Description

  The present invention relates to a mobile terminal including a terminal cover that covers a charging terminal, a card terminal, a headphone terminal, and the like.

  2. Description of the Related Art Conventionally, mobile terminals, particularly mobile phones, have been equipped with many terminals such as a charging terminal, a card terminal, a headphone terminal, and the like as the functionality is improved. Each terminal is protected from dust by being configured to be freely opened and closed by a terminal cover.

  For example, in Patent Document 1, in the external connection terminal portion of the portable terminal, when the terminal cover is attached, the inclined surface comes into contact with the boss in the main body, and when the terminal cover is pushed in, the boss is prevented from coming off due to the deformation of the elastic deformation hole. By being located in the part for use, it is prevented from coming off. When opening the terminal cover, the boss is pulled out along the guide surface. When removing the terminal cover, the retaining portion, the inclined surface, and the tip surface are elastically deformed so that they can be easily removed. As a result, the terminal cover can be easily removed without being broken or lost during use.

Moreover, in the external connection terminal cover structure of the portable terminal of patent document 2, a mechanism (a pair of controls) that restricts the movement of the elastic terminal member that holds the cover member for covering the external connection terminal portion in the housing in the housing insertion / extraction direction. In addition to the claw and the boss that engages the claw, a mechanism (third claw, stopper, and arm) that restricts movement in the direction substantially perpendicular to the insertion / extraction direction is added. Elastic deformation is prevented.

  However, in the above Patent Documents 1 and 2, since the thickness of the terminal cover retaining portion is thin, the effect of preventing the terminal cover from coming off is not sufficient. For this reason, if the terminal cover is unintentionally removed, it may not be noticed that it has been dropped and lost without sound.

  This invention is made | formed in view of this point, The place made into the objective is to obtain the terminal cover for portable terminals which is hard to remove and is easy to insert.

  In order to achieve the above object, in the present invention, a claw portion, a connecting portion deforming hole, and a bridging portion are provided in a connecting portion connected to the lid portion of the terminal cover.

Specifically, in the first invention, a portable terminal including a terminal cover that closes a terminal opening for exposing a connection terminal is targeted.
The mobile device
The periphery of the terminal opening is surrounded by a terminal recess recessed from the periphery, and a locking hole is formed in the terminal recess,
The terminal cover includes a lid that closes the terminal recess, and a connecting portion that is substantially orthogonal to the lid.
The connecting part is
A claw portion inserted into and engaged with the locking hole;
A connecting portion deformation hole formed between the claw portion and the lid portion to help the deformation of the connecting portion;
A bridging portion that is formed in the coupling portion deformation hole, and bridges between the coupling portion deformation hole periphery and the claw portion;
The claw portion is inclined in a direction away from the connecting portion toward the lid portion,
The bridge section above
An inclined portion that is connected to an end of the claw portion on the lid portion side and is inclined in a direction approaching the connecting portion toward the lid portion;
And a horizontal portion connected to the inclined portion.

  According to the above configuration, when the coupling portion is inserted into the locking hole, the claw portion abuts on the peripheral edge of the locking hole and is pressed toward the inclined portion side, and the force is smoothly transferred from the inclined portion to the horizontal portion. Since it is transmitted, the terminal cover can be easily inserted. When the claw portion is pulled, the claw portion is not easily turned up by the bridging portion that bridges between the claw portion and the peripheral edge of the connecting portion deformation hole, so that the terminal cover does not come out unintentionally.

In the second invention, in the first invention,
Between the bridging portion and the lid portion at the periphery of the coupling portion deforming hole, a bridging portion deforming hole that facilitates deformation of the bridging portion is formed.

  According to the above configuration, when the terminal cover is inserted, the claw portion comes into contact with the peripheral edge of the locking hole and is pressed downward, but the force is transmitted from the inclined portion to the horizontal portion, and the bridge portion is deformed. Due to the deformation of the hole, the bridge portion is easily inserted into the locking hole.

