Abstract

The invention provides a connection device which is capable of pivotally connecting two housings without a connecting section projecting from the housings, and capable of stably holding the housings when the housings are in an open state. A connection device has a first and a third connection member (31, 33) that have flexibility and foldably fix an upper housing (1) and a lower housing (2) with a connection section in between. The connection device further has a second connection member (32) that has a restoring force and rigidity returning from a folded state to an open state and has a cross-section with a circular-arc shape curved and recessed toward the folding direction of the upper and lower housings.

Description

technical field

[0001] The present invention relates to a connecting device for foldably connecting two housing parts, and to a smaller electronic device and a folding portable terminal device having the connecting device. Background technique

[0002] In recent years, various types of mobile phones have been developed and used. For example, mobile phones include bar-type mobile phones and folder-type mobile phones that can be folded by hinges.

[0003] The foldable mobile phone includes: an upper case in which a display unit is provided; a lower case in which an operation unit is provided; and a hinge part which foldably connects the upper and lower cases so that the display unit and the operation unit face each other. This structure causes the upper housing to rotate relative to the lower housing on the central axis of the hinge. The hinge has a substantially cylindrical shape, and the outer diameter of the hinge is generally larger than the thickness of the upper and l...
