Description

Ultra-thin LC plug optical module structure

Technical Field

The utility model relates to a module installation field especially relates to an ultra-thin type LC plug optical module structure.

Background

In the military or other industrial control field, there are very demanding requirements on the installation volume of the module. In order to meet the requirement, a miniSFF outline packaging module structure appears, the size of the miniSFF outline packaging module structure is only half of that of an optical module of a traditional SFP or SFF outline packaging structure, the existing miniSFF packaging mainly comprises an LC plug-in type and a tail fiber type, the LC plug-in type is more convenient to use, but the thickness of the module is basically consistent with the traditional packaging forms of the original SFP and the SFF due to the limitation of an LC optical socket, and therefore the use requirement of a device with a harsh requirement on the thickness of the optical module cannot be met.

Disclosure of Invention

The utility model aims at the above-mentioned problem, provide an ultra-thin type LC plug optical module structure of simple structure, convenient to use.

In order to realize the purpose, the technical scheme of the utility model is that:

an ultrathin LC plug-pull optical module structure comprises an optical module shell, wherein the optical module shell comprises an upper cover and a lower cover, the upper cover and the lower cover are connected in a buckling mode to form a rectangular cavity with one open end, a connecting bayonet is arranged on the left side and/or the right side of the open end of the rectangular cavity, and the rectangular cavity is detachably connected with an elastic buckle arranged on the outer side of an optical fiber jumper through the connecting bayonet; the middle part of the rectangular cavity is provided with an optical transceiver, and the front end of the optical transceiver is provided with a connecting hole and is spliced with the front end of the optical fiber jumper through the connecting hole; the rear end of the optical module shell is provided with an electrical interface pin header, and the rear end of the optical transceiver is connected with the electrical interface pin header through a line.

Furthermore, the number of the rectangular cavities is two, the opening ends of the two rectangular cavities are symmetrically arranged, the left side of the opening end of one rectangular cavity is provided with a connecting bayonet, and the right side of the opening end of the other rectangular cavity is provided with a connecting bayonet.

Further, the upper cover is a metal or plastic upper cover, and the lower cover is a metal or plastic lower cover.

Furthermore, a round support is integrally formed at the bottom end of the lower cover.

Compared with the prior art, the utility model has the advantages and positive effect be:

the design that the bayonets are arranged on the left side and the right side of the rectangular cavity body enables the elastic buckles on the outer side of the optical fiber jumper to be transversely arranged to be clamped with the bayonets when the optical fiber jumper is installed, effectively reduces the overall thickness of the optical module, and provides a feasible scheme for devices which need smaller thickness and need to use LC plug-in optical interfaces; on the other hand, the utility model discloses both can design and be used for realizing two-way transmission for a LC plug interface, also can design and be used for realizing two-way transmission for two LC plug interfaces, both have possessed the characteristics that reduce optical module thickness equally, and the use of giving people has brought very big facility.
