Patent number: 7578679Abstract: In an electric connection box 100, a soldering surface clearance 15 is formed at a lower side of a circuit board 10 for the purpose of protecting those portions of terminals 11a (of the relays 11) and terminals 3a (of a connector 3) which are soldered to a circuit formed on the circuit board 10. In this electric connection box 100, the connector 3 is disposed beside an end 10a of the circuit board 10, and the circuit board 10, the soldering surface clearance 15 and the relays 11 are disposed within the range of a height of the connector 3. In this electric connection box 100, a fixing bracket 4 is formed at an intermediate portion of a rear surface of the connector 3 in a direction of the height thereof, and is fixed to the circuit board 10. The rear surface of the connector 3 abuts against the end of the circuit board 10, and an upper surface cover 1 and a lower surface cover 2 abut respectively against upper and lower surfaces of the connector 3.Type: GrantFiled: February 27, 2007Date of Patent: August 25, 2009Assignee: Yazaki CorporationInventors: Kousuke Kinoshita, Tetsuro Saimoto

Patent number: 5755579Abstract: An electric junction box includes a main case having a component connector, an under case having a harness connector, and a longitudinal busbar, which are mounted by making a board surface of the insulated substrate and the longitudinal busbar cross at right angles, and in which the longitudinal busbar is extended to the connector through junction terminals accommodated in the terminal-accommodating cavity. An under case, which is divided into a plurality of sub-cases corresponding to sub-wiring harnesses, is provided with an insulated supporting board for supporting a plurality of junction terminals and a longitudinal busbar. The described arrangement enables each of the separated insulated supporting boards to be fixedly installed in the main case by means of known ways, such as welding, or the like.Type: GrantFiled: December 20, 1995Date of Patent: May 26, 1998Assignee: Yazaki CorporationInventors: Takeshi Yanase, Tetsuro Saimoto

Patent number: 5480320Abstract: An electrical connection element is of an integral construction formed by blanking and bending (i.e., metal sheet working) a single metal base plate. More specifically, the electrical connection element includes a clamping portion formed at one longitudinal end for compressively clamping an end portion of a connection wire, a resilient connecting portion formed at the other end portion by folding the metal base plate twice, an outer wall portion surrounding the resilient connecting portion, and a pair of flexure prevention pieces which are formed on the metal base plate, and are provided respectively at opposite side walls 14a and 14b of the outer wall portion. A distal end of each of the flexure prevention pieces is slanting at an angle corresponding to the angle of inclination of the resilient connecting portion deformed to a predetermined degree.Type: GrantFiled: September 12, 1994Date of Patent: January 2, 1996Assignee: Yazaki CorporationInventor: Tetsuro Saimoto

Patent number: 5082463Abstract: A busbar interconnecting structure consists of a tab formed integral with one busbar and a slot formed in another busbar. The two busbars are firmly connected by pressing the tab into the slot. The slot has the inner surfaces of its shorter sides formed in an arc so that even when the tab is inserted misaligned into the slot, a four-point contact is obtained at all times between the tab and the slot. The slot is also provided at the shorter sides with risers whose inner surfaces are also formed in an arc shape to increase the contact area between the tab and the slot, thus assuring a more stable electrical contact. The tab, when viewed in cross section, may be rounded at the shorter sides to match the curvature of the internal arc surfaces of the slot, thereby providing a still more stable surface contact.Type: GrantFiled: August 15, 1990Date of Patent: January 21, 1992Assignee: Yazaki CorporationInventor: Tetsuro Saimoto

Patent number: 4995818Abstract: A bus bar interlayer connector structure for use in a junction box comprises a bus in one layer having a tab formed with a longitudinal slit and bent at the central part of the slit at right angles to the bus bar body, and another bus bar in another layer having an elongated hole formed therein and adapted to be pierced with the tab for fixedly securing the latter. The above-mentioned slit extends past the bent base portion of the tab to a pattern portion of the bus bar in another layer. Thus, the bus bar interlayer connection can be ensured, and also the size of the junction box using this connector structure, which requires less space for installation, can be reduced correspondingly.Type: GrantFiled: March 16, 1990Date of Patent: February 26, 1991Assignee: Yazaki CorporationInventor: Tetsuro Saimoto
