[0030] Reference is made below to Figure 1 describe the heat shrinkable tube 100 according to an embodiment of the present utility model

[0031] As Figure 1 shown, the heat shrinkable tube 100 according to an embodiment of the present utility model includes a heat shrinkable tube body 10, a tin ring 20, and two sets of glue rings 30.

[0032] Specifically, along the length direction of the heat shrinkable tube body 10 (such as Figure 1 the a direction shown), the heat shrinkable tube body 10 includes a first tube section 1, a connecting tube section 2, and a second tube section 3 that are connected in sequence. At least one of the first tube section 1 and the second tube section 3 has an inner diameter that gradually increases in the direction away from the connecting tube section 2. When the wire harness is inserted into the heat shrinkable tube body 10, the two sets of wire harnesses respectively enter the heat shrinkable tube body 10 through one end of the first tube section 1 away from the connecting tube section 2 and one end of the second tube section 3 away from the connecting tube section 2. And when the wire harness enters the heat shrinkable tube body 10, the inner diameter at the opening 11 of the first tube section 1 or the second tube section 3 away from the connecting tube section 2 is larger, which is convenient for the wire harness to penetrate into the first tube section 1 or the second tube section 3, making the connection of the wire harness more convenient.

[0033] As Figure 1 shown, the tin ring 20 is sleeved inside the connecting tube section 2, and the glue rings 30 are sleeved inside the connecting tube section 2. Along the length direction of the connecting tube section 2 (such as Figure 1 the a direction shown), the two sets of glue rings 30 are respectively located on opposite sides of the tin ring 20. After the two sets of wire harnesses are electrically connected, the positions of the heat shrinkable tube body 10 provided with the two sets of glue rings 30 can be baked at a high temperature respectively. The glue rings 30 melt and shrink, and can respectively fix the two sets of wire harnesses. The connecting device of the two sets of wire harnesses is arranged at the tin ring 20. The tin ring 20 in the middle of the two sets of glue rings 30 is baked at a high temperature, and the tin ring 20 melts and shrinks, which can fix the connection position of the two sets of wire harnesses. Finally, the heat shrinkable tube body 10 as a whole melts and shrinks to fit the outer wall of the wire harness, and the reliable connection of the two sets of wire harnesses can be quickly realized.

[0034] In addition, the heat shrinkable tube 100 can be set to different sizes according to the size of the wire harness. Wire harnesses of different sizes are adapted to heat shrinkable tubes 100 of different sizes, and the connection operation of the wire harness is more convenient.

[0035] The heat shrinkable tube 100 according to the embodiments of the present utility model has the inner diameter of at least one of the first tube section 1 and the second tube section 3 of the heat shrinkable tube 100 gradually increasing in the direction away from the connecting tube section 2. When the wire harness enters the heat shrinkable tube body 10, the inner diameter at the opening 11 of the first tube section 1 or the second tube section 3 away from the connecting tube section 2 is larger, facilitating the wire harness to penetrate into the first tube section 1 or the second tube section 3, making the connection of the wire harness more convenient. And after the two groups of wire harnesses are electrically connected, the positions provided with the two groups of glue rings 30 in the connecting tube section 2 can be baked at high temperature respectively. The glue rings 30 melt and shrink, and can respectively fix the two groups of wire harnesses. The connecting device of the two groups of wire harnesses is arranged at the tin ring 20. The tin ring 20 at the middle of the two groups of glue rings 30 is baked at high temperature, and the tin ring 20 melts and shrinks, which can fix the connection position of the two groups of wire harnesses. Finally, the whole heat shrinkable tube body 10 melts and shrinks to fit the outer wall of the wire harness, and the reliable connection of the two groups of wire harnesses can be quickly realized.

[0036] In some embodiments of the present utility model, as Figure 1 shown, the inner wall of the connecting tube section 2 has a first groove 21 recessed outward. The first groove 21 extends in a circumferential direction of the connecting tube section 2 as a ring shape, and at least part of the tin ring 20 is arranged in the first groove 21. It can avoid the tin ring 20 occupying the installation space of the wire harness and facilitate the wire harness to penetrate into the inside of the connecting tube section 2.

[0037] In some embodiments of the present utility model, as Figure 1 shown, the inner wall of the connecting tube section 2 has a second groove 22 recessed outward. The second groove 22 extends in a circumferential direction of the connecting tube section 2 as a ring shape, and at least part of the glue ring 30 is arranged in the second groove 22. It can avoid the glue ring 30 occupying the installation space of the wire harness and facilitate the wire harness to penetrate into the inside of the connecting tube section 2.

[0038] In some embodiments of the present utility model, as Figure 1 shown, each group of glue rings 30 includes a plurality of glue rings 30, and the plurality of glue rings 30 in the same group are arranged at intervals along the length direction of the connecting tube section 2. When baking the position provided with the glue ring 30 of the heat shrinkable tube body 10 at high temperature, it can avoid the fixing failure of the wire harness caused by the melting of a single glue ring 30. Other glue rings 30 in the same group of glue rings 30 can fix the position of the wire harness, increasing the reliability of the installation position of the wire harness.

