Definitions

  • the invention relates to a lamp socket for double ended fluorescent lamps according to the preamble of claim 1.
  • Lampholders of the aforementioned type are usually used for the electrical connection of double-capped fluorescent lamps - in particular fluorescent tubes with G13 sockets - each having on the front side two arranged parallel to the Lampenlteilsachsplatz socket contact pins.
  • the socket housing as well as the rotor each have an insertion opening or an insertion gap, which, brought into cover, allow the insertion of the lamp in the socket. When inserted, the socket contact pins are only in the area of the rotor.
  • the lamp For electrical contacting with housing contacts arranged in the housing, which are usually designed as spring contacts, the lamp is rotated with entrainment of the rotor, to achieve the contact position usually a 90 degree rotation is required.
  • the rotor For detecting the defined contact position for the user and for the safe whereabouts of the lamp in this contact position, the rotor has at least one detent position.
  • DE 915204 discloses, for example, a locking plate arranged below the rotor, the locking cams of which are directed towards the rotor engaging in rotor-side latching recesses.
  • GB 591676 On the other hand, spring contact, which is open in a V-shaped manner at the rotor center and in which the base contact pins are held in a snap-action manner after the rotor has been turned by 90 degrees, starting from the insertion position, is shown.
  • a similar solution to identify the defined contact position shows JP 2002-100450 ,
  • JP 2004/134089 A Apply control pin on the outside circumference of the rotor of the socket, which engage in the insertion position of the rotor in recesses of the socket contacts to stabilize the insertion position.
  • the control pins spread the socket contacts to prevent premature contact with the socket contacts.
  • the recesses serve as contact areas of the socket contacts and are applied to the socket contacts.
  • JP 4357685 B a generic version is shown, in which the socket contact has a control tip and a contact recess. While the control tip spreads the socket contacts at rotor rotation and engages in the contact position in a rotor-side locking gap, the socket contact pins are in the contact position in the contact recesses. The control blades have no contact with the socket contact pins in any rotor position.
  • the lamp replacement is carried out not only by trained personnel, but usually by users who are not informed in detail about the technical structure of such a lamp socket. Since fluorescent lamps are at best moderately warm during operation and lighting systems are often not completely switched off If replacing a defective lamp often happens under applied voltage. As a result, the replacement lamp ignites as soon as the socket contact pins touch the socket contacts for the first time. In the versions of the prior art, the contact between socket contact pins and socket contacts usually takes place well before the defined contact position, in which a secure fit of the lamp in the socket and a defined contact, eg with a certain contact contact pressure between the socket-side contacts and the socket-side contact pins is guaranteed. Due to lack of knowledge of the user remain the fluorescent lamps in an undefined contact position, since the ignition of the lamp suggests a proper function.
  • the object of the invention is to provide a lamp holder for a fluorescent lamp, in which it is ensured that the fluorescent lamp is basically rotated in the defined contact position.
  • each socket contact has a spring leg with contact area pointing to the rotor center, which serves for contacting with one base contact pin of the lamp in the defined contact position and shaped otherwise is that other areas the socket contact as the contact area in each position of the rotor are contactless to the socket contact pins.
  • socket contacts usually arcuate or roof-shaped, so are designed so that the socket pins of the lamp in a wide range of the partial arc that you describe by turning the lamp and rotor until reaching the defined contact position on
  • the socket contacts function insecure concern, such a system is inventively avoided.
  • the spring leg on a substantially conical or circular arc-like directed to the rotor center leg portion which forms the contact area.
  • the contact area has a contact point in its vertex with a flattening or depression for the conditioning of the base contact pin.
  • the contact area forms a contact tip in its apex, the shape in such a way adapted to the width of the rotor-side insertion gap, that they for the purpose of compensation of tolerances of the socket contact pins can at least partially penetrate into the insertion gap.
  • a particularly preferred embodiment is characterized in that the rotor has externally circumferentially arranged control projections with control surfaces which cooperate with spring elements arranged on the housing side and urge the rotor into the defined contact position after exceeding a dead point achieved by rotation and by building up a spring tension.
  • the rotor has externally circumferentially arranged control projections with control surfaces which cooperate with spring elements arranged on the housing side and urge the rotor into the defined contact position after exceeding a dead point achieved by rotation and by building up a spring tension.
  • the spring element is a leaf spring element formed by the socket contact, in particular the spring leg is designed as acting on the rotor leaf spring element.
  • the spring force of the spring leg which both urges the rotor in its defined contact position and the contacting of the socket contact pins, can be increased by the socket contact forms a resilient support leg, with the free ends of the spring legs and support legs overlapping each other supporting.
  • the contact area of the spring leg facing the rotor center forms a control cam and interacts with the control surfaces of the rotor in such a way that the spring leg formed as a leaf spring element is splayed as the rotor rotates to build up a spring tension until the dead center is reached and the spring tension is reduced pushes the rotor into the defined contact position.
  • a lamp socket is generally designated by the reference numeral 10.
  • the lamp socket initially comprises a socket housing 11 with a base 12, which serves for fastening the lamp socket, for example in a lamp housing.
  • the base 12 opposite the socket housing 11 has a slot-shaped insertion opening 13, also referred to as insertion slot 13, which in the in Fig. 1 shown mounting position in an insertion gap 14 of a socket housing 11 rotatably mounted rotor 15 opens.
