Patent number: 9183981Abstract: A reactor comprises a reactor core in which two U-shaped core members are connected in a ring shape with a gap section therebetween, a primary insert-molded resin part provided covering at least an outer peripheral surface of a leg part of the core member other than an adhesion surface of the core member, a coil placed around the gap section and the leg part of the core member, and a secondary insert-molded resin part made of a thermoplastic resin and which is insert-molded around the coil to fix the coil on the reactor core and fix the leg parts of the core members in a connected state. A positioning section which determines a relative position of opposing leg parts and a window section which allows a melted thermoplastic resin for forming the secondary insert-molded resin part to flow into the gap section are formed on an end of the primary insert-molded resin part connected in a state where core members are placed connected in a ring shape.Type: GrantFiled: June 27, 2011Date of Patent: November 10, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasuhiro Ueno, Fumio Nomizo

Patent number: 9159483Abstract: A reactor device formed by containing a reactor body comprising a plurality of cores joined with each other within a case in a floating state. The reactor body is placed on a case by using leaf spring bodies and a movement of the reactor body in the horizontal direction is allowed, thereby absorbing a difference in expansion resulting from a difference in the thermal expansion coefficient between the reactor body and the case due to a heat stress. Further, a resin mold is inserted into a concave portion of the case so as to allow the movement in the horizontal direction so that the movement of the reactor body along a slope surface can be achieved, thereby absorbing the difference in expansion.Type: GrantFiled: December 27, 2010Date of Patent: October 13, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takahito Murata

Patent number: 9041502Abstract: An electromagnetic device arrangement includes a transformer assembly having a core, windings, and a housing disposed around at least a portion of the core and windings. An enclosure at least partially encloses the transformer assembly. The transformer assembly is mounted to a first portion of the enclosure such that heat is transferred from the transformer assembly to the first portion of the enclosure. A second portion of the enclosure has an extension extending therefrom such that the extension is placed in thermal contact with the transformer assembly to transfer heat from the transformer assembly to the extension.Type: GrantFiled: April 5, 2012Date of Patent: May 26, 2015Assignee: Lear CorporationInventors: Ajmal Ansari, Nadir Sharaf, Slobodan Pavlovic

Patent number: 9027228Abstract: Methods for the manufacture of an electromagnetic coil assembly are provided. In one embodiment, the method includes joining a first end portion of a braided lead wire to a coiled magnet wire. A dielectric-containing material is applied in a wet-state over the coiled magnet wire and over the first end portion of the braided lead wire. The dielectric-containing material is cured to produce an electrically-insulative body in which the coiled magnet wire and the first end portion of the braided lead wire are at least partially embedded. Prior to application of the dielectric-containing material, the braided lead wire is at least partially impregnated with a masking material deterring wicking of the dielectric-containing material into an intermediate portion of the braided lead wire. In certain cases, the masking material may be removed from the braided lead wire after curing, and the electrically-insulative body may be sealed within a canister.Type: GrantFiled: November 29, 2012Date of Patent: May 12, 2015Assignee: Honeywell International Inc.Inventors: James Piascik, Eric Passman, Robert Franconi
