If the first contact portion 623 is always in contact with the third contact portion 625, when the second contact portion 624 is in elastic contact with the signal contact 440, the first contact portion 623 slides a certain distance relative to the third contact portion 625.
  • the first contact portion 623 is spaced a predetermined distance relative to the third contact portion 625, when the second contact portion 624 is in contact with the signal contact 440, the first contact portion 623 gradually approaches the third contact portion 625 until it contacts the third contact portion 625, and can slide a certain distance relative to the third contact portion 625 after the contact.
  • the connector 600 also includes a connecting sleeve 626, which is sleeved on the first contact portion 623 and the third contact portion 625 to constrain the first contact portion 623 and the third contact portion 625, so that the first contact portion 623 and the third contact portion 625 can move relative to each other within a predetermined range, thereby avoiding separation of the first contact portion 623 and the third contact portion 625, and effectively ensuring that when the second contact portion 624 contacts the signal contact 440, the first contact portion 623 can stably contact the third contact portion 625.

Abstract

La présente invention concerne un connecteur électrique et un dispositif électronique. Le connecteur électrique comprend un ensemble fiche, l'ensemble fiche comprenant une carte de carte de ligne pourvue d'un trou de filetage, le trou de filetage permettant à au moins un câble de transmission de passer à travers celui-ci, et la carte de carte de ligne étant connectée à au moins un fil et/ou une couche de blindage qui fournissent un blindage de signal dans le câble de transmission. La présente invention réduit au moins la probabilité d'interférence mutuelle se produisant entre des câbles de signal à l'intérieur d'un connecteur électrique, et atténue également la contradiction entre la complexité et la précision du connecteur électrique et des exigences insuffisantes pour un espace interne, de telle sorte que la précision d'installation et la fiabilité de connexion peuvent être améliorées, et l'isolation de blindage de diaphonie entre des lignes différentielles est réalisée, ce qui permet d'améliorer la qualité et la stabilité de transmission de signal.
