Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

The first embodiment is as follows:

as shown in fig. 1 to 4, the present embodiment provides an optical fiber coupler capable of aligning, including a coupler housing 100, an alignment assembly 200 and a fixing assembly 300, wherein the alignment assembly 200 includes recessed slots 210 symmetrically formed through two sides of the coupler housing 100, and alignment clips 220 mounted inside the recessed slots 210 in a matching manner, the alignment assembly 200 further includes first springs 230 disposed inside the recessed slots 210 and disposed at the upper ends of the alignment clips 220, and covering sleeves 240 disposed at two sides of the center of the coupler housing 100 in a sleeving manner, the recessed slots 210 are T-shaped rectangular column structures, and the alignment clips 220 include an arc clip at the front end and a T-shaped rectangular column at the rear end.

Specifically, the alignment clamp 220 symmetrically installed at the two ends of the coupler housing 100 can perform clamping coaxial alignment on the optical fiber tubes inserted into the adaptor body 120 at the two sides under the shielding of the outer shielding sleeve 240 when the optical fiber tubes at the two sides are connected, so as to realize coaxial alignment on the two sides of the adaptor body 120, and further improve the signal transmission effect when the optical fiber tubes are connected.

Example two:

on the basis of the first embodiment, as shown in fig. 5, the fixing assembly 300 includes a mounting groove 310 formed in the coupler housing 100 at the outer end of the recessed groove 210, and second springs 320 and clamping posts 330 arranged at the inner and outer ends of the mounting groove 310, the fixing assembly 300 further includes circular holes 340 formed in the outer ends of the center of the two sides of the covering sleeve 240, the clamping posts 330 are matched with the circular holes 340, and the coupler housing 100 further includes threaded connecting posts 110 disposed at the two ends and the adapter body 120 disposed at the center.
