The first set of conductive terminals 3 includes ten conductive terminals 3 arranged in a row, each of the conductive terminals 3 has a pair of joints 31, a soldering portion 32, a fixing portion 33 and a base portion 34. Specifically, the base portion 34 is substantially vertically extending in a strip shape corresponding to the first group of channels 1194 received on the rear wall 119 of the insulating base 11. The abutting portion 31 is below the base portion 34 The position extends forwardly to correspond to the first set of terminal slots 1174 received in the bottom wall 117 of the insulating base 11 and extends upwardly to the bottom side of the mating cavity 19.

Similarly, the second set of conductive terminals 4 includes ten conductive terminals 4 arranged in a row, each of the conductive terminals 4 having a pair of joints 41, a soldering portion 42, a fixing portion 43, and a base portion 44, specifically, the The base portion 44 has a substantially vertical strip shape and is corresponding to the second group of channels 1195 received on the rear wall 119 of the insulating base 11. The abutting portion 41 extends forwardly from the upper portion of the base portion 44, and is correspondingly received in the terminal slot 1185 of the top wall 118 of the insulating base 11 and extends downwardly to the top side of the mating cavity 19. . The fixing portion 43 extends forward from the lower portion of the base portion 44 and is correspondingly received in a second group of fixing grooves 1197 on the rear wall 119 of the insulating base 11; the welded portion 42 is formed by the base portion The bottom of the 44 extends rearwardly and the corresponding surface is soldered to the circuit board 30 (please refer to FIG. 2 in combination). The first group of conductive terminals 3 and the second group of conductive terminals 4 are alternately fixed on the insulating base 11; and since the fixing portion 33 of the first group of conductive terminals 3 and the fixing portion 43 of the second group of conductive terminals 4 are Two different levels of height, preferably the projections of the fixing portion 33 and the fixing portion 43 in the vertical direction do not coincide at all, so that the first group of fixing grooves 1196 and the second group of fixing grooves 1197 are along the electrical connector socket 10 The docking direction is opened on the insulating base 11 at a staggered interval, which is advantageous for compact use of the insulating base 11 The space and the structural strength of the insulating base 11 are maintained.

The outer shape of each of the grounding terminals 5 substantially coincides with the second set of conductive terminals 4, and also has a pair of joints 51, a welded portion 52, a fixed portion 53, and a base portion 54.

Referring to FIG. 4, the abutting portion 31 of the first group of conductive terminals 3 and the abutting portion 41 of the second group of conductive terminals 4 are symmetrically disposed 180 degrees in the mating cavity 19 (or the butting portion 31 is opposite to the butting portion 41). A center point C projected on the front side of the docking chamber 19 is symmetrically disposed at 180 degrees, and is disposed on the lower side and the upper side of the mating chamber 19 in a staggered manner (or a dog-tooth shape). In the preferred embodiment, if a predetermined interval P is defined between two adjacent butting portions 31, 41 of each set of conductive terminals 3, 4, adjacent ones of the two sets of conductive terminals 31 The level interval between the butt portion 41 is preferably half of the set interval (i.e., P/2).

In this embodiment, the serial numbers of the mating portions 31 of the first group of conductive terminals 3 are sequentially increased from left to right, that is, the leftmost one is the S1 terminal, and the second from the left is the S2 terminal, from the left. The number until the rightmost one is the terminal No. S10; the serial number of the butting portion 41 of the second group of conductive terminals 4 is sequentially increased from right to left, that is, the rightmost one is the S1 terminal, and the rightmost number is the second. For the S2 terminal, one from the right to the leftmost is the S10 terminal. The first group of conductive terminals 3 and the second group of conductive terminals 4 The shape and structure of the conductive terminals having the same serial number are completely identical to the electrical definitions, so that the insertion of the electrical connector plug 20 in two postures can achieve the purpose of correctly connecting the corresponding conductive terminals. It should be noted that, in the present design, "180 degree symmetry" means that the shape structure, the spacing and the electrical definition of the abutting portion 31 of the first group of conductive terminals 3 and the abutting portion 41 of the second group of conductive terminals 4 are opposite to each other. The center point C of the cavity 19 is 180 degrees symmetric (or point symmetric with respect to the center point C), in other words, if the butting portion 31 of the S1 terminal of the first group of conductive terminals 3 is around the center point C, etc. Rotating 180 degrees from the ground will completely occupy the position occupied by the abutting portion 41 of the S1 terminal of the second group of conductive terminals 4; the other conductive terminals such as the S2 terminal and the S3 terminal have the same Rotational symmetry relationship.

(The projections of the docking portions in this embodiment are completely non-overlapping, while in other embodiments the projections of the docking portions may also be partially overlapped). For example, from the projection of the two in the horizontal plane, there is one abutting portion 41 between each of the two abutting portions 31, and the abutting portion 41 is located substantially at the center of the two abutting portions 31. By this staggered arrangement, the conductive terminal 2 can be processed into a flat sheet shape (or a blade shape) without bending in a horizontal lateral direction, thereby simplifying the processing difficulty of the conductive terminal 2.
