Description

Technical Field

[0001] This utility model belongs to the field of rubber sleeve technology, and in particular relates to a through-hole rubber sleeve for automotive rear door wiring harness. Background Technology

[0002] Currently, when using automotive wiring harnesses to connect various electrical components in a car, it is sometimes necessary to pass the two ends of several automotive wiring harnesses through sheet metal holes on the car body and doors respectively. In order to prevent wear and tear on the automotive wiring harnesses at the sheet metal holes and to seal the gap between the automotive wiring harnesses and the sheet metal holes, rubber sheaths need to be fitted on the automotive wiring harnesses together to protect them.

[0003] Most existing through-hole rubber sleeves include corrugated flexible tubes with fixed connecting fasteners at both ends. During use, the fasteners are engaged in the sheet metal hole using the locking grooves on the fasteners. To prevent relative movement between the automotive wiring harness and the rubber sleeve, which could cause the wiring harness to detach from electrical components, tape is sometimes used to fix the wiring harness to the fasteners. However, tape fixation is not secure. Over time, the wiring harness may still detach from the fasteners and move relative to the rubber sleeve, posing a risk of the wiring harness detaching from electrical components. Therefore, existing technologies still have shortcomings and deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a through-hole rubber sleeve for automotive rear door wiring harnesses to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A through-hole rubber sleeve for automotive rear door wiring harness includes two fixing members with central through holes. Each fixing member has an annular engaging groove on its outer wall. A corrugated flexible tube is coaxially fixedly connected between the two fixing members. Both the corrugated flexible tube and the fixing members are made of rubber. An mounting ring is coaxially installed on the end of each fixing member away from the corrugated flexible tube. The inner diameter of the mounting ring is not less than the diameter of the central through hole, and the mounting ring is an internally threaded ring. A connecting tube with open ends is threaded into each mounting ring. A limiting tube located outside the fixing member is coaxially fixedly connected to the end of each connecting tube away from the corrugated flexible tube. The limiting tube is an externally threaded tube with open ends, and a locking ring is fitted and threaded onto each limiting tube. Several strip-shaped through holes are also equidistantly distributed along the circumference of the limiting tube, and these strip-shaped through holes are parallel to the limiting tube.

[0007] Furthermore, each of the fasteners has a first annular receiving groove on the outer side of the end away from the corrugated hose, and a second receiving groove adapted to the shape of the mounting ring is coaxially formed on the inner side of the fastener away from the corrugated hose. The mounting ring is located in the second receiving groove, and a plurality of bolts are provided between the mounting ring and the fastener, which are equidistantly distributed along the circumference of the mounting ring. The bolts are all parallel to the radial direction of the mounting ring, and the bolt shank ends pass through the fastener and are threadedly connected to the mounting ring. The bolt heads are located in the first receiving groove.

[0008] Furthermore, each of the second receiving grooves is coaxially installed with a limiting ring that is integral with the fixing component. The inner wall of the limiting ring is an inwardly convex arc surface. The outer wall of the mounting ring is provided with a limiting groove that matches the limiting ring. The screw end of the bolt passes through the fixing component, the limiting ring, and the mounting ring in sequence and is threadedly connected.

[0009] Furthermore, the end of each strip-shaped through hole away from the corrugated hose is flush with the end face of the limiting tube.

[0010] Furthermore, each limiting tube is fitted with two locking rings that are threaded together.

[0011] Furthermore, the outer wall of the locking ring is provided with anti-slip texture.

[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] Based on existing fasteners and corrugated hoses, this invention allows for the removal of the limiting tube by rotating the connecting tube. Since the inner diameter of the mounting ring is not less than the diameter of the central through hole, the automotive wiring harness can be easily passed through the mounting ring, fastener, and corrugated hose sequentially. After removing the limiting tube, the wiring harness can also be easily passed through the connecting tube and the limiting tube. After passing the wiring harness through the connecting tube and the limiting tube, the limiting tube can be reinstalled on the fastener by rotating the connecting tube in the opposite direction. Then, after passing the wiring harness through the strip-shaped through hole into the limiting tube, the locking ring is rotated until it is in place, allowing it to engage with the strip-shaped through hole to securely fix both ends of the wiring harness to the limiting tubes located at both ends of the corrugated hose. Compared to existing technologies, this fixing method prevents the wiring harness from detaching during long-term use, avoiding relative movement between the wiring harness and the rubber sheath, thus preventing the wiring harness from detaching from electrical components.

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, this utility model provides a through-hole rubber sleeve for automotive rear door wiring harnesses, including two fixing members 4 with central through holes 41. Each fixing member 4 has an annular engaging groove 42 on its outer wall, and a corrugated hose 3 is coaxially fixedly connected between the two fixing members 4. Both the corrugated hose 3 and the fixing members 4 are made of rubber. Specifically, both the corrugated hose 3 and the fixing members 4 are existing technologies. In use, the engaging groove 42 can be used to engage the fixing member 4 at the position of the sheet metal hole; and during the opening and closing of the car door, the corrugated hose 3 can extend and retract. An mounting ring 6 is coaxially installed on the end of each fixing member 4 away from the corrugated hose 3. 6 can be made of rigid plastic material; the inner diameter of the mounting ring 6 is not less than the diameter of the central through hole 41, and the mounting ring 6 is an internally threaded ring. The mounting ring 6 is threaded with a connecting pipe 5 with open ends. The end of the connecting pipe 5 away from the corrugated hose 3 is coaxially fixed and connected to a limiting pipe 2 located outside the fixing part 4. In use, the connecting pipe 5 can be rotated using the limiting pipe 2 to remove the limiting pipe 2; the limiting pipe 2 is an externally threaded pipe with open ends, and a locking ring 1 is fitted and threaded on the limiting pipe 2. The limiting pipe 2 is also provided with several strip-shaped through holes 21 that are equidistantly distributed along the circumference of the limiting pipe 2. The strip-shaped through holes 21 are all parallel to the limiting pipe 2.

