Detailed ways

The chargers in Figure 1 and Figure 3 represent various mobile phone chargers. Some fast chargers do not use the charging line 4, but the switch 2 can be used. The charging block 1 of the charger is equipped with a switch 2 on the surface (the switch 2 can be installed on any side of the transformer block, preferably upward or/and on any side), and the switch is used to cut off the conduction plug 3 and the inside of the transformer block. The electrical connection of a plug-connected circuit. The switch can be various existing switches (button type, touch type, mechanical type, etc.), and can also be various structures that can realize circuit on-off (such as the following switch wires). The switch can be one pole that cuts off the power supply or two positive and negative poles that cut off the power supply at the same time. A general switch cuts off one pole of the power supply. In Figure 3, the contact 11 used to control the power switch in the switch is made from one to two, and each contact controls the on-off of one power supply pole, so that the two poles of the power supply can be controlled. switch simultaneously. Figure 3 is equivalent to combining two switches into one, of course, two switches can also be used to control the on-off of the two poles of the power supply.

The internal circuit of the charging block of the charger refers to the circuit installed in the charging block. Because the transformer circuit in the charging block uses a coil, it is old-fashioned, and now there are many other lightweight transformer circuits and methods, so the internal circuit of the charging block does not include the structure of the internal circuit of the charging block connected to the plug. , excluding the configuration of the coil.

In Figure 3, in order to illustrate the problem and clearly show the circuit connection, the plug, switch, and charging block are drawn separately. In fact, the three (except the plug installed on the charging line) are integrated.

In Fig. 5, a schematic diagram is drawn of the circuit connection between the charging line and the circuit disconnection point 12 between the plug and the charging block.

Generally, a switch has one (or called one group, one and one group represent all contacts of a switch) contacts 11, which are used to control the on-off of the switch. The switch can be provided with two (or called two groups) contacts 11 .

In Figure 1 and Figure 3, the switch and the switch line structure are drawn together. In fact, as long as there is one structure, two structures are also acceptable. In Figure 3, the circuit structure of the switch is generally drawn. In addition, in order to clearly show the circuit structure, the switch and the charging block are drawn separately, but they are actually installed together.

In Fig. 1 and Fig. 3, the charging line 4 of the charger is juxtaposed and there are two switch lines 5, and the outside of the switch line and the charging line are wrapped with insulating skin to form a bus or separately wrapped into two buses. The electrical connection between the plug 3 and the internal circuit of the charging block is disconnected, one end of a switch line is electrically connected to the plug 3 of the charging block (the part where the plug enters the charging block), and one end of the other switch line is connected to the internal circuit of the charging block. The disconnected end of the plug is electrically connected (that is, one end of the two switch wires is electrically connected to the plug and the two ends of the disconnected end of the internal circuit of the charging block, and the other end of the switch wire is connected or disconnected to control the power supply of the internal circuit of the charging block. The structure of whether or not. A group of switch lines 5 can be used to control the on-off of one power pole (the plug corresponds to the positive and negative poles of the power supply), and another set of switch lines 6 can be used to control the on-off of the other power pole.

In Figure 2, the connection between the switch line and the charging plug (the charging plug is used in conjunction with the charging port of the mobile phone) is as follows: an electrode 9 (inner surface or/and outer surface) is installed at the end of the charging plug, and an electrode 10 is installed near the electrode 9. After the mobile phone is fitted with the charging plug, the pressure electrode 9 and/or the electrode 10 are deformed, so that the two electrodes are conducted, and the breakpoint between the plug 3 and the internal circuit of the charging block is conducted. Another set of switch wires 6 can also have a corresponding structure. The charging plug in the figure is square, and can also be a structure of various charging plugs such as a cylinder. The electrode 9 or/and the electrode 10 can be made a pit on the surface of the charging plug, partially or completely hidden in the pit (but does not affect the function of the electrode and does not affect the work of the charging plug). The charging contact 8 is the contact used when charging the mobile phone. The electrode 9 and/or the electrode 10 are elastic, and when the charging plug is pulled out, the two electrodes return to the disconnected position.

In Fig. 3, the switch line can also be installed with a switch at any position (the switch has various structures), and the switch is used to control the conduction and disconnection of each group of switch lines. There are two switches, which respectively control a group of switch lines. There is one switch, and the switch has one or two contacts, which are used to control the on-off of one or two groups of switch wires.

In Figure 3, the switch can be installed on the surface of the charging plug.

The switch at the other end of the switch line can be installed on the surface of the charging plug, and the switch can be of various structures.

In Fig. 4, there is a switch 2 on the charging plug, which can be manually operated or controlled by plugging and unplugging the charging port of the mobile phone. The manual operation can be various switch structures, such as touch type, button type, mechanical type and so on.

In Figure 4, there is switch 2 on the charging plug. The switch is controlled by the charging port of the mobile phone. The end of the switch close to the insertion end of the charging plug is basically not higher than the surface of the charging plug, and the end of the switch away from the insertion end of the charging plug is higher than the surface of the charging plug, which does not affect the mobile phone. Inserting and pulling out the charging port (it can also be expressed as: at least a part of the end of the switch away from the insertion end of the charging plug is higher than the surface of the charging plug, and the end of the switch near the insertion end of the charging plug is lower than or substantially flush with the surface of the charging plug. Charging When the charging port of the mobile phone is plugged in, press the higher part of the switch to make the switch conduct; when the switch is not pressed, one or two poles of the power supply are disconnected). In the picture, two switches are drawn on the surface of the charging plug at the same time. In fact, only one switch is required, and of course two can be made. The switch disconnects one or both poles of the conducting power. The surface of the charging plug refers to the inner or/and outer surface. The switch on the surface of the charging plug is pressed to conduct the circuit, and the switch is released to disconnect the circuit. This is a structure controlled by the charging port of the mobile phone.

Of course the present invention can also be used for other objects with transformers (it is better to use transformers without permanent work): as existing transformers (the voltage of some transformers is higher, and a suitable switch 2 can be used. Switch 2 can also be used The wires extend farther away from the transformer and are mounted on other structures.).
