Description

Connecting Box for Optical Cable {Connecting box for optical cable}

The embodiment relates to an enclosure for an optical cable.

The data transmission method using optical fiber is widely used in the communication field because it is much superior in the transmission rate and the quality of the transmitted signal than the conventional method of transmitting data using the electric signal.

A general optical fiber has a disadvantage in that the transparent dielectric material such as quartz glass or plastic is made by elongating and pulling the dielectric material so that the strength of the material is relatively weak. For this reason, the outer surface of the optical fiber is covered with a buffer cover or the like to be formed into a cable shape.

When a part of the introduced optical fiber is connected to the optical fiber of the optical adapter and is distributed to the transmission apparatus of the subscriber in the short distance, the remaining optical fibers of the optical cable are connected to the optical cable And is distributed to the transmission apparatus of the subscriber at a long distance.

Korean Unexamined Patent Application Publication No. 10-2010-0024599 (published on Mar. 03, 2010, hereafter referred to as the present document) discloses a connection body for an optical cable. The connection sleeve for optical cables in this document includes a housing into which an optical cable is led, and trays and ports for connecting optical cables are provided inside the housing.

The second lid 220 is formed to have a constant height and is configured to abut the lower surface of the second lid 220 so that the inner surface of the second lid 220 faces the lower surface of the second lid 220, Forming a connection or accommodation space,

7 is a side view of the second housing portion.

7, the adapter 230 protrudes from the bottom 211 of the second body 210 in the height direction of the second body 210 (z-direction in FIG. 8). The connector 231 mounted on the adapter 230 is located at a position spaced apart from the bottom 211 of the second body 210 by a predetermined height. This is for securing a working space under the optical cable as shown in FIG. 8A when the optical cable is connected to or disconnected from the connector 231.

The height H1 of the side wall 216 may be smaller than the height H2 of the front wall 217. [ The height H1 of the side wall 216 is a distance from the lower surface 211a of the bottom portion 211 of the second body 210 to the side wall 211b of the second body 210 in the height direction of the second body 210 And the height of the upper portion of the upper portion 216 to the upper end. The height H2 of the front wall 217 is a distance from the bottom surface 211a of the bottom portion 211 of the second body 210 to the front wall 211b in the height direction of the second body 210 (217).

The height H1 of the side wall 216 should be smaller than the height H3 of the connector 231 of the adapter unit 230. [ This is for securing a working space of the optical cable that can enter from the side of the second body 210 as shown in FIG. 7A. When the side wall 216 is raised, the operator's hand is caught by the side wall 216 when the optical cable is connected to or disconnected from the terminal 231, thereby interfering with the operation. Here, the height H3 of the terminal 231 of the adapter unit 230 refers to the height of the bottom portion of the second body 210 (refer to z in FIG. 8) 211 from the lower surface 211a to the lower end of the terminal 231. [

The height H2 of the front wall 217 is larger than the height H1 of the side wall 216 and smaller than the height H4 of the adapter 230.

A cutout 221a may be formed in the front wall 221 of the second lid 220 in correspondence with the front wall 217 of the second housing 200. [ The incision 221a takes into consideration the position of the fixing part 240 disposed on the front wall 217 of the second housing part 200. [

The fixing part 240 is disposed on the front wall 217 of the second housing part 200 and serves to fix an optical cable connected to the connector 231 of the adapter part 230.

Fig. 8 is a view showing the fixing portion, and Fig. 9 is a view showing the width of the opening of the locking hole of the fixing portion.

Referring to FIGS. 8 and 9, the fixing portion 240 includes a plurality of locking grooves 241. The plurality of latching grooves 241 may be disposed at a predetermined interval along the width direction of the second housing unit 200 (x-axis direction in FIG. 9). The position of each of the latching grooves 241 may correspond to the position of the connector 231 of the adapter unit 230. The latching groove 241 is recessed from the upper surface of the front wall 217, and an inlet having a narrower width than the internal space can be formed. An optical cable connected to the connector 231 of the adapter unit 230 is inserted into the locking groove 241. The width of the entrance of the locking groove 241 is formed to be slightly smaller than the outer diameter of the optical cable,

Meanwhile, each of the latching grooves 241 may include a first hole 241a and a second groove 241b. The first hole 241a and the second groove 241b may be arranged along the longitudinal direction of the second housing unit 200 (x-axis direction in FIG. 9). The first hole 241a is disposed closer to the adapter portion 230 than the second groove 241b with respect to the longitudinal direction of the second hermetically-packed portion 200 (x-axis direction in FIG. 9). The width W1 of the inlet of the first hole 241a may be smaller than the width W2 of the inlet of the second groove 241b. That is, the hooking grooves 241 have the advantages of increasing the fixing force of the optical cable by arranging the mouths having different widths. Particularly, in fixing an optical cable having an elliptical cross-sectional shape other than an optical cable having a circular cross-sectional shape. The configuration of the latching grooves 241 greatly increases ease of operation.

As described above, the optical terminal according to one preferred embodiment of the present invention has been specifically described with reference to the accompanying drawings.

It is to be understood that one embodiment of the invention described above is to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description. It is intended that all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
