Among them, the Type-C plug 41 is an integrally formed waist-shaped closed structure with openings at both ends.

[0027] A Type-C connector with a plastic shell and rubber coating structure provided in an embodiment of the present invention includes a connector plastic shell 11 and a Type-C connector assembly 2, that is, its connector plastic shell 1 is a plastic shell and rubber coating structure, and the connector adopts a plastic shell and mold inner rubber coating structure. The inner mold is rubber coated once to fix the Type-C connector and the circuit part into a module, and then the shielding cover is assembled. The inner mold is rubber coated for a second time to wrap the semi-finished product with the shielding cover 5. After the secondary rubber coating is completed, it is pre-fixed in the connector plastic shell 1, and then the glue is poured to form a glue pouring structure 3. After the cavity is completely filled with the glue pouring structure 3, the connector part and the connector plastic shell 1 form a stable combination.

[0028] The glue-filling structure 3 is an integrated structure formed by injection molding inside the connector plastic shell 1 after the Type-C connector component 2 is installed inside the connector plastic shell 1, which is beneficial to improving the production efficiency.

[0029] The glue-filling structure 3 is a shell structure, and an open end on one side of the shell structure is used to extend the Type-C plug 41 , and an open end on one side of the shell structure is used to connect a coaxial cable 43 .

[0030] A through hole 11 is provided on one side surface of the connector plastic shell 1, that is, a glue-pulling through hole structure is designed for filling glue into the interior of the connector plastic shell 1. After the secondary injection inner mold 6 is installed in the connector plastic shell 1, other gaps in the connector plastic shell 1 are completely filled, so that the connector and its shell part are more stably combined, that is, after glue pouring, the inner cavity of the connector plastic shell 1 is filled and the inner mold is wrapped. After the cavity is completely filled with glue, the connector part and the connector plastic shell 1 form a stable combination.

[0031] The upper surface of the glue pouring structure 3 is provided with a raised connection portion 44, and the raised connection portion 44 is arranged at the through hole, so that the connector plastic shell 1 is tightly connected to the Type-C connector assembly 2 through the glue pouring structure 3.

[0032] The inner wall of the connector plastic shell 1 is provided with a plurality of installation limit ribs 12 with guide angles, which are used to pre-fix the Type-C connector assembly 2, so that the outward extension length of the Type-C plug 41 meets the preset plug-in standard. In the pre-fixed installation structure formed in this embodiment, the shielding cover 5 is assembled after the Type-C connector and the cable are welded, and then the semi-finished product is made by in-mold injection molding. The semi-finished product is installed in the connector plastic shell 1, and the internal ribs of the connector plastic shell 1 form a precise positioning, which not only ensures that the Type-C extension length meets the plug-in standard, but also avoids the displacement of the connector caused by the pressure applied during the glue filling.

[0033] The connector plastic shell 1 is an integrally formed injection-molded structural component, which includes a first shell portion 14 and a second shell portion 13 with a buckle portion. The first shell portion 14 is a shell structure with two ends open, and the buckle portion is provided at the upper end of the second shell portion 13. The lower end of the second shell portion 13 is adapted to the buckle portion to form a groove structure extending out of the Type-C plug 41, which is conducive to improving production efficiency. At the same time, the connector plastic shell 1 is made of hard plastic material as a connector shell to improve the overall strength and not easily deform.

[0034] The elastic snap mechanism 7 includes a first connecting portion 71, a first elastic arm 72, a second elastic arm 73, and a second connecting portion 74 which are arranged in sequence and at intervals to form a snap-on groove connected to the female socket. The first elastic arm 72 and the second elastic arm 73 are fixedly connected to form an elastic pressing portion 75.

The first connecting portion 71 and the second connecting portion 74 are both L-shaped structures, and the L-shaped structures are both provided with a limiting portion 76 extending along the width direction of the connector plastic shell 1 for limiting the CPA structure 8; the elastic pressing portion 75 is provided with an extension portion 77 adapted to the CPA structure 8 along the width direction of the connector plastic shell 1 for moving the CPA structure 8 under the elastic pressing portion 75, so that the elastic pressing portion 75 locks the connector and the female socket through the CPA structure 8. It can be understood that the connector plastic shell 1 has an elastic wall buckle, which is locked with the female socket after installation. The female socket is a structure that matches the connector (not shown in the figure). After the CPA structure 8 is installed, the elastic arm of the connector plastic shell is supported to completely lock the male and female sockets to avoid easy disconnection during use.

[0035] One or more guide blocks 15 are provided on the inner wall or outer surface of the connector plastic shell 1. In this embodiment, multiple guide blocks 15 are distributed on the inner wall of the connector plastic shell 1 to facilitate the installation of the connector assembly; multiple guide blocks 15 are provided on both sides of the surface of the connector plastic shell 1 to facilitate installation with the female socket, and play a guiding role in the installation of the connector assembly into the connector plastic shell 1 or the Type-C connector and the female socket.
