The housing 11 includes a front opening 111 and a rear opening 112.
The insulating base 12 is disposed in the housing 11 and includes a base 13 and a tongue piece 14; the base 13 is fixed near the rear opening 112 of the housing 11, and the tongue 14 integrally extends from a front side 131 of the base 13 toward the front opening 111, and includes a front side 140, two upper and lower opposite first and second surfaces 141 and 142, and two left and right opposite outer sides 143. In one embodiment, the two outer sides 143 of the tongue 14 are respectively recessed with a slot 144 near the front side 140; the tongue piece 14 may be further embedded into a metal middle partition 15, and a front end 151 of the metal middle partition 15 is exposed from the front side 140 of the tongue piece 14, and a part of the outer side 152 corresponding to the two clamping grooves 144 is also exposed; thus, when other small-sized male electrical connectors (not shown) are inserted by mistake, the exposed portion of the metal intermediate plate 15 can be blocked to avoid damaging the tongue 14.
Each of the charging terminal sets 20 includes a positive terminal 21 and two negative terminals 22; the positive electrode terminal 21 and the two negative electrode terminals 22 of one charging terminal set 20 are respectively disposed in the base 13 and extend forward to the first surface 141 of the tongue piece 14, and as shown in fig. 2, the positive electrode terminal 21 and the two negative electrode terminals 22 of the other charging terminal set 20 are respectively disposed in the base 13 and extend forward to the second surface 142 of the tongue piece 14, wherein as shown in fig. 1B, the two negative electrode terminals 22 of each charging terminal set 20 are respectively located at two sides of the positive electrode terminal 21, or the first spacing d1 is respectively located at two sides of the positive electrode terminal 21. In one embodiment, a front end 221 of each negative terminal 22 is closer to the front side 140 of the tongue 14 than a front end 211 of the positive terminal 21. In addition, in order to improve the charging safety, as shown in fig. 1B, each of the positive terminals 21 of the present utility model is wider than each of the negative terminals 22. In another embodiment, as shown in fig. 1C, each of the positive electrode terminals 21 'and each of the two negative electrode terminals 22' may be formed by a plurality of sub-terminals 200 side by side, and the sub-terminals 200 may be formed by side at a third interval; in addition, in order to correspond to the wider positive electrode terminal 21 shown in fig. 1B, the number of sub-terminals 200 of the positive electrode terminal 21 'in fig. 1C is larger than the number of sub-terminals 200 of each negative electrode terminal 22'.
In addition, the female electrical connector 10 may further comprise at least one signal terminal 23; preferably, as shown in fig. 2, the female connector 10 may include two signal terminals 23, wherein the two signal terminals 23 are respectively disposed in the base 13 and extend forward to the first surface 141 and the second surface 142 of the tongue 14; as shown in fig. 1C, each of the signal terminals 23 is disposed between one of the two negative terminals 22 and the positive terminal 21, or each of the signal terminals 23 may be disposed between one of the two negative terminals 22 and the positive terminal 21, which are disposed on the same surface, at a second interval d 2; in one embodiment, the third distance d3 is greater than the second distance d2. Preferably, as shown in fig. 1B, a front end 231 of the signal terminal 23 is farther from the front side 140 of the tongue piece 14 than the front end 211 of the positive terminal 21.
As shown in fig. 6A to 6C, in another embodiment of the female connector 10, the metal middle partition 15 is exposed outside the front end 151a of the tongue 14, and may further extend toward the front opening 111, and the maximum thickness T2 of the front end 151a of the metal middle partition 15 is greater than the thickness T1 of the portion of the metal middle partition 15 embedded in the tongue 14, but not greater than the thickness T3 of the tongue 14, i.e. the front end 151a does not protrude from the first and second surfaces 141 and 142 of the tongue 14. In the present embodiment, the front end 151a of the metal middle partition 15 can be bent to form a hook shape, but the shape of the front end 151a is not limited to the hook shape; in another embodiment, as shown in fig. 7A and 7B, the front end 151B of the metal middle partition 15 may further extend upward and downward alternately to form a plurality of convex hulls 153, so that the front end 151B is wavy, but the shape of the front end 151B is not limited to wavy; the distance between the convex hulls 153 extending up and down is the maximum thickness of the front end 151b of the present embodiment and is not greater than the thickness T3 of the tongue 14, i.e. the convex hulls 153 extending up do not protrude from the first surface 141 of the tongue 14, and the convex hulls 153 extending down do not protrude from the second surface 142 of the tongue 14. Thus, since the front ends 151a, 151b of the metal middle spacer extend forward and the distance D1 between the front ends 151a, 151b and the housing 11 is reduced due to the maximum thickness, when other small-sized male electrical connectors (not shown) are erroneously inserted, the metal housing will not contact the charging terminal set 20 located on the first surface 141 and the second surface 142 of the tongue piece 14.
Referring to fig. 1A, 3 and 4A, the male charging connector 30 of the present utility model includes a housing 31, an insulating base 32 and at least one charging terminal set 40, and two charging terminal sets 40 are described below.
The housing 31 includes a front opening 311 and a rear opening 312.
The insulating base 32 is disposed in the housing 31 and includes a first fixing base 33 and a second fixing base 34; the first fixing base 33 is fixed near the rear opening 312 of the housing 31, and the second fixing base 34 extends from a front side 331 of the first fixing base 33 toward the front opening 311, and forms a slot 340, and the slot 340 matches with the tongue 14 of the female connector 10.

