Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable terminal such as a cellular phone or a portable information terminal. In particular, the present invention relates to a mobile terminal characterized by a terminal cover structure used to cover a terminal for data communication of the mobile terminal.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, mobile terminals are provided with external connection terminals such as communication I / O connectors, and a terminal cover is fitted and closed to prevent entry of dust and the like.
[0003]
This terminal cover is made of a molded product such as resin, and it is made of a removable terminal cover that can be removed from the main body, or an elastic member such as rubber, and one end is held by the main body so as not to be detached from the main body. There is a main body holding type terminal cover that can release the closed state of the terminal by rotating and opening the other end.
[0004]
The removable terminal cover that is removed from one body is a terminal cover with a structure that can be fitted with the unevenness of the structure of the terminal, and it can be easily removed, so it will be removed carelessly, The problem is that it is easy to lose.
[0005]
In order to prevent this, a main body holding type terminal cover may be used.
[0006]
However, with this body-holding type terminal cover, it may be necessary to open (remove the cover) many times in order to connect the plug frequently at the factory setting, or when the user frequently communicates Similarly, since it is necessary to open the terminal cover many times, it was troublesome to open the terminal cover.
[0007]
In addition, when the plug is used in such a large amount, the terminal cover of the main body holding type is opened and closed many times, so that it may “break” from the vicinity of the fulcrum due to deterioration.
[0008]
This conventional example will be described with reference to FIG. This figure shows an external connection terminal (not shown) of a mobile terminal (here, a mobile phone) and a plug connected thereto. A plug insertion slot 3 is provided at one end of the terminal 1, and an external connection terminal (not shown) is provided in the plug insertion slot 3 so that the terminal cover 20 covers the insertion slot 3.
[0009]
The plug terminal 4a of the plug 4 is connected to the external connection terminal of the portable terminal 1 through the plug insertion port 3 with the terminal cover 20 opened.
[0010]
FIG. 8 shows a configuration of a conventional terminal cover 20. The terminal cover 20 has a recess 20a for hooking and opening a finger, a lid portion 20b for covering the terminal, a tongue piece portion 20c for connecting the lid portion 20b to the main body, and a screw or boss to the terminal 1 main body. And a hole 20d for fixing with a single body, and made of an elastic member (for example, rubber).
[0011]
For example, when the front surface 1a and the rear surface 1b of the main body 1 are combined, the terminal cover 20 is attached to the main body 1 through the hole 20d. Thus, if it attaches to a main body, unless the front surface 1a and the rear surface 1b are removed, the terminal cover 20 has a structure which cannot be removed. In addition, if a force is applied in the vicinity of the fulcrum shaft 20e by opening and closing the lid portion 20b, and it is repeated, it may be considered that the fulcrum shaft 20e is broken.
[0012]
[Problems to be solved by the invention]
In view of the problem of the structure of the external connection terminal portion of the conventional portable terminal as described above, the object of the present invention is that the terminal cover is not broken or lost during use, and can be easily removed. A terminal cover is obtained.
[0013]
[Means for solving the problems]
The present invention relates to a portable terminal provided with a terminal for external connection, an elastic deformation portion that elastically deforms when attached to the main body, and a disconnection that prevents removal until a force greater than a predetermined force is applied when removing from the main body. A terminal cover that covers the external connection terminal including a stopper, and elastically deforming means that is provided on the main body side, elastically deforms the terminal cover, and engages with the retaining part. The terminal cover can be opened and closed so that the terminal for external connection can be used in a state where the terminal is removed from the main body, and the terminal for external connection can be used without removing the terminal cover from the main body.
Further, the present invention provides a portable terminal including a terminal for external connection, wherein the external device includes a first elastic deformation portion that elastically deforms when attached to the main body and a second elastic deformation portion that elastically deforms when detached. A terminal cover that covers the connection terminal and an elastically deformable means that is provided on the main body side and causes the elastic deformation of the terminal cover.
[0014]
The terminal cover includes a lid that covers the terminal for external connection and a tongue piece attached to the main body, and the first elastic deformation portion and the second elastic deformation portion are attached to the tongue piece portion. It is characterized by providing.
[0015]
Furthermore, the tongue piece is elastically deformed when the terminal for external connection is used.
[0016]
Further, the first elastic deformation portion is characterized by comprising elastic deformation means in which at least the tongue piece portion is cut out in a hole shape.
