Abstract
The utility model relates to an optical fiber connecting device and discloses an inserting core base for a single-core optical fiber connecting plug. The inserting core base comprises a hollow core rod and a tubular joint, and one end of the tubular joint is connected with the hollow core rod. An inserting core with the diameter as 2.5 mm can be inserted into the inserting core base directly so that the inserting core base can be matched with the existing device in our country. The inserting core base is low in cost and convenient to install, debug and maintain. The size of the inserting core base is reduced, and machine room capacity is improved under the condition of the same size as the similar products.
Description
Technical field
The utility model relates to optical fiber splicing device, is specifically related to a kind of lock pin seat for single-core fiber attachment plug.
Background technology
Three major companies of existing domestic telecommunication, movement, UNICOM adopt the coupling arrangement of single core list adapter to carry out signal conversion, and single core list is joined and existed volume large, can't expand jumbo shortcoming with the rack of volume.The external product that adopts West Europe, Japan to produce although can reduce volume, adopt φ 1.5mm lock pin, and this coupling arrangement cost is high, can't mate with domestic existing equipment simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of lock pin seat for single-core fiber attachment plug, and cost is low, can mate with existing equipment, can with the situation of like product equal volume under, improve the machine room capacity.
In order to achieve the above object, the utility model has following technical scheme:
A kind of lock pin seat for single-core fiber attachment plug of the present utility model comprises hollow core bar, tubular configured joint, and an end of described tubular configured joint is connected with hollow core bar.
Wherein, the end of described hollow core bar is provided with round taper hole, and this round taper hole is used for the grafting bare fibre, and the diameter of bore of described tubular configured joint is less than 2.5mm.
Wherein, described tubular configured joint and hollow core bar be spirally connected, bonding, or described tubular configured joint and hollow core bar are structure as a whole.
The utility model has the advantage of:
1. the utility model can directly access the lock pin of φ 2.5mm, therefore, can mate with domestic existing equipment, so cost is low, install, and debugging, easy to maintenance.
2. the utility model has reduced volume, can with the situation of like product equal volume under, improve the machine room capacity.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
In figure: 1, hollow core bar; 2, tubular configured joint.
Embodiment
Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Referring to Fig. 1, a kind of lock pin seat for single-core fiber attachment plug of the present utility model, formed by hollow core bar, tubular configured joint, one end and the hollow core bar of described tubular configured joint are spirally connected, the end of described hollow core bar is provided with round taper hole, this round taper hole is used for the grafting bare fibre, and the diameter of bore of described tubular configured joint is less than 2.5mm.
As mentioned above, just can realize comparatively fully the utility model.The above is only comparatively reasonably embodiment of the present utility model; protection domain of the present utility model includes but are not limited to: this, and those skilled in the art is any to be included within the utility model comprises scope based on unsubstantiality sex change change on technical solutions of the utility model.
