[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Example:

[0029] A quick-connect connector for a battery pack cooling system, such as Figure 1-11 As shown, it comprises a housing 1, an inner sealing ring 2 is arranged in the housing 1, a retaining ring 3 is inserted at the lower end of the housing 1, and a male connector 4 is inserted at the lower end of the retaining ring 3;

[0030] A clamping boss 33 is provided at the lower end of the retaining ring 3 , and a clamping groove 41 is provided on the male connector 4 . The clamping boss 33 is clamped and connected with the clamping groove 41 .

[0031] In a possible implementation manner, the locking boss 33 is controlled to open and close by the button 32 .

[0032] In a possible implementation, the housing 1 adopts an L-shaped structure, a sealed inner hole 11 is opened at the connection between the horizontal section and the vertical section, and the inner sealing ring 2 is sleeved in the sealed inner hole 11 .

[0033] In a possible implementation manner, two guide grooves 12 are symmetrically provided inside the vertical section of the housing 1 , and the upper end of the retaining ring 3 slides along the guide grooves 12 .

[0034] In a possible implementation, two limit buckles 13 are symmetrically provided on the side wall of the vertical section of the shell 1 , and two limit bosses 31 are symmetrically provided on both sides of the upper end of the retaining ring 3 , and the two limit bosses 31 are respectively clamped in the two limit buckles 13 .

[0035] In a possible implementation manner, two connecting arms 34 are symmetrically provided on the outer side of the retaining ring 3 , and the two connecting arms 34 are respectively assembled to the housing 1 along the two guide grooves 12 .

[0036] Working principle, see Figure 1-11There is a sealed inner hole 11 and two guide grooves 12 inside the shell 1, two limit buckles 13 are provided on both sides of the shell 1, the retaining ring 3 has two limit bosses 31, two buttons 32, two clamping bosses 33 and two connecting arms 34, and there is a clamping groove 41 on the male connector 4. During assembly, the inner sealing ring 2 is installed into the shell 1 along the sealed inner hole 11, and then the connecting arm 34 is assembled to the shell 1 along the guide groove 12.

[0037] When the limiting boss 31 and the limiting buckle 13 are fully engaged and assembled into place, the male connector 4 is inserted into the sealing inner hole 11 until it can no longer be pushed. During this assembly process, the engaging boss 33 can be stretched open until the engaging boss 33 and the engaging groove 41 are fully engaged. At this time, the engaging boss 33 rebounds and the male connector cannot move further. Press and hold the two buttons 32 at the same time, and the engaging boss 33 is deformed to both sides. At this time, the male connector 4 can continue to move. When the engaging boss 33 and the engaging groove 41 are fully engaged, the male connector 4 cannot be directly withdrawn, and the assembly is completed.

[0038] After adopting the above technical solution, the utility model has the following advantages:

[0039] 1. Compared with the rigid connection, the retaining ring 3 and the male connector 4 are of elastic clamping structure, and the male connector 4 will not fall off due to slight vibration or external force.

[0040] 2. The product is small in size, allowing installers to better arrange the pipelines in the already narrow installation space of the energy storage pipeline and avoid interference during the arrangement process.

[0041] 3. The product has a simple structure and can cope with various situations during actual use, saving mold opening costs and also making it convenient for assemblers to assemble.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
