Patent number: 10998656Abstract: An electrical assembly for a motor vehicle transmission includes a printed circuit board (PCB), at least two contact surfaces, at least two contact elements, and a potting compound. The PCB has a component side and the two contact surfaces are arranged on the component side. The contact elements are each electrically connected by a PCB-side first end portion to one of the contact surfaces. The potting compound is arranged on the component side of the PCB, and the contact elements are partly embedded therein. The potting compound directly contacts the contact surfaces and the PCB-side end portions of the contact elements and covers the same. The contact elements protrude from the potting compound by second end portions facing away from the PCB. The electrical assembly includes a chip protection frame that protrudes outward from the potting compound and forms contact chambers for the second end portions of the contact elements.Type: GrantFiled: June 14, 2018Date of Patent: May 4, 2021Assignee: Robert Bosch GmbHInventors: Bernd-Guenter Sippel, Peter Zweigle, Helmut Deringer, Franco Zeleny, Uwe Katzenwadel, Jens Hoffmann

Patent number: 5493217Abstract: The inductive sensor has an electrical coil (14) having winding end portions (114) and current conductors (15) having conductor end portions (115) which are electrically contacted by the winding end portions (114) of the coil in a contact region (18) in the sensor housing (10). A permanently elastic material (26), advantageously silicone, encloses the contact region (18) between the conductor end portions (115) and the winding end portions (114). A temperature-resistant circumferential element (28) bearing on the housing (10) also encloses the contact region (18). This circumferential element (28) can be a polyimide strip or heat-resistant adhesive tape. This inductive sensor allows temperature fluctuation cycles to be increased by up to four times without damaging the coil wire and improves sensor durability.Type: GrantFiled: July 8, 1994Date of Patent: February 20, 1996Assignee: Robert Bosch GmbHInventors: Ulrich Stahl, Uwe Katzenwadel
