Definitions

• the invention relates to a lamp socket with an insulating body and in it provided, in particular screwless, lamps contacts assigned terminals for network ladder, the terminals by ladder Insertion openings and, if necessary, auxiliary openings for a release tool are accessible, which in a in particular the bottom wall of the insulating body are provided.
• Task at hand Invention is a lamp holder in the upper term of the protection claim 1 outlined in more detail Kind to provide that the terms the so-called "Protection Class II" for lights fills. So far suitable lamp sockets for this were only feasible with an additional Ab top cap, a so-called “socket dome”. The opposite is intended with the present invention a Lamp holder will be made available that overall formed in one piece or in one piece can be.
• the invention solves this problem in the first place Line in that the conductor insertion openings and the auxiliary openings of ange on the insulator molded insulating collar are surrounded, their outer end faces of live parts (Clamp) a distance of at least 8 mm hold.
• the insulating collars are in one piece and cohesively provided on the insulating body, with which a one-piece version is realized that the necessary creepage and clearance distances represents.
• Each insulating material collar forms a closed-rimmed channel.
• the channels below are also a great advantage joint use of wall parts close-together densely arranged. This leaves one accordingly close assignment of the network connections to.
• the one in each cable connection channel existing gradation forms a longitudinal stop for the end face of the hose cover.
• hose sleeves Ladder the hose covers on the Basisiso
• the conductor can be moved easily.
• a Fixation comes on the one hand by clamping the additional insulating hose nozzle in a cable load, clamp or the like. in question while now according to the invention, on the other hand, one axial support on the step of the channel guaranteed is performing.
• the stage also offers the advantage of that only the one provided with the basic insulation Head end section further into the socket can be performed. This is a targeted one lead the head, especially his isolated end possible.
• a total of 10 designated lamps version essentially consists of an ISO lierstoff Archives 11 made of porcelain or in particular their plastic as well as provided therein, ins special screwless, terminals 12, 13, which lamp contacts 14, 15 are assigned.
• in the Bottom 16 of the insulating body are located, as usual, conductor insertion openings 17, as well also for each terminal 12, 13 an auxiliary Opening 18 for inserting an auxiliary tool like screwdriver blade 19 to the intended one Re-loosen a connection terminal 12 or 13.
• Embodiment is also any type terminal 12, 13 from the side by a Jacket opening 20 of the insulating body 11 to accessible.
• Luminaire protection class II In order to comply with the requirements for an application in the Luminaire protection class II prescribed creep and clearances are the conductor insertion openings 17 and the auxiliary openings 18 of insulating material collar 21, 22 surrounded.
• This insulating collar each form a closed-edged channel from, and their outer faces point from live parts (terminals 12, 13) a minimum distance of 8 mm.
• the two with the terminals 12, 13 to connecting power line 24 consist of one stripped conductor end 25, one of these against via recessed basic insulation 26 as well additional insulation in the form of a Basic insulation pushed out tubular sleeve 27 soft elastic plastic material.
• While the basic insulation 26 usually has an outside diameter of about 2 mm, is the outer diameter of the hose sleeve 27 about 4 mm.
• The are adapted to this diameter Channels formed by the insulating collar 21 graduated. They each have one in the through knife larger outer portion 28 and one inner section 29 smaller in diameter on.
