Definitions

  • the present invention relates to an electric wiring construction having a bus bar for supplying electricity to one or more electricity-consuming components.
  • a first connection terminal is connected with the bus bar by means of a first screw tightened into the bus bar.
  • a second connection terminal is connected with the bus bar by means of a second screw tightened into the bus bar.
  • An input line is connected with the first connection terminal, and an output line for supplying electric current to one or more other electricity-consuming components is connected with the second connection terminal.
  • the various electricity-consuming components installed on a vehicle are powered by electricity generated by a generator which is operated by the actuation of the engine.
  • a relay box is provided on an electricity supply path connected with the electricity-consuming components.
  • the relay box accommodates a plurality of relays for switching the supply of electric current to electricity-consuming components, to turn them on and off.
  • Fig. 6 shows a known relay box 11.
  • An electrically conductive bus bar 12 is installed on the relay box 11. Relays are electrically connected with the bus bar 12. A part of the bus bar 12 is exposed on an outer surface of the relay box 11. Electricity generated by a generator is transmitted to the relays through an input line 13 and the bus bar 12.
  • the input line 13 is crimped to connect it with a crimping portion 151 of a first connection terminal 15.
  • the first connection terminal 15 is connected with the bus bar 12 by a first screw 16 tightened the bus bar 12.
  • the bus bar 12 for supplying electricity to the relays is also used to supply electricity to other electricity-consuming components other than via the relays.
  • An output line 14 for supplying electricity to the other electricity-consuming components is crimped to connect it with a crimping portion 171 of a second connection terminal 17.
  • the second connection terminal 17 is connected with the bus bar 12 by a second screw 18 tightened into the bus bar 12.
  • the electricity generated by the generator is transmitted to the relays accommodated inside the relay box 11 and the output line 14 through the input line 13 and the bus bar 12. That is, through the bus bar 12, electricity is sent to the other electricity-consuming components positioned at the other end of the output line 14.
  • electricity passes through the bus bar 12, heat is generated by the bus bar 12.
  • the generated heat is transmitted to the first and second connection terminals 15 and 17 and the first and second screws 16 and 18. Owing to the heat transmission, the first and second connection terminals 15 and 17 and the first and second screws 16 and 18 are heated.
  • the input line 13 is fixed by crimping to the first connection terminal 15, and the output line 14 is fixed by crimping to the second connection terminal 17.
  • a power source terminal assembly comprising a bus bar with first and second connection terminals connected thereto by screws is disclosed in document US-A-4 486 058.
  • the present invention provides an electric wiring construction having a bus bar for supplying electricity to one or more electricity-consuming components; a first connection terminal is connected with the bus bar by means of a first screw tightened into the bus bar; a second connection terminal is connected with the bus bar by means of a second screw tightened into the bus bar; an input line is connected to the first connection terminal; and an output line for supplying electric current to one or more other electricity-consuming components is connected to the second connection terminal.
  • the first connection terminal and the second connection terminal are connected to each other by a bypassing member.
  • the first connection terminal and the second connection terminal each have a respective crimping portion; one end of the bypassing member and the input line are crimped to the crimping portion of the first connection terminal; and the other end of the bypassing member and the output line are crimped to the crimping portion of the second connection terminal.
  • one end of the bypassing member is connected with at least one of the first connection terminal and the bus bar by means of the first screw tightened into the bus bar; and the other end of the bypassing member is connected with at least one of the first connection terminal and the bus bar by means of the second screw tightened into the bus bar. That is both the bypassing member and the connection terminals are connected with the bus bar by tightening the screws into the bus bar.
  • the bus bar is installed on a relay box accommodating a plurality of relays, and the relays are electrically connected with the bus bar.
  • FIG. 1 A first embodiment of the present invention will be described with reference to Figs. 1 and 2. Constituent components of the first embodiment which are the same as those shown in Fig. 6 are denoted by the same reference numerals as those used in Fig. 6.
  • an exposed core wire at an end portion of an input line 13 and an exposed core wire at an end portion of an electrically conductive bypassing line 19 are crimped to a crimping portion 151 of a first connection terminal 15.
  • the terminal 15 is connected with a bus bar 12 by means of a first screw 16 tightened into the bus bar 12.
  • An exposed core wire at an end portion of an output line 14 and an exposed core wire at an end portion of the bypassing line 19 are crimped to a crimping portion 171 of a second connection terminal 17, which is connected with the bus bar 12 by means of a second screw 18 tightened into the bus bar 12.
  • Fig. 2 shows the wire construction of Fig. 1 connected to a generator 20, which generates electricity by the actuation of the engine of a vehicle for transmission to various electricity-consuming components.
  • a relay box 11 accommodates fuses 21, 22, 23, and 24 and relays 25, 26, 27, and 28.
  • the relay 25 performs switching of electric current supply to a glow plug 29, which is an electricity-consuming component, to turn the glow plug 29 on or off.
  • the relays 26 - 28 perform switching of electric current supply to a heater (not shown), which is another electricity-consuming component, to turn the heater on or off.
  • the fuse 24 is electrically connected with an electricity-consuming component which is not shown in Fig. 2.
  • the output line 14 is connected with a bus bar 31 accommodated inside a fuse box 30.
  • the bus bar 31 is electrically connected with a battery 33 through a fuse 32.
  • the bus bar 31 is also electrically connected with an electricity distribution part 35 through a fuse 34.
  • the electricity distribution part 35 distributes electric current to various electricity-consuming components.
  • a plate-shaped bypassing member 36 and first and second connection terminals 15 and 17 are connected with a bus bar 12 by means of first and second screws 16 and 18 tightened into the bus bar 12.
  • the bypassing member 36 is interposed between the connection terminal 15 and the head of the first screw 16 and between the second connection terminal 17 and the head of the second screw 18.
  • the heat transmission area of the plate-shaped bypassing member 36 is greater than that of the bypassing line 19 of the first embodiment. Therefore, the bypassing member 36 prevents the temperature rise of the bus bar 12, the first connection terminal 15, the second connection terminal 17, the first screw 16, and the second screw 18 more effectively than the bypassing line 19 of the first embodiment.
  • a bypassing member 36 is interposed between a bus bar 12 and a first connection terminal 15 and between the bus bar 12 and a second connection terminal 17.
  • an input line 174, an output line 172, and a bypassing line 173 are formed integrally with one another to form a lead wire 175.
  • a core wire of the lead wire 17, exposed by removing the covering of the lead wire 17, is crimped to crimping portions 151 and 171.
  • the fourth embodiment provides effects similar to those of the first embodiment.
  • the present invention may ensure good electrical contact between the connection terminals and the bus bar.
