Publication number: 20200264221Abstract: A radio frequency antenna with a two-piece sealing ferrule. The antenna includes a center antenna and an outer tube surrounding the center antenna. A mounting nut surrounds and is slidable relative to the outer tube. An outer ferrule surrounds and is slidable relative to the outer tube. An inner ferrule that is separate from the outer ferrule surrounds and is fixed to the outer tube. A mating nut is secured to the mounting nut. The threading of the mounting nut and the mating nut together results in the wedging between the inner and outer ferrules which results in the exertion of a first compressive force by the inner ferrule against the outer tube for sealing the inner ferrule and the outer tube and the exertion of a second compressive force of the inner ferrule against the mating nut for sealing the inner ferrule and the mating nut.Type: ApplicationFiled: February 14, 2020Publication date: August 20, 2020Applicant: CTS CorporationInventors: Douglas E. Cors, James M. Post, Robert L. Newman

Patent number: 10658902Abstract: An axial brushless DC motor comprising a stator, a rotor including a magnet, a sleeve bushing extending through the stator and including a pair of opposed distal collars, a motor shaft extends through the sleeve bushing, and a pair of opposed bearings are seated in the respective pair of collars and mount the shaft and a rotor for rotation relative to the sleeve bushing and the stator. The bearings are adapted for thrust, radial support/self-alignment, and angular adjustment of the motor shaft. In one embodiment, a stator overmold member includes a central tube that defines the sleeve bushing and includes a stator shorting ring. In one embodiment, a metal pole piece is seated in a cup-shaped magnet with a rim and the magnetic flux travels through the rim of the magnet and through a magnetic flux sensor.Type: GrantFiled: November 30, 2018Date of Patent: May 19, 2020Assignee: CTS CorporationInventors: Yulanda Y H W King, David Kolberg, Douglas E. Cors, Scott Calkins, Eric Andrina, Kevin C. Wolschlager, William S. Stewart

Patent number: 10483825Abstract: A rotary actuator includes a connector housing with a hollow tube, a separate motor housing clipped to one side of the connector housing, and a separate gear and sensor housing clipped to an opposed side of the connector housing. At least a first gear and a first gear carrier are located within the interior of the hollow tube. A motor shaft extends from the motor through the connector housing into the tube and into engagement with the first gear. A sensor is seated on an exterior surface of the hollow tube and a magnet is housed in the interior of the first gear carrier. The sensor is adapted to change changes in the magnetic field generated by the magnet in response to movement of the magnet.Type: GrantFiled: June 22, 2016Date of Patent: November 19, 2019Assignee: CTS CorporationInventors: Derek L. Crites, Douglas E. Cors, David A. Kolberg, Andy Rutten

Patent number: 10476142Abstract: A radio frequency antenna comprising an inner conductor or antenna surrounded by and spaced from an outer sleeve, the space between the inner conductor and the outer sleeve being filled with a granular or powder insulating material. A sealant material covers a first end of the outer sleeve for sealing and retaining the insulating material in the antenna. A method of making the antenna includes the step of bending the inner antenna and the outer sleeve during assembly following the steps of filling the space between the inner conductor and the outer sleeve with the insulating material and sealing the insulating material in the antenna. In one embodiment, the radio frequency antenna is adapted for transmitting and receiving radio frequency signals in a radio frequency vehicle exhaust control and sensor system.Type: GrantFiled: December 14, 2017Date of Patent: November 12, 2019Assignee: CTS CorporationInventors: Robert L. Newman, Douglas E. Cors, James M. Post
