According to a general technical concept of the present invention, a power connector is provided, comprising: an insulating housing having a bottom surface, a top surface and two side surfaces; three terminals arranged side by side along the length direction in the insulating housing; a locking mechanism fixed on the exterior of the surface of the insulating housing and configured to detachably lock the power connector and mating connector together; a handle; and an unlocking mechanism connected to the handle connected, and configured to release the locking mechanism for the power connector and the mating connector as the handle moves relative to the insulating housing.

Fig. 1 shows a perspective view of a power connector according to an embodiment of the present invention. In an embodiment of the present invention, a power connector is disclosed, especially a miniature power connector suitable for high-density arrangement in a narrow space. In the illustrated embodiment, the power connector mainly includes an insulating housing 100 , three terminals, a locking mechanism, an unlocking mechanism and a handle 300 .

Wherein, the locking mechanism 500 includes: a fixing part 510 installed on the outside of the surface of the insulating housing 100 to install the locking mechanism 500 on the insulating housing 100; a locking part 530 on the The outer part of the distal end of the insulating housing 100 to lock with the mating portion 210 of the mating connector 200; and a connecting portion 520 extending in the lengthwise direction of the insulating housing 100 and connected to the locking between the part 530 and the fixed part 510. The fixing portion 510 includes: a base portion 513 extending in the width direction of the insulating housing 100 and disposed on the top surface of the insulating housing 100 ; and at least one mounting portion 512 extending from the base portion 513 The ends extend to the sides of the insulating housing 100 .

The locking part 530 can be locked on the mating part 210 of the mating connector 200, so that the power connector cannot be pulled out from the mating connector 200 arbitrarily, thereby ensuring the connection between the power connector and the mating connector 200 of firmness. When the power connector needs to be disconnected from the mating connector 200, the handle 300 in the locking mechanism interacts with the unlocking mechanism, so that the distal end of the connecting part 520 and the locking part 530 are pushed up, thereby locking The part 530 and the mating part 210 are unlocked, and the power connector is pulled out from the mating connector 200 .

Fig. 2 and Fig. 3 are respectively the sectional view and partial perspective view near the mounting part 512 of the power connector according to one embodiment of the present invention; As shown in Fig. 2 and Fig. 3, in one embodiment of the present invention, the fixed The part 510 includes: a base part 513 extending in the width direction of the insulating case and provided on the top surface of the insulating case; and at least one mounting part 512 extending from the end of the base part 513 to the on the side of the insulating case.

Since the length dimension of the fixing part 510 is set to be the same as the width dimension of the insulating housing 100, during the installation of the locking mechanism 500, the mounting part 512 is tightly attached to the surface of the insulating housing 100, or tightly against the surface of the insulating housing 100. The bottom of the first groove 107 of the insulating housing 100 makes it difficult for the installation part 512 to pass over the top of the installation protrusion 101. In this case, making the top surface of the installation protrusion 101 an inclined slope can make the installation part 512 under the installation protrusion 101. The upward and forward resistance is reduced, and the installation part 512 can be guided to slide over the top of the installation protrusion so that the installation protrusion 101 enters the installation hole to form a snap connection. Those skilled in the art can conceive of slightly modifying the snap-fit connection between the mounting part 512 and the mounting protrusion 101, and setting it on the top surface of the insulating housing 100, or on the top surface part of the first groove, which does not break away from the scope of the invention.

The installation hole 511 and the installation protrusion 101 may be formed in a substantially rectangular shape.

The unlocking mechanism is shown in Figure 4, the unlocking mechanism includes: an actuating rod 400 passing through the lower part of the fixing part 510 and connected with the handle 300; and a pivoting frame 600 arranged at the connecting part 520 and the insulating housing 100 and is connected to the distal end of the actuating lever 400, so that the pivoting frame 600 is pivoted by pulling the handle 300, thereby jacking up the connecting part 520 and locking Section 530. The pivoting frame 600 includes: a horizontal portion 610 extending along the width direction, the distal end of the actuating rod 400 is connected to the horizontal portion 610; There are two side portions 620 extending downward from the sides, and the two side portions 620 are pivotally connected to the two side surfaces of the insulating housing 100 respectively.

Wherein, the insulating housing includes a main body part 110 and an insertion part 120 inserted into the mating connector, and the junction of the insertion part 120 and the main body part 110 forms a step; the horizontal part 610 and the An auxiliary actuating portion 402 is provided on the opposite side of the actuating rod 400, and the auxiliary actuating portion 402 extends obliquely toward the step.

A second groove 106 is formed on the top surface and both sides of the distal end of the insulating case 100, and the pivot frame is installed in the second groove.

A third groove 105 extending along the length direction is formed on the top surface of the insulating case 100 , and the connecting portion of the actuating rod and the locking mechanism is movably accommodated in the third groove 105 .

As shown in Figures 5 and 6, the locking part 530 has a locking hole 533, and the matching part 210 has a matching protrusion 213 corresponding to the shape of the locking hole 533, and the locking hole 533 goes over the matching The protrusion 213 is sleeved on the matching protrusion 213 .
