Definitions

  • the present invention relates to a charger for an electrical device, in particular a mobile radio terminal.
  • Chargers which comprise a receiving unit by which the electrical device to be charged is held.
  • the electrical device which has a plug-in receptacle, is inserted into a receptacle unit in which it can slide into a position in which electrical contact can be made with the charger.
  • a plug receptacle is understood to mean, for example, a socket which is complementary to, for example, a plug which is located on the charger.
  • the alignment of the plug or its contact pins defines a target insertion axis under which the electrical device is to be inserted into the receiving unit.
  • the receiving unit on the charger serves to prevent the electrical device from being tilted in and to fix it during the charging process, since otherwise damage to the plug receptacle of the electrical device or the plug element of the recording unit can occur.
  • the recording unit can be designed differently:
  • the latter is introduced into a receiving slot, the internal dimensions of which roughly correspond to the external dimensions of the mobile radio terminal.
  • a tilted insertion is still possible depending on the shape of the electrical device and the receiving unit.
  • the plug receptacle of the electrical device or the plug element By inserting the electrical device into the receptacle unit tilted relative to the insertion axis, the plug receptacle of the electrical device or the plug element, which is located on the charger and by means of which the electrical contact is established, can be damaged. In addition, no electrical contact can be made even when inserting with only a small tilt relative to the target insertion axis.
  • the electrical device is guided by means of the receiving unit or a rail-like guide within the receiving unit.
  • the dimensions of the recording unit are largely determined by the device to be charged. In order to fix the device correctly, the recording unit must have a sufficient length. Of course, this affects the overall size and shape of the charger.
  • the manufacturer must therefore design a largely individual charger for each electrical device, since the recording unit itself and the overall design of the charger are designed differently based on different electrical devices; this results in higher costs.
  • Another significant disadvantage is that it is sufficiently difficult to fix the electrical device, for example in the case of oval or even round shapes, such as are provided, for example, for 3rd generation mobile radio terminals. It is therefore an object of the present invention to provide a charger which allows electrical contact to be made between the electrical device and the charger more reliably than in the prior art, the risk of damage to the electrical device and / or the charger being reduced.
  • a plug element which makes the electrical contact between the electrical device and the charger, is mounted elastically.
  • the elastic mounting reduces the risk of damage to the electrical device and / or the charger when the electrical contact is made. Damage would occur if sufficiently large forces act between the plug element and the plug receptacle in a direction other than that required to establish the electrical contact.
  • the invention prevents the occurrence of these forces which are sufficiently large for damage by the elastic mounting. This is without pressure on the elastic bearing
  • Plug element in a rest position for example, the plug element in the form of the contact pins defines the target insertion axis for the electrical device in the receiving unit.
  • target insertion axis is used as just defined; the term “insertion axis” in the following describes the direction which is defined by the contact pins, for example, even if the plug element is not in its rest position. Ideally, the electrical device is inserted along this desired insertion axis, as a result of which contact can be established between the electrical device and the plug element in its rest position.
  • An embodiment variant of the invention provides for the occurrence of these forces to be prevented by a suitable insertion position and axis.
  • the plug element can be moved from a position in which insertion of the electrical device is possible to another position in which it can then be locked.
  • a position can be selected for the insertion of the electrical device which is favorable for the insertion.
  • the electrical device connected to the plug element can be brought into a position for locking the plug element and / or the electrical device.
  • the position for locking is selected, for example, according to the external circumstances, for example, to integrate the charger in a motor vehicle fitting.
  • Another embodiment variant of the invention consists in preventing the above-described forces by yielding the plug element.
  • the elastic bearing makes it possible to change the position of the plug element.
  • the elastic mounting is carried out in such a way that the plug element tends in one direction when pressure is applied in accordance with the tilting of the electrical device relative to the desired insertion axis, so that, for example, part of the plug element can now slide into the plug receptacle of the electrical device.
  • the avoidance of the plug element prevents damage to the plug element and / or the plug receptacle of the electrical device.
  • the elastic contact set consisting of the plug element and the elastic mounting enables insertion of the plug receptacle of the electrical device into a part of the plug element which is connected to the receptacle unit of the charger, which significantly reduces the risk of damage without the Recording unit is dimensioned unnecessarily large.
  • the elastic mounting also makes the charger more independent and it can be adapted to other requirements, for example the integration of a charger, for example for mobile radio terminals, in a motor vehicle.
  • a further development of the invention provides that the plug element alone or the plug element and the elastic mounting are made removable, whereby a largely modular construction of the charging station can be realized.
  • This has the advantage for production that, for example, the shape of the charger can remain largely unchanged by adapting the plug element to the respective electrical device. This makes production easier and less expensive because fewer individual parts can be manufactured in larger numbers.
  • the plug element is movable in at least two directions.
  • the elastic mounting is realized for example by a plate made of elastic material.
  • the plug element is integrated into this plate.
  • the plate is held at its edges, it is bendable in the inner region, as a result of which the orientation of the plug element and thus the insertion axis can be changed with respect to the desired insertion axis.
  • Rigidity of the plate is chosen, for example, according to the weight of the electrical device.
  • This realization of the elastic mounting offers the advantage of a simple production of a mounting which is movable through 360 ° in the plane perpendicular to the desired insertion axis.
  • the maximum permissible tilt of the plug element can be influenced, for example, by the rigidity of the plate.
