Description

  The present invention relates to a portable device to which a strap (hanging string) can be attached.

  Conventionally, favorite straps have been attached to portable devices typified by mobile phones for the purpose of improving removal from pockets and bags, improving owner identification, and preventing device dropping. The portable device is provided with a strap attachment portion for that purpose. This strap attachment part is often provided at the corner of a portable device by opening the strap through-holes on two different sides of the housing so that the strap can be easily passed. There is a case where the arrangement in the corner of such a portable device is restricted due to a request for making it.

  For example, a mobile terminal called a smartphone employs a built-in fixed antenna made of a molded circuit product in place of a telescopic rod antenna that can improve communication sensitivity by extending it as a communication antenna. Things are increasing. Built-in fixed antennas are generally placed in the upper and lower parts including the corners of the mobile device to allow better transmission and reception of radio waves while avoiding other components in the mobile device and gripping parts by the user's hand. Has been. In a mobile terminal with an antenna built in such an arrangement, it is difficult to arrange the strap attachment portion at the corner when it is intended to be provided without raising the casing from the viewpoint of design.

  In the case described above, a structure in which the strap through-hole is opened on the same side surface of the casing at a portion deviated from the corner of the mobile terminal is suitably employed for the strap attachment portion. As a structure of such a strap attaching portion, a hooked portion to which a strap inserted through the through hole is wound and fixed is formed integrally with the housing, and a guide surface for guiding the strap is provided on the inner surface of the through hole. The structure is known. As an example, Patent Document 1 discloses a device in which a strap winding surface in a hooked portion (second winding portion) is formed in a curved shape or a flat shape in order to prevent damage to the strap. Yes.

  In recent years, it has become common for mobile devices to adopt a waterproof structure that prevents the entry of water from the outside into a housing that houses electronic components. As a waterproof structure for portable devices, it is known that the gap between housings and parts is sealed with a waterproof material such as packing or double-sided tape made of a flexible material such as rubber, a waterproof sheet, a bond, or a gel. It has been. In order to ensure waterproofing of the inside of the housing by such a waterproof structure, the strap attaching portion is preferably provided in a portion independent of the component housing portion of the housing, that is, in a non-waterproof region outside the housing.
