Plastic optical fiber (POF) is a kind of by high transparency polymer, as polymethyl methacrylate (PMMA),
Fluoro-containing plastic is the optical fiber of sandwich layer, compared to silica fibre, plastic optical fiber light weight, softness, more resistant to bending and
Vibration, but due to its fibre core greatly, easily couple, often do not account for tool when designing the union joint of communication device
Body uses environment, causes at connector position loss of signal big, decreases its transmission range.
In engineering uses, as in plastic optical fiber power information acquisition system, use the transmission of red-light source
Distance is at about 100 meters, owing to the connected mode of current union joint is by the circuit board with light source emitter
Abutting joint direct with plastic optical fiber, in lug, does not accounts for the access efficiency of light signal, adds
Onsite application environment SGI is more, further increases insertion loss and the bit error rate of joint, makes reality
Use distance to reduce, affect transfer rate.
Summary of the invention
The present invention is to solve above-mentioned technical problem, it is provided that a kind of insertion loss reducing joint and mistake
Code check, extend actually used distance, improve transfer rate engineering plastic optical fiber joint.
The technical solution of the present invention is:
A kind of engineering plastic optical fiber joint, including rosette with the circuit board of light source emitter, it is special
Different part is: is provided with Optical fiber plug in rosette one end, is provided with axial through wires hole in Optical fiber plug,
And the outer face of Optical fiber plug is bell mouth shape, the outer circumferential walls of Optical fiber plug is provided with card circumferentially
Ring；This engineering plastic optical fiber joint is additionally provided with the fiber-optical socket of tubular, sets on the inwall of fiber-optical socket side
The buckle that circumference is evenly arranged, described circuit board is had to be arranged on fiber-optical socket opposite side end face, and circuit board
On light source emitter be positioned at fiber-optical socket and with fiber-optical socket concentric, and near light in fiber-optical socket
At the emitter of source, convex lens is set.
Further, described rosette is to be made up of box body and upper cover, arranges correspondence between box body and upper cover
Latch hook and locked groove, and it is provided with just to the arc card line projection arranged at box body inner bottom surface and upper cover inner top surface, just
In gripping optical fiber.
Further, described box body, upper cover, the plug being located on box body and snap ring are made up of plastic material
Integrative-structure.
Further, described fiber-optical socket and be located at buckle thereon and be made up of plastic material.
The invention has the beneficial effects as follows:
1, owing to being provided with snap ring circumferentially in the outer circumferential walls of Optical fiber plug, and in fiber-optical socket side
Inwall is provided with the buckle that circumference is evenly arranged, and Optical fiber plug is inserted in fiber-optical socket, the card on Optical fiber plug
Ring and the snap lock on fiber-optical socket, make the plastic optical fiber being arranged in the through wires hole of Optical fiber plug be in envelope
In the space closed, simple in construction, it is convenient to install, and effectively avoids the entrance of dust, extends actual making
By distance, improve transfer rate.And the outer face of Optical fiber plug is bell mouth shape, when operation is installed, light
Fine to penetrate end concordant with horn mouth internal orifice, decreases optical fiber and penetrates end and pollute because touching external environment condition.
2, owing to arranging convex lens at light source emitter in fiber-optical socket, will be dissipated by convex lens mirror
Flashlight focus at plastic optical fiber, increase local light intensity, reduce insertion loss and the error code of joint
Rate.
