Abstract

This application discloses a high-temperature resistant injection-molded motor wire harness, relating to the field of injection-molded wire harnesses. It includes a wire harness body with a heat dissipation assembly. The heat dissipation assembly includes a heat-conducting pipe located on one side of the wire harness body, with connecting blocks at both ends of the heat-conducting pipe. Through the cooperative arrangement of the heat-conducting pipe, connecting blocks, and protective sleeve, in use, an external air pipe is first connected to the heat-conducting pipe via the connecting assembly. Simultaneously, the protective sleeve protects the wire harness body. When the wire harness body dissipates heat during operation, the heat is absorbed by the heat-conducting pipe, and air is blown through the air pipe to expel the heat from the heat-conducting pipe, thus dissipating heat from the wire harness body. This minimizes the problem of heat generated by the wire harness itself accumulating inside the cable during operation, making it difficult to dissipate and reducing the heat dissipation effect.

Description

Technical Field

[0001] This application relates to the field of injection-molded wire harnesses, and more particularly to a high-temperature resistant injection-molded wire harness for motors. Background Technology

[0002] Injection-molded wire harnesses are products made by combining wires, connectors, or other components with plastic through injection molding. They have a stable structure and protective properties. Thermoplastic plastic is injected into a mold by an injection molding machine and cooled to form the desired shape. This process enhances the durability and waterproof performance of the wire harness. The injection-molded layer can resist the corrosion of oil, water stains, and dust, achieving a protection level of IP67 or higher, while reducing the impact of external forces on the contact quality.

[0003] The utility model patent with announcement number CN218242437U proposes a high-temperature resistant motor wire harness, including a connector, which connects to a cable. The two sides of the connector housing have multiple ventilation holes, and a clamping mechanism is fixedly connected to the tail end of the connector.

[0004] One of the high-temperature motor wiring harnesses mentioned above dissipates heat from the connectors through ventilation holes. However, during operation, the heat generated by the harness itself tends to accumulate inside the cable and is difficult to dissipate, resulting in a reduced heat dissipation effect. Utility Model Content

[0005] To address the aforementioned issues, this application provides a high-temperature resistant injection-molded wire harness for motors.

[0006] The high-temperature resistant motor injection-molded wire harness provided in this application adopts the following technical solution:

[0007] A high-temperature resistant injection-molded motor wire harness includes a wire harness body, on which a heat dissipation assembly is provided. The heat dissipation assembly includes a heat-conducting pipe located on one side of the wire harness body. Both ends of the heat-conducting pipe are provided with connecting blocks. Both ends of the heat-conducting pipe pass through the connecting blocks and form a fixed connection. A protective sleeve is fixedly connected between the two connecting blocks. The heat-conducting pipe and the wire harness body are both located inside the protective sleeve. One end of the heat-conducting pipe is provided with a connecting assembly for connecting to an external air pipe.

[0008] By adopting the above technical solution, during use, the external air pipe is first connected to the heat-conducting pipe through the connecting component, and the wire harness body is protected by the protective sleeve. When the wire harness body dissipates heat during operation, the heat is absorbed by the heat-conducting pipe, and air is blown through the air pipe to expel the heat inside the heat-conducting pipe, thus dissipating heat from the wire harness body. This minimizes the problem that the heat dissipated by the wire harness itself during operation is easily accumulated inside the cable and difficult to dissipate, which would reduce the heat dissipation effect.

[0009] Preferably, the connecting assembly includes a connecting plate fixedly connected to one end of the heat-conducting pipe. A connecting pipe communicating with the heat-conducting pipe is fixedly connected to the side wall of the connecting plate away from the heat-conducting pipe. A sliding groove is formed on one side wall of the connecting plate above the connecting pipe. A bidirectional screw is rotatably connected in the sliding groove. Two sliders threaded to the bidirectional screw are slidably arranged in the sliding groove. An arc-shaped clamping plate is fixedly connected to one end of each slider. The two arc-shaped clamping plates are respectively located on both sides of the connecting pipe.

