Abstract
The present invention provides plastic casing used for optical fiber adapter, wherein the plastic casing inner wall having two symmetric semicircular grooves, bell guide at plastic casing two ends convenient for optical fiber flexible jumper ceramics pin inserting, an axial direction slotting at plastic casing side. Said invention has advantages of contact insertion and withdraw force of 300-600g, insertion loss less than and equal to 0.4 db.
Description
Technical field
What the present invention relates to is a kind of plastic casing that is used for fiber adapter, belongs to the optical communication technique field.
Background technology
At present, optical adapter sleeve on the market all is to adopt stupalith, and reason is that the wearing quality of stupalith is good, but the problem of using stupalith to exist is: ceramic sleeve complex manufacturing technology, cost height; Ceramic sleeve is very easily fragmentation etc. in use.
Summary of the invention
The objective of the invention is to the defective at above-mentioned existence, propose a kind of plastic casing that is used for fiber adapter, it can effectively overcome defectives such as existing in prior technology complex manufacturing technology, cost height.
Technical solution of the present invention: its structure is that the plastic casing inwall has two semicircular grooves, the position symmetry, the two ends of plastic casing have is convenient to the bell guide that the fiber active linker ceramic contact pin inserts, the side-closed of plastic casing or have axially grooved.
Advantage of the present invention: the technical indicator of fiber adapter sleeve most critical is the optical property index of sleeve, promptly inserts the wearing quality of loss, bush material and the contact engaging and separating force of sleeve.The key that loss is inserted in control is to control the dimensional accuracy and the form and position tolerance of sleeve well, selects for use suitable Shooting Technique can reach requirement; Select appropriate plastic material for use, its wearing quality can reach requirement.This patented product especially is fit to the application of FTTH (Fiber to the home).This patent selects for use the good plastic material of anti-wear performance to replace stupalith, and sleeve adopts the injection moulding mode to make, and has not only simplified manufacture craft, and has solved the frangible problem of sleeve.
Description of drawings
Accompanying drawing 1 is the side-closed synoptic diagram of this plastic casing.
Accompanying drawing 2 is that the side of this plastic casing has an axially grooved synoptic diagram.
Accompanying drawing 3 is this plastic casing concrete application synoptic diagram at FC type fiber adapter.
Among the figure 1 is shell, the 2nd, plastic casing, the 3rd, semicircular groove, the 4th, bell guide, the 5th, flange, the 6th, side-closed, 7 be one axially grooved, the 8th, the plastic casing internal diameter.
Embodiment
Contrast Fig. 1, its structure is that the two ends of plastic casing have the bell guide 4 of being convenient to the insertion of fiber active linker ceramic contact pin, and the side-closed of plastic casing 2 promptly also is provided with two semicircular grooves 3 at the plastic casing inwall, position symmetry, the cylindrical of plastic casing 2 have flange 5 one.
The internal diameter size of plastic casing is Φ 2.5mm or Φ 1.25mm.
Contrast Fig. 2, its structure is that the two ends of plastic casing have the bell guide 4 of being convenient to the insertion of fiber active linker ceramic contact pin, the side of plastic casing 2 has one axially grooved 7.Plastic casing 2 inwalls do not have two semicircular grooves 3, and the outer fenestra of plastic casing 2 does not have flange 5 one.
The internal diameter size of plastic casing is Φ 2.5mm or Φ 1.25mm.
Contrast Fig. 3, the shell 1 of FC type fiber adapter is made of two parts symmetrical, and plastic casing 2 is installed within it, and two shells 1 are realized connecting by ultrasonic soldering, and plastic casing 2 portion within it has axially and activity space radially.
By above description, those skilled in the art are easy to make some to the technology that is disclosed and change and equivalent variation, as being applied to, above-mentioned patented product also the profile of patented product can be made some variations in the fiber active linkers such as SC type, ST type, LC type, MU type.When the ceramic contact pin of fiber active linker inserted half position of sleeve pipe, its contact engaging and separating force should be 300g～600g.The precision of plastic casing can make the insertion loss≤0.4dB with its supporting fiber active linker when butt joint that is connected.
Claims (3)
1, a kind of plastic casing that is used for fiber adapter, the two ends that it is characterized in that plastic casing have is convenient to the bell guide that the fiber active linker ceramic contact pin inserts, and there is the side-closed of an axially grooved or plastic casing side of plastic casing.
2, a kind of plastic casing that is used for fiber adapter as claimed in claim 1 is characterized in that the side-closed of described plastic casing promptly also being provided with two semicircular grooves at the plastic casing inwall, the position symmetry, and the cylindrical of plastic casing has flange one.
