Electrical connector assembly

With reference to FIG. 3A, FIG. 3B and FIG. 3C, there are shown a first stereo diagram, a second stereo diagram and a third stereo diagram an electrical connector assembly according to the present invention. The present invention simultaneously discloses an electrical connector assembly EA, and the electrical connector assembly EA comprises: a male connector 2 and the foregoing female connector 1 (i.e., high-voltage connector). As FIG. 3A, FIG. 3B and FIG. 3C show, the male connector 2 comprises: a second insulative housing 20, a peripheral mounting flange 24, N numbers of second accommodating members 21, N numbers of second conductive members 221, a second left position limiting unit consisting of a left arm 2L1 and a left position limiting member 2L2, and a second right position limiting unit consisting of a left arm 2R1 and a left position limiting member 2R2.
As described in more detail below, said N numbers of second accommodating members 21 are connected to the second insulative housing 20, and each said second accommodating member 21 has a front opening. FIG. 4 shows a stereo diagram of N numbers of second conductive members 221 and the female connector 1. According to FIG. 3A , FIG. 3B, FIG. 3C, and FIG. 4, it is known that said N numbers of second conductive members 221 are disposed in said N numbers of second accommodating members 21, respectively, wherein each said second conductive member 221 has a second terminal contacting portion positioned in the second accommodating members 21 and a plugging portion protruded out of a bottom surface of the second insulative housing 20. On the other hand, the left arm 2L1 is extended from a left-side surface of the second insulative housing 20, and the left position limiting member 2L2 is connected to the left extension arm 2L1. Moreover, the right arm 2R1 is extended from a right-side surface of the second insulative housing 20, and the right position limiting member 2R2 is connected to the right extension arm 2R1.
Please simultaneously refer to FIG. 2A, FIG. 2B, FIG. 3A, FIG. 3B, and FIG. 3C. After the male connector 2 is connected to the female connector 1, said N numbers of second accommodating members 21 are received in the receiving opening 10P of the female connector 1, and said N numbers of first accommodating members 11 of the female connector 1 are inserted into said N numbers of second accommodating members 21 of the male connector 2, respectively. Therefore, each said first terminal contacting portion contacts with each said second terminal contacting portion contacts, such that each said first conductive member 121 is electrically connected to each said second conductive member 221. In such case, each said shielding frame cooperates with each said second position limiting devices 15 so as to apply a terminal position assurance TPA to each said terminal unit 12.
FIG. 5A and FIG. 5B show kinematic diagrams of a shielding frame and a second position limiting device in case of achieving terminal position assurance (TPA). As FIG. 2A, FIG. 2B, FIG. 5A, and FIG. 5B show, when said N numbers of second accommodating members 21 are received in the receiving opening 10P of the female connector 1, each said second main plate 151 is pressed down by the inner wall of one said second accommodating members 21, such that each said second position limiting devices 15 moves downward. Then, the embedding block 153 of said second right connection plate 15R and the embedding block 153 of said second left connection plate 15L are released from two said grooves 111, and then downward move so as to get into two said side opening 112 of said first accommodating member 11. As a result, the first elastic member 12L1 of said second left plate 12L is propped by the embedding block 153 of said second left connection plate 15L, the second elastic member 12R1 of said second right plate 12R is propped by the embedding block 153 of said second right connection plate 15L, and the second position limiting block 151B of said second main plate 151 falls into the position limiting opening 12T1 of said second top plate 12T.
According to the present invention, there is a stopping member 122S disposed at an edge of the second receiving opening 12P, the second top plate 12T is provided with at least one position limiting opening 12T1 thereon, and the second main plate 151 has at least one second position limiting block 151B on a bottom surface thereof. By such arrangements, after pressing down the second position limiting device 15 so as to make the second main plate 151 move into the top opening 113 of the first accommodating members 11, the second position limiting block 151B of the second main plate 151 therefore falls into the position limiting opening 12T1 of the second top plate 12T, thereby achieving a first type of terminal position assurance TPA. Moreover, the stopping member 122S props against the first conductive member 121 so as to achieve a second type of terminal position assurance (TPA).
As FIG. 2A, FIG. 2B, FIG. 3A, FIG. 3B, and FIG. 3C show, after the male connector 1 is connected to the female connector 1, the peripheral frame 13, the first position limiting device 14, the second left position limiting unit consisting of a left arm 2L1 and a left position limiting member 2L2, and the second right position limiting unit consisting of a left arm 2R1 and a left position limiting member 2R2 cooperate with each other so as to apply a connector position assurance to the first insulative housing 10 and the second insulative housing 20.
FIG. 6A and FIG. 6B show kinematic diagrams of the peripheral frame, the first position limiting device, the second left position limiting unit, and the second right position limiting unit in case of achieving connector position assurance (CPA). As FIG. 2A, FIG. 2B, FIG. 4, FIG. 6A, and FIG. 6B show, after the male connector 2 is connected to the female connector 1, the left position limiting member 2L2 is stayed in the left channel 10L so as to be propped by the left propping member 14L2. As described in moredetail below, the left propping member 14L2 has a skived slant portion. Therefore, when the left propping member 14L2 moves in the left channel 10L, the skived slant portion would eventually be embedded into the gap between the left-side surface of the first insulative housing 10 and the left position limiting member 2L2. Consequently, with the left position limiting member 2L2 contiguously moving along the left channel 10L, the left position limiting member 2L2 is propped by the left propping member 14L2. In such case, a bottom of the left position limiting member 2L2 is engaged by a left return stop portion that is formed between a front side of the first left plate 13L and the long left opening 13L1, thereby the left position limiting member 2L2 is prevented from returning.
As FIG. 2A, FIG. 2B, FIG. 4, FIG. 6A, and FIG. 6B show, after the male connector 2 is connected to the female connector 1, the right position limiting member 2R2 is stayed in the right channel 10R so as to be propped by the right propping member 14R2. As described in more detail below, the right propping member 14R2 has a skived slant portion. Therefore, when the right propping member 14R2 moves in the right channel 10R, the skived slant portion would eventually be embedded into the gap between the right-side surface of the first insulative housing 10 and the right position limiting member 2R2. Consequently, with the right position limiting member 2R2 contiguously moving along the right channel 10R, the right position limiting member 2R2 is propped by the right propping member 14R2. In such case, a bottom of the right position limiting member 2R2 is engaged by a right return stop portion that is formed between a front side of the first right plate 13R and the long right opening 13R1, thereby the right position limiting member 2R2 is prevented from returning.
It is worth further explaining that, it is able to release the male connector 2 from the female connector 1. As FIG. 2A, FIG. 2B, FIG. 6A, and FIG. 6B show, after firstly applying a force to a pressing block 140 so as to make the first position limiting device 14 move backward, the first position limiting block 141B of the first main plate 141 falls into the first recess 13T1. In such case, the left position limiting member 2L2 is released from the propping of the left propping member 14L2, and the right position limiting member 2R2 is simultaneously released from the propping of the right propping member 14R2. Subsequently, in case the right position limiting member 2R2 and the left position limiting member 2L2 are clamped, it is allowed to move the male connector 2 backward so as to make the right position limiting member 2R2 and the left position limiting member 2L2 leave the right channel 10R and the left channel 10L, respectively. As a result, the male connector 2 is released from the connection of the female connector 1.
Therefore, through the above descriptions, all embodiments of the high-voltage connector according to the present invention have been introduced completely and clearly. Moreover, the above description is made on embodiments of the present invention. However, the embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or alterations within the spirit of the present invention still fall within the scope of the present invention.
