Patent number: 7704106Abstract: The invention describes a spring-force terminal connection (2) for electrical conductors with a busbar section (5) and a bent leaf spring (3), which has a bearing limb (7), which is supported on the busbar section (5), a spring bend section (11), which adjoins the bearing limb (7), and a clamping limb (8), which adjoins the spring bend section (11), for fixedly clamping a conductor to the busbar section (5). Those parts (12a, 12b) of the leaf spring (3) which merge with the bearing limb (7) and the clamping limb (8) run in the spring bend section (11) at least partially parallel to one another and bear against one another.Type: GrantFiled: July 2, 2008Date of Patent: April 27, 2010Assignee: WAGO Verwaltungsgesellschaft mbHInventor: Hans-Josef Koellmann

Patent number: 7686662Abstract: An electrical connector assembly includes a sleeve having an upper wall, a base wall, and opposing side walls. The upper wall, the base wall, and the opposing side walls define an opening and an interior within the sleeve. The upper wall defines first and second resilient spring webs. The base wall includes a resilient bridge web having a first mating structure formed therein. A pin is configured for insertion through the opening of the sleeve and into the interior such that insertion of the pin causes flexing of the bridge web and the first and second spring webs. The pin has a second mating structure for engaging with the first mating structure of the bridge web to secure the pin relative to the sleeve. The connecting portions of the first and second spring webs form a joint which is welded to connect the connecting portions of the first and second spring webs.Type: GrantFiled: August 14, 2008Date of Patent: March 30, 2010Assignee: Lear CorporationInventor: Robert Schneider

Patent number: 7660615Abstract: An improved insertion set is provided for transcutaneous placement of a sensor such as a glucose sensor at a selected site within the body of a patient. The insertion set comprises a mounting base defining an upwardly open channel for receiving and supporting a flexible thin film sensor, in combination with a cap assembled with said mounting base to capture and retain a proximal end of the sensor within said channel. The sensor further includes a distal segment with sensor electrodes thereon which protrudes from the mounting base for transcutaneous placement, wherein the sensor distal segment is slidably carried by a slotted insertion needle fitted through the assembled base and cap. Placement of the insertion set against the patient's skin causes the insertion needle to pierce the skin to carry the sensor electrodes to the desired subcutaneous site, after which the insertion needle can be slidably withdrawn from the insertion set.Type: GrantFiled: November 9, 2007Date of Patent: February 9, 2010Assignee: Medtronic MiniMed, Inc.Inventors: Nannette M. VanAntwerp, Edgardo C. Halili

Patent number: 7651363Abstract: The invention describes a terminal component (1) with an insulating housing (2) and at least one spring-force clamping connection (3), which has a bent clamping spring (4), formed from sheet spring steel, with bearing limbs (8) and clamping limbs (7), which are connected to one another via a spring bow (6), a busbar (5), which is inserted into the clamping limb (7) and bears against the bearing limb (8), and a conductor insertion channel (9), which is formed in the insulating housing (2) and extends from the rear spring bow (6) of the clamping spring (4) along the bearing limb (8) at least as far as the busbar (5). The wall, which is formed from the insulating housing (2), of the conductor insertion channel (9) is partially interrupted. That end of the busbar (5) which bears against the bearing limb (8) runs obliquely with respect to the bearing limb (8) and forms a funnel of the conductor insertion channel (9).Type: GrantFiled: May 1, 2008Date of Patent: January 26, 2010Assignee: WAGO Verwaltungsgesellschaft mbHInventor: Hans-Josef Koellmann

Publication number: 20090298315Abstract: A contact has at least one contact portion adapted to contact a first connecting object and a connection portion to be connected to a second connecting object. The contact is provided with an protruded contact portion positioned between the contact portion provided at a free end of the contact and the connection portion and curved and substantially aligned with the contact portion. A member having a pushing portion for pushing the first connecting object is so arranged that the pushing portion is in a position facing to the protruded contact portion. With the contacts thus constructed, even if a great number of the contacts are arranged, large forces are not required for inserting and fitting a connecting object in a connector using the contacts, thereby achieving a stable electrical connection.Type: ApplicationFiled: May 19, 2009Publication date: December 3, 2009Inventors: Yasunaga Iida, Yuki Nakano
