The ethylene-&agr;-olefin copolymer of the present invention is characterized in satisfying the following conditions (A) to (E): (A) a density in the range of 0.92 to 0.96 g/cm3; (B) a melt flow rate (MFR) in the range of 0.01 to 200 g/10 min; (C) a molecular weight distribution (Mw/Mn) in the range of 1.5 to 5.0; (D) possessing only one peak in terms of the number of peaks observed in an elution temperature-eluted amount curve as measured by the continuous temperature raising elution fractionation (TREF) method, from the integrated elution curve obtained by the elution temperature-eluted amount curve, the difference T75−T25 in the temperature and density d respectively satisfy a specific relationship, wherein T25 is the temperature where 25% of the total elution is obtained, and T75 is the temperature where 75% of the total elution is obtained; and (E) possessing one or two melting point peaks, and among these the highest melting point Tm1 and the density d satisfy a specific relationship. Accordingly, this ethylene-&agr;-olefin copolymer exhibits a superior thermal resistance, heat sealability, and processability.
摘要:
A lead wire connection terminal fitment capable of permitting a plurality of lead wires to be readily press-fitted in a single lead wire press fit groove. The terminal fitment may be in the form of a relay terminal fitment, which includes a metal plate formed with a lead wire press fit groove by machining in which lead wires are press-fitted. A pair of inner surfaces of the metal plate defining the lead wire press fit groove therebetween are formed thereon with a plurality of projections and recesses engaged with an outer periphery of lead wires. The projections biting into the lead wires are so arranged that a space defined between the projections opposite to each other is reduced in width at a position thereof spaced by a distance in a depth direction of the lead wire press fit groove, resulting in being divided into a first space portion increased in width and a second space portion decreased in width.

A high-voltage variable resistor capable of significantly reducing a circuit board as compared with a prior art. Terminal fitments each are arranged so as to function as a connector for forming electrical connection between a slide element slid on each of variable resistance patterns and a terminal acting as an output section. A contact point between a contact on a contact support of the terminal fitment and a plate-like member of the slide element is positioned apart from a surface of the circuit board. The terminal fitment includes a positioner, which is positioned outside the pattern in a radial direction thereof, so that the positioner intersects the pattern while being spaced therefrom.

A high-voltage electronic component including a terminal connection structure capable of connecting a lead wire to a terminal fitment without soldering. An insulating substrate having a resistance element for a variable resistor formed on a front surface thereof and a high-voltage resistor are received in a hollow insulating casing. The insulating substrate is mounted on a rear surface thereof with a terminal fitment. The terminal fitment is formed with a press-fit channel in which a lead wire is press-fitted. Upon press fitting of the lead wire, the insulating casing is formed with an opening, through which insulating resin is charged in the insulating casing to form an insulating resin layer in which the terminal fitment and lead wire are embedded.
