Description
Technical field
The utility model relates to the light modulation film technical field, relates in particular to a kind of conduction screw of light modulation film.
Background technology
Intelligent light modulation film, being also referred to as PDLC (Polymer Dispersed Liquid Crystal) film is a kind of novel electronic control light product, can realize the transformation of clear state to opaque attitude under the effect of electricity.Both can protect privacy, and also can effectively block ultraviolet ray, infrared ray etc., be a kind of novel environment-friendly materials, and majority is used for office, villa, fields such as bank and commercial projection at present.
Light modulation film is to inject the liquid crystal/polymer composite material between the conducting film of two flexibilities, its structure as shown in Figure 1: 11,15 is the transparent flexible substrate layer, and 12,14 is transparent electrode layer, and 13 is the blended polymer liquid crystal layer.Transparent base thickness 0.01-3mm (millimeter), general selection PET (polyethylene terephthalate) are as base material, and product specification is thickness 0.125mm at present, 0.188mm etc.The transparency electrode layer thickness is 10-2000nm (nanometer), and material can be ITO (tin indium oxide) and ZnO (zinc paste) etc., generally selects ITO, the thickness difference, and the transmittance difference generally arrives the hundreds of nanometer tens, and transmittance is more than 80%.The thickness of polymerised liquid crystal layer is generally 5-30 μ m (micron).
Do not having under the situation of electric field, liquid crystal molecule is orientated immediately, because liquid crystal is to the scattering of light effect, this moment, light modulation film was in opaque state; When by transparency electrode light modulation film being applied voltage, liquid crystal molecule is realized arranging in order, owing to the refractive index n of liquid crystal this moment
oRefractive index n with polymkeric substance
pIdentical, then light can pass through, and this moment, light modulation film was in pellucidity.
At present,, need carry out certain cutting, exposing transparency electrode, and then draw lead, connect power supply, drive two conducting films in order to drive light modulation film.This mode is unfavorable for processing on the one hand, is unfavorable for the own cutting of user on the other hand, and it is installed lead in place.
The utility model content
In order to overcome above shortcoming, the utility model provides a kind of conduction screw of light modulation film, neither needs producer that light modulation film is carried out cutting, also makes things convenient for the user lead to be installed in place according to the needs of oneself.
The purpose of this utility model can reach by following measure:
The conduction screw of this light modulation film is made up of screw, the head of a nail, and its special character is: screw rod is made up of I conductive segment, insulating segment, II conductive segment, thread segment, needle point from top to bottom successively.
Described screw is made up of the nut that has wire guide, screw rod.
The length of described I conductive segment, II conductive segment is greater than the thickness of one deck flexible substrate layer and less than the thickness sum of one deck flexible substrate layer and layer of transparent electrode layer, contact electrode layer conduction.
Described insulating segment is made with insulating material, with the consistency of thickness of polymerised liquid crystal layer.
The described head of a nail is that the bottom is provided with threaded hole, the top is provided with the conductive hole composition, penetrates wire guide by power lead and is connected with conductive segment, drives light modulation film.
The utility model is compared with conventional art and is had the following advantages:
The user can cut randomly the size of light modulation film, is installed in the optional position of light modulation film, guarantees the fastness of clamping and the stability of energising.

Fig. 1 is general light modulation film structural drawing.
Fig. 2 is a screw synoptic diagram of the present utility model.
Fig. 3 is a head of a nail back view of the present utility model.
Fig. 4 is a conduction application drawing of the present utility model.
Embodiment
Below with reference to accompanying drawing, specific embodiment of the utility model is described in further detail.
As shown in the figure, the conduction screw 3 of this light modulation film of this kind is made up of screw 31, the head of a nail 32, and its special character is: screw rod 312 is made up of I conductive segment 3121, insulating segment 3122, II conductive segment 3123, thread segment 3124, needle point 3125 from top to bottom successively.
Described screw 31 is made up of the nut 311 that has wire guide 3111, screw rod 312.
The length of described I conductive segment 3121, II conductive segment 3123 is respectively greater than the thickness of one deck flexible substrate layer, and less than thickness sum, contact electrode layer 12 or 14 conductions of one deck flexible substrate layer and layer of transparent electrode layer.
Described insulating segment 3122 usefulness insulating material are made, with the consistency of thickness of polymerised liquid crystal layer 13.
The described head of a nail 32 penetrates wire guide 321 by power lead and is connected with I conductive segment 3121, II conductive segment 3123 for the bottom is provided with threaded hole 322, the top is provided with conductive hole 321 compositions, drives light modulation film 1.
As shown in Figure 5, shear light modulation film 1 according to size during user installation, pass light modulation film 1 at the needle point 3125 that needs the line place with screw 31 then, use thread segment 3124 screwins of the threaded hole 322 corresponding screw rods 312 of the head of a nail 32 again, with fixing light modulation film 1, connect two wire guides 3111,321 respectively with 2 leads then, open the power supply examination at last.
If the user need change the installation site of light modulation film, only need conduct electricity screw to light modulation film and take off, pull down light modulation film then, reinstall light modulation film; If the user need dwindle the area of original light modulation film or be divided into several, a common scissors of needs is original light modulation film cutting or be divided into the new light modulation film that needs size, reinstalls.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
