Coin Vibration Motor with FPC(new type coin motor for mobile phone

Abstract:

A new type coin vibration motor includes a motor body and an FPC board provided with a gold finger, one end of the line of the FPC board is electrically connected to a power receiving end in the coin vibration motor, and the other end of the line of the FPC board is connected with a gold finger, the gold finger Used to connect to a mobile terminal. The utility model changes the wire method of the manual solder to the FPC lead-out mode by changing the lead-out mode of the coin vibration motor electrode, and then elects the gold finger of the FPC and the PIN pin on the mobile phone to cancel the welding wire station, thereby improving the installation efficiency. And reduce the hidden dangers such as rosin or tin residue caused by welding, and improve the quality.

At present, the market share of smart phones is expanding, and the corresponding market share of Coin vibration motors for mobile phones is also increasing. At the same time, mobile phones are moving toward miniaturization and ultra-thinness, and new patches are also proposed for their use. Requirements: Ultra-thin and ultra-miniature, and can be standardized manufacturing like other electronic components.

According to market requirements, the new flat motor has achieved the smallest volume and the minimum thickness can be as low as 3.4_. However, while the size of the motor is reduced, the conventional motor shape and structure also cause the following problems.

The positive and negative lead-out methods of the conventional flat motor are lead-out. When the customer uses it, the wire needs to be soldered to the pad, which requires manual operation. In the practical process of the motor, not only the process needs to be increased, but also the solder will cause rosin residue and dross. Wait for foreign matter.

The coin vibration motor body and the FPC board provided with a gold finger, one end of the line of the FPC board is electrically connected to the power receiving end in the coin vibration motor, and the other end of the line of the FPC board is connected with the gold finger, and the gold finger is used for connecting movement terminal.

Preferably, the flat motor further includes a tray, and the FPC board is fixed on the tray.

The advantages of the new model are:

By changing the lead-out method of the motor electrode, the wire method requiring manual soldering is changed to the FPC lead-out mode, and then the gold finger on the FPC and the PIN pin on the mobile phone are energized to cancel the welding wire station, thereby achieving Improve installation efficiency and reduce the risk of rosin or tin residue caused by welding, and improve quality.
