Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an easily-installable dust-free cable drag chain. Background Art

[0002] Combined with the attached Figure 5 As shown, in the current flat flexible trailing cable, it is usually produced by a combination of an upper protective layer, a lower protective layer, a keel, a wire clip and a keel layer. The upper protective layer and the lower protective layer are covered on the wire clip, and a keel layer is arranged in the middle of the wire clip. During the production process, the wire clips need to be sequentially installed on the keel, and then the upper protective layer and the lower protective layer are covered. Finally, the protective layer, the wire clip and the keel are fixed by fixing chucks. Multiple steps are required for assembly production. At the same time, the upper protective layer and the lower protective layer are independently arranged and need to be assembled. The upper protective layer and the lower protective layer need to be buckled, and the steps are cumbersome. Therefore, the production efficiency is not high. Content of the Utility Model

[0003] In order to overcome the disadvantage that the keel layer in the above cable affects the production efficiency, the purpose of the utility model is to provide an easily-installable dust-free cable drag chain. By adopting an integrally formed protective layer and directly buckling and fixing with a first fixing part and a second fixing part, the original keel layer structure is cancelled, which greatly reduces the production cost and also reduces the production difficulty, thereby improving the production efficiency. At the same time, the first fixing part and the second fixing part are used to fix the protective layer, and the structure is simple and convenient for production and processing, further improving the production efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: an easily-installable dust-free cable drag chain, including a protective layer and a wire clip. At least one cable is threaded through the wire clip. The protective layer is integrally formed. The protective layer covers the outside of the wire clip. The protective layer is provided with a first fixing part and a second fixing part along its length direction, and the first fixing part and the second fixing part can be mutually engaged.

[0005] In this technical solution, the protective layer is used to protect the internal circuit, prevent the internal circuit from being damaged, and ensure that the transmission function of the cable is in a normal state; the wire clip is used to install and fix the internal circuit of the easy-to-install dust-free drag chain, and the cable is used to transmit data; the protective layer is fixed through the first fixing part and the second fixing part, and the original keel layer structure is cancelled, thereby greatly reducing the production cost and at the same time reducing the production difficulty, thus improving the production efficiency; the first fixing part and the second fixing part are used to fasten the protective layer, so that the protective layer forms a sealed state along its length direction, thereby improving the protection degree of the protective layer for the internal wire clip; by adopting an integrally formed protective layer and directly fastening and fixing it with the first fixing part and the second fixing part, the original keel layer structure is cancelled, greatly reducing the production cost and also reducing the production difficulty, thus improving the production efficiency. At the same time, the use of the first fixing part and the second fixing part to fix the protective layer has a simple structure and is convenient for production and processing, further improving the production efficiency.

The protective layer 1 is provided with a first fixing portion 11 and a second fixing portion 12 along its length direction, and the first fixing portion 11 and the second fixing portion 12 can be engaged with each other.

[0039] The protective layer 1 is used to protect the internal circuit, prevent the internal circuit from being damaged, and thus ensure that the transmission function of the cable is in a normal state; the wire clip 2 is used to install and fix the internal circuit of the easily installable dust-free cable chain, and the cable is used to transmit data; the protective layer 1 is fixed through the first fixing portion 11 and the second fixing portion 12, canceling the original keel layer 7 structure, thereby greatly reducing the production cost and at the same time reducing the production difficulty, thus improving the production efficiency; the first fixing portion 11 and the second fixing portion 12 are used to fasten the protective layer 1, so that the protective layer 1 forms a closed state along its length direction, thereby improving the protection degree of the protective layer 1 for the internal wire clip 2; by adopting the integrally formed protective layer 1 and using the direct fastening and fixing method of the first fixing portion 11 and the second fixing portion 12, canceling the original keel layer 7 structure, greatly reducing the production cost and also reducing the production difficulty, thus improving the production efficiency. At the same time, the use of the first fixing portion 11 and the second fixing portion 12 to fix the protective layer 1 has a simple structure, is convenient for production and processing, and further improves the production efficiency.
