As shown in fig. 1-4, an electric vehicle power connector includes a male end 100 and a female end 200, the male end 100 includes a housing 120 and a terminal 110, the female end 200 includes a base 210, a jack (not shown) provided at an upper end of the base 210 and corresponding to the terminal 110 of the male end 100, and six electrically connecting metal rods 230 provided at a lower end of the female end 200. The male end 100 is inserted into the female end 200. The female terminal 200 is disposed in the housing 300, and as an external interface of the battery, a circuit board 330 is disposed in the battery, and six electrical connection holes 340 are opened on the circuit board 330, and the electrical connection metal rods 230 of the female terminal 200 are inserted into the electrical connection holes 340 in a one-to-one correspondence.

The connector provided by the embodiment omits a connecting line in the connection between the female end 200 and the circuit board 330, and is directly connected with the circuit board 330 through the electric connecting metal rod 230, so that the problem of unstable connection of the connecting line is solved, and the potential safety hazard caused by unstable connection of the connecting line is eliminated. And the overcurrent capacity of the connecting wire is limited by the size of the wire harness, but the electric connection metal rod 230 does not have the problem, and the current can be adjusted in a reasonable range.

The housing 300 includes an upper cover 310 and a lower cover 320, and the female terminal 200 and the circuit board are disposed in the housing 300 and are engaged with each other by the upper cover 310 and the lower cover 320. The upper cover 310 is provided with a through hole 350, and the upper end of the female terminal 200 provided with the insertion hole is inserted into the through hole 350 from the lower side of the upper cover 310, so that the male terminal 100 can be inserted into the female terminal 200 from the upper side of the upper cover 310 from the outside. A circle of outer convex eaves 240 is arranged outside the middle part of the base 210 of the female end 200, the diameter of the outer convex eaves 240 is larger than that of the through hole 350, so that the outer convex eaves 240 can be clamped on the lower end wall of the through hole 350, and the lower cover 320 is covered with the upper cover 310 from the lower part of the female end 200 upwards, so that the female end 200 is fixed in the shell 300.

The outer side of the base 210 of the female end 200 is sleeved with a waterproof sealing ring 600 above the outer convex eaves 240, and the waterproof sealing ring 600 is provided with more than one convex ring 610 along the vertical direction. Traditional female end 200 sets up a sealed pad with casing 300 water proof seal at female end 200, adopts the terminal surface waterproof, however, in the use, sealed pad can atress arch to water-proof effects is not good. This embodiment adopts the lateral wall waterproof mode, establishes the lateral wall at base 210 through waterproof sealing ring 600 cover, reduces waterproof sealing ring 600's atress, and through setting up a plurality of protruding rings 610, promotes water-proof effects.

The female terminal 200 has a first connection hole 410 formed at two positions opposite to each other at a lower end edge thereof, and a second connection hole 420 formed at a position of the circuit board 330 corresponding to the first connection hole 410, and is provided with a bolt to be locked into the second connection hole 420 and the first connection hole 410. The base 210 and the circuit board 330 are locked together by the bolts at the female end 200, which increases the connection stability of the base 210 and the circuit board 330.

The lower end of the female end 200 is provided with two positioning protruding rods 510 at two positions, the circuit board 330 is provided with positioning holes 520 at positions corresponding to the positioning protruding rods 510, and when the base 210 is connected with the circuit board 330, the positioning protruding rods 510 and the positioning holes 520 play an auxiliary role in positioning.

The male end 100 and the female end 200 need to be very corresponding in the plugging process so as not to damage the spring in the female end 200, but in reality, the male end 100 and the female end 200 cannot be absolutely corresponding in manual plugging, and the terminal 110 of the male end 100 easily punctures the spring in the female end 200, so that the plugging of the connector has the service life limitation of the use times. In order to increase the number of times of inserting the male terminal 100 and the female terminal 200, a soft rubber pad (not shown) surrounding the circumference of the ring terminal 110 is disposed at the joint of the terminal 110 and the housing 120 of the male terminal 100, and a soft rubber pad is disposed at the position of the spring in the jack along the circumferential direction. The soft rubber pad has certain elasticity, and when the terminal 110 is incompletely inserted into the jack correspondingly, the soft rubber pad enables the terminal 110 and the spring to have certain displacement space, so that the spring cannot be punctured, and the service life of the connector is prolonged.

In the connector provided by the embodiment, a connecting wire is not used between the female terminal 200 and the circuit board 330, so that the potential safety hazard of unstable connection of the connecting wire is eliminated. And the end face is waterproof, so that the vertical side face waterproof mode is changed, and the waterproof effect is improved. Soft rubber pads are arranged at corresponding positions of the male end 100 and the female end 200, so that the service life of the connector male end 100 and the connector female end 200 in opposite insertion is prolonged.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
