Background technique
Bending resistance fold-type lateral emitting optical fiber sensor is designed with photosensitive mouth on the head of inductive probe and side.
The working principle of fibre optical sensor is that the optical signal from light source on an optical cable transmission to detectable substance by carrying out
Detection device is output to by another optical cable again after being reflected on through an optical cable transmission to detection object after reflection
In parsed, with obtain the distance between testee and sensor or the testee speed of service, time interval etc. ginseng
Number.Existing traditional fibre optical sensor is only equipped with photosensitive mouth in one end of inductive probe, and side detection installation is more troublesome, needs
The installation space wanted is bigger, along with traditional fiber-optic sensor probe generally uses fixed round splce or square joint,
The angle between probe and optical cable can not arbitrarily be changed, freedom degree is low.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model provides, and a kind of side can be carried out luminous detection, detector
The sensor resistant to bending with the coupling part of cable.
The technical solution of the utility model is as follows:
A kind of bending resistance fold-type lateral emitting optical fiber sensor, including optical cable, inductive probe and connector, the inductive probe
It is set on the optical cable with the connector, further includes that the inductive probe is equipped with the first photosensitive mouth and the second photosensitive mouth, it is described
First photosensitive mouth is set to one end of the inductive probe, and the second photosensitive mouth is set to inductive probe side；It is described
Optical cable and the inductive probe junction are equipped with protective case, and the protective case is sheathed on the outside of the inductive probe.
Preferably, the sheath is rubber sheath, the sheath is equipped with through-hole.
Preferably, the connector includes male-pipe and locking nut.
Preferably, the male-pipe and the locking nut are threadedly coupled connection.
The utility model has the advantage that compared with prior art
1, inductive probe side is equipped with photosensitive mouth, detects convenient for the lateral emitting of sensor, the model of further expansion detection
It encloses, when detection is more convenient.
2, figure is more very thin, can also install in narrow space, save installation space.
3, the angle between inductive probe and optical cable can freely be adjusted in 0 ° to 180 °, so that inductive probe freedom degree
High, when detection, is more convenient.
4, rubber sheath can greatly protect inductive probe and optical cable connecting portion, so that the optical cable of the coupling part is more
Add bending resistance folding.
