Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail. the

As shown in Figures 1A~1B, the integrated waterproof connector 100 of the present invention mainly integrates two or more connectors (such as a USB connector 10 and an audio connector 11) in an independent body, and includes more than two Plastic body 3a, 3b, is arranged on each plastic body 3a, 3b between the colloid connection part 6, is fixed on the inside of each plastic body 3a, 3b a terminal 8a, 8b, covers each plastic body 3a, 3b Open sealing covers 4a, 4b, and a hold down 7 covering the glue joint 6 and each plastic body 3a, 3b. Wherein, the outer surfaces of the plastic bodies 3a, 3b which are hollow tubular bodies respectively define an upper surface and side surfaces, while the outer surfaces of the solid colloid connecting part 6 define an upper surface and side surfaces respectively. the

Please refer to FIG. 2, which is a schematic diagram of the plastic body of the present invention. As shown in FIG. 2, the openings at both ends of the plastic bodies 3a, 3b are respectively defined as plug openings 31a, 31b and terminal openings 32a, 32b. The inner edge contour structure of the plug openings 31a, 31b of the plastic body 3a, 3b is respectively relative to the USB plug and the audio plug connector, and at the same time, the inner edge contour structure of the plug opening 31a also relatively covers the contour structure of the metal shell 2, so as to cover the metal shell 2 can fit inside the plastic body 3a. The inner edge profile of the terminal openings 32a, 32b is slightly larger than the edge profile of the plug openings 31a, 31b. the

Please refer to FIG. 3 . FIG. 3 is a schematic diagram of the fixing bracket of the present invention. As shown in FIG. 3 , the fixing bracket 7 includes a bracket body 70 and a plurality of side brackets 71 vertically extending from the bracket body 70 . The bracket body 70 can be covered on the upper surface of each plastic body 3a, 3b and the colloidal connection part 6, and each side bracket 71 can be respectively covered on the side surfaces of each plastic body 3a, 3b and the colloidal connection part 6 . the

As shown in Fig. 2 and Fig. 3, in order to allow the plastic body 3a, 3b to be closely combined with the fixed bracket 7, the side surfaces of the plastic body 3a, 3b further have a first fixing portion 33, while the side bracket 71 of the fixed bracket 7 has The structure is opposite to the second fixing part 711 . After the plastic bodies 3 a , 3 b are tightly combined with the fixing bracket 7 , the fixing portion 712 is extended from the end of the side bracket 71 of the fixing bracket 7 , so that the entire connector is installed on the circuit board. A terminal slot 34 is provided inside the plastic body 3b for installing the terminal 8b. the

In this way, when installing the integrated waterproof connector 100, only one opening needs to be opened on the housing of the electronic device, and only one-time installation is required, so that the electronic device can provide more than two types of connectors (such as the USB connector 10 and audio connector 11), and at the same time utilize waterproof designs such as sealing covers 4a, 4b to prevent moisture from invading into the electronic device through the connector. However, the internal structure of the USB connector 10 is different from that of the audio connector 11 , so different considerations are required in waterproof design, especially for the USB connector 10 with a more complex structure. the

As shown in FIG. 1B , the additional components required by the USB connector 10 include a terminal module 1 and a shielding metal shell 2 . The terminal module 1 can be inserted through the opening of the shielding metal shell 2 to form an assembly as shown in FIGS. 4A-4B , and then installed together into the plastic body 3 a to form an assembly as shown in FIG. 5A . Among them, the terminal module 1 includes a solid colloid 13, a terminal contact portion 14 extending vertically from the solid colloid 13, a metal reinforcement sheet 9 covering the terminal contact portion 14, and a plurality of terminals 8a fixed by the solid colloid 13 (such as Figure 5C). The shielding metal shell 2 has a grounding arm 23 (as shown in FIG. 5C ), so that the shielding metal shell 2 can be grounded, thereby providing a shielding effect. the

Among them, in order to improve the structural strength of the terminal contact portion 14 of the USB connector 10 and prevent the terminal contact portion 14 from breaking, the metal reinforcement sheet 9 attached to the terminal contact portion 14 can achieve this purpose. However, in practice, the metal reinforcing sheet 9 and a plurality of terminals 8 can be overmolded by the solid colloid 13 and the terminal contact portion 14 at the same time by means of injection molding, or only the metal reinforcing sheet 9 can be covered by a solid The glue 13 is overmolded, and then a plurality of terminals 8 are inserted into the interior of the terminal contact portion 14 . No matter what method is used to make the terminal module 1, the appearance shape of the metal reinforcing sheet 9 is relative to the solid gel 13 and the terminal contact portion 14. At the same time, the metal reinforcing sheet 9 is only covered by the solid gel 13, but it is also covered Outside the terminal contact portion 14 . the

However, if the metal reinforcing sheet 9 close to the signal terminal is not grounded, the metal reinforcing sheet 9 will be a suspended conductor, and crosstalk (crosstalk) and resonance are prone to occur during high-speed transmission, and the metal reinforcing sheet 9 is structurally Patch 9 will also be the same as a patch antenna (Patch Antenna) and has the problem of Electro Magnetic Interference (EMI) caused by electromagnetic wave radiation. In other words, if the metal reinforcing piece 9 is not grounded, it will cause signal integrity (Signal Integrity, SI) and EMI problems. the

Please refer to FIGS. 4A-4B . FIGS. 4A-4B are schematic diagrams illustrating the combination of the shielding metal shell and the terminal module of the present invention. Wherein, FIG. 4B is a schematic diagram of a part of the perforated hole in FIG. 4A. As shown in Figures 4A to 4B, in order to provide the rear shielding function, a shielding metal layer 49 is formed on the surface of the cover body 40 of the sealing cover 4a, and when the sealing cover 4a is covered on the terminal opening 32a, the sealing cover 4a The shielding metal layer 49 is in contact with the shielding metal shell 2, and the shielding metal layer 49 is also grounded to provide a shielding effect.

As shown in Figures 1A-1B, in order to improve the waterproof ability, the gap between each terminal 8a, 8b, the gap between the sealing cover 4a, 4b and the edge profile structure of the terminal opening 32a, 32b is covered with waterproof adhesive material 5a, 5b Filled to prevent water vapor from entering the electronic device through the gap of the connector. the