[0010] By adopting the above technical solution, the connecting tube is inserted into the external air tube, and then the bidirectional screw is rotated to make the two sliders slide in the groove and move closer to each other, which in turn drives the two arc-shaped clamping plates to move closer to each other, so that the air tube is abutted against the connecting tube, making it convenient to connect the air tube and the connecting tube.

[0011] Preferably, a positioning groove is provided on one side wall of the connecting plate below the connecting pipe, a positioning rod is fixedly connected in the positioning groove, and two positioning blocks are sleeved on the positioning rod. The positioning blocks are respectively fixedly connected to the arc-shaped clamping plate.

[0012] By adopting the above technical solution, the positioning block can slide in the positioning groove through the positioning rod and the positioning groove, which can improve the stability of the arc-shaped clamping plate and prevent the arc-shaped clamping plate from swaying.

[0013] Preferably, elastic rubber pads are fixedly connected to the opposite sidewalls of the two arc-shaped clamping plates.

[0014] By adopting the above technical solution, the stability of the arc-shaped clamping plate can be improved by using the elastic rubber pad, while reducing the wear on the external air pipe.

[0015] Preferably, a conical rubber sealing sleeve is fixedly connected to the side wall of the connecting pipe.

[0016] By adopting the above technical solution, when the connecting tube is inserted into the external air tube, the conical rubber sealing sleeve can improve the sealing between the connecting tube and the air tube and prevent gas leakage.

[0017] Preferably, multiple sets of support blocks are fixedly connected to the side wall of the heat pipe, and each support block is fixedly connected to the inner wall of the protective sleeve.

[0018] By adopting the above technical solution, the strength of the protective sleeve can be improved by the support block, preventing the protective sleeve from being squeezed and deformed, which would damage the wire harness body.

[0019] Preferably, a dust cover is threaded to the end of the heat pipe away from the connecting pipe, and two heat dissipation holes are opened on the side wall of the dust cover, with a dust mesh fixedly connected inside the heat dissipation holes.

[0020] By adopting the above technical solution, the dust cover can be threaded onto one end of the heat pipe to prevent dust and other debris from entering the heat pipe, while also making it easy to remove the dust cover for cleaning.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the coordinated design of structures such as heat pipes, connecting blocks, and protective sleeves. During use, the external air pipe is first connected to the heat pipe via the connecting assembly, while the protective sleeve protects the wire harness body. When the wire harness body dissipates heat during operation, the heat pipe absorbs the heat, and air is blown through the air pipe to expel the heat from the heat pipe, thus dissipating heat from the wire harness body. This minimizes the problem of heat dissipation being reduced because the heat dissipated by the wire harness itself tends to accumulate inside the cable during operation and is difficult to dissipate.

[0023] 2. By inserting the connecting tube into the external air tube, and then rotating the double-ended screw, the two sliders slide in the groove and move closer to each other, which in turn moves the two arc-shaped clamping plates closer to each other, bringing the air tube against the connecting tube, making it easy to connect the air tube to the connecting tube.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a high-temperature resistant motor injection molding wire harness.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A high-temperature resistant motor injection molding wire harness includes a wire harness body 1, and a heat dissipation component is provided on the wire harness body 1. The heat dissipation component includes a heat conduction pipe 2, a connecting block 3 and a protective sleeve 4.

[0032] The heat-conducting pipe 2 is located on one side of the wire harness body 1. There are two connecting blocks 3, which are located at both ends of the heat-conducting pipe 2. The two ends of the heat-conducting pipe 2 pass through the connecting blocks 3 and form a fixed connection. The two ends of the wire harness body 1 pass through the connecting blocks 3 and are fixedly connected with plugs. The wire harness body 1 and the connecting blocks 3 are fixedly connected. The protective sleeve 4 is located between the two connecting blocks 3 and forms a fixed connection. The heat-conducting pipe 2 and the wire harness body 1 are both located inside the protective sleeve 4. One end of the heat-conducting pipe 2 is provided with a connecting component for connecting to an external air pipe.

