20090098749 | Electric connection box - An electric connection box includes an electronic circuit board having an electronic component, and a power circuit board having a power circuit, which are disposed upright in a casing. A vertically-extending component area for mounting a heat generating component is formed on the power circuit board, so as not to face the electronic circuit board. A partition wall for separating the component area from the electronic circuit board is provided in the casing, and thereby a first air passage for allowing air to flow vertically along the component area is formed in the casing. A first inlet port connected to the first air passage is formed on the casing, and a first outlet port connected to the first air passage and positioned above the first inlet port is formed on the casing. | 04-16-2009 |
20100134975 | ELECTRIC CONNECTION BOX - In an electric connection box, a heat insulation wall is vertically extended in a case. This forms, between the heat insulation wall and the inner wall of the case, an ascending flow path where air can ascend and a descending flow path where air can descend. An upper communication opening and a lower communication opening that connect between the ascending flow path and the descending flow path are arranged at the upper end and the lower end, respectively, of the heat insulation wall. A relay is placed in the ascending flow path. Among the regions of the case, a region forming the descending flow path is provided with a heat radiation wall section for releasing heat of air in the descending flow path to the outside of the case. | 06-03-2010 |
20100163302 | ELECTRIC CONNECTION BOX - An electric connection box has a circuit board, a conductive member (a first bus bar, a second bus bar, a first connection fitting, a second connection fitting, or a lead terminal) connected to the circuit board and extending in the direction away from the circuit board, a relay provided at the end of the conductive member which is located on the opposite side of the circuit board, and a case for receiving the circuit board and having an opening provided at a position corresponding to the relay. The relay is exposed at the opening to the outside of the case. | 07-01-2010 |
20110005826 | ELECTRIC CONNECTION BOX - An electric junction box having a casing and a circuit structure accommodated in the casing. The circuit structure includes a plurality of first bus bars arranged at intervals and synthetic resin members disposed between the adjacent first bus bars and firmly attached to the first bus bars. The synthetic resin members have heat conductivity higher than that of air. Since the heat generated from the first bus bars during electrical connecting can be transmitted to the synthetic resin members, the electric junction box can be prevented from being locally heated to a high temperature. | 01-13-2011 |
20140218862 | ELECTRICAL JUNCTION BOX - An electrical junction box includes a casing configured to be mounted in a vehicle, a start relay (a start electrical component) A housed in the casing and to which a current is supplied at least at a start of the vehicle, an operational electrical component (an operational relay, a connector, and a fuse connector) housed in the casing and to which a current is supplied at least during an operation of the vehicle, and a surrounding heat shield wall (a heat shield wall) disposed between the start relay and at least one of the operational relay, the connector, and the fuse connector that are the operational electrical components. The start relay includes a relay case (an electrical component case) and a terminal portion. The terminal portion is housed in the relay case and has a fixed contact and a movable contact. | 08-07-2014 |
20140254068 | ELECTRICAL JUNCTION BOX - An electrical junction box includes a casing and a relay housed in the casing. The relay is located at an outer end in the casing. The relay includes an electrical component case and a terminal. The terminal is attached through the electrical component case and includes a fixed contact and a movable contact located in the electrical component case. | 09-11-2014 |
