Definitions

  • the present invention relates to an electrical device with at least one electromechanical contacting means for an electromechanical contacting means counterpart, such as a socket for a plug, and at least one magnetic contacting means for a magnetic contacting means counterpart, such as a magnetic contact socket for a magnetic contact plug.
  • Electromechanical and magneto-electric or magnetic contacting means are used to establish an electrical contact, for example for the purpose of transmitting data or for power supply, between the electrical lines of a cable and the corresponding lines within an electrical or electronic device, hereinafter referred to as electrical device Magnetic contacting means or connector systems are known.
  • the former comprise a male part, with contact pins projecting beyond a reference surface, and a compatibly shaped female part, with appropriately located and dimensioned inwardly facing contact openings.
  • a female connector permanently installed in a housing is usually referred to as a socket and a permanently installed male connector is referred to as a built-in plug.
  • a male connector attached to one end of a cable is called a plug.
  • the contact pins and contact openings of the plug or socket are connected to the corresponding leads of the cable or electrical device with which they belong.
  • plugs that are frictionally inserted into the contact openings of the socket are already able to absorb a certain mechanical load, both axially, i.e. in the direction of the longitudinal axis of the plug connection or connection direction, and laterally, i.e. transversely to the longitudinal axis, but on the one hand this is usually not high and on the other hand, there is a risk of deformation or breakage of the mostly thin contact pins.
  • a mechanically more stable connection between plug and socket is achieved in that additional mechanical connecting elements are provided to absorb the load.
  • plugs often include a skirt surrounding the contact pins, which can engage in a complementary opening in the socket surrounding the contact openings in a closed manner. The skirt can also be part of the bushing. In addition to its mechanical connection function, it often serves as a ground contact.
  • Electromechanical contacting means have the advantage, depending on the design, of being able to absorb quite large mechanical forces without the electrical connection(s) being interrupted.
  • a disadvantage is that the action of large mechanical forces, especially if they act laterally, can result in damage in the form of plastic deformation or even breakage of the plug and/or socket or at least individual contacts.
  • both the contact pins and the contact openings wear out over time, ie they wear out with an increasing number of plugging and unplugging processes, so that the frictional connection gets weaker until at some point both the mechanical hold and the electrical contact are no longer ensured (loose contact formation).
  • magnétique contacting means These are plugs and matching sockets in which the mechanical cohesion is not achieved, or not exclusively, by frictional engagement between mechanical connecting elements, but rather by the mutual magnetic attraction of magnetic elements in the plug and socket.
  • the magnetic elements is at least one magnet, usually a permanent magnet, which can be arranged in the plug or socket.
  • the magnetic element serving as a counterpart in the socket or plug can also be a magnet oriented accordingly to achieve an attractive force, such as a permanent magnet or an electromagnet, or a piece of magnetizable material is used, in which case the correct position is not required orientation must be taken into account.
  • These magnetic elements are usually located behind the reference surface of the plug and socket so that when mated they are close together so that they can exert a strong magnetic attraction on each other.
  • the direction of magnetization of the magnetic elements is aligned perpendicularly to the reference surface.
  • the electrical contacts are pressed together by the magnetic force of attraction between plug and socket, thus ensuring adequate contact.
  • magnetic contacting means ie magnetic plugs and sockets
  • magnetic plugs and sockets are their greater complexity and the slightly higher weight and volume compared to an electromechanical plug with the same number of electrical contacts.
  • the terms "mechanical” and “electromechanical” or “magnetic” and “magneto-electrical” contacting means or magnetic contacting means are used synonymously below. Also, unless otherwise stated, no distinction should be made between a socket and a built-in plug. In the following, the element located in the electrical device is referred to as a socket and the element located at the cable end of the cable to be connected is referred to as a plug.
  • the object on which the present invention is based is therefore to overcome the problems described above in a compact electrical device and to provide an additional contacting option which does not require its own protective cover and, ideally, can even be retrofitted.
  • the electrical device has at least one electromechanical contacting means in the form of a socket or a built-in plug, which can be closed by the cover cap according to the invention, which is captively connected to the housing of the electrical device.
  • a magnetic contacting means in the form of a magnetic plug or a magnetic socket is integrated into the covering cap. This is preferably arranged in the upper side of the covering cap, but in any case in such a way that even when the covering cap is in the closed state, ie in the state in which it closes the electromechanical contacting means complementary magnetic contact means counterpart, ie about a magnetic connector, can be connected.
  • Both the electromechanical and the magnetic contacting means represent an interface of the electrical device, via which it can be supplied with power or data can be transmitted.
