Description
Technical field
The utility model relates to the optical fiber step lock pin that is used for optical communication equipment, particularly a kind of optical fiber step lock pin with the sheath fixed orifice.
Background technology
Because the develop rapidly of communication career is with universal, optical communication has become people's life, the necessary means of working, and constantly to hypervelocity, high capacity, the development of long range direction.
In optical fiber communication technology develop rapidly at present under the new situation, small optical fiber parts all can affect the development of optical-fibre communications cause greatly; For example, ceramic optical fiber step lock pin is the link of optical system, and it is transmitting light signal with connector.Usually, the center of optical fiber step lock pin is a fiber cores, and the lock pin afterbody is provided with a taper hole, with glue the naked fibre optical fiber of sheath (only with) and ceramic insertion core is sticked together.In order to prevent that optical fiber from use fractureing, also be provided with the sleeve pipe of protection optical fiber etc. at the rear portion of lock pin.Nonetheless, in use still there is easily broken drawback in optical fiber.Disconnected fine in order to prevent, people try every possible means fiber optic protection, cause difficulty of processing increasing, and cost is more and more higher.Find out later on that through conscientious analysis it is very firm that fibre core is fixed in lock pin, and the sheath of optical fiber can only lean on the taper hole of lock pin afterbody and glue to fix, end and a small amount of sheath external diameter of fixing zone some fibre core and optical fiber jacket.Problem just goes out in the fixing length of optical fiber jacket not enough, fibre core and sheath are finished on that bonding position, also be in loose bonding state between them, the phenomenon of this loose combination be because fibre core and sheath in work such as cut-out, peeling, perforation and bonding fibre core, the external force of the various ways that the person of being operated applies makes optical fiber be implemented into positioning requirements in motions such as softening, change, push away, draw and produces.In this case, merely by above-mentioned binding function reach the protection sheath effect will be very small.
It is cheaper to continually develop price, volume is smaller and more exquisite, use simpler, it is more reliable to work, more permanent novel optical communication equipment of life-span, transmission network, relay station, detecting instrument etc. have become one of new problem that this field scientific research personnel is badly in need of researching and developing, and a kind of application optical fiber step lock pin wherein is provided, and improve contact reliability, to adapt to the demand of production in enormous quantities, primary especially prerequisite.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and a kind of optical fiber step lock pin of band sheath fixed orifice of simple in structure, dependable performance is provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of optical fiber step lock pin with the sheath fixed orifice, comprise the lock pin body, described lock pin body center is axially arranged with fiber-optic fixing-hole, afterbody is provided with entrance hole, the optical fiber of band sheath enters along entrance hole, and its fiber core partly inserts fiber-optic fixing-hole; It is characterized in that described lock pin body afterbody is provided with and the friction tight sheath fixed orifice of sheath; Described entrance hole is located at sheath fixed orifice front end, and entrance hole is tapered, is provided with glue-line in the described entrance hole.
The beneficial effects of the utility model are: its simple in structure, dependable performance, and the optical fiber integrally constant intensity improves greatly, and the optical fiber situation of fractureing significantly reduces.The step lock pin of band sheath fixed orifice can adopt injection moulding production, the qualification rate height, and high conformity, technology is simple.Its specific structure design makes its price cheaper, and volume is smaller and more exquisite, uses simplyr, and it is more reliable to work, and the life-span is more permanent; Be mainly used in optical communication equipment, the light signal switch board, transmission network, relay station is in the optical communication testing tool; It is big to be particularly suitable for density of optic fibre, the occasion that working environment is narrow and small.The utility model is suitable for large-scale production in enormous quantities, has boundless market outlook as the upgraded product of ceramic insertion core.
Description of drawings
Fig. 1 is an existing fiber step lock pin structural representation;
Fig. 2 is the utility model lock pin body part structural representation;
Fig. 3 is the whole syndeton synoptic diagram of the utility model.
Among the figure: 1 lock pin body, 2 fiber-optic fixing-holes, 3 entrance holes, 4 sheath fixed orifices, 5 sheaths, 6 glue-lines, 7 fiber cores, 8 loose bound fractions.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As Fig. 2～shown in Figure 3, a kind of optical fiber step lock pin with the sheath fixed orifice comprises lock pin body 1, described lock pin body 1 center is axially arranged with fiber-optic fixing-hole 2, afterbody is provided with entrance hole 3, and the optical fiber of band sheath 5 enters along entrance hole 3, and its fiber core 7 parts are inserted fiber-optic fixing-hole 2; It is characterized in that described lock pin body 1 afterbody is provided with and sheath 5 friction tight sheath fixed orifices 4; Described entrance hole 3 is located at sheath fixed orifice 4 front ends, and entrance hole 3 is tapered, is provided with glue-line 6 in the described entrance hole 3.
For example, make lock pin body 1 with zirconia ceramics, the center is axially arranged with fiber-optic fixing-hole 2, and this hole is strict concentric with fiber core 7 external diameters, matches with fiber core in the aperture; Expand to taper hole subsequently, promptly entrance hole 3, are used to import optical fiber and fixed fiber.In order to reduce optical fiber causes optical fiber when bonding in entrance hole 3 distortion, the tapering of the entrance hole 3 of this structural design reduces, and promptly entrance hole 3 and the diameter of sheath fixed orifice 4 joining parts are less than sheath fixed orifice 4 diameters.Like this, both made and held the minimizing of glue space, and optical fiber can have been cemented again, this taper hole has the function that imports fiber core and cement fibre core and optical fiber jacket.Key is in the end to hold to be provided with cylindrical sheath fixed orifice 4, and its diameter and optical fiber jacket are complementary, and the length of sheath fixed orifice 4 will enough guarantee sheath 5 bonding firm, and the length of general sheath fixed orifice 4 is more than or equal to the diameter of sheath 5.
Like this, the loose part of sheath 5 ends is inserted in ceramic insertion core inside fully, after confirming to stretch in the sheath fixed orifice 4, with glue sheath 5 external diameters and ceramic insertion core is cemented again to fiber core 7 and sheath 5 compact optical fiber.The disconnected in actual applications fine probability of improved this lock pin structure declines to a great extent, and product obtains success greatly.Contrast existing fiber lock pin shown in Figure 1, wherein loose bound fraction 8 very easily causes the damage of fibre core and even fractures, and the quality that influences lock pin greatly improves.
Above-mentioned detailed description of the optical fiber step lock pin of this band sheath fixed orifice being carried out with reference to embodiment; be illustrative rather than determinate; can make all size as required; therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
