  However, when the thing of the said patent document 2 is applied as a cover for the external connection terminal of a portable terminal, the whole cover protrudes from the surface of a portable terminal main body, and when a portable terminal is handled, a cover becomes obstructive and portability is impaired. There is a problem that the design is impaired.

  Further, in the case of the above-mentioned Patent Document 3, there is a trouble of avoiding the cover itself from the insertion route of the external connection terminal when inserting the external connection terminal, and the avoided cover protrudes from the mobile terminal main body so that the mobile terminal is There is a problem that the portability is impaired when handling the cover and the portability is impaired.

  The present invention has been made in view of the above points, and the object of the present invention is to prevent the user from losing the jack cover and to prevent the jack cover from being obstructed and to deteriorate the portability. It is to prevent damage.

  In order to achieve the above object, in the present invention, the removed jack cover can be attached to and detached from the dummy jack.

Specifically, on the premise of a portable terminal having a built-in portable terminal body into which a jack into which an external connection terminal is inserted, and a jack cover detachably attached to the jack,
The jack includes a contact spring portion that protrudes from the inner surface of the jack and is brought into pressure contact with the external connection terminal when the external connection terminal is inserted into the jack.
The jack cover includes a avoiding recess for avoiding the contact spring portion when inserted into the jack,
A dummy jack that can attach and detach the jack cover is provided at a position different from the jack of the mobile terminal body,
The dummy jack includes a protrusion that fits in the avoidance recess when the jack cover is inserted and abuts against the external connection terminal when the external connection terminal is inserted to prevent insertion of the external connection terminal. Yes.

  According to the above configuration, when the external connection terminal is inserted, the contact spring portion acting as an electrical contact projecting on the inner surface of the jack is bent to be electrically connected to the external connection terminal. Since the concave portion is provided, when the jack is covered with the jack cover, the contact spring portion can be protected in dimension and the contact spring portion can be protected. Furthermore, since the recess avoids the protrusion of the dummy jack, the jack cover is easily fitted into the dummy jack. On the other hand, even if the external connection terminal is erroneously inserted into the dummy jack, the protrusion of the dummy jack abuts against the external connection terminal and prevents its entry, so that the user can be informed of the erroneous insertion. And, when the external connection terminal is inserted into the jack, the user can prevent the jack cover from being lost by fitting the removed jack cover into the dummy jack, and the jack cover fits into the dummy jack. That is why portability is not impaired. On the other hand, since the jack cover inserted into the jack when the external connection terminal is not used is fitted in a position different from the jack in the portable terminal body, the appearance is not impaired. Especially when the design of the jack cover is unique, you can enjoy the design and color as fashion.

In the second invention, in the first invention,
The dummy jack is made of a resin molded product.
The protrusion is integrally formed with the dummy jack.

  According to the above configuration, since the protrusion is easy to form and is a resin molded product, it is more rigid than the contact spring part, has a high effect of preventing the insertion of the external connection terminal, and is too hard to externally connect. The terminal is not damaged.

  As described above, according to the present invention, a dummy jack to which the jack cover can be attached and detached is provided at a position different from the jack of the mobile terminal body, a protrusion is provided on the dummy jack, and the jack cover is inserted into the protrusion. Sometimes it fits in the recess for avoidance and prevents the user from losing the jack cover by abutting against the external connection terminal when inserting the external connection terminal to prevent the insertion of the external connection terminal. It is possible to prevent the jack cover from interfering with the portability and the appearance.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show a mobile phone 1 as a mobile terminal according to an embodiment of the present invention. The mobile phone 1 includes a mobile phone body 2 as a mobile terminal body having a rectangular plate shape. The mobile phone body 2 is configured by assembling a cabinet or the like made of a resin molded product, for example, and has a built-in jack 3 (see FIG. 3) into which an external connection terminal 5 made of an earphone plug or the like is inserted. A dummy jack 4 is also incorporated on the right side of the jack 3 when viewed from the front in the mobile phone body 2. When the external connection terminal 5 is not used, the jack 3 is covered with a jack cover 6 made of, for example, a resin molded product, as shown in FIG.

  As shown in FIGS. 3 to 5, the jack 3 includes, for example, a main body of a resin molded product, and is fitted and fixed to the mobile phone main body 2. At the center of the jack 3, a bottomed hole portion 3a is opened, and a plurality of contact spring portions 3b, 3c, 3d projecting radially inward from the inner surface forming the hole portion 3a are incorporated. The contact spring portions 3b, 3c, 3d are made of conductive leaf springs and are connected to an internal substrate (not shown). The jack 3 is arranged in the mobile phone body 2 so that the hole 3 a is opened above the mobile phone body 2.

  On the other hand, as shown in FIG. 5, the external connection terminal 5 is provided with a rod-like insertion portion 5a to be inserted into the hole 3a. When the insertion portion 5a is inserted into the hole portion 3a, each contact spring portion 3b, 3c, 3d is pushed and bent outwardly in the radial direction of the hole portion 3a by the insertion portion 5a. The spring portions 3b, 3c, 3d are electrically connected.

