Problems solved by technology

[0003] When the current optical fiber is actually connected, the device generally wraps the ferrule of the optical fiber and the optical cable for protection, which makes it difficult to align the insertion of the optical fiber, and it is easy to cause friction loss due to incomplete matching at the joint, reducing the loss of the optical fiber joint. service life, and after the optical fiber is docked, it is easy to be contacted by external objects, resulting in the interface of the docked optical fiber being loose and disconnected due to force, reducing the stability of the docking of the optical fiber access device

Embodiment 1

[0036] Example 1, as Figure 1-Figure 2 As shown in the figure, when the light access work is performed, a part of the ferrule 4 can be inserted into the inner layer of the access channel 7 and fit with the clamping surfaces of the lower arc-shaped clamping plate 61 and the upper arc-shaped clamping plate 65 , at this time, the threaded rod 62 can be rotated to drive the internal thread block 63 and the lower arc clamping plate 61 and the upper arc clamping plate 65 to lift and lower, but the ferrule 4 is not completely locked, so that the lower arc clamping plate 65 is not completely locked. The clamping surfaces of the plate 61 and the upper arc-shaped clamping plate 65 are adapted to the ferrule 4 that needs to be connected. At this time, the guiding and traction of the lower arc-shaped clamping plate 61 and the upper arc-shaped clamping plate 65 can be used, It is ensured that the ferrule 4 is docked with the optical cable 8 more stably and accurately.

Embodiment 2

[0037] Example 2, as Figure 2-Figure 5As shown, when the ferrule 4 is guided into the access channel 7 along the structure around the tapered opening 5, at this time, two sets of pressing rods 38 can be pressed in advance to drive the connecting plate 35, the positioning block 34 and the spring 36 to compress, so as to promote the positioning The block 34 is received into the conical sleeve 32. After the conical sleeve 32 is engaged and sealed with the conical opening 5, then the pressing of the pressing rod 38 can be released, so that the elastic restoring force of the positioning block 34 can contact the inner wall of the conical opening 5. Contact, and then along with the overall rotation of the tapered sleeve 32 , the two sets of positioning blocks 34 are automatically matched with the engaging positions of the positioning holes 33 for locking and positioning, which increases the convenience of operation and the fixing effect of the structure.

Abstract

The invention discloses a passive optical modem optical fiber access device, which includes an access sleeve and a ferrule, a cross-shaped frame is fixedly connected to one end outside the access sleeve, and a cone is fixedly connected to the edge of one side of the access sleeve. The inner side of the access sleeve is provided with an optical cable, and the inner side of the access sleeve close to the optical cable is provided with a corresponding access channel, and the ferrule extends to the inner side of the access channel and connects with the optical cable. Plug-in adaptation; the present invention cooperates with the structure of the sealing positioning mechanism, the tapered mouth and the access channel, so that a guide channel is formed on the butt joint surface of the ferrule and the optical cable, and the channel and the tapered sleeve and the cone at the entrance can be used The guiding fit of the shaped opening allows the access operation of the optical fiber to obtain auxiliary correction and positioning effects, and promotes the complete engagement of the butted optical fiber under the structure of the tapered sleeve and the tapered port, ensuring the perfect connection of the ferrule and the optical cable .

Description

technical field [0001] The invention relates to the technical field of optical fiber access devices, in particular to a passive optical modem optical fiber access device. Background technique [0002] Optical modem, also known as single-port optical transceiver or optical modem, is a three-piece optical fiber transmission equipment developed for special user environments. The device adopts large-scale integrated chip, simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function, optical fiber access device, which is a device for detachable connection between optical fibers and optical fibers. The two end faces of the fiber are precisely butted together, so that the light energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. [0003] When the current optical fiber is actually connected, the device generally wraps the optical fiber ferrule and the optical cable ...
