[0002] As the integration of electronic functions of automobiles continues to increase, the number of wiring harnesses also increases, which leads to low efficiency in automobile production and inconvenience in installation. Since automobiles are assembled from multiple independent modules. Each independent module has its own control wiring harness. If these wiring harnesses are not rationally regulated, on the one hand, the wiring harnesses appear messy and not beautiful; on the other hand, the cross-confusion of the wiring harnesses will reduce the assembly efficiency of the entire vehicle, and at the same time, it will also affect the stability of the car's operation to a certain extent. In addition, as far as the car is concerned, the most frequent place for automobile activities is the door. However, since the door integrates functions such as electronic locks, windows, and speakers, there are some wiring harnesses. If the assembly is performed by punching holes in the door, on the one hand, the processing difficulty increases, and on the other hand, the wiring harness still has problems such as exposure. Therefore, the wiring harness on the door is protected by a sealed wire sheath. However, the wiring harness is difficult to fix in the existing sealed wire sheath, and the wiring harness moves back and forth or moves left and right, which needs to be improved.

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Reference Figure 1-Figure 4A sealed wire-passing sleeve for a car door harness comprises a connecting tube 1, a door-end sealing rib 2 and a body-end sealing rib 3. The two ends of the connecting tube 1 are respectively connected and fixed to the door-end sealing rib 2 and the body-end sealing rib 3. In order to ensure a high connection strength between the connecting tube 1 and the door-end sealing rib 2, a second reinforcing rib 11 is fixedly arranged between the connecting tube 1 and the door-end sealing rib 2. A through hole 12 is formed through the length direction of the connecting tube 1, and a fixing bracket 5 is fixedly arranged at the body-end sealing rib 3, and a forming bracket 4 is fixedly arranged at the door-end sealing rib 2. A fixing groove is formed at the body sheet metal surface, and the body-end sealing rib 3 is fixedly installed and connected to the fixing groove of the body sheet metal surface through the fixing bracket 5, and the door-end sealing rib 2 is fixedly installed and connected to the door sheet metal surface through the forming bracket 4. The forming bracket 4 includes a straight section 46 and an arc-shaped bay stream guide section 41, a through groove 461 is formed in the straight section 46, and an arc-shaped bay stream guide groove 411 is formed in the arc-shaped bay stream guide section 41. The end of the straight section 46 of the forming bracket 4 is fixedly mounted on the door end sealing rib 2, so that the two ends of the through groove 461 are respectively connected to the through hole 12 and the arc-shaped bay stream guide groove 411. The wiring harness enters from the through hole 12 of the connecting tube 1 near the vehicle body end sealing rib 3, and passes through the through groove 461 and the arc-shaped bay stream guide groove 411 in sequence after passing through the connecting tube 1, so that the wiring harness is fixed along the direction of the arc-shaped bay stream guide groove 411.

[0028] The connecting pipe 1, the door-end sealing rib 2 and the body-end sealing rib 3 are all made of EPDM rubber material, which is a high-tech environmentally friendly material. The connecting pipe 1, the door-end sealing rib 2 and the body-end sealing rib 3 made of EPDM rubber material have good ozone resistance, heat resistance and aging resistance. In addition, the connecting pipe 1 made of EPDM rubber material can better fix the direction of the wiring harness, and the door-end sealing rib 2 and the body-end sealing rib 3 made of EPDM rubber material can support the rubber sealing lip, so that the sealing wire sheath lip is better fitted with the sheet metal surface, achieving a tighter sealing effect. The forming bracket 4 and the fixing bracket 5 are made of PA plastic material. The forming bracket 4 and the fixing bracket 5 made of PA plastic material have high structural strength and good impact resistance.

[0029] Reference Figure 4 and Figure 5In order to facilitate the fixing of the wire harness along the arc-shaped bay stream guide groove 411 of the forming bracket 4, an extension platform 42 is provided at the end of the arc-shaped bay stream guide section 41, and a first boss 43 is provided on the side of the extension platform 42 facing away from the arc-shaped bay stream guide groove 411. After the wire harness passes through the through hole 12 and the through groove 461 along the arc-shaped bay stream guide groove 411, the wire harness is tied and fixed to the extension platform 42 by a cable tie, and the first boss 43 limits the cable tie to prevent the cable tie from falling off the extension platform 42. The cable tie is used to tie and fix the wire harness to the extension platform 42, thereby preventing the wire harness from moving back and forth or left and right in the connecting tube 1 and the forming bracket 4.

