Abstract

The present invention discloses an FPC board. The FPC board comprises an upper layer, a middle layer and a lower layer. The upper layer is a protective film made of an insulating material, the lower layer is a substrate made of an insulating material, and the middle layer is a circuit layer made of copper foil. The FPC board is provided with a first through hole for cooperating with the coil; oneend of the protective film is provided with a plurality of first escape grooves for cooperating with the lead wire of the coil; and the circuit layer is provided with a plurality of first connection portions corresponding to the first escape grooves. The present invention also provides a linear motor to which the FPC board is applied. According to the technical scheme of the present invention, thefirst escape groove reserves a mounting space for the lead wire of the coil, and is convenient to install; and the lead wire of the coil is placed in the first escape groove and soldered to the firstconnection portion on the circuit layer, so that not only a certain protection function for the lead wire of the coil can be realized, and good stability, safety and reliability can be achieved, butalso the vibration space of the motor is increased, the vibration amount of the motor is improved, and a good vibration effect is achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an FPC board and a linear motor using the same. Background technique [0002] With the rapid development of electronic products, especially mobile terminal devices such as mobile phones and tablet computers, these electronic devices basically use vibration generators to prevent noise from electronic devices from disturbing others. The traditional vibration generating device uses a rotor motor based on eccentric rotation, which realizes mechanical vibration through the rotation of the eccentric vibrator. During the rotation of the eccentric vibrator, the commutator and brushes will generate mechanical friction and electric sparks, etc., which will affect The rotational speed of the eccentric vibrator further affects the vibration effect of the device. Therefore, current vibration generating devices mostly use linear motors with better performance. [0003] Linear motors, also know...
