According to one embodiment of the present invention, the first connection 110 may also be connected to one of the electronic devices 300 listed above. For example, the power supply unit 200 connected to the first connection unit 110 may be configured as a smartphone, and the electronic device 300 connected to a part of the second connection unit 130 may also be configured as a smartphone. In this case, the power charged in the smartphone connected to the first connection unit 110 can be transmitted to the smartphone connected to the second connection unit 130 through the multi-charging cable 100.

2 is a circuit diagram showing an internal configuration of a first connection unit 110 according to an embodiment of the present invention.

Referring to FIG. 2, the first connection part 110 may include a chip bead 111, a common mode line filter 112, an ESD protection device 113, a capacitor 114, a varistor, and the like. In addition, the first connection part 110 may further include a resistor, an inductor, an additional capacitor, a diode, and the like, which are basic circuit elements.

The chip bead 111 plays a role similar to an inductor, but it is a chip type device formed by using ferrite differently from an inductor. Since the chip bead 111 has an inductance, the impedance value increases at a high frequency. Therefore, the chip beads 111 can perform a role of removing high frequency noises. According to an embodiment of the present invention, the chip beads 111 may be connected to the Vbus terminal in the first connection part 110 to reduce the high frequency noise input from the power supply part 200.

The common mode line filter 112 may be connected to the data line to remove noise that may occur in the data line. The common mode line filter 112 may serve to cancel the common mode noise of the data lines D +, D-. According to one embodiment, the common mode line filter 112 may be configured in the form of a transformer with a winding ratio set to 1: 1, thereby increasing the impedance of the coupling path and effectively eliminating high frequency noise.

The ESD preventive device 113 can prevent the device in the multi-charging cable 100 from malfunction due to excessive electrical stress due to the electrostatic discharge. Electrostatic discharge (ESD) refers to a phenomenon in which a charge moves for a very short time just before a charged object comes into contact with or contacts an object charged with a charge of a different polarity due to a specific charge.

The ESD protection device 113 may be configured to include a TVS (Transient Voltage Suppression) diode, which is one type of diode. When an instantaneous overvoltage is applied, the TVS diode can perform a function of clipping a voltage of a predetermined value or higher to a predetermined voltage to prevent the elements in the circuit from being damaged.

FIG. 3 is a diagram showing a structure of a distributor 120 according to an exemplary embodiment of the present invention, which is classified into an interior and an exterior.

3, the distributor 120 includes a power distributor 121, a connection sensing unit 122, a data path changing unit 123, a data path adjusting switch 124, and a power concentration switch 125 Lt; / RTI >

FIG. 3 (a) is a view showing functional units performing separate functions inside the distributor 120, and FIG. 2 (b) is a view showing the outside of the distributor 120. FIG.

The power distributor 121 may adjust the amount of electric current or the amount of electric power delivered to the plurality of second connection units 130 to be uniform. The power distributor 121 may be configured such that the electronic device 300 is connected to the second connection unit 130 of the plurality of second connection units 130 via the connection sensing unit 122 It is possible to judge whether or not it is.

The power distributor 121 distributes the amount of electric current or the amount of electric power to all the second connection units 130 connected to the electronic device 300 according to the state of the power concentration switch 125 located outside the distributor 120 The voltage to be applied to the second connection unit 130 indicated by the power concentration switch 125 and the amount of the current to be transmitted are adjusted so as to become the rated voltage and the rated current respectively, The amount of electric power or the amount of electric current to be transmitted to the second connection portions 130 not indicated by the first connection portions 125 may be uniform.

That is, the power distribution unit 121 can differentially adjust the charging speeds of the electronic devices 300 connected to the plurality of second connection units 130 based on the state of the power concentration switch 125. In this process, the power distribution unit 121 divides the charging rate of the electronic device 300 connected to the second connection unit 130 selected by the power concentration switch 125 into the second The charging speed of the electronic devices 300 connected to the connection portions 130 can be controlled faster. According to one embodiment, only the electronic device 300 connected to the second connection part 130 selected by the power concentration switch 125 based on the state of the power concentration switch 125, And charging of the electronic devices 300 connected to the plurality of second connection units 130 not selected by the power concentration switch 125 can be performed by a general charging method instead of a rapid charging method .

