Publication number: 20240113463Abstract: A cable connector with improved performance and ease of use. The connector has staggered ports to reduce crosstalk and to prevent incorrect insertion of a plug into a receptacle. The plug may be constructed with subassemblies, each of which has a lossy central portion. Conductive members embedded within an insulative housing of the subassemblies may be used to electrically connect ground conductors within the subassemblies. Further, the connector may have a quick connect locking screw that can be engaged by pressing on the screw, but requires rotation of the screw to remove. Additionally, a ferrule may be used in making a mechanical connection between a cable bundle and a plug and making an electrical connection between a braid of the cable bundle and a conductive shell of the plug. The ferrule may be in multiple pieces for easy attachment while precluding deformation of the cable, which disrupts electrical performance.Type: ApplicationFiled: August 14, 2023Publication date: April 4, 2024Applicant: Amphenol CorporationInventors: Donald W. Milbrand, JR., Prescott B. Atkinson, Brian Kirk

Patent number: 9705255Abstract: An improved broadside coupled, open pin field connector. The connector incorporates lossy material to selectively dampen resonance within pairs of conductive members connected to ground when the connector is mounted to a printed circuit board. The material may also decrease crosstalk and mode conversion. The lossy material is selectively positioned to substantially dampen resonances along pairs that may be connected to ground without unacceptably attenuating signals carried by other pairs. The lossy material may be selectively positioned near mating contact portions of the conductive members. Multiple techniques are described for selectively positioning the lossy material, including molding, inserting lossy members into a housing or coating surfaces of the connector housing. By using material of relatively low loss, loss when the conductive members are used to carry signals is relatively low, but an appreciable attenuation of resonances is provided on pairs connected to ground.Type: GrantFiled: November 20, 2015Date of Patent: July 11, 2017Assignee: Amphenol CorporationInventors: Prescott B.

Patent number: 9583853Abstract: An RF connector module and associated printed circuit board providing high isolation and controlled impedance at RF frequencies. The connector module may be manufactured using conventional manufacturing techniques, such as stamping, insert molding, multi-shot molding and interference fit between components, to provide low cost. A connector module constructed with these techniques may implement a co-planar waveguide structure, with conductive shields for isolation and lossy material to enforce co-planar propagation modes. The printed circuit board may similarly be manufactured using conventional manufacturing techniques, including drilling to form vias. As a result, an interconnection system may be manufactured with low cost. These techniques may be applied to provide performance, including in the form of isolation between RF signals, comparable to that provided by more expensive components.Type: GrantFiled: June 28, 2013Date of Patent: February 28, 2017Assignee: Amphenol CorporationInventors: Marc B.

Patent number: 8968026Abstract: A network interface adapted for high speed networks. The interface includes isolation circuits with a transformer containing two primary coils and two secondary coils. A wire making up each primary coil may be twisted with a wire making up a secondary. These two coils may then be co-wound on a common core. The transformer may be connected to a common mode choke. The isolation circuit may be packaged such that the transformer and coil are in a line, with isolation circuits for a plurality of pairs arranged in parallel. The interface circuit may be packaged in a connector housing, which also may be adapted for high speed performance. The housing may receive multiple isolation circuits in parallel. The housing may also include a mating contact portion in which mating contacts for signal conductors of each pair are positioned along the same side of a cavity.Type: GrantFiled: January 3, 2012Date of Patent: March 3, 2015Assignee: Amphenol CorporationInventors: Mark W.

Patent number: 8771016Abstract: An improved open pin field connector is provided for enhanced performance when carrying high speed signals by selective application of one or more techniques for controlling electrical performance parameters. Lossy material may be positioned adjacent to conductive elements of the connector so as to reduce resonance in pairs of conductive elements and/or to provide a desired characteristic impedance for pairs of differential signal conductors. The lossy material may be shaped and positioned to avoid capacitive coupling that might otherwise increase cross talk. In a right angle connector, the lossy material may have a step-wise increase in thickness to provide comparable loss along longer and shorter conductive elements. Conductive elements may be shaped to balance performance characteristics of pairs selected to carry differential signals regardless of orientation along a row or column.Type: GrantFiled: February 24, 2011Date of Patent: July 8, 2014Assignee: Amphenol CorporationInventors: Prescott B.
