  • Patent number: 10411398
    Abstract: An electrical plug connector terminates a twisted pair electrical cable. The electrical plug connector includes a base and a plug housing holding electrical contacts therebetween. The base includes a divider structure including separation walls. At least one of the separation walls defines an abutment surface against which a forward end of the electrical cable abuts when terminated by the electrical plug connector. The plug housing defines slots so that the electrical contacts are accessible. The electrical plug connector axially secures an outer jacket of the electrical cable against rearward movement relative to base. The at least one separation wall inhibits forward axial movement of the outer jacket of the electrical cable relative to the base.

  • Patent number: 10260662
    Abstract: Described is a fitting for coupling fluidic paths which facilitates secure and low leak rate fluid flow through a fluidic path junction such as a junction in a liquid chromatography system or other chemical analysis instrument. Fluid containing various mixtures of chemical samples can pass through the junction at high pressure with little or no trapped residue remaining in a volume at the connection. According to various embodiments, a face seal is achieved between two separate fluidic path features. In some embodiments, the sealing of the fluidic paths is aided by the use of a compliant polymer seal. The seal facilitates intimate contact between adjacent surfaces and significantly limits or prevents the entry of fluid under high pressure into an unswept volume. Thus the risk of carryover and its adverse effect on measurements is reduced or eliminated.

  • Patent number: 9946035
    Abstract: A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also allow the connector assembly to be accessed easily in high density connectivity environments. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector assembly is constructed using a small number of parts, thereby maintaining low maintenance costs while yielding a sturdy structure. A puller can be added to the connector assembly to improve access in congested connectivity applications without increasing the size profile. Chamfered front faces afford a degree of alignment tolerance when plugging the connector assembly into an adapter. Features of the connector assembly can be implemented in both a duplexed housing version as well as a paired simplex clipped version.

  • Patent number: 9800337
    Abstract: An optical transmitter including an optical connector port, a first light emitter, and a second light emitter. The optical connector port is configured to connect to a connector of an optical cable in a first orientation or a second orientation. The first light emitter is configured to transmit a first optical signal for transmission through the optical cable. The first optical signal transmitted by the first light emitter is reflected by a region of the connector when the connector is attached in the first orientation. The second light emitter is configured to transmit a second optical signal for transmission through the optical cable. The second optical signal transmitted by the second light emitter is reflected by the region when the connector is connected in the second orientation different from the first orientation.
