Definitions

  • the invention relates to a coaxial connector element for connection to a printed circuit board, wherein a central connecting pin connected to an inner conductor and at least two peripheral connecting pins connected to a hollow cylindrical outer conductor are each provided with a press-in zone for fastening in one bore of the printed circuit board.
  • the object of the invention is therefore to develop a coaxial connector of the type mentioned in such a way that reliable high-frequency tightness is also achieved in the region of the press-in pins on the printed circuit board.
  • the shield sleeve has a first section with a greater wall thickness to form a larger end-face contact surface on the printed circuit board for the purpose of HF-tight shielding and a second section with a smaller wall thickness for overlapping contact with the outer conductor.
  • This second section can be split at least over part of its axial length into a plurality of resilient tabs for contacting the outer conductor.
  • the end face of the shielding sleeve facing outwards or towards the printed circuit board is expediently provided with coaxial webs or grooves. These bars provide reliable contact with the PCB coating and thus ensure high-frequency tightness.
  • This shield sleeve 10 has a first section 11 with a larger wall thickness and also a larger outside diameter. In this section 11, longitudinal grooves 12 are provided, with which the shield sleeve is guided on the peripheral connecting pins 7 with a press fit, but is displaceable.
  • the shield sleeve has a second section 13 with a smaller wall thickness, which has circumferential webs 14 and 15 for contacting the outer conductor 2. Towards the free end, this section 13 is further divided by slots 16 into a plurality of (in the example four) resilient tabs 17, whereby the contact with the outer conductor 2 is improved.
  • the shielding sleeve On the lower, that is to say the end face 18 facing the circuit board, the shielding sleeve also has concentric annular grooves 19 or ring webs 20, by means of which the contact with the circuit board is improved and the shielding is thus secured.
  • the structure of this end face 18 of the shield sleeve is shown in an enlarged detail in FIG. 4.
  • the connecting pins 5 and 7 are thus pressed into the corresponding bores 8a.
  • the shield sleeve 10 comes into contact with the circuit board surface.
  • the shield sleeve is pushed back in the axial direction, the second section 13 of the shield sleeve being pushed into the cavity 21 between the outer conductor 2 and a tubular insulation 22 as required.
  • the space between the circuit board on the one hand and the outer conductor 2 on the other hand is thus completely shielded against high-frequency radiation.

Abstract

Le connecteur coaxial encastrable possède une fiche centrale à encastrer (5) ainsi qu'au moins deux fiches périphériques à encastrer (7) pour établir une liaison sans soudage du conducteur intérieur (1) et du conducteur extérieur (2) sur une plaquette de circuits imprimés (8). Sur les fiches périphériques à encastrer (7) est disposée une douille de protection supplémentaire (10) coulissant dans le sens axial, dont le bord intérieur recouvre le conducteur extérieur (2). Lorsqu'on enfonce la connexion encastrable dans les orifices de la plaquette de circuits imprimés, on fait coulisser la douille de protection selon les besoins et celle-ci établit, indépendamment de la profondeur de pénétration et des tolérances, un bon contact avec la plaquette de circuits imprimés et le conducteur extérieur (2), ce qui assure un blindage HF fiable de la connexion par fiches.

Claims (6)

  1. Connecteur coaxial destiné à être relié à une plaquette à circuits imprimés (8), une broche centrale de raccordement (5) reliée à un conducteur intérieur (1) et au moins deux broches périphériques de raccordement (7), reliées à un conducteur extérieur cylindrique creux (2), étant pourvues chacune d'une zone enfoncée (5a,7a) pour leur fixation dans un perçage respectif (8a) de la plaquette à circuits imprimés (8), caractérisé par le fait qu'une douille de protection (10) est retenue, de manière à être déplaçable dans la direction axiale, sur les broches périphériques de raccordement (7), dans la zone située entre les zones enfoncées (7a) des broches de raccordement (7) et le conducteur extérieur (2), la section (13) de bord, tournée vers l'intérieur, de la douille de protection étant en chevauchement coaxial avec le conducteur extérieur (2).
  2. Connecteur suivant la revendication 1, caractérisé par le fait que la douille de protection (10) possède, dans sa périphérie, des rainures longitudinales (12) parallèles à l'axe, dans lesquelles les broches périphériques de raccordement (7) sont guidées de manière à être déplaçables, selon un ajustement serré.
  3. Connecteur suivant l'une des revendications 1 ou 2, caractérisé par le fait que la douille de protection (10) possède une première section (11) ayant une épaisseur de paroi grande pour former une surface frontale d'application plus étendue, et une seconde section (13) ayant une épaisseur de paroi plus petite servant à établir le contact en chevauchement avec le conducteur extérieur (2).
  4. Connecteur suivant la revendication 3, caractérisé par le fait que la seconde section (13) de la douille de protection (10) est fendue au moins sur une partie de sa longueur axiale, en plusieurs languettes élastiques (17) servant à établir le contact avec le conducteur extérieur (2).
  5. Connecteur suivant la revendication 3 ou 4, caractérisé par le fait que la seconde section (13) de la douille de protection (10) pénètre dans une cavité annulaire (21) située entre le conducteur extérieur (2) et le conducteur intérieur (1) ou un isolant (22) entourant le conducteur intérieur.
  6. Connecteur suivant l'une des revendications 1 à 5, caractérisé par le fait que la surface frontale (18), qui est dirigée vers l'extérieur ou vers la plaquette à circuits imprimés, de la douille de protection (10) comporte des nervures coaxiales (20) ou des rainures coaxiales (19).
