Definitions

  • the invention relates to a lampholder that can be installed in a luminaire for at least one lampholder for accommodating a two-pin base fluorescent lamp according to the preamble of claim 1.
  • the two-pin fluorescent lamp to be converted into a single-pin fluorescent lamp, as can be seen, for example, from DE-OS 31 36 961 or DE-PS 36 02 931.
  • the two-pin base is removed and a single-pin base is placed on the glass tube in a certain way, whereas in the version according to DE-OS 36 02 931, a clamping block is placed on the two pins at each end , which short-circuits the two pins and to which a single pin for a single-pin socket is attached.
  • the lamp can be designed so that a two-pin base fluorescent lamp can be used without conversion or base.
  • a rotary socket for a two-pin base fluorescent lamp has become known from DE-OS 36 38 507.
  • both pins are short-circuited and are connected to a pin which is arranged displaceably in a socket housing and which, when rotated, slides on an inclined surface, so that in a first position this pin is in contact with and in one of the two pins of the two-pin base fluorescent lamp the second position is out of contact with this pin.
  • pressure-resistant encapsulation is required, because in the so-called switched-on position there is an electrically conductive connection between the pin of the lamp, the contact pin and a contact surface, which is part of a contact bolt which passes through the wall and has a connecting conductor connected to its outer end is.
  • a version for a fluorescent lamp which has become known which has a socket body which is designed both for receiving the two pins of a two-pin base fluorescent lamp and for receiving the single pin of a single-pin base fluorescent lamp.
  • this socket carrier or socket body has two diametrically opposite small holes for receiving the pins and a larger hole in the middle for the single pin. So-called multi-contact blades are located in the holes.
  • Such sockets can be attached to a holder, as described in DE patent application P 39 08 619.4.
  • the object of the invention is to further improve the holder of the type mentioned for a two-pin base fluorescent lamp.
  • the socket has a socket housing made of two latched housing parts, of which the upper housing part is attached to the socket carrier and rotatably receives the contact element carrier.
  • the contact element carrier has two openings into which C-shaped contact elements are inserted, so that these contact elements receive the two pins of the fluorescent lamp.
  • a further embodiment of the invention can be found in the characterizing part of claim 2.
  • This configuration serves to accommodate a two-pin base fluorescent lamp, the rotatability of the contact element carrier serving to ensure that the fluorescent lamp can no longer be removed from the socket.
  • the C-shaped contact elements are connected to each other according to claim 3 so that they form a unit, at the same time flags are provided, which are provided to limit the rotational movement when rotating the fluorescent lamp with the contact elements.
  • the socket housing is formed from an upper housing part and a lower housing part
  • one of the two housing parts here in particular the upper housing part, can be integrally formed on the holder and thus form part of the holder, so that the lower housing part only has to be snapped onto the holder, which means that Snap the lower housing part to the frame carrier, the entire housing is formed.
  • the latter embodiment in particular has great advantages for the simple and problem-free manufacture of a frame carrier according to the invention.
  • FIGS. 1 and 2 show two views of a mount support 10 which, as can be seen from FIGS. 1 and 2, has a vertical support wall 11 and a horizontally extending support wall 12.
  • the exact structure of the holder is of secondary importance for understanding the invention.
  • the design of the vertical support wall 11 is essential since fluorescent lamps are attached to these sockets (see below).
  • FIG. 4 shows a sectional view through a socket according to the invention, which has the reference number 13 in its entirety.
  • the socket 13 comprises a socket housing 14 which is composed of an upper housing part 15 and lower housing part 16.
  • the upper housing part 15 is thereby on the vertically extending Molded support wall 11 that it has the shape of a cup-shaped body formed from the support wall 11 or is formed.
  • a total of three upper housing parts 15, which are integrally formed on the carrier wall 11, can be seen in FIGS. 1 and 2.
  • the lower housing part 16 (see FIG.
  • the lower housing part 16 has a circular cylindrical section 21, on the free edge of which a radially extending flange shoulder 22 is formed, on the edges of which the detents 17 and 18 connect perpendicular to the edge flange.
  • the section 21 has a type of bottom 23 through which the section 21 is delimited on the end face of the section 21 opposite the edge flange 22.
  • This base 23 is followed by a further angular section 24, on the free end of which a shell-like extension 25 is formed.
  • the bottom 23 has an opening 26 which widens into the interior 27 of the section 24, so that the inside diameter of the opening 26 is smaller than the inside diameter of the interior 27.
  • the section 24 is square in cross-section in its outer circumference, it also has the interior 27 has an inner cross section adapted to it.
  • a connector 28 is inserted, which is divided into two areas 29 and 30 by a constriction 31;
  • the opening 26 projects into this constriction 31 with a strip 32, so that the connecting piece is held in the lower part 16 in the region of the constriction.
  • Section 29 is in the form of a tubular cylinder, so-called multi-contact blades 33 being used in the interior of section 29.
  • the area 30 has an internal thread 34 into which a clamping screw 35 is screwed, it being possible for a connecting line 36 to be clamped between the free end face of the area 30 and the screw head 37 with a washer 38.
  • a clamping element carrier 40 which is shown in more detail in FIG. 5, is inserted into the upper housing part 15.
  • the clamping element carrier has a circular shape in cross-section, with an upper surface 41 (see drawing FIG. 5), on which segments 42, 43 like segments of a circle are placed at a distance from one another.
  • the clamping element carrier 40 has a substantially rectangular, axially extending opening 44 which is bridged by a bridge 45 running between the attachments 42 and 43, so that clamping element receiving spaces 46 and 47 are formed on both sides of this bridge.
  • grooves 48 and 49 run in the radial direction, which are aligned with one another and whose depth, measured from the upper surface 41 and designated by t, corresponds approximately to the length L of a pin 50 of a two-pin base fluorescent lamp 51.
  • a groove 52 which is aligned with the grooves 48 and 49 and has the same depth.
  • the clamping elements 53 which are shown in FIGS. 6 to 8, are inserted into the terminal receiving spaces 46 and 47.
  • the clamping elements 53 have a clamping element base 54, on which the actual, C-shaped clamping parts 55 and 56 are molded.
