Abstract: An electric connector includes terminal holder including mating-connection space surrounded by holder base and two arms, insert-receiving portion defined at bottom side of holder base, mating-connection plate extended from the holder base and suspended in the mating-connection space and conducting terminals mounted in the mating-connection plate, and circuit board including plug portion inserted through the insert-receiving portion into the mating-connection space of terminal holder, two openings coupled to the arms of terminal holder, upper and lower metal terminals mounted on opposing top and bottom sides of plug portion, planar portion abutted to the bottom surface of mating-connection plate and a plurality of contacts arranged at the back side of the planar portion for the bonding of conducting terminals. Thus, the electric connector has advantages of low profile and low manufacturing cost and is practical for use in a mobile electronic device having light, thin, short and small characteristics.

Abstract: A nano-pigment inkjet ink composition that has a low odor and is environmentally-friendly includes, based on total weight of the inkjet ink composition, from 1 to 10 percent by weight of N-ethyl pyrrolidone; from 1 to 20 percent by weight of propylene carbonate; from 50 to 80 percent by weight of a glycol ether solvent; a pigment that is a nano-pigment having a nano-particle size; a dispersant; a resin; a plasticizer; a surfactant; and from 0.1 to 3.0 percent by weight of an acidity regulator that is at least one cyclic tertiary amine compound. This inkjet ink composition meets both environmental and print quality requirements. The composition has a high flash point and includes raw materials having low toxicity and low odor. It has good storage stability, inkjet stability, and good print quality. Printhead nozzles are not easily clogged. The printed image has high gloss, scratch resistance, and weather resistance.

Abstract: A low odor environmentally-friendly nano-pigment inkjet ink composition has good storage stability, inkjet stability, and good print quality. The printhead nozzles are not easily clogged by such an inkjet ink composition. The printed image has high gloss, scratch resistance, and weather resistance. The inkjet ink composition using low toxic and low odor raw material has a high flash point, and has high security to human health and environment. The inkjet ink composition can meet both the environmental requirement and the print quality requirement. The inkjet ink composition includes 1-10% of N-ethyl pyrrolidone, 1-20% propylene carbonate, 50-80% glycol ether solvent, pigment, dispersant, resin, plasticizer, surfactant, and cyclic tertiary amine compound as an acidity regulator.
