Definitions

  • the present invention relates to a flashlight with a flashlight housing and arranged in an end cap tactile, detent or rotary switch, which has a switch housing, in which a first and a second contact element engage.
  • a disadvantage of the circuit arrangements, as they are realized in conventional flashlights, is firstly that the current is passed over a multiplicity of contact areas, with a corresponding contact resistance dropping over each contact area.
  • a self-induction voltage is induced by the current flow within the coil spring, which counteracts the actual current flow. Both result in a lower voltage dropping above the light source, whereby the luminous intensity of the light source drops markedly.
  • the first contact element is a leaf spring, which is directly on the electrically conductive flashlight housing or directly against the electrically conductive and detachably connected to the flashlight housing end cap is in contact-contact, wherein the second contact element is formed outside of the switch housing as a bent leaf spring and is directly connected to a power supply.
  • the light source is a light-emitting diode (LED) and, as a power supply, at least one battery or accumulator, i. at least one rechargeable battery is provided.
  • battery packs may be used from a plurality of batteries connected in series.
  • the use of an LED as a light source reduces power consumption, so that more energy is available to generate light.
  • the switch is arranged in a guide housing having recesses through which the contacts of the switch project radially or frontally outwards, where they are formed as leaf springs and form electrically conductive contact surfaces.
  • the guide housing is preferably designed as a plastic injection molded part, whereby the production costs can be kept extremely low.
  • the guide housing is preferably designed in two parts and preferably consists of two rudzylinderschalenförmi- gene sub-segments. To insert a switch into a guide housing, first the sub-segments are separated from each other and the switch is in an output placed within a subsegment.
  • the sub-segments are reassembled into a guide housing, whereby the switch is mounted and held within the guide housing.
  • the contacts of the switch can be led out of the guide housing to allow electrical contact
  • groove-shaped recesses are provided in at least one of the connecting surfaces of the sub-segments according to a preferred embodiment of the invention, in which the contacts are when the switch is engaged. Preferred positions of said recesses will be explained later in more detail.
  • the guide housing preferably has a further recess through which engages in the assembled state, an operating knob with which the switch is actuated.
  • the operating knob is a component of the end cap, in which the actuating button is mounted coaxially.
  • a flexible rubber seal is arranged between the actuating button and the switch, whereby the switch and the contacts are stored dust and moisture-proof.
  • the guide housing is releasably secured within the end cap, for which the guide housing preferably has an external thread and the end cap preferably has a corresponding internal thread, so that the guide housing can be screwed into the end cap ,
  • the guide housing could also be connected by means of a plug-in, latching or bayonet connection with the end cap. This provides a stable and easy-to-install way to safely store the switch within an end cap. Noteworthy here is the small number of components used, since in addition to the end cap, the two-part guide housing and the switch no other components must be used to realize a functional Endkappenschalter. This not only reduces the material costs, but also the assembly costs.
  • the contacts which protrude as leaf springs from the guide housing, must be connected to current-carrying parts of the flashlight.
  • two different possibilities are provided for this purpose, which differ essentially by the configuration of the first contact element, without the present invention being limited thereto.
  • the second contact element engages through a recess of the guide housing and forms on the end face in the assembled state an electrical contact to a pole of the battery or the accumulator.
  • a coil spring on the other hand, designed as a bent leaf spring contact can be tightly connected to the pole.
  • the leaf spring can also be fixed via a small screw or other fastening means.
  • the first contact element engages through a recess of the guide housing and forms an electrical contact with the flashlight housing in the assembled state.
  • the recess is formed on the end face of the guide housing, wherein the first contact is designed as a bent leaf spring and engages through the recess and the protruding part of the contact, the cylindrical shell of the guide housing at least partially surrounds the end, so that a contact closure to the flashlight housing, for this purpose preferably has a sockeiförmigen projection as a contact surface and electrical contact surface.
  • the end cap can be screwed onto the flashlight housing, the pressure with which the first contact element is pressed against the sockeiförmigen projection can be chosen arbitrarily, so that there is an extremely solid and secure contact is created.
  • this embodiment provides the advantage that the current does not flow via the end cap but directly onto the tab. barrel lamp housing is performed, which compared to conventional flashlights a contact surface, namely from the end cap on the flashlight housing, is saved.
  • the first contact element engages through a recess of the guide housing and forms an electrical contact with the end cap in the assembled state.
  • the recess is formed on the lateral surface of the guide housing, wherein the first contact engages through this recess and the protruding from the recess end of the contact on a collar-shaped bearing surface which projects at least partially radially from the outer surface of the guide housing, so that in the assembled state Contact closure to the end cap is in which the guide housing is releasably fixed.
  • the support surface may be formed as an annular extension of the end face of the guide housing.
  • the first contact element is clamped between a support surface of the guide housing and the end cap, so that when screwing the guide housing into the end cap secure contact is created by a high pressure.
  • the current is passed over the end cap in this embodiment, whereby a further contact surface between the end cap and flashlight housing is accepted, however, the first contact in this embodiment is stored safely from dust and dirt, so that a battery change especially in dusty and dirty Low-risk environments involve contaminating the contact surface, which may interfere with electrical contact.
  • the switch has a simple plastic housing from which protrudes in addition to the contact elements and an actuator.
  • the actuating element is axially movable and / or frontally has an electrically conductive contact plate which is connectable to both contact elements simultaneously.
  • a contact element may be formed within the housing as a bent leaf spring, which is spaced in the relaxed state of the other contact element, wherein both contact elements are connected by the actuating element against the force of the leaf spring.
  • the actuating element is a pressure or rotary knob which is axially movable against the force of a spiral spring. As a result, the actuating element is kept at a distance from the contacts in the relaxed state, so that unintentional switching on or off of the flashlight is prevented.
  • locking elements are provided on the confirmation element according to a further advantageous embodiment of the invention, so that a tactile function or optionally a permanent switching function is adjustable. This not only increases the handling of the flashlight, but also the functionality.
  • Fig. 3a, b one embodiment of a switch
  • Fig. 4a, b the operating principle of a switch.
  • the switch 1 as it is preferably used in the circuit arrangement according to the invention or in the flashlight according to the invention, has a housing 2 and an axially displaceable actuating element 3 designed as a latch or push button. Furthermore, a first contact element 4 and a second contact element 4 are provided Contact element 5 is provided, wherein both contact elements 4, 5 may be formed as bent leaf springs (see Fig .. 1b). Such a switch 1 is integrated with the contact elements 4, 5 projecting out of the housing 2 into an end cap 6 (cf., Fig. 1f), which can be screwed onto a flashlight housing 7 at the end (see Fig. 1g). Within the flashlight housing 7 is a battery 8 with the poles 9, 10, wherein the pole 10 is connected to the second contact element 5.