[0039] And the plurality of glue rings 30 can fix the wire harness at multiple places, increasing the reliability of the installation position of the wire harness.

[0040] In some embodiments of the present utility model, as Figure 1As shown, along the axial direction of the heat-shrinkable tube body 10, the distance between two adjacent rubber rings 30 in the same group of rubber rings 30 is equal. This makes the layout of the rubber rings 30 more beautiful and reasonable, and the arrangement of the rubber rings 30 is more uniform. The positions where the rubber rings 30 fix the wire harness are more uniform, which can increase the reliability of the installation positions of the wire harness.

[0041] In some embodiments of the present utility model, as Figure 1 shown, along the axial direction of the heat-shrinkable tube body 10, the distance between two adjacent rubber rings 30 in one group of rubber rings 30 is equal to the distance between two adjacent rubber rings 30 in another group of rubber rings 30. This can make the fixing effects of the two ends of the position where the wire harness is connected on the wire harness relatively close, and the strengths of the two ends of the wire harness are relatively close.

[0042] In some embodiments of the present utility model, as Figure 1 shown, there are multiple tin rings 20, and the multiple tin rings 20 are arranged at intervals along the length direction of the connecting pipe section 2. When the position of the heat-shrinkable tube body 10 provided with the tin rings 20 is baked at a high temperature, it can avoid the fixing failure of the connection position of the two groups of wire harnesses caused by the melting of a single tin ring 20. Other tin rings 20 can fix the connection position of the two groups of wire harnesses, increasing the connection reliability of the connection position of the two groups of wire harnesses.

[0043] And the multiple tin rings 20 can fix the connection position of the two groups of wire harnesses at multiple places, increasing the connection reliability of the connection position of the two groups of wire harnesses.

[0044] In some embodiments of the present utility model, as Figure 1 shown, along the axial direction of the heat-shrinkable tube body 10, the distance between two adjacent tin rings 20 is equal. This makes the layout of the tin rings 20 more beautiful and reasonable, and the arrangement of the tin rings 20 is more uniform. The fixing of the connection position of the two groups of wire harnesses by the tin rings 20 is more uniform, which can increase the connection reliability of the connection position of the two groups of wire harnesses.

[0045] In some embodiments of the present utility model, as Figure 1 shown, along the axial direction of the heat-shrinkable tube body 10, the distance between the two groups of rubber rings 30 and the tin rings 20 is equal. This can make the fixing effects of the two ends of the position where the two groups of wire harnesses are connected on the wire harness relatively close, and the strengths of the two ends of the two groups of wire harnesses are relatively close.

[0046] In some embodiments of the present utility model, the rubber ring 30 is a hot-melt rubber ring 30, and it can melt and shrink relatively quickly when the rubber ring 30 is baked at a high temperature, increasing the reliability of the melting and shrinking of the rubber ring 30.

[0047] In some embodiments of the present utility model, an insulating layer is provided on the outer wall surface of the heat-shrinkable tube body 10, so that the heat-shrinkable tube 100 has a better insulating effect, increasing the electrical safety of the connection position of the two groups of wire harnesses.

[0048] In some embodiments of the present utility model, a fireproof layer is provided on the outer wall surface of the heat shrinkable tube body 10, which can enhance the fireproof effect at the connection position of the two sets of wire harnesses and improve the thermal safety at the connection position of the two sets of wire harnesses.

[0049] The wire harness connection device according to an embodiment of the present utility model includes two sets of wire harnesses and the above-mentioned heat shrinkable tube 100. The heat shrinkable tube 100 is sleeved on the electrical connection position of the two sets of wire harnesses. The two sets of wire harnesses respectively extend into the connection tube section 2 from the first tube section 1 and the second tube section 3 and are connected within the connection tube section 2.

[0050] For example, during the vehicle repair process, when connecting the wire harnesses, the heat shrinkable tube 100 can be used for connection, which can reduce the skilled repair time and enhance the user experience.

[0051] In the wire harness connection device according to an embodiment of the present utility model, by gradually increasing the inner diameter of at least one of the first tube section 1 and the second tube section 3 of the heat shrinkable tube 100 in the direction away from the connection tube section 2, when the wire harness enters the heat shrinkable tube body 10, the inner diameter at the opening 11 of the first tube section 1 or the second tube section 3 away from the connection tube section 2 is larger, facilitating the penetration of the wire harness into the first tube section 1 or the second tube section 3, making the connection of the wire harnesses more convenient. And after the two sets of wire harnesses are electrically connected, the positions provided with the two sets of rubber rings 30 within the connection tube section 2 can be baked at high temperature respectively. The rubber rings 30 melt and shrink, which can respectively fix the two sets of wire harnesses. The connection device of the two sets of wire harnesses is arranged at the tin ring 20. By baking the tin ring 20 in the middle of the two sets of rubber rings 30 at high temperature, the tin ring 20 melts and shrinks, which can fix the connection position of the two sets of wire harnesses. Finally, the heat shrinkable tube body 10 as a whole melts and shrinks to fit the outer wall of the wire harness, and the reliable connection of the two sets of wire harnesses can be quickly realized.
