Definitions
- the invention relates to a charging cradle for at least one electrical device, which has a fixation of the electrical device and a movably mounted, electrical contact unit matching the electrical device contact unit and which automatically makes the electrical contact after the electrical device has been inserted.
- Patent application EP 22 28 263 A1 shows an invention in which an electrical device is accommodated, but the electrical connection must also be made manually.
- Patent application DE10 2009 017 265 A1 shows a device holder in which, when the electrical device is inserted, the electrical contact is also established via fixed contacts.
- US Pat. No. 7,477,039 B2 describes a charging cradle in which the positioning of the mobile electrical device in the charging cradle is described using magnets, the magnets and electrical contact unit of the charging cradle not being designed to be movable.
- a rigid connection between the electrical contact unit of the charging cradle and the electrical device contact unit also leads to the transmission of vibrations, for example in a vehicle, which affect other electronic devices Transfer assemblies in the device and, in the worst case, lead to mechanical damage.
- the object of this present invention is to design a charging cradle in such a way that after the electrical device to be charged and fixed has been inserted into the charging cradle, the electrical contact between the contact unit and the device contact unit is established automatically, and in this position the electrical contact unit of the charging cradle is removed from it is vibration-decoupled and the device is mechanically well fixed, for example in the case of strong vibrations, and thus permanent electrical contact is guaranteed.
- a movably mounted contact unit assembly (9, 9 ') installed in the charging holder housing (14) enables the insertion and fixing of the electrical device (20) by at least one Device terminal (6) facilitates and that an electrical connection is made independently, i.e.
- the electrical device contact unit is connected to an electrical device contact adapter, for example via the standard micro-USB connector, and this electrical device contact adapter in turn via open coupling contacts, for example Spring contacts, matching the electrical contact unit of the charging cradle, and after inserting the electrical device and reaching the device end position in the charging cradle between the electrical contact unit of the charging cradle, which is magnetic and / or at least ferromagnetic and the electrical device contact adapter, which is magnetic, a structurally provided air gap is automatically bridged by the magnetic force of attraction, the electrical contact unit of the charging cradle including cable in this way in at least one receptacle with up to six degrees of freedom is kept movable, that no greater or additional mechanical force than the available magnetic force of attraction is required to establish and maintain the mechanical and electrical connection between the electrical contact unit of the charging holder and the electrical device contact adapter and at least one mechanical device holder of the charging holder is the device holds in position.
- an electrical device contact adapter for example via the standard micro-USB connector
- the mechanical connection to the opposite electrical device contact unit of the previously used electrical device takes place automatically by means of an electrical device contact adapter, which is magnetic and has a sufficiently strong magnetic force of attraction to enable the mechanical and electrical Establish and maintain a connection between the charging cradle and the device.
- Magnetic USB cables with an electrical contact unit with open coupling contacts and a matching electrical device contact adapter with standard connections available on the market, such as micro-USB, are already commercially available and are particularly suitable for use with small-scale charging cradles.
- the electrical device contact adapter can be omitted.
- the charging cradle for the thermal imaging camera Reveal with micro-USB connection a commercially available magnetic USB cable with an electrical contact unit and a suitable magnetic micro-USB device contact adapter is used, with the electrical contact unit provided with a cable in a mounting block of the charging cradle is fixed. This mounting block can be individually adapted to use cables from different manufacturers.
- One contact unit per charging cradle forms the contact unit assembly with a mounting block, in one version with two bridge arms, two lateral receptacles and the device receiving surface with contact opening.
- This contact unit assembly is fixed in the charging cradle housing via the lateral receptacle and a charging cradle cover.
- the mounting block with contact unit is held movably by means of two bridge arms, for example, in two lateral receptacles, each with a groove.
- the grooves are ideally dimensioned in such a way that the bridge arms no longer have any contact with the charging cradle after the electrical connection has been made via the side mounts and so vibrations cannot be transmitted and mechanical damage to the electrical connection between the device and the charging cradle due to external forces is avoided.
- Vibration dampening of the electrical contact unit can also be implemented by a resilient design of the bridge arm, which is then, for example, fixed to the side mounts without play and the mobility of the contact unit is achieved by the bridge arm itself.
- the assembly block of the electrical contact unit can also be designed in the form of a geometric body, for example as a cone, cylinder, spherical, cone or pyramid and in a geometrically matched receptacle, optionally also as a hollow body, directly under the contact passage opening in the Device support surface positioned, movable with up to six degrees of freedom.
- the return of the universal, electrical contact unit into the receptacle of the charging cradle can also be supported by an elastic return component, for example by an elastic charging and data cable, fixed via a strain relief in the charging cradle housing.
- At least one spring component is required to make a contact unit assembly movable, which simplifies the insertion, but also the removal of the electrical device from the charging cradle, especially if at least one device holder fixes the device in the charging holder.
