Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a cable connection device used for a LAN (local area network or local area network).

[0002]

[Prior art]

 In recent years, companies and the like often have a LAN connection connector on the wall of a conference room or laboratory, and in such a configuration, a portable personal computer such as a notebook computer is connected to the local network via the wall connector. You can connect and access any device while conducting meetings or experiments to see the necessary data or share the Internet environment.

[0003]

[Problems to be solved by the invention]

 However, when a portable personal computer is used in a conference room or a laboratory, the distance from the wall connector to the personal computer may be considerably long, so it is necessary to use a long LAN cable, and lay the cable on the floor. In doing so, it is necessary to route the cable along the floor as much as possible so as not to disturb the walk, and it is also necessary to treat the surplus part of the cable, which makes the handling unexpectedly troublesome. there were. Therefore, an object of the present invention is to provide a LAN cable connection device which is extremely easy to handle a cable regardless of the distance from a connector to a portable personal computer and is easy to clean up after use. Things.

[0004]

[Means for Solving the Problems]

 As shown in FIG. 1, the LAN connection device according to the first aspect of the present invention is provided with a spring 3 or a handle 2 for winding in and a drum 3 equipped with a LAN cable connection connector 5 on one end surface. And the connector 5 is exposed to the opening 1 a provided in the casing 1, and one end of the LAN cable 4 wound around the drum 3 is inserted into the inside of the drum 3 from the notch 3 b provided on the peripheral surface of the drum 3. The LAN cable is connected to the LAN cable connector 5 (that is, a connector for connecting a portable personal computer) from the inside, and the other end of the LAN cable 4 is extended out of the casing 1 so as to extend and contract. The plug 6 connected to the end of the LAN cable 4 can be inserted into a connector 7 for connection to another device (for example, a wall connector). What it is obtained by improving the put away without permission of the cable at the time of routing the LAN cable from the wall connector 7 or the nearest LAN connection for the hub to a portable personal computer.

The LAN connection device according to the invention of claim 2 rotates the drum 3 equipped with a hub 7 having a plurality of LAN cable connection connectors 5 on one end surface into the casing 1 as shown in FIG. The hub 7 is freely stored, the hub 7 is exposed to an opening 1 a provided in the casing 1, and one end of the LAN cable 4 wound around the drum 3 is cut out from a notch 3 b provided on the peripheral surface of the drum 3. To connect to the cascade connection part (not shown) of the hub 8, and the other end of the LAN cable 4 is pulled out of the casing 1 so as to be extendable and contractible, and the plug connected to the end of the LAN cable 4 is connected. 6 can be inserted into the wall connector 7 so that a plurality of persons can connect their personal computers to the network through the device at a meeting or the like. is there.

[0006]

[Embodiment of the invention]

 FIG. 1 shows an embodiment of a LAN connection device according to the present invention. A substantially cylindrical casing 1 has an opening on one side, and a structure for rotatably supporting a drum 3 inserted from this opening 1a. Has become. That is, the drum 3 has one end of the cylindrical main body loosely fitted to a bearing 1b recessed in the side wall of the casing 1, and a flange 3a formed at the other end is provided on the periphery of the circular opening 1a of the casing 1. The plurality of projections 9 are engaged with each other, and are rotatably held in the casing 1.

One end surface of the drum 3, that is, the outer surface of the flange portion 3 a is exposed to the opening 1 a of the casing 1, and a connector 5 for plug connection has a plug insertion port in the drum end surface 3 a on the flange side. It penetrates outward. A long (for example, 7 to 8 m) LAN cable 4 is wound around the peripheral surface of the drum 3, and the end on the winding side is drawn into the inside of the drum 3 from a notch 3 b formed in the body surface of the drum 3. And is connected from the inside to a connector 5 for connecting a short cable exposed on the drum end face 3a. If an extension connector having plug-in jacks at both ends is used as the connector 5, the long LAN cable 4 and the connector 5 can be easily attached and detached during maintenance or the like. The end on the rewinding side of the LAN cable 4 is extended and retracted out of the casing 1 through a cable extraction hole 10 provided in the lower part of the casing 1 and is extended and retracted by a plug 6 provided at the end thereof. It is designed to be connected to the wall connector 7. A handle 2 for winding the unwound LAN cable 4 around the drum 3 is provided on the drum end face 3a. Instead of the handle 2, a handle for automatic winding which is usually used in a vacuum cleaner or the like is provided. Use of a spring and brake mechanism makes handling easier.

In use, as shown in FIG. 2, first place the LAN connection device X near a portable personal computer, pull out the long LAN cable 4 by an appropriate length, and remove the plug 6 at the end. It is inserted into the wall connector 7. Next, the LAN connection device X and the portable personal computer Y are connected by a short LAN cable 11 of about 1 to 2 m. That is, the plug 6 provided at one end of the short cable 11 is inserted into the connector 5 of the LAN connection device X, and the plug provided at the other end is connected to the LAN adapter of the portable personal computer Y. It is inserted into the connector.

FIG. 3 shows another embodiment of the present invention, in which a plurality of portable personal computers can be connected to a LAN connection device. In the figure, the casing 1 is divided into upper and lower parts, the cover 1c is opened, and the drum 3 can be attached / detached. The hub 8 having a plurality of short cable connectors 5 on the drum end surface 3a. A repeat type hub or a switching type hub is provided, and an insertion port of the hub 8 is exposed to the opening 1a of the casing 1. The end on the winding side of the LAN cable 4 pulled into the inside of the drum 3 is connected to the cascade connection terminal 8a of the hub 8 (a terminal for connecting hubs, and the transmission side and the reception side are connected crosswise. Are connected). In the figure, reference numeral 12 denotes a battery power supply mounted inside the drum 3 for supplying power to the hub circuit. According to the configuration of this embodiment, a plurality of persons can connect their own personal computers to the local network through this apparatus, and when the length of the long cable 4 is not enough, this LAN connection apparatus X can be used in multiple ways. It is also possible to add several cascade connections. In the present embodiment, the cover 1b can be opened and the drum 3 can be turned by hand when the drum 3 is wound, so that the handle 2 in FIG. 2 is not necessarily required.

[0010]

[Effect of the invention]

 According to the present invention, as described above, the LAN cable can be extended to an arbitrary length when the portable personal computer is connected to the wall connector or the nearest LAN connection hub. There is an advantage in that the cable can be arranged in a good manner without the need to tie up the cable, and the end of the cable after use is very simple. In the case of equipping with, there are advantages that multiple people can connect their personal computers to the local network or the Internet at the same time, and that this device can be extended multiple times and the cable can be run long.
