Abstract

Disclosed are an actuator capable of preventing interference caused by torsion to thereby improve stability and reliability, and a spring used for the actuator. The actuator includes a first molding part, a second molding part being rotatably connected in an end of the first molding part, and a spring member including a first spring arm that is fixed to the first molding part and a second spring arm that is fixed to the second molding part. In this instance, the first spring and the second spring arms are integrally connected to each other.

Description

technical field [0001] The present invention relates to an actuator and a spring used for the actuator, more particularly, to an actuator capable of preventing interference caused by twisting so as to improve stability and reliability and a spring used for the actuator. the actuator spring. Background technique [0002] A slide-type mobile phone may use an actuator to provide elasticity. The actuator may provide a driving force so that the body portion and the slide portion may operate semi-automatically or automatically. A typical actuator is a torsion spring comprising a coiled elastic portion. Therefore, both ends of the torsion spring are mounted in the sliding hinge or body to provide the force for sliding. [0003] A conventional spring includes a coiled elastic portion and a wiring portion extending from the coiled elastic portion. The coiled elastic part is bent into a helical shape on the same plane. However, a disadvantage is that conventional springs cannot b...
