Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a socket used for connecting a power source to an electric device when the electric device is used in a vehicle cabin.

[0002]

[Prior art]

 Various electric devices are used as after-parts in automobiles. For example, there are a wide variety of lights (lighting fixtures), cigarette lighters, televisions, TV antenna sets for diversity, TV receiving boosters, radar detectors, portable CDs, navigation systems, refrigerators, beverage heaters, etc. . The only way to connect the battery power to these electric devices and input the required power in the vehicle interior is to insert the power plug of the electric device into the outlet of the cigarette lighter installed near the driver's seat. , An easy way.

In many cases, it is desired to use a plurality of these power supply devices at the same time, but since there is usually only one outlet for a cigarette lighter in one car, it is not possible to use a plurality of electric devices at the same time. Nor was it possible to use a cigarette lighter and other electrical equipment at the same time. Therefore, it has multiple socket ports (2 ports, 3 ports, 4 ports, etc.) for inserting the power plugs of electric devices, and the plugs at the cord end can be inserted into the outlets of the cigarette lighter of an automobile to simultaneously load multiple electrical devices. Automotive sockets have been developed to supply battery power to vehicles.

FIG. 7 is a perspective view showing an example of such a conventional automobile socket. This automobile socket is provided with a plurality (three in this example) of socket ports 3a, 3b, 3c on the front surface 2 of the socket body case 1, and has both terminals of the plug 4 fitted into the cigarette lighter insertion port of the automobile. It is connected in parallel to each socket port 3a, 3b, 3c through a cord 5. In this example, one of the three socket ports (3a at the right end) is a socket port dedicated to inserting the cigarette lighter 6 and the other two (3b, 3c) are socket ports for inserting the power plugs of other electric devices. Has become. This automobile socket is usually mounted on the dashboard or on the center console so that the front face 2 with the socket opening faces the driver side (so that the cigarette lighter 6 is easy to use). Attach and use the adhesive tape 7 or the like.

In the above example, a plurality of socket ports are provided only on one surface (front surface) of the socket body case, and the insertion of the power plug of the electric device is limited to a certain direction (for example, the driver's seat side). For this reason, depending on the type and usage of the electrical equipment, the handling of the cord may become defective, or the cord may get confused near the driver's seat, obstructing the driver, and making it look unattractive. (If it is installed upside down or sideways, the cigarette lighter will become unusable or difficult to use.) So, not only one side (eg front) of the body case but also other side (eg side, back or top). In addition, one or more socket ports are provided to allow the power plugs of electric devices to be inserted from two directions. FIG. 8 is a perspective view schematically showing the usage state of another example of such a conventional automobile socket. This automobile socket has two socket ports 3a on the top surface 8 of the socket main body case 1, 3b, and the front surface 2 is provided with two socket openings 3c and 3d. In the illustrated example, the main body case 1 is attached to the side of the floor console C on the driver's side with double-sided adhesive tape or the like, the cigarette lighter 6 is attached to the top socket port 3a, and the light P flag P-1 is attached to the socket port 3b. It is used by inserting the plugs P-2 and P-3 of other electric devices into the front socket ports 3c and 3d. It is preferable to install a device such as this light L by inserting a plug into the upward socket port on the top surface of the case from the viewpoint of ease of operation and illuminating the hand. Is unsightly when a plug is inserted into the upward socket, and there is also a risk of breaking the wire or causing a short circuit by hooking the cord. The two-way insertion type automotive socket of this example can be used by selecting the insertion direction of the plug according to the type of equipment and the usage mode. Therefore, compared with the one-way insertion type socket of the previous example (Fig. 7). It has become even easier to use.

[0006]

[Problems to be solved by the device]

 However, the conventional automotive socket as described above is not limited to the one-way insertion type, but even if it is a two-way insertion type, the orientation of the socket port is fixed, so In some cases, it may not be possible to select the optimum plug insertion direction according to the usage pattern, and the wiring cords may become complicated during use, making the interior of the vehicle unattractive and disturbing the driver. It was not possible to fully eliminate the problems such as the risk of disconnection and short circuit caused by hooking the cord. A multi-faceted plug-in type in which the number of faces to be provided with socket ports is increased to 3 or 4 is also conceivable, but this is not practical because the socket structure and internal wiring become extremely complicated, resulting in a significant cost increase. Although it is possible to remove the case by removing the double-sided adhesive tape etc. and replace it so that it is in the proper plug insertion direction, it is very troublesome to remove the once installed, it is too much for the user. Will be troublesome.

The present invention is intended to solve the problems of the conventional automotive socket as described above, and makes it possible to perform a well-ordered and well-equipped device wiring without complicating the socket structure and internal wiring. It is an object of the present invention to provide an automobile socket that can be manufactured and is easy to use.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, an automobile socket of the present invention is connected to a socket body case having a plurality of socket openings and a tip of a cord connected to the socket body case, and is fitted into a car cigarette lighter insertion opening. It is composed of a mating plug and a mounting base that is fixed to a member inside the vehicle compartment and that supports the socket body case, so that the socket body case is oriented in a direction parallel to the surface of the mounting base. And means for supporting the mounting base and changing the direction of the socket in a plane parallel to the surface of the mounting base. The means for changing the direction of the socket mouth has a structure in which the socket body case is swung in a plane parallel to the surface of the mounting base, or the socket body case is provided on the surface of the mounting base. It is attached to the mounting base by inserting it along the guide rail, and once the socket body case is pulled out from the guide rail, it is re-inserted into the guide rail from another direction to change the direction of the socket port.
