[0019] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0020] Please refer to Figures 1 to 4 A one-step molded Type-C connector female seat includes a shell 10, an injection molded body 20 is fixedly arranged in the shell 10, that is, the shell 10 covers the injection molded body 20, and an upper row of terminals 30, a middle clamping plate and a lower row of terminals 50 are stacked on the injection molded body 20 in sequence. The upper row of terminals 30, the middle clamping plate and the lower row of terminals 50 are integrally injection molded with the injection molded body 20, which simplifies the manufacturing process and improves production efficiency and product yield. Specifically, the injection molding body 20 includes a base 21 and a tongue plate 22 connected to each other, the upper row terminal 30 includes an upper contact portion 31, an upper connecting portion 32 and an upper welding portion 33 connected in sequence, the upper contact portion 31 is embedded in the upper surface of the tongue plate 22, and the upper contact portion 31 protrudes from the upper surface of the tongue plate 22, the upper connecting portion 32 is embedded in the base 21, and the upper welding portion 33 extends out of the base 21 away from the tongue plate 22. The lower row terminal 50 includes a lower contact portion 51, a lower connecting portion 52 and a lower welding portion 53 connected in sequence. The lower contact portion 51 is embedded in the lower surface of the tongue plate 22, and the lower contact portion 51 protrudes from the lower surface of the tongue plate 22, the lower connecting portion 52 is buried in the base 21, and the lower welding portion 53 extends out of the base 21 away from one end of the tongue plate 22. The upper contact portion 31 and the lower contact portion 51 are vertically arranged side by side for easy connection with an external connector, the upper connecting portion 32 and the lower connecting portion 52 are horizontally staggered for easy injection molding operations, and the upper welding portion 33 and the lower welding portion 53 are vertically arranged side by side for easy welding with an external circuit board.

[0021] Please refer to Figure 3 and Figure 4 An upper guide portion 34 is extended from one end of the upper contact portion 31 away from the upper connecting portion 32, and a lower guide portion 54 is extended from one end of the lower contact portion 51 away from the lower connecting portion 52. Both the upper guide portion 34 and the lower guide portion 54 are buried in the tongue plate 22. Specifically, both the upper guide portion 34 and the lower guide portion 54 are Z-shaped, and the upper guide portion 34 and the lower guide portion 54 are transversely staggered.

[0022] In the above scheme, the upper guide portion 34 forms a step with the upper contact portion 31, and the lower guide portion 54 also forms a step with the lower contact portion 51, and the upper guide portion 34 and the lower guide portion 54 are completely covered by the tongue plate 22, which can prevent the terminals from being damaged by impact during the plugging and unplugging of the connector. At the same time, the upper guide portion 34 and the lower guide portion 54 are vertically staggered, that is, the upper guide portion 34 and the lower guide portion 54 do not overlap in the vertical direction, which facilitates the injection molding operation of the tongue plate 22.

[0023] Please refer to Figures 2 to 4 The middle splint includes two splint bodies 40, which are symmetrically buried on both sides of the tongue plate 22. Further, a reinforcement through hole 41 is opened on the surface of the splint body 40, and a hook 42 is provided on the side wall of the splint body 40, and the hook 42 extends out of the side wall of the tongue plate 22.

[0024] In the above solution, the injection plastic passes through the reinforcement through hole 41 during the injection molding process, making the connection between the clamp body 40 and the injection molded body 20 more stable. In addition, the hook 42 can clamp the external connector to improve the stability of the connection, and is more wear-resistant than plastic, extending the plug-in life. Specifically, the clamp body 40 is made of hard metal.

[0025] In this embodiment, the number of the upper row of terminals 30 and the number of the lower row of terminals 50 are both eight, and the upper row of terminals 30 and the lower row of terminals 50 form a 16-pin Type-C electrical connector.

[0026] The utility model provides a one-time molded Type-C connector female seat. An upper row of terminals, a middle clamping plate and a lower row of terminals are formed by stamping with a hardware mold and are stacked in sequence from top to bottom. A contact portion of the upper row of terminals and a contact portion of the lower row of terminals are arranged vertically side by side, which is convenient for connection with an external connector after injection molding. An upper connecting portion and a lower connecting portion are arranged in a horizontally staggered manner, which is convenient for injection molding operations. An upper welding portion and a lower welding portion are arranged side by side, which is convenient for welding with an external circuit board. A middle clamping plate is arranged between the upper row of terminals and the lower row of terminals to isolate the upper row of terminals from the lower row of terminals. After the upper row of terminals, the middle clamping plate and the lower row of terminals are stacked in sequence, they are fixed on an injection molded body by a one-time inlay molding method, which simplifies the manufacturing process, improves production efficiency and product yield, and finally covers the injection molded body with a shell.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