In the third invention, in the second invention,
At the distal end of the connecting portion, a flange portion is formed which expands as it approaches the lid portion and becomes wider than the locking hole, and again becomes narrower than the locking hole,
In the connecting portion, a projection portion narrower than the width of the hook portion and wider than the width of the locking hole is formed on the lid portion side of the hook portion.

  According to the above configuration, when the terminal cover is pulled out and opened by providing a difference in width between the collar and the protrusion, it is easy to allow the protrusion to pass through the locking hole, and the terminal cover can be easily opened. However, by making it difficult to pass through the buttock, it is difficult to remove the terminal cover to prevent the terminal cover from being lost.

In a fourth invention, in any one of the first to third inventions,
The terminal cover is made of an elastic member.

  According to said structure, since a terminal cover is elastically deformed easily, it becomes easy to insert and becomes durable.

  As described above, according to the terminal cover of the present invention, the claw portion that is provided with the lid portion that closes the concave portion for the terminal, is connected to the lid portion substantially orthogonally, and is inserted into the locking hole and engaged. And providing a connecting part having a connecting part deformation hole formed between the claw part and the lid part to assist deformation, and a bridging part that bridges between the peripheral part of the connecting part deformation hole and the claw part, A terminal cover that is difficult to remove and easy to insert is obtained.

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

  The second housing 5 contains a rechargeable battery 9 (shown only in FIG. 6). A charging terminal 7 as a connection terminal for charging the rechargeable battery 9 is built in the lower end portion of the second housing 5. As shown in FIG. 4, the charging terminal 7 is exposed from a rectangular terminal opening 8 extending in the left-right direction. A charging terminal (not shown) is connected to the charging terminal 7 to allow charging. The terminal opening 8 is covered with a terminal cover 10 so as to be openable and closable for the purpose of dust-proofing, waterproofing and improving the appearance.

  The periphery of the terminal opening 8 is surrounded by a rectangular terminal recess 11 that is recessed from the periphery. A linear locking hole 12 extending in the left-right direction is opened below the terminal opening 8 in the terminal recess 11.

  As shown in FIG. 5, the terminal cover 10 includes a rectangular plate-like lid portion 13 that closes the terminal recess 11. The terminal cover 10 is made of an elastic member such as synthetic resin or elastomer. A connecting portion 14 that is substantially orthogonal to the lid portion 13 is provided at a portion of the lid portion 13 corresponding to the locking hole 12.

  The connecting portion 14 includes a claw portion 15 that is inserted into the locking hole 12 at the tip end opposite to the lid portion 13 and is engaged with the locking hole 12. The claw portion 15 has a flat claw portion main body 15a inclined in a direction away from the connecting portion 14 toward the lid portion 13, and a pair of side walls 15b having a triangular shape in side view, which connects the claw portion main body 15a to the connecting portion 14. It is equipped with. The connecting portion 14 is thinner than the lid 13 and is easily deformed.

  Between the nail | claw part 15 and the cover part 13, the connection part deformation | transformation hole 17 long to the left and right which helps the deformation | transformation of the connection part 14 is formed.

  A bridging portion 18 that bridges between the peripheral edge of the connecting portion deforming hole 17 and the claw portion 15 is formed at the left and right center of the connecting portion deforming hole 17. The bridging portion 18 includes an inclined portion 18 a that is connected to the end portion of the claw portion 15 on the lid portion 13 side and is inclined toward the lid portion 13 toward the connecting portion 14. The inclined portion 18 a is connected to a horizontal portion 18 b that extends horizontally, and the other end of the horizontal portion 18 b is connected to the periphery of the connecting portion deformation hole 17. The horizontal portion 18 b is disposed on the same plane as the connecting portion 14.

  As shown in FIG. 6, the height h1 of the claw portion 15 is higher than the height h2 of the locking hole 12 (h1> h2). For this reason, when the claw portion 15 passes through the locking hole 12, it always comes into contact with the peripheral edge of the locking hole 12.

