Problems solved by technology

[0004] However, the conductive terminals are highly elastic, and the sealing ring is made of elastomer (rubber), so they respectively have unnecessary vibrations that are separated from the rotational vibration of the eccentric hammer, and lateral shaking is easy to occur on the conductive terminals.

Abstract

A vibration motor. The use of such a vibration motor can better suppress the lateral shaking of the conductive terminal. It has a pair of motor power supply parts, a pair of plate-shaped conductive terminals, and a partition part. The motor power supply part is arranged on the end cover that closes the open end of the motor housing. The pair of plate-shaped conductive terminals include contact surfaces for contact with The contacts for power supply which are arranged on one side of the substrate and are elastically stretchable are in contact with each other, and the plate-shaped conductive terminal is connected to the motor power supply part at a position corresponding to the motor power supply part. The peripheral surface of the motor housing abuts to separate the contact surface from the peripheral surface, wherein the first contact surface as a whole has a first stopper that abuts against the first side surface of the partition portion, and the second The contact surface as a whole has a second stopper portion abutting against a second side surface of the separator which is a side surface different from the first side surface of the separator.

Description

technical field [0001] The present invention relates to a vibrating motor with an eccentric weight, in particular to an assembled vibrating motor, the plate-shaped conductive terminal can abut against the elastically shrinkable power supply contact on the side of the substrate where it is installed. Background technique [0002] Generally, conventional vibration motors have a pair of elastic conductive terminals, and such motors are assembled in a state where the conductive terminals are brought into contact with a power supply pattern on the substrate side. However, due to the vibration of the vibration motor itself and the impact of external vibrations, the elastic conductive terminals tend to shake laterally on the power supply pattern, thus hindering the electrical contact. In order to improve this defect, Japanese Patent Laid-Open No. 2002-330567 discloses a structure for improving this defect. [0003] That is, in this structure, a pair of recesses are provided on a g...
