Next, plate spring part material 6 is described.As shown in Figure 2, the sheet material of plate spring part material 6 resilient materials corrodes postforming.Plate spring part material 6 comprises: be fixed in inside portion 61 on the lens supports body 5, be fixed on outside portion 63 on the collar extension 3, connect a plurality of wrists 62 of inside portion 61 and outside portion 63.Wrist 62 is for obtaining stable elastic property and resistance to impact, vibration resistance are made serpentine shaped.Between the wrist 62 and inside portion 61 in the bight, as shown in Figure 3, owing to disposing the madial wall 33 of collar extension 3, so design is upper some expansions have been carried out at the interval.
As shown in Figure 2, the outside portion 63 of plate spring part material 6 has the tongue 64 that extends laterally corresponding to establishing each bight of the suitable outer peripheral sidewall of wall section 31 with collar extension 3 vertical.Tongue 64 is made elongated shape.Outside portion 63 is by being connected between the bight that configures tongue 64.Outside portion 63 is as shown in Figure 3, has 2 inner side edges, the 34 corresponding outer side edges 65 in bight of the outer peripheral sidewall 31 of corresponding collar extension 3.From then on tongue 64 extends between 2 outer side edges 65.In addition, tongue 64 begins to extend from the inboard from the intersection point that 2 outer side edges 65 have been extended.The top ends of tongue 64 is compared intersection point that this 2 outer side edges 65 have extended and is compared and also will be positioned at the outside.Collar extension 3 is seen from optical axis direction to be 4 angular shapes as mentioned above.As shown in Figure 2, plate spring part material 6 is corresponding to the upper tongue 64 of each bight configuration of collar extension 3.Tongue 64 is made the diagonal of extending to this square shape.Extension is also longer than the distance of the diagonal of the inner peripheral surface of the outer peripheral sidewall 31 of collar extension 3 to the distance that connects between the top of 2 each tongue 64 of plate spring part material 6 diagonals.In addition, tongue 64 preferably is provided with 3 places at least on outside portion 63.
Next, utilize Fig. 3 to describe about plate spring part material 6 and 3 the combination of answering back.After the inboard of the outer peripheral sidewall 31 of collar extension 3 configures the 1st pad 4, utilize the 2nd pad 7 that plate spring part material 6 is accommodated into the inboard of the outer peripheral sidewall 31 of collar extension 3.At this moment, outer side edges 65 is corresponding to the inner side edge 34 of outer peripheral sidewall 31, so, when plate spring part material 6 is pressed into the inside of collar extension 3, can determine the general location of plate spring part material 6.In case further be pressed into, tongue 64 is with after the outer peripheral sidewall 31 of collar extension 3 is docked, and along with distortion, plate spring part material 6 is pressed into the inside of collar extension 3 at optical axis direction.Finally be pressed into to docking with the 1st pad 4.According to the elastic force that is configured in the tongue 64 on the diagonal line correspondence position, the location of each outside portion 63 of plate spring part material 6 is almost same distance with respect to each bight of the outer peripheral sidewall 31 of collar extension 3.That is, the vertical outer peripheral sidewall 31 of establishing the collar extension 3 of section of plate spring part material 6 and fixed body 20 is to determine the position of plate spring part material 6 by the elastic deformation of tongue 64.Bearing accuracy when therefore, plate spring part material 6 is assembled is better.
In addition, tongue 64 more extends from the inboard than the intersection point that extends to 2 outer side edges 65.Therefore, tongue 64 can be longer as the length of elastic start, can easily adjust the location.
Connecting between the bight that in addition, the tongue 64 of outside portion 63 configures., compare than the elastic force of tongue 64, it is high that the integral rigidity of outside portion 63 is wanted for this reason, and the distortion of outside portion 63 of removing tongue 64 is less.Therefore, the locating effect of the elastic force by tongue 64 can be more remarkable.
Be square shape as vertical outer peripheral sidewall 31 of establishing the collar extension 3 of wall section.The diagonal that tongue 64 extends to this square shape.For this reason, the power that collar extension 3 beginnings from the diagonal line are passed on to tongue 64 because with reverse direction on the same size, so cancel out each other.Therefore, the outside portion 63 of plate spring part material 6 is from the equidistant position of the outer peripheral sidewall 31 of collar extension 3, and institute thinks steady state (SS).Accordingly, the outside portion 63 of plate spring part material 6 is difficult to dock with the inner peripheral surface of the outer peripheral sidewall 31 of collar extension 3, can improve bearing accuracy.
Adopted the 2nd pad 7 of the section of pressing material of pressing the frame shape of tongue 64 at optical axis direction.Each tongue of the 2nd pad 7 presses section 71 pushes down tongue.For this reason, because can push down equably each tongue 64, so, than high position precision, can also be more stable.
Next, plate spring part material 11 is described.As shown in Figure 4, plate spring part material 11 is identical with plate spring part material 6, is that the sheet material to resilient material corrodes postforming.Plate spring part material 11 is divided into 2 for consisting of to the current path of coil 9.Identical with plate spring part material 6, it comprises: be fixed on inside portion 111 on the lens supports body 5, be fixed on outside portion 113 on the base 12, connect a plurality of wrists of inside portion 111 and outside portion 113.Wrist 112 is to make the serpentine shaped that can obtain stable elastic property and resistance to impact, vibration resistance.Between the wrist 112 and inside portion 111 in the bight, different from plate spring part material 6, do not configure the madial wall 33 of collar extension 3, so that the interval need not to arrange is roomy.In addition, plate spring part material 11 finally is divided into 2, but inside portion 111 is to be fixed on the lens supports body 5 at least, until outside portion 113 is fixed on the base 12, outside portion 113 further arranges framework (without diagram) the 22 plate spring part materials of cutting apart are constituted one in the outside.Framework is removed after assembling.
