Abstract

The utility model relates to a novel audio frequency optical fiber joint, which is divided into a head, a center section and a holding section. The utility model is characterized in that the joint forms a hollow pipe shape, and inner diameters which steadily increases with an order of small size, middle size and big size are axially formed in the joint, wherein every different internal diameter respectively corresponds to a core wire of an optical fiber conductor and an inner and an outer coatings, the big diameter of the holding section is provided with one to two slots which are penetrative in radial direction, and clamp sheets which have thread holes are inserted on the slots respectively. Because the utility model can be formed in a mode of integral forming of plastic, the process of combination and installation is very convenient, thereby, work efficiency is improved effectively. The corresponding clamp sheets clamp and press conductors after the optical fiber conductor is sheathed. Because the thread hole of the clamp sheets is embedded in the skin of the conductor, the outward disengagement of the conductor can be prevented effectively and the effect of steady and reliable connection can be obtained.

Description

The novel audio fibre-optical splice

The utility model belongs to the communication class product, relates in particular to-kind of novel audio fibre-optical splice.

The audio frequency fibre-optical splice is mainly used in the input and output of digitized audio optical fiber, shown in figure six, it is existing audio frequency fibre-optical splice and optic fibre wire combination synoptic diagram, the hollow tube that partly is made of metal of adapter body wherein, its front end skin is socket one gum cover then, optical fiber coating is peelled off, and coating and heart yearn in it are exposed in layering, when lead and adaptor cup jointing, its heart yearn front end has the extremely short joint front end that partly extend out to, its outer coating penetrates to the joint rear end again, because outer coating external diameter produces the block effect greater than the joint front inner diameter, make lead and joint after socket, make the joint rear end be pressed in coating within the lead of corresponding position in the mode of pressing again, finish engaging of optic fibre wire and joint with this.

Aforementioned fibre-optical splice has following shortcoming:

1. joint (18) constitutes its body partly with metal, front end place socket one gum cover (17), because optic fibre wire (9) is to be used to conduct light source, visible gum cover (17) is not to make insulation applications, so it is unnecessary with glue material formation, indispensable part in the also non-use, for its necessary element, on processing procedure but must with other-number of assembling steps gives and to be linked, joint metal body appearance change is more again, cost is higher during machine-shaping, also comparatively bothers in the manufacturing.

The mode of connection of joint (18) and optic fibre wire (9) be with the joint rear end that presses to compress this interior coating of place's lead (9) (11), this kind combination only is used for clamping, and is difficult for fastening.When often being subjected to rightabout pulling force, the phenomenon that gets loose and separate is arranged then as joint (18) and lead (9).

The purpose of this utility model is exactly in order to address the above problem, and provides-kind of novel audio fibre-optical splice.The novel audio fibre-optical splice, be divided into head, center section part and grip part three parts, it is characterized in that this joint is hollow tubular, inner little axially to be formed with, in, the internal diameter that increases progressively of big order, each different inner diameters corresponds respectively to the heart yearn and the inside and outside coating of optic fibre wire, 1--2 slot that radially runs through arranged at the large diameter place of grip part, be inserted with the intermediate plate in band line hole on the slot respectively.

The utility model has been compared following advantage with existing audio frequency fibre-optical splice:

1. simple and convenient assembly: the utility model can the one-body molded mode of plastic cement constitute, the joint design of this operation is formed in one, head, center section part and grip part are arranged, after itself and the optic fibre wire socket, and after the intermediate plate on the relative cramping grip part, promptly finish the binding of joint and lead,, thereby effectively promoted work efficiency so assembling process is very easy.

2. in conjunction with firm: the utility model is after optic fibre wire is inserted in, and the cramping intermediate plate is with clamping wire relatively, and because so with in the insertion wire epidermis, outwards deviate from can effectively prevent lead in the line hole of intermediate plate, and obtains firmly firm connection effect.

Describe in detail below in conjunction with accompanying drawing.

Number in the figure is as follows:, (1) joint of the present utility model, (2) head, (3) center section part, (4) grip part, (5) side grain, (6) slot, (7) intermediate plate, (8) line hole, (9) optic fibre wire, (10) heart yearn, (11) interior coating, (12) outer coating, (13) little internal diameter, (14) internal diameter in, (15) large diameter, (16) slotted eye, (17) gum cover, (18) existing joint

As shown in Figure 1, the novel audio fibre-optical splice, be divided into head, center section part and grip part three parts, it is characterized in that this joint is hollow tubular, inner little axially to be formed with, in, the internal diameter that increases progressively of big order, each different inner diameters corresponds respectively to the heart yearn and the inside and outside coating of optic fibre wire, and 1--2 slot that radially runs through arranged at the large diameter place of grip part, is inserted with the intermediate plate in band line hole on the slot respectively.

Center section part (3) and grip part (4) all are cylindric, wherein upper and lower end face, grip part (4) has a side grain (5) respectively, on side grain (5), there are two and radially run through slot (6), be inserted with an intermediate plate (7) in two slots (6) respectively, the rectangular shape of each intermediate plate (7), the centre of intermediate plate (7) has a line hole (8), and this line hole (8) is lip shape.

As shown in Figure 2, this joint (1) is inner to have little inside diameter (13), middle inside diameter (14), large diameter portion (15) respectively from front end, this is little, in, large diameter portion is with axial stepped being interconnected, the head (2) of its medium and small inside diameter (13) penetrator front end, joint (1) large diameter portion (15) rear end has one to communicate and run through the slotted eye (16) of rearward end, penetrates for optic fibre wire (9).

Optic fibre wire (9) by joint (1) rear end axially to penetrate, wherein lead (1) front end is peeled off outer coating (12), thereby successively expose its heart yearn (10) and internal coated layer (11), this heart yearn (10) and in coating (11) exposed length should cooperate little in the joint, middle footpath axial length, in optic fibre wire (9) penetrates joint (1), to pass the line hole (8) on two intermediate plates (7) in regular turn, front end heart yearn (10) will be corresponding in the little inside diameter (13), the interior coating (11) of heart yearn (10) rear end will be subjected to the inboard end wall block of middle inside diameter (14), and outer coating (12) then is subjected to the inboard block of large diameter portion (15).

When lead (9) inserts joint (1) to the location, pass the line hole (8) of intermediate plate (7) simultaneously, as shown in Figure 3, this moment, intermediate plate (7) upper and lower side slightly exposed slot (6) in addition, with the cramping instrument to the relative cramping of intermediate plate (7), when intermediate plate (7) during by cramping, because line hole (8) is lip shape, line hole (8) inner width will be compressed relatively, and make coating (11) within the relative insertion wire of its groove edge (9), so not only make intermediate plate (7) be clamped in joint (1) inside, and the lead that will insert simultaneously (9) clamp.
