Abstract
The utility model relates to a packaging device for a modular programmable logic controller (PLC) optical splitter, which comprises a rubber seat. The rubber seat is provided with a cavity for receiving a PLC optical assembly. The inner side and the bottom of the cavity are provided with limit units for the PLC optical assembly. The two ends of the rubber seat are provided with structures for optical fibers led out of the PLC optical assembly to pass through. According to the technical scheme of the utility model, optical components packaged in the device are well protected during impact. Meanwhile, optical components are prevented from touching the inner wall of the device due to the adoption of the limit units designed for optical components and arranged inside the device, so that the optical indexes of the optical components are not influenced at all. The packaging device also has the advantages of simple structure, simple preparation technology, low cost and the like.
Description
Technical field
The utility model relates to a kind of modular PLC optical branching device packaging system, belongs to optical fiber communication attachment technique field.
Background technology
Existing modular PLC optical branching device is when packaging optical device; all adopt optical device is bonded in lower steel pipe centre position with glue; after input end plug and output terminal plug are clamped respectively optical device two ends optical fiber; use glue that plug is bonded in lower steel pipe two ends; and input end plug and output terminal plug top point glue on the drawbacks such as steel pipe is bonding lives, and this encapsulating structure exists that production efficiency is low, material cost is high, sun adjuster spare protective value is poor when being hit.
Summary of the invention
The purpose of this utility model aims to provide a kind of modular PLC optical branching device packaging system, and the protective value of sun adjuster spare is good when being subjected to external impacts, and cost is low.
The technical solution of the utility model: a kind of modular PLC optical branching device packaging system, comprise a rubber base, described rubber base has the cavity that holds the PLC optical module, inboard and the bottom of described cavity is provided with the stop means of PLC optical module, and described rubber base two ends are provided with the structure that optical fiber that confession PLC optical module draws passes through.
Described stop means is in two inboards and the bottom of rubber base cavity raised line to be set respectively.The raised line of cavity two inboards can guarantee that optical device does not touch the medial surface of cavity, and the raised line of bottom can guarantee that optical device does not contact the bottom.
As preferably, the raised line of rubber base cavity two inboards and the raised line of bottom are more than two.Raised line is more, and protective value is better.And the groove that forms between the raised line of bottom can be used as a glue position, has avoided glue from overflowing.
The structure that described optical fiber of drawing for the PLC optical module passes through is groove or through hole.
Advantage of the present utility model: utilize the characteristic of rubber elastic material, good to being encapsulated in its inner optical device protective value when being hit; The position limiting structure that optical device is arranged guarantees that optical device can not cause affecting optical index because touching inwall; The structure of restricted fiber position is avoided optical fiber pulling optical device when being subjected to external force, cause the device abutting edge impaired; Setting has a structure of glue position, has avoided glue from overflowing, uses more convenient and quicker.The utility model also has the characteristics such as simple in structure, that preparation technology is simple, cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation under the utility model use state.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of modular PLC optical branching device packaging system, comprise a rubber base, described rubber base has the cavity that holds the PLC optical module, and described cavity two inboards are respectively equipped with three and two raised lines, does not touch the medial surface of cavity to guarantee optical device, described cavity bottom is provided with two raised lines, to guarantee that optical device does not touch the bottom of cavity, the groove that forms between two raised lines of bottom also is a glue position simultaneously, has avoided glue from overflowing.Described rubber base two ends are provided with the groove that the optical fiber of drawing for the PLC optical module passes through, and groove has position-limiting action to optical fiber simultaneously, can avoid optical fiber pulling optical device when being subjected to external force and cause the device abutting edge impaired.
During use, first-selection is put glue in the groove of the raised line formation of bottom, and in the rubber base of then optical device that is coupled being packed into, input end fiber and output terminal optical fiber are drawn in the groove at rubber base two ends respectively.
