Description

The proposed utility model generally relates to a design solution for the implementation of electrical and mechanical connection of devices and, in particular, to a design solution of an adapter with a magnetic mount for connecting electronic devices.

Most often, magnetic mounts are used in chargers and network adapters that transfer energy from an energy source to a consumer. Some of them additionally have data lines.

The first chargers appeared with the advent of the first energy accumulators at the beginning of the 19th century. Currently, the sector of chargers is steadily expanding, and at the same time, the variety of their mounts when connected.

There are many classifications of chargers. All of them are based on various parameters and properties of devices. By the method of connecting such devices, the following types of connections can be distinguished:

1. Contact with detachable connection. They are the most common chargers. The principle of operation of such devices is based on the mechanical detachable connection of the electrical contacts of the charging and charging devices.

The advantages of such chargers are the ability to quickly charge due to the possibility of transmitting a large level of charging current, as well as proven manufacturing techniques and prevalence. The disadvantages include less convenient connection than contactless, as well as the limited life of the connectors due to the mechanical wear of their parts during operation.

2. Contactless chargers. The principle of electromagnetic induction is the basis for the work of non-contact transmission of electrical energy. When an alternating current is applied to a conductive coil in a charger in an environment, an electromagnetic field arises that creates an electric current in the coil of the charging device.

The advantages of these chargers include convenience and speed of connection, as well as the absence of mechanical detachable connections. The disadvantages include a low efficiency and a longer charge time compared to contact chargers due to lower current levels with non-contact energy transfer.

3. Contact chargers with magnetic fastening. The principle of operation of such devices is based on the fact that the electrical connection of the contacts of the charging and charging devices is fixed using magnetic fastening.

These chargers combine the advantages of the first two types of chargers described above: high speed charging contact devices with detachable connection and at the same time the convenience of mechanical fastening of contactless devices.

The first type of battery charger is the Sony UCH32C quick charge device from Sony, available on the Internet at https://store.sony.ru/product/ustroystvo-dlva-bistroy-zaryadki-sony-uch32c-316483/. This charger consists of an adapter, which is an electric current converter, as well as a cable with a micro USB connector.

The disadvantages of this charger include the inconvenience of the connection and the reduced resource of the connectors, characteristic of the first of the types of connections described above. The miniaturization of the used connectors makes it difficult to observe the polarity when connecting the charging and charging devices, i.e. correct jointing and increases the likelihood of damage to connectors during operation.

An example of a second type of charger is Apple's mophie wireless charging stand, available online at https://www.apple.com/shop/product/HN7V2Z/A. This wireless device consists of a power cable and a stand, on the surface of which is located a rechargeable device.

The disadvantages of this stand include the extended charge time inherent in this type of device, as well as the lack of fixation of the charging device on the stand.

Chargers of the second type also include Apple Watch Apple charger, described on the Internet at https://www.apple.com/shop/product/MX2H2ZM/A. This charger is a magnetic module with wireless charging and a Type-C USB cable.

The main disadvantage of this charger, as in the previous example, is the increased charge time of the charged device.

The third type of charger includes the Baseus Mini Magnetic USB Toure-S CATCX-OG magnetic adapter, available on the Internet at https://www.ozon.ru/context/detail/id/155671337. This magnetic adapter is an adapter between a standard USB cable and a rechargeable device and has a detachable magnetic connection. The magnetic adapter consists of two parts. The standard USB cable is inserted into the first part of the adapter, and the second part of the adapter is a connector and inserted into a rechargeable device. The first and second parts are attached to each other due to the force created by the magnetic field while providing electrical contact. To protect against short circuits of power circuits if the connection is incorrect, a symmetrical arrangement of contacts is used when connecting two parts of the adapter.

The disadvantages of this magnetic adapter include the fact that the possibility of connecting with the wrong polarity is not prevented - only protection against short circuit if connected incorrectly is provided. Another disadvantage is that the connector remains in the protruding part of the charging device, which creates an additional inconvenience and risk of breakage of the connector. A disadvantage is also the weak magnetic connection due to the use of magnets on only one side of the magnetic connection. This magnetic adapter, like the previous ones, is designed to connect only one device. At the same time, in a number of tasks for data or energy transfer it is required to connect several connected devices to one device at once - for example, a spare battery is often included in the package of products, which is convenient to charge simultaneously with the main battery.

Chargers of the third type also include a Sony USB magnetic cable charger, available on the Internet at https://www.joom.com/en/products/1509886962208587347-222-1-26193-2212129908. This magnetic charger, like the previous adapter, is an adapter between a standard USB cable and a rechargeable device. This adapter has a magnet protected by a metal plate. The polarity of the connection is ensured by the different shape of the protrusions around the contacts.

The disadvantages of this charger is that the polarity of the connection of the charger is ensured only due to the presence of protrusions of the appropriate shape around the contacts, which must be reached when the adapter is connected, and not due to the attraction to the corresponding pole of the magnet, as well as a weak magnetic connection due to the use magnet on only one side of the magnetic connection.

The third type of charger also includes Apple MagSafe 60W Apple Power Adapter, available online at https://www.apple.com/shop/product/MC461LL/A/apple-60w-magsafe-power-adapter -for-macbook-and-13-inch-macbook-pro. The Apple MagSafe power adapter device, protected by US patent No. 7311526 “Magnetic connector for an electronic device” dated January 25, 2007, owned by Apple Inc (USA), is the closest in technical essence and the achieved result and is taken as the closest analogue (prototype).