As shown in Figure 5, it is corresponding and extend laterally tongue 114 that the outside portion 113 of plate spring part material 11 and base 12 vertical established each bight of the suitable cylindrical portion of wall section 121.2 of plate spring part material 11 divided successes.Outside portion 113 is to be connected between 2 bights of configuration tongue 114 in each 2 of cutting apart.Outside portion 113 has 2 outer side edges 115 corresponding to base 12 outer edges.Tongue 114 extends between these 2 outer side edges 115.In addition, tongue 114 extends in the form of a ring shape from 1.Further, begin to have 2 microspikes 116 to extend from head portion.As shown in Figure 5, the cylindrical portion 121 vertical bights of being located at of base 12.122 relative linea angulata directions of this inner peripheral surface.Being arranged to 2 after microspike 116 is stable docks with inner peripheral surface 122.Base 12 is seen from optical axis direction and is square shape.As shown in Figure 5, plate spring part material 11 is configured to corresponding with each bight of base 12.The diagonal that tongue 114 extends to this square shape.The distance that the top projection 116 of extended 2 tongues 114 connects on the diagonal of plate spring part material 11 is longer than the distance of the diagonal of the inner peripheral surface 122 of the cylindrical portion 121 of base 12.In addition, tongue 114 wishes at least that in the outside portion 113 are arranged to 3 places.In addition, in being divided into 2 plate spring part material 11, extend terminal 117 since 1 outside portion 113 respectively.Power to coil 9 by this terminal 117.
Next, the combination about plate spring part material 11 and base 12 describes with Fig. 5.After the rear end of lens supports body 5 face is fixed the inside portion 111 of plate spring part material 11, on the inboard of the cylindrical portion 121 of base 12, after lens supports body 5 is configured plate spring part material 11, adopt the 3rd pad 10 that plate spring part material 11 is accommodated on the inboard of the cylindrical portion 121 of base 12.At this moment, in the perimeter wall section 123 of outer side edges 115 corresponding bases 12, so, when plate-like portion material 11 is pressed into into the inside of the cylindrical portion 121 of base 12, just can position plate spring part material 11 substantially.Further, in case be pressed into, the microspike 116 of tongue 114 is with after the inner peripheral surface of the cylindrical portion 121 of base 12 docks, and tongue 114 is along with to the optical axis direction distortion, and plate spring part material 11 can be pressed into into the inside of base 12, finally is press-fit into the bottom surface and docks.According to the elastic force of the tongue 114 that configures at the diagonal line correspondence position, each outside portion 113 of plate spring part material 11 is for the cylindrical portion 121 on each bight that is configured in base 12, and its location almost is equidistant.Plate spring part material 11 and fixed body 20 vertical established the cylindrical portion 121 of base 12 of wall section according to the elastic deformation of tongue 114, position that just can plate spring part material 11.Therefore, bearing accuracy is good when assembling plate spring part material 11.
In addition, tongue 114 is compared the intersection point of 2 outer side edges 115 of extension, more extend from the inboard.For this reason, tongue 114 can be longer as elastomeric start length, and it is also easier that the location is adjusted.
In addition, being integral after plate spring part material 11 wraps the outside by framework.For this reason, compare the elastic force of tongue 114, the rigidity of whole framework is higher, and the distortion of removing the plate spring part material 11 of tongue 114 will be still less.Therefore, more remarkable according to the locating effect of the elastic force of tongue 114.
The zone that surrounds by vertical cylindrical portion 121 of establishing the base 12 of wall section is square shape.The diagonal that tongue 114 extends to this square shape.For this reason, the power that base 12 beginnings from diagonal line are passed on to tongue 114 is in the opposite direction equal size, so cancel each other.The most stable state when therefore, the outside portion 113 of plate spring part material 11 begins to be positioned on the equidistant position from the cylindrical portion 121 of base 12.Therefore, the outside portion 113 of plate spring part material 11 is difficult to be docked on the inner peripheral surface of cylindrical portion 121 of base 12, can improve bearing accuracy.
Use with tongue 114 press to optical axis direction, be the 3rd pad 10 of the section of the pressing material of frame shape.Each tongue of the 3rd pad 10 presses section 101 and presses tongue 114.For this reason, because can push down equably each tongue 114.So hi-Fix also can make it stable simultaneously.
And in this example, the fixed part 20 of accommodating plate spring part material 6 is collar extension 3, also can be not limited to this.Such as, in the front side of collar extension 3, the effect that framework plays framework can be set.Plate spring part material 6 is not in the inboard of collar extension 3, can be arranged on the inboard of framework yet.At this moment, framework is seen as polygon from optical axis direction and is built up on the optical axis direction, and side can arrange the vertical wall of establishing of accommodating the plate spring part material within it.
In addition, tongue 64,114 shape can be established the conditions such as wall section shape, size, plate spring part material 6,11 size, leaf spring thickness according to fixed part 20 vertical, can freely design.For example, tongue 64 and the replacement of tongue 114 shapes can be come.Also the microspike 116 of tongue 114 can be arranged to 1, also can be more than 3.
In addition, in this example, the fixed part 20 of seeing from optical axis direction be shaped as square shape.Configured tongue 64,114 on each bight, but tongue 64,114 can be more than 3.At this moment, configure tongue 64,114 for fixed part 20 being passed on cancel each other to tongue 64,114 power.In addition, fixed part 20 is triangle, also can be the pentagon shape.