  • the magnetic contacting means can represent its own such interface for the power supply of the electrical device or for data transmission to other electrical devices or a communication network, either independently of the electromechanical contacting means covered by the covering cap. In this case, it would be conceivable to use both interfaces or contacting means at the same time by opening the cap so that the electromechanical contacting means underneath is accessible. With a corresponding structural design of the cap and arrangement of the magnetic contact means integrated therein, which are readily apparent to a person skilled in the art, an electromechanical contacting means counterpart and a magnetic contacting means counterpart can be connected to the respective contacting means of the electrical device at the same time.
  • a counterpart to the electromechanical contacting means that can be closed by the cap on the underside, i.e. the side facing the housing, of the covering cap, which is positioned in such a way that it is coupled to the electromechanical contacting means in the closed state of the covering cap .
  • the electrical contacts of the counterpart on the underside of the cap and the electrical contacts of the magnetic contacting means which is preferably arranged on the top of the cap, i.e. the side opposite the underside of the cap, are partially or all electrically connected, so that when a counterpart is connected to the magnetic contacting means in the closed state of the cap effectively a connection between this counterpart and the closed by the cap electromechanical interface is made.
  • the design of the magnetic contact means is fundamentally arbitrary within the scope of the present invention. If basic compatibility with the electromechanical contacting means is desired, it is only necessary to ensure that a magnetic contact means has electrical contacts with a sufficient number for the desired purpose (data transmission and/or voltage supply) and with sufficient cross-sectional dimensioning for the currents flowing. If the interface is to be used for the transmission of high-frequency signals, especially with higher currents, aspects of electromagnetic compatibility must also be taken into account.
  • the electrical device can be any electrical or electronic device that can be wired or mobile, i.e. can operate completely without a cable for power supply or data transmission.
  • it can include any other assemblies and components, such as a power pack, transmitter and receiver units for wireless data reception, a data display, audio input and / or output means, switches, input means such as a Keyboard, a keypad and/or a touch-sensitive display, data collection means such as temperature, pressure, acceleration or radiation sensors or cameras, and one or more central control units for linking and functional coordination of these peripheral components.
  • the electromechanical and magnetic contacting means present according to the invention are part of interfaces via which the electrical device communicates with other electrical devices or a data network and/or is supplied with an operating voltage.
  • a dual function of data communication and supply of operating voltage is implemented, for example, by a USB interface.
  • the electrical device is particularly preferably a mobile electrical device such as a pocket lamp or a mobile data processing and/or communication device such as a laptop PC, a tablet or a smartphone.
  • the invention provides a space-saving connection option for both electromechanical and magnetic contacting means and improves the versatility and usability of the device. Either two interfaces essentially become one within the volume single interface of the prior art, or the user will still be able to connect an interface to cables having an electromechanical or magnetic contacting means counterpart if desired or available. As a result, the advantages of both types of contacting means are combined in one interface without significantly increasing the installation space for the interface.
  • a fastening option for a cover cap according to the invention on the electrical device, if it is not already present, and then fastening it to it.
  • an opening for inserting a locking pin of the cover cap can be drilled in the area of the electromechanical contacting means to be closed and the locking pin can then be inserted and the cap can be captively attached to the housing, creating an electrical device according to the invention.
  • the magnetic contacting means which according to the invention is integrated into the covering cap of an electromechanical contacting means, preferably has an approximately annular contact which serves in particular as a ground contact. Furthermore, there is at least one contact pin surrounded by the annular contact, which serves in particular as a power contact. In further preferred embodiments, there can also be more than one contact pin, for example two, three, four or six contact pins. These can be loaded with a preload force via a common spring, which ensures sufficient electrical contact when plugged in. Alternatively, subgroups of contact pins can also have their own preload springs. In extreme cases, each contact pin has its own preload spring. Such a configuration is the most complex to manufacture, but promises the highest contacting reliability and can also cope with slightly lower manufacturing tolerances, since these are compensated to a certain extent by the spring deflection that is automatically adjusted individually for each contact pin.
  • the fastening means which connects the cover cap to the housing of the electrical device in a captive manner, consists of a pin protruding from the underside, which penetrates through an opening in the housing that is shaped complementarily to a cross section of the pin.
  • the pin has a thickened section at a section located inside the housing, ie a section with a larger cross-section than the intermediate part of the pin. This can be a spherical thickening or a conical thickening.
  • the pin In the closed state of the covering cap, the pin is pushed into the opening so far that the area located near the underside of the covering cap is in the housing opening. To open the cover cap, it is lifted, whereby the pin is pulled further out of the opening. This is as far as possible until the thickened section of the pin prevents further withdrawal.
  • the length of the pin or the distance between the underside of the covering cap and the cross-sectional enlargement is chosen to be sufficient here in order to be able to pivot the covering cap out of the region of the electromechanical contacting means located underneath.
