Abstract

The utility model discloses a core aligning device for a fusion splicer, which comprises a base and a plurality of V-shaped slotwares, the base and the plurality of V-shaped slotwares are formed respectively, and the V-shaped slotwares are assembled and fixedly connected with the base. Compared with the traditional integral core aligning device for the fusion splicer, in the utility model, the core aligning device which has complex structure and high accuracy requirements is reasonably dismantled to obtain the base and the plurality of V-shaped slotwares so that the shape of the parts is simplified, then the base and the plurality of V-shaped slotwares are respectively formed so as to achieve the purpose of convenience in die machining and manufacturing and in parts forming, then the V-shaped slotwares are assembled and fixedly connected with the base, and after the assembling is completed, a V-shaped slot is arranged at the top of each of the V-shaped slotwares so as to ensure the accuracy of the core aligning device. With the adoption of the core aligning device, the manufacture cost of the die and the parts forming cost are reduced, the long-standing problem of accuracy of die manufacturing and parts forming in the field is solved, and the core aligning device has a good application prospect.

Description

Optical fiber splicer is to core apparatus

Technical field

The utility model relates to the optical fiber splicer field, relates in particular to optical fiber splicer to core apparatus.

Background technology

Optical fiber splicer is the device that connects two sections optical fiber; Being placed on the V-shaped groove two sections optical fiber simultaneously respectively, its tip contacts with each other; Then with the contact point of pair of electrodes near optical fiber; On electrode, apply the heat fusion contact point of high voltage, thereby realize and accomplish two sections fusions between the optical fiber connecting to produce arc discharge and to utilize arc discharge to produce.

Because the diameter of optical fiber has only tens microns, during work, dust in air very easily drops in the V-type track of optical fiber, influences the Aligning degree of optical fiber, thereby causes splice loss, splice attenuation big.Fused fiber splice adopts core or non-to two kinds in core on the current market, and is non-to core type inefficiency, and loss is unstable, though and the core type is cost an arm and a leg, high efficiency, loss is stable, so the market demand is bigger.

But it is complex-shaped to cored structure; Die cost is higher when causing global formation; And mould manufacturing and forming parts difficulty according to domestic existing thermosetting moulding process, are made the used material of high accuracy thermosetting mould and the low precision of former; Raw-material dimensional stability is not enough simultaneously, and these all are unfavorable for making the part complex-shaped, that required precision is high.

The utility model content

The purpose of the utility model just provides a kind of optical fiber splicer to core apparatus, to solve complex-shaped to cored structure that above-mentioned prior art exists, causes the problem of mould manufacturing and forming parts difficulty.

The purpose of the utility model realizes through following technical scheme:

A kind of optical fiber splicer comprises a base and plurality of V slotware to core apparatus, the moulding respectively of base and V slotware, and said V slotware assembling also is fixedly connected on the base.

Said core apparatus is also comprised some screws, said V slotware is spirally connected through screw and base.

Said core apparatus is also comprised be separately positioned on base and the V slotware, and the buckle and the draw-in groove of corresponding clamping, said V slotware passes through buckle and the corresponding clamping of draw-in groove with base.

Said V slotware assembling also is welded on the base.

Said V slotware assembling also is bonded on the base.

Said plurality of V slotware is assemblied on the base and intersects relatively, and the V-shaped groove that is used to place optical fiber is offered at said V slotware top.This V-shaped groove can be offered after V slotware mount is on base again, and assembling V slotware is offered V-shaped groove again and can be guaranteed higher precision earlier.

Compared with prior art, the utlity model has following beneficial effect:

With the optical fiber splicer of traditional global formation core apparatus is compared; The utility model with complex structure, required precision high core apparatus is rationally split into base and plurality of V slotware, part shape is oversimplified, and then moulding respectively; Thereby reach the purpose of being convenient to Mould Machining manufacturing and forming parts; And then with V slotware assembling and be fixedly attached on the base, assembling is offered V-shaped groove at V slotware top after accomplishing; The optical fiber splicer that can obtain the utility model is to core apparatus, and assurance has enough precision.

The utility model reduced the manufacturing cost and the forming parts cost of mould, solved the difficult problem of long-standing mould manufacturing and forming parts precision in this area, has a good application prospect.

Description of drawings

Fig. 1 is the exploded view of the utility model one embodiment;

Fig. 2 is the structural representation after Fig. 1 assembling.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of optical fiber splicer of the utility model comprises two V slotwares 1 and a base 2 to core apparatus, and V slotware 1 is to distinguish moulding with base 2, and design of part is simple relatively, thereby has reduced formed precision and die sinking difficulty.And then V slotware of moulding respectively 1 and base 2 assembled, with 1 assembling of V slotware and be fixedly connected on the base 2.

In the specific embodiment, V slotware 1 can assemble in several ways and be connected on the base 2, as one, sees Fig. 1, and two V slotwares 1 are screwed to the relevant position on the base 2 through screw 3 respectively, thereby realizes V slotware 1 is assembled and is fixed on the base 2; As two, the buckle and the draw-in groove of corresponding clamping is set respectively on base and V slotware, through buckle and the corresponding clamping of draw-in groove, the V slotware is assembled and is fixed on the base; As three, can also the V slotware be welded on the base, accomplish assembling; As four, can also the V slotware be bonded on the base, accomplish assembling; Or the like.

Assembling is as shown in Figure 2 after accomplishing, and two V slotwares 1 are fixed on the base 2 and also intersect relatively.Offer the V-shaped groove 11 that is used to place optical fiber respectively at the top of two V slotwares 1; This V-shaped groove 11 can be offered after V slotware 1 mount is on base 2 again; Also can when 1 moulding of V slotware, offer, earlier assembling V slotware 1 is offered the optical fiber splicer that V-shaped groove 11 can guarantee the utility model again core apparatus is had higher precision.

In addition, when the V of the utility model slotware or base damage, also can the V slotware or the base that damage be pulled down replacing, other parts can continue to use, and help economizing on resources, and reduce cost.

More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
