[0002] The pipe clamp for automotive wire harnesses exists to fasten the automotive wire harness and fix it in the corresponding position. With the gradual popularization of automotive intelligence, the use of automotive electronic components has gradually increased. As the transmission path between electronic components, the wire harness is also more and more widely used in automobiles. The wide application of the wire harness has led to an increasingly thick diameter of the wire harness. The requirements for the direction and bonding force of fixing the wire harness to the automotive sheet metal are getting higher and higher. This has led to higher and higher requirements for the rational layout of the circuit by major vehicle manufacturers. Then, the corresponding problem has emerged: how to conveniently, quickly and firmly fix the wire harness and prevent rotation in the case of limited space resources - the double-headed pipe clamp is used in this situation. Because the pipe clamp is circular in structure, it can achieve the fixation of bundling the wire harness and corrugation in a very small space. Due to the increasingly wide range of applications, the market's requirements for the pipe clamp are also gradually increasing. It is required to have a high pull-off force and be anti-rotating after installation to prevent friction caused by contact with the sheet metal. However, due to structural limitations, ordinary pipe clamps generally have only one fixing point. When the pulling force after the wire harness swings to a certain value, the wire harness will rotate. Content of the Utility Model

[0003] Aiming at the above problems, the utility model provides a double-headed anti-rotation pipe clamp bracket for fixing wire harnesses, which has the advantages of enabling the pipe clamp to maintain a high pull-off force and preventing the wire harness from rotating at the same time.
