Abstract
The utility model discloses a kind of three sub-line data bus couplers, comprising: circuit board module, large overcoat, shell with holes, shell, the little overcoat of four sub-lines, the little overcoat of three sub-lines, three strip lines, two buses, pad; Described shell with holes and shell coordinate, described circuit board module is arranged on enclosure, described pad is located at shell with holes and outer casing inner wall, described large outer being sheathed on outside shell with holes and shell and by coordinating with the little overcoat of four sub-lines and the little overcoat of three sub-lines forms enclosure space, described two strip lines and a bus are located in the little overcoat of four sub-lines, a described strip line and a bus are located in the little overcoat of three sub-lines, and the end of described sub-line and bus is connected with circuit board module respectively.The utility model has effectively been realized interior of aircraft transfer of data, by assessing aircraft system situation the monitoring of data.
Description
Technical field
The utility model relates to the bus coupler structure of transfer of data, and a kind of three sub-line data bus couplers are provided especially.
Background technology
Existing bus coupler structure, ubiquity volume is large, poor sealing performance, ambient temperature requires high defect, be not suitable for the output of interior of aircraft signal data and signal testing, bus coupler is the present situation in abroad being monopolized for a long time, and expensive, therefore, design and a kind ofly can meet that serviceability requires, body is less, lightweight, good airproof performance, can under adverse circumstances, use, be applicable to that interior of aircraft signal data is exported and three sub-line data bus couplers of signal testing have great meaning.
Utility model content
The purpose of this utility model is to provide a kind of three sub-line data bus couplers, can effectively address the above problem.
The technical solution of the utility model is: a kind of three sub-line data bus couplers, comprising: the little overcoat of the little overcoat of circuit board module 1, large overcoat 2, shell with holes 3, shell 4, four sub-line 5, three sub-line 6, three strip lines 7, two buses 8, pad 9; Described shell with holes 3 and shell 4 coordinate, described circuit board module 1 is arranged on shell 4 inside, described pad 9 is located at shell 3 with holes and shell 4 inwalls, described large overcoat 2 is located at shell 3 with holes and shell 4 is outer and form enclosure space by coordinating with the little overcoat 5 of four sub-lines and the little overcoat 6 of three sub-lines, described two strip lines 7 and a bus 8 are located in the little overcoat 5 of four sub-lines, a described strip line 7 and a bus 8 are located in the little overcoat 6 of three sub-lines, and the end of described sub-line 7 and bus 8 is connected with circuit board module 1 respectively.
Preferably, described circuit board module 1 comprises wiring board and is located at three coupling transformers 10 and six resistance 11 on wiring board; The secondary two ends of described each coupling transformer 10 are respectively connected in corresponding bus 8 by a resistance 11, and the elementary two ends of described each coupling transformer 10 are connected with a strip line 7.
The utlity model has following useful effect:
The utility model can be arranged on interior of aircraft, two terminators need to be installed in leader cable two ends, this terminator is the resistor that resistance value equals data bus cable characteristic impedance, the utility model bus coupler working method is half-duplex operation, mainly be divided into stub to leader cable signal testing and leader cable to stub signal testing, by detecting input signal carry out transfer of data consistent with phase of output signal, effectively realized interior of aircraft transfer of data, by assessing aircraft system situation the monitoring of data; The utility model adopts line type structure, is convenient to install exchange and maintenance, and technical performance is excellent, and lightweight, volume is little, and sealing is strong, without height change impact, can be under-55 ℃～75 ℃ conditions steady operation.
