The end portion 31 covers the front end surface 241, and the covering portion 32 covers the extending surface 242, thereby extending the insulating portion toward the inside of the receiving space 12, so that the contact portion 23 is not easily contaminated or damaged. The existing front end portion of the terminal is easily touched to affect the stability of the power transmission, and the safety performance of the power connector is improved. In addition, the outer surface 321 of the covering portion 32 is coplanar with the contact surface 231, and the purpose of the setting is to ensure that the socket terminal 7 _ slides on the outer surface 321 and the socket terminal 7 finally contacts the contact surface 231. Stationarity in direction. • Referring to the fifth and eighth figures, the additional grounding terminal 4 is elongated, and is located below the grounding terminal 2 and is housed in the same terminal receiving passage 121 together with the grounding terminal 2. It has a fixed body attached to the plug! The inner fixing portion 4 extends rearward from the fixing portion 41 beyond the plug insulating body! The outer connecting portion 42 and the self-fixing portion 41 extend forwardly to each other. P 43, the abutting portion 43 has a butt end 43〇 that is slightly folded upward. The mating end 43 is located at a corresponding position below the middle of the outer surface 321 of the covering portion 32 of the plug terminal 2, and the positional relationship is such that the additional grounding terminal 4 is connected to the corresponding grounding terminal of the grounding terminal 2 and the socket power connector. After the contact, the grounding terminal 7 is electrically connected to the grounding terminal. That is, the grounding terminal 4 is also a grounding terminal, and the grounding terminal 2 is connected to the grounding terminal 2 to connect the same grounding terminal 7 of the socket power connector 10. Thereby, the additional grounding terminal 4 functions as a backup grounding. When the grounding terminal 2 fails to read the shape, f, _ plus the grounding terminal 4 is grounded, and it is extremely important for the connection of high power and high current. Improve the reliability of the power transmission wheel. Referring to the second, seventh and eighth figures, the socket insulative housing 6 includes a plug-in surface 6 extending inwardly from the central portion of the mating surface 61 and extending through the receiving passage (9) of the socket insulating body 6. The insulating body 6 is provided on the side of the mating surface 61 with a protective block 62 extending along the lower surface of the terminal receiving passage 6 to the inside thereof. In particular, in order to ensure the endurance of the terminal when the power connector 10 and the socket power connector 20 are docked, the bottom of the socket insulative housing 6 is further provided with a latching arm 63 for insulating the plug body. The groove 14 of i is held together. The latching arm 63 includes a latching block 631 and a pressing portion 632 which are spaced apart from each other, the function of which will be described later. The socket terminal 7 includes an elastic contact arm 71 and a connecting portion 74 that is connected to the resilient arm 71 and protrudes beyond the socket insulating body 6. The contact arm 71 includes a raised elastic engagement portion 72 and a free end 73 extending forwardly and downwardly from the mating portion 72. The resilient mating portion 72 provides a certain degree of deformability. When the socket terminal 7 is fixed in the terminal receiving passage 60 as shown in the eighth figure, the elastic fitting portion 72 extends beyond the upper surface of the protection block 62 when the socket power connector 20 is in contact with the power connector 1'. The elastic fitting portion 72 is pressed against the contact surface 231. The free end 73 is lower than the upper surface of the protection block 62, so that the finger can be prevented from touching the contact arm 71, and the foreign object can also be prevented from damaging the contact arm 7. Accordingly, in the present embodiment, the socket terminal 7 is a plurality of socket plugs of the embodiment of the present invention are three 201138235 roots arranged in an isosceles triangle. The socket terminal 7 includes a socket power terminal and a socket ground terminal 'a pair of positive and negative socket power terminals 7 and a socket ground terminal 7 at the vertex. Of course, the terminal receiving passage 60 of the socket terminal 7 is also arranged in an isosceles triangle shape. The protective block 62 located in the terminal receiving passage 60 of the apex of the isosceles triangle has an additional terminal receiving channel 65'. The additional terminal receiving channel 65 is The terminal receiving passages 6 are connected to each other. As shown in FIG. 8 , when the plug power connector 10 and the socket power connector 20 are mated with each other, the socket insulating body 6 is received in the receiving space 丨 2 of the plug insulating body ,, and the protective block 62 can guide the plug. The terminal 2 extends into the terminal receiving passage 60 of the socket power connector 2, and the plug terminal 2 is in electrical contact with the socket terminal 7. During this process, the elastic engaging portion 72 of the contact arm 71 first slides on the outer surface 321 of the covering portion 32, and then the mating portion 72 passes over the outer surface 321 and finally withstands the contact surface 231 of the contact portion 23. . At the same time, the fastening block 631 of the fastening arm 63 protrudes to the plug insulating body! In the groove 14, the strength of the plug W is connected to the H 1G and the socket power connector 2G to prevent looseness. The plug power supply is connected to the H 1〇 additional connecting shaft 4 and the terminal receiving port & and is in contact with the grounding socket terminal 7 of the socket power connector 2G located at the apex of the isosceles triangle, the X contact is generated at the plug ground terminal 2 After pressing against the socket ground terminal 7. When it is necessary to separate the plug power connector 10 and the outlet power connector 2 from each other, the c pressing portion 632 ' is pushed downward to disengage the latching block (8) of the latching arm 63 from the recess 14 of the plug insulating body 1. Of course, in other embodiments, the description of the latching arm 63 can also be placed on the plug-in body body 电源 of the power connection 1G, and the nucleus 14 is placed on the rim body 6 to achieve mutual deduction. purpose. The towel plug terminal 2 and the plug insulating body 1 and the socket terminal 7 and the socket insulating body 6 may be configured to fix the terminal in the insulating body by injection molding 201138235, or assemble the terminal to insulate the body by assembly. Inside. In addition, in the present embodiment, the additional ground terminal 4 is disposed in the plug insulating body 1 of the plug power connector 10. Obviously, for the person skilled in the art, the socket lion connection H 20 _ seat can also be insulated. The structure of the body 6_single changes so that the additional grounding terminal is disposed in the socket insulating body 6. In other words, the power supply connector (plug power connector U) is provided with an additional ground terminal 4 in the plug connector power connector 10 side, and the socket power connector 20 side can also be provided. In addition, the above three specific terminals related to the connector «connecting the _ terminal 2 of the n 1 命名 are named as the power terminal and the ground terminal, and the socket terminal 7 of the socket power connector 20 also has the power terminal and the ground terminal, so the plug plug The power terminal and the grounding terminal of the power connector can also be referred to as a plug power terminal and a ground terminal, respectively.
