Definitions

  • This invention relates to the transmission of data, and especially multiplexed serial data transmission.
  • Such systems are increasingly becoming important for a number of applications, for example in military avionics, where data is sent to equipment in the aircraft via a single data transmission bus, or data bus, that is common to a number of items of equipment, and a branched line or stub that connects the equipment to the data bus.
  • a plug-in coupler for forming a splice between a data transmission bus of a multiplexed data trans­mission system and a plurality of stubs, which compri­ses a generally flat housing having a pair of disconnectable connector portions that are connected to each other within the housing by a pair of conductors so that an in-line splice can be formed in the data bus, and an array of contacts for forming releasable connections to a plurality of stubs, the contacts being transformer coupled to the pair of conductors.
  • Each of the stubs is coupled to the data bus within the housing by a transformer coupling arrange­ ment which usually comprises an isolation transformer and a resistance of about 50 ohms on each line between the isolation transformer and the data bus so that a short circuit in one of the stubs, for example caused by damage to the equipment, will not affect the remainder of the data transmission system.
  • a transformer coupling arrange­ ment which usually comprises an isolation transformer and a resistance of about 50 ohms on each line between the isolation transformer and the data bus so that a short circuit in one of the stubs, for example caused by damage to the equipment, will not affect the remainder of the data transmission system.
  • the coupler according to the invention has the advantage that it is particularly compact compared with known systems that use a coupler for individual stubs.
  • the coupler is particularly versatile in that it can easily be removed and changed to accom­modate alteration in the equipment that is controlled by the system, and can be removed for testing or repla­cement.
  • the coupler may be made, for example, in the form of a conventional plug-in rectangular connector having a coupler extension mounted on an end thereof.
  • the connector may then be mated with a corresponding rectangular connector e.g. on opposite sides of a bulk­head in a conventional manner.
  • the fact that the coupler can be made in such a small size has the addi­tional advantage that there is a greater choice of location of the coupler in the aircraft.
  • one problem with conventional databus systems is that, although the main databus can be balanced e.g. by appropriate impedance connections at each end, the con­nection of stub lines to the databus disturbs the balance, and this disturbance is worsened as the stub length is increased.
  • the main databus By using databus couplers according to the invention it is possible for the main databus to extend in a relatively convoluted path so that it passes near (e.g. less than about 6m and pre­ferably less than 3m) to the equipment with a con­sequent reduction in stub length.
  • the main databus it is possible to pass the databus along the aircraft wings and provide a coupler in the region of the missiles or other equipment rather than to provide a long stub from a coupler in the centre of the aircraft fuselage.
  • the disconnectable connector portions and the contacts for forming connections to the stubs are arranged together as a single array in a connecting face of the housing so that the stubs and the data bus may be disconnected in a single operation.
  • This form of coupler is appropriate for use where the data bus is provided for example in the equipment racking system or where a connection can be made to the data bus via the racking system.
  • the contacts for forming connections to the stubs are arranged together as a single array in a connecting face of the housing and the disconnectable connector portions for the data bus are located at separate points on the housing spaced apart from the connecting face of the housing.
  • coupler is appropriate where, for example equipment or racking for the equipment is to be installed and the data bus extends outside the equipment or racking.
  • the connec­tor portions for the data bus are preferably arranged on opposite sides of the housing substantially in line with each other, in order to simplify the path of the data bus.
  • the coupler will normally contain connection con­tacts for at least 4 stubs, preferably at least 6 stubs but normally not more than 12 stubs and especially not more than 8 stubs.
  • a coupler 1 for forming a splice between a data bus of a multiplexed serial data transmission system comprises a generally flat die cast aluminium housing 2 that is formed in three parts, a top and bottom shell half 2 and 3, and a connector part 4 which encloses an array (not shown) of male or female contact elements for forming a push fit electrical con­nection.
  • the coupler contains an array of eight coaxial male or female contacts 5 and 6 each comprising a pair of contact elements arranged coaxially, the two con­tacts 5 being connected together within the housing by conductors 7 so that the contacts 5 can be connected to the main data bus in order to form an in-line splice in the data bus when the coupler is pushed into the socket.
  • the six contacts 6 are each connected to the conductors 7 via isolation transformers 8 and 52 ohm resistors 9 mounted on a printed circuit board 10.
  • the connector part is provided with side lugs 11 containing screw-threaded bolts 12 for firmly fixing the connector part 4 of the coupler to a bulkhead, racking tray or the like that contains a mating connec­tor socket.
  • coupler has a flat housing comprising top and bottom shell halves 2 and 3 and con­nector part 4 which encloses an array (not shown) of male or female contact elements for forming a push-fit electrical connection.
  • the housing has two disconnectable connector por­tions 13 and 14 that are connected to each other within the housing by conductors 7 so that an in-line splice can be formed in a data bus that extends outside the bulkhead, equipment or equipment racking system.
  • the coupler has an array of eight coaxial male or female contacts 6 that are connected to the conductors 7 via isolation transformers 8 and resistors 9 which are mounted on a printed circuit board (not shown) in the same manner as in figure 3.
  • side lugs 11 containing screw-threaded bolts 12 are provided for fixing the connector part 4 to a bulkhead or racking tray.
