Abstract
The utility model relates to a fluting type pottery lock pin installs on metal flange, including the lock pin body, lock pin body center be provided with and be used for inserting the through -hole of establishing optic fibre, the front end of lock pin body is provided with the chamfer, the notch of holding elasticity sealing washer is seted up to the rear end of lock pin body, the rear end outside of lock pin body is provided with is connected fixed bulge loop with metal flange. The utility model discloses simple structure, production is convenient, in the ceramic lock pin of elasticity sealing washer arrangement income, supports and leans on metal flange is last, has realized zonulae occludens's effect on the one hand, has avoided the gouging abrasion of pottery lock pin, on the other hand elasticity sealing washer wearing and tearing back is removable to protected ceramic lock pin, makeed ceramic lock pin dismantle many times and still can keep between them the compactness connected, and be unlikely to to damage.
Description
Technical field
The utility model relates to optical fiber interface component technical field, particularly relates to a kind of shaped grooved ceramic insertion core.
Background technology
Optical fiber ceramic lock pin, also known as ceramic ferrule.The right cylinder of precise centering in optical fiber connector plug, there is a micropore at center, as fixed fiber.It is a kind of by nano zircite (ZrO2) material through a series of formula, the high precision special cermacis element that processes, its aperture, out of roundness error are 0.5 Jing.Made connector is fiber active linker that is detachable, classification, makes the connection of optical channel, conversion scheduling more flexible, can for the debugging of light way system and maintenance.
Existing ceramic insertion core is all generally directly be plugged on metal flange, and it is also unreliable to connect, and at ceramic insertion core after repeatedly plug and produces the wearing and tearing being difficult to avoid between metal flange, thus connection is no longer tight.
In view of above-mentioned defect, the utility model creator obtains this creation finally through long research and practice.
Utility model content
The purpose of this utility model is, provides a kind of shaped grooved ceramic insertion core, in order to overcome above-mentioned technological deficiency.
For achieving the above object, the technical solution adopted in the utility model is, a kind of shaped grooved ceramic insertion core is provided, be installed on metal flange, comprise lock pin body, described lock pin body central is provided with the through hole for plugging optical fiber, and the front end of described lock pin body is provided with chamfering, the rear end of described lock pin body offers the notch of accommodating elastic seal ring, and the rear end outer setting of described lock pin body has the bulge loop be connected and fixed with metal flange.
Preferably, described lock pin body back edge position is also provided with fillet.
Preferably, described metal flange comprises the bolt that middle part has passage, and described bolt front end has the extension coordinated with described bulge loop, is provided with screw thread in the mounting hole of described metal flange.
The beneficial effects of the utility model are compared with the prior art:
Because described elastic seal ring is resisted against on described metal flange; achieve close-connected effect on the one hand; avoid the gouging abrasion of described ceramic insertion core; replaceable after described elastic seal ring wearing and tearing on the other hand; therefore described ceramic insertion core is protected; ceramic insertion core is repeatedly dismantled still can keep the compactedness connected between them, and be unlikely to damage.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the shaped grooved ceramic insertion core of the utility model;
Fig. 2 is the structural representation that the shaped grooved ceramic insertion core of the utility model is connected with metal flange.
Embodiment
Below, embodiment of the present utility model will be described with reference to the accompanying drawings.In embodiments, the part of same configuration uses identical Reference numeral and omits and describes.
Consulting Fig. 1, is the sectional structure schematic diagram of the shaped grooved ceramic insertion core of the utility model; Composition graphs 2 is the structural representation that the shaped grooved ceramic insertion core of the utility model is connected with metal flange.
As shown in FIG., described ceramic insertion core, comprise lock pin body 1, described lock pin body 1 center is provided with the through hole 2 for plugging optical fiber, described lock pin body 1 front end is provided with chamfering, the rear end of described lock pin body 1 offers notch 4, in order to accommodating elastic seal ring 10, makes contacted with metal flange 7 by described elastic seal ring 10 and avoid the gouging abrasion of described lock pin body 1 when installing.The rear end outer setting of described lock pin body 1 has bulge loop 6, for being connected and fixed with metal flange 7, makes metal flange 7 more closely reliable with the connection of described ceramic insertion core.
Described lock pin body 1 back edge position is also provided with fillet 5, collides the harmful effect brought when described fillet 5 can prevent lock pin body 1 to be connected with metal flange 7.
And as shown in Figure 2, metal flange 7 comprises the bolt 8 that middle part has passage 81, and described bolt 8 front end has the extension 82 coordinated with described bulge loop 6, is provided with screw thread in the mounting hole 9 of described metal flange 7.
When described ceramic insertion core is installed to metal flange 7, first in the described notch 4 of described ceramic insertion core, insert described elastic seal ring 10, again the described ceramic insertion core being provided with described elastic seal ring 10 is inserted in the mounting hole 9 of described metal flange 7, then bolt 8 is tightened on described mounting hole 9 through ceramic insertion core front end, with coordinating of extension 9, ceramic insertion core and metal flange 7 is fixed by described bulge loop 6.
Because described elastic seal ring 10 is resisted against on described flange 7; achieve close-connected effect on the one hand; avoid the gouging abrasion of described ceramic insertion core; described elastic seal ring 10 is replaceable after wearing and tearing on the other hand; therefore described ceramic insertion core is protected; ceramic insertion core is repeatedly dismantled still can keep the compactedness connected between them, and be unlikely to damage.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for the utility model, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that the utility model claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
