[0021] Example: See Figures 1 to 6 This embodiment provides a grounding protection connector, which includes a female connector body 1 and a grounding device 2.
[0022] The female connector body 1 includes a live wire terminal 11, a neutral wire terminal 12, a ground terminal 13, an inner shell 14, and an outer shell 15. The outer shell 15 covers the inner shell 14. One side of the inner shell 14 is provided with a plug-in portion 141 extending out of the outer shell 15. There are two mounting holes 142 arranged side by side on the plug-in portion 141. The live wire terminal 11 and the neutral wire terminal 12 are respectively arranged in the two mounting holes 142. One surface of the inner shell 14 is exposed to form a slide 143. The two sides of the slide 143 are symmetrically provided with sliding hook grooves 144.
[0023] The grounding device 2 is mounted on the slide table 143 and connected to the grounding terminal 13. The grounding device 2 can protrude or retract from the slide table 143, resulting in good grounding performance. Specifically, the grounding device 2 includes a base 21, a metal spring 22, and a metal protrusion 23. The base 21 has an assembly cavity 211, and the grounding terminal 13 is fixedly located within the assembly cavity 211. The metal protrusion 23 is movably located at the upper part of the assembly cavity 211. The metal spring 22 is located between the grounding terminal 13 and the metal protrusion 23, enabling an electrical connection between the metal protrusion 23 and the grounding terminal 13. The spring of the metal spring 22 allows the metal protrusion 23 to protrude or retract, ensuring reliable grounding.
[0024] Preferably, a tray portion 131 is formed radially enlarged on the grounding terminal 13 corresponding to the bottom position of the assembly cavity 211. The end of the metal spring 22 contacts the tray portion 131. The design of the tray portion 131 increases the contact area between the metal spring 22 and the grounding terminal 13, resulting in better electrical contact and improved grounding effect. A riveting hole is provided at one end of the neutral wire terminal 12 for inserting the wire core, which facilitates the insertion and fixing of the neutral wire core, simplifies the assembly process, improves production efficiency, and makes the connection more secure and reliable.
[0025] The head end of the metal convex cover 23 is hemispherical and slides smoothly with the grounding metal base. The lower end of the metal convex cover 23 is radially protruding to form a convex ring, which cooperates with the opening of the outer shell 15 to prevent it from falling off.
[0026] The base 21 has symmetrical barbs 211 on both sides, and the inner shell 14 has hook positions 145 that are adapted to the barbs 211. It is easy to assemble and has a good fit.
[0027] When using, please refer to Figure 5 The male connector body 3 in the figure has a notch 31 that matches the shape of the female connector body 1. The vertical surface of the notch 31 has a socket 32 that matches the insertion part 141. A grounding metal seat 33 is provided on the bottom plane of the notch 31 corresponding to the position of the grounding device 2. The grounding metal seat 33 has sliding hook feet 331 on both sides that match the sliding hook groove 144. The sliding hook feet 331 cooperate with the sliding hook groove 144 to ensure that the insertion part 141 can be accurately inserted into the socket 32. See also... Figure 6 When the plug part 141 is inserted into the socket 32, the grounding device 2 comes into contact with the grounding metal base 33 to achieve the purpose of grounding. This can effectively prevent the risk of electric shock caused by leakage, protect the personal safety of users, and improve the safety of use.
[0028] Meanwhile, since the shape and size of the plug part 141 remain unchanged, it can be directly adapted to the traditional male connector body 3. The grounding device 2 can be grounded by simply wiring or other means, which makes it highly versatile and applicable.
