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. 10 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.
  • signal terminals 5 are projected from a side surface of a substantially rectangular body 6 and mounted on a sub-board 7.
  • the bottom surface of the body 6 is disposed in opposition to the surface of the board 2 functioning as a main board, while wiring patterns formed on the sub-board 7 are electrically connected, by means of electric wires 8, to corresponding wiring patterns formed on the board 2.
  • an electric connector comprising a body having a plurality of horizontally extending signal terminals, the signal terminals being projected, as connection terminals, from a side surface of the body, the body being mounted with the side surface opposed to a sub-board and with a bottom surface thereof opposed to a main board, characterized in that in order to connect wiring patterns formed on the sub-board to corresponding wiring patterns formed on the main board, the body is provided with a plurality of L-shaped-connection pins projected from the side and bottom surfaces of the body.
  • connection pins are projected from the vicinity of the lower end of the side surface of the body.
  • connection pins for connecting the sub-board to the main board are provided in the body so as to project from the side surface and the bottom surface of the body from which also the signal terminals are projected. Accordingly, when the body is mounted on the sub-board, the signal terminals are connected to the connection portions formed on the sub-board respectively, while the connection pins projected from the side surface of the body are connected respectively to the wiring patterns formed on the sub-board.
  • connection pins projected from the bottom surface of the body are connected respectively to the corresponding wiring patterns formed on the main board.
  • connection pins provided in the body can be connected to predetermined wiring patterns, for example, by solder dipping or the like, when the body is mounted on the sub-board and the main board.
  • connection pins When the above-mentioned connection pins are projected from the vicinity of the lower end of the side surface of the body, the length of each connection pin can be minimized. Accordingly, the cost of parts for the connection pins can be reduced, and the space occupied by the connection pins in the body is minimized, so that the electric connector per se can be made small in size.
  • Figs. 1 to 9 show the configuration of an embodiment of an electric connector according to the present invention.
  • an electric connector 10 is a connector satisfying ISO Standards and for connecting an automobile audio system.
  • the electric connector 10 is constituted by a body 12 having a bottom surface to be put on a sub-board 11 (see Fig. 2), a first connector 13 constituted by two 8-pin connectors 13a and 13b arranged in the body 12, a second connector 14 constituted by one 5-pin connector, and a conversion connector 20 (see Figs. 7 and 8) to be attached to the second connector 14.

  • This connection may be performed through a lead portion provided in the electric connector 10, or performed through an electrically conductive pattern formed on the sub-board 11.
  • the first contact pin and the fifth contact pin are connected, for example, to the ACC connection terminals of a circuit formed on the sub-board 11.
  • the above-mentioned contact pins 13c and 14a are formed of an electric conductor.

As shown in Fig. 4, one ends of the connection pins 15 are projected from the side surface (the right side surface in Fig. 4) from which also the contact pins 13c of the body 12 are projected, while the other ends of the connection pins 15 are projected from the bottom surface (the lower surface in Fig. 4) of the body 12. At that time, the projecting positions of the opposite ends of the connection pins 15 are disposed close to the corner to thereby reduce the length of the connection pins 15 as much as possible.
  • Figs. 7 and 8 show the conversion connector 20 for short-circuiting connection pins selectively when the conversion connector 20 is attached to the above-mentioned second connector 14.

  • the above-mentioned body 21 has two projecting strip portions 21a extending horizontally along the opposite side edge portions of the flat side surfaces of the body 21.
  • the contact portions 23 of the conversion connector 20 are designed so that the contact portions 23 to be attached to the first and second ones of the four insertion portions 22 are formed integrally with each other while the connection portions 23 to be attached to the third and fourth insertion portions are formed integrally with each other, as shown in Fig. 8.
  • the conversion connector 20 is attached to the second connector 14 while being inserted selectively into the hollow portion of the second connector 14 so that the first contact portion 23 of the conversion connector 20 engages with the first contact pin 14a of the second connector 14, or the first contact portion 23 engages with the second contact pin 14a of the second connector 14.
  • the above-mentioned projecting strip portions 21a are fitted selectively into a pair of recess portions 14b or 14c provided on one side of the hollow portion of the second connector 14 so that the direction of attachment of the conversion connector 20 is determined, and the position of the conversion connector 20 in the longitudinal direction (in the direction of arrangement of contact pins 14a) is restricted.
  • the electric connector according to the embodiment of the present invention is configured as mentioned above.
  • the side surface of the body 12 is mounted on the front surface of the sub-board 11 as shown in Fig. 2 so that one ends of the respective contact pins 13c and 14a and the connection pins 15 are inserted into through holes (not shown) provided in the sub-board 11 respectively.
  • the one ends of the respective contact pins 13c and 14a and the connection pins 15 are soldered to the opposite-side edge portions of the through holes of the sub-board 11, for example, by solder dipping or the like, so that the pins can be electrically connected to a circuit formed on the back surface of the sub-board 11.
  • the electric connector 10 is thus configured.
  • the bottom of the body 12 is put on the upper surface of the sub-board 11 so that the lower ends of the contact pins 13c and 14a are inserted into though holes (not shown) provided in the sub-board 11 respectively.
