Abstract

An optical fiber connector comprises a flange body on which a first leading-in passage and a second leading-in passage are arranged, wherein the first leading-in passage and the second leading-in passage are communicated with each other in the flange body, a first switch-in passage is arranged in the first leading-in passage, both the first leading-in passage and the second leading-in passage are provided with external threads, the flange body further comprises a second switch-in passage, and the second switch-in passage is connected with the second leading-in passage in a clamped way after extending into the second leading-in passage. The utility model adopts the same use method as the conventional optical fiber connector, so that the second connecting passage directly extends into the second leading-in passage and is clamped with the second leading-in passage. The second connecting passage and the second leading-in passage can be conveniently connected without being damaged.

Description

A kind of joints of optical fibre

(1) technical field

The utility model relates to a kind of joints of optical fibre.

(2) background technology

The application of optical fiber more and more widely, the joints of optical fibre that therefore are used between optical fiber and the optical fiber are also developed rapidly.The general structure of the present joints of optical fibre is: comprise flange body, flange body is provided with first introduction channel and second introduction channel, first introduction channel and the conducting in flange body of second introduction channel, be provided with first in first introduction channel and insert passage, be provided with second in second introduction channel and insert passage, first introduction channel and second introduction channel all have external thread.Be one between the first access passage and first introduction channel wherein, ceramic body is filled in from second introduction channel, and then the second access passage is pressed in second introduction channel.When connecting optical fiber, two optical fiber are inserted into respectively in first interface channel and second interface channel, and then on the external thread of first introduction channel and second introduction channel, realize being connected by nut screwing clamping.Its shortcoming that also exists of the existing this joints of optical fibre is: second introduction channel and second connected mode that inserts passage easily make second interface channel or second import interface channel and produce damage.

(3) summary of the invention

In order to overcome the above-mentioned deficiency of existing fiber connector, the utility model provides that a kind of second interface channel easily is connected with second introduction channel, the non-damageable joints of optical fibre.

The technical scheme in the invention for solving the technical problem is: a kind of joints of optical fibre, comprise flange body, described flange body is provided with first introduction channel and second introduction channel, described first introduction channel and the conducting in described flange body of second introduction channel, be provided with first in described first introduction channel and insert passage, described first introduction channel and second introduction channel all have external thread, it is characterized in that: comprise that also second inserts passage, described second inserts passage stretches into behind described second introduction channel and the described second introduction channel clamping.

Further, described second outer wall that inserts passage is provided with buckle, and the inwall of described second introduction channel is provided with bayonet socket, and described buckle buckles in the described bayonet socket.

Further, second corresponding with the described buckle outer wall that inserts passage is provided with the axial slit that extends to the second channel end.

Using method of the present utility model is identical with the using method of the existing joints of optical fibre, when inserting second interface channel in second introduction channel, only needs that the second access passage is directly inserted second introduction channel and makes both clamping get final product.

The beneficial effects of the utility model are: second interface channel is connected easy, both difficult generation breakages when connecting with second introduction channel.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

(5) embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

With reference to Fig. 1, a kind of joints of optical fibre comprise flange body 1, and described flange body 1 is provided with first introduction channel 2 and second introduction channel 3, described first introduction channel 2 and the conducting in described flange body 1 of second introduction channel 3 are provided with first and insert passage 4 in described first introduction channel 2.Described first introduction channel 2 and second introduction channel 3 all have external thread.Comprise that also second inserts passage 5, described second inserts passage 5 stretches into described second introduction channel 3 backs and 3 clampings of described second introduction channel: described second outer wall that inserts passage 5 is provided with a buckle 6, the inwall of described second introduction channel 3 is provided with bayonet socket 7, and described buckle 6 buckles in the described bayonet socket 7.Second outer wall that insert passage corresponding with described buckle 6 is provided with axial two slits 8 that extend to the second channel end, and in inserting process, slit 8 can help second to insert passage 5 and produce distortion, is beneficial to second and inserts inserting of passage 5.

Claims

1. joints of optical fibre, comprise flange body, described flange body is provided with first introduction channel and second introduction channel, described first introduction channel and the conducting in described flange body of second introduction channel, be provided with first in described first introduction channel and insert passage, described first introduction channel and second introduction channel all have external thread, it is characterized in that: comprise that also second inserts passage, described second inserts passage stretches into behind described second introduction channel and the described second introduction channel clamping.

2. the joints of optical fibre as claimed in claim 1 is characterized in that: described second outer wall that inserts passage is provided with buckle, and the inwall of described second introduction channel is provided with bayonet socket, and described buckle buckles in the described bayonet socket.
