Definitions

  • the invention relates to a lamp base according to the preamble of patent claim 1 and an electric lamp with such a lamp base.
  • the lamp base according to the invention has at least one power supply and sealing means for sealing the lamp cap in the region of the at least one NEN power supply, said sealing means comprise at least one of the following feature combinations A, B or C:
  • An elastomer or rubber which surrounds a portion of the at least one power supply in a form-fitting and annular manner, wherein this elastomeric or rubber-enclosed portion of the at least one power supply is positively embedded in a plastic injection-molded part of the lamp cap,
  • a surface region of the at least one power supply which is provided with a profile or a roughening, wherein this region of the at least one power supply is embedded positively in a plastic injection-molded part of the lamp cap,
  • Each of the aforementioned feature combinations A, B or C allows the sealing of the lamp cap in the region of the power supply lines already during the production of the plastic injection-molded part of the lamp cap.
  • the at least one power supply annular and positive surrounding elastomer or rubber (feature combination A) is compressed during the injection process during the production of the plastic injection molded part and lies close to the power supply and the plastic material of the plastic injection molded part. As a result, the lamp cap is sealed in this area against the ingress of moisture.
  • a region of the at least one current feed embedded in a plastic injection-molded part in a form-fitting manner is provided with a surface profile or a roughening (combination of features B).
  • a portion of the at least one power supply embedded in a form-fitting manner in a plastic injection-molded part of the lamp cap is included Slots (feature combination C) provided. This extends the creepage distance for penetrating moisture or gases and thus increases the sealing effect.
  • a primer is provided to increase the sealing effect.
  • the primer is preferably arranged as an intermediate layer between the power supply and the elastomer or rubber or applied to the provided with the surface profile or slots portion of the at least one power supply.
  • the primer increases the adhesion of the plastic material of the plastic injection-molded part to the power supply and compensates for the air gap arising during shrinkage or shrinkage of the plastic material.
  • the aforementioned sealing means are arranged on a portion of the at least one power supply formed as a sheet metal part.
  • the sheet metal part allows secure anchoring of the power supply in the plastic injection molded part.
  • Figure 1 shows a longitudinal section through a plastic injection molded part of the lamp cap according to the first embodiment of the invention
  • FIG. 2 shows a cross section through the plastic injection-molded part depicted in FIG
  • Figure 3 is a plan view of a power supply of the illustrated in Figure 1 lamp cap
  • Figure 4 is a side view of the power supply shown in Figure 3
  • Figure 5 is a plan view of a power supply according to the second embodiment of the invention.
  • Figure 6 is a side view of the power supply shown in Figure 5
  • Figure 7 is a plan view of a power supply according to the third embodiment of the invention
