Fig. b) is a partially enlarged view of one connector and another connector, and FIGS. 6 (a) and 6 (b) are operational views of two connectors.

First, as described above, the caterpillar 1000 may be formed of a plurality of connectors 1100.

4A and 4B, the connector 1100 may include a first side plate 1110, a second side plate 1120, and a connecting portion 1130. [

Here, the periphery of the coupling member 1100 is circular, and the front end face of the second contact groove 1122 may also be formed in an arc shape. This is for the purpose of forming such that when one connector 1100 and another connector 1100 are coupled, they can rotate with each other.

The first side plate 1110 may be formed on one side of the connector 1100 and the second side plate 1120 may be formed on the other side of the connector 1100.

At this time, the first and second side plates 1110 and 1120 may be formed identically.

Specifically, the first and second side plates 1110 and 1120 may include a first contact groove 1121, a second contact groove 1122, an interference fit protrusion 1123, and a interference fit hole 1124 .

The first contact groove 1121 may be formed to have a predetermined depth from the outer surface of the front end portion to the inner surface and open at the front end side.

The second contact groove 1122 may be formed such that the rear end side is opened and the rear end side is folded to a predetermined depth from the inner side surface to the outer side surface.

The interference fit projection 1123 is formed at the end of the first contact groove 1121 and the interference fit hole 1124 can be formed at the end of the second contact groove 1122.

At this time, the outer circumferential surface of the interference fit projection 1123 may be formed in an uncut form.

That is, as shown in FIG. 5 (a), when one connector 1100 and another connector 1100 are to be coupled, a first contact groove 1121 formed in one connector 1100 And the inner surface of the second contact groove 1122 formed in the other coupling body 1100 correspond to the outer surface of the coupling body 1100 and the interference fit protrusion 1123 formed in one coupling body 1100, Fitting hole 1124 formed in the coupling member 1100 so that one coupling member 1100 and another coupling member 1100 are connected to each other.

Therefore, the interference fit protrusions 1123 formed on one connector body 1100 can be prevented from being separated from the interference fit holes 1124 formed on the other connector body 1100, have.

The coupling member 1100 may further include a projection 1125, a guide groove 1126, and a projection hole 1127.

The protrusions 1125 may have a predetermined gap around the circular arc of the second contact groove 1122, and may protrude partially inwardly.

At this time, the number of protrusions 1125 formed on one side of the connector 1100 is shown as three in the figure, but is not limited thereto and may include at least two or more protrusions 1125.

The guide grooves 1126 may be formed to be formed by a predetermined depth around the circular arc of the first contact groove 1121.

At this time, the corrugated shape of the guide groove 1126 is preferably formed in the same shape as the protrusion 1125 protrudes. This is because the guide groove 1126 serves to guide the movement of the protrusion 1125 when one connector body 1100 and another connector body 1100 are coupled.

A protrusion hole 1127 may be formed around the circular arc of the guide groove 1126 so that the protrusion 1125 is inserted at a predetermined interval.

The inclined surface formed at the front end of the stopper 1140 in one connector 1100 may be formed to correspond to an arc surface formed at the lower end of the rear end of the other connector 1100.

This is to limit the angle at which the plurality of connectors 1100 rotate downward.

Therefore, the stopper 1140 is formed at the intermediate portion of the connecting member 1100, so that the caterpillar 1000 can be prevented from being pivoted downward to be separated.

The inclined surface 1150 is formed at the upper end of the rear end of the connector 1100, and may be formed upward toward the front end side at the rear end.

In addition, the inclined surface 1150 in one connector 1100 may be formed so as to correspond to the rear surface of the first contact groove 1121 in the other connector 1100.

This is to limit the angle at which the plurality of connectors 1100 are rotated upward.

Therefore, since the inclined surface 1150 is formed at the upper end of the connecting member 1100, the caterpillar 1000 can be prevented from rotating in the leftward direction and being separated from the caterpillar.

Thus, the caterpillar 1000 can discharge the foreign substances therein, so that the plurality of connecting bodies 1100 can operate more smoothly, and the life expectancy can be prolonged.
