, relating to the field of geophones, comprising an outer casing, a magnetic steel, an upper yoke, a lower yoke, and an upper spring piece. The outer casing is fixed with a positive terminal and a negative terminal, and the positive terminal is connected through the upper and outer The contact piece is connected with the upper spring piece, the negative terminal is connected with the upper yoke iron through the upper inner contact piece, and the lower yoke iron is connected with the lower spring piece through the lower contact piece; the winding windows of the upper coil frame and the lower coil frame are brushed with insulation The two ends of the coil are welded to the upper coil frame and the lower coil frame respectively. During manufacture, the insulation layer is brushed on the surface of the winding window; the enameled wire is wound in the winding window of the upper coil frame and the lower coil frame; and the two ends of the enameled wire are respectively welded together with the upper coil frame and the lower coil frame. The invention greatly reduces the requirements for assembly skills, and the welding operation during the coil winding is relatively simple and easy to master; the assembly production efficiency of the geophone can be greatly improved.

Description

technical field [0001] The invention relates to the field of geophones, in detail, it is a non-loss geophone with simple structure, convenient processing, high assembly efficiency, simple and convenient maintenance, reusable components and a manufacturing method thereof. Background technique [0002] We know that the structure of the existing geophone is as follows: an outer casing is provided, a magnetic steel is arranged in the middle of the outer casing, an upper yoke and a lower yoke are respectively arranged on the upper and lower ends of the magnetic steel, and an upper yoke is arranged in the middle of the upper end of the upper yoke. Press the convex ring, the upper spring piece is fixed between the upper pressing convex ring and the outer shell, an insulating layer is provided between the upper spring piece and the upper yoke, the upper spring piece is ring-shaped, and the ring-shaped inner side of the upper spring piece is fixed on the upper yoke Between the upper ...

AI Technical Summary

Problems solved by technology

[0003] The path between the positive and negative poles of the existing detector is: positive terminal - upper outer contact piece - upper spring piece - welding one end of the enameled wire - welding the other end of the enameled wire - lower spring piece - lower contact piece—lower yoke—magnetic steel—upper yoke—upper inner contact piece—negative terminal, in which the conduction between the enameled wire and the spring piece is achieved by pressing the spring piece with the snap ring, and then soldering. The spring sheet is related to many indicators of the geophone. During the production process, due to various factors, some unqualified products will be produced. As long as the unqualified products are repaired, the spring sheet usually needs to be replaced. Once the spring sheet is replaced, because it is different from The enameled wire is connected by welding, so these spring pieces and snap rings are scrapped and cannot be reused. When there are many repairs, the entire coil will be scrapped. Not only the assembly operation is troublesome, the efficiency is low, and the production cost is greatly increased.
