Quick-change connectors are widely used in the cooling pipes of new energy vehicles. Different vehicle platforms and models have different battery replacement structures, which often requires battery replacement parts with floating mechanisms to adapt to different vehicle platforms and models. The current floating mechanism uses metal parts and springs to achieve floating and timely return to the center in the X and Y directions. During use, the quick-change connector may experience metal or spring corrosion and wear, affecting the normal use of the quick-change connector and thus the service life of the battery pack. In addition, when installing the quick-change connector at the end of the pack, the main fixing plate and the water pipe adapter need to be connected by a snap-fit ​​connection. The structure is complex and not conducive to improving production efficiency. The main fixing plate and the water pipe adapter need to be sealed with an O-ring, which not only increases the cost but also cannot guarantee the reliability of the seal, which is not conducive to the overall sealing of the water quick-change and affects the service life of the battery pack.

[0038] like Figures 1 to 4 As shown, in the first aspect, the connector assembly of the utility model includes a first connector 1 and a second connector 2, the first connector 1 includes a first mounting plate 10, a floating member 11 connected to the first mounting plate 10, a first mounting seat 12 connected to the floating member 11, and a first pipe 13 connected to the first mounting seat 12; the second connector 2 is connected to the first connector 1, the second connector 2 includes a second mounting plate 20, a second mounting seat 21 connected to the second mounting plate 20, and a second pipe 22 connected to the second mounting seat 21; the second mounting plate 20, the second mounting seat 21 and the second pipe 22 are integrally formed, the second mounting seat 21 includes a first valve core 213 that cooperates with the first connector 1, and the second connector 2 also includes a second valve core 214 connected to the first valve core 213.

[0039] The second mounting plate 20, the second mounting seat 21 and the second piping 22 of the present invention are integrally injection-molded, which not only eliminates the snap-fit ​​structure between the second mounting plate 20 and the second piping 22, simplifies the structure and improves assembly efficiency, but also eliminates the O-ring between the second mounting plate 20 and the second piping 22 through the integral molding of the second mounting plate 20, the second mounting seat 21 and the second piping 22, which not only saves costs but also reduces the sealing path, ensures the reliability of the seal, and thus extends the service life of the battery pack.

[0040] like Figure 1As shown, the first mounting plate 10 of the present invention includes a mounting hole 101, the first mounting plate 10 is provided with a first protrusion 102 facing the floating member 11, the first mounting seat 12 is provided with a second protrusion 121 facing the floating member 11, the floating member 11 is arranged in the mounting hole 101, the floating member 11 includes a through hole 111, the first mounting seat 12 is arranged in the through hole 111, the floating member 11 is provided with a first groove 112 and a second groove 113, the first protrusion 102 is arranged in the first groove 112, and the second protrusion 121 is arranged in the second groove 113.

[0041] like Figure 2 and Figure 4 As shown, the first valve core 213 and the second valve core 214 are connected by welding. In this embodiment, welding can be achieved by using processes such as plastic stir friction welding or laser welding. After the first valve core 213 and the second valve core 214 are welded, the internal structure has a connecting cavity 218 connected to the first joint 1. The first valve core 213 and the second valve core 214 are welded together, which not only reduces the difficulty of the injection molding process, but also ensures the sealing reliability of the valve core through welding.

[0042] like Figures 2 to 4 As shown, the second mounting seat 21 is located on the first side facing the first connector 1, and the second piping 22 is located on the second side away from the first connector 1. The second mounting seat 21 and the second piping 22 are located on different sides of the second mounting plate 20. This not only facilitates the mating of the second mounting seat 21 with the first connector 1, allowing the first valve core 213 and the second valve core 214 to communicate with the first connector 1, but also facilitates the arrangement of the second connector 2 by being located on the second side away from the first connector 1, thereby facilitating the mating installation of the first connector 1 and the second connector 2.

[0044] like Figures 2 to 4 As shown, the main body is provided with an opening 216 arranged in a direction parallel to the axis L of the first valve core 213. The main body is located on one side of the second mounting plate 20 and divides the second mounting plate 20 into an inner side and an outer side. The inner side is the receiving cavity 215, and the outer side is the portion outside the receiving cavity 215. The opening 216 is in communication with the receiving cavity 215 and / or the opening 216 is in communication with the portion outside the receiving cavity 215, which prevents foreign matter or water accumulation in the receiving cavity 215 from affecting the use of the connector assembly. The design of the opening 216 facilitates the discharge of foreign matter or water accumulation, reduces damage to the connector assembly, and extends the service life of the battery pack. There are two first valve cores 213, and the main body includes a connecting portion 211 and a sidewall 212. The connecting portion 211 is located between the two first valve cores 213, and an opening 216 is provided on the connecting portion 211. The opening 216 is provided on the connecting portion 211 to prevent damage to the joint assembly caused by the accumulation of foreign matter or accumulated water, while not affecting the structural strength of the main body and increasing structural stability. In this embodiment, the number of openings 216 is four, and the openings 216 are symmetrically arranged along the axis connecting the second valve cores 214 and symmetrically arranged along a line perpendicular to the axis connecting the second valve cores 214. This not only effectively discharges foreign matter or accumulated water from the receiving cavity 215, but also provides good structural strength by preventing uneven stress on the main body.

[0045] Reference Figure 3 The receiving cavity 215 is provided with a plurality of reinforcing ribs 217 connected to the first valve core 213. In this embodiment, the height of the reinforcing ribs 217 does not exceed the side wall 212, and the height gradually decreases from the first valve core 213 outward. The plurality of reinforcing ribs 217 are evenly distributed along the circumference of the first valve core 213. In this embodiment, each first valve core 213 has six reinforcing ribs 217 evenly distributed along the circumference. The reinforcing ribs 217 provided in the receiving cavity 215 can improve the structural strength of the main body. The reinforcing ribs 217 evenly distributed along the circumference of the first valve core 213 can increase the stability of the structure and prevent damage to the main body due to uneven force.
