Description

Technical Field

[0001] This utility model belongs to the field of rubber sheath technology, and in particular relates to a sealing rubber sheath for high-voltage wiring harnesses of new energy vehicles. Background Technology

[0002] Currently, all high-voltage wiring harnesses installed in automobiles require rubber sheaths. The ends of these sheaths are then connected to appropriate locations on the vehicle via connectors to prevent damage to the high-voltage wiring harnesses. This is especially true in new energy vehicles, where the number of electrical components increases, sometimes resulting in a large number of high-voltage wiring harnesses within a single rubber sheath. Existing rubber sheaths are typically long, cylindrical structures that cannot be divided. This makes it difficult to pass the high-voltage wiring harnesses through the sheath, especially given its length. Furthermore, to prevent multiple high-voltage wiring harnesses from tangling, as the number of harnesses increases, the length of the sheath further complicates the process. Therefore, existing technologies still have shortcomings and deficiencies. Utility Model Content

[0003] The purpose of this invention is to provide a sealing rubber sleeve for high-voltage wiring harnesses in new energy vehicles, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A sealing rubber sheath for high-voltage wiring harnesses in new energy vehicles includes a wiring harness sheath body with openings at both ends. Each end of the wiring harness sheath body is fitted with a connector coaxially aligned with the sheath body. Both ends of the connector are open. The wiring harness sheath body includes two corrugated tubes made of rubber, each with an opening at both ends. One end of each corrugated tube is fitted with the connector, and the other end of each corrugated tube is detachably fitted with a first plastic tube with openings at both ends. The end of the first plastic tube furthest from the corrugated tube is located outside the corrugated tube. A connecting tube is slidably fitted between the two first plastic tubes. The length of the connecting tube is less than the length of the first plastic tube outside the corrugated tube. An annular groove is formed on the inner wall of the connecting tube, and several through holes parallel to the radial direction of the connecting tube are formed along the circumference of the annular groove.

[0006] Furthermore, the end of the corrugated pipe away from the connector is fixedly connected to a sleeve that is integral with the corrugated pipe. The sleeve is a tubular structure with open ends, and the sleeve and the first plastic pipe are detachably fixedly connected.

[0007] Furthermore, the inner diameter of the end of the sleeve away from the corrugated pipe is larger than the inner diameter of the other end of the sleeve, and a matching annular disc is coaxially installed inside the sleeve. The end of the annular disc away from the corrugated pipe is coaxially fixedly connected to a second plastic tube with openings at both ends. The end of the second plastic tube away from the annular disc is located outside the sleeve, and the second plastic tube has an external thread. The first plastic tube has an internal thread and is threadedly connected to the second plastic tube.

[0008] Furthermore, a fixing plate is coaxially fixedly mounted on the end of the connector away from the bellows. The fixing plate has several mounting through holes that are equidistantly distributed along the circumference of the fixing plate, and the center line of each mounting through hole is parallel to the axial line of the fixing plate.

[0009] Furthermore, each of the fixed discs has a receiving groove coaxially formed on the side away from the bellows, and a sealing ring is coaxially embedded in each receiving groove.

[0010] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0011] The wire harness sheath body of this utility model includes two corrugated tubes, which are of a split structure. In use, after separating the two corrugated tubes, the wire harness sheath body is divided into two sections, which facilitates the sequential passing of high-voltage wire harnesses through the two corrugated tubes until all high-voltage wire harnesses have passed through the two corrugated tubes. Then, the two corrugated tubes can be connected by a connecting tube, which facilitates the passing of high-voltage wire harnesses through the rubber sheath. In addition, when the number of high-voltage wire harnesses inside the rubber sheath increases, the split structure of the wire harness sheath body also facilitates the sequential passing of multiple high-voltage wire harnesses through the rubber sheath for easy use. Furthermore, since the corrugated tubes and the first plastic tube are detachably connected, it is convenient to detach and install the first plastic tube on the corrugated tubes for assembly.

[0018] 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.

[0019] like Figures 1 to 5 As shown, this utility model provides a sealing rubber sheath for high-voltage wiring harnesses in new energy vehicles, including a wiring harness sheath body 3 with openings at both ends. Each end of the wiring harness sheath body 3 is equipped with a connector 4 coaxially aligned with the wiring harness sheath body 3. Both ends of the connector 4 are open. Specifically, the connector 4 is existing technology. In use, the connector 4 can be used to install both ends of the wiring harness sheath body 3 at appropriate positions on the vehicle. The wiring harness sheath body 3 includes two corrugated tubes 5 made of rubber material. Both ends of the corrugated tubes 5 are open, and one end of each corrugated tube 5 is equipped with the connector 4. The other end of each corrugated tube 5 is coaxially and detachably mounted with openings at both ends. The first plastic tube 1 has one end away from the corrugated pipe 5 located outside the corrugated pipe 5, and a connecting tube 10 is slidably sleeved between the two first plastic tubes 1. The length of the connecting tube 10 is less than the length of the first plastic tube 1 outside the corrugated pipe 5. Specifically, in use, the connecting tube 10 can be slid onto one of the first plastic tubes 1 before the high-voltage wire harness is threaded. An annular groove 11 is provided on the inner wall of the connecting tube 10, and the center line of the annular groove 11 is on the same straight line as the axial line of the connecting tube 10. Several through holes 12 are provided in the annular groove 11 along the circumference of the annular groove 11 and are arranged radially parallel to the connecting tube 10.

