  • FIG. 8D is an end view of the linear RF connector shown in FIG. 8C as viewed from the plug portion 30 side.
  • the shape of the coaxial plug 1 is changed from the straight type to the L type or vice versa by relatively rotating the connector part 10 and the plug part 30 of the coaxial plug 1 around the central axis.
  • the connector portion 10 and the plug portion 30 are maintained in the straight coaxial plug 1 while maintaining the straight shape as illustrated in FIG. Can be made relatively rotatable around the central axis.

Abstract

L'invention concerne une fiche coaxiale comprenant un élément de connexion de conducteur externe et deux éléments de connexion de conducteur central. L'élément de connexion de connecteur externe comprend deux éléments tubulaires dont les formes sont obtenues en divisant un corps tubulaire qui possède un axe central rectiligne en deux sections le long d'un plan de coupe incliné à un angle prédéterminé par rapport à l'axe central. Des sections de raccordement sont formées sur les extrémités côté plan de coupe des deux éléments tubulaires, lesquelles sont à raccorder ensemble pour relier les deux éléments tubulaires entre eux tout en permettant aux éléments tubulaires respectifs de pivoter l'un par rapport à l'autre et par rapport à l'axe central, les plans de coupe des éléments tubulaires respectifs se faisant face l'un à l'autre. Les deux éléments de connexion de conducteur central sont séparés au niveau du point central où se croisent le plan de coupe de l'élément de connexion de conducteur externe et les axes centraux des deux éléments tubulaires. Des sections de connexion qui relient ensemble les deux éléments de connexion de conducteur central de manière rotative par rapport aux axes centraux des éléments tubulaires respectifs se trouvent également au niveau de la position de division, de sorte que les deux éléments de connexion de conducteur central divisés sont positionnés sur les axes centraux des éléments tubulaires respectifs même lorsque les deux éléments tubulaires sont pivotés l'un par rapport à l'autre et par rapport aux axes centraux.
