The base 211 and the tail 214 are connected to the middle plate 23 through the terminal group 22. The top surface of the tail 214 is concave downward and protrudes upward on both sides to form a limiting protrusion 216.

[0035] Please continue reading Figure 2 、 Figure 6 As shown, the metal inner shell 30 includes a drawer shell 31, a spliced ​​shell 32 sleeved inside the front end of the drawer shell 31, and a retaining ring 33 installed inside the rear end of the drawer shell 31. The drawer shell 31 is formed by drawing a metal sheet to ensure that its inner wall surface is seamless. The drawer shell 31 includes a rear shell 311, a front shell 312 extending forward from the rear shell 311, and a bent wing 313 formed by folding outward from the front end of the front shell 312. The inner diameter of the front shell 312 is larger than that of the rear shell 311, and a bent step portion (not numbered) is formed between the front shell 312 and the rear shell 311. The spliced ​​shell 32 is made of metal plates that are stamped and riveted. It is inserted into the front shell 312 from the front and fits against the inner wall of the front shell 312. The spliced ​​shell 32 is fixed to the front shell 312 by spot welding on the surface of the front shell 312. The rear end edge of the spliced ​​shell 32 is abutted against the upper limit of the step portion at the rear end of the front shell 312, and the front end of the spliced ​​shell 32 extends beyond the front of the bent wing 313, and a sealing ring groove (unnumbered) for installing or forming the sealing ring 34 is formed in front of the outer shell of the spliced ​​shell 32 and the bent wing 313.

[0036] The retaining ring 33 includes a fitting ring body 331 fitted on the inner wall surface of the rear shell 311 and a blocking ring body 332 formed by folding inward from the front end of the fitting ring body 331. The fitting ring body 331 is fixed to the inner wall surface of the rear shell 311 by spot welding. The blocking ring body 332 is perpendicular to the fitting ring body 331, and the inner diameter of the blocking ring body 332 is smaller than the inner diameter of the fitting ring body 331. The connector 20 is inserted into the metal inner shell 30 from the back to the front. The docking tongue 213 and the extension 212 pass forward through the blocking ring body 332. The front end surface of the base 211 is limited to the rear side of the blocking ring body 332.

[0037] Please continue reading Figures 2 to 4 As shown, the metal shell 40 includes a first shell 41 attached to the upper side of the metal inner shell 30 and a second shell 42 attached to the lower side of the metal inner shell 30. The first shell 41 and the second shell 42 are spot-welded to the metal inner shell 30 respectively and are welded to each other.

[0038] The first outer shell 41 includes a first fitting body 411, first bent portions 412 extending from the lateral sides of the first fitting body 411 along the outer shape of the metal inner shell 30, first ears 413 extending horizontally from the ends of the first bent portions 412, and a cover 414 extending rearward from the first bent portions 412. The first ears 413 include through-holes 4131 extending through the first ears 413 and auxiliary support arms 4132 extending upward from the rear ends of the first ears 413. The covering body 414 includes a connecting plane 4141 extending backward from the outer side of the first bending portion 412, a side covering plate 4142 extending downward from the lateral outer side of the connecting plane 4141, a first welding foot 4143 extending downward from the side covering plate 4142, a rear covering plate 4144 extending downward from the rear side of the connecting plane 4141, and a glue injection gap 4145 formed by cutting out the part between the connecting plane 4141, the rear covering plate 4144 and the first fitting body 411.

[0039] The second outer shell 42 includes a second fitting body 421, second bent portions 422 extending from the second fitting body 421 along the outer shape of the metal inner shell 30, and a second ear portion 423 extending horizontally from the end of the second bent portion 422. The second ear portion 423 includes a first stacking plate 4231 extending horizontally from the end of the second bent portion 422, a second stacking plate 4232 extending from the front end of the first stacking plate 4231 and bent in the opposite direction to fit above the first stacking plate 4231, a first fixing hole 4233 and a second fixing hole 4234 respectively extending through the first stacking plate 4231 and the second stacking plate 4232, a third welding leg 4235 extending downwardly from the rear end of the first stacking plate 4231, and a support arm 4236 extending upwardly from the rear end of the second stacking plate 4232. The support arm 4236 includes a vertical support portion 4237 that extends upward by bending from the rear end of the second stacking sheet 4232, and an elastic end portion 4238 that extends in the opposite direction by bending from the top end of the vertical support portion 4237. A reinforcing rib 4239 is stamped at the bend between the second stacking sheet 4232 and the vertical support portion 4237. A second weld leg 424 is also formed on the inside of the support arm 4236 by extending from the first stacking sheet 4231. This second weld leg 424 mates with the first weld leg 4143 of the first housing 41 to form a single weld leg.

[0040] The first outer shell 41 and the second outer shell 42 are respectively attached to the upper and lower sides of the metal inner shell 30 and spot welded together. Specifically, the first attaching body 411 and the second attaching body 421 are respectively attached to the upper and lower surfaces of the extraction shell 31 and welded together. The first ear 413 and the second ear 423 are attached together and welded together. The first ear 413 and the second stacking sheet 4232 are attached together and welded together. The first stacking sheet 4231 and the second stacking sheet 4232 are attached together and welded together. At this time, the auxiliary support arm 4132 abuts against the front side of the elastic end 4238 of the support arm 4236 to provide better elastic force for the support arm 4236.

