Description

[Technical Field] The present invention relates to a fixing clip for a composite optical cable connector,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a composite optical cable connector, and more particularly, to an anchor assembly to a composite optical cable and a fixing clip capable of firmly fixing the ashing body.

Cable used for signal transmission of broadcasting camera equipment and A / V equipment is a composite optical cable in which an optical fiber and a copper wire are provided as a single cable. In addition, a composite optical cable connector is installed on both ends of the composite optical cable for connection between these devices. Referring to FIG. 3, a composite optical cable generally includes an optical fiber, a control signal line, a power line, and a strength member. Referring to FIG. 2, the conventional composite optical cable connector includes a plurality of members for connecting the signal lines and the like, and particularly includes an anchor coupled with a strength member of the cable to enhance the tensile force of the cable . An anchor firmly supports a strength member and is tightly coupled to an earthing body to be fixed to a groove formed in an insert carrier so that a composite optical cable is fixed to a connector, Prevent movement. In addition, in order to prevent movement due to generation of clearances between the optical fibers and the signal lines, epoxy is filled and fixed at the joint portion between the anchor and the sinking body inside the connector, thereby protecting the optical fiber and the like. In this process, if the motion occurs before the epoxy is cured enough to fix the anchor to the digging body, it will not be fixed, and if there is additional motion, the gap will be generated and if it accumulates, the optical fiber may be damaged. Figure 8 is an actual example of a clearance between an anchor and an angled body. The upper picture of FIG. 8 shows the normal coupling, but the lower picture shows the clearance between the anchor and the ingning body. If such a clearance is generated, it can not be fixed to the groove formed in the insert carrier, and therefore, the connector can not be reassembled when the part is repaired, so that the entire connector needs to be cut and replaced.

On the other hand, if the amount of epoxy filling is excessive, disassembly for repairing the connector becomes difficult and the entire connector must be replaced. Therefore, it is necessary to fix the anchor and the rigging body rigidly.

Respectively.

FIG. 1 is a perspective view of a fixing clip according to the present invention, viewed from another direction, and FIGS. 2 and 3 are sectional views of a composite optical cable and the overall configuration of a connector.

Referring to FIGS. 1 to 3, the composite optical cable 300 includes a reinforcing member 310. The reinforcing member 310 is for reinforcing the tensile strength of the cable and for a rigid connection between the composite optical cable 300 and the connector 200. The reinforcing member 310 is engaged with the anchor 210 of the connector 200 and the anchor 210 is fixed to the groove formed in the insert carrier in close contact with the engaging body 220 of the connector 200 The composite optical cable 300 is fixed to the connector 200 to prevent the movement of the signal lines.

The fixing clip 100 according to the present invention can secure the connection between the anchor 210 and the arching body 220 to prevent the optical fiber from being damaged and also to partially repair the faulty portion even when repairing the connector 200. [ The fixing clip 100 can be applied to the coupling of the anchor 210 with the arching body 220 and the anchor 210 in the coupling of the conventional connector 200 and the composite optical cable 300.

The fixing clip 100 according to the present invention includes a coupling part 110 which is tightly coupled to the upper surface of the anchor 210 and a support part 120 which is bent at both sides of the coupling part 110 and is closely contacted with the side surface of the anchor 210. [ And a fixing pin 130 extending from the supporting part 120 in one direction. The reinforcing member passage hole 111 through which the reinforcing member 310 of the composite optical cable 300 can pass is formed in the coupling portion 110. The fixing pin 130 includes a bent portion 131 that is inserted into the inside of the arching body 220 and then bent to closely contact the anchor 210 with the arching body 220.

The reinforcing member passing hole 111 allows the reinforcing member 310 to pass therethrough because the fixing clip 100 coupled with the anchor 210 can prevent the right and left slippage.

It is preferable that four fixing pins 130 are provided, but it is apparent that the fixing pin 130 will not be difficult to implement the present invention if two or more fixing pins 130 are provided.

The bent portion 131 is fixed to the crimping ring 230 which is bent outward from the inside of the arching body 220 and coupled to the outside of the arching body 220.

FIG. 4 is a view showing the connection between the fixing clip, the anchor and the digging body according to the present invention, FIG. 5 is a flowchart showing the combination of the fixing clip, the anchor and the digging body according to the present invention, And the bent portion of the first embodiment.

4 to 5, the reinforcing member 310 of the composite optical cable 300 is inserted into a hole formed at the center of the anchor 210 and is fastened to the anchor 210 by fastening the fastening screw formed on the side of the anchor 210 210). The anchor 210 is fitted in the engaging body 220 and is fixed to the groove formed in the insert carriers, thereby fixing the composite optical cable to the connector, thereby preventing the movement of the signal lines.

The fixing clip 100 is installed on the upper side of the anchor 210 and the reinforcing member 310 is exposed through the reinforcing member passing hole 111 through the anchor 210 and a predetermined length. This makes it possible to prevent the fixing clip 100 from sliding to the left and right of the anchor 210. The engaging portion 110 of the fixing clip 100 is tightly engaged with the upper surface of the anchor 210 and the supporting portion 120 is tightly engaged with the side surface of the anchor 210. The fixing pin 130 passes through the inside of the engaging body 220 so that the bent portion 131 at the end of the fixing pin 130 is exposed to a lower side than the lower end of the engaging body 220 by a predetermined length or more.

6, the bent portion 131 is bent outwardly of the engaging body 220 to fix the anchor 210 to the engaging body 220. Specifically, the bent portion 131 is coupled to the outside of the engaging body 220 The anchor 210 and the engaging body 220 are firmly coupled by the fixing clip 100 by fixing the bent portion 131 of the crimping ring 230.

7 is a graph comparing the amount of epoxy injection according to the present invention and the prior art. Referring to FIG. 7, according to the conventional method of assembling a connector on the left side, it is impossible to partially repair an epoxy because the epoxy is excessively injected to secure the anchor 210 and the engaging body 220. However, When the fixing clip is used, the amount of epoxy injection is remarkably reduced, and as a result, partial repair is possible when the connector 200 fails.

In other words, the fixing clip for a composite optical cable connector according to the present invention can firmly fix the anchor and the gashing body to prevent a gap caused by the movement of the cable, thereby prolonging the life of a composite optical cable connector such as a TV camera. Further, by using a smaller amount of epoxy than in the prior art, the radius of curvature of the optical cable inside the connector can be ensured, so that not only the optical cross section but also the power line and the data line can be partially repaired. Therefore, in the conventional technology, even if a partial failure occurs, the entire connector needs to be cut and newly made. Therefore, it is necessary to pay a high repair cost. However, the use of the fixing clip according to the present invention makes partial repair possible, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. , It is to be understood that various equivalents and modifications may be substituted for those at the time of the present application.
