In an alternative embodiment, when the male connector 20 is inserted into the female connector 10, the second sliding protrusion 203 of the male connector 20 slides along the second sliding groove 127 of the locking ring 12, the second sliding protrusion 203 abuts against the linkage plate 153, the linkage plate 153 moves along with the male connector 20, the linkage plate 153 drives the cover plate main body 151 to move, the linkage plate 153 drives the first sliding protrusion 152 to slide along the first sliding groove 125 and the first through hole 1241, the limit protrusion 154 on the cover plate 15 is separated from the first recess 1262, when the limit protrusion 154 on the cover plate 15 is clamped in the second recess 1263, the two-dimensional code is exposed and can be identified, so that it can be known that the clamping groove 202 of the male connector 20 is clamped with the clamping spring 13 of the female connector 10, the female connector 10 and the male connector 20 are assembled in place, and the assembly qualification rate of the VDA standard connection connector can be improved.

Optionally, as shown in fig. 3, the female connector 10 further includes a second sealing ring 16, the second sealing ring 16 is mounted on the female connector body 11, and the second sealing ring 16 is used for sealing the female connector 10 and a cooling pipe of the battery pack cooling system.

Wherein the second sealing ring 16 may be a rubber ring.

The embodiment of the invention provides a vehicle, which comprises a battery pack cooling system, a whole vehicle system and a VDA standard connecting joint; the VDA standard connector is connected between a cooling pipeline of a battery pack cooling system and a pipeline of a whole vehicle system.

The VDA standard connection connector in this embodiment has the same structure as the VDA standard connection connector provided in any of the above embodiments, and can bring about the same or similar technical effects, and details are not repeated herein, and reference may be specifically made to the description of the above embodiments.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
