Abstract: An electrical connector assembly having a printed housing having a first end and a second end. One or more elastomer receiving recesses are provide in the first end, the second end, or both the first end and the second end. Elastomer material is provided in the one or more elastomer receiving recesses. The elastomer is interlocked with the one or more elastomer receiving recesses and the printed housing creating interlocking joints. The interlocking joints between the elastomer material and the housing permanently attach the elastomeric material to the housing.

Abstract: A swept angle RF connector having a 3D printed conductive shell formed in one piece. A dielectric insert positioned in a dielectric receiving passage, the dielectric insert is in the shape of a swept angle and has a circular cross section. A center contact is positioned in a contact receiving passage, the center contact is in the shape of a swept angle and has a circular cross section. The connector has a voltage standing wave ratio below 1.2 for signal frequencies up to 65GHz.

Abstract: An RF module housing with a contact receiving portion and a mounting portion. The contact receiving portion has a mating face and an oppositely facing wire receiving face. The mounting portion has two or more mounting legs. The mounting legs extend from the wire receiving face in a direction away from the mating face. The mounting legs have mounting openings which are spaced an equal first distance from the mating face of the contact receiving portion. The module housing has a mass of no more than approximately 2.0 grams for every 12 RF connections, a Von Mises stress of no more than approximately 250 MPa, and a deformation no more than approximately 0.1 mm.

Abstract: A housing of a connector includes a first section and a second section connected to the first section and extending from the first section. The first section has a first dielectric constant. The second section has a second dielectric constant that is less than the first dielectric constant.

Abstract: A single piece electrical connector having a housing with a mating face, a wire receiving face, and housing side walls. Terminal receiving cavities extend from the mating face to the wire receiving face. The terminal receiving cavities have cavity side walls. Resilient securing arms are provided in the terminal receiving cavities. The resilient securing arms have fixed portions which extend from and are integrally attached to base members which extend from and are integrally attached to the cavity side walls of the terminal receiving cavities. The resilient securing arms are made from the same material and in the same manufacturing process that forms the housing. The fixed ends are spaced from the cavity side walls by gaps. The gaps between the resilient securing arms and the cavity side walls facilitate the cleaning or removal of excess material formed during the manufacturing process of the electrical connector.

Abstract: An electrical connector includes a shell and a coupling ring. The shell has contact receiving passages and an outer wall with a coupling ring retaining projection. The coupling ring is integrally mounted on the shell. The coupling ring is movable between a first position and a second position. A spring is integrally positioned on the coupling ring. The spring is provided in a stressed position when the coupling ring is moved to the second position. Openings are provided in the coupling ring; the openings being positioned proximate the spring. The opening are dimensioned to allow the removal of residual material produced during the manufacture of the electrical connector.

Abstract: A composition for use with a direct light processing apparatus and a method of manufacture. The composition includes a photopolymerizable resin of less than 200 mPa·s measured at 25 degrees Celsius. The photopolymerizable resin cures when exposed to a light of a 405 nanometer wavelength or less. The composition also include a photoinitiator and a metallic powder. The metallic powder has a volumetric concentration greater than 50% of the total volume of the composition. The composition has a viscosity of less than 4000 mPa·s.

Abstract: An electrical connector matable to and unmatable from a separable mating electrical connector includes a housing having a terminal channel and a secondary channel. The electrical connector also includes a female terminal received in the terminal channel. The female terminal is matable with and unmatable from a mating male terminal of the mating electrical connector. An arc suppression element is received in the secondary channel. The arc suppression element configured to electrically couple between the female terminal and the male terminal immediately after the female terminal is disengaged from the male terminal, the arc suppression element providing a bypass between the female terminal and the male terminal so that arcing does not occur when the female terminal is disconnected from the male terminal of the mating electrical connector.

Abstract: An additive manufacturing apparatus and method having a flexible delivery system for delivering pellets from a stationary material receiving area to a movable discharge pump. The flexible delivery system includes a flexible tube, an air compressor and an air-material separator. The air compressor is connected to an end of the flexible tube to direct controlled compressed air through the flexible tube. The air-material separator has a material receiving chamber which receives the pellets from the flexible tube through a material receiving opening. The material receiving chamber extends to a nozzle feeding opening and a nozzle feeding tube. The material receiving chamber has an exhaust opening through which the compressed air is vented out of the air-material separator.

Abstract: A heating device and method for providing temperature control in an additive manufacturing processes. The heating device is positioned circumferentially about a print head and proximate a top layer of a printed object. An area of the top layer of the printed object is heated by directing energy from the heating device to the top layer as material is deposited from the print head onto the printed object. The directed energy applied to the printed object reduces distortion of the printed object caused by temperature gradients and improves the layer-to-layer bonding of the printed object.
