Abstract
(EN)
A core member, with a cooling liquid passage, for a charging gun, and a plug and a charging gun. The core member comprises a core member body (1) internally provided with a cavity, wherein a tail end of the core member body (1) is a liquid-cooled cable connecting end (11) in communication with the cavity of the core member body; a lateral portion of the core member body (1) is provided with a connector (2), and the connector (2) is in communication with the cavity of the core member body (1); the cavity of the core member body (1) is internally provided with a detachable flow guide member (4); the flow guide member (4) is internally provided with a cooling liquid passage (41); one end of the cooling liquid passage (41) is in communication with the connector (2), and the other end thereof leads to the interior of a head end of the core member body (1); and there is a gap between an outer wall of the flow guide member (4) and an inner wall of the core member body (1). The core member can solve the problem of heat generation and gathering at a contact position between the core member body (1) of the charging gun and a socket, and can take away heat emitted from the contact position, such that the present invention bears a larger current, is simple to manufacture, requires no special technology and tooling, saves on costs, and is suitable for mass production.

L'invention concerne un élément central, avec un passage de liquide de refroidissement, pour un pistolet de charge. L'élément central comprend un corps d'élément central situé à l'intérieur d'une cavité, une extrémité arrière du corps d'élément central étant une extrémité de raccordement de câble refroidie par liquide en communication avec la cavité du corps d'élément central; une partie latérale du corps d'élément central est pourvue d'un raccord, et le raccord est en communication avec la cavité du corps d'élément central; la cavité du corps d'élément central est située à l'intérieur d'un élément de guidage d'écoulement séparable; l'élément de guidage d'écoulement est situé à l'intérieur d'un passage de liquide de refroidissement; une extrémité du passage de liquide de refroidissement est en communication avec le raccord, et l'autre extrémité de celui-ci mène à l'intérieur d'une extrémité de tête du corps d'élément central; en outre, un espace est situé entre une paroi externe de l'élément de guidage d'écoulement et une paroi interne du corps d'élément central. L'invention concerne en outre une fiche et un pistolet de charge utilisant cet élément central. La présente invention peut résoudre le problème de génération et d'accumulation de chaleur au niveau d'une position de contact entre le corps d'élément central du pistolet de charge et une prise, et peut évacuer la chaleur émise à partir de la position de contact, de telle sorte que la présente invention prend en charge un courant plus important, est simple à fabriquer, ne requiert pas de technologie et d'outillage spéciaux, réduit les coûts, et est appropriée pour une production en masse.
