[0061] Please refer to Figure 6-Figure 9 .
[0062] During installation, the second lower box body 82 of the second contact head 8 is inserted into the second opening, and the two ends of the second lower box body 82 slide on the adjacent second elastic sheet 71 and push it to bend, until the second elastic sheet 71 approaches and rebounds to be stuck in the second limiting step 812, and the second elastic sheet 71 fixes the second contact head 8 in the second shell 6 through the second limiting step 812; the second limiting block 74 is slidably inserted into the second limiting groove 824 for fixing, and the second limiting block 74 limits the swing of the second contact head 8 through the second limiting groove 824; the second limiting sheet 72 touches the opening of the second limiting groove 824, so that the second elastic sheet 71 and the second limiting sheet 72 clamp the second contact head 8, and the fourth elastic sheet 73 passes through the second through groove 812 and the third through groove 823 in sequence, thereby completing the assembly of the female head 5;

Only a new second contact 8 needs to be replaced to achieve rapid repair of the female connector 5 of the heavy-loaded connector.
[0064] Please refer to Figure 1 , Figure 3 , Figure 7 and Fig.10 .
[0065] When the male connector 1 is plugged into the female connector 5, the second upper box body 81 of the second contact connector 8 is slidably inserted into the plug-in slot 412, and the fool-proof protrusion 813 is slidably inserted into the fool-proof slide slot 413. The limit of the fool-proof protrusion 813 and the fool-proof slide slot 413 can prevent workers from plugging the male connector 1 and the female connector 5 in reverse, and also facilitate workers to align the male connector 1 and the female connector 5 when plugging them. The protrusion of the third spring piece 33 touches the fourth spring piece 73, so that the third spring piece 33 and the fourth spring piece 73 are gradually bent when the male connector 1 is plugged into the female connector 5, which can increase the friction between the third spring piece 33 and the fourth spring piece 73, and the firmness of the male connector 1 plugged into the female connector 5. The contact area of the first contact pin 43 extends into the second mounting slot, inserts into the contact hole of the second contact pin 83, and is electrically connected.
[0066] The limiting column 211 on the first shell 2 pushes the limiting clip 61 to rotate a certain angle on the second shell 6, so that the limiting column 211 is close to the groove 612 of the limiting clip 61. When the first contact head 4 is plugged into the second contact head 8, the limiting clip 61 loses the push of the limiting column 211, and the torsion spring 611 pushes the limiting clip 61 to reset, so that the limiting column 211 is stuck in the groove 612 of the limiting clip 61, thereby enhancing the firmness of the plug-in connection between the male head 1 and the female head 5; when the male head 1 or the female head 5 is damaged and needs to be repaired, the limiting clip 61 is rotated a certain angle on the second shell 6 by toggling the paddle 613, so that the limiting column 211 loses the limit of the limiting clip 61, and then the male head 1 is removed from the female head 5.
[0067] The utility model provides a heavy-duty connector that is easy to install and disassemble. When the male and female heads of the heavy-duty connector are assembled, it is only necessary to install the first limiting member in the first shell of the male head, and then push the first contact head with the first pin installed into the first shell from the first opening, the first contact head touches the first limiting piece, and the first elastic sheet is snapped into the first limiting step so that the first elastic sheet and the first limiting sheet clamp the first contact head; install the second limiting member in the second shell of the male head, and then push the second contact head with the second pin installed into the second shell from the second opening, the second contact head touches the second limiting piece, and the second elastic sheet is snapped into the second limiting step so that the second elastic sheet and the second limiting sheet clamp the second contact head; the first contact head of the male head is fixed to the first shell by snapping with the first limiting piece, and the second contact head of the female head is fixed to the second shell by snapping with the second limiting piece, which is convenient for workers to assemble the heavy-duty connector and improves the efficiency of assembling parts;
[0068] When the heavy-load connector is damaged, the male head is separated from the female head, and the first spring sheet is moved to make the first limiting step lose the limiting position of the first spring sheet, and the damaged first contact head is taken out from the first shell, and a new first contact head is pushed into the first shell, so that the first spring sheet and the first limiting sheet clamp the new first contact head; the second spring sheet is moved to make the second limiting step lose the limiting position of the second spring sheet, and the damaged second contact head is taken out from the second shell, and a new second contact head is pushed into the second shell, so that the second spring sheet and the second limiting sheet clamp the new second contact head, thereby realizing the rapid replacement of damaged parts and improving the work efficiency of workers in repairing heavy-load connectors.
