Description

Technical Field

[0001] The utility model relates to the field of electrical connection, in particular to an electrical connector. Background Art

[0002] The Type-C USB electrical connector is a component widely used in various digital products and electronic products at present. It usually includes an insulating plastic body, a terminal module and a metal shell. The terminal module is usually wrapped in the insulating body. In order to achieve good signal transmission quality, a metal isolation plate is also provided in the terminal module of the existing Type-C USB electrical connector. The metal isolation plate is clamped between the upper and lower rows of terminals to shield interference signals. The metal shell surrounds the periphery of the insulating body to realize assembly and fixation, playing a role of shielding and protection. There is only one locking position on both sides of the existing metal partition, and the distance between the detection PIN and the power PIN is relatively close. When the mating end Type-C plug (Plug) is pulled out, the detection PIN and the power PIN are almost simultaneously disconnected within a short distance, which cannot play a role in protecting the circuit and is likely to cause the phenomenon of electric arc, bringing potential functional hazards.

The grounding terminals 210G in the upper row of terminals 210 and the grounding terminals 220G in the lower row of terminals 220 are arranged in a one-to-one correspondence up and down, and the front ends of the grounding terminals 210G, 220G protrude forward to form a bent end 2100, 2200, and the bent ends 2100, 2200 are both bent towards the metal partition 23. Inside the grounding terminals 210G, 220G, there is a pair of power terminals 211, a detection terminal 212 located inside the power terminals 211, and a plurality of signal terminals 213.

[0019] It is worth mentioning that in a preferred embodiment of the present utility model, the metal partition 23 is provided with a horizontally extending flat plate portion 231 and a mounting arm 232 formed by bending downward from the rear edge of the flat plate portion 231. A plurality of through holes 233 are formed in the flat plate portion 231 for achieving limit fixation with the docking tongue plate 12. And on both side edges of the flat plate portion 231, there are a first protruding portion 234 and a second protruding portion 235 that horizontally protrude outward. The first protruding portion 234 and the second protruding portion 235 are arranged adjacent to each other front and back, and a concave notch 236 is formed therebetween. Both the first protruding portion 234 and the second protruding portion 235 protrude beyond the two side edges of the docking tongue plate 12 for achieving snap-fit with a pair of docking end plugs (Plugs). Preferably, the second protruding portion 235 is located at the rear side of the first protruding portion 234, and the second protruding portion 235 protrudes outward beyond the first protruding portion 234, and the first protruding portion 234 is provided with a guiding inclined surface 237 that is connected to the concave notch 236. Preferably, the distance between the ends of the grounding terminals 210G and 220G and the first protruding portion 234 is less than the distance between the ends of the grounding terminals 210G and 220G and the second protruding portion 235, that is, the ends are closer to the first protruding portion 234, while the second protruding portion 235 is farther away from the ends. Preferably, the ends of the grounding terminals 210G and 220G and the power terminal 211 are buried in the docking tongue plate 12 and are aligned with the first protruding portion 124, and the ends of the detection terminal 212 and the signal terminal 213 are buried in the docking tongue plate 12 and are aligned with the second protruding portion 235.

When the mating end plug (Plug) is pulled out, the latching arm (not shown) of the mating end plug (Plug) is pulled from the second protrusion 235 to the first protrusion 234, and the detection terminal 212 is in critical contact with the mating end plug (Plug). Continuing the pulling-out operation, when the detection terminal 212 breaks contact, the power terminal 211 still remains in contact with the mating end plug (Plug). At this time, the mating end plug (Plug) is stuck at the first protrusion 234. Upon receiving the instruction from the detection terminal 212, the power supply is disconnected. And when the power terminal and the mating end plug (Plug) are pulled out from each other, since there is no power supply, the scraping between the two will not cause an electric arc phenomenon, greatly improving the quality and reliability.

Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, can make many possible changes and modifications to the technical solution of the present utility model by using the method content disclosed above, and all of them fall within the scope protected by the claims.
