An electrical wiring structure of connecting between a first component and a second component with at least four lead wires includes the first component provided with first insertion portions in which the lead wires are inserted, and the first insertion portionsare arranged in two lines and j columns, and the second component provided with second insertion portions in which the lead wires are inserted, and the second insertion portions are in two lines and j columns. Ends of a pair of lead wires are inserted into the first insertion portions and other ends of the pair of lead wires are inserted into the second insertion portions after crossing at an intermediate part.

Electrical wiring structure

A component for an electronic apparatus has an insulating member that has a plurality of through holes in parallel in which the lead wires are inserted and a shield cover in which an insulating member insertion hole where the insulating member is inserted is formed that cut offs an electrical noise. The insulating member is formed in an integrated shape where parts of adjoining cylindrical parts in which the through holes are formed overlapping mutually when seen along an axial direction of the through hole. The insulating member insertion hole becomes a single hole formed identical to an outer shape of the insulating member when seen along the axial direction of the through hole.

Component for electronic apparatus

An electric connection structure includes a plurality of strip-like first terminals and a plurality of second terminals welded to ends in a longitudinal direction of the first terminals. The first terminals are arranged in parallel with intervals therebetween. The first terminals are arranged so that at least a part thereof faces each other. The first terminals are arranged to be offset in the longitudinal direction alternately so that the ends of the first terminals in the longitudinal direction project. The second terminals are welded to the ends in the projected sides in the longitudinal direction in the first terminal.

Electric connection structure

An injector having an injector body, in which a housing opening and a communication hale are provided, includes a supporting member fixed to an actuator, which includes a lead-wire supporting portion that supports ends of lead wires and a plate portion formed integrally with the lead-wire supporting portion. A thickness of the plate portion is smaller than that of the lead-wire supporting portion, and multiple trench portions are provided on a surface of the plate portion so that the plate portion can be easily bent. While the supporting member passes through the housing opening, the lead wires straight move. After an end portion of the supporting member contacts the communication hole, external force is applied to the end portion to bend the plate portion, and thereby the lead wires are bent while moving in the communication hole.

Injector

An injector includes a nozzle body, a main body including a supply port on the outer peripheral surface of the main body and a high pressure passage, and a fuel pressure sensor on an outer peripheral surface of the main body to detect fuel pressure. The high pressure passage has a first passage extending from the supply port in a radial direction of the main body, and a second passage extending from a fuel downstream end portion of the first passage toward an injection hole in an insertion direction of the nozzle body. The supply port and the sensor are diametrically opposed to each other. The main body includes a sensor passage, which branches from the high pressure passage to extend from the fuel downstream end portion of the first passage in an imaginary extension of the first passage so that fuel flows into the sensor through the sensor passage.

A fuel injection apparatus includes a body, a nozzle, a pressure control unit, a physical quantity measurement unit, a first terminal, a second terminal, a positioning member, and a resin connector main body portion. The pressure control unit controls opening and closing of the nozzle The physical quantity measurement unit outputs an electric signal in accordance with a physical quantity of high pressure fuel. The first terminal is connected to the pressure control unit. The second terminal connected to the physical quantity measurement unit. The positioning member integrally holds the first terminal and the second terminal and locates the first terminal and the second terminal at predetermined positions. The connector main body portion receives therein the positioning member.

Fuel injection apparatus

A fuel injection device includes a pressure control portion for controlling operation of a nozzle, and a body portion having therein a bent lead wire hole through which two lead wires of the pressure control portion are introduced to exterior. A first guide member having therein a pair of first guide grooves partitioned by a first partition member is inserted into the lead wire hole from one end side, a second guide member having therein a pair of second guide grooves partitioned by a second partition member is inserted into the lead wire hole from the other end side. The first partition member protrudes from one end portion of the first guide member to have a protrusion portion, which is fitted with a recess portion of the second partition portion at one end portion of the second guide member when the first and second guide members contact.

Fuel injection device

An injector has a body that defines a high-pressure passage for passing high-pressure fuel to an injection hole inside, a needle that is accommodated in the body and that opens and closes the injection hole, an electric actuator that causes the needle to perform the opening and closing action, a lead wire that is arranged in a lead wire insertion hole formed in the body and that supplies an electric power to the electric actuator, and a fuel pressure sensor that is fixed to the body and that senses pressure of the high-pressure fuel. An outlet hole, via which the lead wire extends from the lead wire insertion hole to an outside of the body, is located at a position closer to the injection hole than the fuel pressure sensor is.
