The present invention relates to a unit and a device, comprising a first rigid arm (102,202,32), having a first (110,210) and a second end, a connecting unit (106,206,36), having at least two rigid parts, one of which is fitted with a first connection site (112,212), and another with a second connection site (114,214), wherein at least two of said parts are rotatably mounted, in relation to one another, around an axis of rotation through said connection unit, wherein the first end (110, 210) of the first arm (102,202,32) is connected to the first connection site (112,212) of the connection unit (106,206,36), and wherein the first arm (102,202,32) includes an outer conductor and an inner conductor (120), coaxially arranged and electrically insulated in relation to one another, for enabling transfer of radiofrequency signals between the first rigid arm (102,202,32) and the second connection site (114,214) of the rotatable connection unit (106,206,36).

The device has two parts (12,14) that can be plugged together and that can be coupled by a sliding element (16) fed into one connector part, especially transversely to the plugging direction, and a securing element (24) movable between a starting position and an end position in which it fixes the sliding part in its end position. The securing element is locked in its starting position and is only released for movement to its end position with the connector parts coupled.

The device has a flexible conductor fixed on one side to a movable contact (16.2) and fixed on another side to a part (11.1) of an electric circuit (11). The conductor comprises of a flexible tube (21), electrically conductive by surface, having low flexural rigidity to bend without being crushed and high torsional rigidity to take a form and a position reproducible in a closed state. An independent claim is also included for a gas insulated electrical substation.

A device for connecting conductors to electrical units such as circuit breakers and the like, comprising an oscillating member pivoted in a seat at an electrical contact to be connected to an external conductor, the oscillating member accommodating members for connecting the external conductor to the electrical contact and forming at least one active or closed position, inside the seat, and at least one open position, in which it is possible to preset the device for the particular type of connection to be performed.

A plug receptacle electrical connector and a method of manufacturing such a connector. The receptacle connector comprises a moulded insulating cover (1) which receives a moulded insulating base (36) carrying electrical contacts (60) for engaging contacts of a plug connector (100) inserted into a cavity (2) in the cover (1). To enable the connector to be mounted on a circuit board with the contacts (60) connected to circuitry (not shown) on the board, the contacts (60) have lead portions (64) which project beneath the base (36), the bottom of the cover (36) being open to receive the lead portions (64). Rails (48) on the base (36), which engage in grooves (82 and 88) in the cover, being provided on the sides of the base (36) and having thereon latches (50) for engaging shoulders (52A) defined by the grooves (82 and 88). In the manufacture of the connector, the contacts (60) are selectively plated with gold stripes (not shown) for engagement by the contacts of the plug (100).

An apparatus is provided for use in a device having a battery and one or more power consuming circuit boards that are powered by the battery. The battery connector includes one or more electrical conduits and a housing. Each electrical conduit includes a battery contact, a first circuit board contact, and as second circuit board contacts. The battery contact is for contacting the battery and forming an electrical connection therebetween. The first and second circuit board contacts are for contacting the one or more circuit boards and forming electrical connections therebetween. The housing retains the electrical conduits.

The invention relates to a leaky coaxial antenna (10) comprising an inner conductor (1), a dielectric (2) around the inner conductor (1), and a first shield conductor (4) disposed around the dielectric (2), the first shield conductor having openings (41) distributed in longitudinal direction of the inner conductor (1) and being adapted in that electromagnetic energy passes through the openings (41). A second shield conductor (5) is disposed around or underneath the first shield conductor (4), the second shield conductor (5) being adapted to cover or mask at least a number of the openings (41) of the first shield conductor in a shielded section (S1 - S12). The second shield conductor (5) is arranged discontinuously in the longitudinal direction of the antenna (10) defining uncovered or unmasked portions (AS1 - AS12) of the first shield conductor (4) in the longitudinal direction of the antenna which are adapted in that electromagnetic energy passes through the uncovered portions (AS1 - AS12). Thus, the present invention suggests a two-layer shield for improving the properties of a leaky coaxial antenna with respect to e.g. aerospace applications.
