[0028] Please refer to Figures 1 to 6 , the present utility model is a plug connector, which includes a plug 1 and a socket 2 that docks with the plug 1.

[0029] Please refer to Figures 1 to 4, the plug 1 includes a first plug plastic part 11, a plug terminal 12 connected to the first plug plastic part 11, and a second plug plastic part 13 that wraps the first plug plastic part 11 and the plug terminal 12. The first plug plastic part 11 includes a first annular body 111 and a plurality of slots 112 integrally formed with the first annular body 111. The first annular body 111 is in a hollow state. The slots 112 are vertically recessed upward from the lower surface of the first annular body 111 and penetrate both the inner and outer sides of the first annular body 111. Their shapes match the shape of the plug terminal 12. In this embodiment, the slots 112 are rectangular grooves and are distributed around the center of the first annular body 111, and their number can be changed according to requirements.

[0030] Please refer to Figure 2 to Figure 3. The outer surface of the first annular body 111 has a protrusion 113. One end of the protrusion 113 is fixedly connected to the first annular body 111, and the other end extends outward. The protrusion 113 is provided on both sides of the slot 112 and extends vertically downward along the outer surface of the first annular body 111 from the top of the slot 112. Its length can be changed according to the length of the plug terminal 12. The protrusion 113 is used to support the plug terminal 12 to make the position of the plug terminal 12 closer to the socket 2. Preferably, the diameter of the end of the protrusion 113 fixedly connected to the first annular body 111 is larger than the end of the protrusion 113 that extends outward.

[0031] The inner surface of the first annular body 111 has a positioning part 114. The positioning part 114 is annular and extends along the inner surface of the first annular body 111. The positioning part 114 has a plurality of positioning holes 115. The plurality of positioning holes 115 respectively penetrate the upper and lower surfaces of the positioning part 114. The plurality of positioning holes 115 are distributed around the center of the first annular body 111 and correspond to the slots 112 one by one. Preferably, a reinforcing rib 116 is provided on the lower surface of the positioning part 114. One side of the reinforcing rib 116 is fixedly connected to the first annular body 111, and the other side is fixedly connected to the positioning part 114.

[0032] The plug terminal 12 is made of a certain conductive metal material, and its number can be changed according to requirements and corresponds to the slots 112 one by one. A part of the plug terminal 12 is C-shaped and buckled on the protrusion 113, and the other part extends into the slot 112 and fits on the lower surfaces of the first annular body 111 and the positioning part 114, and its end extends vertically through the positioning hole 115.

[0033] When the plug 1 is molded, the plug terminal 12 is first inserted and cooperatively installed with the first plug plastic part 11, and then placed in a mold for secondary injection molding so that the second plug plastic part 13 wraps the first plug plastic part 11 and the plug terminal 12.

[0034] Please refer to Figure 4, the second plug plastic part 13 is an integrally formed ring-shaped plastic part, which is on the same axis as the first plug plastic part 11. A cavity 131 is formed inside the second plug plastic part 13. The cavity 131 is used to accommodate the first plug plastic part 11 and the plug terminal 12. The second plug plastic part 13 is provided with a number of first windows 132. The number of first windows 132 is formed by being recessed inward from the outer surface of the second plug plastic part 13 and communicating with the cavity 131. They are distributed around the center of the second plug plastic part 13 and correspond to the plug terminals 12 one by one. A part of the plug terminal 12 buckled on the convex part 113 is exposed outside the first window 132. There are a number of docking grooves 133 on the inner side of the second plug plastic part 13. The number of docking grooves 133 is formed by being recessed inward from the inner surface of the second plug plastic part 13 and communicating with the cavity 131. They are distributed around the center of the second plug plastic part 13. One end of the plug terminal 12 passing through the positioning hole 115 penetrates through the docking groove 133 to dock with other components.

[0035] Please refer to Figures 5 to 6 , the socket 2 includes a socket plastic part 21 and socket terminals 22 installed in the socket plastic part 21. The socket plastic part 21 includes a second ring-shaped body 211. The second ring-shaped body 211 is in a hollow state, and its diameter is larger than the diameter of the first ring-shaped body 111. The second ring-shaped body 211 has a receiving cavity 212 penetrating its upper and lower surfaces and a second window 213 communicating with the receiving cavity 212. The receiving cavity 212 is distributed around the center of the second ring-shaped body 211 and is used to receive the socket terminals 22. The space of the receiving cavity 212 changes according to the size of the socket terminals 22. Clamping grooves 214 are provided at both the top and the bottom of it. The clamping grooves 214 respectively fix the upper and lower ends of the socket terminals 22, so that the socket terminals 22 are stably installed in the socket plastic part 21.

[0036] The second window 213 is formed by being recessed inward from the inner surface of the second ring-shaped body 211 and communicating with the receiving cavity 212. Its length changes according to requirements. A part of the socket terminal 22 extends out of the second window 213. When the plug 1 and the socket 2 are docked, the plug 1 extends into the socket 2, and the plug terminal 12 exposed outside the first window 132 abuts against the socket terminal 22 exposed outside the second window 213. At the same time, the socket terminal 22 can deform into the receiving cavity 212 to adapt to the plug 1.

[0037] When the plug connector of the present utility model is formed, the plug terminal 12 is first inserted and cooperatively installed with the first plug plastic part 11, and then put into a mold for secondary injection molding, so that the second plug plastic part 13 wraps the first plug plastic part 11 and the plug terminal 12. The socket 2 is inserted and cooperatively installed with the formed socket plastic part 21. When the plug 1 and the socket 2 are docked, the plug 1 extends into the socket 2, and the plug terminal 12 exposed outside the first window 132 abuts against the socket terminal 22 exposed outside the second window 213.

[0038] The utility model relates to a plug connector, which has the characteristics of firmness and stability. First, the plug terminal is inserted and cooperatively installed with the first plug plastic part, and then the second plug plastic part wraps the first plug plastic part and the plug terminal, and the plug terminal is exposed through the first window to abut against the socket terminal exposed through the second window of the socket plastic part, increasing the contact area between the plastic part and the terminal and improving the structural stability of the product.

[0039] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution and the inventive concept of the utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the utility model.
