摘要:
La présente invention concerne un connecteur coaxial (1) à verrouillage par encliquetage comportant deux éléments de connecteur complémentaires (2 ; 3) comprenant chacun un corps tubulaire (5 ; 35) formant contact de masse dans lequel pénètre un contact central (6), mâle et respectivement femelle, retenu dans le corps par l'intermédiaire d'un isolant (7), caractérisé par le fait qu'un premier des éléments de connecteur (2) comporte un organe de retenue (25) apte à exercer un effort radial sur le second élément de connecteur (3), lequel est agencé de sorte que cet effort radial génère un effort axial sur le second élément de connecteur tendant à l'appuyer axialement contre une portée d'appui (19) du premier élément de connecteur, et par le fait que l'un des éléments de connecteur comporte un organe formant contact de masse interne (8) inséré dans le corps correspondant et apte à venir au contact avec une paroi intérieure du corps de l'autre élément de connecteur, en y exerçant une pression de contact relativement forte.

The invention relates to a method for fabricating an optical plug connector, according to which the optical waveguide is immersed with the exposed optical fiber into a powdery adhesive and is withdrawn from the same, whereby particles of the powdery adhesive remain adhered to the surface of the fiber. The fiber with the adhered particles is then inserted into the boring of the ferrule of the plug connector and is fixed therein. The ferrule is heated to a temperature greater than or equal to the melting temperature of the adhesive and is maintained at this temperature. A particular suitability for use in the field is achieved by virtue of the fact that: the bonding of the fiber to the ferrule is carried out in a battery-operated hand-held device (130); the plug with the ferrule is inserted into and held on a receptacle (160) that is placed on the hand-held device (130); inside the receptacle (160), the ferrule is surrounded by a battery-operated electric heating element; the optical waveguide with the fiber is then inserted into the plug and is fixed inside the same by actuating means (129, 136, 137, 141, 143, 151) arranged inside the hand-held device (130), and; finally, the adherence is effected by heating the ferrule using the heating element.

Disclosed is a broadband patch antenna (10) comprising a planar metallic patch sheet (12) that is provided with right-angled edges and is disposed at a predetermined first height (H) above and parallel to the planar base area (11a) of an electrically conducting reflector (11), and a device (13, .., 16) for feeding an HF signal into the metallic patch sheet (12). Said feeding device (13, .., 16) encompasses a conductor (14) which is guided in a vertical direction and in an insulated manner through the base area (11a) of the reflector (11) while ending at a feeding point (16) on the metallic patch sheet (12). In order to substantially improve the broadband range while keeping the structure of the antenna simple, the metallic patch sheet (12) has the shape of a cross while the conductor of the feeding device (13,..,16) is configured between the base area (11a) of the reflector (11) and the metallic patch sheet (12) as an inner conductor (14) of a coaxial conductor arrangement.

The coaxial plug-and-socket connector is for high frequencies, particularly in the GHz range, and comprises a socket part (B) and a plug part (S) as well as an elastic electrical contact element (11). The contact element (11) connects the outer conductor of the socket part (B) to the outer conductor of the plug part (S) and is placed between the plug part (S) and the socket part (B). The contact element (11) comprises a number of elastic parts (13) that, while under radial elastic stress, form a contact point (16b) to the outer conductor of the socket part (B) and a contact point to the outer conductor of the plug part (S). Said contact points (16a, 16b) preferably lie in a plane running perpendicular to the longitudinal axis of the plug-and-socket connector and near a face (25) of the plug part (S). The connector is stable up to approximately 65 GHz.

Disclosed is a method for removably connecting two groups of individual, parallel fibers (12, 12') that end on a plane located perpendicular to the fiber axis and are respectively delimited by a face. According to said method, the faces of the fibers (12, 12') of the two groups are moved towards each other in an axial direction until the faces of all fibers (12, 12') that are assigned to each other hit each other. The fibers (12, 12') of the two groups, which are assigned to each other, are aligned relative to each other in pairs before hitting each other while differences in the lengths of the individual fibers (12, 12') are compensated after said fibers (12, 12') hit each other by elastically deforming the fibers (12, 12'). Such a method allows the disadvantages associated with bending the fibers to be eliminated due the fact that the lengths of the fibers (12, 12') are essentially compensated by compressing the fibers (12, 12') in an axial direction.

The invention relates to a connector device (10), for the detachable connection of at least one light wave guide to at least one optoelectronic component (12), which is arranged and electrically contacted as a chip directly to the surface of a support or a circuit board (11) and which has an optical axis perpendicular to the support or circuit board (11). The application thereof is more flexible and the construction simplified, whereby the light wave guide is provided with a standardized, fibre-optic plug connector (20) at the end thereof for connection. Said connector device (10) comprises a base piece (15) fixed to the surface of the support or circuit board (11), enclosing the optoelectronic component (12) and comprising a through drilling for the optical signal for exchange between the optical component (12) and the light wave guide and said connector device (10) also comprises a coupling piece (17) which connects to the base piece (15) facing outwards and which comprises a socket opening (18) for plugging in the standardised fibre optic plug connector (20).

The invention relates to an attenuation or termination element comprising at least one resistance part (3, 3') which is mounted in an outer conductor (2) and has at least one connection to an inner conductor part (7, 8). Said resistance part (3, 3') is produced from at least two separately produced plate-shaped parts (4, 5; 4', 5') which are preferably provided with a central slit (12, 13) enabling them to be fitted together. Said attenuation or termination element (1, 1') can be economically produced and has high heat dissipation.

Gegenstand der Erfindung ist eine Dualbandantenne (10) mit einer ersten linearen periodischen Anordnung von ersten Einzelantennen (14) für ein erstes Frequenzband und einer zweiten linearen periodischen Anordnung von zweiten Einzelantennen (15, 16) für ein zweites Frequenzband, wobei die Periode der ersten linearen periodischen Anordnung im wesentlichen doppelt so gross ist wie die Periode der zweiten linearen periodischen Anordnung, und wobei die zweiten Einzelantennen (15, 16) abwechselnd zwischen den ersten und oberhalb der ersten Einzelantennen (14) angeordnet sind, und wobei die ersten Einzelantennen (14) und zweiten Einzelantennen (15, 16) als Patchstrahler ausgebildet sind. Bei einer solchen Dualbandantenne wird bei gleichzeitig kompakter Anordnung ein verbessertes Abstrahl- und Empfangsverhalten dadurch erreicht, dass die ersten und zweiten Einzelantennen (14, 15, 16) jeweils eine in einer rechteckigen, elektrisch leitenden, nach oben offenen Box (17, 21, 26) angeordnete Printplatte (18, 22, 27) und mehrere Patchbleche (19, 20; 23, 24, 25; 28, 29, 30) umfassen, welche oberhalb der Printplatte (18, 22, 27) und parallel zur Printplatte (18, 22, 27) mit Abstand übereinander angeordnet sind.
