A sealing gasket 53 is arranged on the female socket 5. The female socket 5 is formed with a first retaining edge 511 protruding outward on the outside. The first retaining edge 511 is provided with a first hole 512 through the front and rear end surfaces for the locking screw to pass through; the male connector 700 includes an angled plug 7 and a second wire 8 fixedly connected to the angled plug 7 and perpendicular to the plug-in direction of the angled plug 7. A waterproof sealing ring 73 is arranged on the angled plug 7; after the angled plug 7 is plugged into the socket 501 of the female socket 5, the waterproof sealing ring 73 is sealed against the inner wall of the socket 501. Contact, thereby forming a sealing and waterproof function, so that the two form a stable and reliable electrical conduction, and the first wire 6 and the second wire 8 are perpendicular to each other and conduct each other, realizing 90-degree bending wiring to meet the use requirements; after the female seat 5 is embedded and installed in the window of an object (such as a battery shell, etc.), the first retaining edge 511 is against the outside of the window of the object, and the locking screw passes through the first hole 512 and is spirally fixed to the object, and the first retaining edge 511 forms a sealed assembly with the object through the sealing gasket 53, thereby ensuring that the large-current easy-to-replace waterproof connector of the utility model forms a sealed and waterproof assembly with the object, which can prevent the formation of a gap between them and cause water leakage and other problems, thereby ensuring the sealing and waterproof function of the utility model. That is to say, the utility model adopts a female connector 500 and a male connector 700 that can be plugged in and connected to replace the traditional right-angle adapter (see background technology), and the female socket 5 is separately embedded and installed in the window of an object (such as a battery casing, etc.), and the female socket 5 is locked to the object by a locking screw, and the first retaining edge 511 in the female socket 5 forms a sealed assembly with the object through a sealing gasket 53, thereby ensuring that the large-current easily disassembled and replaced waterproof connector of the utility model forms a sealed and waterproof assembly with the object, which can prevent the formation of a gap therebetween and cause problems such as water leakage, thereby ensuring the sealing and waterproof function of the utility model. At the same time, after the angled plug 7 is plugged into the socket 501 of the female socket 5, the waterproof sealing ring 73 is in sealing contact with the inner wall of the socket 501, thereby forming a sealing and waterproof function, so that the two form a stable and reliable electrical conduction; when the angled plug 7 in the male connector 700 or the first interface connected to the first wire 6 is damaged, the male connector 700 can be directly pulled out relative to the female socket 5, and then replaced with a new male connector 700, without disassembling the female socket 5.

[0035] Correspondingly, the angle plug 7 includes a right-angled insulator 71 and a plurality of male terminals 72 fixed in the insulator 71. The front end of the insulator 71 has a docking convex ring 713 adapted to the insertion space 510. The male terminals 72 are exposed in the docking convex ring 713, and the waterproof sealing ring 73 is sleeved on the outer surface of the docking convex ring 713.

When the conductor part of the first wire 6 is embedded in the wiring groove 522 at the rear end of the female terminal 52, it is fixed by soldering, thereby ensuring that the conductor part of the first wire 6 forms a stable conduction with the female terminal 52, and the solder is also filled into the notch step 523, thereby making the solder stably connected to the female terminal 52, thereby ensuring that the conductor part of the first wire 6 is connected to the female terminal 52 more stably. In addition, since the wiring groove 522 is isolated from the guide groove 521, when the conductor part of the first wire 6 is embedded in the wiring groove 522 at the rear end of the female terminal 52, it will not enter the guide groove 521, thereby ensuring that the size of the guide groove 521 remains unchanged.

[0037] The number of the docking tubes 513 is at least two, and a gap is formed between two adjacent docking tubes 513; at least two mutually spaced slots 714 are formed in the docking convex ring 713, each of the slots 714 has a male terminal 72, and a docking tube 513 is plugged and fixed to a slot 714, thereby effectively enhancing the plugging and unplugging force.

[0038] An annular groove 715 is provided on the outer surface of the docking convex ring 713, and the inner side of the waterproof sealing ring 73 is embedded in the annular groove 715 to ensure the stability between the two, wherein the outer side of the waterproof sealing ring 73 protrudes outside the annular groove 715 to form a sealed contact with the female seat, and at least two waterproof convex ribs 731 are provided on the outer side of the waterproof sealing ring 73, which has a better sealing assembly effect.

[0039] The insulator 71 is provided with anti-slip grooves 716 for easy pinching or holding. When the staff needs to pull out the male connector 700 relative to the female connector 500, when pinching or holding the insulator 71 of the angled plug 7, the fingers are pressed into the anti-slip grooves 716, so that the staff can exert force better, and then the angled plug 7 can be pulled out relative to the female socket better and more smoothly, which is more convenient to use.

[0040] The cross section of the anti-slip groove 716 is arc-shaped, which can make the human hand feel more comfortable and avoid injury to the human hand.

[0041] An SR head 717 is provided between the insulator 71 and the second wire 8 , and a plurality of slots 718 are provided on the periphery of the SR head 717 for facilitating swinging, which can effectively prevent the second wire 8 from breaking during the swinging process relative to the insulator 71 .

[0042] To sum up, the utility model adopts a female connector 500 and a male connector 700 that can be plugged in and connected to replace the traditional right-angle adapter (see background technology), and the female socket 5 is separately embedded and installed in the window of an object (such as a battery casing, etc.), and the female socket 5 is locked to the object by a locking screw, and the first retaining edge 511 in the female socket 5 forms a sealed assembly with the object through a sealing gasket 53, thereby ensuring that the large-current easily disassembled and replaced waterproof connector of the utility model forms a sealed and waterproof assembly with the object, which can prevent the formation of a gap therebetween and cause problems such as water leakage, thereby ensuring the sealing and waterproof function of the utility model. At the same time, after the angled plug 7 is plugged into the socket 501 of the female socket 5, the waterproof sealing ring 73 is in sealing contact with the inner wall of the socket 501, thereby forming a sealing and waterproof function, so that the two form a stable and reliable electrical conduction; when the angled plug 7 in the male connector 700 or the first interface connected to the first wire 6 is damaged, the male connector 700 can be directly pulled out relative to the female socket 5, and then replaced with a new male connector 700, without disassembling the female socket 5.