  • this version of an elastic mounting can be held on the charger by a rail-like holder. This enables the plug element to be installed and removed easily.
  • a further embodiment variant of the elastic mounting can be a geometric body into which the connector element ment is integrated and which is supported by springs.
  • the springs can be located below, to the side of, or above the geometric body, for example.
  • a combined elastic bearing made of elastic plate and springs is also possible.
  • the body in which the plug element is incorporated can not only be designed in the form of a plate, but can also have any shape which is adapted to the requirements in the charger.
  • a shape adapted in this way a shape can be cited which optimally utilizes the space in the charger and / or enables a shift in the center of gravity.
  • the flexible storage would make space-saving charging of several electrical devices practically possible, since the bodies of the electrical devices can be arranged in a flower-like manner and thus do not block the space for the respective plug element.
  • FIGS. 3-6 as an exemplary embodiment, the contacting process for charging a mobile radio terminal and Figure 7 shows the insertion of an electrical device in a charger, in which the plug element assumes different positions for insertion and locking.
  • Figure 1 shows the contact set consisting of connector element STE and elastic mounting EL.
  • the elastic mounting EL is plate-shaped and the plug element STE is integrated in this plate.
  • the contact pins KS are located on the upper part of the plug element STE.
  • the contact set, consisting of the plug element STE and elastic mounting EL, is taken up by the charger LG.
  • a holder HA is used for receiving, which in this case is designed in an I-shape and by means of which the contact set can be brought into the desired position as on a rail.
  • the charger LG there is a recess AS for the upper part of the plug element STE.
  • the length of the leg HA2 of the holder HA corresponds to the thickness of the elastic bearing EL.
  • the leg HAI of the holder HA has a length that ensures that the contact set consisting of plug element STE and elastic bearing EL is securely held.
  • Such a device, as described in FIG. 1, represents a simple method for elastically mounting the plug element STE.
  • a modular structure can be easily realized by combining the contact set and the HA bracket.
  • the modular structure leads to cost savings in production, since parts of the charger can be manufactured identically for different electrical devices. On the one hand, this reduces the number of individual parts, on the other hand, parts are manufactured in larger numbers. Both effects reduce costs.
  • Figure 2 shows a further possibility for fastening the plug element to the charging station.
  • it is fixed via a plug contact.
  • the recess is pushed over the finger. It is locked, for example, by a spring-loaded nose on the FI finger.
  • the contact pins KS which are located on the upper part of the plug element STE, define a target insertion axis under which the electrical device should be inserted into the receiving unit of the charger.
  • FIG. 3 shows the situation in which an electrical device EG, which is tilted relative to the desired insertion axis SEA, is inserted into the receiving unit AE of the charger LG.
  • a new insertion axis EA is defined by the plug-in receptacle SA of the electrical device EG, for example in the form of a fitting groove which receives a contact pin KS.
  • the plug element STE is elastically mounted.
  • the elastic mounting EL is plate-shaped.
  • FIG. 4 shows the situation that an electrical device EG is inserted into the receiving unit AE of the charger LG in a tilted manner and electrical device EG and plug element STE are already touching.
  • the plug-in receptacle SA and the plug element STE do not meet correctly due to the insertion being tilted with respect to the target insertion axis SEA.
  • this force cannot lead to damage to the plug element STE, since this gives way due to the elastic mounting EL.
  • FIG. 5 shows the situation that an electrical device EG is inserted into the receiving unit AE with only a slight tilt relative to the desired insertion axis SEA.
  • the plug element STE yields due to a force that acts on the plug element due to the tilted insertion, such that the plug element aligns along the insertion axis and thus electrical contact between the plug kerelement STE and plug receptacle SA of the electrical device EG comes about.
  • Figure 6 shows the situation that the electrical device EG is in electrical contact with the plug element STE.
  • the plug element STE is now in its rest position, that is the position in which no lateral forces act on the plug element.
  • insertion axis EA and nominal insertion axis SEA are identical.
  • the elastic mounting EL prevents damage to the plug element STE when the insertion is tilted with respect to the desired insertion axis SEA.
  • this elastic mounting EL also causes an electrical contact to be made between the plug receptacle of the electrical device EG when the insertion is only slightly tilted with respect to the desired insertion axis SEA. Due to the restoring force of the elastic mounting, the plug element and the electrical device are brought back in the direction of the originally intended axis, the target insertion axis.
  • a maximum permissible tilt relative to the desired insertion axis SEA, at which an electrical contact can still be made, is defined, for example, by the dimensions of the contact pins AS of the plug element STE and the plug receptacle SA of the electrical device.
  • FIG. 6 shows the insertion of an electrical device EG into a charger, in which the plug element can assume different positions for insertion and locking.
  • the plug element STE points in a direction that enables the plug-in receptacle SA of the electrical device EG to be inserted easily.
  • the electrical device can be brought into a position due to the elastic mounting EL in which the electrical device or the plug element or both are locked. This locking can take place, for example, via a spring-mounted nose FN, which is attached to the charger.
  • Such an embodiment also enables simple insertion of the electrical device into the charging station, which reduces the risk of damage.
  • the invention is not limited to chargers for mobile radio terminals, but to be applied to any electrical devices.

Abstract

La présente invention concerne un dispositif de chargement pour appareils électriques. L'élément de connexion de ce dispositif de chargement qui permet d'établir le contact électrique est monté de manière élastique. Ceci permet, même lorsque l'appareil électrique bascule par rapport à l'axe d'introduction prévu, de n'endommager aucune partie de l'élément de connexion. On peut également choisir un axe d'introduction prévu avec lequel le risque d'endommagement est moindre, un blocage se produisant lorsque l'appareil se trouve dans une autre position dans laquelle il est par exemple mieux maintenu. A cette fin, l'élément de connexion servant à établir le contact électrique est monté de manière élastique, de façon que toutes les parties de l'élément de connexion soient mobiles par rapport à l'axe d'introduction prévu. Cette invention peut notamment s'appliquer aux dispositifs de chargement pour terminaux de téléphonie mobile.
