[0019] In one embodiment of this utility model, such as Figures 1-2As shown, a waterproof connector 10 for automotive horn wires is provided, comprising a terminal body. The terminal body includes a connector 10 and a female connector 20. One end of the connector 10 is connected to one end of the female connector 20. The connector 10 is used to fix and connect the wire, and the female connector 20 is used to insert the power supply wire. The feature is that the female connector 20 has a square opening 21 extending through it. A waterproof spring 30 is provided in the square opening 21 away from the connector 10. One end of the waterproof spring 30 is connected to one side of the square opening 21, and the other end of the waterproof spring 30 extends into the square opening 21 and abuts against the opposite side of the square opening 21. Both sides of the waterproof spring 30 slide against the female connector 20, and the waterproof spring 30 is used to close one end of the square opening 21. In this embodiment, the circuit board is disposed in the square opening 21 of the female plug 20. The wire passes through the connecting end 10 and connects to the circuit board inside the female plug 20. The stripped end of the wire extends into the female plug 20, and the end of the wire wrapped with insulating material is disposed on the connecting end 10, blocking the opening of the square opening 21 near the connecting end 10. The connecting end 10 fixes the end of the wire wrapped with insulating material. The other end of the square opening 21 is provided with a waterproof spring 30, which seals both ends of the square opening 21 of the female plug 20 to prevent moisture from entering and corroding the circuit board or wire inside the female plug 20. When the female plug 20 needs to be connected to the male plug, the male plug directly inserts into the female plug 20, and the male plug presses the waterproof spring 30 to open the waterproof spring 30 and connect with the circuit board inside the female plug 20. At this time, the male plug blocks one end of the square opening 21 of the female plug 20, and the waterproof spring 30 abuts against the male plug to prevent the male plug from falling off.
[0020] Furthermore, a buffer portion 31 is provided at the end of the waterproof spring 30 that abuts against the square opening 21, extending towards the connection end 10 with the square opening 21. In this embodiment, the buffer portion 31 is used to enhance the rebound force of the waterproof spring, preventing the waterproof spring from bending at too large an angle due to the insertion of the male end, which would cause the waterproof spring 30 to lose its rebound force directly. At the same time, it strengthens the pressing force of the waterproof spring on the male end, preventing the male end from falling off the female end 20.
[0021] Furthermore, a welding portion 22 extends outward from one end of the outer surface of the female connector 20. In this embodiment, the welding portion 22 is used to facilitate the fixing and welding of the waterproof connector 10 for car horn wires provided by this utility model to the place where fixation is required.
[0022] Furthermore, the connecting end 10 includes a first connecting portion 11 and a second connecting portion 12. One end of the first connecting portion 11 is connected to the female plug end 20, and the other end is connected to the second connecting portion 12. The first connecting portion 11 is used to guide the wire into the female plug end 20, and the second connecting portion 12 is used to fix the wire. In this embodiment, the first connecting portion 11 is used to guide the wire into the female plug end 20 to facilitate wire installation, and the second connecting portion 12 is used to fix the wire to prevent the wire from falling out of the connecting end 10.
[0023] Furthermore, the first connecting part 11 is a first U-shaped plate 13 with its opening facing upwards. The first U-shaped plate 13 is also provided with several friction grooves 14. The first U-shaped plate 13 is used to guide the wire into the female plug end 20. In this embodiment, the friction grooves 14 are used to increase the friction between the wire and the first U-shaped plate 13, preventing the wire from sliding on the first U-shaped plate 13, thereby affecting the connection between the stripped end of the wire and the circuit board inside the female plug end 20 or preventing the plastic-wrapped end of the wire from blocking the square opening 21.
[0024] Furthermore, the second connecting portion 12 is a second U-shaped plate 15 with its opening facing upwards. The width of the second U-shaped plate 15 is greater than that of the first U-shaped plate 13, and bending plates 16 extend upwards from both sides of the second U-shaped plate. In this embodiment, when the wire is placed on the second U-shaped plate 15, the two bending plates 16 bend inwards towards the second U-shaped plate 15 to secure the wire on the second U-shaped plate 15 and prevent the wire from sliding on the connecting end 10.
[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