[0030] When the wire harness passing through the through hole 12 of the connecting tube 1 is a thick wire harness, in order to facilitate the fixation between the thick wire harness and the forming bracket 4, the cross section of the arc-shaped bay stream guide section 41 is set to be semicircular, and a second boss 44 is set on the periphery of the end of the arc-shaped bay stream guide section 41. The second boss 44 is located on both sides of the extension platform 42 and is perpendicular to the outer surface of the forming bracket 4. After the thick wire harness passes through the through hole 12 of the connecting tube 1, it fits with the surface of the forming bracket 4. The cable tie is wound around the periphery of the forming bracket 4 to tie and fix the thick wire harness to the forming bracket 4, thereby preventing the wire harness from moving back and forth or left and right in the connecting tube 1 and the forming bracket 4. The setting of the second boss 44 also plays a limiting role for the cable tie. In addition, the connecting tube 1 adopts a spiral tube structure design, so that the connecting tube 1 can better shrink, stretch and smoothly transition the wire harness in the connecting tube 1 while protecting the wire harness.

[0031] When the sealed wire-passing sheath faces different installation environments, in order to enable the molded bracket 4 to meet the installation of the sealed wire-passing sheath for wire harnesses with different directions, the molded bracket 4 and the door end sealing rib 2 are detachably installed. Therefore, a mounting tube 21 is provided on the side of the door end sealing rib 2 facing away from the connecting tube 1, and mounting grooves 211 are provided on both sides of the mounting tube 21. Correspondingly, mounting protrusions 45 are provided on both sides of the straight section 46 of the molded bracket 4. When installing the molded bracket 4 and the mounting tube 21, the mounting protrusions 45 on both sides of the straight section 46 of the molded bracket 4 are embedded in the mounting grooves 211 on both sides of the mounting tube 21. The mounting protrusions 45 on both sides of the straight section 46 of the molded bracket 4 are embedded in the mounting grooves 211 on both sides of the mounting tube 21, which not only ensures firm installation and fixation, but also has the advantage of easy disassembly. In addition, in order to ensure a higher connection structural strength between the mounting tube 21 and the door end sealing rib 2 , a plurality of first reinforcing ribs 22 are fixedly arranged between the mounting tube 21 and the door end sealing rib 2 , and the plurality of first reinforcing ribs 22 are evenly distributed along the circumference of the mounting tube 21 .

[0032] Reference Figure 6 and Figure 7In order to achieve a good installation and fixing effect between the fixing bracket 5 provided at the sealing rib 3 at the end of the vehicle body and the body sheet metal surface, the fixing bracket 5 is set as a rectangular hanging push-fit integrated plastic bracket, and an end buckle 51 and an elastic buckle 52 are respectively provided at both ends of the fixing bracket 5, wherein the upper end of the end buckle 51 is inclined to the outside of the fixing bracket 5, and a clamping groove 511 is formed on the outside of the end buckle 51. When installing and fixing the fixing bracket 5 to the body sheet metal surface, the clamping groove 511 on the outside of the end buckle 51 is clamped with the end wall of the fixing groove at the body sheet metal surface, and then the elastic buckle 52 on the fixing bracket 5 is clamped and fixed with the other side end wall of the fixing groove at the body sheet metal surface, thereby completing the fixing and installation between the fixing bracket 5 and the body sheet metal surface.

[0033] The specific implementation principle of the embodiment of the present application is as follows: when using the sealed wire-passing sheath, the wire harness is passed through the through hole 12 at the sealing rib 3 at the end of the connecting tube 1 near the vehicle body, and then passed through the through hole 12 at the sealing rib 2 at the end of the connecting tube 1 near the vehicle door. The wire harness is kept along the arc-shaped Gulfstream guide groove 411 of the forming bracket 4, so that the wire harness fits the surface of the extension platform 42, and the wire harness and the extension platform 42 are tied and fixed with a cable tie. The first boss 43 provided on the outer side of the extension platform 42 limits the cable tie, thereby preventing the cable tie from slipping off the extension platform 42. When the wire harness passed through the through hole 12 is a thick wire harness, the thick wire harness is tied and fixed with the forming bracket 4 with a cable tie, and the second boss 44 on the outer side of the forming bracket 4 limits the cable tie, thereby preventing the cable tie from slipping off the forming bracket 4. The wire harness is tied and fixed to the extension platform 42 or the forming bracket 4 by a cable tie, so as to prevent the wire harness from moving back and forth or left and right in the connecting tube 1 and the forming bracket 4. The connecting tube 1 with a spiral tube structure design can protect the wire harness while enabling the wire harness to shrink, stretch and transition smoothly in the connecting tube 1.

[0034] Finally, the fixing bracket 5 at the sealing rib 3 at the end of the vehicle body is fixed to the sheet metal surface at the end of the vehicle body, and the slot 511 on one side of the end buckle 51 is clamped with one of the inner end walls in the mounting slot 211 at the end of the vehicle body sheet metal surface, and then the elastic buckle 52 is clamped and fixed with the other inner end wall in the mounting slot 211 at the end of the vehicle body sheet metal surface. The end buckle 51 and the elastic buckle 52 on the fixing bracket 5 are clamped and fixed with the mounting slot 211 at the end of the vehicle body sheet metal surface, respectively, so that the fixing is not only firm but also easy to disassemble.

[0035] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
