Description
Technical field
The present invention relates to joints of optical fibre technical field, specifically, relate to a kind of fiber adapter.
Background technology
Along with the development of mechanics of communication, optical fiber is widely used, and fiber adapter is also widely used in continuing of optical fiber Cheng Duanhou.Fiber adapter is the aligning link in Optical Fiber Transmission, and the joints of optical fibre of different interface type can be inserted in two ends, realizes the conversion between distinct interface.Existing fiber adapter, it is generally formed by connecting by several open column, when accessing terminal in box, the limited length of threaded post, and frangibility.
Summary of the invention
Technical matters to be solved by this invention is to provide fiber adapter, and it meets the demand of length in access terminal, and can prevent fracture.
The present invention's adopted technical scheme that solves the problem is:
Fiber adapter, comprise connecting pipe, described connecting pipe comprises the first threaded ends, transition section and the second threaded ends that connect successively, the junction of described transition section and the first threaded ends, the second threaded ends all arranges annular groove, described transition section is provided with the first unidirectional latch and the second unidirectional latch contrary with the first unidirectional latch direction, described transition section is provided with unidirectional latch, the second unidirectional latch match with first respectively the first block, the second block.First threaded ends of the present invention, transition section and the second threaded ends adopt integrated formed structure, and the effective stability improving its structure, makes it not easily be fractureed.First threaded ends and the second threaded ends are respectively used to the connection at two ends.The length of the first threaded ends can adopt existing length, diameter length due to annular groove is less than the diameter length of the first threaded ends, when first threaded ends length is inadequate, can be rotated further and make the first threaded ends continue access terminal or other equipment, even if the groove section of transition section enters the interface of terminating machine, meet the requirement of its access length.First block, the second block can unidirectionally slide, and namely slide respectively to the first threaded ends and the second screw thread two ends, the assembly wall of the first block and terminating machine are close to, strengthen the stability of its structure, annular groove place is not easily fractureed, namely prevent fracture.The effect of the second block is identical with the first block.
As preferably, the described first unidirectional latch is detent projection, the first described block is provided with the detent projection that the detent projection of latch unidirectional with first is corresponding.Utilize detent projection to realize the single-way moving of the first block and the second block, its structure is simple.
Further, the first described block is annulus, and detent projection is positioned on the internal diameter of annulus.Because transition section is cylinder, annulus is utilized to surround transition section, not only be conducive to the unidirectional slip on the first unidirectional latch of transition section of the first block, also the stability of fiber adapter structure is strengthened further, which namely no matter from direction, connecting pipe is exerted a force, first block all can exert a force to the assembly wall of terminating machine, avoids fractureing from annular groove.
As preferably, between the first described block, the second block, be provided with boss.Boss connects the first block and the second block, and both strong second gear block structured stability, also strengthened the stability of transition section interlude structure.
Further, described boss comprises boss and fits in round lower boss with upper boss.Boss adopts Split type structure, is convenient to the installation of boss.
Further, the first described block and the second block are provided with fixed orifice.Utilize fixed orifice to be fixed on the assembly wall of terminating machine by the first block, further improve the stability of its structure, not easily fractureed.
To sum up, the invention has the beneficial effects as follows:
1, the present invention utilizes annular groove to increase the length of access terminal, meets the requirement of its access length, and utilizes the first block and the second block to strengthen the stability of its structure, make its not frangibility.
2, structure of the present invention is simple, is easy to operation.

Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Embodiment 1:
As Fig. 1, fiber adapter described in Fig. 2 and Fig. 3, comprise connecting pipe, described connecting pipe comprises the first threaded ends 1 connected successively, transition section 2 and the second threaded ends 3, described transition section 2 and the first threaded ends 1, the junction of the second threaded ends 3 all arranges annular groove 21, described transition section 2 is provided with the first unidirectional latch 22 and the second unidirectional latch 23 contrary with the first unidirectional latch 22 direction, described transition section 2 is provided with the unidirectional latch 22 with first respectively, the first block 41 that second unidirectional latch 23 matches, second block 42.When not installing, as shown in Figure 1, first block 41, second block 42 is positioned at the interlude of transition section, when after the first threaded ends 1, second threaded ends 3 access terminal or other equipment, the first block 41, second block 42 is made to slide on the assembly wall of terminating machine respectively to two ends, as shown in Figure 3, because the first block 41, second block 42 can only unidirectionally slide, make its Stability Analysis of Structures, can not back skating.
Embodiment 2:
As shown in Figure 1, Figure 2 with the fiber adapter described in Fig. 3, in order to simplify structure, convenient operation, the present embodiment is optimized on the basis of embodiment 1, namely the first described unidirectional latch 22 is detent projection, the first described block 41 is provided with the detent projection that the detent projection of latch 22 unidirectional with first is corresponding.
