The problem of lack of USB connectors
In our Prestigio Visconte Quad tablet, there is only one USB (microUSB) connector and it also charges from this connector. In this regard, there is an acute problem of lack of USB connectors and the inability to use peripheral devices while charging the tablet.
This topic was created to solve this actual problem.

Wiring Methods
  1. ScotchLok
    ScotchLok, ScotchLok, electrical connector with mortise contact.
    Attached Image

    This is for low voltage (network, telephones, LED lights, etc.).
    The point is simple - several wires are pushed into such a thing.
    After which it snaps into the pliers or any oppressive tool.
    Attached Image
    Attached Image

    They are especially loved by the installers of the SCS and networks, for simplicity, cheapness, water resistance, and the lack of the need to remove the insulation.
    Inside - a hydrophobic gel that protects against corrosion, moisture, oxidation, etc. And a plate with a cutting-clamping surface or two plates.
    Attached Image
    Attached Image

    What happens to the cable after installation?
    Knives cut the insulation, and firmly pressed to the wire.
    Attached Image
    There is also a version for two cables at once.
    By itself, they are disposable and maintenance-free. It is necessary to replace - a piece of cable is bitten off with them, and a new one is put.
    Cost: from 2-3 up to 5-7 rubles apiece.
    P.S. It is very convenient to use them - you do not need to remove the wire sheath, just put the wires into the adhesive tape and press it with pliers (the knives inside the adhesive tape cut the insulation and firmly pressed to the wire). There is one BUT - 4 wiring in the USB cable is very small in diameter and therefore sometimes they slip between the knives of scotch-locks (it is usually just enough to more firmly clamp the scotch-lok with pliers to cut the insulation of the wire deeper, but sometimes they have no luck and use the new scotch lok).
    At first I, until I got used to using them, spoiled about 10 scotch locks. Now I got it and it turns out the first time. Usually the problem is that you did not shake the scotch-lok, you just need to press the pliers harder. Therefore, take them more than you need, just in case.
    You can buy them at an electrical goods store, a radio goods store or in the construction market.

  2. Polyethylene terminal blocks
    Look like this
    Attached Image

    Sold in any hardware store, worth a penny.
    Inside here is a brass sleeve with two screws:
    Attached Image

    We push wires into it, we clamp with screws:
    Attached Image

    After that, we must isolate the sleeve with tape (because electricity passes through the sleeve itself). In this form, its size is almost halved. If the small size of the connection is not important to you, it is better to leave the sleeve inside the insulating box. Then the connection will look like this:
    Attached Image

    Each segment can be cut off. It would seem ideal. But there are drawbacks.
    - Do not clamp aluminum. The aluminum core has fluidity under constant pressure, and after a while the contact can easily disappear or deteriorate. What is fraught with - you know, heat and fire. Strictly speaking, ALL aluminum screw connections need to be tightened once a year.
    - Be careful with clamping stranded wires. There is a complete set of what the stranded wire does not like - and the rotational movement, and the uneven surface of the screw, and the dotted uneven pressure. Maybe everything is fine, special if the current is small, and maybe not lucky and half of the wires will remain from the wire. Next you know.
    - It is necessary to select the size under the cross section of the wire. The wire does not fit into too small a diameter, and it is inconvenient to clamp too large, worse contact and more freedom - the risk that the wire will fall out or break off.
    - If a little more tightly clamped, hard, but fragile brass easily cracks. What is fraught with bad contact, and ... Well, you understand.
    - Do not pay attention to the plates with currents when buying. They are lying. Divide the current by two, and better by 3.
    Cost: from 10 to 50 rubles.

  3. Solder paste (without using a soldering iron)
    Solder paste (solder paste) is a mechanical mixture of solder powder, binder (or lubricant), flux and some other components.
    To connect the wires with solder paste, you need to twist the connecting wires, spread the solder paste on the twist and heat the twist with a conventional lighter. Because the solder is in a powdered state, the fine solder particles are melted, forming a welded joint.
    Video - how to use solder paste.
    Solder Paste Overview:the firstandsecond.

  4. Lighter autogen (without using a soldering iron)
    The autogenic lighter is a type of turbocharger, in which the barrel (burner barrel) is turned horizontally, at an angle of about 90 degrees to the body of the lighter.
    Attached ImageAttached ImageAttached ImageAttached Image
    Thanks to the design, the flame of a lighter reaches a temperature of 1300 degrees Celsius and easily melts the solder. It is enough to twist the connecting wires, wrap the twist with solder with rosin inside (it is desirable to use solder with rosin inside for a more reliable connection) and heat the twist with an autogen lighter. Because the temperature of the flame is very high solder melts, forming a welded joint.
    Video - how to solder the wires using the autogen lighter.

