Surface could be formed with the material in optical reflection face 130, can also be formed without the material in optical reflection face 130.Fin 124 can
Bevel structure 122 applied to Fig. 2 to Fig. 5 B.
Fig. 9 is painted the partial enlargement with optical reflection face 130 of the bevel structure 122 of another embodiment according to the present invention
Figure.The places different from Fig. 2 embodiment are: 122 inclined-plane of bevel structure can also have groove 126, and groove 126 is recessed
Sink into the gap 132 in optical reflection face 130.That is, the position of groove 126 corresponds to the position in gap 132, groove 126
Surface could be formed with the material in optical reflection face 130, can also be formed without the material in optical reflection face 130.Groove 126 can answer
Bevel structure 122 for Fig. 2 to Fig. 5 B.
Figure 10 is painted the perspective view of the upper cover 120a of another embodiment according to the present invention.Figure 11 is painted the upper cover of Figure 10
Sectional view of the 120a along line segment 10-10.0 and Figure 11, optical reflection face 130c are formed in bevel structure 122 refering to fig. 1 simultaneously
Chamfered surface, and impurity absorption film 131 is formed on the 130c of optical reflection face.The places different from Fig. 2 embodiment are: light
The gap 132 that reflecting surface 130c does not have Fig. 2 is learned, but optical reflection face 130c is covered by impurity absorption film 131.In addition, noise
The material of absorbing film 131 may include the nonmetallic of light-permeable.
When impurity absorption film 131 connects with the optical reflection face 130c for not having gap 132 applied to the optics of Fig. 3 A and Fig. 3 B
When connecing device 100, impurity absorption film 131 and orthographic projection of the light source 150 on substrate 110 are least partially overlapped, and impurity absorption film
131 is least partially overlapped with orthographic projection of the optical detector 160 on substrate 110.Such design, it is miscellaneous when light source 150 shines
News absorbing film 131 not only can absorb the noise that light source 150 is coupled to optical reflection face 130c, also can absorb from optical reflection face
130c is coupled to the noise of optical detector 160.In this way, which optical conenctor 100 can still have low electromagnetic crosstalk and low noise
The effect of interference.In the present embodiment, optical reflection face 130c can be to be formed on the inclined-plane of bevel structure 122 to contain gold
Belong to the film of ingredient, and the film containing metal component is between impurity absorption film 131 and the inclined-plane of bevel structure 122, it is such
Film can be metal alloy layer, also can be multilayered structure, can also be to spread multiple conducting particles in dielectric film.At it
In his embodiment, the material of bevel structure 122 can be metal, then the inclined-plane of bevel structure 122 itself just can be directly as
Optical reflection face is not required to form the film containing metal component.
Figure 12 is painted another embodiment of the upper cover 120a of Figure 11.Optical reflection face 130c is to be formed in bevel structure
The film containing metal component on 122 inclined-plane.The places different from Figure 11 embodiment are: impurity absorption film 131,133
It is located on opposite two surfaces 135,137 of the film containing metal component.Wherein, impurity absorption film 133 is located at bevel structure
Between 122 inclined-plane and the surface 137 of the film containing metal component.
When impurity absorption film 131,133 and the optical reflection face 130c for not having gap 132 are applied to the light of Fig. 3 A and Fig. 3 B
When learning connector 100, impurity absorption film 131,133 and orthographic projection of the light source 150 on substrate 110 are least partially overlapped and miscellaneous
It interrogates absorbing film 131,133 and orthographic projection of the optical detector 160 on substrate 110 is least partially overlapped.Such design, works as light source
150 it is luminous when, impurity absorption film 131,133 not only can absorb light source 150 and is coupled to the noise of optical reflection face 130c, can also inhale
Receive the noise that optical detector 160 is coupled to from optical reflection face 130c.In this way, which optical conenctor 100 can still have low electricity
The effect of magnetic cross-talk and low noise interfere.
Although the present invention is disclosed above with embodiment, however, it is not to limit the invention, any to be familiar with this skill
Person, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations, therefore protection scope of the present invention is worked as
Subject to the scope of which is defined in the appended claims.
