Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal cover for covering a terminal exposed on the outer surface of a portable telephone, for example, a surface of an information input / output terminal.

[0002]

2. Description of the Related Art Recently, many devices provided with an information input / output terminal for connecting a portable telephone to a device such as a computer are commercially available.

[0005] As shown in FIG. 8, the information input / output terminal 20 is exposed on the outer surface of the telephone body 4. If the information input / output terminal 20 is contaminated with dust, dirt or the like, it is likely to cause a conduction failure. It is known that a single terminal cover 21 as shown in FIG. 9 is used to cover the terminal surface 20 as shown in the end view of FIG. 10 and the front view of FIG. In addition, the code | symbol 14 in a figure shows a charging terminal.

[0004]

However, since the conventional terminal cover is formed as a single unit, there is a problem that the terminal cover separates from the telephone body when the terminal surface is opened and is easily lost.

Accordingly, the present invention has been made in view of the above-mentioned problems, and has as its object to provide a terminal cover which is not likely to be lost even when the terminal surface of the telephone body is opened.

[0006]

According to a first aspect of the present invention, there is provided a terminal cover for a portable telephone, wherein the terminal cover covers a terminal surface exposed on an outer surface of the portable telephone. A fan-shaped rotating plate is connected in a direction perpendicular to one side of the cover body, and a rotating shaft is provided near the center of the fan at the central angle. By providing a click mechanism for positioning, rotating the rotary plate about the rotation axis to open and close the terminal cover, and positioning the start and end points of opening and closing by the click mechanism, the terminal via the rotary plate The cover is connected to the main body of the telephone.

According to a second aspect of the present invention, there is provided the terminal cover of the portable telephone according to the first aspect, wherein the terminal cover is made of plastic.

According to the first and second aspects of the present invention, the terminal cover for covering the exposed terminal surface can be opened and closed by rotating through a rotary plate, and the terminal cover can be opened and closed via the rotary plate. , The terminal cover is not separated from the telephone body, and there is no risk of loss.

Further, since the start and end points of the rotation of the rotary plate are determined by the click mechanism, the closed state and the open state are maintained at predetermined positions. Further, since the terminal cover is made of plastic, molding is easy.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 7 relate to an embodiment of the present invention. FIG. 1 is a perspective view of a mobile phone showing a terminal cover in an open state, FIG. 2 is a perspective view of a mobile phone showing a terminal cover in a closed state, 3 and 4 are perspective views of the terminal cover, FIG. 5 is a cross-sectional view showing a state where the terminal cover is mounted, and FIGS. 6 and 7 are partial cross-sectional views of a mobile phone showing operation of the terminal cover.

The terminal cover 1 of the portable telephone according to the present invention is formed of plastic and has a center angle of about 11 in a direction perpendicular to one side of the rectangular cover body 2 as shown in FIGS.
A 5-degree fan-shaped rotary plate 3 is continuously provided, and a rotary shaft 7 is formed protruding near the center of the central angle. In addition, a click mechanism for fixing the positions of the start point and the end point of the rotation is provided near both ends of the circumference on the opposite surface on which the rotating shaft 7 protrudes,
The click mechanism is provided on the surface of the rotary plate 3 with the engagement recesses 8a, 8b.
Is provided at a position where the opening and closing angle exceeds 90 degrees.

On the other hand, as shown in the sectional view of FIG. 5, an insertion hole 6 for inserting the rotary plate 3 of the terminal cover 1 into the telephone body 4 side.
Are formed, and the insertion hole 6 is formed corresponding to the range in which the rotating plate 3 rotates. A click engaging recess 8 a or 8 on the rotary plate 3 side is provided on a side surface near the entrance of the insertion hole 6.
An undulating engagement projection 10 that engages with b is provided at one location.

On the side of the end of the cover main body 2, there is provided a hook portion 12 for facilitating opening of the cover main body 2.

In the terminal cover 1 having this configuration, when closed as shown in FIG. 6, the engaging recess 8a of the click mechanism engages with the engaging projection 10 as a starting point of opening and closing, and the closed state is maintained. . As shown in FIG. 7, when the cover body 2 is open, the engaging recess 8b engages with the engaging projection 10 as an end point of opening and closing, and the opening state is maintained at a position where the opening and closing angle exceeds 90 degrees. .

By opening the terminal cover 1 from the terminal surface in this manner, it becomes possible to connect the connector 13 that is electrically connected to another device. Reference numeral 14 in the figure indicates a charging terminal.

[0017]

According to the present invention, the terminal cover is configured to be openable and closable with respect to the telephone body via the rotary plate, so that the terminal cover is connected to the telephone body by the rotary plate and separated. Since there is no possibility that the terminal cover is lost, there is no possibility of the terminal cover being lost.

The opening and closing start and end points are fixed to the rotating plate by a click mechanism. Even when the rotating plate is open, a part of the rotating plate is always located in the telephone body, so that opening and closing are stable. Further, since the terminal cover is formed of plastic, molding is easy.
