Patent number: 9203224Abstract: Provided is an electrical junction box which prevents a bonder cap from falling out of a bonder cap accommodating part without using a bundling tie. The electrical junction box includes a frame having a bonder cap accommodating part and a terminal-attached wire accommodating part, and a cover. An edge forming an insertion port of the bonder cap accommodating part includes a low pro file portion with the same height as that of an edge of the terminal-attached wire accommodating part and a projecting portion projecting beyond the low profile portion. In a state where the cover is attached to the frame, a distance between the low profile portion and the cover is longer than the full length of the bonder cap, and a distance between the most projected portion of the projecting portion and the cover is shorter than the full length of the bonder cap. The wire bundle outside the bonder cap accommodating part is bent toward the low profile portion.Type: GrantFiled: August 21, 2013Date of Patent: December 1, 2015Assignee: Yazaki CorporationInventors: Masaki Yamamoto, Kazutoshi Kurachi, Kei Tomita, Taisuke Tomita, Takayoshi Marui

Patent number: 9054508Abstract: An electrical junction box includes a frame, a bus bar and a relay to be mounted to the frame, a junction terminal interconnecting a plate-like terminal portion of the bus bar and a plate-like terminal portion of the relay. The junction terminal includes a tubular portion having a pair of opposing walls and a spring portion arranged in the tubular portion such that the plate-like terminal portion of the bus bar inserted into the tubular portion from one side is sandwiched between the spring portion and one opposing wall and the plate-like terminal portion of the electronic component inserted into the tubular portion from the other side is sandwiched between the spring portion and the other opposing wall. The frame includes a receiving portion allowing the junction terminal to enter only when it is in correct position and an engagement portion holding the junction terminal inserted into the receiving portion.Type: GrantFiled: September 4, 2013Date of Patent: June 9, 2015Assignee: Yazaki CorporationInventors: Masaki Yamamoto, Kazutoshi Kurachi, Kei Tomita

Patent number: 8927860Abstract: An electrical junction box includes: a case main body provided with a wire receiver for receiving an end of an electric wire at a lower surface side; and a lower cover for covering the lower surface. Further, the electric wire is routed in between the lower surface of the case main body and the lower cover, and guided out from a wire outlet composed of a notch and a projecting piece. A biting prevention piece is projected from an edge of the lower cover toward the lower surface. A receiving groove for receiving the biting prevention piece is provided on an inside of a peripheral wall of the case main body. After the tip of the biting prevention piece pushing aside the electric wires to an inside of the case main body is inserted into the receiving groove, the lower cover is attached to the case main body.Type: GrantFiled: July 15, 2013Date of Patent: January 6, 2015Assignee: Yazaki CorporationInventors: Masaki Yamamoto, Kazutoshi Kurachi, Kei Tomita

Patent number: 8794982Abstract: Disclosed is an electric junction box capable of preventing an electric wire from entering into a second housing and contacting with an electric wire crimped part, and of allowing a bus bar smoothly to insert into a frame. The electric wire includes a frame and a bus bar. The bus bar includes a plate part, a plurality of terminals projecting in parallel with each other from one end of the plate, and an electric wire crimped part projecting from the other end of the plate. The frame includes a first housing accommodating the plate part and the plurality of terminals, and a second housing projecting from an end of the first housing and accommodating the electric wire crimped part. A tubular peripheral wall composing the second housing includes a slit passing the bus bar therethrough upon the bus bar being inserted into the frame.Type: GrantFiled: June 27, 2013Date of Patent: August 5, 2014Assignee: Yazaki CorporationInventors: Masaki Yamamoto, Kazutoshi Kurachi, Kei Tomita
