[0034] This embodiment provides a connector terminal structure, which includes: a wire body 11, an inner molded body 12, an outer molded body 13, a fixed frame 14, a lifting rod 15, and a plug body 16. The plug body 16 is used to connect with a socket 17, and the socket 17 is fixedly installed on the corresponding product.

[0035] One end of the line body 11 is connected to the plug body 16. The inner mold colloid 12 is injection molded and connected to the outer periphery of the line body 11 and to one side of the plug body 16. The inner mold colloid 12 achieves a fixed connection between the line body 11 and the plug body 16 through injection molding, resulting in a stable structure.

[0036] The fixed frame 14 is sleeved on the outer periphery of the inner mold 12. A connecting groove 141 is provided through the fixed frame 14 and extends through the side of the fixed frame 14 so that the adapter post 151 of the lifting rod 15 can slide into the connecting groove 141.

When the lifting rod 15 is in the extrusion position, the adapter post 151 and the socket 17 are at a second set distance apart. The second set distance is greater than the first set distance. The lifting rod 15 rotates and presses the socket 17 to slide away from the plug body 16, so that the connecting wire terminal structure can be pulled out from the socket 17.

[0040] Please refer to Figure 2 In this embodiment, a first fixing groove 161 is provided on the outer periphery of one end of the plug body 16, and a first protruding edge strip is provided on the inner side of the inner mold colloid 12 to fill the first fixing groove 161, so that the inner mold colloid 12 and the plug body 16 are stably connected.

[0043] The inner mold 12 has a recessed groove 123 on both sides of the mounting groove 122. The recessed groove 123 is connected to the mounting groove 122. The inner side of the outer mold 13 has a protrusion that fills the recessed groove 123. The protrusion is integrally formed when the outer mold 13 is injected. The protrusion can limit and fix the limiting plate 18.

[0044] In this embodiment, the limiting plate 18 is made of polypropylene thermoplastic, which has good tensile strength and rigidity. The plug body 16 is made of a composite material of polyamide 66 thermoplastic resin and 30% glass fiber, which has high strength and good rigidity.

[0046] In this embodiment, a limiting block 131 is provided on the side of the outer mold 13 to limit the rotation range of the lifting rod 15. The line 11 extends from one side of the outer mold 13 along a direction perpendicular to the sliding trajectory of the socket 17. The rotation range of the lifting rod 15 is limited between the limiting block 131 and the line 11.

[0047] When the lifting rod 15 is in the initial position, it is in contact with the cable 11. At this time, the end of the lifting rod 15 can be in contact with the socket 17 or at a set distance from the socket 17. The end of the lifting rod 15 may be provided with some smooth structure to facilitate compression with the socket 17.

[0048] When the lifting rod 15 is in the extrusion position, the lifting rod 15 contacts the limiting block 131. At this time, the end of the lifting rod 15 contacts the socket 17, and the lifting rod 15 has pressed the socket 17 and slid it away from the plug body 16 by a set stroke length.

[0049] Please refer to Figure 2 and Figure 3In this embodiment, an elastic plate 171 is provided on the inner wall of the socket 17. A limiting protrusion 172 is provided on the side of the elastic plate 171 near the plug body 16. A limiting groove 163 is provided on the outer wall of the plug body 16.

[0050] In this embodiment, one end of the outer mold colloid 13 is provided with an extension 132 that wraps around the thread 11, which improves the connection stability between the outer mold colloid 13 and the thread 11 and makes the connection between the thread 11 and the outer mold colloid 13 less prone to damage.

[0051] When using the connection terminal structure of this utility model, first rotate the lifting rod 15 to contact the wire body 11, and then insert the plug body 16 and the socket 17. During the insertion process, the socket 17 will be squeezed and slide towards the inner mold colloid 12.

[0052] When it is necessary to remove the connecting wire terminal structure from the terminal socket, the lifting rod 15 can be rotated to contact the limit block 131. During the rotation of the lifting rod 15, the socket 17 will be squeezed and slid away from the plug body 16, making it easier for the plug body 16 to be removed from the socket 17.

[0053] In this preferred embodiment, the connector terminal structure first connects the inner mold body to the plug body through a first injection molding process, and then connects the outer mold body to the inner mold body through a second injection molding process. This can confine the fixing frame between the outer mold body and the plug body, while stabilizing the connection between the lifting rod and the fixing frame. When the lifting rod rotates, it presses the socket to slide away from the plug body, making it easy to pull the connector terminal structure out of the socket.

[0054] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention.
