Two of the surface-mount power terminals 4 are installed within the front core 2 via insulating sleeves 5, and a fuse 6 is connected to the rear end of each surface-mount power terminal 4. An adapter terminal 7 is connected to the rear end of the fuse 6. The adapter terminal 7 includes a clamp 8 and a crimping foot 9 located at the lower end of the clamp 8. The wire is crimped with the crimping foot 9. A set of elastic contacts 10 connected to the fuse 6 is provided on the side wall of the clamp 8. The fuse 6 can be connected to the adapter terminal 7 by inserting its rear end into the clamp 8. A bushing 11 is provided at the upper end of the tail cap 26, embedded in the front core 2. The crimping foot 9 is located within the bushing 11 to improve the assembly stability of the adapter terminal 7. The above structure enables the replaceable assembly of the chip power terminal 4 while ensuring structural stability.

[0015] Preferably, the lower end of the clamp 8 is provided with a terminal block 13 with a screw hole 12, and the crimping foot 9 is connected to the terminal block 13 and fixed by inserting a screw into the screw hole 12. The bushing 11 is provided with a positioning slot 14, and the lower end of the terminal block 13 is inserted into the positioning slot 14 to further improve the assembly stability of the adapter terminal 7.

[0016] Preferably, the insulating sleeve 5 has a slot 15 for inserting and engaging with the surface-mount power terminal 4, and the insulating sleeve 5 has clips 16 and guide rails 17 on both sides. The front rubber core 2 has a slot 18 for connecting with the clips 16 and a guide rail groove 19 for engaging with the guide rails 17. The surface-mount power terminal 4 can be plugged into the slot 15. This structure enables a quick and precise connection between the insulating sleeve 5 and the front rubber core 2.