[0017]
[Embodiment]
FIG. 1 is a view showing a terminal cover. The terminal cover 2 includes a concave portion 2a for hooking a finger or the like to open, a lid portion 2b for covering the terminal, and a tongue piece portion 2c for connecting the lid portion 2b to the main body. Furthermore, the front end surface 21 of the tongue piece 2c, the inclined surface 22 to which the boss 5 of the main body abuts when being mounted, and a retaining portion 23 which is not easily removed after being mounted on the main body, When the boss of the main body guides the tongue piece 2c when opening and closing, thereby guiding the whole terminal cover 2 and elastically deforming when the terminal cover 2 is attached to the main body 1, a small force after the attachment Then, the elastic deformation hole 25 to prevent the elastic deformation and the terminal guide portion 27 that functions as a guide to the terminal of the main body are integrated, and is made of an elastic member (for example, rubber).
[0018]
And the plug insertion port 3 of the main body 1 between the front surface 1a and the rear surface 1b is closed.
[0019]
FIG. 2 is a partial cross-sectional view showing a state transition in which the terminal cover 2 is fitted to the main body 1, and a hatched portion (upper side in the figure) is a portion covered with the main body 1. Two pins 5 are integrated with either the front surface 1 a or the rear surface 1 b of the main body 1.
[0020]
The figure a is a figure which shows the state which is going to fit from now on in the state which the terminal cover 2 removed. Then, when the state proceeds to the fitting, the body-side pin 5 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 figure). Further proceeding, the pin 5 moves over the inclined surface 22 and moves to the vicinity of the retaining portion 23 and the pressing force holding the inclined surface 22 disappears, so that the inclined surface 22 returns to its original position and deforms. The elastic deformation hole 25 that has been restored also returns to its original shape (FIG. 3c).
[0021]
Thereby, the fitting of the terminal cover 2 to the main body is completed. Since elastic deformation by a resin such as rubber is used, the terminal cover can be easily fitted to the main body without requiring a large force.
[0022]
FIG. 3 is a view showing a state in which the terminal cover is opened and closed.
[0023]
FIG. 5A shows the terminal cover 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 flush with the surface of the main body 1, and the terminal cover 2 is integrated with the main body 1 without a sense of incongruity (FIG. 5a).
[0024]
Next, in order to remove the terminal cover, the user hooks a finger, a nail or the like on the recess 2a, and opens the lid 2b. Then, it is guided to be pulled out straight by the pin 5 in contact with the guide surface 24. By this pulling-out operation, the pin 5 can be pulled out with a small force until it comes into contact with the retaining portion 23 (FIGS. 3b and 5b).
[0025]
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).
[0026]
In this state, the pin 5 stops at the retaining portion 23 to prevent it from coming off.
[0027]
Accordingly, it is possible to provide a terminal cover that can be pulled out for opening the lid with a simple configuration.
[0028]
Further, when the user does not need the terminal cover 2 and wants to remove it from the main body, the user can remove the terminal cover 2 by applying a force in the pulling direction from the state in which the pin 5 is in contact with the retaining portion 23. This will be described with reference to FIG.
[0029]
FIG. 4 is a diagram for explaining a situation in which the pin 5 comes out of contact with the retaining portion 23.
[0030]
FIG. 6A shows a state where the pin 5 is in contact with the retaining portion 23. FIG. 5B shows a case where a force larger than usual is applied to further pull out the terminal cover 2. As a result, the retaining portion 23 is pushed, and the inclined surface 22 and the tip surface 21 are deformed (b in FIG. 4).
[0031]
Thereafter, when the force is further applied, the deformation of the inclined surface 22 and the tip surface 21 becomes maximum, and the pin 5 moves to the side of the inclined surface 22 so that the terminal cover 2 is separated from the main body (FIG. 3c). .
[0032]
In other words, when using the terminal cover 2 with the terminal cover 2 open and closed, the cover is opened and closed with a weak force, and a structure that can be easily removed by applying a little force only when removing the terminal cover 2 is provided. be able to.
[0033]
Further, by providing the notch 21a on the tip surface 21 as shown in FIG. 6, it is possible to promote elastic deformation of the tip surface 21 in the state of FIG. 4b. Therefore, it can be removed more smoothly during removal. Further, since the elastic deformation can be adjusted by the number and depth of the notches, it is also possible to adjust the number and depth according to the material of the terminal cover.
[0034]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a device that can be easily attached and can be easily opened and closed even after being attached and can be easily removed.
[0035]
That is, it is better to remove the terminal cover when the plug is inserted and removed many times. Therefore, when this terminal cover is used, it can be easily removed by elastic deformation. And when it is no longer necessary to remove it, it can be easily attached using its elastic deformation.
[0036]
In addition, the plug can be easily inserted into the terminal even after installation. The terminal cover is smoothly pulled out to the retaining portion 23 by the guide portion 24. With a predetermined pulling-out force, it stops at the retaining portion 23 and no further pulling out, that is, the terminal cover does not come off from the main body.
[0037]
However, when the user wants to remove the terminal cover, when 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 is removed from the retaining portion and the terminal cover is detached from the main body, and the cover can be opened and closed and the cover can be attached and detached with a simple configuration.
