In this embodiment, the surface of the tongue 12 is provided with a whole row of covering areas 13 adjacent to the base 11, the thickness of the base 11 is slightly larger than the thickness of the tongue 12, the whole row of covering areas 13 is located between the base 11 and the tongue 12, wherein the whole row of covering areas 13 extends from one side of the tongue 12 to the other side of the tongue 12, that is, the whole row of covering areas 13 is covered on the surface of the inner side of the tongue 12, the surface of the inner side of the tongue 12 forms the whole row of covering areas 13 without the first contact section 24 and without the second contact section 34, and the whole row of covering areas 13 is the contact area of the plug terminal 92 of the non-.

In this embodiment, the plurality of socket terminals 200 include connecting sections (the first connecting section 25 or the second connecting section 35) disposed on the base 11 and the tongue piece 12, and contact sections (the first contact section 24 or the second contact section 34) extending from one side of the connecting sections and located on the upper surface or the lower surface of the tongue piece 12, and each socket terminal 200 includes a relief portion 29, 39 (as shown in fig. 4) located between the contact sections and the connecting sections.

Also, the relief portions 29, 39 are respectively located between the tongue piece 12 and the base 11 (as shown in fig. 8), and the relief portions 29, 39 of each socket terminal 200 are covered with the entire row of covering regions 13 of the tongue piece 12. In this embodiment, the thickness of the base 11 is slightly larger than that of the tongue 12, and one end of each of the relief portions 29 and 39 of each of the socket terminals 200 is located in the base 11.

In this embodiment, the range of the offset portion 29 of the first flat ground terminal 23 and the first flat power terminal 22 is larger than the range of the offset portion 29 of the first flat signal terminal 21, i.e. the width of the position of the offset portion 29 of the first flat ground terminal 23 and the first flat power terminal 22 is larger, the width of the position of the first contact section 24 of the first flat signal terminal 21 is the same as the width of the position of the offset portion 29, and the design of each terminal of the second flat signal terminal 3 is the same.

In this embodiment, when the plurality of plug terminals 92 of the plug electrical connector 9 contact the plurality of receptacle terminals 200 of the receptacle electrical connector 100, the metal phase rubs to generate a plurality of chips 99 to the upper and lower surfaces of the tongue 12 on the relief portions 29, 39 (fig. 11 only shows the upper surface of the tongue 12).

In particular, since the metal scraps 99 are easily accumulated in the region between the tongue piece 12 and the base 11 when the plurality of receptacle terminals 200 and the plurality of plug terminals 92 are in frictional contact, when the thickness of the receptacle terminal 200 at the relief portions 29 and 39 is reduced to form the insulating main body 1, the tongue pieces 12 made of plastic material are covered on the relief portions 29 and 39, and the metal scraps 99 are covered on the entire row of covered regions 13.

When the plug terminal 92 is inserted due to the accumulation of metal debris 99 after the plurality of socket terminals 200 and the plurality of plug terminals 92 are inserted and pulled out, the adjacent plurality of plug terminals 92 have poor withstand voltage, or the plurality of plug terminals 92 are in contact with the plurality of socket terminals 200, the plurality of plug terminals 92 and the plurality of socket terminals 200 due to the metal debris 99 to cause short circuit, that is, the terminals with different properties are conducted to cause short circuit.

The area of the tongue piece 12 made of plastic material covering the plurality of socket terminals 200 is increased (the covering area of the whole row of covering areas 13 is increased), so as to prevent the contact sections (the first contact section 24 or the second contact section 34) of the plurality of socket terminals 200 of the socket electrical connector 100 from being raised and protruding out of the surface of the tongue piece 12 after being processed and baked at high temperature.

The contact section of a plurality of traditional socket terminals is arranged on the area of the whole tongue piece (the coverage area of the whole row of coverage areas is not added), the tongue piece made of plastic is formed on the contact section of the plurality of socket terminals, after the processing procedure is expanded with heat and contracted with cold, tiny terminal slot holes are formed between the plastic and metal, and the terminal slot holes enter conductive sundries or water to cause poor voltage resistance or short circuit contact of the adjacent plurality of socket terminals. In the embodiment, the coverage area of the whole row of coverage areas 13 is increased, so that terminal slots are prevented from being formed in the whole row of coverage areas 13, the problem that the terminal slots enter conductive impurities or water to cause poor voltage resistance or contact short circuit of adjacent socket terminals 200 is avoided, and moreover, the injected plastic is not blocked by the terminal slots during injection molding, so that the mold unsaturation during molding can be effectively improved, and the strength of the socket electric connector 100 product is improved.