  A bridging portion deforming hole 19 is formed in front of the lid portion 13 on the extension of the horizontal portion 18 b of the bridging portion 18 at the periphery of the connecting portion deforming hole 17. The bridging portion deforming hole 19 has an oval shape extending to the left and right, and plays a role of facilitating deformation of the bridging portion 18.

  As shown in FIG. 7, a flange portion 20 is formed at the distal end of the connecting portion 14 so as to increase in width as it approaches the lid portion 13 and narrow again. The maximum width W1 of the flange 20 is larger than the width W2 of the locking hole (W1> W2). A notch 21 is formed on the lid portion 13 side of the collar portion 20, and the collar portion 20 is easily deformed when passing through the locking hole 12. The width of the flange portion 20 on the lid portion 13 side is narrower than the width W2 of the locking hole 12, and the width W3 of the projection portion 22 that protrudes in the left-right direction again is larger than the width W2 of the locking hole 12. (W3> W1). Further, the width W3 of the protrusion 22 is narrower than the width W1 of the flange 20 (W3> W2> W1).

-Action of mobile phone-
Next, the operation of the mobile terminal according to the present embodiment will be described.

  As shown in FIGS. 6A and 7A, before the terminal cover 10 is inserted into the locking hole 12, the height h1 of the claw portion 15 is higher than the height h2 of the locking hole 12. The maximum width W1 of the flange portion 20 is larger than the width W2 of the locking hole.

  For this reason, as shown in FIG. 6B and FIG. 7B, when the claw portion 15 and the flange portion 20 pass through the locking hole 12, they come into contact with the peripheral edge of the locking hole 12.

  When the terminal cover 10 is further inserted, as shown in FIGS. 5 and 8A, the claw portion 15 in contact with the locking hole 12 is deformed to push up the inclined portion 18a. This force is transmitted to the horizontal portion 18b as shown by the white arrow, and deforms the bridge portion deformation hole 19. At the same time, the flange portion 20 comes into contact with the locking hole 12 and is deformed toward the notch 21, and the connecting portion deformation hole 17 is deformed. For this reason, insertion of the terminal cover 10 becomes easy.

  As shown in FIG. 8B, when the collar part 20 passes through the locking hole 12, the connecting part 14 returns to its original shape because it has elasticity, and the collar part 20 is caught in the locking hole 12. Therefore, if the connecting portion 14 is bent in this state, the terminal cover 10 can be charged without being removed. The terminal cover 10 is difficult to be removed by the burr portion of the collar portion 20. Furthermore, since the claw portion 15 is not easily turned up by the bridge portion 18 and the side wall 15b even if the claw portion 15 is pulled, the terminal cover 10 is more difficult to be removed.

  Further, when the terminal cover 10 is inserted, the protrusion 22 is deformed while coming into contact with the peripheral edge of the locking hole 12, and as shown in FIG. 7C, the surface of the lid 13 and the periphery of the terminal recess 11 Becomes a substantially continuous closed state.

  In this way, the terminal cover 10 made of an elastic member is easily elastically deformed, so that it can be easily inserted. Then, by making the width W3 of the protrusion 22 smaller than the width W1 of the flange 20, it is easy to allow the protrusion 22 to pass through the locking hole 12 when the terminal cover 10 is pulled out and opened. By making the terminal cover 10 easy to open and making it difficult to pass the collar part 20, it is difficult to remove the terminal cover 10 to prevent the terminal cover 10 from being lost.

-Effect of the embodiment-
Therefore, according to the mobile phone 1 according to the present embodiment, the terminal cover 10 is provided with the lid portion 13 that closes the terminal recess 11, and is further substantially orthogonal to the lid portion 13 and inserted into the locking hole 12. The claw portion 15 engaged with each other, the connecting portion deformation hole 17 formed between the claw portion 15 and the lid portion 13 to assist deformation, and the periphery of the connecting portion deformation hole 17 and the claw portion 15 are bridged. By providing the connecting portion 14 having the bridging portion 18, a terminal cover that is difficult to be removed and easy to insert can be obtained.
