Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a cord reel unit in which a small cord reel unit having a power plug fitting is inserted into a power socket and the power cord is pulled out when the electric appliance is used and connected to the power socket of the electric appliance. The present invention relates to a cord reel unit that can be commonly used by being connected to an electric appliance having a power socket that can be connected to.

[0002]

[Prior art]

 Conventionally, the cord reel unit has a function of taking out a power cord of a required length, or storing the power cord inside when the electric appliance is not used to facilitate the handling and storage of the electric appliance. It was a unitary structure with electric appliances. In addition, there was a relatively large cord reel unit that was used separately as a cord extension and used separately from electrical equipment.

[0003]

[Problems to be solved by the device]

 The cord reel device described in the related art had to be provided for each electric appliance in the case of being integrated with the electric appliance, and was used only for the electric appliance. Further, the cord reel device for extending the cord has a problem that it requires a separate space for accommodating itself.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to separate the electric appliance and the cord reel unit, which are conventionally integrated structures, from each other. , It is intended to provide a compact cord reel unit that can be used by being plugged into an external power supply socket and commonly used for all electric appliances that have a connection terminal that can be connected to the power supply terminal of the power cord. .

[0005]

In order to achieve the above object, a cord reel device according to the present invention has a power plug seat 1 to which a pair of power plug metal fittings 5 are fixed, and an outer periphery of its rotary sliding surface. A cord winding case 2 forming a donut-shaped hollow portion is inserted and installed between the cord winding case 2 and the power plug seat 1, and the power cord 3 is wound around the cord winding case 2 in the hollow portion. . One end of the power cord 3 is fixed to the cord winding case 2 and the other end of the power cord 3 is provided with a power terminal 4 to be pulled out from the cutout hole of the power plug seat 1 and to the power plug seat 1 and the cord winding case 2. Has a structure in which an electrical connection is held between the fixed end of the power cord 3 and the power plug fitting 5 even when they are stationary and rotating.

[0006]

[Action]

 This cord reel unit is used by connecting to a power socket provided on a wall surface or the like. When the power supply terminal 4 side of the power supply cord 3 stored in the cord winding case 2 is pulled, the cord winding case 2 rotates around the sliding surface of the power plug seat 1 and the power cord 3 becomes the power plug seat 1 It is pulled out from the cutout part of. The power terminal 4 of the power cord 3 is connected to an electric appliance and used as a power cord for the electric appliance. After use, remove the power supply terminal 4 from the electric appliance and rotate the cord winding case 2 to wind and store the cord winding case 2.

[0007]

【Example】

 Examples will be described with reference to the drawings. A pair of power plug fittings 5 each having a socket terminal-shaped power supply terminal and a plug terminal-shaped power supply terminal on the other end are exposed to the plug terminal-shaped side to the outside, and the power plug seat 1 is fixed to the power plug seat 1. A cord winding case 2 which comes into contact with and slides and rotates is provided by being inserted into a power plug seat 1. The power plug seat 1 and the cord winding case 2 form a donut-shaped hollow portion in the sandwiched portion. In the cavity, the power cord 3 having one end fixed on the cord winding case 2 is wound around the cord winding case 2 to be housed, and the other end is provided with a power terminal 4 for connecting an electric appliance and a power plug. It goes out through the cutout hole in the seat 1. Further, a terminal cover 6 for protecting the socket winding-shaped side of the power plug fitting 5 and holding the inserted cord winding case 2 is fixed on the power plug seat 1. Then, the fixed end of the power cord 3 and the ring plate-shaped conductor ring 7 fixedly provided in the cord winding case 2 are electrically connected to each other, and the conductor spring 8 and the conductor ring which are electrically connected to the power plug fitting 5 are electrically connected. It is slidably contacted by the spring force of the conductor spring 8 so that an electrical connection is always provided between the power plug fitting 5 and the fixed end of the power cord 3.

[0008]

[Effect of device]

 The cord reel device according to the present invention, which is configured as described above, can be commonly connected to all electric appliances having a connection terminal connectable to the power terminal 4 of the power cord 3. Then, the electric power cord is not required for those electric appliances, and the same effect can be obtained as if each electric appliance is provided with a cord reel. This makes it easy to store and handle electric appliances, and enables weight reduction, downsizing, and cost reduction of electric appliances. Furthermore, when multiple types of electric appliances are connected to the same power socket within a short time, such as a washbasin, the effect of reducing the hassle of taking out and storing the electric appliances and power cords is great.
