Description
Technical Field
[0001] The utility model relates to the technology of the field of electrical connectors, and in particular to a raised Type-C connector. Background Art
[0002] Type-C is a USB interface standard that is smaller than Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). USB Type-C has four pairs of TX / RX breakout lines, two pairs of USB D+ / D-, one SBU pair, two CC lines, four VBUS lines, and four ground lines.
[0003] To increase the height of the interface, a raised Type-C connector is now available on the market. Its main structure includes an insulating body, a terminal group, and a shielding shell. The insulating body includes a base, a tongue plate, and a raised seat. The tongue plate extends forward from the front side of the base, and the raised seat extends downward from the bottom surface of the base. The terminal group is arranged on the insulating body, and the terminal group has multiple contact portions and multiple welding portions. The multiple contact portions are respectively exposed on the upper and lower surfaces of the tongue plate, and the multiple welding portions extend outward from the raised seat. The shielding shell is covered on the outside of the insulating body.
[0004] In the prior art, to enhance the structural strength of the shielded shell of a raised Type-C connector, it typically consists of an inner shell and an outer shell, with the outer shell fitting over the inner shell and secured by welding. However, the outer shell and inner shell are secured solely by welding, resulting in a weak connection. After prolonged plugging and unplugging, the outer shell and inner shell can easily separate, causing the outer shell to retreat relative to the inner shell. Furthermore, the inner shell also suffers from an unstable connection to the base, making it prone to retreating relative to the base, adversely affecting the normal use of the product. Therefore, improvements to the current raised Type-C connector are necessary. Utility Model Content

[0046] Please refer to Figures 1 to 5 , which shows the specific structure of the first preferred embodiment of the present invention, including an insulating body 10 , a terminal group 20 and a shielding shell 30 .
[0047] The insulating body 10 includes a base 11, a tongue plate 12, and a raised seat 13. A limit platform 101 is protruding from the top of the base 11. The tongue plate 12 extends forward from the front side of the base 11. The raised seat 13 extends downward from the bottom surface of the base 11. In this embodiment, the limit platforms 101 are arranged in two separate left and right positions, and a stopper 102 is protruding from the base 11. The stopper 102 is higher than the two limit platforms 101 and connected between the rear ends of the two limit platforms 101. The stopper 102 and the two limit platforms 101 form a limit groove 103. In addition, both sides of the base 11 are provided with outwardly protruding protrusions 104. In addition, a fixing column 105 extends from the bottom of the raised seat 13. The fixing columns 105 are arranged symmetrically on the left and right to be inserted into the fixing holes of the external circuit board for fixed installation.
[0048] The terminal assembly 20 is mounted on the insulating body 10 and has a plurality of contact portions 21 and a plurality of soldering portions 22. The contact portions 21 are exposed on the upper and lower surfaces of the tongue plate 12, while the soldering portions 22 extend outward from the raised base 13. In this embodiment, there are six contact portions 21 and two soldering portions 22. The six soldering portions 22 are spaced side by side and extend horizontally and rearwardly from the bottom of the raised base 13. Furthermore, the terminal assembly 20 has hooks 23 on both sides of its front end, one of which is exposed on either side of the front end of the tongue plate 12.
[0049] The shielding shell 30 includes an inner shell 31 and an outer shell 32. The inner shell 31 covers the base 11 and the tongue plate 12. The inner shell 31 has an inner top plate 311. The outer shell 32 covers the outside of the inner shell 31. The outer shell 32 has an outer top plate 321. The outer top plate 321 is superimposed on the inner top plate 311 and fixed together by laser spot welding. The rear end face of the inner shell 31 abuts against the front side of the limit platform 101. The inner top plate 311 has a limit hole 301. The outer top plate 321 is punched from the outside to the inside to form a limit plate 302. The limit plate 302 extends backward and is inserted from the front to the back into the limit hole 301 to prevent the outer shell 32 from retreating. At the same time, the outer shell 32 is welded to the external circuit board to ensure the grounding function. In this embodiment, the inner shell 31 and the outer shell 32 are both stamped iron shells, which are simple in structure, easy to manufacture, and low in cost. The two limiting holes 301 are symmetrically arranged on the left and right, and the corresponding limiting plates 302 are also symmetrically arranged on the left and right. The two limiting plates 302 are respectively inserted into the two limiting holes 301 to limit the position, thereby better preventing the outer shell 32 from moving backward. In addition, the rear end of the outer top plate 321 is punched from the outside to the inside to form a convex bump 303. The convex bump 303 is inserted into the limiting groove 103 from the front to the back, and the rear end surface of the outer top plate 321 abuts against the front side surface of the stopper 102 to prevent the outer shell 32 from moving backward.
[0050] The outer shell 32 also has outer panels 322 on both sides, positioned on the left and right sides of the raised seat 13. These panels extend forward and backward, with their front ends bent inward to form support panels 323. These panels 323 extend left and right and face each other. They are located in front of the raised seat 13 and rest against the front bottom of the inner shell 31 to prevent it from sagging. Furthermore, support springs 304 are punched inward from the rear sides of the outer panels 322. These support springs 304 rest against the left and right bottoms of the rear end of the inner shell 31 to further prevent it from sagging. The outer shell 32 is also soldered to the external circuit board via the outer shell 32 to ensure grounding. Furthermore, these support springs 304 rest against the front side of the protrusion 104, squeezing both the inner shell 31 and the support springs 304 together through the protrusion 104 to secure the inner shell 31. In addition, external fixing legs 305 extend downward from the front bottom and the rear bottom of the two outer plates 322 to facilitate plugging and mounting with an external circuit board.
[0051] The manufacturing and assembly process of this embodiment is described in detail as follows:
[0052] First, the terminal group 20 is punched out, and then the terminal group 20 is placed in an injection mold to injection mold the insulating body 10, so that the terminal group 20 and the insulating body 10 are inlaid and fixed together, and then the outer shell 32 is fitted and fixed on the inner shell 31 to form the shielding shell 30, and finally, the shielding shell 30 is fitted and fixed on the insulating body 10.
[0053] Please refer to Figures 6 to 10 As shown, it shows the specific structure of the second preferred embodiment of the utility model. The specific structure of this embodiment is basically the same as the specific structure of the first preferred embodiment mentioned above, and the difference is:
[0054] In this embodiment, inner panels 312 extend downward from both sides of the rear end of the inner shell 31. These inner panels 312 overlap the left and right sides of the raised seat 13, respectively. Two outer panels 322 overlap the outer sides of the inner panels 312, respectively. Hooks 106 extend from the rear edge of the raised seat 13. These hooks 106 engage the rear edges of the inner panels 312 to prevent them from expanding outward, ensuring they remain in contact with the sides of the raised seat 13. Furthermore, the rear edges of the outer panels 322 are provided with slots 306, into which the hooks 106 engage, further securing the outer panels 322. In addition, a positioning groove 307 is recessed on the rear edge of the upper end of the inner plate 312, and the protrusion 104 is stuck in the positioning groove 307. In addition, internal fixing feet 308 extend downward from the front and rear sides of the lower end of the inner plate 312 to facilitate plugging and fixing with the external circuit board.
[0055] The manufacturing and assembly process of this embodiment is basically the same as that of the first preferred embodiment described above, and the manufacturing and assembly process of this embodiment will not be described in detail here.
[0056] The design focus of the utility model is: by using the limit platform to limit the inner shell, the inner shell is effectively prevented from retreating relative to the base, and at the same time a limit hole is opened on the inner top plate, and a limit piece is formed by punching from the outside to the inside on the outer top plate.
