[Technical field to which the invention belongs]

 The present invention relates to an AC adapter dedicated to various devices and an AC adapter with a charger that can be used in place of a charger and is compatible with multiple models.

[0002]

[Prior art]

 Conventionally, in order to confirm the operation of various electric devices, it was necessary to connect an AC adapter prepared for each device. In particular, many electrical devices such as cordless telephones are driven by a specified DC voltage, and each device requires a dedicated adapter. The charging function of the secondary battery is built into the main body of the cordless phone.

Conventionally, a dedicated AC adapter has a cord directly extending from the adapter body, and a connection plug for connecting to an electric device is provided at the tip of the cord. The DC voltage converted from the AC 100V of the AC adapter differs depending on the model of various electric devices, and the shape of the connection plug also differs. Even if the voltage and shape are the same, the electrode polarities may be opposite. In this way, because the standards for voltage and connection plugs are not uniform, it is not possible to confirm the operation of various electrical equipment with the same AC adapter, except for using the AC adapter prepared for each electrical equipment. There was no way. Also, the secondary battery stored inside the main body of the cordless phone etc. could not be charged in advance by another charger because the voltage and the shape of the connector differ depending on the model.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the AC adapter with a charger of the present invention, FIG. 2 is a rear view of the same, and FIG. 3 is a plan view of the same. In the AC adapter 1 with a charger, an outlet cable 3 extends from the back surface of the housing 2, and an outlet plug 4 at its tip is joined to an AC100V outlet to obtain AC power. In addition, fuse holders 5 and 6 are provided on the rear surface of the housing 2.

A power switch 7 is provided on the upper surface of the housing 2, and various shapes of charging connection connectors 8, 9 and 10 for connecting the secondary battery 45 are provided as a charging function. When the charging voltage switch 12 is switched to the standard voltage, the charging output switch 12 is turned ON and the refresh button 14 is pressed, discharging is started. During the refresh discharge, the discharge display lamp 15 is turned on, and after the discharge is finished, the discharge display lamp is turned off and the charge display lamp 13 is turned on to start charging.

The voltage changeover switch 16 is a knob for changing the output DC voltage to the standard of the equipment, and the voltage can be changed stepwise by rotating the knob.

On the other hand, as shown in FIGS. 4 to 10, a plug cord suitable for various devices is provided in advance. For example, both ends 24 and 25 of the connection plug cord 23 are round plugs, and the polarities of the external terminal and the internal terminal of the round plug may be reversed depending on the electric device. That is, there are two types, one having a cathode (-) as an external terminal and an anode (+) as an internal terminal, and one having a positive electrode (+) as an external terminal and a cathode (-) as an internal terminal. Therefore, the polarity of the electrical equipment can be changed by arranging the output jacks 17 and 18 into which the common round plug 25 is inserted so that the polarities of the external terminals and the internal terminals are changed so that either polarity can be used. It is possible to select and join the one that is compatible with.

By connecting the round plugs 24 having different connecting plug cord shapes to the input jacks of the electric device 44 and turning on the output switch 19, the AC is converted into a set DC voltage and converted into electric devices. Can be supplied.

As for the shape of the plug of the connection plug cord, there is an MJ plug in addition to the round plug. Therefore, it is necessary to connect the 8-core MJ plug 40 and the 4-core MJ plug 43 of the MJ connection plug cords 38 and 41 to each other. By providing the core MJ output jack 20 and the 4-core MJ output jack 21, it is possible to correspond to an electrical device whose input part is an MJ type.

Among cordless phones provided with a 4-core MJ input jack, there is a device that pulls in a telephone line in addition to a DC voltage from the 4-core MJ input jack. Therefore, by joining the telephone line to the telephone line connection MJ22, the DC voltage and the telephone line can be drawn into the electric device from the 4-core MJ output jack 21 via the MJ connection plug cord 41.

As described above, according to the present invention, the circular plugs 24, 27, 30, 33, 36 on one side of the connection plug cords 23, 26, 29, 32, 35 are connected to the internal terminals in order to be connectable to various devices. The external plugs having different shapes are prepared, and the round plugs 25, 28, 31, 34 and 37 on the opposite side have the same shape so that they can be joined to the output jacks 17 and 18.

[Effect of the invention]

 As is clear from the above detailed description, since the AC adapter with a charger of the present invention does not need to prepare a dedicated AC adapter for each different type of electric device, it is not necessary to use an electric power adapter such as a cordless phone. When the user removes the AC adapter and brings only the electric equipment to the failure diagnosis reception desk to diagnose the failure of the equipment, if the user connects the adapter of the present proposal and supplies the power, the operation of the electric equipment can be confirmed. As a result, it is not necessary to prepare an AC power supply adapter for all electrical devices, and it is not necessary to take the trouble of having the user replace the AC power supply adapter. In addition, when charging the secondary battery by removing it to determine whether the secondary battery is defective or the charging part of the electrical device is defective, the charging function of the present proposal does not require preparing an equivalent electrical device. Rechargeable batteries with different voltage specifications and connector shapes can be charged quickly. Also, when carrying out a business trip failure diagnosis at the user's house, carrying the present plan eliminates the need to carry and manage a large number of articles, and only a lightweight and compact tool box is required. Moreover, even if electrical equipment that requires a new shape of plug is available in the future, it can be used as a replacement for the new model's dedicated AC adapter by adding a connection plug cord with a plug corresponding to the electrical equipment attached to one side. There are various effects such as being able to do.
