Cables are externally protected iron cables, which are widely used in brakes, throttles, shifting, etc. of automobiles, motorcycles, ships, airplanes, etc. The cable specifically includes a cable sheath, a cable core placed in the cable sheath relative to the cable, and a core connector disposed at both ends of the cable core for mating with other structures. Specifically, taking the door lock of the automobile as an example, the outer door handle is generally connected with the lock body by a cable, and the cable and the lock body are both disposed inside the door sheet metal, and the door lock is opened by pulling the outer door handle to pull the cable lock. However, since the cable is a flexible member, and the interior space of the door is relatively large with respect to the cable, when the car is in the process of running, when the bump or the steering occurs, the cable is easily swayed, and even the periphery The interference of the parts affects the normal operation of the brakes. In addition, the cables will produce a sound during the shaking process, which greatly reduces the user's driving comfort.

On the other hand, the replacement of steel with aluminum has gradually become an industry trend, and has begun to be applied in some high-end vehicles. However, since the stamping formability of the aluminum material is inferior to that of the steel sheet, the punching depth of the inner panel of the side door is also smaller, so that the space for placing the cable becomes smaller, which puts forward higher requirements for the arrangement of the pull-out line.

In order to solve the problem that the cable is swaying during the driving process, the current solution is to set a foam tube on the cable protection tube, and the foam tube can effectively reduce the vibration generated by the collision with other parts when the cable is shaken, but This solution does not fundamentally solve the problem of noise generated by the cable. In addition, since the press formability of the aluminum material is inferior to that of the steel sheet, the punching depth of the inner panel of the side door is also smaller, so that the space for placing the cable becomes smaller, so that the method of arranging the foam tube on the cable sheath is occupied.
