Problems solved by technology

Due to the high density of pinholes, the large number of connecting pins in the cavity, complex signals, and difficult lead-in technology, the rectangular connector has not been able to realize the wiring-free rigid-flex board design. Generally, ordinary wires are used to connect the motherboard and the four-rectangular connecto

Abstract

The invention, which belongs to the technical field of the avionics, relates to a wiring-free assembly applied to the inside of a flight parameter collection device, particularly to a wiring-free rigid-flex board assembly with four rectangular connectors. The existing rectangular connector has high pin hole density and lots of connecting pins are arranged inside the cavity; and a mother board and four rectangular connectors are connected inside a case by common wires, so that the wiring efficiency is low, the wiring period is long, and an error rate is high. The invention aims at providing a wiring-free design product. A combination structure including a first rigid board, a second rigid board, a third rigid board, a fourth rigid board, a first flex board, and a second flex board is employed by the provided assembly; printed circuits for communication of signals at two ends are distributed on the first flex board and the second flex board in a superposition mode. Using the assembly, a wiring-free design of an avionic product cast with four rectangular connectors is realized; the human error probability as well as the product weight is reduced; wearing of the wiring harness and the case is avoided; and the product maintainability is improved.

Description

technical field [0001] The invention belongs to the technical field of avionics and is applied to a wiring-free assembly inside a flight parameter collector, in particular to a rigid-flex board wiring-free assembly with four rectangular connectors. Background technique [0002] At present, the chassis design of domestic avionics products is generally designed according to the installation position on the aircraft. According to the installation method and the requirements of the docking cable, there are circular connectors, rectangular connectors, dedicated bus or optical fiber connectors, and circular connectors. The technology of using rigid-flex boards to avoid wiring is relatively mature, and there are many types of products that have been practically applied. Due to the high density of pinholes, the large number of connecting pins in the cavity, complex signals, and difficult lead-in technology, the rectangular connector has not been able to realize the wiring-free rigid...
