Between limited, increase multiple light blocking components and bring inconvenience to processing and manufacturing, assemble also more difficult.
Accordingly, it would be desirable to a kind of anti-optical crosstalk structure solves the problems, such as optical crosstalk.
Content of the invention
Goal of the invention：For the deficiencies in the prior art, applicant is improved through repeatedly practice, devises a kind of anti-optical crosstalk knot
Structure, assembling are simple, and anti-optical crosstalk effect is good.
Technical scheme：In order to realize foregoing invention purpose, the technical scheme adopted by this utility model for：A kind of anti-optical crosstalk
Structure, including the first housing, the second housing, light guide plate and wiring board, first housing, wiring board, the second housing are sequentially held in the mouth
Connect, dismountable light guide plate is housed on the wiring board.
Further, the one side of described light guide plate is provided with parallel multiple light-guiding pillars, gap between the light-guiding pillar
Equal.
Further, mounting groove is provided with above the light guide plate.
Further, the light guide plate is colorless and transparent.
Further, the first described housing is provided with the mounting groove for accommodating light-guiding pillar, is provided with and is in the light between the mounting groove
Wall.
Further, the second described housing is provided with light barrier, and the light barrier is inserted in the gap of the light-guiding pillar.
Further, the wiring board is provided with light source, and the light source is respectively provided on two sides with draw-in groove.
Further, the quantity of the light source of the mounting groove of the first housing, the light-guiding pillar of light guide plate and wiring board is identical,
The position of the light source of the mounting groove of the first housing, the light-guiding pillar of light guide plate and wiring board corresponds.
Further, the wall that is in the light of first housing, between the light barrier of the second housing and light-guiding pillar gap quantity
Identical, the position in gap between wall, light barrier and light-guiding pillar of being in the light corresponds.
Yet further, the first half of the light-guiding pillar is embedded in the mounting groove of first housing.
Beneficial effect：A kind of anti-optical crosstalk structure of the present utility model, installs simply, and anti-optical crosstalk effect is good, does not increase extra
Anti- optical crosstalk part, so as to reduce cost.