  • the rotor 15 itself is mounted in a cup-shaped socket housing cutout and is captively defined by locking tabs 16 in the socket housing 11.
  • Fig. 2 the lamp holder 10 is shown with rotor 15 rotated into the defined contact position. Only in section shown base contact pins 19 are directed towards the rotor center 20 contact blades 36 of in Fig. 3 shown socket contacts 22 at. For this purpose, the rotor 15 was rotated from the mounting position by 90 degrees in the defined contact position.
  • Fig. 3 shows the arranged within the socket housing 11 socket contacts 22, here in a two-part design for so-called rapid-start variant.
  • a one-piece design of the socket contacts 22 for so-called instant-start variant is in Fig. 10 shown.
  • the following description reads - apart from the Bipartite of in Fig. 3 shown socket contacts - identical to the Fig. 10 ,
  • the socket contacts 22 are punched parts of a sheet and mirror-symmetrically located within the socket housing 11.
  • Each socket contact 22 initially has a one-piece holding leg 23, which receives in its shape approximately the inner contour of the socket housing 11 and with the help of which the socket contact 22 is supported on the socket housing 11.
  • the holding limb 23 lies partially against the inner surface of the socket housing wall, in particular with its end sections and a middle section. Characteristic of the holding leg 23 is that it is far out of reach of the guided through the rotor 15 base contact pins 19 a fluorescent lamp.
  • the contact leg of the socket contact 22 is divided into two parts and forms a spring leg 24 and a support leg 30.
  • the flattened in its apex formed contact portion 26 is the only area of the spring leg 24, which in a the socket pins 19 imposed by the rotor 15 circular arc-like path 27 (exclusively in Fig. 1 shown as a hatched area) protrudes. Only this relatively small contact region 26 thus enables an electrical connection between the socket contact pins 19 and the socket contacts 22.
  • the spring leg 24 is configured as a one-sided connected to the holding leg 23 leaf spring element, the free end 28 is overlapping at the free end 29 of a resilient support leg 30 is supported.
  • the spring-elastic support leg 30 makes it possible to apply higher spring restoring forces on the spring leg 24.
  • Fig. 4 again shows the socket housing 11, but in an exploded view.
  • the rotor 15 is shown here separated from the lamp holder 10.
  • wing-like projections 32 are shown, which cooperate with the respective leg portion 25 of the spring leg 24 control surfaces 33.
  • the projections 32 extend the outer peripheral contour of the rotor shaft 34 in some areas approximately oval, wherein the control surfaces 33 in the region of the insertion gap 14 as sliding to the rotor center 20 sliding surfaces 35th are formed.
  • the protrusions 32 are consequently located directly adjacent to both sides of the insertion gap 14.
  • Fig. 5 to 8 each show a longitudinal section through the socket housing 11 of the lamp holder 10 according to Fig. 1 , wherein in each case the position of the rotor 15 differs.
  • Fig. 5 the rotor position corresponds to that of the Fig. 1 ,
  • the rotor 15 is in the so-called assembly position.
  • the insertion opening 13 of the socket housing 11 and the insertion gap 14 of the rotor 15 come into coincidence, so that socket pins 19, not shown here, can be inserted into the lamp socket 10 and lie in the area of the rotor 15.
  • the leg portion 25 of the spring leg 24, which forms the contact region 26, abuts the outer circumference of the rotor 15.
  • the conically tapered contact tip 36 which in the present case forms the contact region 26, not only fulfills the contact function but also a control function as a control cam.
  • the contact region 26 / the contact tip 36 slides over the control surfaces 33 of the control projections 32 and displace the spring legs 24 from its rest position in the direction of the housing wall 37, as in Fig. 6 is shown.
  • the free end 28 of the spring leg 24 is supported on the support leg 30, which is also displaced out of its rest position in the direction of the housing wall 37 in a row.
  • On the legs 24 and 30 of the socket contact 22 made of a resilient material so spring restoring forces are applied, which urge the legs 24 and 30 back towards the rotor center 20.
  • the conically tapered towards the rotor center 20 contact tip 36 is formed flat in its apex, but it is quite conceivable that the contact group 36 has a pot-like depression in its apex region. In this depression, the base contact pin 19 eino or engage, so that even the smallest rotational backlash of the rotor 15 is reliably avoided in the defined contact position.
  • a play-free locking between socket housing 11 and rotor 15 may be provided in the defined contact position by appropriately adapted Gehotteil- and / or rotor geometries, which prevents a possible rotational play of the rotor 15.
  • control projections 32 extend the outer circumference of the rotor 15 in the region of the insertion gap 14 such that they deflect the spring leg 24 in any position other than the defined contact position so far that a contact between the spring leg 24 and socket contact pin 19 is excluded , Only the contact tip 36 is so tapered in the direction of the rotor center 20 that it is able to penetrate after overcoming the dead center of the rotor to rest on the base contact pin 19 in the insertion gap 14.
  • the housing cutout in which the rotor 15 is mounted, in the region of an assembly position through the insertion opening 13 and the insertion gap 14 extending axis cutouts 40.
  • this can, if the insertion opening 13 and the insertion gap 14 are brought into line, are inserted into the housing cutout.
