The exemplary embodiments of the present invention are described in detail with reference to the accompanying drawings, in which However, the present invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and the inventive concept Fully communicated to those skilled in the art. In the following detailed description, numerous specific details are set forth It is apparent, however, that one or more embodiments may be practiced without the specific details. In other instances, well-known structures and devices are schematically shown to simplify the drawings. According to a general concept of the present invention, a power connector is provided, comprising: an insulative housing having a bottom surface, a top surface and two lateral surfaces; three terminals disposed in an insulating housing in a length direction a locking mechanism fixed to a top surface of the insulative housing and configured to detachably lock the power connector to a mating connector; a handle; and an unlocking mechanism coupled to the handle and The configuration is to unlock the power connector and the mating connector as the handle moves relative to the insulative housing. 1 is an illustrative perspective view of one of the power connectors in accordance with an embodiment of the present invention. One embodiment of the present invention is directed to a power connector, and more particularly to a miniature power connector that is adapted to be centrally disposed in a small space. In the illustrated embodiment, the power connector mainly comprises: an insulative housing 100 having a bottom surface, a top surface and two lateral surfaces; three terminals; a locking mechanism 500; an unlocking mechanism; and a handle 300. In an embodiment, the locking mechanism 500 includes a fixing member 510 mounted on a top surface of the insulative housing 100 and configured to hold the locking mechanism 500 on the insulative housing 100; a locking member 530 configured to be insulated The distal end of the outer casing 100 is configured to be locked with the mating component 210 of the mating connector 200; and a connecting component 520 extending in the longitudinal direction of one of the insulative housings 100 and coupled to the locking component 530 and the stationary component Between 510. The locking member 530 can be locked to the mating component 210 of the mating connector 200 such that the power connector cannot be pulled out of the mating connector 200 at will, thereby ensuring a secure connection between the power connector and the mating connector 200. When it is necessary to disconnect the power connector from the mating connector 200, the handle 300 in the locking mechanism interacts with the unlocking mechanism such that one of the distal ends of the connecting member 520 and the locking member 530 are jacked up. Therefore, the locking member 530 and the mating member 210 are released from each other, and the power connector is allowed to be pulled out from the mating connector 200. 2 and 3 are respectively a cross-sectional view and a partial perspective enlarged view of a vicinity of a mounting member 512 of a power connector according to an embodiment of the present invention. As shown in FIG. 2 and FIG. 3, in an embodiment of the present invention, the fixing member 510 includes a base 513 extending in a width direction of one of the insulating housings 100 and disposed on a top surface of the insulating housing 100. And at least one mounting member 512 extending from at least one end of the base 513 to at least one lateral surface of the insulative housing 100, respectively. Mounting members 512 are respectively coupled to the two lateral surfaces of the insulative housing in a snap fit manner. According to an embodiment of the invention, one of the first recesses 107 extending from the top surface to the two lateral surfaces is formed at a proximal end of the insulative housing 100. The fixing member 510 is fitted into the first recess 107. Each of the mounting members 512 includes a mounting hole 511, and one of the mounting protrusions 101 that can be fitted into the mounting hole 511 is disposed in the first recess 107. Since one of the lengths of the fixing member 510 is set to be substantially equal to one of the widths of the insulative housing 100, the mounting member 512 is pressed against the lateral surface of the insulative housing 100 and/or the fixing member 510 is insulated during the mounting of the locking mechanism 500. The bottom of the first recess 107 of the outer casing 100 is pressed tightly, so that the mounting member 512 is difficult to pass over the mounting protrusion 101. In this case, as shown in FIG. 3, the top surface of the mounting tab 101 is tilted to reduce the forward resistance of the mounting member 512 above the mounting tab 101. The mounting member 512 can be guided to slide across the top surface of the mounting tab, and then the mounting tab 101 is introduced into the mounting hole. In this way, a snap fit between the mounting protrusion 101 and the mounting hole is formed. It is contemplated by those skilled in the art that the snap fit between the mounting member 512 and the mounting tab 101 can be modified, for example, to be formed on the top surface of the insulative housing 100 or on the top surface of the first recess. The snap fit does not depart from the scope of the invention. In an exemplary embodiment, the mounting hole 511 and the mounting protrusion 101 may be formed to be substantially rectangular. In an exemplary embodiment, as shown in FIGS. 1 , 4 , and 5 , the unlocking mechanism includes: an actuating lever 400 that passes under the fixing member 510 and is coupled to the handle 300; and a pivoting frame 600, It is disposed between the connecting member 520 and the insulative housing 100 and is coupled to one of the distal ends of the actuation lever 400. The pivot frame 600 is configured to pivot relative to the insulative housing 100 to lift the attachment portion 520 and the locking portion 530 by pulling the handle 300 and then pulling the actuation lever 400. The pivoting frame 600 includes a horizontal member 610 extending in the width direction, the distal end of the actuating lever 400 being coupled to the horizontal member, and two lateral arms 620 each being insulated from both ends of the horizontal member 610 The two lateral surfaces of the outer casing extend downwardly and are pivotally connected to the two lateral surfaces of the insulative housing 100, respectively. In an exemplary embodiment, as shown in FIGS. 1, 4, and 5, the insulative housing includes a body 110 and an insertion member 120 to be inserted into one of the mating housings of the mating connector, at the insertion member 120. A step is formed at the joint with the body 110; one of the auxiliary actuating members 402 extending obliquely toward the step is provided at a side of the horizontal member 610 opposite the actuating lever 400. In this manner, during pivoting of the pivoting frame 600 relative to the insulative housing 100 by pulling the handle 300 and then pulling the actuating lever 400, the auxiliary actuating member 402 abuts against and slides over the step, such that The connecting portion 520 and the locking portion 530 are lifted by the pivoting frame 600. A second recess 106 is formed in the top surface and in the two lateral surfaces at the distal end of the insulative housing 100, and the pivot frame is mounted in the second recess. A third recess 105 is formed on the top surface of the insulative housing 100 in the length direction, and the actuating lever 400 and the connecting member 520 of the locking mechanism 500 are movably received in the third recess 105.