[0021] Specifically, in use, after removing the limiting tube 2, since the inner diameter of the mounting ring 6 is not less than the diameter of the central through hole 41, it is easy to smoothly pass the automotive wiring harness through the mounting ring 6, the fixing member 4, and the corrugated hose 3 in sequence. Also, after removing the limiting tube 2, it is easy to pass the automotive wiring harness through the connecting tube 5 and the limiting tube 2 in sequence. After passing the automotive wiring harness through the connecting tube 5 and the limiting tube 2 in sequence, by rotating the connecting tube 5 in the reverse direction, the limiting tube 2 can be reinstalled on the fixing member 4. Then, after passing the automotive wiring harness through the strip-shaped through hole 21 through the limiting tube 2, by rotating the locking ring 1 until it is in place, the locking ring 1 can engage with the strip-shaped through hole 21. The two ends of the automotive wiring harness are securely fixed to the limiting tubes 2 located at both ends of the corrugated hose 3. At this time, the length of the automotive wiring harness inside the corrugated hose 3 is greater than the length of the corrugated hose 3. Compared with the existing technology, this fixing method can prevent the automotive wiring harness from falling off during long-term use, thereby avoiding relative movement between the automotive wiring harness and the rubber sheath, and thus preventing the automotive wiring harness from detaching from the electrical components. Secondly, by opening several strip-shaped through holes 21 on the limiting tube 2, during use, the locking ring 1 can cooperate with each strip-shaped through hole 21 to fix one automotive wiring harness, thereby facilitating the fixing of multiple automotive wiring harnesses to the limiting tube 2 respectively.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the end of the fixing member 4 away from the corrugated hose 3 is provided with a first annular receiving groove 43, and the end of the fixing member 4 away from the corrugated hose 3 is provided with a second receiving groove 44 coaxially adapted to the shape of the mounting ring 6. The mounting ring 6 is located in the second receiving groove 44, and a number of bolts 7 are provided between the mounting ring 6 and the fixing member 4, which are equidistantly distributed along the circumference of the mounting ring 6. The bolts 7 are all parallel to the radial direction of the mounting ring 6, and the screw end of the bolt 7 passes through the fixing member 4 and is threadedly connected to the mounting ring 6. The head of the bolt 7 is located in the first receiving groove 43. Specifically, in use, when the head of the bolt 7 is pressed against the outer wall of the fixing member 4, the mounting ring 6 can be fixedly assembled in the fixing member 4, which makes it easy to install and remove the mounting ring 6 in the fixing member 4.

[0023] Furthermore, such as Figure 1 and Figure 2As shown, each of the second receiving grooves 44 has a limiting ring 8 coaxially installed with the fixing member 4 as an integral structure. Specifically, the limiting ring 8 is made of rubber. The inner wall of the limiting ring 8 is an inwardly convex arc surface. The outer wall of the mounting ring 6 has a limiting groove 61 that matches the limiting ring 8. The screw end of the bolt 7 passes through the fixing member 4 and the limiting ring 8 and the mounting ring 6 in sequence and is threadedly connected. Specifically, in use, since the limiting ring 8 is made of rubber, when the mounting ring 6 is assembled in the fixing member 4, under the action of external force, the limiting ring can... The 8 ring deforms, and because the inner wall of the limiting ring 8 is an inwardly convex arc surface, it is easy to install the mounting ring 6 into place. By setting the limiting ring 8 and opening the limiting groove 61 on the mounting ring 6, it can cooperate with the bolt 7 to double fix the position of the mounting ring 6. At this time, when installing the bolt 7, since the fixing part 4 is also made of rubber, the mounting ring 6 can still be rotated into place within the fixing part 4. In addition, after the mounting ring 6 is installed into place, the relative position between the mounting ring 6 and the fixing part 4 can also be fixed by using sealant.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, the end of the strip-shaped through hole 21 away from the corrugated hose 3 is flush with the end face of the limiting tube 2. Specifically, when a large-sized terminal block is installed at the end of the automotive wiring harness, the locking ring 1 can be removed, and then the wire of the automotive wiring harness can be inserted into the strip-shaped through hole 21 from the end away from the corrugated hose 3, so that the automotive wiring harness can easily pass through the limiting tube 2 through the strip-shaped through hole 21.

[0025] Furthermore, such as Figures 1 to 4 As shown, each limiting tube 2 is fitted with two locking rings 1 and threadedly connected. Specifically, in use, the locking ring 1 located near the corrugated hose 3 can be used to cooperate with the strip-shaped through hole 21 to fix the end of the automotive wiring harness on the limiting tube 2. Then, the end of the automotive wiring harness can be passed through the strip-shaped through hole 21 and then through the limiting tube 2, so that the wire of the automotive wiring harness abuts against the outer wall of the locking ring 1 located near the corrugated hose 3. At this time, by rotating the other locking ring 1, after the other locking ring 1 is adjusted into place, the position of the automotive wiring harness can be doubled by the cooperation of the two locking rings 1 to improve the fixing effect. At the same time, the automotive wiring harness can also be placed back in the limiting tube 2 to facilitate the sorting of the automotive wiring harness.

[0026] Furthermore, the outer wall of the locking ring 1 is provided with anti-slip texture, which makes it easy to rotate the locking ring 1 on the limiting tube 2 during use.
