In-vehicle electronic device and vehicle having the electronic device
View Patent ↗An in-vehicle electronic device is provided which can ensure resistance to static electricity for the in-vehicle electronic device covered with a resin case, is more downsized smaller in the number of components, and inexpensive. An in-vehicle electronic device 43 includes: a resin housing (resin case) 5 ; a control board 7 that is covered with the housing, and accommodated within the housing a battery harness 27 that is a power wiring which supplies power to the control board; a signal harness 31 that is an input/output signal wiring that transmits an input/output signal to the control board; and a metal bracket 1 that fixes the resin housing to a vehicle main body. In the device, a distance between a projection 35 of the metal bracket 1 and the battery harness 27 is set to be shorter than a distance between the projection 25 of the metal bracket 1 and the signal harness 31 to form a discharge gap 33.
1. An in-vehicle electronic device comprising: a resin housing; a control board that is covered with the housing, and accommodated within the housing; a power wiring that supplies power to the control board; an input/output signal wiring that transmits an input/output signal to the control board; and a metal bracket which fixes the resin housing to a vehicle main body,
wherein a distance between the metal bracket and the power wiring is set to be shorter than a distance between the metal bracket and the input/output signal wiring to form a discharge gap.
2. The in-vehicle electronic device according to claim 1 , wherein the power wiring is connected to a vehicle GND or a vehicle battery (negative electrode).
3. The in-vehicle electronic device according to claim 1 , wherein the power wiring is connected to a vehicle battery (positive electrode).
4. The in-vehicle electronic device according to claim 1 , wherein the metal bracket has a structure serving as the vehicle main body.
5. The in-vehicle electronic device according to claim 1 , wherein the metal bracket has a structure serving as a bracket of a load device integrated with the in-vehicle electronic device.
6. The in-vehicle electronic device according claim 1 , wherein the power wiring is connected to the vehicle battery.
