As shown, the cable has two side units, a plurality of cables are located between the two side units, and the distance between the upper unit and the lower unit of the same side unit can be adjusted by fitting a locking bolt through a sleeve and an insertion rod (since the movable block has springs up and down, the movable block is always located at the middle position of the upper unit and the lower unit regardless of the adjustment of the distance between the upper unit and the lower unit, so that the horizontal height of the cables is located at the middle position of the upper unit and the lower unit). And a plurality of cables are held between the upper clamping rod and the lower clamping rod (when the cables are installed, as the upper clamping rod and the lower clamping rod have certain elasticity and are longer, only one point of poking is needed to insert the upper insertion rod of the circular ring part of the cable into the upper insertion hole, and the lower insertion hole is inserted into the lower insertion hole), and as the upper insertion hole and the lower insertion hole are arranged in a row, a certain distance can be kept between every two cables, in addition, a certain cable which particularly needs electromagnetic shielding can be far away from other cables, as shown in fig. 1. When the cable shown in fig. 1 is placed in a drag chain, the cable is driven to bend when the drag chain bends, but the acceptable bending degree is limited because the diameter of the side units on both sides is larger (and in the bending process, although the sleeve and the inserted link are made of plastic, the buffer is provided in the bending process because of the existence of the first spring and the second spring), so that the bending degree of the cable is ensured not to be larger than that of the side units, and the cable is less prone to bend and damage. In particular, when the cable can undergo a large bend, the distance between the upper unit and the lower unit can be made small, as shown in fig. 1, when the minimum bending radius of the side unit is small, when the actual bending degree of the cable does not exceed the bending degree of the side unit, and is thus protected. The thickness of tow chain is less relatively this moment, and overall structure is compacter.
When the cable needs special protection and can only withstand small bends, as shown in fig. 2, the distance between the upper unit and the lower unit is made larger, so that the minimum bending radius of the side unit is larger, and the actual bending degree of the cable does not exceed the bending degree of the side unit, so that the cable is less bent in actual use and better protected than in the case of fig. 1. The thickness of tow chain is great this moment, and the space that occupies is bigger, but can provide better protection to the cable, and the cable is difficult to be damaged by the bending.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