In this embodiment, the receptacle electrical connector 100 further includes a fixing block 15 (as shown in fig. 2 and 4), the fixing block 15 is distributed with comb-end holes, when the insulating main body 1 is insert-molded (insert-molding) to combine the receptacle terminals 200 and the fixing block 15, plastic may overflow from the comb-end holes, so that the plastic is quickly spread over the shape of the insulating main body 1, and the molding time is shortened. During injection molding, the entire row of covering areas 13 are not designed with the comb end holes, so that the comb end holes are prevented from blocking the flow of injected plastic, the mold-unsaturation phenomenon during molding can be effectively improved, and the strength of the socket electric connector 100 product is increased.

In this embodiment, each socket terminal 200 is positioned on the fixing block 15 and combined with the insulating main body 1, and here, the 1 st molding process is performed to combine each metal piece 7 with the fixing block 15, then each socket terminal 200 is placed and positioned on the fixing block 15, and then the 2 nd molding process is performed to mold the insulating main body 1 outside each socket terminal 200 and the fixing block 15.

In other words, after the socket electrical connector 100 of Type-C is inserted and pulled out for a long time, the metal scraps 99 of the plural socket terminals 200 and the plural plug terminals 92 in frictional contact are easily accumulated in the inner side area of the surface of the tongue piece 12 of the insulating main body 1, and when accumulated to a certain extent, the metal scraps may occupy the gap between two adjacent socket terminals 200, and cause the adjacent socket terminals 200 to contact, thereby causing poor voltage resistance and even short circuit.

In this embodiment, the plug electrical connector 9 is inserted into the receptacle electrical connector 100 to reach the positioning position, the plurality of contact ends 923 of the plurality of plug terminals 92 are adjacent to the entire row of coverage areas 13 and keep a predetermined distance from the entire row of coverage areas 13, and after the long-term plugging, the metal chippings 99 are pushed to the entire row of coverage areas 13 by the contact ends 923.

Moreover, the metal sheet 7 is arranged on the tongue piece 12, so that the strength and the shielding effect of the tongue piece 12 are improved. That is, the metal sheet 7 is used to improve the problem of crosstalk signal interference by the isolation of the metal sheet 7 when the plurality of first contact sections 24 and the plurality of second contact sections 34 are transmitting signals, and simultaneously, the metal sheet 7 is located on the tongue 12 to improve the structural strength of the tongue 12 itself.

Furthermore, a plurality of partial stoppers 151 may be disposed in each through hole 72.

In this embodiment, each through hole 72 forms an expanding portion 721 extending toward the hook structure 71, so as to increase the space of each through hole 72 and increase the area of the expanding portion 721 formed by plastic. Furthermore, the stoppers 151 are respectively located at the positions of the through holes 72 and the expanding portions 721 (as shown in fig. 5), and the stoppers 151 are clamped at both sides of the front ends of the socket terminals 200.

In addition, the soldering pins 75 penetrate the rear of the base 11 and solder the circuit board, allowing the metal plate 7 to be grounded.

In this embodiment, each metal sheet 7 has a contact arm 711 outside each through hole 72, and the outer side surface of the contact arm 711 forms a fastening concave portion 712, when the plug electrical connector 9 is plugged into the receptacle electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 will fasten the fastening concave portions 712, and when plugging, the hooks 95 contact the contact arm 711, the contact arm 711 moves towards the inside of the through hole 72, and the contact arm 711 forms an elastic swing effect.

In other words, after each metal sheet 7 is disposed in each through hole 72, the hook structure 71 forms a hollow elastic structure, when the plug electrical connector 9 is mated with the receptacle electrical connector 100, the hooks 95 on both sides of the plug electrical connector 9 contact the hook structure 71, and the contact arm 711 of the hook structure 71 swings elastically toward the inside of the through hole 72; the problem of the hook structure 71 being worn by the hooks 95 on both sides of the plug electrical connector 9, which is caused by hard interference of the hooks 95 on both sides of the plug electrical connector 9 when the plug electrical connector 9 is mated with the receptacle electrical connector 100, and the problem of structural damage and bad contact caused by serious wear is avoided.
