A method is described for the production of a device for transmitting a signal between two end points, at least one of which is movable relative to the other, and between which a wound line which forms a coil and is contained in a substantially circular cassette is arranged. Further extending lines are connected to the line at the two end points. The cassette consists of two parts, namely a stator and a rotor which is turnable around its axis and around the stator. The two parts of the cassette are connected in secure manner to each other by injection molding, in such a way that the rotor is turnable around a common axis within the stator.

Method for the production of a device for the transmission of a signal

A connecting device couples an explosive charge, triggerable by electric current, to a current source. A two core electrical line has the explosive charge at one end, the current source at the other end and the connecting device in between. The connecting device includes a plug (4) with two plug pins (7,8) extending parallel to each other. In the connected state of the connecting device, a counter plug (5) matingly receives the two plug pins. The plug (4) has a cavity (14) between the two plug pins (7,8) in which a short-circuit element (11) made from a resilient metal is provided. The short-circuit element (11) is moveable relative to the plug pins (7,8) between an operative position and an inoperative position. The short-circuit element (11) extends, from its operative position, which is determined by its shape and resilience and corresponds to the disconnected state of the connecting device, into the space provided for the counter plug in the connected state of the connecting device, by a shorter distance in relation to the length of the plug pins (7,8 ), thereby electrically contacting the plug pins (7,8). In its inoperative position, the short-circuit element (11) is recessed in the cavity (14) of the plug (4) out of electrical contact with the plug pins (7,8) and abutting the front of the counter plug situated in the connecting device in its connected state.

Device to connect an explosive charge with an electric current source

A device for transferring current between two end points between which a ribbon cable (10) extends, the ribbon cable serving for an electric connection and being contained in a cassette in coiled form, the cable having at least two electric wires. Plug pins (12) are connected to bared wires of the ribbon cable (10), the pins being arranged in a prefabricated housing (G) of insulating material. The housing (G) consists of a base body (16) and a cover (17) which are locked to each other in the closed position of the housing (G). Projections (19) are arranged on the cover (17), the projections resting firmly against the plug pins (12) in order to fix the position of the plug pins in a closed position of the housing (G). The ribbon cable (10) is passed through a separating joint (T) disposed between the cover (17) and the base body (16), and is clamped therein in the closed position of the housing (G).

Device for transferring current between two end points

A device for transferring a signal has two end points (6, 8) between which a conductor (10) extends in spiral turns and is arranged within a substantially circular cassette (K). The cassette (K) consists of two parts, a rotor (11) which is turnable about its axis and a stationary stator (12) which surrounds the circumference of the rotor and encloses the conductor (10). On the rotor (11) there is an outward protruding extension (15) for receiving a screw (16) which is displaceable in the axial direction of the cassette (K), and serves for a locking of rotor (11) and stator (12). There is also present on the rotor (11) a spring element (17) which is displaceable by means of a screw (16) and which, in mounting position of the cassette (K), is held firmly on the stator (12) and, in the working position of the cassette (K), is separated from the stator (12) by a space.

Device for transferring a signal between two end points which are

A device for transferring a signal between two end points between which a coiled conductor, contained in a substantially circular cassette, is arranged. At least one of the two end points is movable relative to the other. The cassette consists of two parts, a stationary stator (11) and a turnable rotor (12). On the stator (11) there is arranged a holding element which is under spring force and has a free end which is fixed in the assembled position of the cassette in tensioned state on the rotor (12). The holding element is detachable from the rotor (12) by rotation of the latter, so that, in the operating position of the cassette, it protrudes, in released position, through a space of the cassette, separated from the latter.
