  • Patent number: 12272840
    Abstract: A connection that provides an electrical junction between a first portion of an electrically conducting bus bar and a second portion of the bus bar includes a male portion to be secured to the first portion of the bus bar and a female portion to be secured to the second portion of the bus bar. The male portion and the female portion are able to fit into one another respectively by following a first translational movement of the female portion relative to the male portion along a first axis, followed by a second rotational movement of the female portion relative to the male portion about a second axis perpendicular to the first axis.

  • Patent number: 10886088
    Abstract: A pyrotechnic cut-off device to be connected to an electrical circuit to cut-off, includes a pyrotechnic initiator, a first and a second conductive portion each intended to be connected to the electrical circuit, the second portion being connected in parallel with the first portion and including two conductive elements separated by an insulating segment, at least one of the conductive elements provided with a first fuse element connected in series which is configured to trip when the intensity of the current passing therethrough exceeds a first predetermined value, and a first and a second insulating protrusion, each protruding from a lower face of a movable piston and the first and the second protrusions being located respectively in front of the first portion and the insulating segment. The pyrotechnic initiator is configured to switch the cut-off device from a first current passage configuration to a second current cut-off configuration.

  • Publication number: 20200279711
    Abstract: A pyrotechnic switching device comprising a first and a second pyrotechnic initiators, and a body in which are present: an electrically conductive portion, and a mobile switching element having an insulating relief facing the conductive portion. The device also comprises a fuse element connected in series with the conductive portion, the first initiator being connected to the terminals of the fuse element so that tripping the fuse element actuates the first initiator, each initiator being configured to cause the device to switch from a current conducting configuration to a current interrupting configuration, the mobile switching element being set in motion toward the conductive portion in order to break it by the impact of the relief during switching from the first to the second configuration.

  • Publication number: 20190301768
    Abstract: The present invention is directed to an air diffuser and a method of assembling the same. The air diffuser provides an air flow with an angular direction with respect to a vertical plan. The air diffuser may be made of different sections configured, when assembled, to direct and disperse the air all around the room or preferably a large area such a warehouse or the like.