[0041] Key References Figure 4 As shown, the inner diameters of the first fixing hole 4233 of the first stacked sheet 4231, the through hole 4131 of the first ear 413, and the second fixing hole 4234 of the second stacked sheet 4232 increase successively, that is, the inner diameter of the first fixing hole 4233 is smaller than the inner diameter of the through hole 4131, and the inner diameter of the through hole 4131 is smaller than the inner diameter of the second fixing hole 4234.

[0042] In another embodiment, the second ear portion 423 may be provided with only the first stacking sheet 4231, without the second stacking sheet 4232. In this case, the support arm 4236 can be formed by bending directly at the rear end of the second ear portion 423 (first stacking sheet 4231). However, the provision of the first and second stacking sheets 4231 and 4232 helps to enhance the strength of the second ear portion 423 when the metal sheet is thinned. Similarly, the second stacking sheet 4232 may be provided on the first ear portion 413, that is, by bending backward from the front end of the first ear portion 413 to form the second stacking sheet 4232 located below the first ear portion 413. The first ear portion 413 and the second ear portion 423 together constitute the ear portion.

[0043] Please refer to Figure 5 As shown, when the USB socket is installed in an electronic device, the rear end of the vertical support portion 4237 of the support arm 4236 abuts against a support object 50 within the electronic device, and the support object 50 applies pressure to the USB socket, causing the sealing ring 34 at the front end of the USB socket to tightly press against the frame of the electronic device to achieve a seal. The auxiliary support arm 4132 provides stronger elastic force for the support arm 4236 to prevent insufficient elasticity of the support arm 4236, which would result in insufficient pressure on the sealing ring 34 and cause a poor seal.

[0044] At the same time, the USB socket is mounted on the printed circuit board 10 and then locked to the frame 70 of the electronic device. Specifically, the printed circuit board 10 is provided with a locking hole 11, which corresponds to the first fixing hole 4233, the second fixing hole 4234, and the through-hole 4131 of the ear. A screw 60 is then inserted through the locking hole 11 of the printed circuit board 10, passes through the first fixing hole 4233, the second fixing hole 4234, and the through-hole 4131, and then locked into the corresponding screw hole in the frame 70. Due to tolerance issues during the manufacturing process, to ensure smooth insertion of the screw 60, the inner diameter of the first fixing hole 4233, which is initially passed through, must be smaller than that of the second fixing hole 4234 and the through-hole 4131 that follow. This prevents the screw 60 from being blocked by the second fixing hole 4234 and the through-hole 4131 due to tolerances.

[0045] Example 2

[0046] Please continue reading Figures 7 to 9As shown, compared to Example 1, Example 2 differs in that the second ear portion 423 of the second housing 42 of the metal housing 40 is no longer folded to form a stacked sheet. That is, the first ear portion 413 and the second ear portion 423 are directly welded together. The support arm 4236 includes a vertical support portion 4237 that is bent upward and extended from the rear end of the second ear portion 423, and support legs 4240 that are bent backward and extended from the lateral sides of the vertical support portion 4237. The support legs 4240 support the surface of the first ear portion 413 to provide auxiliary support force to enhance the rigidity of the support arm 4236.

[0047] In the second embodiment, the inner diameter of the through-hole 4131 of the first ear portion 413 is smaller than the inner diameter of the first fixing hole 4233 of the second ear portion 423. The difference is that in this embodiment, when the USB socket is fixed with the screw 60, the screw passes downward from the first ear portion 413 through the through-hole 4131 and the first fixing hole 4233, and then is locked with the frame 70 of the electronic device.

[0048] The USB socket of the present application is used in an electronic device, which includes a frame, and the frame 70 is horizontally provided with a through hole (not shown). When the USB socket is fixed to the frame 70 by screws 60, the sealing ring 34 at the front end of the USB socket is squeezed on the surface of the frame around the through hole to achieve sealing, and the support arm 4236 abuts against the abutment 50 inside the electronic device to apply an extrusion force to the sealing ring 34 toward the frame 70 to achieve good sealing performance.

[0049] The USB socket and electronic device of this application utilize auxiliary support arms 4132 or support feet 4240 to enhance the rigidity of support arm 4236, preventing the forward compressive force applied to the USB socket from weakening due to a decrease in compressive force and resulting in a poor seal. Furthermore, the inner diameter of the first fixing hole 4233 in the second ear portion 423 is smaller than the inner diameters of the second fixing hole 4234 and through-hole 4131, allowing for smooth insertion of the screw 60 without the risk of insertion failure due to manufacturing tolerances. Furthermore, the first ear portion 413 and the second ear portion 423 are bent and stacked to form a stacking layer, further enhancing the strength of the ears 413 and 423.

[0050] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
