A high-voltage connector of a novel structure is disclosed which achieves an improvement in electrical conductivity, a reduced amount of heat generation and the like while realizing stable connection to a mating terminal by a simple structure having a small number of components. A high-voltage connectoris provided with a terminal fittingincluding a terminal body portionin the form of a flat plate to be overlapped on a mating terminalin the form of a flat plate in a plate thickness direction, and a resilient contact portionintegrally provided to the terminal body portionand inclined to an overlapping side with the mating terminal

High-voltage connector

A connectoris provided with a connector housingincluding a wire draw-out opening, a terminalaccommodated in the connector housing, a wireconnected to the terminaland pulled out to outside of the connector housingthrough the wire draw-out opening, and a bracketmade of metal for holding the wirepulled out through the wire draw-out opening. The bracketincludes a first holding portionand a second holding portionto be fixed to each other while sandwiching and holding the wirefrom both sides in a direction perpendicular to an axis of the wire, and a fixing portionto the connector housing

Connector with bracket holding wires drawn out from connector housing

It is aimed to provide a shielded connector capable of improving heat dissipation performance while suppressing enlargement. A shielded connectorincludes a housing, a shield shellfor covering the housingfrom outside, a connection terminalto be accommodated into the housingand electrically connected to a mating device, and an inner conductive memberfor electrically connecting the connection terminaland a wire W. High radiation portionshaving at least a higher radiation rate than a core Wof the wire W are provided on at least some of a surfaceof the housing, a surfaceof the shield shell, a surfaceof the connection terminaland a surfaceof the inner conductive member

Shield connector

The present disclosure provides a connector capable of improving dissipation performance while suppressing enlargement. A connectorincludes a connector housingand terminals T to be accommodated into the connector housingand electrically connected to a mating device. The connector housingincludes upper slope portionsinclined with respect to a horizontal direction at positions vertically above the terminals T in a state mounted on the mating device. Breathable upper breathable filmsare provided in upper through holesprovided in the upper slope portions

Connector

A connector that includes a wire; a housing having a wire draw-out surface, the wire being drawn out from the wire draw-out surface; a shield disposed outside the housing; a first water stop sandwiched between and held in contact with the housing and the shield; and a second water stop sandwiched between and held in contact with the wire drawn out from the wire draw-out surface and the shield, the shield including a water stop holder that holds the second water stop between the wire draw-out surface and the water stop holder.

A method for producing a propylene-based polymer, including polymerizing propylene or propylene and an &#x3b1;-olefin except propylene in the presence of a catalyst with a horizontal polymerization reactor equipped with stirring vanes rotating around a horizontal axis therein by a continuous vapor-phase polymerization, which removes heat of polymerization by heat of vaporization of a liquefied propylene, wherein the reactor can set a plurality of area sections different in temperature in a horizontal direction inside the reactor, and satisfies at least one of i) a temperature difference, &#x394;T=T&#x3c9;&#x2212;T&#x3b1;, between an area section including an upstream end of the reactor (T&#x3b1;) and a downstream end (T&#x3c9;) thereof is 0.1 to 20&#xb0; C. and ii) a temperature difference, &#x394;T=Tx&#x2212;Tz, between an area section including a catalyst feed part (Tx) and dew point (Tz) of a mix gas in the reactor is 0 to 5&#xb0; C.

Method for producing propylene-based polymer

A propylene polymerization reaction apparatus and a production method of a propylene-based polymer are capable of producing a continuous multi-stage polymer in low cost, high productivity and stably, and significantly reducing generation amount of an off-specification product accompanying change of polymerization condition, in multi-stage continuous vapor phase polymerization method of a propylene-based polymer using a catalyst for olefin polymerization. A reaction apparatus for producing a propylene-based polymer by a multi-stage continuous vapor phase polymerization method is used. One or more reactor of a horizontal-type reactor having inside a stirring machine which rotates around a horizontal axis, and a continuous stirred tank reactor to be connected to the horizontal-type reactor are provided, and a production method of a propylene-based polymer using the same.
