Description

L type optical fiber X-over

The utility model relates to a kind of L type optical fiber X-over.

Because the sustainable development of the progress of science and technology and industry, many high-tech electronic products, Communication Equipment, and household appliances such as audio-visual media all have been widely used among the life of society, this has not only promoted people's quality of the life, more gives people's information transmission more efficiently and reappears effect with more distortionless image and tonequality.

Yet all household appliances such as high-tech electronic product, Communication Equipment or audio-visual media all need utilize cable transmission of digital signal, and the cable of electric signal transmission is developed the high-efficiency transfer media that has been transformed into the optic fibre wire transmission so far by early stage plain conductor.

Plain conductor was in the process of signal transmission in the past, very easily because in the metal cause of resistance coefficient make signal reach by first ground via plain conductor a distant place second the time, cause the loss of signal, and make the reproduction poor effect of former signal, but the Optical Fiber Transmission lead does not have the shortcoming of above metal transfer wire, and it is less that it has diameter, capacity is big and transmission is quick, be not subjected to an advantage such as extraneous noise interference, not only lower the distortion rate and noise interference of signal transmission greatly, more quicken the signal transmitting speed and used by society gradually.

Yet traditional straight type Optical fiber plug is after inserting fiber-optical socket, because of protruding, plug is easy to drop, and take up room, and most fiber-optical socket all is arranged at the position, rear of household appliances, and household appliances are to place near the wall place in many occasions, so after the plug of fiber cabling inserts fiber-optical socket, if because the distance of household appliances and wall is less, then the wiring of straight type Optical fiber plug just needs bending, it is right if crooked flexibility is improper, then can influence the quality of optical fiber signal transmission, even cause the consequence that to transmit, so the transfer wire of the straight type Optical fiber plug transformation of the way becoming L type Optical fiber plug is just arisen at the historic moment.

The structure of traditional L type Optical fiber plug as shown in Figure 5, it is the cut-open view of L type Optical fiber plug, this is integrated L shell body 60, in the bending place 61 of housing 60, be provided with and avoid optic fibre wire 70 to cause the bad guide groove of laser propagation effect 62 because of bending is improper, and being provided with fixed fiber lead 70, an end place of housing 60 enters chock 63 in the housing 60, the other end then has a tip side 64 by extending in the housing 60, be provided with optic fibre wire 70 in the tip side, so the state that optic fibre wire 70 just can the L type combines with the fiber-optical socket (not shown) of machine rear end, does not bend situation generation improperly and do not have.

Above-mentioned structure no doubt can be avoided the existing problem of straight type optic fibre wire in the use, but therefore the user still has the use inconvenience in use if because of it needs to use under the preferable situation of straight type optic fibre wire, then can't replace.

Present in addition employed fiber cabling plug branch has two kinds of specifications, wherein a kind of is the long n pin package ns of 3.5 φ, another kind of is the fine wiring angle type plug (toslink) of short footlights, just the patchplug side of must arranging in pairs or groups is used on the household appliances that are provided with the long n pin package n socket of 3.5 φ if the fiber-optical socket on the household appliances when cooperating the plug socket of the long n pin package n of 3.5 φ, is then lacked the fiber cabling of pin angle type plug.

Given this, fundamental purpose of the present utility model is to provide a kind of L type optical fiber X-over, to make things convenient for the user under any circumstance, all can utilize this X-over to reach the purpose of straight type or L type optical fiber transmission line, can obtain to exchange between the fibre-optical splice of different size the L type optical fiber X-over of effect again.

For reaching above-mentioned creation purpose, the technical solution of the utility model is a kind of L type optical fiber X-over, and wherein: this joint is provided with Optical fiber plug in an end of L shell body, and the other end is provided with holder, be formed with slot on the holder, and be connected with optic fibre wire between holder and Optical fiber plug.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme as can be known, the utility model in use, can make the user under any circumstance, all can utilize this L type optical fiber X-over of the present utility model to reach L type optical fiber transmission line or do not use the utility model and directly utilize the purpose of straight type fibre-optical splice on fiber-optical socket, can also reach the effect of exchanging between the fibre-optical splice of different size.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.

Fig. 1 is the stereographic map of the utility model L type optical fiber X-over embodiment.

Fig. 2 is the three-dimensional exploded view of the utility model embodiment.

Fig. 3 is the stereographic map of another embodiment of the utility model.

Fig. 4 is a cut-open view embodiment illustrated in fig. 3.

Fig. 5 is the cut-open view of traditional L type fibre-optical splice.

Now please referring to shown in Figure 1, it shown in the figure stereographic map of the utility model L type optical fiber X-over embodiment, the outward appearance of its optical fiber conversion becomes the L type, one end of its housing 10 has the long n pin package n 12 of 3.5 φ by interior extending, and the other end then can insert to reach the purpose of changing between the different size plug for short pin angle type plug 20.

Now please referring to shown in Figure 2, it shown in the figure three-dimensional exploded view of Fig. 1 embodiment, find out inner structure of the present utility model by knowing among the figure, the housing of the utility model embodiment is divided into two parts, one is the procapsid 100 of L type, another then is a back casing 101, one end of L type procapsid 100 is provided with the long n pin package n 12 of 3.5 φ, the other end and back casing 101 collocation then are formed with a socket 11, be provided with a holder 13 in the socket 11, but optical fibre lead 30 in the holder 13, this optic fibre wire 30 also is connected to the long n pin package n of 3.5 φ 12 places by holder 13 places.

Now more please referring to shown in Figure 3, plug design for the different size of arranging in pairs or groups, originally the long n pin package n of 3.5 φ 12 places can make short pin angle type plug 15 into, other structure is then as the structure of aforementioned patchplug, the shell body of short pin angle type plug 15 is then for making the structure of 360 deg rotation with respect to housing 10, when the shell body of short pin angle type plug 15 is done the 360 deg rotation with respect to housing 10,150 of fibre-optical splices in type plug 15 shell bodies 151 of short pin angle not relatively housing 10 do the 360 deg rotation.

Now please referring to Fig. 4, it shown in its figure the cut-open view of another embodiment of the utility model L type optical fiber X-over, be formed with in the holder 13 of the present utility model can ccontaining short pin angle type plug (not shown) slot 16, optic fibre wire 30 shown in the figure is arranged in the housing 10, and extend to type plug 15 places, short pin angle by holder 13 places, and 13 of optic fibre wire 30 and holders are provided with a fixture 17 with convenient that optic fibre wire 30 is fixing on holder 13.
