[0020] Figure 1 This is an exploded view of this utility model; Figure 2 This is a schematic diagram of the structure of this utility model; Figure 3 This is a schematic diagram of the structure of the interlocking plug-in of this utility model; Figure 4 This is a schematic diagram of the interlocking terminal of this utility model.

[0021] Combined with appendix Figure 1 and attached Figure 2As shown, an MSD socket assembly for an energy storage system includes a socket housing 1, a power terminal 2, and an interlocking terminal 3. The power terminal 2 and the interlocking terminal 3 are installed inside the socket housing 1. A stud 4 is fixed inside the socket housing 1. The power terminal 2 has a through hole through which the stud 4 passes. Hook 1 5 is provided on the left and right sides of the power terminal 2. Hook 2 6 is provided in the slot of the socket housing 1. Hook 1 5 and hook 2 6 are engaged together. The power terminal 2 is placed in the slot of the socket housing 1. The interlocking terminal 3 is installed in the interlocking plug 7, which is installed inside the socket housing 1.

[0022] When installing power terminal 2, directly insert power terminal 2 into the slot of socket housing 1, with stud 4 passing through the through hole on power terminal 2. After power terminal 2 is installed in place, hook 1 5 and hook 2 6 will interlock together, achieving the connection between socket housing 1 and power terminal 2. Finally, insert interlock terminal 3 into interlock plug 7, and then insert interlock plug 7 into slot 2 of socket housing 1 to complete the installation.

[0023] As attached Figure 4 As shown, the interlock terminal 3 is equipped with a spring piece 8, and the interlock plug-in 7 has a slot 9, in which the spring piece 8 is placed. When the interlock terminal 3 is inserted into the interlock plug-in 7, the spring piece 8 is in a pressed state. When the interlock terminal 3 is fully inserted, the spring piece 8 will spring up from the slot 9 and lock into the slot 9, preventing the interlock terminal 3 from exiting the interlock plug-in 7.

[0024] As attached Figure 3 As shown, the interlocking plug 7 has a notch 10 inside, and a cover plate 11 for covering the notch 10 is movably connected to one side of the notch 10.

[0025] The notch 10 is provided with a spacer 12, and the cover plate 11 is provided with a groove 13 for matching the spacer 12.

[0026] A hook 3 14 is provided on one side of the notch 10, and a protrusion 15 for engaging the hook 3 14 is provided on the outer side of the cover plate 11.

[0027] The interlock terminal 3 is provided with a protrusion 17 for pressing against the cover plate 11.

[0028] After the interlock terminal 3 and the interlock plug 7 are in place, swing the cover plate 11 toward the notch 10 until the cover plate 11 covers the notch 10. At this time, the hook 14 on one side of the notch 10 hooks onto the protrusion 15 on the cover plate 11, and the spacer 12 is embedded in the groove 13 on the cover plate 11. The protrusion 15 is now pressing against the cover plate 11, thus completing the connection between the interlock terminal 3 and the interlock plug 7.

[0029] The interlocking plug 7 has spring pieces 16 on both the left and right sides, and the socket housing 1 has a slot 2. The slot 2 has a step for holding the spring pieces 16 in place, and the interlocking plug 7 is placed in the slot 2.

[0030] When the interlocking plug 7 is inserted into the second slot, the spring piece 16 is in a pressed state. When the spring piece 16 passes the step in the second slot, it will spring open, so that the spring piece 16 presses against the step, thus preventing the interlocking plug 7 from exiting the socket housing 1.

[0031] The interlocking plug 7 has an opening 18 at its tail end for inserting the interlocking terminal 3. The interlocking terminal 3 is inserted into the interlocking plug 7 through the opening 18.
