Embodiment
Below, embodiment of the present utility model is described.
At first, for easy to understand formation of the present utility model, formation in the past is described at first, the limit represents that the difference limit of formation of the present utility model and formation in the past describes then.
Fig. 1 is the figure that the formation of entirety of lens package body 1 in the past is described.
Fig. 1 represents entirety of lens package body 1, and entirety of lens package body 1 possesses 4 lens 11～14 and has the thing side opening and imaging side opening and be formed with the lens frame 10 of the hollow bulb that 4 lens 11～14 are inserted in the mode of optical axis alignment.
Represent following situation at this Fig. 1, that is, and in order to obtain anti-dust performance and water resistance easily, according to making the neighboring contact each other of each lens 11～14, in the lens frame 10 of packing into to optical axis alignment, and the diameter of lens is along with becoming the situation that big mode constitutes lens 11～14 towards the thing side.Represent to have the imaging side that is being disposed at by in the lens outer peripheral face of the lens 14 of thing side that the diameter waterproof part configuration portion 141 littler a section than thing side part partly is set at this Fig. 1, and the later state of the lens frame 10 of behind its waterproof part configuration portion 141 configuration O type rings 15, packing into.As shown in Figure 1, O type ring 15 is loaded into the state that is clamped in lens frame internal face 100 and waterproof part configuration portion (following also on the books the configuration of the O of being type ring portion) 141.
In the formation of this Fig. 1, as above-mentioned, in the time will packing lens 14 into lens frame 10, can not positively press the O type ring 15 that is encased in the lens frame earlier, thereby, the phenomenon that O type ring 15 comes off from its O type ring configuration portion 141 takes place.
So, following formation is proposed in the present embodiment: as shown in Figure 2, with regard to lens 14A, thing side in the outer peripheral face of these lens 14A partly is provided with and is formed the diameter waterproof part configuration portion 141A littler a section than imaging side part, prevents the formation that comes off of O type ring 15A at the O type ring of this waterproof part configuration 141A of portion configuration waterproof part 15A.
Fig. 2～Fig. 5 is the figure of the entirety of lens package body of an expression embodiment of the present utility model.
Except that the formation of the formation of the formation of lens frame 10A and lens 14A and O type ring 15A is changed, represent the entirety of lens package body 1A of the formation identical at Fig. 2 with Fig. 1.Represent to have the state of the entirety of lens package body 1A after the O type ring 15A of packing at Fig. 2, represent to have the enlarged drawing of the O type loop section that Fig. 2 has been installed at Fig. 3.And, Fig. 4 represent to have packed into after the O type ring 15A and carried out crimping processing after the state of entirety of lens package body 1A, represent to have the enlarged drawing of part of the O type ring of the entirety of lens package body that Fig. 4 has been installed at Fig. 5.
In Fig. 1, when lens frame 10 is packed lens 14 into, part in the lens frame of packing into is provided with waterproof part configuration portion 141 earlier, but in formation shown in Figure 2, thing side in the outer peripheral face of the 1st lens partly is provided with and is formed the diameter waterproof part configuration portion 141A littler a section than imaging side part, and disposes the O type ring 15A of waterproof part at this waterproof part configuration 141A of portion.
For this reason, just can the limit positively press O type ring 15A limit and be encased in lens frame 10, the effect of the O type ring 15A that can obtain to pack into easily with hand etc.And as Fig. 2, shown in Figure 3, can also obtain can be from the effect of the state of packing into of outside Visual Confirmation O type ring 15A.
On the other hand, after the O type of packing into the ring 15A, as shown in Figure 4, the thing side opening frame 101A that forms the thing side opening of said lens frame 10 is crimped and is processed into: in the complete all scopes of this thing side opening the thing side of O type ring 15A is pushed.If like this, as shown in Figure 5, O type ring 15A just is deformed into the thing side opening frame 101A of suitable lens frame 10A and the shape in the space between the lens outer peripheral face 141A, and obtains outstanding water resistance.At this, add man-hour carrying out above-mentioned crimping, can adopt thermo-compressed or ultrasound wave crimping.
Use elastomeric elements such as EP rubbers, silicon rubber at O type ring 15A.Need to prove, material as lens frame, can consider to use PA (polyamide), PPA (polyphtalamide), PPS (polyphenylene sulfide) etc., as the O type ring of waterproof part, also can make up the moulding product of POM (polyoxymethylene), PE (tygon), PP (polypropylene), PC (poly charcoal acid ester), LCP low melting point materials such as (liquid crystal polymers) at the lens frame of making by these materials.So, if the fusing point of the material of waterproof part is lower than lens frame, then when carrying out thermo-compressed, the moulding product suitably be out of shape and with thing side opening frame 101A welding, thereby water resistance uprises.
As described above, realization is enclosed in waterproof part the entirety of lens package body of lens frame easily.
Herein, the shape of the type ring configuration 141A of portion of configuration O type ring 15A, not necessarily the shape of Fig. 1 also can obtain corresponding effects.
Fig. 6 is the figure corresponding to Fig. 3, represents the figure of the difform example of the O type ring configuration 141A of portion shown in Figure 3.
As the O type ring configuration 141B of portion shown in Fig. 6 (a), also can be by the circular R of forming shape be done in the bight of the O type ring configuration 141A of portion shown in Figure 3, and catch O type ring 15A easily.And, as the O type ring configuration 141C of portion shown in Fig. 6 (b), give cone shape a little so that the side of configuration O type ring 15A broadens, and, also can also give cone shape a little at a side 142C who catches O type ring 15A, dispose O type ring 15A easily from the outside, and, also the leading section of lens 14A can be scraped circle (chamfering) and it is scraped round part as the 141D of configuration portion.
In any case, by crimping processing, the O type ring 15A of waterproof part just in time is fit to, as shown in Figure 5 so can obtain corresponding effects.
At last, illustrate entirety of lens package body 1A shown in Figure 4 is applicable to the example of lift-launch in the situation of the camera of automobile.
Fig. 7 is the figure that expression possesses the camera unit 2 of entirety of lens package body 1A shown in Figure 4.
Represent that at Fig. 7 the truncation surface that blocks camera unit 2 along optical axis is arranged.
In assembling during this camera unit 2, at first the entirety of lens package body 1A of Fig. 4 is inserted into while being screwed into after the camera main- body frame 20,1A is adhesively fixed on camera main-body frame 20 with the entirety of lens package body.At this moment, by at the neighboring of lens frame 10 and the leading section coating adhesive of camera main-body frame 20, carry out water-proofing treatment, so that water does not enter camera unit inside from front.And, the substrate 210 that carries imaging apparatus 21 such as CCD solid-state imager is adhesively fixed on camera main-body frame 20.Can be assembled in the camera unit 2 by the entirety of lens package body 1A of this simple order Fig. 4.
As described above, realize easily lens frame pack into waterproof part the entirety of lens package body and possess the camera head of its entirety of lens package body.
