Abstract

The invention discloses a VCM (voice coil motor) lower cover structure facilitating terminal mounting. Bosses in L-shaped structures are arranged on side walls at four corners of a body and used for glued joint with an outer housing; a lower elastic sheet groove is formed at the top of the body; a first groove is formed at an opening of the body and used as a transfer groove of a carrier to move downwards; a dustproof ring is arranged at the opening of the body; elastic sheet glue dispensing columns are arranged at the four corners of the body corresponding to the lower elastic sheet groove; terminal mounting ports are formed at every two connected corners of the body respectively; and the terminal mounting ports comprise terminal top end grooves and terminal lower end openings. The structure is simple in design; a lower cover is well connected with a lower elastic sheet, the carrier and the outer housing; and the problems of deformation, breakage and excessive expense of a terminal can be effectively improved.

Description

technical field [0001] The invention relates to a VCM lower cover structure which is easy to install terminals, and belongs to the technical field of voice coil motors. Background technique [0002] A voice coil motor is a device that converts electrical energy into mechanical energy, and realizes linear and limited swing angle motion. A device that uses the interaction between the magnetic field from the permanent magnet steel and the magnetic poles in the magnetic field generated by the energized coil conductor to produce regular motion. Because the voice coil motor is a non-commutating power device, its positioning accuracy depends entirely on the feedback and control system, and has nothing to do with the voice coil motor itself. With appropriate positioning feedback and sensing devices, the positioning accuracy can easily reach 10NM, and the acceleration can reach 300g. [0003] At present, the existing structure of the lower cover and the terminal adopts an integrate...
