Description

Technical Field

[0001] The utility model relates to the technology of Type-C male connector field, in particular to a stable Type-C male connector. Background Art

[0002] At present, the Type-C connector is widely used in electronic devices such as smartphones and laptops because it can be inserted in both directions. Unlike the old USB port, which can only transmit power in one direction, the Type-C connector transmits power in both directions. The Type-C connector can be used for charging, data transmission, etc.

[0003] In the prior art, a Type-C connector is disclosed, which includes an insulating seat, a terminal group, a hook member and a shielding shell. The insulating seat is provided with a plurality of plug-in slots for the terminal group and the hook member to be inserted. The terminal group and the hook member are both inserted into the corresponding plug-in slots. When the Type-C connector of this structure is welded and glued, the connection stability between the terminal of the terminal group and the plug-in slot is poor, and it is easy to shift in the plug-in slot, thereby affecting the welding and glue-wrapping work. In addition, under this structure, the glue directly adheres to the surface of the terminal. Since the terminal is made of metal, the connection stability between the glue and the terminal is poor. After multiple plugging and unplugging, the terminal is prone to PIN withdrawal, which in turn affects the service life of the Type-C connector.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0005] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a stable Type-C male connector, which is provided with a first convex-concave structure on the side of the fixed section of the grounding terminal and the power terminal. The fixed section is fixed to the base through the first convex-concave structure. The setting of the first convex-concave structure enables the grounding terminal and the power terminal to be firmly inserted into the plug-in slot, which can avoid displacement during welding and glue coating, and ensure that the welding and glue coating work of the Type-C male connector can be carried out smoothly. The rear end of the base is provided with a plurality of glue-containing grooves connected to the plug-in slots, and the fixed section is provided with a through hole exposed to the glue-containing groove. The setting of the through hole allows glue to enter the through hole, thereby improving the connection stability of the glue with the grounding terminal and the power terminal, and at the same time can play a blocking role to prevent the grounding terminal and the power terminal from PIN withdrawal.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0051] See Figure 4 and Figure 5 As shown, the rear end of the shielding shell 40 abuts against the front end of the base 12, and buckle plates 41 extend backward on both the upper and lower sides of the rear end of the shielding shell 40.
