SUMMARY OF THE INVENTION It is an object of the present invention to address the above-mentioned problems of the structure of the external connection terminal portion of the conventional portable terminal, and there is a possibility that the terminal cover may be broken or lost during use. It is possible to obtain a terminal cover that is easily removable.

[0013]

SUMMARY OF THE INVENTION The present invention relates to a portable terminal having a terminal for external connection, a first elastically deformable portion which is elastically deformed when attached to a main body, and a second elastically deformable portion which is elastically deformed when detached. A terminal cover for covering the external connection terminal having a deformable portion; and an elastically deformable means provided on the main body side for causing the terminal cover to elastically deform.

The terminal cover includes a cover for covering the external connection terminal, and a tongue attached to the main body. The tongue has a first elastically deformable portion and a second tongue.
Characterized by having an elastically deformable portion.

Further, the tongue piece is elastically deformed when the external connection terminal is used.

Further, the first elastically deforming portion is characterized by comprising elastically deforming means in which at least the tongue piece is cut out in a hole shape.

[0017]

FIG. 1 is a diagram showing a terminal cover. A recess 2a for hooking a finger or the like on the terminal cover 2 and opening the terminal cover 2
And a cover 2b for covering the terminal, and a tongue piece 2c for connecting the cover 2b to the main body. Further, a tip surface 21 of the tongue piece 2c, an inclined surface 22 against which the boss 5 of the main body abuts at the time of mounting, and a retaining portion 23 which cannot be easily removed after mounting to the main body. When the boss of the main body opens and closes, it guides the tongue piece 2c to thereby open the terminal cover 2c.
A guide surface 24 for guiding the whole, an elastic deformation hole 25 that is elastically deformed when the terminal cover 2 is attached to the main body 1 so that the terminal cover 2 does not come off with a small force after the attachment.
The terminal guide portion 27 serving as a guide function to the terminal of the main body is integrated with an elastic member (for example, rubber).

The plug insertion opening 3 of the main body 1 between the front surface 1a and the rear surface 1b is closed.

FIG. 2 is a partial cross-sectional view showing the transition of the state in which the terminal cover 2 is fitted to the main body 1. The portion indicated by hatching (upper side in FIG. 2) is the portion covered by the main body 1. is there.
Two pins 5 are integrated on either the front surface 1a or the rear surface 1b of the main body 1.

FIG. 2A is a view showing a state in which the terminal cover 2 is detached and is about to be fitted. Then, when the state proceeds to the fitting, the pin 5 on the main body side comes into contact with the inclined surface 22, the inclined surface 22 is pushed inward, and the elastic deformation hole 25 is deformed (b in the same figure). When the pin 5 further advances, the pin 5 moves over the inclined surface 22 and moves to the vicinity of the retaining portion 23, and since the pressing force that has been pressing the inclined surface 22 disappears, the inclined surface 22 returns to the original position and is deformed. The hole 25 for elastic deformation which has been performed returns to its original shape (FIG. 3C).

Thus, the fitting of the terminal cover 2 to the main body is completed. Since the elastic deformation by the resin such as rubber is used, the terminal cover can be easily fitted to the main body without requiring a large force.

FIG. 3 is a view showing the open / close state of the terminal cover.

FIG. 2A shows a state in which the terminal cover is closed.
The end of the main body 1 covers the lid 2b. That is, when the terminal cover 2 is closed, the terminal cover 2 is on the same plane as the surface of the main body 1, and the terminal cover 2 is integrated with the main body 1 without discomfort (FIG. 5A).

Next, in order to remove the terminal cover, the user hooks a finger, a nail or the like on the concave portion 2a and opens the lid portion 2b. Then, the guide is guided to be drawn straight out by the pin 5 in contact with the guide surface 24. By this pull-out operation, the pin 5 can be pulled out with a small force until the pin 5 comes into contact with the retaining portion 23 (FIGS. 3B and 5B).

At this time, the lid 2b opens the plug insertion opening by elastic deformation of the tongue piece 2c so that the plug can be easily inserted into the terminal from the outside (FIG. 5c).

In this state, the pin 5 is
It stops at 3 and prevents it from falling out.

Therefore, it is possible to provide a terminal cover which can be pulled out to open the lid with a simple structure.

When the user does not need the terminal cover 2 and wants to remove the terminal cover 2 from the main body, a further force in the pulling direction is applied from the state where the pin 5 is in contact with the retaining portion 23. Deviate. This will be described with reference to FIG.

FIG. 4 is a view for explaining a situation in which the pin 5 comes off from the state in which the pin 5 is in contact with the retaining portion 23.

FIG. 3A shows a state in which the pin 5 is in contact with the retaining portion 23. FIG. 2B shows a case where a larger force than usual is applied to further pull out the terminal cover 2. As a result, the retaining portion 23 is pressed, and the inclined surface 22 and the distal end surface 21 are deformed (b in the drawing).

Thereafter, when the force is further applied, the deformation of the inclined surface 22 and the distal end surface 21 becomes maximum, and the pin 5 moves close to the inclined surface 22 so that the terminal cover 2 is separated from the main body. Figure c).

That is, when the terminal cover 2 is used with the lid open and closed, the lid is opened and closed with a weak force, and the terminal cover 2 can be easily removed by applying a little force only when the terminal cover 2 is removed. Can be provided.

Further, by providing the notch 21a in the distal end surface 21 as shown in FIG. 6, elastic deformation of the distal end surface 21 in the state of FIG. 4B can be promoted. Therefore, it can be removed more smoothly at the time of removal. Also,
Since the elastic deformation can be adjusted by the number and depth of the notches, the number and depth can be adjusted according to the material of the terminal cover.

[0034]

As described above, according to the present invention,
It is possible to provide a device that can be easily attached, can easily open and close the lid even after being attached, and can be easily removed.

In other words, it is better to remove the terminal cover when the plug is repeatedly inserted and removed. Therefore, if this terminal cover is used, it can be easily removed by elastic deformation. Then, when it is no longer necessary to remove it, it can be easily attached by utilizing its elastic deformation.

Further, the plug can be easily inserted into the terminal even after the attachment. The terminal cover is the guide part 24
Thereby, it is smoothly pulled out to the retaining portion 23. With a predetermined pulling-out force, it stops at the retaining portion 23, and further pulling-out, that is, the terminal cover does not come off the main body.

However, when the user wants to remove the terminal cover, if the user pulls out the terminal cover with a predetermined pulling force or more, the retaining portion is elastically deformed outward. As a result, the pin 5 comes off from the retaining portion, and the terminal cover comes off from the main body, so that the cover can be opened and closed and the cover can be attached and detached with a simple configuration.
