An electrical connector assembly comprising the female connector and the male connector.

Please refer to fig. 3A, fig. 3B and fig. 3C, which show a first, a second and a third perspective views of an electrical connector assembly according to the present invention. As shown in fig. 3A, 3B and 3C, the electrical connector assembly EA includes: the aforementioned high-voltage connector (i.e., female connector 1) and male connector 2. In one embodiment, the male connector 2 includes: a second insulator 20, a Peripheral supporting wing (Peripheral moving wing) 24, N second terminal receiving parts 21, N second guiding parts 221 (shown in fig. 4), a second left positioning unit including a left extension arm 2L1 and a left positioning part 2L2, and a second right positioning unit including a right extension arm 2R1 and a right positioning part 2R 2.

In more detail, N second terminal accommodation members 21 are connected to the front surface of the second insulator 20, and each of the second terminal accommodation members 21 has a front opening. Fig. 4 shows a perspective view of the N second conduction members 221 and a sectional view of the high-voltage connector (i.e., the female connector 1) of the present invention. As will be understood by engineers familiar with the design and fabrication of electrical connectors, the electrical connector assembly EA adopts a Board to wire (Board to wire) design, wherein the male connector 2 is mounted on a PCB Board and the female connector 1 is connected to a plurality of wires. Therefore, the N second connecting pieces 221 are respectively disposed in the N second terminal accommodating pieces 21, and two ends of each second connecting piece 221 are a contact portion and an insertion portion. According to the design of the present invention, the contact portion is located inside the second terminal accommodation member 21, a bending angle is formed between the insertion portion and the contact portion, and the insertion portion penetrates through the bottom surface of the second insulator 20. On the other hand, as shown in fig. 3A, 3B and 3C, the left extension arm 2L1 of the second left positioning unit is connected to the left side surface of the second insulator 20, and the left positioning member 2L2 is connected to the left extension arm 2L 1. Correspondingly, the right extension arm 2R1 is connected to the right side surface of the second insulator 20, and the right positioning member 2R2 is connected to the right extension arm 2R 1.

As shown in fig. 2A, fig. 2B, fig. 3A, fig. 3B, and fig. 3C, when the male connector 2 and the female connector 1 are connected, the N second terminal accommodating parts 21 of the male connector 2 are inserted into the first mating opening (Receiving opening)10P of the female connector 1, so that the N first terminal accommodating parts 11 of the female connector 1 are respectively embedded into the N second terminal accommodating parts 21 of the male connector 2, and the contact portion of the second conductive part 221 is contacted with the terminal portion of the first conductive part 121. At this time, the shielding frame included in the Terminal unit 12 is used to cooperate with the second positioning device 15 to realize Terminal Positioning Assurance (TPA).

Fig. 5A and 5B show the actuation diagram of the shielding frame and the second positioning device 15 cooperating to realize the Terminal Positioning Assurance (TPA). As shown in fig. 2A, fig. 2B, fig. 5A and fig. 5B, when the N first terminal receiving parts 11 of the female connector 1 are respectively inserted into the N second terminal receiving parts 21 of the male connector 2, the second main plate 151 is pressed by the inner wall of the second terminal receiving part 21, so that the second positioning device 15 moves downward, and the abutting block 154 is disengaged from the groove 111. Continuing, downward movement of the second positioning device 15 causes the abutment block 154 to enter the side opening 112, while the engagement block 153 is snapped into the groove 111. At this time, the supporting block 154 of the second left connecting plate 15L supports against the first elastic sheet 12L1 of the second left plate 12L through the side opening 112, and the supporting block 154 of the second right connecting plate 15R supports against the second elastic sheet 12R1 of the second right plate 12R through the side opening 112. Meanwhile, the second positioning block 151B of the second main plate 151 is located in the limiting hole 12T1 of the second upper plate 12T.

