Definitions

  • the present invention relates to a flashlight with a cylindrical battery housing at one end of a current-conducting contact surface is formed, an end cap and a contact spring with contact points, which connects a pole of a battery housing mounted in the battery housing with the contact surface of the Breliteriegephaseuses.
  • Such a flashlight is for example in the DE 20 2007 009 202.4 described.
  • This has an end cap, in which a compression spring is arranged, which has a single spring wire with partially different winding diameter, wherein at least partially a plurality of windings is arranged radially adjacent to each other.
  • a compression spring is described which has two coaxially mounted partial regions which are each designed as helical springs. The partially radially adjacent end pieces of the contact springs form the contact points, wherein a contact point with the pole of a battery and the other contact point are connected to a contact surface of the battery case.
  • Another flashlight is off US 4,517,628 known, which forms a flashlight housing, at the rear end of a contact spring is arranged, the end has a radial portion which is formed as a leaf spring and is connectable to the conductive flashlight housing, including a slide switch is arranged.
  • JPS56-105201U a flashlight with a contact spring is described within the end cap, on the battery housing, a slide switch is arranged.
  • the contact points are arranged at opposite ends of the contact spring and the end cap is designed as a switch by the end cap and the battery case are connected by means of a thread that a contact closure by turning the end cap and by pressing the end caps using the thread play can be produced.
  • a flashlight which has a contact spring in its end cap, which has contact points at two opposite ends, which can be connected on the one hand to the pole of a battery and on the other hand to the contact surfaces of the battery case.
  • the contact spring is designed as a helical spring or a leaf spring, wherein other contact springs are conceivable.
  • the end cap has an external thread and the battery housing has a corresponding internal thread and that the contact spring end has at least one radial portion which engages in a recess of the end cap such that the portion in the assembled state with the contact surface of the Battery housing is connected.
  • the portion of the recess must protrude by a certain amount, so that the protruding portion can be pressed onto the contact surfaces of the battery case.
  • the contact surface may be arranged annularly or partially annularly on the end face of the battery housing.
  • the contact surface may be formed as a ring or semi-annular base within the battery case.
  • the recess is disposed between the threads of the end cap and a termination piece. At this point, the recess can be particularly easily introduced through a hole in the end cap.
  • the end cap has an internal thread and the battery housing has a corresponding external thread and that the contact spring has at least in a partial region such a large radius that this portion is connected in the installed state with the contact surface of the battery case
  • the contact spring is preferably a helical spring, which is preferably frusto-conical.
  • the frustoconical helical spring preferably has a partial region on the end with such a large radius that this partial region is connected in the installed state to the contact surface of the battery housing.
  • the tip end of the contact spring is connected to the battery and the extended end to the end cap or the contact surface, so that a circular line contact is formed.
  • This embodiment is particularly well designed as a switch, since the contact closure due to a line contact between the contact spring and battery case can be made by turning the end cap. It is further provided that the end cap can be screwed onto the battery case so far that the contact is just not closed so that a contact can be closed by utilizing the thread play, so this embodiment can also be designed as a push button.
  • the contact spring has a radial portion which is connected in one or two pieces with a clip, wherein the contact is made by rotating the end cap. Furthermore, according to a further embodiment, there is a gap between the partial area and the contact area in the installed state, so that the contact is closed by a pivoting movement of the clip.
  • the clip is arranged longitudinally axially on the battery housing.
  • This flashlight can be adjusted by turning the end cap so that the flashlight is closed by a slight pressing or pivoting of the clip a contact and the contact is interrupted by opposing pulling again. This even makes it possible to adjust the flashlight so that the contact is broken when the flashlight hangs on the clip in a pocket, such as a breast pocket, and the circuit is closed as soon as the flashlight is removed from the pocket.
  • FIG. 1 A and B is an exploded view of a flashlight 1 with a lamp head 2, a battery case 3, 4 batteries, an end cap 5 and designed as a helical spring contact spring 6 is shown.
  • the circuit is usually closed via the battery housing 3, to which this at least partially consists of a conductive material.
  • a conductive material preferably aluminum, which is used to cure the surface with Anodization can be treated.
  • the treated surface must be ground down for an electrical contact surface, for which purpose preferably the end face 7 of the battery housing is used, so that it can be used as a contact surface 8.
  • the contact spring 6 is provided, which has a radial portion 9 end, which can be inserted into a recess 10 so that it protrudes to a certain extent from the recess 10.
  • Fig. 2a to c is ever a detail view of an end cap 5 with a recess 10 and a contact spring 6 is shown, wherein Fig. 2c the end cap 5 with built-in contact spring 6 shows.
  • the end cap 5, together with the protruding radial section 9 must be screwed into the battery housing until the radial section 9 comes into contact with the contact surface 8.
  • an end cap with an external thread 11 and a battery housing 3 with a corresponding internal thread is suitable.
  • Fig. 3 shows an alternative embodiment in which a contact spring 6 is used, the end has an extended radius (arrow 30). As a result, a circular line contact is created, which can be connected to an annular contact surface 8 on the battery case.
  • an end cap 5 with an internal thread and a battery housing 3 with an external thread are preferably used.
  • Fig. 4a and b show the end cap 5 with a contact spring 6 in a detailed view, wherein the contact spring 6 end has an extended radius (arrow 30).
  • the radial portion 9 is connected to a clip 51, wherein between the portion 9 and the contact surface 8 in the installed state, a gap 52, so that the contact by a pivoting movement of the clip 51st closed ( Fig. 5a, b ).
  • the clip 51 is arranged longitudinally axially on the battery housing 3. This flashlight can be adjusted by turning the end cap 5, that the flashlight is closed by a slight pressing or pivoting of the clip 51 in the direction of arrow 53, a contact (see. Fig. 5b ) and the contact is interrupted again by opposing pulling.
  • Fig. 6a, b and c show further embodiments of a flashlight, where there the contact spring 6 is formed as a leaf spring 61.
  • the leaf spring 61 is integrally connected to a clip 51.
  • an electrical contact 62 is provided to a battery 4.
  • Another electrical contact 63 is arranged on the radial section 9, which merges into the clip 51 in one piece. The contact 63 can be closed by turning the end cap 5 or by a slight pressure, the end cap has to be screwed correspondingly far.
