[0005] To this end, we propose a split positioning structure cable duct. Utility Model Content

[0006] The utility model mainly solves the technical problem of complex molds for integrally injection molding of the main body and the connector, and provides a wire duct with a split positioning structure.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions, a split positioning structure trunking, comprising:

[0008] The main body is an injection-molded hollow block structure used for connection with the vehicle;

[0009] The mounting head is a folding plate structure that is detachably connected to the main body and is used to connect and position the vehicle. The wall surface of the mounting head is provided with positioning holes for mounting bolts, and the mounting head is locked and fixed to the main body by bolts;

[0017] The utility model provides a split positioning structure cable duct with the following beneficial effects:

[0018] 1. This split positioning structure cable duct is formed by injection molding the main body and the mounting head separately. Compared with the one-piece molding process in the existing technology, the split type has lower requirements on the mold for the injection-molded main body and the mounting head, and the mold is simpler, which optimizes the production process and helps to reduce production costs. By setting rectangular positioning holes, when installing bolts, the bolts can move in the positioning holes to achieve a floating effect. The rubber support structure realizes elastic contact between the mounting head and the vehicle, suppresses resonance between the main body and the vehicle, and thus improves the quiet effect and service life after assembly.

[0019] 2. This split positioning structure cable duct is designed by squeezing the front end into the positioning hole. After the front end passes through the positioning hole, the front and rear ends are located on the front and rear sides of the mounting head respectively. The bolt is passed through the cavity in the middle section and locked with the vehicle with the nut to achieve the connection and fixation of the mounting head. The front, middle and rear ends of the rubber one-piece molding can achieve elastic contact between the vehicle and the mounting head, reduce resonance noise, and protect the wiring harness. At the same time, only the front end needs to be squeezed for installation, which is easier and more efficient during assembly.

[0020] 3. This split positioning structure wire duct, by opening deformation grooves and extrusion grooves, forms a petal-like structure at the front end, which can produce a larger deformation amplitude to absorb vibration and achieve a better buffering effect. Secondly, by opening deformation grooves, the end of the front end forms several deformable petal-like structures, which facilitates the front end to pass through the positioning hole, thereby improving the convenience of installing the front end.

[0027] A split positioning structure trunking, such as Figure 1 、 Figure 2 and Figure 3 Shown, including:

[0028] The main body 10 is an injection-molded hollow block structure used for connection with the vehicle;

[0029] The mounting head 11 is a folding plate structure that is detachably connected to the main body 10 and is used for connecting and positioning with the vehicle. The wall surface of the mounting head 11 is provided with a positioning hole 12 for installing bolts. The mounting head 11 is locked and fixed to the main body 10 by bolts. The mounting head 11 forms a folding plate with a U-shaped horizontal cross-section. The rear wall of the mounting head 11 is provided with a through hole, and the front wall of the main body 10 is provided with a threaded hole. The bolt passes through the through hole and the threaded hole of the mounting head 11 to fasten the mounting head 11. By injection molding the main body 10 and the mounting head 11 separately, compared with the one-piece molding process in the prior art, the split type has lower requirements on the mold for the injection-molded main body 10 and the mounting head 11, and the mold is simpler, the production process is optimized, and it is beneficial to reduce production costs.

[0030] like Figure 3As shown, the positioning hole 12 is opened on the front wall of the mounting head 11. The mounting head 11 forms a notch with a rectangular cross section. The two ends of the mounting head 11 are chamfered to form arc surfaces. By providing the rectangular positioning hole 12, when the bolt is installed, the bolt can move in the positioning hole 12 to achieve a floating effect. In combination with the rubber support structure, elastic contact is achieved between the mounting head 11 and the vehicle, which suppresses resonance between the main body 10 and the vehicle, thereby improving the quiet effect and service life after assembly.

[0031] like Figure 2 、 Figure 4 and Figure 5 As shown, the support structure is arranged in the positioning hole 12 to achieve elastic contact between the mounting head 11 and the vehicle;

[0032] The supporting structure includes a front end 20, a middle section 21 and a rear end 22, and the front end 20 and the rear end 22 are fixedly connected to the two ends of the middle section 21 respectively, and the middle section 21 passes through the positioning hole 12, and the front end 20 and the rear end 22 are respectively located on both sides of the mounting head 11, and the middle section 21 forms a circular tube structure, and the front end 20 and the rear end 22 are both truncated cone structures, and the larger ends of the front end 20 and the rear end 22 are respectively fixedly connected to the two ends of the middle section 21. In this solution, by squeezing the front end 20 into the positioning hole 12, when the front end 20 passes through the positioning hole 12, the front end 20 and the rear end 22 are respectively located at the front and rear sides of the mounting head 11, the bolt is passed through the cavity of the middle section 21 and locked with the vehicle with the nut to achieve the connection and fixation of the mounting head 11, the front end 20, the middle section 21 and the rear end 22 formed in one piece of rubber can achieve elastic contact between the vehicle and the mounting head 11, reduce resonance noise, and protect the wiring harness. At the same time, it only needs to squeeze the front end 20 to install, which is simpler and more efficient during assembly.

[0033] like Figure 4 and Figure 5 As shown, the support structure also includes a deformation groove 23 and an extrusion groove 24. A plurality of deformation grooves 23 and extrusion grooves 24 are opened on the end face of the front end 20. The front end 20 forms a petal-like structure through the deformation groove 23. The extrusion groove 24 is a rectangular groove. The depth of the extrusion groove 24 is less than the thickness of the front end 20. The deformation groove 23 extends from one end of the front end 20 to the other end. A petal-like structure is formed between two adjacent deformation grooves 23. As a supplement to the above scheme, by opening the deformation groove 23 and the extrusion groove 24, the front end 20 forms a petal-like structure and can thereby generate a larger deformation amplitude to absorb vibration and achieve a better buffering effect. Secondly, by opening the deformation groove 23, a plurality of deformable petal-like structures are formed at the end of the front end 20, which facilitates the front end 20 to pass through the positioning hole 12, thereby improving the convenience of installing the front end 20.

[0034] The working principle of the present invention is as follows: the main body 10 and the mounting head 11 are separately injection molded. Compared with the one-piece molding process in the prior art, the split injection molding of the main body 10 and the mounting head 11 has lower requirements on the mold, and the mold is simpler. By providing the deformation groove 23 and the extrusion groove 24, the front end 20 is formed into a petal-like structure so as to generate a larger deformation amplitude to absorb vibration. The front end 20 is squeezed through the positioning hole 12, and the front end 20 and the rear end 22 are respectively located on the front and rear sides of the mounting head 11. The bolt is passed through the cavity of the middle section 21 and locked with the vehicle in conjunction with the nut to achieve connection and fixation of the mounting head 11. The bolt and nut squeeze the front end 20 to deform it, thereby achieving elastic contact.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