In other words, the second docking opening 12P of the shielding frame has at least a stopper 122S, the second upper plate 12T of the shielding frame is provided with at least a limiting hole 12T1, and the inner surface of the second main plate 151 of the second positioning device 15 is provided with at least a second positioning block 151B. With such a design, as long as the second positioning device 15 is pressed down to make the second main plate 151 enter the top opening 113 of the first terminal accommodating member 11, the second positioning block 151B can be correspondingly dropped into the limiting hole 12T1, so as to limit the Terminal Position (TPA) of the shielding frame. It should be understood that at least a stopper 122S is provided at the opening edge of the second docking opening 12P of the shadow frame, and the stopper 122S stops the terminal portion of the first guiding member 121, now a terminal position limit (TPA) for the first guiding member 121.

As shown in fig. 2A, fig. 2B, fig. 3A, fig. 3B, and fig. 3C, when the male Connector 2 and the female Connector 1 are connected, the Peripheral frame (Peripheral frame)13 of the female Connector 1 and the first positioning device 14 and the second left positioning unit and the second right positioning unit of the male Connector 2 cooperate with each other, so as to realize Connector Position Assurance (CPA).

Fig. 6A and 6B show the actuation diagrams of the peripheral frame 13, the first positioning device 14, the second left positioning unit and the second right positioning unit cooperating with each other to realize the Connector Position Assurance (CPA). As shown in fig. 2A, fig. 2B, fig. 4, fig. 6A, and fig. 6B, when the male connector 2 and the female connector 1 are connected, the left positioning member 2L2 enters the left channel 10L and is pushed by the left pushing member 14L2 in the left channel 10L. More specifically, since the head of the left pushing member 14L2 has a thinned design, the head of the left pushing member 14L2 is inserted into the gap between the left positioning member 2L2 and the left side surface of the first insulator 10 during the process of the left positioning member 2L2 entering the left channel 10L. As the left positioning member 2L2 continues to advance in the left channel 10L, the left positioning member 2L2 is pushed by the left pushing member 14L2 in the left channel 10L. At this time, the bottom of the left retainer 2L2 pushed by the left pusher 14L2 is locked by the left anti-rotation protrusion.

As shown in fig. 2A, fig. 2B, fig. 4, fig. 6A, and fig. 6B, when the male connector 2 and the female connector 1 are connected, the right positioning member 2R2 enters the right passage 10R and is pushed by the right pushing member 14R2 in the right passage 10R. More specifically, since the head of the right pushing member 14R2 has a thinned design, the head of the right pushing member 14R2 is inserted into the gap between the right positioning member 2R2 and the right side surface of the first insulator 10 during the process of the right positioning member 2R2 entering the right channel 10R. As the right positioning member 2R2 continues to advance within the right channel 10R, the right positioning member 2R2 is pushed within the right channel 10R by the right pushing member 14R 2. At this time, the bottom of the right retainer 2R2 pushed by the right pusher 14R2 is locked by the right check convex part.

It should be noted that when the male connector 2 and the female connector 1 are released from the combination, as shown in fig. 2A, fig. 2B, fig. 6A and fig. 6B, a force is applied to the pressing and pushing block 140 to move the first positioning device 14 backward, so that the first positioning block 141B of the first main plate 141 falls into the first groove 13T 1. At this time, the left positioning member 2L2 of the male connector 2 is not pushed by the left pushing member 14L2, and the right positioning member 2R2 is not pushed by the right pushing member 14R 2. Then, the right positioning member 2R2 and the left positioning member 2L2 are pressed by force to retract them. Finally, the male connector 2 is moved backward, so that the right positioning member 2R2 and the left positioning member 2L2 are separated from the right passage 10R and the left passage 10L, thereby completing the operation of releasing the combination of the male connector 2 and the female connector 1.

Thus, the above description is provided for the sake of completeness and clarity of a high voltage connector and an electrical connector assembly having the same. It should be emphasized that the above detailed description is specific to possible embodiments of the utility model, but this is not to be taken as limiting the scope of the utility model, and all equivalent implementations or modifications that do not depart from the technical spirit of the utility model are intended to be included within the scope of the utility model.
