[0028] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the utility model, including an insulating body 10, a plurality of conductive terminals 20 and a shielding shell 30.

[0029] The insulating body 10 includes a base 11 and a tongue plate 12 extending from the base 11. In this embodiment, the insulating body is made of plastic. Also, the insulating body 10 is vertically arranged to form a vertical connector structure. In addition, an EMC housing 40 is sleeved on the front end of the base 11.

[0030] The plurality of conductive terminals 20 are all disposed on the insulating body 10, and each conductive terminal 20 has a contact portion 21 and a welding portion 22, wherein the contact portion 21 is exposed on the surface of the tongue plate 12, and the welding portion 22 is extended out of the base 11. In this embodiment, the plurality of conductive terminals 20 are disposed in two rows, and the plurality of conductive terminals 20 are all fixed on the insulating body 10 by inlay molding, and a middle clip 50 is fixed in the insulating body 10 by inlay molding, and the middle clip 50 is located between the two rows of conductive terminals 20. Furthermore, the welding portions 22 of the plurality of conductive terminals 20 are arranged side by side and spaced apart from each other and extend horizontally, so as to be fitted and welded with the circuit board for installation.

[0031] The shielding shell 30 is covered on the outside of the insulating body 10, and a waterproof ring 60 is arranged on the outer peripheral side of the front end of the shielding shell 30. The front end surface of the waterproof ring 60 is convexly provided with a first sealing ring portion 61 for tightly fitting with the front inner wall of the mounting hole 71 of the panel 70, and the internal pressure interference of the first sealing ring portion 61 is 0.15mm. The outer peripheral side of the waterproof ring 60 is convexly provided with a second sealing ring portion 62 for tightly fitting with the inner peripheral side wall of the mounting hole 71 of the panel 70, and the peripheral side interference of the second sealing ring portion 62 is 0.15mm. Specifically, the shielding shell 30 includes an inner shell 31 and an outer shell 32. The inner shell 31 is a seamless stretched shell, and the inner shell 31 is sleeved on the outside of the insulating body 10. The outer shell 32 is a stamped shell, and the outer shell 32 is sleeved on the outside of the inner shell 31. The waterproof ring 60 is sleeved on the front end of the inner shell 31 and abuts against the front end surface of the outer shell 32. The structure is simple, the assembly is convenient, and the waterproof effect is good. Furthermore, the outer shell 32 is fixed to the inner shell 31 by spot welding, and the assembly is simple and stable. A plurality of fixing solder pins 301 extend backward from the rear end of the outer shell 32, and the plurality of fixing solder pins 301 are arranged at intervals around the periphery, so that the product can be better installed and fixed to the circuit board. In addition, the inner shell 31 and the outer shell 32 are both iron shells.

[0032] The method of using this embodiment is described in detail as follows:

[0033] When in use, the product is placed vertically on a circuit board, and a plurality of fixing solder legs 301 are inserted into corresponding fixing holes on the circuit board for soldering and fixing, and at the same time, each soldering portion 22 is pressed against the corresponding solder pad of the circuit board for soldering and conduction.

[0034] When mounted with the panel 70 of the external chassis, as Figure 3 As shown, the panel 70 has a mounting hole 71 and a plug hole 72, the plug hole 72 is located at the front side of the mounting hole 71, and the inner diameter of the plug hole 72 is smaller than the inner diameter of the mounting hole 71. The front end of the shielding shell 30 is inserted into the mounting hole 71 from the rear side of the panel 70. After being inserted into place, the first sealing ring portion 61 fits tightly with the front inner wall of the mounting hole 71, and the second sealing ring portion 62 fits tightly with the inner peripheral side wall of the mounting hole 71 to form a good waterproof sealing structure. At this time, the circuit board and the panel 70 can be relatively fixed. During the use of the product, external water vapor cannot enter the interior of the chassis through the installation gap between the product and the panel 70, thereby achieving a waterproof effect.

[0035] The design focus of the utility model is that a first sealing ring portion and a second sealing ring portion are formed on the waterproof ring, the first sealing ring portion is closely fitted with the front inner wall of the mounting hole of the panel, and the second sealing ring portion is closely fitted with the inner peripheral side wall of the mounting hole of the panel, thereby achieving double waterproofing, effectively improving the waterproof effect of the product, fully meeting high-specification usage requirements, and bringing convenience to use.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
