Definitions

  • the invention relates to a socket arrangement for an electric lamp, namely a socket arrangement, which can be fastened to an external connection led out of the lamp, without the need for cement or putty.
  • Electric lamps usually have a base, which for receiving in a lamp socket and for connection to an external power supply.
  • a lamp arrangement in which an electric lamp has a socket, through which it is received in a lamp socket.
  • the outer dimensions of the socket are usually mandatory and comply, for example, with the R7s, RX7s, KX10s or KY10s.
  • the latter pedestals are used, for example, in high-pressure mercury lamps where they end up crushed at opposite end portions of the quartz glass bulb cemented or cemented over which project the outer terminals of the lamp. Such an arrangement is described for example in DE 2718735 C2.
  • the cementing of the lamp base has several disadvantages. For one thing must at the lamp manufacturer, mixing devices are provided to freshly prepare the cement because it has only a limited processing time before it sets. Around To slow this setting process, the cement must be cooled and also the humidity be regulated. Because of the limited processing time of the cement can each only relatively small amounts of cement are prepared for processing, otherwise the Amount of unused cement and thus the amount of residual waste is too large. Even then, however, residual waste still accumulates, which must be disposed of.
  • the finished product obtained after drying the cement is not perfect satisfactory. For example, it may be due to the rigid attachment of the base on Squeezing the electric lamp to get tension, the worst case for Breakage of the lamp bulb can lead. Because the cement is porous and hygroscopic properties has been, were repeatedly corrosive to the embedded in the cement external connections the lamp is observed. The stability of the cemented base also leaves much to be desired left. The cement begins to crumble over time, resulting in dirt on the one hand Lamp environment and on the other hand to a deteriorated mounting of the lamp cap on Piston leads.
  • EP 1 009 012 A1 discloses an electric lamp for a motor vehicle headlamp with a Pinch and over this protruding external connections, which are inserted into a carrier sleeve are formed as part of a lamp cap.
  • a pressure spring is disclosed, which holds the base to a reflector opening formed as a lamp holder.
  • a metallic, rigid bracket fixes the pinch of the lamp in the base.
  • DE 199 51 873 A1 discloses a discharge lamp with on the inside of the outer wall the lamp vessel arranged electrodes, which partially out of the interior of the lamp are led to the outside.
  • the outwardly led electrode sections have in addition to the electrodes to this fitting, also outwardly guided wall sections of Lamp on.
  • the electrode sections are inserted into a base sleeve, wherein the inner wall the base sleeve is designed as a guide for the electrode sections, i. the electrode sections lie against the inner wall.
  • the base sleeve has electrically conductive spring elements which protrude into the interior of the base sleeve and a spring force on the electrode sections, from the inside to the outside in the direction of the base inner wall, apply. adversely Here is that the spring elements do not secure the discharge lamp against pulling out, but sondem only ensure the installation of the electrode sections on the lamp base and thus no solid and permanent attachment of the lamp in the socket is achieved.
  • EP 0 547 683 A1 describes an electric lamp with a led out of the lamp External terminal, which engages in an electrically conductive contact element, which in a Lamp socket is arranged.
  • the external connection is crushed with the contact element and / or welding mechanically connected.
  • Special openings must be provided in the base sleeve, through the appropriate Tools can be introduced so as to establish the mechanical connection. Therefore This manufacturing process is quite expensive.
  • the object of the invention is to provide such a socket arrangement.
  • the invention thus relates to a base assembly for an electric lamp, which consists of a electrically insulating base sleeve and an electrically conductive contact element.
  • the Base sleeve has a base cavity in which the contact element is inserted.
  • the contact element has at least one cavity for receiving one of the electrical Lamp led outward connection.
  • the contact element has at least one into the cavity projecting resilient retaining projection for engagement with the outer terminal.
  • the at least one resilient retaining projection is either as resilient mounted latching projection, which can be latched into a latching recess of the outer terminal or as a tongue or strip-like projection, which is obliquely from, seen radially, outside to inside in the Cavity extending toward the socket side, formed.
  • the base assembly according to the invention is constructed so that the base sleeve, the contact element and the external connection only have to be pushed into each other and thereby jammed against each other, so that no cement or other additional for fixing Fasteners are needed.
  • the external connection of the electric lamp is only held by the at least one resilient retaining projection in the socket assembly.
  • a resilient retaining projection in the context of this invention basically everyone should be elastic deformable retaining projection, regardless of material or shape understood.
  • the term includes such holding projections, which form a non-positive holder lead the external connection in the cavity of the contact element.
  • the resilient retaining projection also to a positive attachment lead, for example by a locking lug form-fitting in a recess in the outer terminal intervenes.
  • Elastic retaining projections can also be understood as meaning a multiplicity of teeth which protrude into the cavity and act like small feathers. Possibly These teeth can not only when inserting the external connection in the cavity elastic, but also plastically deform. They dig themselves into the outer surface of the External connection and resist thereby and by their shape pulling out of the outer terminal out of the cavity. Burrowing into the surface of the External connection can also with other forms of resilient retaining projections attachment improve in the contact element.
  • the invention can in principle be applied to any type of socket and in particular on those pedestals, which previously attached using cement to the lamp envelope like the sockets of R7s, RX7s, KX10s and KY10s mentioned earlier.
  • the outer ones Dimensions of the electrically insulating base sleeve of the socket arrangement according to the invention are then executed according to these standards.
  • the base cavity of the base shell be as Through opening with a facing in the direction of the lamp socket socket-side opening and a bulb-side opening facing the lamp is executed.
  • the pedestal cavity is suitably designed so that it is for substantially positive reception of the contact element is suitable. In this way, a tilting of the contact element in the base sleeve can be prevented.
  • the base sleeve preferably has at least one in the base cavity projecting stop for the contact element. Accordingly, the contact element at least one over its outer circumference projecting projection to rest on this Stop on. Through this stop and the associated projection of the contact element It is determined how far the contact element can be inserted into the base cavity.
  • the base sleeve has in its base cavity at least one return to System for a latching projection which is formed in the contact element. Is the contact element in inserted the desired position in the base cavity, the locking projection of the contact element engages at the return of the base sleeve and secures the contact element so against further shifting. It is particularly preferred when latching projection and return in the socket sleeve have substantially the same width, since in this way the contact element In addition, it can be secured against lateral twisting. It is particularly useful if the pairs stop / projection and return / locking projection in combination with each other be used, so that after the engagement of the locking projection, the contact element neither to the lamp-side opening nor to the socket-side opening of the socket sleeve on can be moved.
  • the latching projection is in the form of a protruding over the outer circumference of the contact element formed resilient catch.
  • This can be useful by shaping out a Part of the contact element are formed. For example, a partial section becomes dome-like bulged outward, or a section is bent outwards so that the detent wedge-like manner with the tip in the direction of insertion stands up.
  • the external connection already be a resilient retaining projection sufficient. Is appropriate then at least on the side opposite the retaining projection side of the cavity a fixed lateral stop for the external connection available, against which this through the resilient retaining projection is pressed.

Will the external connection inserted into this cavity, the tongue or strip-like projection to the outside bent. The front edge of the projection comes on the outer circumference of the outer terminal to lie, and the inclination of the protrusion prevents the external connection from the cavity of the contact element can be pulled out again.
  • a detent recess as an annular groove in the outer terminal to be designed to pull out the external connection continues to complicate. In general, the external connection but already secure without an additional recess.
  • a sharp end edge of the Holding projection can improve the attachment, as this edge in the outer surface of the Terminal can dig in and so further pulling out of the terminal difficult.
