[0027] A fuel injector wire harness bracket, as Figure 1 and Figure 2 shown, includes:

[0028] The bracket body 10 forms a folded plate structure. The same extension sections 11 are fixedly arranged on both sides of the bracket body 10. The end of the extension section 11 is fixedly connected to the clamping section 12. The end of the clamping section 12 is fixedly provided with the bending section 13. The clamping section 12 and the extension section 11 jointly clamp and fix the wire harness;

[0029] As Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the limiting component is detachably arranged on the wall surface of the extension section 11 for clamping the wire harness. The limiting component includes a bottom plate 20, a bending part 21 and an opening 22. The bending part 21 is fixedly connected to the bottom plate 20. The bottom plate 20 is detachably connected to the extension section 11. An opening 22 is formed between the bending part 21 and the bottom plate 20. The wire harness can pass through the opening 22 and enter between the bending part 21 and the bottom plate 20. The extension section 11 is integrally formed with the bracket body 10. Both the clamping section 12 and the bending section 13 are annular structures. The clamping section 12 is bent from one end of the extension section 11 away from the bracket body 10 to form an annular rod. The bending section 13 is bent upward from the end of the clamping section 12 and abuts against the clamping section 12 to form a closed annular structure. The bottom plate 20 forms a rectangular plate structure. The bottom plate 20 is located directly below the clamping section 12. The bending part 21 is integrally formed with the bottom plate 20. The bending part 21 forms a plate with a C-shaped cross-section. An opening 22 is formed between the end of the bending part 21 and the top surface of the bottom plate 20. In the solution, through the annular clamping section 12 and the bending section 13, the closed bending section 13 can be pried up with a screwdriver so that the clamping section 12 is separated from the extension section 11, thereby facilitating the wire harness to enter below the clamping section 12 and be clamped and limited by the clamping section 12. The integrally formed bracket body 10, extension section 11, clamping section 12 and bending section 13 can be integrally formed by stamping process, which simplifies the production steps, improves the production efficiency and reduces the subsequent welding process. By setting the bottom plate 20, the rubber-bottom plate 20 can form a buffer layer below the wire harness, reducing the wear of the wire harness caused by hard contact. Cooperating with the bent and extended bending part 21, a buffer layer is formed above the wire harness, having the characteristic of wrapping and protecting the wire harness.

[0030] As Figure 5 shown, the limiting component further includes a buffer plate 24. The buffer plate 24 is fixedly installed on the top surface of the bottom plate 20 and faces the bending part 21. The buffer plate 24 is hollow inside and forms a gas storage cavity. By setting the hollow buffer plate 24, it can ensure that there is enough buffer distance between the wire harness and the bottom plate 20, ensuring the elastic clamping of the wire harness.

[0031] As Figure 5 shown, the limiting component further includes convex ribs 25. A plurality of convex ribs 25 are fixedly installed on the wall surface of the bending part 21 close to the clamping section 12. The convex ribs 25 form a rod structure with a fan-shaped cross-section. The integrally formed convex ribs 25 can abut against the inner wall of the clamping section 12. Using the clamping section 12 made of steel to reset and extrude the convex ribs 25, the bending part 21 can clamp the wire harness between the bending part 21 and the bottom plate 20 under the pushing action of the clamping section 12, ensuring the fixing effect of the wire harness.

[0032] As Figure 4 and Figure 5As shown, the limiting component further includes a plugging part 23 and a jack 26. The wall surface of the bracket body 10 is provided with the jack 26. The plugging part 23 is fixedly connected to the bottom plate 20. The plugging part 23 is plugged into the jack 26. The plugging part 23 includes a cylinder and a hemispherical body located at the end of the cylinder. The hemispherical body and the cylinder are integrally formed. The diameter of the hemispherical body is larger than that of the cylinder. The other end of the plugging part 23 is fixedly connected to the bottom surface of the bottom plate 20. The jack 26 forms a circular plate. The diameter of the jack 26 is equal to that of the cylinder. By inserting the plugging part 23 into the jack 26, when the hemispherical body of the plugging part 23 passes through the jack 26, the hemispherical body can limit the bottom plate 20 from separating from the extension section 11, realizing the installation and fixation of the bottom plate 20, which is more convenient and efficient during assembly.

[0033] The working principle of the present utility model: Insert the plugging part 23 into the jack 26. When the hemispherical body of the plugging part 23 passes through the jack 26, the hemispherical body can limit the bottom plate 20 from separating from the extension section 11, realizing the installation and fixation of the bottom plate 20. The closed bending section 13 can be pried up with a screwdriver so that the clamping section 12 is separated from the extension section 11, thereby facilitating the wire harness to enter below the clamping section 12 and be clamped and limited by the clamping section 12. The integrally formed bracket body 10, extension section 11, clamping section 12, and bending section 13 can be integrally formed by stamping process, simplifying the production steps, improving the production efficiency, and reducing the subsequent welding process. And by setting the bottom plate 20, the rubber-textured bottom plate 20 can form a buffer layer below the wire harness, reducing the wear of the wire harness caused by hard contact. Cooperating with the bent and extended bending part 21, a buffer layer is formed above the wire harness. By setting the hollow buffer plate 24, it can ensure that there is enough buffer distance between the wire harness and the bottom plate 20. The integrally formed rib 25 can abut against the inner wall of the clamping section 12. By using the clamping section 12 made of steel to reset and extrude the rib 25, the bending part 21 can clamp the wire harness between the bending part 21 and the bottom plate 20 under the pushing action of the clamping section 12, ensuring the fixing effect on the wire harness.