According to one embodiment, the power divider 121 may apply its own current distribution algorithm. More specifically, the power distributor 121 may assign a first concentrated weight to the second connection unit 130 connected to the distributor 120 whether the second connection unit 130 is the second connection unit 130 set in the power concentration switch 125 have. For example, if the second connection unit 130 set at the current power concentration switch 125 is of the USB-C type and the second connection unit 130 connected to the current distributor 120, two of the USB-C type and 5pin type If the electronic devices 300 are connected to the second connection unit 130 corresponding to the USB-C type, the power distribution unit 121 can apply a predetermined concentrated weight (for example, 1.5 times) have.

In addition, the power distributor 121 may apply the second lumped weight based on the amount of charge of the electronic devices 300 connected through the current distributor 120 and the second connections 130. [ For example, when the amount of battery charge of the electronic device 300 connected through the second connection unit 130 of the USB-C type is 70% and the battery capacity of the electronic device 300 connected through the 5-pin type second connection unit 130 If the charge amount is 10%, the power distribution unit 121 can apply more concentrated weights to the electronic device 300 that has the current battery charge amount. In this case, the power distribution unit 121 applies the second centralized weight based on the difference between the battery charge amount of the smallest battery charge amount among the currently connected electronic devices 300 and the battery charge amount of the specific electronic device 300 can do. According to various embodiments, the application of the second lumped weight that can be applied to a particular electronic device 300 is as follows.

W _n = (C _max -C _min ) / C _n

W _n : second weight of a specific electronic device (n = natural number)

C _max : the highest battery charge (%) among electronic devices

C _min : the smallest battery charge (%) among the electronic devices

C _n : Battery charge (%) of a specific electronic device

For example, if the electronic device 300 connected to the distributor 120 has a battery charge of 90%, 50%, 10%, respectively, then the power distributor 121 will have a value of 80% minus 90% to 10% And weights of 0.89 times, 1.6 times, and 8 times of the charge amount of each electronic device 300 divided by 80% can be applied to each electronic device 300. According to one embodiment, the power divider 121 may adjust the amount of current or charge rate to each electronic device 300 as a ratio of the calculated weights. In order to perform such operations, the distributor 120 or the power distributor 121 includes a program and algorithm for collecting respective battery charge amount information from the electronic device 300 through the second connection 130 .

Then, the power distributor 121 can set the rapid charge / general charge state by comprehensively considering the first centralized weight and the second centralized weight for each of the second connection units 130 or the electronic device 300 . For example, the power distributor 121 can rapidly charge the electronic device 300 connected to the second connection unit 130 having the largest value obtained by adding the first concentrated weight and the second concentrated weight, respectively.

In addition, the distributor 120 may be additionally provided with a button for automatically setting the current distribution algorithm. For example, an 'automatic switch' may be further included. The current distribution algorithm and the weighted comparison operation can be performed by the processor and the memory included in the power distributor 121 or the multi-charge cable 100.

The connection sensing unit 122 may sense the second connection unit 130 connected to the first connection unit 110 and the plurality of second connection units 130 to which the electronic device 300 is connected, To the power distributing unit 121 and the data path changing unit 123. [

The data path changing unit 123 may set a route for performing data transmission according to the electronic devices 300 connected to the first connection unit 110 and the plurality of second connection units 130. [ For example, if the power unit 200 or the electronic device 300 is connected to the first connection unit 110 and the electronic device 300 is connected to only one of the second connection units 130, The changing unit 123 may set a data path so that data can be transmitted and received between the first connection unit 110 and the second connection unit 130 connected to the electronic device 300. [

The data path changing unit 123 may switch the data path changing unit 123 between two of the plurality of second connecting units 130 in a state where the power unit 200 or the electronic device 300 is not connected to the first connecting unit 110. [ When the electronic device 300 is connected to only the second connection unit 130, a data path can be established so that data can be transmitted and received between the two second connection units 130 connected to the electronic devices 300.

