[0042] The present invention also improves the middle iron sheet 6, specifically: both sides of the middle iron sheet 6 are bent to form two first locking sheets 61 and second locking sheets 62 that are fitted together up and down, wherein the second locking sheet 62 is bent downward along the outer side of the middle iron sheet 6 to form a first bending portion 620 and then bent outward horizontally to form, the first locking sheet 61 is formed by bending the outer side of the second locking sheet 62 360 degrees and fitting it onto the upper end surface of the second locking sheet 62, the first locking sheet 61 and the second locking sheet 62 have the same shape and size and are parallel to the middle iron sheet 6, and the front end periphery of the first locking sheet 61 and the second locking sheet 62 both have the locking buckle 60, thereby increasing the thickness and strength of the locking buckle 60, thereby increasing the contact area with the buckle portion 111 of the locking arm 11, thereby ensuring a better locking effect and further enhancing the plugging and unplugging force.

[0044] The first locking piece 61 is stamped with a first contact arm 611 protruding upward on the inner side near the middle iron sheet 6, and the second locking piece 62 is stamped with a second contact arm 621 protruding downward on the inner side near the middle iron sheet 6. The first contact arm 611 corresponds to the second contact arm 621 up and down, and respectively presses and contacts the upper grounding terminal (i.e., one of the upper terminals) in the upper terminal module 51 and the lower grounding terminal (i.e., one of the lower terminals) in the lower terminal module 52, so that the middle iron sheet 6 has an excellent grounding and conduction effect, and grounding parts 63 are formed on both sides of the rear end of the middle iron sheet 6, and the grounding parts 63 protrude from the insulator 5 and contact the female metal inner shell 7, so that the female metal inner shell 7 also has an excellent grounding and conduction effect.

[0045] The assembly structure of the female metal inner shell 7 and the insulator 5 is as follows:

[0046] The female end metal inner shell 7 is cylindrical, and the upper and lower inner walls of the female end metal inner shell 7 are stamped with arc-shaped convex strips 71, both ends of the arc-shaped convex strips 71 are integrally connected to the female end metal inner shell 7, and a window 72 is formed on the rear side of the female end metal inner shell 7, and riveting sheets 73 are formed on both sides of the window 72; correspondingly, the upper and lower surfaces of the insulator 5 are provided with limiting grooves 53 adapted to the arc-shaped convex strips 71, and the rear side of the lower end surface of the upper and lower surfaces of the insulator 5 is provided with riveting grooves 54 adapted to the riveting sheets 73, and the arc-shaped convex strips 71 are formed by the female end metal inner shell 7. The female end metal inner shell 7 is fixedly wrapped around the outer surface of the insulator 5 by pressing it from the outside to the inside in the limiting groove 53 for positioning, and the rivet pressing sheet 73 is riveted into the rivet pressing groove 54 for locking, so that the female end metal inner shell 7 is fixedly wrapped around the outer surface of the insulator 5, and the rear side of the lower end surface of the insulator 5 is exposed in the window 72. The above assembly structure is stable, ensuring that the female end metal inner shell 7 is stably wrapped around the outer periphery of the insulator 5, and because both ends of the arc-shaped convex strip 71 are integrally connected to the female end metal inner shell 7, its structural strength is large, so that the arc-shaped convex strip 71 can be pressed from the outside to the inside in the limiting groove 53 for positioning, and its structure is extremely stable.

[0047] The outside of the female metal inner shell 7 is stamped with a plurality of cards 74, and after the cards 74 are formed, the outside of the female metal inner shell 7 is formed with holes 75 corresponding to the cards 74, and the outside of the female metal shielding shell 8 is stamped with a plurality of card holes 84, wherein a portion of the end of the card 74 is placed in the hole 75, and the other portion is pressed into the card hole 84 to be clamped and fixed.

[0048] In order to prevent the card 74 from being separated from the card hole 84 and becoming ineffective due to the collision of foreign objects, the following design is also made:

[0049] When the card hole 84 is stamped outward on the outside of the female metal shielding shell 8, a blocking piece 85 protruding outward is formed, and the blocking piece 85 is flattened to extend outward, so that the size of the blocking piece 85 is larger than the size of the card hole 84, and then covers the outside of the card 74 to prevent foreign objects from contacting the card 74, thereby ensuring that the foreign objects can only collide with the blocking piece 85 at most, and the size of the blocking piece 85 is larger than the size of the card hole 84 and covers the card 74, so that the blocking piece 85 cannot enter the card hole 84 and contact the card 74, thereby effectively preventing the card 74 from accidentally detaching from the card hole 84 and failing, so that the female metal shielding shell 8 is more stably wrapped around the outer periphery of the female metal inner shell 7.

[0050] The female metal inner shell 7 is formed by a steel-copper composite metal plate, so that it has good electrical conductivity and stable rigidity. The female metal inner shell 7 includes a copper shell 701 located inside and a steel shell 702 located on the outer surface of the copper shell 701. The copper shell 701 has good electrical conductivity and contacts the male metal inner shell in the inserted TYPE-C plug 100 to form a better grounding and conduction effect. The steel shell 702 is located on the outer surface of the copper shell 701, which can improve the rigidity and structural strength of the entire female metal inner shell 7. The copper shell 701 has a copper card 741 and a first hole position 751 corresponding to the copper card 741, and the steel shell 702 has a steel card 742 and a second hole position 752 corresponding to the steel card 742; the copper card 741 and the steel card 742 are fitted together to form the card 74, and the first hole position 751 corresponds to the second hole position 752 to form the hole position 75, wherein the steel card 742 is pressed into the card hole 84 to hold and position it, thereby achieving a better locking effect, and the copper card 741 is placed in the second hole position 752 to ensure that the female metal inner shell 7 and the female metal shielding shell 8 form a better assembly effect.

[0051] In summary, when the TYPE-C plug 100 and the TYPE-C socket 500 are plugged into each other, the buckle portion 111 of the locking arm 11 is locked with the lock buckle 60 of the middle iron sheet 6, forming a one-time plug-in lock, enhancing the plug-in force, and also achieving the purpose of enhancing the grounding conduction effect once; and after the anti-slipping plug-in ring 41 of the male metal shielding shell 4 is inserted into the plug-in interval 80, the positioning convex rib 42 on the outer surface of the anti-slipping plug-in ring 41 is pressed from the inside to the outside into the lock groove 811 of the inner wall of the locking piece portion 81 to lock, forming a secondary plug-in lock, further enhancing the plug-in force. The anti-slipping plug ring 41 is subjected to the extrusion force from the outside to the inside of the locking plate 81, which drives the inner wall of the anti-slipping plug ring 41 to squeeze and wrap the outer surface of the female metal inner shell 7, thereby achieving stable assembly, so that the TYPE-C plug 100 and the TYPE-C female socket 500 form a stable plug-in, and can achieve a better grounding and conduction effect; in addition, the TYPE-C plug 100 and the TYPE-C female socket 50 both adopt a double metal shell structure, which is not only structurally stable, but also has a good effect of shielding external signal interference. Furthermore, after the TYPE-C female socket 500 is installed on the circuit board 83, the welding foot 82 of the female metal shielding shell 8 is also inserted into the grounding pad 831 of the circuit board 83 and welded and fixed, so that the entire TYPE-C female socket 500 cover is locked on the circuit board 83, and the female metal shielding shell 8 is also grounded with the circuit board 83, which can further enhance the grounding and conduction effect, and at the same time has a very strong effect of shielding external signal interference, ensuring the quality of communication.