The prototype device comprises a housing, magnets mounted by different poles in the direction of the connected devices, a spring contact block, a connector, and, by the totality of features, is closest to the totality of essential features of the utility model.

The disadvantage of the prototype device is that the device design is designed to connect only one device, and also does not allow the use of common standard cable types of the required length and configuration of the connectors.

In all of the chargers discussed above, magnets or metal plates are mounted on the external surfaces of the devices. A feature of magnets is their fragility, which is why they are prone to chipping during mechanical shocks. In this regard, they are often protected by metal plates. It is possible to give a more aesthetic appearance and eliminate the likelihood of chipping magnets by hiding the magnetic elements inside the case behind a wall of small thickness. To ensure sufficient gravity, it is necessary to use magnets on both sides of the magnetic joint.

The technical problem to which the claimed utility model is directed is the development of a magnetic adapter that allows expanding the functionality of a device with a magnetic mount by connecting two devices at the same time and ensuring their ease of mounting, as well as ensuring reliability and safety when connecting them.

The technical result from the use of the proposed utility model is the ability to connect two devices simultaneously to the opposite poles of each magnet of the magnetic adapter and increase the reliability of holding the connecting elements in a closed state by increasing the attractive force in the magnetic mount. An additional technical result is the safety and ease of attachment of connected devices when transmitting information and energy when charging or power supply.

The specified technical result is achieved due to the fact that the adapter includes a second spring contact block, the first and second spring contact blocks being located on opposite sides of the adapter housing, allowing two devices to be connected at the same time, the guiding protrusions on the spring contact side, allowing the adapter to be mechanically centered in relation to the connected devices and to prevent incorrect connection, two magnets mounted at different poles coaxially with the corresponding magnets in the connected devices, and the connection of the second connected device leads to an additional increase in the attractive force in the magnetic mount for both connected devices.

The essence of the utility model is illustrated by drawings:

- FIG. 1 is a general view of a structural embodiment of a magnetic adapter;

- FIG. 2 and FIG. 3 - examples of connecting a magnetic adapter with two devices at the same time.

The drawings show:

1 - housing adapter magnetic;

2 - connector;

3 - spring contact block;

4 - guiding protrusions;

5 - magnets in the case of the magnetic adapter;

6 - magnets in the first connected device;

7 - magnets in the second connected device.

The magnetic adapter at the end of the housing 1 or in another convenient place contains a connector 2 of a standard common type, for example, microUSB or USB type C connectors, which allows you to use common standard cables to connect it, or, if necessary, an integrated cable instead of a connector. On the sides of the housing 1 of the magnetic adapter are located opposite each other the first and second blocks of spring contacts 3, which allows you to connect two devices to the magnetic adapter at the same time. Correctness and faultlessness of the connection is provided by two magnets 5, which are installed at different poles coaxially with the corresponding magnets 6 and 7 in the connected devices, as indicated by the direction of the arrows in FIG. 2 and FIG. 3. In FIG. 2 and FIG. It can be seen that magnets 5, 6, 7 form a pair of magnetic groups. On the side of the first and second spring contact blocks, guide protrusions 4 are made, which allow to mechanically center the magnetic adapter with respect to the connected devices and prevent incorrect connection.

The simultaneous connection of two devices is ensured by installing the first and second blocks of spring contacts 3 on both sides of the magnetic adapter and two magnets 5 installed by different poles in the direction of the connected devices inside the case.

The magnitude of the force of mutual attraction of the magnets is determined by the size of the magnets and is selected based on ensuring the reliability of fastening and comfortable effort to disconnect the magnets when disconnecting the magnetic adapter. The installation of magnets both in the magnetic adapter and in the connected devices increases the strength of the magnetic field, which leads to an increase in the mutual attraction force of the magnetic adapter and two connected devices. In the considered design of the magnetic adapter, the attachment of the second connected device additionally leads to an increase in the attractive force due to the addition of magnets 7 (third magnet 7 to each magnetic group). This allows you to reduce the overall dimensions of the magnets used and the magnetic adapter as a whole and allows you to place the magnets behind the thin wall of the magnetic adapter housing to exclude the possibility of mechanical damage (spalling) of the magnets, as well as give a more aesthetic appearance to the magnetic adapter and connected devices.

In FIG. 2 and FIG. Figure 3 shows an example of connecting a magnetic adapter with two devices at the same time. The magnets 6 of the first connected device increase the attractive force of the magnets 5 of the magnetic adapter itself when connecting the second connected device from the opposite side, because magnets 5, 6, 7 are connected in series in each magnetic group, which increases the attractive force for the second connected device. Thus, two devices can be connected at the same time due to the use of magnetic mounts in the form of a pair of magnetic groups mounted by different poles in alignment with the corresponding magnets in the connected devices.

Also, the difference from the prototype lies in the secretive installation of magnetic fasteners, which gives a more aesthetic appearance and protects the magnets from mechanical damage (chipping) during operation, as well as providing the ability to connect two devices at the same time with the exception of the probability of incorrect connection. The utility model also provides the ability to use common standard cables.

Thus, the proposed utility model, in which the magnetic adapter contains two spring contact blocks, the first and second spring contact blocks are located on opposite sides of the adapter housing, providing the connection of two devices at the same time, the guiding protrusions on the side of the spring contacts, allowing the adapter to be mechanically centered along with respect to connected devices and to prevent incorrect connection, two magnets mounted at different poles coaxially with the corresponding magnets in connected devices are technically feasible and can solve the problem, expand the variety of devices with magnetic fastening and expand their functionality by increasing the number of simultaneously connected devices with a simultaneous increase in the strength of the magnetic compound.
