[0031] Referring to Figure 1-7 As shown, a protective installation component for installing a cable harness includes a bellows 7, a first connection part, and a second connection part. The bellows 7 is deformable and is made of a special stainless steel material, which is used to prevent instantaneous flame from damaging the internal cables, and the material is soft and can be manually bent. The first connection part and the second connection part are respectively connected to both ends of the bellows 7. The first connection part includes a pipe fitting A 8, a pipe fitting B 9, a connecting pipe A 10, and a connecting collar A 13. The pipe fitting A 8 is connected to the bellows 7. The pipe fitting A 8 is connected to the pipe fitting B 9 and there is an included angle between them to form a bent shape. The pipe fitting A 8 and the bellows 7 can be connected by welding, and the pipe fitting A 8 can be connected to the pipe fitting B 9 by welding. A convex key 14 is provided on the inner peripheral surface of the pipe fitting B 9, and a rotating groove 15 that cooperates with the convex key 14 is provided on the outer peripheral surface of the connecting pipe A 10. The rotating groove 15 is a semi-ring on the connecting pipe A 10, forming a 180° rotating space. During assembly, the convex key 14 of the pipe fitting B 9 is aligned with the rotating groove 15 of the connecting pipe A 10. The pipe fitting B 9 is sleeved outside the connecting pipe A 10 and is limitedly connected through the convex key 14 and the rotating groove 15. The connecting collar A 13 is sleeved outside the connecting pipe A 10, and the end of the connecting collar A 13 is rotatably clamped with the connecting pipe A 10, and the connecting collar A can rotate.

[0032] In this embodiment, the bellows 7 can protect the cable externally. By using the bendability of the bellows 7 itself, one end of the bellows 7 connected to the second connection part meets the usage requirement of being bendable. And by using the convex key 14 and the rotating groove 15, after the bent end is inserted and fixed with the connector 1, the bellows 7 at the bent pipe end can be limited to rotate 180 degrees. Thus, the technical problems to be solved by the present utility model can be solved.

[0033] Further, the included angle between the pipe fitting A and the pipe fitting B 9 is set to 90 degrees to form a right-angle elbow.

[0034] The second connecting part includes a connecting pipe B 6 and a connecting collar B 3, and the connecting collar B 3 is sleeved outside the connecting pipe B 6. Docking gear rings 16 are provided at the ends of the connecting pipe A 10 and the connecting pipe B 6 respectively for limit meshing with the docking gear rings on the corresponding connectors 1.

Therefore, in this embodiment, a sealing snap ring 11 and an O-ring 12 are provided between the pipe fitting B 9 and the connecting pipe A 10. Both the sealing snap ring 11 and the O-ring 12 are used to prevent water at the front end of the pipe fitting B 9 from entering, as Figure 5 shown in the figure.

[0036] External connection threads are provided on the outer circumferential surfaces of the connecting collar A 13 and the connecting collar B 3 for connecting with the corresponding connectors 1. Preferably, in order to achieve reliable sealing and reliable waterproofing, sealing grooves 4 are also provided on the inner circumferential surfaces of the connecting collar A 13 and the connecting collar B 3, and sealing rings are provided in the sealing grooves 4. And two sealing grooves 4 are respectively provided on the connecting collar A 13 and the connecting collar B 3. One of the sealing grooves and the sealing ring cooperate to prevent water at the front end of the connecting collar from entering, and the other sealing groove and the sealing ring cooperate to prevent water at the rear end of the connecting collar from entering. As Figure 4 shown in the figure. A total of 4 sealing grooves 4 are provided.