[0020] Specifically, the wire harness sheath body 3 of this utility model includes two corrugated tubes 5, which are of a split structure. In use, after separating the two corrugated tubes 5, since the wire harness sheath body 3 is in two sections, it is convenient to pass the high-voltage wire harness through the two corrugated tubes 5 one by one until all the high-voltage wire harnesses have passed through the two corrugated tubes 5. Then, the two corrugated tubes 5 can be connected by the connecting tube 10, which makes it convenient to pass the high-voltage wire harness through the rubber sheath. In addition, when the number of high-voltage wire harnesses in the rubber sheath increases, the split structure of the wire harness sheath body 3 also makes it convenient to pass multiple high-voltage wire harnesses through the rubber sheath one by one for use. Secondly, since the corrugated tube 5 and the first plastic tube 1 are detachably connected, it is convenient to detach and install the first plastic tube 1 on the corrugated tube 5 for assembly.

[0021] The specific method for connecting the two corrugated pipes 5 through the connecting pipe 10 is as follows: When connecting the two corrugated pipes 5, firstly align the ends of the two first plastic pipes 1 away from the corrugated pipe 5, and then slide the connecting pipe 10 until both ends of the connecting pipe 10 are respectively on the two first plastic pipes 1. Then, inject glue into the annular groove 11 through the through hole 12. The glue is a strong glue in the prior art. After the glue dries, fix the relative position between the connecting pipe 10 and the first plastic pipe 1 to connect the two corrugated pipes 5.

[0022] Furthermore, such as Figures 1 to 5 As shown, the end of the corrugated pipe 5 away from the connector 4 is fixedly connected to a sleeve 6 which is an integral structure with the corrugated pipe 5. That is, the sleeve 6 is made of rubber material and can be deformed under external force. The sleeve 6 is a tubular structure with open ends, and the sleeve 6 is detachably fixedly connected to the first plastic pipe 1, which makes it easy to install and remove the first plastic pipe 1 from the corrugated pipe 5.

[0023] The specific arrangement of the detachable fixed connection between the sleeve 6 and the first plastic tube 1 is as follows: Figures 1 to 5 As shown, the inner diameter of the end of the sleeve 6 away from the corrugated pipe 5 is larger than the inner diameter of the other end of the sleeve 6, forming a receiving space in the sleeve 6; and a matching annular disc 7 is coaxially installed inside the sleeve 6. The end of the annular disc 7 away from the corrugated pipe 5 is coaxially fixedly connected to a second plastic tube 2 with openings at both ends. The end of the second plastic tube 2 away from the annular disc 7 is located outside the sleeve 6, and the second plastic tube 2 has an external thread. The first plastic tube 1 has an internal thread and is threadedly connected to the second plastic tube 2. Specifically, the annular disc 7 and the second plastic tube 1 are connected... The tube 2 is a one-piece structure, made entirely of plastic. During installation, the sleeve 6 can deform, allowing the annular disc 7 to be fully inserted into the sleeve 6, and the end of the second plastic tube 2 away from the annular disc 7 to be outside the sleeve 6. Then, by rotating the first plastic tube 1 on the second plastic tube 2 until the first plastic tube 1 and the annular disc 7 are pressed against the sleeve 6, the second plastic tube 2 can be fixed on the sleeve 6, thus connecting the sleeve 6 and the first plastic tube 1. This facilitates the installation and removal of the first plastic tube 1 on the corrugated pipe 5.

[0024] Furthermore, such as Figure 1As shown, a fixing plate 8 is coaxially fixedly mounted on the end of the connector 4 away from the bellows 5. The fixing plate 8 has several mounting through holes 81 evenly distributed along the circumference of the fixing plate 8. The center line of the mounting through holes 81 is parallel to the axial line of the fixing plate 8. Specifically, during installation, a threaded hole corresponding to the position of the mounting through hole 81 can be opened at a suitable position on the car. Then, the fixing plate 8 is pressed against the car and the mounting through hole 81 is aligned with the threaded hole. At this time, a bolt can be passed through the mounting through hole 81 and then the bolt is threaded to the car through the threaded hole until the head of the bolt is pressed against the fixing plate 8. Then the fixing plate 8 can be installed on the car so that both ends of the wire harness sheath body 3 can be installed at suitable positions on the car.

[0025] Furthermore, such as Figure 1 As shown, the fixed plate 8 has a receiving groove on the side away from the bellows 5, and a sealing ring 9 is embedded in the receiving groove on the same axis. The sealing ring 9 is a ring structure made of silicone material. In use, after the fixed plate 8 is installed in a suitable position on the car, the sealing ring 9 can seal the connection between the fixed plate 8 and the car. In addition, when the high-voltage wire harness needs to be installed through a hole, a rubber protective ring or other protective parts can be installed on the same axis at the hole position to prevent the high-voltage wire harness from being worn at the hole position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
