  • Patent number: 10418767
    Abstract: An adjustable impedance high speed data connector, and methods for assembling and operating thereof. The adjustable impedance high speed data connector of this invention includes a printed circuit board accommodated within, or printed or stamped onto, a tray, the printed circuit board including sets of terminals respectively extending on opposite ends of the printed circuit board. Mounted onto the printed circuit board and electrically connected thereto is at least one electric module having a fixed or adjustable capacitance or a fixed or adjustable inductance, which may be combined in any desired combination to achieve a desired impedance for the connector. By adjusting the variable capacitance or inductance of the electric module (or the variable combinations of capacitance and/or inductance of a plurality of electric modules), the impedance within the connector is adjustable for allowing the connector to operate at various ranges of bandwidths.

  • Publication number: 20190199034
    Abstract: Method of operating a connector latch used to securely hold together a connector apparatus, wherein the connector apparatus has at least a first housing and a second housing which can be mated together. Initially, after the connector latch is manufactured, the connector latch is in an undeflected position. After manufacture, the connector latch is subjected to a pre-mating deflection process, in order to deflect the connector latch into a preloaded position. After the pre-mating deflection process has been completed, the connector latch is locked in the preloaded position. The preloaded connector latch provides a number of desirable characteristics, including at least an extra loud “click” sound when the connecting latch is operated to mate the first housing with the second housing.

  • Publication number: 20190127979
    Abstract: An RC lattice beam is provided that can greatly dampen the transfer of vibrations in particular. As the concrete included in the RC lattice beam is polymer concrete that contains a polymer, fine-scale vibrations that may otherwise affect exposure apparatuses may be effectively dampened, while the depth of the conventional lattice beam may be kept the same. Thus, a high-damping RC lattice beam is provided that is capable of maximizing the performance of a precision exposure apparatus by reducing the defect rate and improving productivity.

  • Publication number: 20190131723
    Abstract: An Insulation Displacement Contact Compliant connector system (IDCC) which includes a housing, header pins, and a Printed Circuit Board (PCB). Each header pin has at least a single barb to be retained into the housing. Each pin has a blade for contacting a wire. A compliant feature on the pin retains itself into holes in the PCB. The housing has a negative space similarly shaped to the pin. The housing includes a strain relief which provides a lead-in for a wire. When the system is fully assembled, the pins reside in the housing, and exit through the housing and into and through respective holes in the PCB. A wire can be inserted into the housing once the pins reside in the housing. There are several options for the assembly process including a) a pin-to-housing insertion process; b) a housing assembly-to-PCB process or a connector-to-PCB process; and c) a wired housing assembly-to-PCB assembly process or a wire harness-to-PCB assembly process.

  • Publication number: 20190109399
    Abstract: A terminal position assurance device (TPA) generally of a “C-shape” design which fits into a housing for an electrical connector, has two arms including a side portion and a ledge portion, and a back portion. The TPA arms flex such that housing breakage is limited. The inward facing surface of each ledge portion has a narrowly tapered shape. The corresponding housing used has a C-shape opening similarly shaped to the TPA. The TPA has stops that engage the housing such that the TPA device can be inserted into the housing at preset and full-lock positions and will not eject out. At a full-lock position, the TPA fully resides in the housing opening completely. The TPA also has associated pads that reduce associated noise with the housing when it is in service.

  • Patent number: 10249975
    Abstract: A numbering scheme for the cavities of a hermaphroditic connector includes indicia on the rear wall of the connector having one or more horizontal rows (n), each row having the same number of cavities (m). A first indicium on the rear face of the rear wall near the cavity at the upper left in a first orientation of the rear wall has an inverted numeral corresponding to the value of ((m)×(n?1)+1)) adjacent to the upright numeral “1.” A second indicium on the rear face of said rear wall near the cavity at the upper right in the first orientation of the rear wall has an upright numeral corresponding to the value of m adjacent to the inverted numeral corresponding to the total number of cavities, which has value m×n. The other cavities may also have indicia following this. The indicia may also contain non-numerical symbols.

    Abstract: A connector position assurance (CPA) device for assuring the full engagement of a female connector assembly and a male connector assembly in a connector apparatus, and the connector apparatus having the female connector assembly and the male connector assembly engaged together when the CPA device is at a full-lock position. Prior to the CPA device being at a full-lock position, the female connector assembly, with the CPA device at a pre-lock position therein, enters the male connector assembly for engagement thereto. At such time, protruding members of a flexible member of the female connector assembly enter a side elongated slot of the male connector assembly.