Each of the charging terminal sets 40 includes a positive electrode elastic terminal 41 and two negative electrode elastic terminals 42; the positive elastic terminal 41 corresponds to the positive terminal 21 of one of the charging terminal sets 20 of the female-end electrical connector 10, and the two negative elastic terminals 42 correspond to the two negative terminals 22 of the charging terminal set 20.

In addition, in order to improve the charging safety, as shown in fig. 1B, each of the positive electrode elastic terminals 41 of the present utility model is wider than each of the negative electrode elastic terminals 42, and as shown in fig. 4A, each of the positive electrode elastic terminals 41 and the two negative electrode elastic terminals 42 is formed in a bending manner so as to maintain a uniform thickness. In another embodiment, as shown in fig. 1C, each of the positive elastic terminals 41 'and each of the two negative elastic terminals 42' may be formed by a plurality of sub-terminals 400 side by side, and the sub-terminals 400 may be formed by side at a third interval d 3; in addition, in order to correspond to the wider positive electrode elastic terminal 41 shown in fig. 1B, the number of sub-terminals 400 of the positive electrode elastic terminal 41 'in fig. 1C is larger than the number of sub-terminals 400 of each negative electrode elastic terminal 42', so that each sub-terminal 400 may be formed by punching and blanking or may be square by bending as shown in fig. 4B.
In addition, the male electrical connector 30 may further include at least one signal terminal 43 corresponding to the signal terminal 23 of the female electrical connector 10; preferably, the male electrical connector 30 may include four signal terminals 43. Specifically, two of the four signal terminals 43 extend forward into the slot 340 along the first inner surface 341 of the second fixing base 34, and the other two signal terminals 43 extend forward into the slot 340 along the second inner surface 342 of the second fixing base 34; thus, when the male electrical connector 30 is inserted into the female electrical connector 10 in both the forward and reverse directions, any one of the signal terminals 43 can be contacted with the signal terminal 23 of the female electrical connector 10. As shown in fig. 1B and 3, each of the signal terminals 43 is disposed between the two negative elastic terminals 42 and the positive elastic terminal 41 on the same surface, and each of the signal terminals 43 may be disposed between the two negative elastic terminals 42 and the positive elastic terminal 41 on the same surface at a second interval d 2; in one embodiment, the third distance d3 is greater than the second distance d2.

Furthermore, since the front ends 211 and 221 of the positive and negative terminals 21 and 22 of the female electrical connector 10 are not flush, and the negative terminals 22 are close to the front opening 111 of the housing 11, the negative elastic terminals 42 of the male electrical connector will contact the corresponding negative terminals 22 first, and then the positive elastic terminals 41 of the male electrical connector 30 will contact the corresponding positive terminals 21 of the female electrical connector 10, and the signal terminals 43 of the male electrical connector 30 will contact the signal terminals 23 of the female electrical connector 10; the design of the contact of the positive electrode terminal, the negative electrode terminal and the signal terminal (for plug detection) can be used for plug safety detection by adopting a device of the female end electric connector, so that the safety power supply of the high-power supply is determined.
