The present invention relates to an anti-loosening coupling combination and a terminal combination using the same, and more particularly, after the coupling between terminals including a connector coupling between RF coaxial cable terminals for mobile communication, the time elapses due to wind or vibration of the underground space. The present invention relates to an anti-loosening coupling combination and a terminal combination using the same to prevent the coupling or fastening from being loosened.

In general, the coupling of the terminal is made by fastening the coupling mainly depending on the screw coupling as shown in Figure 1 in addition to the male and female coupling between the connectors.

Therefore, the connection part installed in the underground tunnel is transmitted to the two coupling parts by the vibration of the traveling of the subway, so that the fastening part becomes loose over time.

The loosening of these fasteners will seriously affect the electrical characteristics of the connector, affect the quality of the equipment connected to the two lines, and consequently lead to user complaints. Therefore, there is an urgent need to develop a fastening method that can be easily disconnected when necessary without being released from the fastening parts of the two connection terminals without being affected by vibration.

Through this, when the terminal is fastened, the external housing is first engaged with each other in a state in which the external housing is retracted backward as shown in FIG. 2, and after the coupling is completed, the external housing as shown in FIG. 10 after the coupling is completed. By advancing the polygonal fixture of the opposite terminal and the groove of the outer housing is combined so that no further rotation occurs, the elastic member is to keep pushing the outer housing so that this coupling is not removed.

The coupler is included in all of the various types of coupling having a known coupling, of course, and preferably coupled by a rotary coupling as a specific example of this BNC cable terminal connection and the form as shown in Figure 1 This also applies to the coupling sphere of.

To this end, the coupling 30 should have a first support part 33 for supporting the elastic member 40 in the coupling direction of the both terminals 10 and 20 on the outer circumferential surface thereof, and specific examples thereof will be described with reference to FIGS. As shown in FIG. 10, the first support part 33 of the outer circumferential surface may have a first catching jaw 33 formed of a step in the circumferential direction.

In addition, as the elastic member 40, various elastic members for generating a known elastic force may be used. The elastic member 40 may include a coil spring, a leaf spring, a rubber material, and the like. A spring (coil spring) wound around the outer circumferential surface is good in terms of securing elasticity, durability, and assembly.

In addition, the coupling 30 has a key moving in the movable slot 53 to fix the external housing 50 at each position when the external housing 50 is advanced or retracted as described above. That is, the key is provided with at least one protrusion protruding higher than the first support portion to the outside of the outer peripheral surface on the upper side of the support surface of the first support portion.

In addition, since the elastic member 40 should be configured to be included in the outer housing 50 in order to operate properly without being separated, the first cylindrical portion 52 including the elastic member 40 therein is provided. do. In addition, as described above, the key 34 must be moved and fixed so that the outer housing can be moved relative to the coupling, so that the opposite side of the side having the second support 51 and the first cylindrical portion 52 ( The key 34 is provided with a second cylindrical portion 54 having a moving slot 53 for fixing the key 34 in the longitudinal direction of both terminals. Also, in order to prevent the connection from being released by vibration or the like due to the final coupling between the two terminals, the polygonal fastener 61 of the terminal coupled to the inner circumferential surface of the end of the second cylindrical portion 54 side by side in parallel with the coupling direction of the two terminals is connected thereto.

At this time, the edge of the polygonal fixture of the second terminal is inserted between the grooves of the outer housing so that no further coupling rotation is made. A cross-sectional view of the form in which the fixing is completed is as shown in FIG. 10, and an external view is as shown in FIGS. 8 and 9. In addition, in the case of Figure 11 is a cross-sectional view of the cross section A-A of Figure 8 is a view showing how the corner of the polygonal fixture is fixed to the groove of the outer housing.

After the fastening is completed through the above process, if necessary, as shown in FIGS. 12 and 13, the outer housing is retracted backward (the first terminal side), and then fixed with a slot for movement and coupling in the direction of the arrow shown. The fastening can be disengaged by rotating the assembly.
