Cable guide fusion splicer

Abstract

The present invention relates to a cable guide fusion splicer, and more particularly to a cable guide fusion splicer that is detachably installed horizontally on the side of the fusion splicer and can fix the cut surface of the optical fiber in a horizontal position so that problems such as interruption of the fusion process due to the cut surface of the optical fiber being raised at the optical fiber fixing part due to sagging or bending in the longitudinal direction of a cable with one end placed on the optical fiber fixing part do not occur.

Description

[Technical Field]

[0001] The present invention relates to a cable guide fusion splicer that is detachably attached to a fusion splicer and can support a cable to be fused so that it does not sag or bend. [Background technology]

[0002] Generally, a portable optical fiber fusion splicer has a main body with a handle for easy portability, a splicing section on the upper side of the main body for fusion-splicing the ends of two optical fibers together, and a heating section for shrinking a heat-shrink sleeve tube around the fusion spliced ​​section of the optical fibers spliced ​​at the fusion splicing section. An operating section for operating the optical fiber fusion splicer is installed on the top surface of the main body. One side of the main body is equipped with a monitor for monitoring and checking the status inside the splicing section, and the other side is equipped with multiple ports such as a USB port and a power port. The main body generally has a built-in rechargeable battery for outdoor use.

[0003] With such conventional fusion splicers, if the outer diameter of the optical cable to be fused is large, the cable may sag or bend, making it difficult to align and fusion splice the optical fibers, or the end of the optical cable may not be positioned horizontally and may float upward, making it difficult to achieve stable fusion.

The present invention can be embodied and practiced in other embodiments and may be carried out in various ways. It should also be understood that the expressions and terms used herein with respect to terms such as device or element orientation (e.g., "front," "back," "up," "down," "top," "bottom," "left," "right," "lateral") are used solely to simplify the description of the present invention and do not imply or indicate that the associated device or element must have a particular orientation. Furthermore, terms such as "first," "second," and the like are used in the present specification and appended claims for descriptive purposes only and are not intended to imply or indicate relative importance or intent.

[0012] In order to achieve the above object, the present invention has the following features.

[0013] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Before that, the terms and words used in the specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted as meanings and concepts that correspond to the technical idea of ​​the present invention, based on the principle that an inventor can appropriately define the concept of a term to best describe his / her invention.

[0014] Therefore, it should be understood that the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, and that there may be various equivalents and modifications that can replace them at the time of this application.

[0015] Hereinafter, a cable guide fusion splicer according to a preferred embodiment of the present invention will be described in detail with reference to FIGS.

[0016] The cable guide 20 of the present invention is used in a field fusion splicer 100 for fusing optical fibers, and such a cable guide 20 is detachably installed on the side of the fusion splicer 100 so as to correspond to the optical fiber fixing part 10 of the fusion splicer 100, and is positioned on the same horizontal line as the optical fiber fixing part 10 and away from the ground, thereby supporting the optical cable A to be fused so that it does not sag or bend, and the fusion point of the optical cable A is positioned horizontally corresponding to the optical fiber fixing part 10, enabling stable fusion.

[0017] The detailed structure of the cable guide 20 for this purpose will be described below.

[0018] The cable guide 20 includes a base 21, an attachment line 23, a fastening portion 24, a locking portion 25, and a through portion .

[0019] The base 21 is a linear body extending from one side of the fusion splicer 100 along the longitudinal direction of the optical fiber fixing part 10, and in the present invention, is formed with a rectangular cross section, but this is a part that can be changed in various ways.

[0020] The attachment line 23 forms a longitudinal groove on the upper surface of the base 21, and is a part that seats the optical cable A in the groove. At one end of the attachment line 23 of the base 21, a protrusion 22 is formed in which both sides of the attachment line 23 protrude upward to prevent the optical cable A from coming off.

[0021] The fastening portion 24 is formed by bending downward at the front end of the base 21 and is a part that is detachably fitted into the cable guide fixing portion 11 that protrudes from the longitudinal side of the optical fiber fixing portion 10. The cable guide fixing portion 11 consists of two bolt-shaped protrusions, and the fastening portion 24 is configured with two corresponding grooves 24a that can be fitted into these protrusions from above and below and prevent them from coming off forward.

[0022] Of course, as long as the base 21 is detachably attached to one side of the fusion splicer 100, the detachable structure can be changed according to various embodiments of the user.

[0023] The locking portion 25 is a part that holds the optical cable A in the width direction to prevent it from moving and is located at the attachment line 23 on the top surface of the base 21. The locking portion 25 is composed of a cover 26 that rotates by a hinge on one side of the top surface of the base 21 and a magnet 27 corresponding to the cover 26 on the other side of the top surface of the base 21, so that the cover 26 is attached to the magnet 27 and fixed. The locking portion 25 protrudes further above the attachment line 23 from the top surface of the base 21, and its formed height can prevent the optical cable A from coming off.

[0024] The through-hole 28 is a hole formed in the front side of the base 21 so as to penetrate vertically and expose the stripped portion of the optical cable A by expanding in the vertical direction of the base 21.

[0025] In the case of the cable guide 20 having the above-described configuration, The fusion splicers 100 are detachably installed on both sides of the fusion splicer 100, and can be used simultaneously or selectively with one being used to support both of the two optical cables A to be fused.

[0026] In addition, such a cable guide 20 may be formed so that the attachment line 23 on the fastening portion 24 side is lower than the attachment line 23 on the protruding portion 22 side so that the optical cable A can be inserted stably.

[0027] In addition, in the case of the fusion splicer 100 in which such a cable guide 20 is installed, a coating stripping machine 30 capable of stripping the coating from the end of the optical cable A to be fusion spliced; a cleaning unit 40 equipped with an alcohol container capable of cleaning the stripped portion of the optical cable A; a cutter 50 capable of cutting a part of the sheath stripped portion of the optical cable A; After the fusion process of the two optical cables A to be fused is completed via the optical fiber fixing unit 10, the fusion points are wrapped in a heat-shrink sleeve and heated with a heater to protect the fusion points. A heating unit 60 is installed on the top surface, so that the processes of stripping the coating of the optical cable A → cleaning → cutting → fusion → heating can all be carried out on site using a single fusion splicer 100.

[0028] Although the present invention has been described above using limited embodiments and drawings, the present invention is not limited thereby, and it goes without saying that a person having ordinary knowledge in the technical field to which the present invention pertains can make various modifications and changes within the technical spirit of the present invention and the scope of equivalents of the appended claims.
