[0050] Insertion tube 12, which is located on the socket 1 of the energy storage connector, and a limiting boss 13 is provided on the outer periphery of the end of the insertion tube 12;

[0051] The plug-in cavity 241 is located in the housing 24 of the energy storage connector plug 2. The housing 24 is provided with a relief opening 25 that connects the plug-in cavity 241 with the outside of the housing 24. The relief opening 25 is located at the end of the plug 2.

[0056] When the insert sleeve 12 is inserted into the insertion cavity 241, the outer side of the claw hook 221 acts on the limiting boss 13, causing the claw hook 221 to be lifted and the elastic connection part 23 to be elastically deformed. After the claw hook 221 passes over the limiting boss 13, the elastic deformation of the elastic connection part 23 is restored, and the claw hook 221 limits the limiting boss 13 in the insertion cavity 241, so that the socket 1 and plug 2 that are plugged into each other are locked and connected;

During the plugging process between the plug 2 and the socket 1, the claw hook 221 can be driven to open and reset by the insertion force, and the claw hook 221 is opened by pressing to release the limit on the plug tube 12, so that the locking structure of the energy storage connector is set on the outside, which is convenient for observing the status of the locking structure. At the same time, the locking structure can be integrated into one piece, reducing the assembly process in the production process of the energy storage connector and improving production efficiency.

[0060] Further, if Figure 4As shown, one end of the limiting boss 13 is provided with a guide surface 131 matched with the claw hook 221, and during the insertion of the insertion cylinder 12 into the insertion cavity 241, an external force is applied to the claw hook 221, so that the elastic connecting part 23 is deformed and the claw hook 221 is lifted.

[0062] The elastic connecting part 23 and the elastic claw structure 22 are integrally formed on the shell 24, the cross section of the supporting part 232 is triangular, the connecting position of the supporting part 232 and the claw body 222 is larger in size than the connecting position of the connecting arm 231, so as to ensure the connecting effect and elastic deformation effect of the elastic connecting part 23.

[0063] As shown in the drawings, Figure 4 The supporting part 232 is provided with a through hole 233 penetrating through two sections of the supporting part 232. The through hole 233 provided in the supporting part 232 provides space for the material deformation of the elastic connecting part 23 when deformed, so that the durability of the elastic connecting part 23 is better, and the service life of the elastic claw structure 22 is improved.