  • the electromechanical contacting means is located within an indentation or recess let into the housing wall, for example rectangular or oval in shape, which corresponds to the shape and size of the covering cap.
  • the indentation thus forms a seat for the cover cap, which, with a suitable design in terms of material and geometry, for which many suitable options are apparent to the person skilled in the art, effectively protects the contacting means against the ingress of smaller solid foreign bodies or even liquids, particularly preferably dust and/or or splash-proof or watertight in the sense of the IP classification known to those skilled in the art.
  • the length of the pin is preferably somewhat greater, at least about 10% greater than the depth of the depression. Most preferably, the pin is 10-30% longer than this depth.
  • the pin can be made of the same material as the cap.
  • the material of the pin preferably has a certain elasticity, for example soft plastic or solid rubber, so that the cover cap is flexible when it is open.
  • An alternative means of attachment of the overcap is a pair of aligned pins projecting from the top and bottom connecting opposite sidewalls which engage notches on opposite sides of the recess or housing recess which forms a seat for the overcap.
  • the notches run to near but not quite to the top of the recess so that each of the pins cannot leave its notch and captive attachment is achieved.
  • the cap can be lifted to open in a straight line movement, moving the pins up in the notches until they abut the top of them. With a pivoting movement about the axis defined by the pins, the cap can then be brought out of the area above the electromechanical contacting means, so that it is possible to insert a contacting counterpart.
  • the electromechanical interface together with the covering cap and the recess forming a seat for this, is particularly preferably located within a further, larger depression or recess which has a beveled side surface, so that the covering cap is easier to grip when it is closed.
  • the covering cap according to the invention has a projection projecting beyond its side surfaces or board that improves grip to open or close the top cap.
  • This can preferably be arranged on a side surface of the covering cap that is different from the underside and the top.
  • Two or more projections are particularly preferably arranged in pairs on opposite side surfaces of the covering cap, with the projections of a pair being aligned with one another.
  • the electromechanical interface is also preferably a socket for a jack plug, barrel plug, Lightning plug, USB-C plug or micro-USB plug.
  • FIG. 1 illustrates a preferred embodiment of a covering cap for an electromechanical contacting means in the form of a micro-USB socket in an electrical device an integrated magnetic contacting means. Since the electrical device in which it is used is completely arbitrary, it or its housing is only shown partially in the figures.
  • the sub-figures figure 1 show in an exaggerated perspective view the interaction of the electrical device according to the invention with an electromechanical contact counterpart in the form of a micro-USB plug.
  • Part A shows the state before the micro-USB plug 4 is plugged into the socket 20 .
  • the cover cap 3 is lifted out of its seat in the recess 27 and rotated 180 degrees about the axis formed by the captive pin 34 of the fastener 23, so that there is sufficient space for the housing 41 of the plug 4 to the coupling part 46 of the plug Insert 4 into the coupling opening 24 of the socket 20 and thus be able to connect the plug 4 and socket 20.
  • the state thus reached is illustrated in subfigure B.
  • the indentation 27 lies within a larger indentation which has two opposite beveled sides 25, whereby the cover cap, when it is in the closed state in the indentation 27 and thus closes the coupling opening 24 of the socket 20 in a dust- and/or water-tight manner, is easier to grasp by hand is.
  • the covering cap 3 also has two projections 31 as gripping aids, which are arranged flush with one another on opposite side surfaces of the covering cap 3 .
  • a magnetic or, for short, magnet contacting means 38 is integrated into the covering cap 3 on its On the top and on the opposite, housing-facing underside, next to the pin 34, a micro-USB coupling part 36.
  • a micro-USB Coupling part 36 is inserted into the coupling opening 24 . Since the electrical contacts of the coupling part 36 and those of the magnetic contacting means 38 are connected via electrical lines in the cover cap 3, a connection is effectively created between the socket 20 and the magnetic contacting means 38, so that the socket 20 can be contacted with a corresponding magnetic contacting means counterpart.
  • Subfigure A again shows the state before connection.
  • the cover cap 3 has not yet been inserted into its seat in the depression 27, but is already correctly aligned for this purpose.
  • the cover cap 3 can be pushed into the depression 27 and at the same time the micro-USB coupling part 36 protruding from the underside of the cover cap can be pushed into the coupling opening 24.
  • the coupling counterpart 52 of the magnetic contact plug 5 can then be connected to the magnetic contacting means 38 .
  • the pin 34 of the cap attachment 23 passes through the opening 26, which is located within the recess 20 in the housing 2 and has a clear width which is slightly larger than the diameter of the pin 34.
  • At the lower end of the pin 34 is, as in Figure 2B to see a conical thickened portion 341, which has a larger diameter than the opening 26, and thus forms the captive of the pin.
