  The present invention relates to a structure for attaching a terminal cover to an electronic device. In particular, the present invention relates to a structure for attaching a cover to an electronic device and a mobile phone that can simplify the structure and improve the productivity of parts and the handling of a terminal cover.

FIG. 4 is a perspective view showing a schematic appearance of a mobile phone as a premise of the present invention, and FIG. 5 is a view showing a state where an external connection connector is connected to the mobile phone of FIG. In addition, the same number and code | symbol are attached | subjected to the same component through all the figures.
A mobile phone will be described as an example of an electronic device. As shown in FIG. 4, for example, the mobile phone is a foldable type, the lower case 100 of the foldable type mobile phone is provided with a key operation unit 100 </ b> A, and the external connection terminal 111 is provided on the side surface of the lower case 100. A terminal cover 112 is attached to the external connection terminal 111.

As shown in FIG. 5, the terminal cover 112 attached to the external connection terminal 111 is an elastomer resin molded product, can be opened and closed, and can be folded back using an attachment portion 112 </ b> C described later as a fulcrum.
An external connection connector 201 is connected to the external connection terminal 111. When the external connection connector 201 is connected to the external connection terminal 111, the terminal cover 112 is opened, the cover of the external connection terminal 111 is released, and the external connection connector 201 is externally connected. After disconnecting from the terminal 111, the terminal cover 112 is closed, and the external connection terminal 111 is covered to provide dust protection.

FIG. 6 is a perspective view showing a schematic appearance of the structure of the terminal cover 112 of FIG. As shown in the figure, the terminal cover 112 is provided with a plurality of fitting claws 112A, and the fitting claws 112A are engaged with the external connection terminal 111 and released from fitting by the force applied to the terminal cover 112. .
Further, the terminal cover 112 is provided with a plurality of ribs 112B, and the ribs 112B reinforce the strength of the terminal cover 112 against the force applied during opening and closing.

However, since the terminal cover 112 is an elastomer resin molded product, if the shape of the terminal cover 112 is uneven, gas is generated during molding, resulting in deterioration of appearance quality and component shape, resulting in poor yield. There was one problem.
Furthermore, there is a second problem that the rib 112B is crushed when the terminal cover 112 is opened and closed, and a problem that the fitting cannot be performed occurs.

Further, when the terminal cover 112 is opened to connect the external connection connector 201 and the external connection connector 201 is connected to the external connection terminal 111, the terminal cover 112 protrudes and is in an unstable state. There was a third problem of being damaged by being caught. For such a problem, there is a problem that the mounting structure of the terminal cover 112 should be simplified to improve the productivity of parts and the handleability of the terminal cover.
In relation to such problems, there are the following conventional techniques.

  Conventionally, in order to make it easy to attach and detach the cap attached to the housing, the fitting recess provided in a concave shape on the lower housing and the inside of the fitting recess exposing the connection terminal for electrical connection with the outside And a cap provided in a fitting recess in the vicinity of the terminal port to detachably fit the flexible cap into the fitting recess and close the terminal port with the cap. The cap has an engaging projection of a shape that can be attached to and detached from the mounting port, and the engaging projection changes to the mounting port while the engaging projection itself changes. Some have gaps for attaching and detaching (see, for example, Patent Document 1).

However, in the above-mentioned Patent Document 1, there is a mobile phone in which a flexible cap is detachably fitted in a fitting recess and the terminal port is closed by the cap so that the terminal can be opened and closed. It does not solve the problems such as yield, collapse of the rib structure, and damage.
Conventionally, by using a metal endless belt, the noise is reduced, the conveyance speed is improved, the contamination of the connection portion is prevented from becoming unsanitary, and the circumferential accuracy of the endless belt and the pulley In order to prevent the endless belt from shifting due to parallelism, a resin cover is attached to a metal endless belt, and a first magnet is embedded in the resin cover. A second magnet is installed to prevent belt slippage by the magnet's attractive force, and a mechanism for adjusting the angle of the spindle of the pulley is provided to adjust the parallelism of the pulley prior to driving operation ( For example, see Patent Document 2).

However, in Patent Document 2, the first magnet is embedded in the resin cover, and on the other hand, the second magnet is attached to the frame that is in contact with and supported by the lower surface of the endless belt, thereby preventing the belt from being displaced by the magnet's adsorption force. However, as described above, it does not solve the problems of the yield, the collapse of the rib structure, and the damage caused by the elastomer resin with respect to the terminal cover.
Further, conventionally, the main body, the folding cover that covers at least the switch portion of the main body, the first magnet provided in the main body, and the first magnet provided in the cover that attract each other when the cover is closed. An uneven portion provided on the main body and the cover, provided with a second magnet and a release button that is provided on the main body and moves the first magnet to a position that weakens the attractive force with the second magnet when the cover is opened. In addition to providing a one-touch locking mechanism that does not require the user to open the cover by hand, there are those that are excellent in dust resistance and waterproofing and that do not cause mechanical damage (for example, patents) Reference 3).

However, in the above-mentioned Patent Document 3, there is one in which a first magnet provided in the main body and a second magnet provided in the cover and attracting the first magnet when the cover is closed are provided. As described above, it does not solve the problems of the yield, the collapse of the rib structure, and the damage caused by the elastomer resin with respect to the terminal cover.
Conventionally, an IF connector (connector) is provided at one end of the lower case (case body) in order to protect the corner of the case body, which is a portion that is easily damaged when dropped, without increasing the number of parts. In addition, a protective member made of an elastomer is provided at one end of the side where the connector is provided and a corner thereof, and the protective member can be fitted into the connector. There is one in which a connector cover (connector cover) is integrally formed (see, for example, Patent Document 4).

  However, in the above-mentioned Patent Document 4, a protective cover made of an elastomer is provided at one end of the side where the connector is provided and a corner thereof, and a connector cover ( The connector cover is integrally formed. However, as described above, it does not solve the problem of yield due to the elastomer resin, collapse of the rib structure, and damage to the terminal cover.

  Conventionally, in order to facilitate the attachment of the terminal block body and the terminal cover, the terminal block body to which a plurality of terminal screws are attached and the terminal cover that covers the upper surface of the terminal block body are respectively magnetized after resin molding. The terminal block main body is attached by magnetic attraction on a mounting plate made of a magnetic material, and the terminal cover is attached to the upper surface of the terminal block main body by magnetic attraction (for example, Patent Document 5). reference).

However, in Patent Document 5, the terminal cover is attached to the upper surface of the terminal block main body by magnetic attraction. As described above, the yield is due to the elastomer resin, and the rib structure is crushed or damaged with respect to the terminal cover. It does not solve the problem.
Conventionally, an external connection connector incorporated in the inside of a phone case in order to obtain an external connection structure of a mobile phone that does not cause the dust-proof cover to be destroyed or lost during use and that can provide a feeling of incongruity. In the external connection structure of a cellular phone that covers the plug insertion opening with a dustproof member that can be opened and closed, a plate-shaped mounting piece that can be bent with a thin hinge as a boundary and a plate-shaped shielding lid are integrally formed from a hard synthetic resin material, and the plug There is one in which the mounting piece is sandwiched and fixed to one side of the insertion port, and the end surface of the shielding lid is pressed against the inner surface of the plug insertion port by a bending reaction force of the thin hinge (for example, see Patent Document 6).

  However, in Patent Document 6, the plug insertion port of the external connection connector incorporated in the inside of the telephone case is covered with a dustproof member that can be opened and closed, but as described above, the yield due to the elastomer resin with respect to the terminal cover, It does not solve the problem of crushing or breaking the rib structure.
