Spring for a slide module, and slide module using same

Abstract

The present invention relates to a spring for a slide module, which is applied to a small terminal having a slide module and a electrical line such as a data line or a power line penetrating therethrough, such as a portable communication terminal operating in a sliding system, to reduce the thickness of the terminal employing the spring, and wherein said spring has a structural stability to maintain the elasticity or shape thereof in a good condition, and to thus smoothly assist in the sliding motion of the terminal over a long period of time. The spring for a slide module according to the present invention couples units of a slide-type portable terminal operating when supplied with power such that the units are slidable relative to one another, and comprises a coil unit and a pair of leg units. The coil unit includes an interconnection portion, and a first coil and a second coil which are stacked into layers, in such a manner that at least a portion of the first coil and at least a portion of the second coil are out of line when viewed from the front of the circle of the layer to enable the circle of the layer of the first coil and the circle of the layer of the second coil to have different centers. The leg units are extended in opposite directions, from each end of the first coil and the second coil, and the extended ends of the leg units are rotatably coupled to the slide module. The coil unit and the leg units are formed into a shape in which two sides facing each other are parallel to each other, and the segment perpendicularly interconnecting said two sides has a length shorter than that of any one of said two sides in the cross-section in the thickness direction of the shape.

Description

Technical field [0001] The present invention relates to a torsion spring for a sliding module and a sliding module using the technology. More specifically, it is suitable for a small terminal, such as a portable communication terminal operated by a sliding movement method. The sliding module is equipped with a power cord such as a data cable. By setting it in the inner direction, the ultra-thin structure of the related terminal can be better displayed, and the original elasticity and shape can be preserved through the stability of the structure, and the sliding of the related device can be flexibly supported even if used for a long time. Background technique [0002] The produced mobile phone has a smaller specification and is a wireless communication device that enables users to carry and make calls easily. Such mobile phones can be divided into flip-type, folder-type, sliding-type, etc. according to their appearance or operation mode. [0003] The sliding type mobile phone descr...

Problems solved by technology

[0019] Another object of the present invention is to provide a torsion spring for a sliding module and a sliding module using the same technology, so as to ensure that no deformation occurs due to the phenomenon that the number of sliding operations increases and becomes more frequent due to the diversification of the functions of the sliding mobile phone or weakened elasticity
