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.
[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 flexible connected current collector and a preparation method thereof. The current collector is composed of three leads, a flexible circuit board and a rigid connector, and four groups of pads are symmetrically arranged on the front and back of the flexible circuit board. , the four pads on the same side of the flexible circuit board are insulated in pairs, and each group of pads arranged symmetrically on the front and back of the flexible circuit board is mirror-symmetrically conducted through the metallized conductive vias; there are two leads respectively connected to the flexible circuit board. The front pads in the two groups of pads on the circuit board are welded and connected, and the other lead wire is welded and connected with the reverse pads in the third group of pads on the flexible circuit board; the two wings of the flexible circuit board extend from the rigid connector. The fourth group of pads is located on the top of the flexible circuit board, and the top of the flexible circuit board is bent downward to form a V-shaped structure and then welded to the rigid connecting member to achieve conduction with the outside world. The current collector of the present invention has good signal transmission quality and strong anti-vibration capability, so that the missile guidance accuracy is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of precision electronic components, and particularly relates to a flexible connected current collector and a preparation method thereof. Background technique [0002] Frame gyroscopes are widely used in missile weapon systems to measure the flight attitude of the missile body. Since the attitude of the missile body changes during flight, and the attitude of the inner and outer frame systems of the frame gyroscope remains unchanged in the inertial space, there is a relative rotation relationship between the inner and outer frame systems and the missile body. It is a technical problem to realize the reliable transmission of the signal from the inner and outer frames to the data acquisition system on the bomb without spraining the transmission line, and to have a small impact on the performance of the frame gyroscope. [0003] At present, the common method is to use slip rings to achieve reliable transmission ...
