Description

[Detailed description of the invention] This invention incorporates, for example, a radio receiver, a game watch, etc., each having an independent function in each housing that is connected via hinges etc. so that they can be opened and closed.
The present invention also relates to an electrical device having a common battery built into one of the casings.

When an electric device that is a foldable combination of two different types of electric devices shares a battery as a driving power source, it is necessary to connect both electric devices with a power cord. In this case, in order to prevent excessive tension from being applied to the power cord when both devices are opened and closed, simply wiring the power cord with some slack will cause the power cord to become loose when opened and There is a risk of it getting caught on something, and it is also unfavorable in terms of appearance. There is also a risk that the power cord may be caught between the casings of both electrical devices and cut when folded.

This invention was made with the aim of solving the above problem, and its gist is as follows:
The power cord led from the casing of one electrical device to the casing of the other electrical device is straddled between the two casings with some play, and a stopper is secured to the power cord in either casing. In addition to this, an elastic means is provided that always urges the power cord to be drawn into the housing through this stopper, and prevents the power cord from loosening at the straddling part when both housings are opened and closed. Therefore, it is an object of the present invention to provide an electrical device that has a good appearance and is characterized by being able to prevent the power cord from being accidentally disconnected.

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 is a perspective view showing an example of the electrical device of this invention, which is a combination of a radio receiver and a game watch that can be opened and closed. That is, the first housing 1 constituting the radio section and the second housing 2 constituting the game watch section are connected so as to be openable and closable, for example, by hinges 3, 3, and the first housing A power cord 5 extending from the common battery 4 side built in the body 1 is straddled into the second housing 2 via the hinge part, and the other end of the power cord 5 is connected to an electronic component of the game watch (not shown). It is connected to. In this case, the power cord 5 is straddled with some play at the hinge part, so that it can expand and contract as the housings 1 and 2 are opened and closed. That is, in the first housing 1, as shown in FIGS. 2 and 3, a stopper 6 formed of, for example, a brass ring is fixed to a part of the power cord 5 by crushing or the like. On the other hand, on the top surface of the support column 7 that stands up from the bottom of the housing 1, there is a leaf spring 9 whose tip engages with the top surface of the stopper 6 and constantly biases it downward.
are fixed with screws 8. Therefore, the stopper 6 and the leaf spring 9 work together to always urge the power cord 5 to be drawn into the first housing 1,
This prevents the power cord 5 from loosening at the straddling portion when both the casings 1 and 2 are opened and closed. In this case,
An auxiliary stopper 6a is fixed to a part of the power cord 5 in the other housing 2, and the leaf spring 9
The elastic force prevents the power cord 5 from moving more than necessary when the power cord 5 is drawn into the first housing 1.

In the above embodiment, a case has been described in which a leaf spring 9 is used as the elastic means, but it does not necessarily have to be a leaf spring 9. For example, as shown in FIG. A compression spring 9a may be compressed between the panel 10, or a tension spring 9b may be stretched between the lower part of the stopper 6 and the bottom of the casing 1, as shown in FIG. A similar effect can also be obtained.

In the above embodiment, the stopper 6 and the leaf spring 9 as elastic means are arranged in the first casing 1, that is, on the side of the radio receiver. Of course, you can do so.

As explained above, according to the electrical equipment of this invention, the power cords that are led from the casings of the electrical equipments that are connected to each other in an openable and closable manner to the casings of the other electrical equipment are connected to each other with play. A stopper is fixed to the power cord in one of the casings, and an elastic means is provided to always pull the power cord into the casing via this stopper. It is possible to prevent the power cord from becoming loose at the straddling part when the housing is opened and closed, and it is possible to improve the external appearance in the open state, that is, in the use state, and
Excellent effects such as being able to prevent accidental disconnection of the power cord when opening and closing are obtained, and its utility value is remarkable.
