The present invention relates to a medicament injection device (100) that comprises a housing (110, 120) and an actuator (400, 500) configured for expelling medicament from a held reservoir (200) through an injection needle (250). A needle shield (150) is movable from a distal position through an intermediary position and further proximally to activate dose expelling. A carrier (300) movable within the housing (110, 120) holds the injection needle (250). A detent mechanism couples carrier (300) with the needle shield (150) as the needle shield (150) moves from the distal to the intermediary position. When the needle shield is moved further proximally the detent mechanism decouples the carrier (300) from the needle shield (150). A carrier spring device (680) is arranged between the housing (110, 120) and the carrier (300). The injection device (100) provides increased safety against potential damage to the injection needle (150) in case the injection device (100) is dropped on a hard surface.

The invention relates to a high-voltage power line carrier signal communication coupling method and a device. The device comprises two groups of semi-annular transformers, wherein one group is current transformers, and the other group is carrier transformers; each group is divided into an upper half part and a lower half part which are respectively arranged in the upper casing and the lower casing of a high-voltage transmission line; and two semi-annular transformers in the upper casing are respectively wound by coils which are connected with a circuit board arranged at the upper side. When the upper casing provided with the two semi-annular transformers is combined with the lower casing provided with two semi-annular transformers to clamp on the high-voltage power line, the transformers are respectively form complete current transformers and carrier transformers; the high-voltage line penetrates through the center of a magnetic circuit to generate electric current which is used for supplying power for equipment after being converted; and the carrier transformers are used for coupling carrier signals to the high-voltage power line or inducing carrier signals from the high-voltage power line, and the carrier signals are transmitted to ground equipment in a wireless mode. The invention solves the problem of difficult insulation and isolation between the ground equipment and the high-voltage power line, realizes remote meter-reading at low voltage, and saves cost.
