Definitions

  • the present invention relates to a electrical connector according to the introductory part of claim 1.
  • Such an electrical connector is known by the GB-A-2 020 919.
  • Fig. 15 shows a conventional connector of this type, which is made by stripping a length of outer sheath of a shielded cable a and separating the shield wires b from the signal line c , bundling and connecting the shield wires b to the connection terminal d of a connector body d while connecting the signal line c to the connection terminal f by insulation displacement, for example, inserting the connection terminals e and f into the through holes of a printed circuit board g , and soldering them for mounting the connector.
  • Fig. 16 shows another conventional connection method which includes stripping a length of outer sheath of a shielded cable a , separating the shield wires b from the signal line c , bundling and connecting the shield wires b directly to the connection terminal e while connecting the signal line c directly to the connection terminal f by crimping, inserting the connection terminals e and f into the through holes of a printed circuit board g , and soldering them for mounting the terminals.
  • an object of the invention to provide an Electrical connector of the above mentioned kind which permits simultaneous connection of the signal line, shield wires, and outer sheath of a shielded cable, making possible continuous and automatic connection of a great number of signal lines and has an excellent shielding effect.
  • the stripped front portion of a shielded cable is placeble on the board-in connector so that the signal line, the shield wires, and the outer sheath are placed on the signal line connection portion, the shield wires crimping portion, and the outer sheath crimping portion. Then, a connection jig is inserted into the jig inlet to press the signal line and crimping tabs to the signal line connection portion and the shield wires and the outer sheath for effecting simultaneous connection of the shielded cable to the board-in connector.
  • Figs. 1-7 show a shielded cable board-in connector according to an embodiment of the invention.
  • the connector 1 includes a shielding case 3; an insulation body 4; and a signal barrel 5.
  • the shielding case 3 is divided into three portions; a tubular barrel retention portion 6, a shield wires (outer conductor) crimping portion 7, and an outer sheath crimping portion 8.
  • a pair of jig inlets 10a and 10b are formed behind the barrel retention portion 6, with the jig inlet 10a extending rearwardly from the rear edge of a top face of the barrel retention portion 6.
  • the shield wire crimping portion 7 has a pair of U-shaped crimping tabs 12 while the outer sheath crimping portion 8 has a pair of U-shaped crimping tabs 13 which are larger than the crimping tabs 12.
  • a shield terminal 19 extends forwardly from the front end of the shielding case 3.
  • the signal line barrel 5 has a signal terminal 14, a signal line crimping portion 15, and an insulator crimping portion 16.
  • the signal terminal 14 is shaped in the form of a pin and extends forwardly from the front end of the shielding case 3 in parallel with the shield terminal 19.
  • the signal line crimping portion 15 has a pair of U-shaped tabs 17 while the insulator crimping portion 16 has a pair of U-shaped tabs 18.
  • the signal line barrel 5 is supported by the insulation body 4 within the barrel retention portion 6 such that the signal line crimping portion 15 and the insulator crimping portion 16 are positioned in the jig inlets 10a and 10b.
  • a length of outer sheath 23 is removed from the shielded cable 2 to expose the signal line (central conductor) 20, the intermediate insulator 21, the shield wires (outer conductor) 22 as shown in Fig. 1.
  • the shielded cable 2 is placed on the connector 1 such that the signal line 20, the intermediate insulator 21, the shield wires 22, and the outer sheath 23 are placed on the signal line crimping portion 15, the insulator crimping tabs 18, the shield wires crimping tabs 12, and the outer sheath crimping tabs 13, respectively.
  • barrel crimping anvils 24a and 24b and clamper 25a and 25b, and shielding case crimping anvils 26a and 26b and clampers 27a and 27b are operated to simultaneously press the signal line crimping tabs 17 and the other crimping tabs 18, 12, and 13 onto the signal line 20, the intermediate insulator 21, the shield wires 22, and the outer sheath 23, respectively. More specifically, the barrel anvil 24a is inserted into the jig inlet 10a while the clamper 25a is inserted into the jig inlet 10b to press the crimping portion 15 onto the signal line 20.
  • the crimping anvil 24b is inserted into the jig inlet 10a while the clamper 25b is inserted into the jig inlet 10b to press the crimping tabs 18 onto the intermediate insulator 21.
  • the shielding case anvils 26a and 26b and clampers 27a and 27b are operated to press the crimping tabs 12 and 13 onto the shield wires 22 and the outer sheath 23, respectively, to connect the shielded cable 2 to the connector 1.
  • FIG. 9 shows, the shield terminal 19 and the signal terminal 14 are inserted into the through holes of a printed circuit board 28 and soldered at 31 for mounting them on the printed circuit board 28.
  • a great number of shielded cables 2 are connected to connectors 1 as follows:
  • a great number of shielding cases 3 are stamped from a metal sheet, with a strip 30 of the metal sheet left so that the connectors 1 are wound around a reel (not shown).
  • the connector strip 30 is unwound to effect connection of shielded cables 2 to the connectors 1 as described above.
  • Figs 10-14 show a board-in connector according to another embodiment of the invention.
  • the signal line crimping portion 15 is replaced by a signal line insulation displacing portion 33 with a slit 34 extending downwardly from the top edge thereof.
  • the insulation body 4 extends rearwardly up to the end of the signal barrel 5, while the shielding case 3 has only one jig inlet 10a on the top face thereof.
  • the barrel anvil 24a is inserted into the jig inlet 10a to press the signal line 20 covered with the intermediate insulator 21 (or insulated conductor 20) onto the insulation displacing portion 33 for effecting connection by insulation displacement.
  • the other features are the same as those of the above embodiment.
  • the connector according to the invention it is possible to simultaneously connect a shielded cable to the connector by placing the stripped cable on the connector such that the signal line, the shield wires, and the outer sheath are placed on the signal line connection portion, the shield wires crimping portion, and the outer sheath retention portion and inserting the barrel anvil into the jig inlet to connect the signal line to the signal line connection portion while using the crimping jig to press the crimping tabs to the shield wires and the outer sheath.
  • This makes it possible to connect a great number of connectors continuously and automatically.
  • the signal and shield terminals are integrated so that an excellent shielding effect is obtained.
