A sealing process of LED modules includes a waterproof wire put through a wire-through hole of a heat sink to be connected with a positive-negative solder joints on a PCB board, which are subjected to glue sealing treatment. A waterproof sealing process is operated between the waterproof wire and wire-through hole. The PCB board is fixed on the heat sink. One sealing ring is placed into a groove. A ring of liquid silica gel is evenly applied along the other groove. The heat sink installed with the PCB board and the waterproof wire are inversely buckled on the lens set which is fixed with the solid silica gel ring and liquid silica gel. At least two waterproof sealing rings are used to isolate an LED chip from the outside so as to prevent all water vapor or other harmful gases from corroding the chip and the PCB.

Distributed optical tapping architectures include two or more optical tap terminals daisy-chained together. Each optical tap terminal includes an environmentally sealed enclosure; an optical tapping circuit positioned within an interior of the enclosure, the optical tapping circuit including an tap input, a tap pass-through output, and a tap drop output; and hardened interface locations (e.g., de-mateable fiber optic connection locations, cable-pass through glands, etc.) corresponding to the tap input, the tap pass-through output and the tap drop output.

A fluororesin cable can include an electric wire having a central conductor covered with an insulator, an inclusion, a tape made of a resin, and a sheath made of a fluororesin. The inclusion is arranged along the electric wire. The tape is wound around an outer periphery of an aggregate of the electric wire and the inclusion. The sheath entirely covers the aggregate and the tape. Here, a material for the inclusion is harder than a fluororesin material constituting the sheath.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

A connector plug comprises a hook with flexible edges. The hook has a first beveled surface and a second flat surface. A stopper is coupled to the flat surface of the hook by a first barrel portion of the connector plug. The stopper is coupled to a plurality of ridges with flexible edges by a second barrel portion. The plurality of ridges are also coupled to each other by the second barrel portion. A via extends through the connector plug from one end of the connector plug to the other end of the connector plug.

A seal assembly includes a circular resilient grommet-type seal having one or more through axial openings equal in number to the wires which pass through the seal and a rigid wire channel or guide which is received within a complementary pocket aligned with the seal between the seal and a reaction surface. The rigid wire channel or guide is retained in the pocket and carries any force exerted on the seal by pressure within the device to the aligned reaction surface. A method of installation includes the steps of mounting an electrical device within a component, routing the electrical wires leading from the device through an opening, routing the wires through corresponding openings in a grommet-type seal, pressing the seal into the opening, routing the wires through passageways in the rigid wire channel or guide and installing the guide in a complementary pocket which is aligned with the seal at one end and includes a reaction surface at the other end.
