Definitions

  • Gas discharge lamps are particularly important for the ignition process be supplied with high voltage, so ensure that to bear that when not used in the recording Exposed contacts are voltage-free to the lamp Ensure operator protection.
  • For non-genre Vehicle headlights are intended for this purpose to arrange the lamp holder on a first plug part, which for the electrical connection with a second Plug part is connectable. Access to the lamp holder and hence to the gas discharge lamp it requires, initially to solve the connection of the two connector parts, with what the lamp holder is de-energized, compare DE 44 45 223 A1.
  • the invention is based on the object in one Generic device with an integrated ignition device mechanical blocking of the socket arranged on the housing Provide against plugging in the supply connector as long as how to use a recorded gas discharge lamp the bayonet connection of its base is not in the locking rotational position located.
  • the in the device housing movably arranged latch in the plug area of the If there is not a socket for the supply plug with its base inserted in the lamp holder gas discharge lamp is rotated into the locking rotational position. As long as how the latch blocks the plug area of the socket, the supply connector cannot be used in it. The electrical connection of the ignition device is thus interrupted, and it's the touchable contacts in the Lamp holder for the electrical supply of the gas discharge lamp accordingly free of tension. For one, it can Assignment between the rotational position of the lamp base and the bolt must be hit so that when inserted into the socket Supply plug a twisting of the gas discharge lamp in the unlocked position is not possible.
  • a preferred embodiment of the invention is to be overcome in the plug area of the socket Provide stop, behind which the bolt in its locking pivot position intervenes so that not by pressing of the supply plug into the socket of the latch in its unlocking position can be pushed back. through a form fit that can be canceled by targeted manipulation the bolt can be in its locking end position are particularly well secured.
  • FIG. 1 further illustrates one arranged in the housing 1 Lock ring 5, which the insertion opening 2 below the Surrounds the outer wall 3 of the housing 1. Consequently corresponds the inner diameter of the locking ring 5 the diameter of the Insert opening 2, and the locking ring 5 is also on the bayonet locking of the base 17 of the gas discharge lamp 15 adjusted.
  • it has axially parallel grooves 6 for the bayonet pin 18 on the lamp base 17, the in the unlocking rotational position with the bulges 4 on Edge of the insertion opening 2 in the area of the housing outer wall 3 are in line. This unlocking position is shown in Fig. 1.
  • the bayonet lock requires it to be inserted into the insertion opening 2 inserted gas discharge lamp 15 around a predetermined Rotate angle clockwise. In the locked position then reach under the bayonet pin 18 on the lamp base 17 the housing outer wall 3 outside the bulges 4, causing the axial securing of the gas discharge lamp 15 is made. When turning the gas discharge lamp 15 from the unlocked position to the locked position is on the bayonet pin 18 on the lamp base 17 the locking ring 5 is taken along, it is accordingly in the housing 1 rotatably mounted.
  • the electrical lead to the ignition device and the one arranged in it Ignition device takes place on the outside of the housing 1 arranged socket 9 with a plug area 10 in which a lead connector 11 can be added.
  • a plug area 10 in which a lead connector 11 can be added.
  • the socket 9 has Mating area 10 has a side opening 12 which for the Passage of a bolt 13 is provided.
  • This bar 13 is part of the locking ring 5, it stands on the locking ring 5 outside in front, being a relative to the radial direction is slightly inclined counterclockwise.
  • the locked rotational position of the locking ring 5 is the locking bolt 13 so far penetrated into the plug area 10 of the socket 9, that the supply plug 11 is not inserted here can.
  • FIG. 2 in which the supply connector 11 in front of the insertion opening Socket 9 is shown arranged.
  • the supply connector is located 11 in the plug area 10 of the socket 9 and then over the lamp base 17 by taking it over the bayonet pins 18 the locking ring 5 from its locking position, as can be seen above all in Fig. 4, in its unlocked position rotated, which is shown in Fig. 2, then is via the bolt 13 on the locking ring 5 of the supply connector 11 ejected from the socket 9.
  • the locking ring 5 is the position to be understood in which the bulges 4 at the edge of the insertion opening 2 not with the receiving grooves 6 of the locking ring 5 in alignment, so in the bayonet connection for securing the lamp base 17 is made.
  • a stop for the bolt 13 14 In the plug area of the socket 9 is a stop for the bolt 13 14 provided. This stop prevents in the locking position of the locking ring 5 by pressing the plug 11 into the socket 9 via the bolt 13 of the locking ring 5 can be rotated into the unlocked position. Accordingly, the latch engages when the locking ring 5 is turned 13 in the locking position behind the stop 14, which can only be overcome by deliberate manipulation can. Consequently, the latch 13 also takes its engaged position a locking position at the stop 14, which corresponds to the locking position of the locking ring 5.
  • the bolt 13 can overcome the stop 14 is the locking ring 5 together with the one sitting thereon Bolt 13 displaceable in the direction of the axis of the insertion opening 2, and it is loaded by a spring that the locking ring 5 towards the front housing wall 3 suppressed.
  • the spring mentioned is not shown in the drawing. In the unlocked position, therefore, must also be added twisting the locking ring 5 over the lamp base 17 an axial pressure towards the inside of the housing 1 the lamp base 17 are exerted, thereby locking the latch 13 to disengage from the stop 14.
  • FIG. 3 and 4 show details of the Gas discharge lamp 15. It has a burner 16 which connects in the axial direction to the lamp base 17.
  • the Lamp base 17 has a radially projecting base plate 20, the handling of the gas discharge lamp 15 in particular for the above-mentioned indentation towards the inside of the housing 1 and when rotating between the Unlocking position and the locking position facilitated.
