Description

Technical Field

[0001] The present application relates to a waterproof USB Type C socket connector. Background Art

[0002] USB 3.1 is the latest USB specification, which was initiated by Intel and other large companies. The data transmission speed can be increased to 10Gbps. Compared with the traditional USB 2.0 technology, the new USB technology uses a more efficient data encoding system and provides more than double the effective data throughput. USB 3.1 includes three types: Type-A, Type-B and Type-C. In December 2013, the USB 3.0 promotion team announced the rendering of the next-generation USB Type C connector, and then in August 2014, it was ready for mass production. The highlights of the new version of the connector are a slimmer design, faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W). The biggest advantage is that it supports front and back insertion, which solves the problem of "USB can never be inserted correctly", and can be inserted in any way.

[0003] For the related prior art, please refer to Chinese utility model patent CN218632595U, which discloses a USB Type C waterproof connector, which mainly realizes waterproofing of the gap between the metal front shell 30 and the connector body 10 and the conductive terminal 12 by filling the waterproof colloid 20 in the slot 114 of the insulator 11. However, since the waterproof colloid 20 is surrounded and clamped by the sleeve 31, the waterproof colloid 20 is closed by the metal front shell 30. The specification also introduces that: the waterproof colloid 20 is solidified by liquid silicone. Since the silicone has a large fluidity, the glue will flow into the cracks of the insulator 11, the gaps between the insulator 11 and the conductive terminal 12, and the gaps between the insulator 11 and the middle spacer 13. After the gaps are fully filled, the waterproof effect of the inside of the connector body 10 can be achieved. However, in the actual production process, the waterproof colloid 20 is not easy to be implanted.

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

The fixing section 22 of each terminal piece 2 includes a sealing section 221 exposed in the waterproof groove 101. Preferably, the entire periphery of each sealing section 221 is exposed in the waterproof groove 101.

[0054] Furthermore, the shielding inner shell 3 includes a rear section 31, a front section 32, and a connecting portion 33 connecting the rear section 31 and the front section 32. The rear section 31 is arranged in a ring shape around the outer periphery of one end of the base 11 close to the tongue root 12, the waterproof groove 101 is surrounded by the rear section 31, the implantation groove 102 is at least partially not closed by the rear section 31 upward to form an implantation port 1021, and the front section 32 is arranged around the outer periphery of the tongue root 12. A preferred embodiment is that the rear section 31 covers and crosses the waterproof groove 101 along the insertion direction of the docking connector, and the waterproof groove 101 does not expose the rear section 31 along the up and down direction. A preferred embodiment is that the shielding inner shell 3 is formed by a metal plate or a metal tube through a stretching and drawing process, and the rear section 31 has no seams along the circumferential direction.

[0055] Please refer to 2 to Figure 6As shown, the connection portion 33 of the shielding inner shell 3 is annular and corresponds to the front end surface of the base 11. The front section 32 is correspondingly arranged around the outer surface of the tongue root portion 12. In the embodiment of the present application, the shielding inner shell 3 is assembled and sleeved on the insulating body portion 1 along the insertion direction of the docking connector. A preferred embodiment is that the front section 32 is formed with reserved seams 320 at two side positions of the tongue root portion 12, so that the front section 32 is divided into an upper cover 321 and a lower cover 322.

Both sides of the base 11 are formed with fixed ears 114 extending in the transverse direction, and the reinforcing ears 52 are buried in the fixed ears 114. The waterproof USB Type C socket connector is also formed with a locking hole 104 penetrating the fixed ears 114 and the reinforcing ears 52 in the vertical direction. Furthermore, the middle partition 5 is also formed with an extension piece 54, which is formed by bending and extending the main body 51. The extension piece 54 is exposed from the upper surface or lower surface of the tongue root 12 and is attached to the inner surface of the front section 32 and fixed by welding.

[0057] Please refer to Figures 4 to 7As shown, the inner bottom surface of the implantation groove 102 forms an inclined surface 1022, so that the depth of the implantation groove 102 in the up-down direction gradually expands along the removal direction of the docking connector. The waterproof groove 101 surrounds the inner annular surface of the rear section 31 for a whole circumference. The waterproof USB Type C socket connector also includes a waterproof colloid 4, which includes a first part 41 filled into the waterproof groove 101 and a second part 42 filled into the implantation groove 102. In the actual production process, the waterproof colloid 4 is preferably a waterproof glue with fluidity, and the waterproof colloid 4 is injected through the implantation port 1021 and flows into the waterproof groove 101 through the implantation groove 102. In a preferred embodiment, the waterproof colloid 4 fills the gap between the rear section 31 and the base 11; the waterproof colloid 4 fills the gap between the connecting portion 33 and the front end surface of the base 11; the waterproof colloid 4 fills the gap between the front section 32 and the tongue root 12. In addition, the first part 41 of the waterproof colloid 4 fills and adheres to the inner annular surface of the rear section 31 for a whole circumference. A preferred embodiment is that the waterproof colloid 4 fills the implantation groove 102 and the waterproof groove 101. The inclined surface 1022 is used to guide the flow of the waterproof colloid 4, and can also make the channel cross-section at the connection position of the implantation groove 102 and the waterproof groove 101 larger, which is conducive to the flow of the waterproof colloid 4.

[0058] The waterproof USB Type C socket connector of the present application can be directly inserted and assembled into the interior of an electronic device, and a cavity is formed through the housing of the electronic device, and the tongue root portion 12 and the tongue end portion 13 are correspondingly inserted into the cavity, and together define a docking cavity for the docking connector to be inserted. In order to ensure the tightness of the assembly between the waterproof USB Type C socket connector of the present application and the electronic device, an elastic gasket 6 is also sleeved on the outer circumferential surface of the rear section 31.

[0059] Please refer to Figure 8 As shown, in order to achieve better waterproof performance, a rough surface 310 is formed on the inner wall surface of the rear section 31 of the shielding inner shell 3 by processing. The rough surface 310 surrounds the inner wall surface of the rear section 31 for a whole circumference, and can be, for example, a pitted, serrated surface structure, or an embossed structure. The rough surface 310 can increase the tightness of the combination with the waterproof colloid 4, and at the same time can increase the holding force with the outer surface of the base 11. The outer peripheral surface of the waterproof colloid 4 is also matched to form a rough surface structure 40. Through the implementation of the present application, better waterproof performance can be achieved, and the waterproof colloid 4 can be more easily implanted during the product production process.
