Description

Flat vibration motor
Technical field
The present invention relates to a kind of vibrating motor, particularly a kind of flat vibration motor.
Background technology
Flat vibration motor is a kind of micro motor, can be installed in portable phone, smart phone, PDA(Personal Digital Assistant) and similar communication terminal and various other electronic installations.When signal is received by the call center, flat vibration motor can replace sound notification user incoming call by vibration.
More specifically, when being arranged on " politeness paradigm ", communication terminal sends vibration by the operation of this flat vibration motor.
Flat vibration motor is coin-size and produces strong vibration power, so it needs durable relatively syndeton.Yet owing to strong vibration power is out of shape, so contact point is changed its terminal through regular meeting.
Fig. 1 is the stereogram according to the flat vibration motor of correlation technique.
With reference to Fig. 1, comprise stationary part 10, rotor portion (being positioned at stationary part) and base part 30 according to the flat vibration motor of correlation technique.
Stationary part 10 is formed with housing, and rotor portion can be rotatably set in this housing, so the vibration force that rotor portion produces can be transferred to the outside.And stationary part 10 has electric power transfer to the second circuit board 40 of rotor portion and the fixed support 13 that stretches out from its side.Here, second circuit board 40 supports by the fixed support on the stationary part 10 13.
Base part 30 has from the terminal 50 of external source input electric power, and is connected to stationary part 10.Terminal 50 is connected to the second circuit board 40 on the fixed support 13.
In further detail, the base section of terminal 50 utilizes scolder 80 to be fixed between the basal surface and the second circuit board 40 on the fixed support 13 of base part 30.
Base part 30 utilizes binding agent 90 to be coupled to stationary part 10.
Here, after base part 30 assembles, utilizing scolder 80 terminal 50 to be fixed in the process of second circuit board 40, many problems can appear.
Terminal 50 is fixed to second circuit board 40 in its lower end with scolder 80, and its remainder is exposed to the outside.Correspondingly, when terminal 50 making or loading procedure in bear external force be installed in such as the device of communication terminal simultaneously on the time, scolder 80 parts of terminal 50 can be out of shape or break away from, cause contact point change between terminal 50 and the outside terminal.
When scolder does not have hardening, even apply slight power, coupling connection zone just is easy to distortion.During the welding procedure of carrying out on other zones of flat vibration motor, available flatiron is provided with liquid solder.In both cases, between terminal defective contact problems can appear.In addition, influence the outward appearance of product, ropy impression occurred.
And because the excessive heat that produces in welding procedure, base part 30 may be out of shape or burn, and has hindered the effort that reduces the product defects rate.
In addition, utilize binding agent 90 couplings be associated in together base part 30 and stationary part 10 may since the impact that the inefficacy of binding agent 90 or outside apply for example the user fall impact due to the communication terminal and fluff or break away from.
When the coupling connection problem of this stationary part 10 and base part 30 took place, it may bring out the connectivity problem between terminal 50 and the circuit board 40, and interrupted the electric power supply.
Fig. 2 shows the exploded perspective view of the state of the base part 30 that breaks away from the stationary part of flat vibration motor shown in Figure 1 and terminal 50.
With reference to Fig. 2, the rectangular slab of the form of fixed support 13 for stretching out from the side of lower house 12, and second circuit board 40 is arranged on the end face of fixed support 13.
Terminal 50 is formed by contact portion 52, elastic part 54 and bonding part 56.Bonding part 56 is inserted and is fixed between second circuit board 40 and the base part 30, and welds and be connected to the conduction portion 40a of second circuit board 40.
Yet, only utilize the bonding part 56 of terminal 50 to fix (as shown in Figure 2), elastic part 54 and contact portion 52 can not supported by the wall of base part 30 and can be exposed to the outside.Therefore, when terminal 50 was compressed, it lacked support or protection to external force.
When the flat vibration motor with said structure was installed in the device such as communication terminal, the energy terminal of power supply device was treated in contact portion 52 contacts.Here, contact portion 52 and elastic part 54 office, junction surface on the energy terminal produces a certain amount of pressure.
Yet because elastic part 54 can not be supported on all four sides, if load is applied on the elastic part 54 along predetermined direction, it tends to bending or permanent compression, has changed the contact position with the energy terminal of communication terminal.In this case, in manufacture course of products, defective may appear assembling.
In addition, when terminal 50 is not able to take a certain amount of pressure and along the distortion of the direction of pedestal open sides, then its elasticity can reduce, therefore can not keep being used for contacting the enough pressure of outside terminal.
In addition, according to flat vibration motor manufacturing and some complexity of packaging technology of correlation technique.
