Description

TECHNICAL FIELD

[0001] The utility model relates to harness heat shrink technical field more specifically, it relates to a kind of harness heat shrink device with overheating protection. BACKGROUND

[0002] Harness with thermal protector can be used to carry out overheating protection, and the harness mainly includes wire and thermal fuse at one end of the wire, and the connecting part of the thermal fuse and the wire coating needs to be wrapped with heat shrink sleeve, which improves the connection strength on one hand and avoids electric leakage on the other hand. The heat shrink sleeve needs to be heated by a heat shrink device, and shrinks under heat, thereby fixing the wire and the thermal fuse to each other.

[0003] When the harness is heat shrunk, the heat shrink sleeve on the harness shrinks under heat, and the thermal fuse at the end of the harness is affected by heat, which may gradually accumulate heat to make the thermal fuse reach the melting temperature and be burned out, affecting the quality of the harness. Although some harness heat shrink devices have separated the thermal fuse from the harness to reduce the influence of heat on the thermal fuse during heat shrinkage. However, in the actual heat shrink process, heat will continue to be transferred to the thermal fuse through the partition plate, causing the heated part of the thermal fuse to melt. Although it does not directly cause the thermal fuse to melt under heat, it still affects the fuse, thereby affecting the quality of the harness in the subsequent use process. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a harness heat shrink device with overheating protection that separates the thermal fuse from the harness during heat shrinkage and uses air cooling to cool the fuse, thereby avoiding the influence of the heated part of the thermal fuse on the quality of subsequent use.

[0006] A harness heat shrink device with overheating protection includes a heat shrink assembly, a protection assembly installed inside the heat shrink assembly, and an air cooling assembly installed on the top of the heat shrink assembly. The heat shrink assembly includes a heat shrink cabinet, a heating plate installed inside the heat shrink cabinet, and a heating pipe installed inside the heating plate. The protection assembly includes a heat insulation plate installed on the top of the heating plate and a limiting plate installed on the top of the heat insulation plate.

[0007] The utility model is further provided as follows: the limiting plate is provided with a plurality of limiting plates along the heat insulation plate, and every two adjacent limiting plates are inclined to each other.

[0008] The utility model is further provided as follows: a limiting groove for placing the harness is formed between every two adjacent limiting plates.

[0009] By adopting the above technical solution, the wire harness that needs to be heat-shrink can be placed inside the limiting groove. On the one hand, the limiting plate can be used to evenly transfer heat to the circumference of the wire harness, ensuring that the heat-shrink sleeve on the wire harness shrinks evenly; on the other hand, the limiting plate can also be used to separate the wire harness from the terminal.

[0010] The present invention is further configured such that: multiple heating tubes are installed inside the heating plate, and the heating tubes are located at the bottom of the heat insulation plate.

[0011] The present invention is further configured such that a heating cavity is formed inside the heating plate and sealed between it and the heat insulation plate.

[0012] The present invention is further configured such that: the air-cooling component includes an air-cooling cabinet installed on the top of the heat shrink cabinet, a fan is installed on one side of the top of the air-cooling cabinet, and a motor is installed on the other side of the top of the air-cooling cabinet.

[0013] The present invention is further configured such that: an air-cooling cavity is formed inside the air-cooled cabinet, and the bottom of the fan is connected to the air-cooling cavity.

[0014] The present invention is further configured such that: the output end of the motor passes through the air-cooled cabinet downwards, and a fan blade is connected to the bottom of the motor.

[0015] The present invention is further configured such that: the fan blade is disposed inside the air-cooling cavity, and the fan blade is located on top of the protective assembly.

[0016] The beneficial effects of this utility model are:

Furthermore, during the heat shrinking process, the airflow generated by the air-cooling component cools the fuse, preventing the heated part of the thermal fuse from melting during the heat shrinking process and affecting the quality in subsequent use.

Further, the heating pipe 12 can be arranged in multiple layers in the vertical direction inside the heating plate 13, thereby increasing the heat generated by the heating pipe 12. When the wire harness is heat shrunk, the heat generated by the heating pipe 12 can be transmitted to the wire harness, so that the heat shrink sleeve on the wire harness is shrunk.

[0030] Please refer to Figures 1-5The protection assembly 2 comprises a heat insulation plate 21 installed on the top of the heating plate 13 and a limiting plate 22 installed on the top of the heat insulation plate 21. The heat insulation plate 21 is shaped to match the shape of the heating plate 13, and the heating plate 13 is internally formed with a sealed heating cavity 14 between the heat insulation plate 21, and the heat generated by the plurality of heating pipes 12 inside the heating plate 13 is gathered in the heating cavity 14, facilitating heat transfer through the heat insulation plate 21. The sealed heating cavity 14 can also avoid heat volatilization and improve heat shrinkage quality. The limiting plate 22 is provided with a plurality of limiting slots 23 between every two adjacent limiting plates 22, and the limiting slots 23 are shaped to match the shape of the wire harness. When the wire harness is placed in the limiting slot 23, the thermal fuse at the end of the wire harness is located outside the limiting slot 23 near the air cooling assembly 3, which can uniformly transfer heat to the wire harness in the circumferential direction of the limiting plate 22 to ensure uniform heat shrinkage of the heat shrink sleeve on the wire harness, and also separates the wire harness from the terminal.

[0031] Please refer to Figures 1-3 The air cooling assembly 3 comprises an air cooling cabinet 31 installed on the top of the heat shrinkage cabinet 11, a fan 32 installed on one side of the top of the air cooling cabinet 31, and a motor 33 installed on the other side of the top of the air cooling cabinet 31. The air cooling cabinet 31 is internally formed with an air cooling cavity 35 located on the top of the heat insulation plate 21, and a partition is provided inside the air cooling cabinet 31 to separate the air cooling cavity 35 from the limiting plate 22 on the top of the heat insulation plate 21. The bottom of the fan 32 is in communication with the air cooling cavity 35.

During the heat shrink process, the airflow generated by the operation of the fan flows into the air cooling cavity 35, and the motor 33 drives the fan blade 34 to rotate to diffuse the airflow generated by the fan 32 and cool the thermal fuse. The limiting plate 22 not only separates the wire harness and the thermal fuse, but also uniformly transmits heat to the wire harness by the limiting plate 22, further cools the fuse by the airflow generated by the air cooling assembly 3 during the heat shrink process, avoids the heat shrink process of the thermal fuse, and affects the quality in the subsequent use process.
