Definitions

  • the two contact strips include a section projecting from the holder body and serving the electrical connection.
  • Two resilient legs extend in about the longitudinal axis of the holder. The resilient legs are angularly bent substantially 90 relative to the first section within the range of the glass base cap to be held between the resilient legs.
  • the first section of each of the contract strips has a longitudinal slot extending therethrough up to the connecting stay, and the entire contact strip is of increased material strength, the first sections projecting from the holder body constitute a plug for a socket sleeve.
  • the present invention relates to an embodiment of a holder for electrical lamps with a glass base cap, in particular for small lamps, including a cup-like body consisting of insulating material and two contact strips inserted therein, which have a section projecting from the holder body and serving the electrical connection and two resilient legs extending in about the longitudinal axis of the lamp holder, within the range of the glass base cap.
  • the contact strips are made with a relative thin gauge of material, whereby above all a good resilience is to be obtained.
  • the connection lugs projecting from the housing or the holder body, respectively, as plugs also, the latter must be reinforced.
  • the connection lugs are folded over, so that the contact strips are arranged in a double arrangement. Thereby the free inner ends are angularly bent, whereby tongues are created which support themselves against the bottom of the housing and thereby secure the contact strips against a displacement.
  • this embodiment still needs improvement, since the folding of the cold beaten, thin material of the connection lugs or plugs, respectively, is combined with comparatively high costs by reason of the required expensive tools and the use of high quality material. Moreover, the danger of fractures of material at the folds exists.
  • FIG. 1 is a cross section of the holder body with insetted contact strips, in accordance with the present invention, taken along the lines A-A of FIG. 2;
  • FIG. 2 is a top plan view of the holder body shown in FIG. 1;
  • FIG. 3 is a side elevation of the contact strip
  • FIG. 4 is a bottom plan view of the holder body with contact strips.
  • the holder body 1 has two diametrically oppositely disposed openings 2, into which contact strips 3 and 4 are inserted from above.
  • the contact strips 3 and 4 having throughout equal strength of material, are bent over for a right angle at their longitudinal sides over the smaller part of their length, so that, respectively, two legs 5 and 6 are created, which legs 5 and 6 are so far bent towards each other, that a sqeezed glass base cap 7 of a lamp 8 is held by the legs 5 and 6 with a resilient clamping action by pressure locking.
  • the contact strips 3 and 4 are each provided with a longitudinal slot 10 extending over the entire length up to a remaining connection stay 11.
  • the plugs 13, projecting out of the housing of the holder body 1, are equipped each with two tabs 15 arranged close below the bottom of the housing, which tabs 15 can be bent to the shape shown in FIG. 4, after inserting them, so that they act as abutments, which secure the contact strips against displacement in the one direction.
  • the recess 17 in the plugs 13 serves as opening for the connection of the plugs with a socket sleeve (not shown).
  • the plugs 13 can be used also for soldering connections.
  • a holder for electrical lamps with a glass base cap, in particular for small lamps, comprising a cup-like holder body of insulating material, and
  • each of said two contact strips including a first section projecting from said holder body and serving the electrical connection and two cooperating resilient legs extending in about the longitudinal axis of said holder for holding a glass base cap of a lamp therebetween,
  • each of said contact strips being angularly bent substantially 90 relative to said first section within the range of said glass base cap of a lamp to be held between said resilient legs said first section of each of said contact strips having a connecting stay at an end thereof remote from said two resilient legs, and a longitudinal slot extending through each of said first sections from a point spaced from said end through the other end of each of said first sections, and
  • each contact strip being made entirely of strengthened material and said projecting portions of said first sections and said connecting stays constituting a plug.
  • the holder as set forth in claim 1, which includes two tabs arranged at the edges of said first sections projecting from said holder body, closely to the bottom thereof, and
  • said tabs are bent out of the surface of said first sections and constitute abutments for securing of said contact strips.
