Abstract
The utility model discloses a voice coil motor convenient for processing, comprising a plastic cement base and a metal rim and a pin applying on an upper surface of the plastic cement base; the pin is integrated on one side of the metal rim and bends downward; the plastic cement base is provided with a holding tank extending along a height direction and the pin is inserted in the holding tank. Compared with prior arts, the metal rim and the pin of the voice motor are bended and integrated into a whole, which can raise production efficiency of the voice coil motor and realize large scale batch production; meanwhile the pin width is wider, thereby possessing a larger welding area; the integrated moulding pin and metal rim possess good continuity.
Description
Technical field
The utility model relates to a kind of voice coil motor, especially a kind of voice coil motor of being convenient to process.
Background technology
Voice coil motor is applied in the automatic focusing structure of intelligence and high-pixel mobile phone usually, be mainly used in small space realize little stroke, at a high speed, high accelerated motion.
In the existing voice coil motor structure, generally include the plastic cement base, at the upper surface covering quoit of plastic cement base; In the preset hole of the side of plastic cement base, insert the pin pin; In the total, the pin pin will keep in touch conducting with quoit, and there is following defective in existing this structure:
1, installation process is comparatively complicated, is difficult to large-scale mass production.
2, pin pin and quoit contact area are little, cause loose contact easily.
3, pin pin installation many times is not in place, and the part that leaks outside is less, has reduced bonding area, and simultaneously, in order to guarantee the base shape, the width of pin pin is less, directly influences the bonding area of pin pin.
The utility model content
Deficiency to prior art; The purpose of the utility model is intended to provide a kind of voice coil motor of being convenient to process, and its installation process is simple, can realize large-scale mass production; Pin pin and quoit have good conduction, and guarantee that the pin needle set has bigger bonding area.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The voice coil motor of being convenient to process; Comprise the plastic cement base, fit in the quoit and the pin pin of plastic cement base upper surface; It is characterized in that; The pin pin is shaped in a side and the bending downwards of quoit, and the plastic cement base is provided with the holding tank that extends along short transverse, and pin cushion is contained in this holding tank.
Four vertex angle parts of the upper surface of plastic cement base are respectively arranged with a location projection, be provided with on the quoit four with positioning convex column detent one to one.
The beneficial effect of the utility model is:
Than prior art; The voice coil motor of the utility model, its quoit and pin pin one bending and molding have improved the production efficiency of voice coil motor; Can realize large-scale mass production; Simultaneously pin pin width is bigger, thereby has bigger bonding area, and integrated pin pin and quoit have good conduction.
Description of drawings
Fig. 1 is the structural representation of the utility model voice coil motor;
Fig. 2 is the scheme of installation of voice coil motor shown in Figure 1;
Fig. 3 is the assembling process sketch map of the utility model voice coil motor.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing:
Like Fig. 1, shown in 2, the voice coil motor of being convenient to process for the utility model is a kind of, it comprises plastic cement base 1, quoit 2 and pin pin 3; Quoit 2 is fitted in the upper surface of plastic cement base 1, and pin pin 3 is one-body molded with quoit 2, and concrete is; Pin pin 3 is positioned at a lateral edges of quoit 2, and bending downwards is and quoit 2 plumbnesss, and plastic cement base 1 one lateral edges are provided with holding tank 11; This holding tank 11 extends along short transverse, and pin pin 3 is corresponding is arranged in holding tank 11.
Add man-hour, quoit 2 is installed in advance on the mould with plastic cement base 1 and combines to be integrative-structure when the injection moulding.
When quoit 2 and 1 moulding of plastic cement base, utilize mold position, four above-mentioned positioning convex column 12 can be used for following shell fragment fixing and the location voice coil motor.
In the utility model, quoit 2 and pin pin 3 structure that is formed in one, pin pin 3 is formed by one section downward bending that quoit 2 edges stretch out; This structure is convenient to make; The convenient installation, and can make pin pin 3 have bigger width, integrated quoit 2 has good conduction with pin pin 3.As shown in Figure 3, a plurality of quoits 2 formation strip that is arranged side by side is in the course of processing; The strip that a plurality of quoits are formed is fixed on the patrix of mould, treat the mould matched moulds after, to the die cavity injecting glue of mould; After the die sinking, become one structure by the plastic cement base and the quoit strip of sizing material moulding, and the corresponding plastic cement base of each quoit; So, then can realize large-scale mass production, improve production efficiency.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
Claims (2)
1. be convenient to the voice coil motor processed; Comprise the plastic cement base, fit in the quoit and the pin pin of plastic cement base upper surface; It is characterized in that; The pin pin is shaped in a side and the bending downwards of quoit, and the plastic cement base is provided with the holding tank that extends along short transverse, and the pin pin is positioned at this holding tank.
2. the voice coil motor of being convenient to process as claimed in claim 1 is characterized in that, four vertex angle parts of the upper surface of plastic cement base are respectively arranged with a location projection, be provided with on the quoit four with positioning convex column detent one to one.
