[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to the following: Figures 1-10 This utility model provides a technical solution: a Type C 24-pin side-mount female connector, including a lower row of terminals 1, an upper row of terminals 2, a middle clip 3, a plastic part 9, an inner shell 4, and an outer shell 5. Both the lower row of terminals 1 and the upper row of terminals 2 are provided with terminal portions 6. The middle part of the terminal portion 6 is provided with a bent portion 7. The width of the terminal portion 6 at the bent portion 7 is smaller than the width of other positions. The GND terminals on both sides of the terminal portion 6 are widened. The width of the 2nd, 3rd, 10th, and 11th pins of the terminal portion 6 is smaller than the width of other pins. Specifically, by different SMT bending of the upper row of terminals 2 and the lower row of terminals 1, the high-speed transmission signal pins in the middle part of the terminal portion 6 of the upper row of terminals 2 and the lower row of terminals 1 are narrowed and bent, and the GND terminals on both sides of the terminal portion 6 are widened, which speeds up the charging efficiency and better avoids crosstalk. In addition, the width of pins 2, 3, 10, and 11 is narrowed to ensure charging efficiency and reduce crosstalk interference.

[0029] In this embodiment, the heads of both the upper row of terminals 2 and the lower row of terminals 1 are tilted at -5 degrees. Specifically, by tilting the heads of both the upper row of terminals 2 and the lower row of terminals 1 at -5 degrees, the terminal heads will not be warped when the male and female connectors are inserted. After the upper row of terminals 2 and the lower row of terminals 1 are molded, the terminals are pressed down into the interior of the plastic part 9 to prevent damage to the connector terminal heads, thereby making them more secure.

[0030] In this embodiment, two clearance holes 8 are provided on the outer surface of the middle clip 3, and a molding opening 16 is provided at the head of the middle clip 3. Specifically, pins 2, 3, 10, and 11 are avoided by the clearance holes 8, so as to better prevent crosstalk between the upper and lower row terminals 1. The molding opening 16 at the head of the middle clip 3 is intended to better integrate with the upper row terminal 2 and the lower row terminal 1 when molded.

[0031] In this embodiment, a second protrusion 12 for grounding with the outer shell 5 is provided on the outside of the intersection of the middle clip 3 and the plastic part 9mold. Specifically, the second protrusion 12 is provided to better ground with the outer shell 5.

[0032] In this embodiment, when the plastic part 9 is molded with the upper row of terminals 2 and the lower row of terminals 1 for the first time, it is provided with a first boss 10 and a groove 15. The first boss 10 and the groove 15 are used for positioning when the upper row of terminals 2 and the lower row of terminals 1 are molded with the middle clamp 3. Specifically, by using the first boss 10 and the groove 15, it is easier to position the upper row of terminals 2 and the lower row of terminals 1 when the middle clamp 3 is molded.

[0033] In this embodiment, a third boss 13 is provided at the rear of the plastic part 9 during the second molding process, and a round hole 17 is provided at the other part. Specifically, by providing the third boss 13, it is convenient to assemble, position and fix the plastic part 9 in the future. By providing the round hole 17, the purpose is to make the upper row of terminals 2 of the mold better positioned with the middle clip 3 and the lower row of terminals 1 of the mold more accurately.

[0034] In this embodiment, the middle clip 3 is provided with two protrusions 14 at the tail connecting strip. Specifically, by providing the two protrusions 14, it is better grounded to the upper row of terminals 2 and the lower row of terminals 1.

[0035] In this embodiment, two spring pieces 11 are provided on both the front and back of the inner shell 4. Multiple through slots for fixing the plastic part 9 are provided on the surface of the inner shell 4. Specifically, by providing multiple spring pieces 11, the inner shell 4 is better grounded with the outer shell 5, and multiple through slots are provided on the surface of the inner shell 4 to engage with the protrusions on the surface of the plastic part 9, thus preventing the inner shell 4 from becoming loose from the plastic part 9.

[0036] In this embodiment, the outer shell 5 has a plurality of square holes and elongated cylindrical grooves for connecting with the plastic part 9. Specifically, by starting the square holes and elongated cylindrical grooves on the surface of the outer shell 5 and engaging with the protrusions on the surface of the plastic part 9, loosening between the outer shell 5 and the molded plastic part 9 is avoided.

[0037] Working Principle: During molding and assembly, the upper row of terminals 2 and the lower row of terminals 1 are molded and then pressed down into the interior of the plastic part 9 to prevent damage to the connector terminal heads, thus making them more secure. When the middle clip 3 is molded with the upper row of terminals 2 and the lower row of terminals 1, it is fixed to the terminal portion 6 of the upper row of terminals 2 and the lower row of terminals 1 through the clearance hole 8, which plays a more stable and secure role. Furthermore, the clearance hole 8 avoids pins 2, 3, 10, and 11, better preventing crosstalk between the upper and lower rows of terminals 1. The molding opening 16 at the head of the middle clip 3 is designed to better integrate with the upper row of terminals 2 and the lower row of terminals 1 during molding. The outer edge of the junction between the middle clip 3 and the plastic part 9 during molding... The inner shell 4 and outer shell 5 are provided with a second protrusion 12 to better ground with the outer shell 5. After the first molding of the plastic part 9, a groove 15 and a first protrusion 10 are left inside the plastic part 9 during the first molding to facilitate better positioning when the middle clip 3 is added to the upper row terminal 2 and the lower row terminal 1. After the second molding of the plastic part 9, a third protrusion 13 is designed to facilitate subsequent assembly positioning and fixation. The purpose of opening a round hole 17 is to make the upper row terminal 2 of the molding better positioned with the middle clip 3 and the lower row terminal 1 of the molding more accurately. After three moldings, the inner shell 4 and outer shell 5 are assembled together, and then the inner shell 4 and outer shell 5 are welded together by laser spot welding, which is more solid.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
