[0019] Example 1 A preferred embodiment of the safe and waterproof wire harness provided by this utility model is as follows: Figures 1 to 5 As shown: A safe and waterproof wire harness includes: a waterproof tube 1, a wire harness body 6 installed inside the waterproof tube 1, a clamping component 2 fixed at each end of the wire harness body 6, a first connecting port 7 and a second connecting port 12 fixed at each end of the wire harness body 6, a first waterproof sleeve 3 and a second waterproof sleeve 5 respectively rotatably mounted at one end of the two clamping components 2 via a rotating seat 4, the outer side of the first waterproof sleeve 3 is provided with an external thread 9, the inner wall of the second waterproof sleeve 5 is provided with an internal thread groove 11, a limiting component 8 is installed inside the first waterproof sleeve 3, and a plurality of limiting holes 10 are equally spaced inside the second waterproof sleeve 5, the limiting holes 10 and the limiting components 8 are fitted together.

[0020] The limiting component 8 includes a mounting groove 801 welded to the inner wall of the first waterproof sleeve 3, and a spring-supported slide rod 805 is welded inside the mounting groove 801.

[0021] A sliding plate 804 is provided on the outer side of the spring support slide rod 805, and a limit plug 803 and a pressing rod 802 are welded to the top of the sliding plate 804.

[0022] The top ends of the limiting rod 803 and the pressing rod 802 slide out of the interior of the first waterproof sleeve 3, and the height of the pressing rod 802 is greater than that of the limiting rod 803.

[0023] The limiting hole 10 penetrates the interior of the second waterproof sleeve 5, and the limiting hole 10 is installed with the limiting rod 803 for limiting.

[0024] In this invention, when connecting wire harnesses, after connecting the first connection port 7 at one end of the wire harness body 6 to the second connection port 12 at the other end, since the two ends of the wire harness body 6 are respectively rotatably mounted with a first waterproof sleeve 3 and a second waterproof sleeve 5 via a rotating seat 4, and the outer side of the first waterproof sleeve 3 is provided with an external thread 9, and the inner wall of the second waterproof sleeve 5 is provided with an internal thread groove 11, the first waterproof sleeve 3 can be inserted into the interior of the second waterproof sleeve 5. Then, by rotating, the external thread 9 and the internal thread groove 11 can be threaded together, thereby connecting the first waterproof sleeve 3 and the second waterproof sleeve 5. This protects the first connection port 7 and the second connection port 12 between the first waterproof sleeve 3 and the second waterproof sleeve 5. To prevent the first waterproof sleeve 3 and the second waterproof sleeve 5 from loosening during use, as the first waterproof sleeve 3 penetrates deeper into the interior of the second waterproof sleeve 5, the first waterproof sleeve 3... The limiting rod 803 extending from the outer side of the water jacket 3 is also inserted into the interior of the second waterproof jacket 5. At this time, by pressing the pressing rod 802, the sliding plate 804 can be controlled to slide downward along the installation direction of the spring support slide rod 805, thereby driving the limiting rod 803 to be housed inside the installation groove 801. Then, by rotating the first waterproof jacket 3, the top of the limiting rod 803 is moved to the position below the limiting hole 10. At this time, by releasing the pressing rod 802, the rebound force generated by the compressed spring on the outer side of the spring support slide rod 805 can push the limiting rod 803 out of the inner wall of the first waterproof jacket 3 and insert it into the interior of the limiting hole 10, thereby limiting and fixing the installation position of the first waterproof jacket 3 and the second waterproof jacket 5, preventing the first waterproof jacket 3 and the second waterproof jacket 5 from becoming loose after being connected by threads, avoiding water ingress, and improving the safety of the wiring harness.

[0025] The clamping assembly 2 includes a sleeve 201 fixed to the outside of the wire harness body 6, and a clamping groove 206 is provided between the sleeve 201 and the wire harness body 6.

[0026] The first clamping plate 203 and the second clamping plate 204 are installed inside the sleeve 201 via a rotating shaft. A threaded rod 202 is threadedly connected to one side of the first clamping plate 203, and a threaded hole 205 is opened on one side of the second clamping plate 204.

[0027] Anti-slip pads are respectively adhered to the inner sides of the first clamping plate 203 and the second clamping plate 204, and the threaded rod 202 is connected to the threaded hole 205 by thread engagement.

[0028] In this utility model, a waterproof tube 1 is sleeved on the outside of the wire harness body 6. The waterproof tube 1 can provide waterproof protection for the entire outside of the wire harness body 6. To prevent the two ends of the waterproof tube 1 from detaching from the two ends of the wire harness body 6, during installation, the two ends of the waterproof tube 1 can be inserted into the two clamping grooves 206 respectively. Then, by rotating the first clamping plate 203 and the second clamping plate 204, one end of the waterproof tube 1 can be pressed into the clamping groove 206. Then, by rotating the threaded rod 202, one end of the threaded rod 202 is inserted into the threaded hole 205, thereby fixing the first clamping plate 203 and the second clamping plate 204. At the same time, one end of the waterproof tube 1 is tightly pressed into the clamping groove 206. The anti-slip pads installed on the inner side of the first clamping plate 203 and the second clamping plate 204 can prevent the two ends of the waterproof tube 1 from falling off, thereby improving the waterproof effect of the waterproof tube 1 on the outside of the wire harness body 6.

[0029] Working principle: The first connection port 7 at both ends of the wire harness body 6 is precisely aligned with the second connection port 12 to ensure circuit continuity. The first waterproof sleeve 3 and the second waterproof sleeve 5 are rotated via the rotating base 4, inserting the first waterproof sleeve 3 into the second waterproof sleeve 5, causing the external thread 9 to engage with the internal thread groove 11 and tighten, initially protecting the connection port. Pressing the pressing rod 802 causes the sliding plate 804 to slide downwards along the spring-supported sliding rod 805, and the limiting insertion rod 803 is retracted into the mounting groove 801. The first waterproof sleeve 3 is then rotated to… Align the limiting rod 803 with the target limiting hole 10, release the pressing rod 802, the spring rebounds and pushes the sliding plate 804 upward, the limiting rod 803 is inserted into the limiting hole 10, and the waterproof sleeve is fixed. Insert both ends of the waterproof tube 1 into the clamping grooves 206 of the two clamping components 2 respectively, rotate the first clamping plate 203 and the second clamping plate 204 to clamp the waterproof tube 1, rotate the threaded rod 202 to screw it into the threaded hole 205, and enhance the friction through the anti-slip pad to fix the waterproof tube 1 to prevent it from falling off, thus achieving full-section waterproof protection.
