Problems solved by technology

[0013] D. Poor anti-vibration ability; in a strong vibration environment, especially when there is strong longitudinal vibration, the brush wire is easier to disengage from the slip ring, resulting in large burrs in the output signal, which affects the guidance accuracy;
[0014] E. The labor cost is high during use, and the positions of the brush wires and the conductive rings of the slip ring need to be manually adjusted repeatedly, and the bottom slip ring is the most difficult to adjust the brush wire due to the limited space position
[0015] To sum up, in the case of continuous relative rotation, the slip ring is a method to solve the frame gyroscope guidance signal transmission, but in the case of small relative rotation, the slip ring is not necessarily the best signal transmission method , because this method has a greater impact on the quality of the transmitted signal and the drift of the gyroscope

Abstract

The invention discloses a high-reliability flexible connection current collector and a production method thereof. The current collector is composed of three leads, a flexible circuit board and a rigidconnecting piece. Four groups of bonding pads are symmetrically arranged on the front and back surfaces of the flexible circuit board, the four bonding pads on the same surface of the flexible circuit board are insulated pairwise, and each group of bonding pads which are symmetrically arranged on the front surface and the back surface of the flexible circuit board are conducted in a pairwise mirror symmetry manner through metallized conductive via holes; two leads are welded and conducted with the front bonding pads in the two groups of bonding pads on the flexible circuit board, and the other lead is welded and conducted with the back bonding pad in the third group of bonding pads on the flexible circuit board; and the two wings of the flexible circuit board extend out of the rigid connecting piece, the fourth group of bonding pads are located at the top of the flexible circuit board, and the top of the flexible circuit board is bent downwards to form a V-shaped structure and then welded to the rigid connecting piece to be connected with the outside. The current collector is good in signal transmission quality and high in vibration resistance, and the missile guidance precision is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of precision electronic components, and in particular relates to a current collector with high reliability and flexible connection and a preparation method thereof. Background technique [0002] Frame gyroscopes are widely used in missile weapon systems to measure the flight attitude of missiles. Since the attitude of the missile body changes during flight, while the attitude of the inner and outer frame system of the frame gyroscope remains unchanged in the inertial space, there is a relative rotation relationship between the inner and outer frame system and the missile body. It is a technical problem to realize the reliable transmission of the inner and outer frame signals to the data acquisition system on the missile without twisting the transmission line, and has little impact on the performance of the frame gyroscope. [0003] At present, the common method is to use slip rings to realize reliable trans...