  5. Soldering with a soldering iron
    The cheapest (a soldering iron can be purchased for 150 rubles, flux and solder another 50 rubles. As a result, the minimum required for soldering will require about 200 rubles) and a reliable (with at least minimum soldering abilities) method of connecting wires.

  • I also advise you to read the articles on how to connect the wires:the firstandthe secondarticle.
  • Wires Insulation Ways
    1. Insulating tape. Standard for wire insulation.
    2. Heat shrinkable tubing. Made from materials based on thermopolymers that have the property of shrinking when heated with hot air, open flame or in hot water. Produced in the form of tubes of different diameters. The tube is put on before connecting the wires, the wires are connected, the tube moves to the junction of the wires and heats up. When this occurs, the tube is seated (when heated, the diameter of the tube decreases by a factor of two or more, depending on the type of tube), the tube reliably fits the junction of the wires and insulates the wires.
    Shrinkable tubing articleandshrink tubing video.
    You can sit down using a lighter or a building dryer (in fact, it sits perfectly well with a regular hair dryer. We remove the hair extension from the hair dryer, turn on the hair dryer to the maximum and bring it to the tube 1-1.5 cm away

Homemade cable for simultaneous charging and connecting peripherals

Factory cable for simultaneous charging and connecting peripherals
If you can not make a homemade cable to simultaneously charge and connect peripherals, then you have 2 options:
  1. Build a "constructor" from a standard USB hub and standard cables

    USB-hab to simultaneously charge the tablet and connect peripherals without soldering and redoing the wires- only standard cables are used, no need to re-solder or redo anything. Pay attention to the pros and cons of such a hub (Under increased load, the tablet may be discharged, but much slower than during battery operation. With a small load, the tablet charges, but very slowly).

  2. Buy the ONLY 3 factory USB hub for simultaneously charging and connecting peripherals
    Remember: Conventional USB hubs cannot simultaneously charge a tablet and connect peripherals to it.
    ONLYThe exception to this rule is the 3 USB hubs tested in our topic:
    1. USB - OTG Hub for Samsung Galaxy S5 / Note 3 Smartphones(it works on our tablet because it has a nonstandard wire layout that is different from the one used in all other USB hubs).
    You can buy it onaliexpressandebay.
    ATTENTION:Do not confusewith such a hub(as you can see it does not have a switch). It cannot simultaneously charge and connect peripherals (just like all other hubs). Please note that it does not have a switch, this hub will have to be “finished” by itself.according to this instruction.
    2. U2271 note3 n7100 micro usb otg- tested on our tablet by the userdimain008 (more in this post);
    3. 10070TW Acasis H027 Mobile Tablet PC Charging Cable OTG Micro USB HUB 3 Connector (s) Simultaneous Charging Transmisson Cable FS- tested on Pipo w2f tablet by many users, including the userdmn8484, on our tablet should also work (more in this post).
    Possible applicants
    There is 1 hub that CAN BE will work on our tablet, BUT nobody has checked it yet. Buy and check at your own risk. If it works - post in the topic.
    1. There is a similarhub for note 3maybe it will also work on our tablet (this is just a guess, no one has checked it)


ATTENTION: For owners of Android & iOS devices: It is NOT POSSIBLE to make the cable for simultaneous charging of the tablet and connection of peripheral devices. You can only connect the periphery to them (more details under the spoiler).
For owners of Android & iOS devices
Cable for simultaneously charging the tablet and connecting peripheralsNOT POSSIBLEmake for Android & iOS devices. You can only connect the peripherals to them.
  • For owners of Android devices
    At the same time, it is impossible to charge Android devices and connect peripherals to them. Or you
    use OTG, or charge your device, because OTG-controller can not work on data exchange and charging, because gives food ..
    You can also connect peripherals using USB-Habs with additional power, which allow you to connect peripherals that require a lot of power to work (for example, some external hard drives, etc.)
    To connect peripherals, it is necessary that your Android device supports USB Host OTG function (Samsung Galaxy S series smartphones, starting with Galaxy S2, Note series and many other smartphones from other companies, but not all, have this function (check online, Does your smartphone support this function))
    USB Host OTG
    USB Host OTG (abbr. From On-The-Go) is a further extension of the USB 2.0 specification, designed to easily connect USB peripheral devices to each other without the need to connect to a PC.
    That is, we can connect a USB flash drive, mouse, keyboard, card reader, etc. to the phone.
    There is a SEPARATE topic, where everything is detailed:Connection of peripherals and peripherals requiring additional power for Android devices(This is a theme for the Samsung Galaxy S2, but is also relevant for owners of other Android devices).
    There are already ready USB-Habs that allow you to connect peripheralsoverview of one of these hubs.

