On the other hand, it can prevent conduction and leakage of electricity after water intrusion. Second, it can also prevent solid particles such as dust from entering.

[0003] The wire routing inside the existing Y-shaped waterproof connector usually needs to be bent vertically. The wire is in a bent state for a long time, and the wire will be affected by bending stress, causing metal fatigue and easy fracture. At the same time, the insulating protective layer of the wire will also have cracks, thereby reducing the insulation performance of the wire. Therefore, the applicant has made a beneficial design and found a method to solve the above problems. The technical solution to be introduced below was generated under this background. Summary of the Invention

[0031] Reference example Figures 1 to 5 , a Y-shaped waterproof connector, including a first pipe body 1 and a second pipe body 2. The second pipe body 2 is threadedly connected to the first pipe body 1. Two sides of the second pipe body 2 are provided with second interfaces 21 and are inclined. The second interfaces 21 communicate with the second pipe body 2. Therefore, a wire fixing inner core 3 is provided in the first pipe body 1. A plurality of wire inlet holes 31 are evenly distributed at both ends of the wire fixing inner core 3 with a dot as the axis. A flared portion 32 is provided at the entrance of the wire inlet hole 31. Through the inclined second interfaces 21, the bending angle required for the wire is reduced, and the wire is prevented from being in a vertically bent state for a long time, thereby prolonging the service life of the wire;

[0032] It is worth mentioning that the first pipe body 1 is provided with a first interface 11. First nut parts 4 are provided on both ends of the first pipe body 1 and the outer wall of the second pipe body 2. A first sealing ring 5 is provided between the connection of the first pipe body 1 and the second pipe body 2. Using a tool to engage with the first nut part 4 provides support for the first pipe body 1 and the second pipe body 2. Using a tool to engage with the outer wall of the second nut part 72 and rotating the tool of the second nut part 72 can reduce the force required to rotate the tightening cap 7. The first sealing ring 5 ensures the connection sealing performance between the first pipe body 1 and the second pipe body 2;

[0033] It is worth mentioning that several equally spaced air claws 6 are evenly distributed around a dot at the entrances of the first interface 11 and the second interface 21. The air claw 6 is provided with an inclined barb portion 61, and a second sealing ring 62 is arranged inside the air claw 6. The inclined barb portion 61 increases the contact area with the second sealing ring 62;

[0034] It is worth mentioning that the first interface 11 and the second interface 21 are threadedly connected with a tightening cap 7. The inner wall of the tightening cap 7 is provided with a neck portion 71 and abuts against the top of the air claw 6. The tightening cap 7 is provided with a second nut portion 72, and several anti-slip grooves 73 are arranged on the outer wall of the second nut portion 72. Pass the wire through the tightening cap 7 and the second sealing ring 62, and tighten the tightening cap 7. Affected by the inclined surface of the neck portion 71, the air claw 6 gradually moves towards the axis direction of the first interface 11 and the second interface 21, the distance between the air claws 6 gradually decreases, and the barb portion 61 squeezes the second sealing ring 62 to deform and closely adhere to the insulating layer of the wire, thus playing a role in waterproofing and dustproofing. The anti-slip grooves 73 increase the friction force for manually screwing the tightening cap 7;

[0035] It is worth mentioning that a wiring terminal 33 is arranged between the wire inlet holes 31, and the wiring terminal 33 fixes and electrically connects the wires;

[0036] It is worth mentioning that the flared portion 32 is set to be oval. When two wires need to be connected to a single wire inlet hole 31, since the diameter of the insulating layer of the wire is larger than the exposed part of the wire, the traditional wire fixing inner core 3 cannot accommodate two wires at the entrance of the wire inlet hole 31, resulting in inconvenient wiring. However, the oval flared portion 32 of this product facilitates the accommodation of two wires, enabling the two wires not to interfere with each other. Moreover, the flared portion 32 effectively protects the exposed parts of the wires.

[0037] Through the above design scheme, the product can achieve the advantages of being convenient for wire accommodation and improving the service life of the wires.
