PROBLEM TO BE SOLVED: To rationally use a dummy connector housing without enlarging an electrical junction box. SOLUTION: A replacement cover 30 can be assembled to a case body 2 by replacing with a lower cover 3 of the electrical junction box 1, and the dummy connector housings 32, 33 in which an external female connector to be inserted and jointed to a connector housing 8 can be inserted and jointed are integrally provided at the same position as the connector housing 8 when a wiring body module 4 is housed, thus replacing with the lower cover 3 even when the wiring body module 4 is not housed.

PROBLEM TO BE SOLVED: To provide an electronic control unit storage box which is installed in an engine room of a car and cools an electric control unit with air introduced from a cabin, and is capable of eliminating the possibility that exhaust gas in the engine room flows into the cabin. SOLUTION: The electronic control unit storage box comprises a box body 16 to store an electronic control unit 14, an inner lid 18 to cover an upper opening of the box body in an airtight manner, and an outer lid 20 to cover the upper opening of the box body from the top of the inner lid. An intake/exhaust pipe 40 to circulate air in the box body 16 with air in a cabin B is mounted below the inner lid 18. The electronic control unit 14 placed in a case 22 is stored in the box body 16, and the case 22 is fitted to the inner id 18 in an airtight manner. Even if the outer lid 20 is removed, airtightness between the inner lid 18 and the box body 16 is maintained, and exhaust gas in an engine room A does not flow into the cabin B.

Abstract:
PURPOSE:To smooth the rotation of an engine at the time of fuel-cut reset by controlling the fuel injection so as to be increased for a prescribed time after the reset of fuel cut as compared with the time light fuel is detected, when heavy fuel is detected, on the basis of the detecting signal of a fuel prop erty detecting means. CONSTITUTION:When a throttle valve 17 is fully open and the rotating speed of an internal combustion engine 11 is higher than the cut rotating speed, a fuel injection control means 16 cuts the fuel injection by means of a fuel injec tion valve 12; and when the rotating speed of the engine becomes less than the reset rotating speed, or when the variation per unit time of rotating speed of the engine drops less than a prescribed value, the fuel injection cut is re leased. In this case, if a fuel property detecting means 18 detects that the fuel 15 is a heavy fuel abundant in high boiling-point constituents, an injection increasing means 19 controls the fuel injection control means 16 so that the fuel injection after fuel-cut reset is increased as compared with the time light fuel is detected. Thus, the rotation of the engine at the time of fuel-cut reset can be smoothed, and engine stall can be previously prevented.

PROBLEM TO BE SOLVED: To provide an electric connection box which can surely prevent a connector from being covered with water while simplifying the structure of an upper cover and can eliminate the risk of deforming or damaging the upper cover when it is opened or closed. SOLUTION: In the electric connection box 1, the position forming the first abutting face 3d, a second abutting face 3e and a third abutting face 3f and their neighborhood on the inner side face at the sidewall portion 3b of an upper cover 3 are formed of a flat surface of a curved surface. A protection wall 6 is formed on the inside at the outer circumferential portion 5b of a connector holder 5 while spaced apart by a predetermined distance, and arranged to surround a plurality of connectors 3 entirely. Assuming the height from a predetermined reference point K of a lower cover 2 to the first abutting face 3d is H1, the height to the second abutting face 3e is H2, the height to the third abutting face 3f is H3, and the height to the tip of the protection wall 6 is H4, following relation is satisfied; H4>H3>H2>H1.

Abstract:
PROBLEM TO BE SOLVED: To provide an electric junction box which is suitable to use at the position having a severe temperature change from high to low temperatures such as the engine room in a vehicle. SOLUTION: The electric junction box includes a wiring board 300, a first protective member 100 and a second protective member 200 which accommodate the wiring board while holding the board in between. A projection part 310 being a part of an electric component is formed on one board surface 301 being the surface of the first protective member side of the wiring board, and support column parts 110, 120 the tip end parts 111, 121 of which abut on or separates from the one board surface or the projection body 321 fixed on the board surface is formed on the inside surface facing the one board surface of the first protective member, corresponding to the deformation of the first protective member. The projection part and the inside surface of the first protective member have a clearance to such a degree that they do not interfere with each other when the support columns abut on the one board surface.