The data path changing unit 123 may adjust the data transmission path according to the state of the data path adjusting switch 124 located outside the distributor 120. For example, when the first connection unit 110 is connected to the computer and the plurality of second connection units 130 are connected to the smart phones, the data path changing unit 123 switches the data path adjustment switch 124 The data transmission path can be adjusted so that data communication between the smartphone connected to the second connection unit 130 pointed to and the computer connected to the first connection unit 110 is performed.

Referring to FIG. 3 (b), the distributor 120 according to an embodiment of the present invention may include a data path control switch 124 or a power concentration switch 125 on the outside thereof.

The data path conditioning switch 124 and the power concentration switch 125 may include all kinds of physical / electrical devices capable of performing various types of switch, button, or selection among various options, regardless of its designation.

According to an embodiment of the present invention, the data path control switch 124 selects one of the plurality of second connection units 130 and connects the electronic device 300 connected to the selected second connection unit 130 to the first connection unit 130 110 to control the data path to perform data communication with the electronic device 300 connected thereto. The setting of the data path may be performed by the data path changing unit 123 that senses the state of the data path adjusting switch 124. In the case where the second connection unit 130 is composed of three as shown in FIG. 1, for example, in FIG. 3 (b), the data path adjustment switch 124 is provided between the plurality of second connection units 130a, 130b, Depending on where you are selecting, the data path may change. In FIG. 3 (b), the data path adjustment switch 124 is shown to be able to select one of the second connection portions 130 each composed of 5-pin, 8-pin and USB-C type charging terminals, And the second connection unit 130 configured by the charging terminal of the first type is selected.

According to an exemplary embodiment of the present invention, the data path adjustment switch 124 may be configured as one button, unlike the example of FIG. 3B. In this case, when the user applies a constant pressure to the button The second connection unit 130 capable of performing data communication with the first connection unit 110 may be sequentially changed. That is, when the user is able to perform data communication between the first connection unit 110 and the second connection unit 130a, if the user presses the data path adjustment switch 124 once, The second connection unit 130b can be changed and the second connection unit 130c capable of data communication with the first connection unit 110 can be changed when the user presses the data path adjustment switch 124 again.

According to another embodiment of the present invention, the data path adjustment switch 124 may be configured to select two paths instead of one. In this case, the multi-charging cable 100 may operate in a state where two paths selected by the user are connected and data communication between the paths is performed. For example, the user can select one of the first connection unit 110 and the plurality of second connection units 130 to control the data path so that data communication between the selected paths is performed, and the first connection unit 110 It is possible to select two of the plurality of second connection units 130 without selecting it and adjust the data path so that data communication between selected paths is performed. In the case where the data path adjustment switch 124 is configured to select two paths, the data path adjustment switch 124 may be configured to have a plurality of paths, or two paths may be configured to be selectable from one switch have.

According to an embodiment of the present invention, the power concentration switch 125 selects one of the plurality of second connection portions 130 to select the amount of electric current or the amount of electric charge Can be managed preferentially.

In the conventional chargers, there is a problem that an unbalance occurs between the amount of electric current or the amount of electric power transmitted to a plurality of electronic devices in charging the plurality of electronic devices at the same time. There has been a problem that the charging speed of each electronic device is reduced when a plurality of electronic devices are charged by one charger as compared with when charging is performed.

The power concentration switch 125 is provided for solving the above problems. The user selects the electronic device 300 desired by himself / herself or the second connection 130 connected to the electronic device 300, The charging of the electronic device 300 connected to the selected second connection unit 300 or the selected second connection unit 130 may be preferentially performed. That is, the voltage and the amount of current delivered to the second connection unit 130 indicated by the power concentration switch 125 may be adjusted to be the rated voltage and the rated current.

According to one embodiment, the electronic device 300 selected in accordance with the state of the power concentration switch 125 or the electronic device 300 connected to the selected second connection 130 is charged in the rapid charging mode, The electronic device 300 connected to the electronic device 300 or the unselected second connection part 130 may be charged in a general charging mode rather than a rapid charging mode.

According to one embodiment, the power concentration switch 125 may be set to a neutral state in which none of the plurality of second connections 130 is selected.