    You can use a USB-Hab with additional power - the additional power of the hub will go to the work of the peripherals, reducing the consumption of the connected power peripherals from the smartphone. So When using USB-Hab with additional power, the phone will also be discharged as if nothing was connected to it.

    As an alternative, I can offer to charge a smartphone, and connect peripherals to a smartphone via Bluetooth (now you can connect keyboards, mice, some gamepads, some printers, etc.) to a smartphone via Bluetooth.

  • For owners of iOS devices

About bypassing the inability to work peripherals, regardless of the state of the memory connection.

Have you tried to assemble such a scheme or is it a theory?

we have a Lenovo tablet tried a bunch of OTG cables and charging one-time

If you do normally, then at least you need to simultaneously eliminate the connection through one plug and unplug and charge: D

Good day to all!
The question is this: when installing a Windows for some reason, I started to lose the connection of the otg-cable with a flash drive. After trying to eliminate this matter through the BIOS, we have: the tablet does not respond to otg, does not respond to the micro-usb keyboard, does not turn on the BIOS from the volume buttons. Rapid replacement of the charging cable with otg when turned on did not bring results. After turning on the inscription "no bootable device found. Hit any key" and silence. Is it possible to fix the problem with any usb hub / charging combined? Or maybe another is a solution to go into the BIOS / run the installation flash drive?

...brick!
In the themes on the tablets a bunch of moans about this.
Not only disconnecting USB, but supposedly in general, any change to the BIOS with preservation can lead to this effect - the entire USB bus is cut down.
The BIOS chip is non-volatile, it is hard to reset (the options are described with short legs), many had to buy a new chip, flash it and replace it on the board. : girl_cray:
Well, the hub does not help - the USB bus is disabled.

So it happened. I did not have time to experiment with simultaneous charging and a pair of devices. Conveniently, probably: rolleyes:

Hello! It is necessary to connect both ethernet and power to the tablet at the same time. How can I do that? Perhaps there are already some ready-made cords / adapters?
So far, unfortunately, it turns out to do either the first or the second.
I tried this scheme: microUSB-USB, USB-Ethernet. Ethernet works (logically). How to add a tablet without soldering to this circuit? What adapters / hubs to buy?
Thank you in advance!

Any active hub will do. I have a micro USB socket as a power connector. Looks like that:
DEXP Ursus 7W - Discussion (Post by lerron # 71801036)
The yellow USB adapter mom-mom was bought in DNS.
But it is possible to solder a piece of micro USB cable into the most common hub in parallel with the standard USB.
We insert the micro into the tablet, the standard tail into the 5 volt adapter.

Is it possible to do for USB Type-C at the same time charging (or just keeping the charge level) using USB peripherals (flash drives, etc.) from the splitter cable, considering that there is no ID pin in USB-C? The video demonstrates the implementation of this for Micro USB:

Why not try a ready-made hub with external power supply? Type of such:

These do not work. They have either charging or OTG. The video specifically soldered resistor to fool the phone.

And, pure Chinese, albeit on an Intel platform, but with Android in stock.
In Android tablets, it is usually either a charge or an OTG.
Rarely passes the option with a resistor between the contacts ID and GND.

Tell me. There is an idea to include a tablet on Windows in the car audio system. There is a processor with an input for the audio signal. If the sound output from the tablet is better, then the quality is better than through optics and so on. But ... Is there any possibility to organize the charging of the tablet and the sound output at the same time using a cable?

At the same time and charging the tablet and sound output by us?

Yes, all the same - what's the difference, flash or sound processor?
Or turn on through a hub with external power.
But I would be too lazy to fuss in a wheelbarrow ...

Hello, guys. A lot of websites have climbed and could not really find this adapter. Can anyone poke noses that really work? .i so that you can insert the usual flash memory for example with movies and watch and so that the charging goes. Thanks in advance
