Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is merely for purposes of illustration and explanation and is not intended to limit the embodiments of the present invention.

In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, and bottom" is generally used with respect to the orientation shown in the drawings or the positional relationship between the components in the vertical, or gravitational direction.

In addition, if there is a description in the embodiments of the present invention referring to "first", "second", etc., the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or can not be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Fig. 1 is a top view of a fiber optic connection interface having a spring-gated type according to an embodiment of the present invention. Fig. 2 is a front view of a fiber optic connection interface having a spring-gated structure according to an embodiment of the present invention. Fig. 3 is a perspective view of a fiber optic connection interface having a spring-gated type according to an embodiment of the present invention. In fig. 1 to 3, the patch cord may include a sprung-gated fiber optic connection interface 01, a patch interface 02, and a splice tray 03.
