Definitions

  • the connector comprises a socket of insulating material, one side of which has apertures for accommodating the contact lugs and another side of which, preferably the opposite side, has apertures for accommodating the ends of the supply wires.
  • the socket is provided with a plurality of resilient elements comprising one or more parts, which at one of their ends can establish a nondetachable contact with one of the contact lugs and at their other end can establish contact with one or more ends of the supply wires.
  • the resilient elements are preferably S-like resilient strips whose ends form an acute angle with an inserted lug, so that the resilient strips exert an axial force on an inserted lug, which prevents the lug from sliding out.
  • the invention relates to a ballast having connector for establishing contact between a plurality of external contact lugs of the ballast and electric device and the stripped ends of supply wires.
  • the connector may be used with a ballast for gas-discharge lamps provided with the standard external lugs.
  • a ballast having connector of the kind described above is characterized in that the connector includes a socket of insulating material, one side of which has apertures for accommodating the contact lugs, and another side, preferably the opposite side, has apertures for accommodating the ends of the supply wires.
  • A-plurality of resilient elements are provided in the socket, one of the ends of the elements can establish a nondetachable contact with one of the contact lugs and the other end can establish contact with one or more ends of the supply wires.
  • a connector according to the invention may be permanently connected to the lugs of an electric device and is suitable for devices formed with standard contact lugs.
  • the contact lugs are located entirely within the insulating socket when using the connector and is therefore safe to the bare hand.
  • the connection of the supply wires is established by introducing the stripped ends of the wires into the socket which wire ends likewise are located entirely within the socket.
  • the connection may be interrupted by detaching the ends of the wires.
  • the apertures for the lugs lie preferably on one line in a side face of the socket and the apertures for the ends of the wires in the opposite side face being located on a line parallel to the first mentioned line, but wherein these lines are located at a different height in the socket.
  • the resilient elements which establish the connection between the ends of the wires and the contact lugs may comprise one or more parts. It is possible to compose the resilient I serted lug. When inserting a lug the said end of the resilient strip will be displaced over a small distance in the direction of movement of the lug, whereafter it forms an acute angle with the lug. The force exerted by the resilient strip on the lug then includes a component which is directed at right angles to the lug and a component which is directed along the axis of the lug, the latter component preventing the lug from sliding out.
  • the contact between the ends of the wires and the ends of the resilient strips cooperating therewith can advantageously be established in the same manner as is described above for the lugs.
  • the contact is then established by simply sliding the stripped end of the wire into an aperture of the connector.
  • means are provided to detach the ends of the wires.
  • This means preferably include apertures in a side face of the socket for introducing tools, for example, a screwdriver by which the resilient force on the ends of the wires can be eliminated.
  • the said apertures may be located in the vicinity of the apertures for the ends of the wires, but they may alternatively coincide therewith.
  • the socket of insulating material preferably comprises two portions, namely a housing the base of which is provided with the apertures for the lugs and a cover provided with the apertures for the ends of the wires.
  • a connector according to the invention may advantageously be used in combination with current-stabilizing ballasts for gas-discharge lamps.
  • the dimension of the connector in the direction of the contact lugs is smaller than twice the length of a contact lug.
  • a ballast according to the invention preferably includes a connector the design of which is such that the connector can be connected to the contact lugs in one manner only. As a result the possibility of erroneous connection of the supply wires is eliminated.
  • FIG. I is an elevational view of an embodiment of a connector according to the invention.
  • FIG. 2 is a cross section taken on the line II-ll of the connector of FIG. 1,
  • FIGS. 3a and b are elevational views of the resilient elements of the connector of FIG. 1, and
  • FIG. 4 shows an embodiment of a part of a ballast according to the invention.
  • the cover of a connector used on a ballast is denoted by the reference numeral 1 in FIG. 1.
  • the cover 1 is molded from insulating material, for example, a synthetic plastic material.
  • the reference numerals 2, 3 and 4 denote apertures in the cover for accommodating ends of connection wires.
  • Two apertures 5 and 6 for accommodating the contact lugs of an electric device are provided in the side of the housing of the connector facing the cover.
  • the apertures 5 and 6 are shown by broken lines in the drawing and are located on a line parallel to the line through the apertures 2, 3 and 4.
  • the cover is again denoted by the reference numeral 1 in FIG. 2 in a cross section of FIG. 1 taken on the line IIII.
  • the housing 7 of the connector is like the cover moulded from insulating material.
  • the resilient element 8 is an S-like resilient strip in this embodiment which is centrally clamped between the cover I and a raised edge 9 of the housing 7.
  • FIG. 3a shows the resilient element 10 formed as a resilient strip and FIG. 3b shows the resilient element 8 likewise formed as the resilient strip of the connector of FIG. 1.
  • One end 11 of the resilient strip 8 may be used to establish contact with a contact lug of a device, and the other end 12 may establish contact with one end of a supply wire.
  • the resilient strip 10 has an end 13 for contact with a lug, and an end 14 which may establish contact with the ends of two supply wires.
  • the reference numeral denotes a ballast for a low-pressure gas discharge lamp according to the invention, which is provided with two standard contact lugs one of which is visible in the Figure and is denoted by the reference numeral 16.
  • a connector according to FIG. 1 is slid onto the lugs. The connector is shown in a cross section.
  • the end [1 of the resilient strip 8 forms an acute angle with the lug 16 so that the connector cannot be removed from the lugs of the device.
  • the end 12 of the resilient strip 8 also forms an acute angle with an inserted wire end 17.
  • the wire end 17 may be detached by introducing, for example, a screwdriver into the aperture 2 of the cover 1 and using it to depress end 12 so as to remove the resilient force on'the wire end 17.
  • the design of the housing 7 and the cover 1 of the connector is such that connection to the lugs of the device 15 is possible in one manner only.
