Referring to fig. 1-4, the present invention provides an embodiment of:

railway traffic signal transmission cable, including optical cable 100, all electrical apparatus used in this application are products that can directly purchase on the market, its principle and connection mode are the prior art that technical personnel in this field are familiar with, therefore no longer describe herein, extension spring 110 extends all from the both sides of optical cable 100, extension spring 110 and the inside of optical cable 100 all link up each other and connect, one side that extension spring 110 keeps away from each other all fixedly installs connector lug 111, the top and the bottom of connector lug 111 all overlap and are equipped with spring protective housing 112, one side that two spring protective housing 112 are close to each other all has seted up two screw holes, the threaded hole of two spring protective housing 112 all runs through and installs fixed screw, through the setting of above-mentioned structure, can install optical cable 100 on the outside cable tower with extension spring 110, connector lug 111 that extend out in the in-service use, when strong air current strikes, extension spring 110 of flexible material can rock under the effect of air current and stretch out and back to just fast after the air current stops, spring protective housing 112 can be better protection extension spring 110 outside of protection in-off because current signal can effectively solve current tunnel and the problem that the easy high temperature wiring material caused the long-term fatigue and the effect of optical cable to use is cracked easily.

All fixed mounting has fixed plate 113 on connector lug 111, and the both sides of fixed plate 113 are all seted up threaded hole, and the threaded hole of fixed plate 113 all runs through and installs mounting bolt 114, and mounting bolt 114's quantity is four altogether, through the setting of above-mentioned structure, can be with connector lug 111 more firm installation on connector 115 in the in-service use, avoids connector lug 111 and connector 115 to appear unexpected separation because of outside physical factor.

One side that connector lug 111 kept away from each other all is provided with connector lug 115, the collar has all been seted up to one side that connector lug 115 is close to each other, inside all fixed mounting of collar of connector lug 115 has second magnet 118, the equal fixed mounting in one side that connector lug 111 kept away from each other has first magnet 117, first magnet 117 and the equal heteropolar of second magnet 118, first magnet 117 and second magnet 118 all adsorb each other, the equal fixed mounting in bottom of connector lug 115 has erection column 116, the equal fixed mounting of erection column 116 is on outside optical cable tower, setting through the above-mentioned structure, can dock connector lug 111 and connector lug 115 fast in the in-service use, the construction degree of difficulty of long distance optical cable 100 has been reduced.

The fixed cover in outside of optical cable 100 is equipped with lag 119, the material of lag 119 is soft rubber, the outside fixed cover of lag 119 is equipped with outside insulation cover 120, the outside of outside insulation cover 120 is provided with the one deck aerogel, setting through the above-mentioned structure, lag 119 can provide better physics protection for optical cable 100's outside in the in-service use, and the outside insulation cover 120 that scribbles the aerogel can provide better fire prevention and thermal insulation performance for lag 119 and optical cable 100.

Through the arrangement of the structure, in actual use, the top mounting plate 123 is mounted at the top end of the tunnel, so that the external support frame 121 can lift the external heat insulation sleeve 120 and the optical cable 100 together to provide support from the top end for the optical cable 100 and the external heat insulation sleeve 120.

The inside of gallows 122 is provided with the spring, through the inside spring that is provided with of gallows 122, when strong air current in the tunnel appears and assaults in actual use, the inside spring of gallows 122 can be flexible along with rocking of light cable 100 and extension spring 110, avoids appearing the fracture too early because of rigid connection between gallows 122 and the outside support frame 121.

The working principle is as follows: in practical use, the length of the optical cable 100 is determined according to the distance between stations and the length of a tunnel, then the connectors 111 on both sides of the optical cable 100 are quickly mounted and abutted on the connectors 115 through the first magnet 117 and the second magnet 118, the fixing plates 113 and the connectors 115 are screwed by the mounting bolts 114, the fixing plates 113 are fixed on the connectors 115, then the connectors 115 are mounted on the cable towers through the mounting posts 116, the number of the external support frames 121 is determined according to the length of the optical cable 100, the external support frames 121 are sleeved outside the external insulation sleeves 120, the top mounting plate 123 is fixed at the top end of the tunnel, finally the spring protection shells 112 are sleeved on the top ends and the bottom ends of the extension springs 110 through the four-piece spring protection shells 112 and the eight screws, and then the installation of the optical cable 100 is finished.

When strong airflow occurs due to high-speed driving of a subway in a tunnel where the optical cable 100 is installed, the extension spring 110 and the hanger 122 can stretch and retract continuously and shake until the strong airflow disappears, the extension spring 110 and the hanger 122 can quickly return to the original position under the action of elastic force, the extension spring 110 is used for changing rigid connection between the connector lug 111 and the optical cable 100 into flexible connection, the hanger 122 is used for changing the rigid connection between the top mounting plate 123 and the external support frame 121 into flexible connection, and therefore the optical cable is not broken due to fatigue of materials even when being impacted by the strong airflow for a long time, the top mounting plate 123 and the external support frame 121, and the optical cable 100 and the connector lug 111 are used for prolonging the service lives of the optical cable 100 and the external support frame 121.

In this case, the lengths of the optical cable 100 and the extension spring 110 are not limited, and the number of the external support frame 121, the hanger 122 and the top mounting plate 123 is not limited, and the lengths and the number should be selected according to actual mounting requirements.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore 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, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