[0033] Reference Figure 1 and Figure 3 The connecting assembly includes a connecting plate 5 fixedly connected to one end of the heat-conducting pipe 2. A connecting pipe 6 connected to the heat-conducting pipe 2 is fixedly connected to the side wall of the connecting plate 5 away from the heat-conducting pipe 2. A groove 7 is opened on one side wall of the connecting plate 5 above the connecting pipe 6. A bidirectional screw 8 is rotatably connected in the groove 7. Two sliders 9 are slidably arranged in the groove 7 and threadedly connected to the bidirectional screw 8. An arc-shaped clamping plate 10 is fixedly connected to one end of each slider 9. The two arc-shaped clamping plates 10 are located on both sides of the connecting pipe 6. By inserting the connecting pipe 6 into the external air pipe and then rotating the bidirectional screw 8, the two sliders 9 slide in the groove 7 and move closer to each other, which in turn moves the two arc-shaped clamping plates 10 closer to each other, bringing the air pipe against the connecting pipe 6, thus facilitating the connection between the air pipe and the connecting pipe 6.

[0034] Reference Figure 3 A positioning groove 11 is provided on one side wall of the connecting plate 5 below the connecting pipe 6. A positioning rod 12 is fixedly connected in the positioning groove 11. Two positioning blocks 13 are sleeved on the positioning rod 12. The positioning blocks 13 are fixedly connected to the arc-shaped clamping plate 10 respectively. By connecting the positioning rod 12 and the positioning groove 11, the positioning blocks 13 can slide in the positioning groove 11, which can improve the stability of the arc-shaped clamping plate 10 and prevent the arc-shaped clamping plate 10 from swinging.

[0035] Reference Figure 3 Elastic rubber pads 14 are fixedly connected to the side walls of the two arc-shaped clamping plates 10 on opposite sides. The elastic rubber pads 14 can improve the clamping stability of the arc-shaped clamping plates 10 and reduce the wear on the external air pipe.

[0036] Reference Figure 3A conical rubber sealing sleeve 15 is fixedly connected to the side wall of the connecting pipe 6. When the connecting pipe 6 is inserted into the external air pipe, the conical rubber sealing sleeve 15 can improve the sealing between the connecting pipe 6 and the air pipe and prevent gas leakage.

[0037] Reference Figure 2 Multiple sets of support blocks 16 are fixedly connected to the side wall of the heat pipe 2. All support blocks 16 are fixedly connected to the inner wall of the protective sleeve 4. The support blocks 16 can improve the strength of the protective sleeve 4 and prevent the protective sleeve 4 from being squeezed and deformed, which would damage the wire harness body 1.

[0038] Reference Figure 1 and Figure 4 A dust cover 17 is threaded to the end of the heat pipe 2 away from the connecting pipe 6. Two heat dissipation holes 18 are opened on the side wall of the dust cover 17. A dust filter 19 is fixedly connected inside the heat dissipation holes 18. By threading the dust cover 17 to one end of the heat pipe 2, dust and other debris can be prevented from entering the heat pipe 2. At the same time, it is convenient to remove the dust cover 17 to clean the dust filter 19.

[0039] The implementation principle of the high-temperature resistant motor injection molding wire harness in this application embodiment is as follows: In use, firstly, the connecting pipe 6 is inserted into the external air pipe, and then the bidirectional screw 8 is rotated to make the two sliders 9 slide in the slide groove 7 and move closer to each other, driving the two arc-shaped clamping plates 10 to move closer to each other, so that the air pipe abuts against the connecting pipe 6, and the air pipe is connected to the connecting pipe 6. Then, the dust cover 17 is threaded to one end of the heat conduction pipe 2 to prevent dust and other debris from entering the heat conduction pipe 2. When the wire harness body 1 dissipates heat during operation, the heat is absorbed by the heat conduction pipe 2. At the same time, air is blown into the heat conduction pipe 2 through the air pipe to discharge the heat in the heat conduction pipe 2 from the heat dissipation hole 18, thereby dissipating heat from the wire harness body 1. This avoids the problem that the heat dissipated by the wire harness itself during operation is easy to accumulate inside the cable and is difficult to dissipate, which would reduce the heat dissipation effect.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