  As shown in FIGS. 6 to 8, the dummy jack 4 is made of a resin molded product like the jack 3 and is fixed to the mobile phone body 2 by fitting or the like. The dummy jack 4 is provided with a dummy hole 4 a having substantially the same size as the hole 3 a in the jack 3. And the protrusion 4b which protrudes to a radial inside so that it may extend along the insertion direction of the insertion part 5a in the position corresponding to the contact spring part 3b of the jack 3 is integrally molded by the inner surface of the dummy hole part 4a. . Since the protrusion 4b can be formed integrally, the dummy jack 4 can be formed easily. The dummy jack 4 is disposed in the mobile phone body 2 so that the dummy hole 4 a is opened above the mobile phone body 2. When the insertion portion 5a of the external connection terminal 5 is to be inserted into the dummy hole portion 4a, the protrusion 4b has a dimensional relationship that prevents the insertion portion 5a from being inserted without bending like the contact spring portion 3b.

  As shown in FIGS. 9 and 10, the jack cover 6 is provided with cover pins 6 a having substantially the same outer shape as the insertion portion 5 a in the external connection terminal 5. On the outer periphery of the cover pin 6a, avoidance concave grooves 6b, 6c, 6d extending in the longitudinal direction are formed at positions corresponding to the contact spring portions 3b, 3c, 3d, and interference with the contact spring portions 3b, 3c, 3d. Each can be avoided. A curved plate-like cover main body 6e is integrally formed on the base end side of the cover pin 6a, and when the cover main body 6e covers the jack 3 or the dummy jack 4 with the jack cover 6, it appears in the appearance. Yes. Since the cover body 6e has a partially curved shape along the outer surface of the mobile phone body 2, the cover body 6e may not be conspicuous as the same color tone as the mobile phone body 2, or may be conspicuous as a different color tone. You may do it. By making the jack cover 6 a resin molded product having high wear resistance, for example, the jack cover 6 can be prevented from being worn or scraped.

  Next, the operation of the mobile phone 1 according to this embodiment will be described.

  First, when the external connection terminal 5 is not used, as shown in FIG. 2, the jack cover 6 covers the hole 3a of the jack 3, and the dummy hole 4a is not covered. Since the avoiding concave grooves 6b, 6c, 6d are formed on the outer periphery of the cover pin 6a, interference between the cover pin 6a and the contact spring portions 3b, 3c, 3d is avoided. Further, since the hole 3a is covered with the jack cover 6 to be dust-proof, there is no adverse effect due to dust such as poor contact of the contact spring portions 3b, 3c, 3d. On the other hand, unlike the jack 3, the dummy jack 4 does not include the contact spring portions 3b, 3c, and 3d. Therefore, when the external connection terminal 5 is not used, the dummy jack 4 is not covered with the jack cover 6 and some dust is generated in the dummy hole portion 4a. There is no problem even if you get in. Furthermore, since the cover body 6e has a shape along the outer surface of the mobile phone body 2, it does not protrude greatly from the surface of the mobile phone body 2, so that the portability is not impaired and the design is not impaired.

  Next, when the external connection terminal 5 is used, the jack cover 6 is first removed from the jack 3. Also at this time, since the avoidance concave grooves 6b, 6c and 6d are formed on the outer periphery of the cover pin 6a, the cover pin 6a and the contact spring portions 3b, 3c and 3d do not come into contact with each other, and the contact spring portions 3b and 3c. , 3d is prevented. Here, if the user tries to insert the external connection terminal 5 into the dummy jack 4 as shown in FIG. 8, the insertion portion 5a is in contact with the projection 4b and cannot be inserted. Can be recognized. At this time, since the protrusion 4b is made of resin instead of a leaf spring, it does not bend like the contact spring portions 3b, 3c, 3d, and it is too hard to damage the insertion portion 5a. .

  Next, the jack cover 6 is fitted into the dummy jack 4. A protrusion 4b is provided on the inner surface of the dummy hole 4a, and this protrusion 4b can be fitted into the avoidance concave groove 6b on the outer periphery of the cover pin 6a, so that the jack cover 6 is firmly in place. Fixed to. For this reason, losing the jack cover 6 is prevented. Since the cover body 6e has a shape along the outer surface of the mobile phone body 2 as when the jack 3 is covered, the cover body 6e does not protrude greatly from the surface of the mobile phone body 2 and the portability is impaired. There is no loss of design. And as shown in FIG. 1, the insertion part 5a is inserted in the hole 3a.

  On the other hand, in the conventional example shown in FIG. 12 and FIG. 13, since the dummy jack 4 is not provided, when the jack cover 6 is removed as shown in FIG. 13 from when the external connection terminal 5 of FIG. 12 is not used. There is no place to store the jack cover 6 and the jack cover 6 is easily lost.

  Therefore, according to the present embodiment, it is possible to prevent the user from losing the jack cover 6 and to prevent the jack cover 6 from interfering with the portability and the appearance.
