Definitions

  • the present invention relates to an electric connector for connecting, for example, an automobile audio system, and particularly relates to an electric connector satisfying ISO Standards for connecting various signal lines in a lump.
  • Such an electric connector is configured as shown in Fig. 9 by way of example.
  • an electric connector 1 is mounted on a board 2 of an automobile audio system, for example, by solder dipping, and used for connecting various signal lines, that is, lines for a power supply, audio signals, ACC, BUP and speakers, to the vehicle body side.
  • a speaker connector 3 connected to speakers on the vehicle body side, and a signal line connector 4 connected to a power supply, etc. also on the vehicle body side are connected to the electric connector 1 mounted on the board 2 in a manner as described above, so that the on-vehicle speaker is connected to the automobile audio system formed on the board 2 while electric power is supplied to the automobile audio system, and audio signals are supplied to not-shown apparatus.
  • Such electric connectors satisfying ISO Standards are adopted broadly by automobile makers in various countries, particularly in Europe. Although the connectors are standardized in common, sometimes wire distributions of the connectors may be different in accordance with automobile makers. For example, in some ISO Standard electric connectors, the wire distributions of No. 4 ACC (accessory) and No. 7 BUP (backup) may be reversed to each other.
  • the circuit converting adapter 5 is designed to have removable connection terminals to be provided in the middle of signal lines 5a and 5b for the above-mentioned ACC and BUP so that the connection of those connection terminals can be changed over in accordance with necessity to make the connection of ACC and BUP proper.
  • an electric connector comprising: a first connector having a plurality of signal terminals and adapted to be mounted on a substrate; a second connector having five contact pins aligned at equal intervals, the second and fourth ones of the contact pins being connected respectively to two of the signal terminals of the first connector through which signals are to be changed over, the first and fifth ones of the contact pins being supplied with signals to be changed over; and a conversion connector having four contact portions aligned at equal distances so that the contact portions are adapted to engage respectively with four successive contact pins on one or the other side of the second connector selectively, the first and second ones of the contact portions being electrically connected with each other, the third and fourth ones of the contact portions being electrically connected with each other.
  • either the second or the fourth one of the contact pins of the second connector is connected also to an unused pattern of the first connector.
  • the conversion connector is provided with a protrusion portion or a recess portion for preventing the conversion connector from being attached erroneously reversely to the second connector; and the second connector is provided with a recess portion or a protrusion portion corresponding to the protrusion portion or recess portion of the conversion connector.
  • the first connector and the second connector are formed integrally.
  • signal lines to be changed over are connected to the first and fifth contact pins of the second connector respectively, while the second and fourth contact pins of the second connector are connected to corresponding signal terminals of the first connector respectively.
  • the conversion connector is attached to the second connector so that the first contact portion of the conversion connector engages with the first contact pin of the second connector, the first and second contact pins of the second connector are short-circuited through the first and second contact portions of the conversion connector, while the third and fourth contact pins of the second connector are short-circuited through the third and fourth contact portions of the conversion connector.
  • a signal line on which a signal is to be changed over is connected to the signal terminal of the first connector connected to the second contact pin of the second connector, through the first contact pin of the second connector.
  • the conversion connector is attached to the second connector so that the first contact portion of the conversion connector engages with the second contact pin of the second connector, the second and third contact pins of the second connector are short-circuited through the first and second contact portions of the conversion connector, while the fourth and fifth contact pins of the second connector are short-circuited through the third and fourth contact portions of the conversion connector.
  • a signal line on which a signal to be changed over is connected to the signal terminal of the first connector connected to the fourth contact pin of the second connector through the fifth contact pin of the second connector.
  • the central contact pin of the second connector may be connected to the unused pattern of the first connector through a pair of connection portions of the conversion connector making no contribution to the above-mentioned signal-line changeover connection. Therefore, if a desired signal is assigned to the unused pattern of the first connector, another signal line can be changed over at the same time when the signal lines to the connection terminals of the first connector are changed over.
  • the conversion connector is provided with a protrusion portion or a recess portion for preventing the conversion connector from being erroneously reversely attached to the second connector while the second connector is provided with a recess portion or a protrusion portion corresponding to the protrusion portion or recess portion of the conversion connector, the protrusion portion or recess portion of the conversion connector does not engage with the recess portion or protrusion portion of the second connector in the case where the conversion connector is reversely attached to the second connector. It is therefore possible to surely prevent the conversion connector from being attached reversely.
  • signal lines can be connected to the first and fifth contact pins of the second connector at the same time by mounting the electric connector on the board. It is therefore possible to perform the working of mounting easily and rapidly.
