A waterproof insulating sleeve 101 is sleeved on the surface of the conductive copper sheet 102 to form an insulating layer on the surface of the conductive copper sheet 102. The anti-electric shock component consists of a limit plate 107, a matching groove 116, a special-shaped screw 122 and an insulating rod 121, and the insulating rod 121 is made of insulating material.Insert the waterproof rubber ring 106 into the second limiting groove 110, and then fix the first anti-detachment sleeve 104 on the surface of the first waterproof shell 103. The first anti-detachment sleeve 104 can be fixed to prevent it from shaking or rotating through the cooperation of the first triangular block 105 and the first anti-detachment sleeve 104. At the same time, the waterproof rubber ring 106 is limited. The nut 108 is placed in the first waterproof shell, and the conductive ring 120 is placed in the fixing ring 125. The anti-electric shock component is passed through the conductive ring 120 and the conductive copper sheet 102 hole features. In this way, the conductive copper sheet 102 and the conductive ring 120 passing through the first limiting groove 109 are tightly connected together through the threaded structure of the nut 108 and the special-shaped screw 122. A stable conductive path is formed.

The waterproof pad 209 and the second waterproof shell 201 and the customer's installation panel are interference fit to form a waterproof surface, thus forming effective waterproofing. The waterproof pad 209 is inside the second waterproof shell 201, so that the waterproof pad 209 has no displacement in the up and down directions in the second waterproof shell 201. At the same time, there is a certain gap between the installation screws 203 and the second waterproof shell 201, so that the second waterproof shell 201 and the waterproof pad 209 have a certain displacement in the front, back, left and right directions relative to the installation screws 203, forming a certain floating amount, while taking waterproofing into account.

[0023] The inner wall of the second waterproof shell 201 is slidably connected to the surface of the first waterproof shell 103; after the connection, the outer side of the sealing rubber ring 117 in the plug assembly abuts against the bottom of the second waterproof shell 201, and at the same time, the inner side of the sealing rubber ring 117 abuts against the fixing ring 125, forming effective waterproofing.
[0024] By slidably connecting the inner wall of the second waterproof housing 201 with the surface of the first waterproof housing 103 , the plug component 1 can be plugged into the socket component 2 , which is convenient for installation.
[0025] A waterproof pad 209 is fixedly installed on the rear side of the second waterproof housing 201, and mounting screws 203 are provided at the four corners of the front side of the second waterproof housing 201; The waterproof pad 209 and the second waterproof shell 201 are interference fit to form a waterproof surface, thereby forming effective waterproofing.

The new connector structure greatly shortens the distance L from the center of the plug to the tail, reduces the overall volume, reduces the types of parts, thereby reducing costs, facilitating assembly, and requiring less space, which can meet customers' increasingly high requirements for battery integration.
[0026] The surface thread sleeve of the special-shaped screw 122 is provided with a nut 108 .
[0027] A sealing rubber ring 117 is installed on the top of the plug housing 118, and the top of the sealing rubber ring 117 abuts against the bottom of the first waterproof housing 103; The second triangular clamping block 124 and the clamping ring 126 are used in combination to prevent the plug housing 118 from being easily separated from the first waterproof housing 103 . The sealing rubber ring 117 is provided to prevent water from entering the plug housing 118 , thereby improving safety.
[0028] The top of the insulating rod 121 is fixedly connected to the limiting plate 107, the bottom of the limiting plate 107 is in contact with the top of the matching groove 116, and the surface of the insulating rod 121 is slidably connected to the inner wall of the insulating sleeve 210; The anti-electric shock component is composed of a limiting plate 107, a matching groove 116, a special-shaped screw 122 and an insulating rod 121. The nut 108 is placed in the first waterproof shell, and the conductive ring 120 is placed in the fixing ring 125. The anti-electric shock component is then passed through the hole features of the conductive ring 120 and the conductive copper sheet 102. The threaded structure of the nut 108 and the special-shaped screw 122 cooperates to tightly connect the conductive copper sheet 102 and the conductive ring 120 through the first limiting groove 109 to form a stable conductive path. By cooperating with the first limiting groove 109 set on the first waterproof shell 103 and the anti-electric shock component, the anti-electric shock component can be fixed to prevent it from shaking or rotating.
[0029] When assembling a waterproof connector of the present invention, a conductive copper sheet 102 is first used to replace the traditional cable for conduction. A waterproof insulating sleeve 101 is sleeved on the surface of the conductive copper sheet 102 to form an insulating layer on the surface of the conductive copper sheet 102. The conductive copper sheet 102 with the waterproof insulating sleeve 101 is passed through the waterproof rubber ring 106 and the first anti-detachment sleeve 104 and then placed in the first limiting groove 109 of the first waterproof housing. The anti-electric shock component is composed of a limiting plate 107, a matching groove 116, a special-shaped screw 122 and an insulating rod 121. The insulating rod 121 is made of insulating material. The waterproof rubber ring 106 is inserted into the second limiting groove 110, and then the first anti-detachment sleeve 104 is inserted into the second limiting groove 110. It is fixed on the surface of the first waterproof shell 103. Through the cooperation of the first triangular clamp block 105 and the first anti-detachment sleeve 104, the first anti-detachment sleeve 104 can be fixed to prevent it from shaking or rotating, and at the same time, the waterproof rubber ring 106 is limited. The third party puts the nut 108 into the first waterproof shell, and then puts the conductive ring 120 into the fixing ring 125, and then passes the anti-electric shock component through the hole features of the conductive ring 120 and the conductive copper sheet 102. The threaded structure of the nut 108 and the special-shaped screw 122 cooperates to tightly connect the conductive copper sheet 102 and the conductive ring 120 through the first limiting groove 109, so as to form a stable conductive path.The first limiting groove 109 provided on the first waterproof shell 103 cooperates with the anti-electric shock component to fix the anti-electric shock component to prevent it from shaking or rotating. The waterproof rubber ring 106 is provided so that after the anti-electric shock component, the first anti-detachment sleeve 104 and the first waterproof shell 103 are assembled, the contact between the first anti-detachment sleeve 104 and the anti-electric shock component prevents water from entering from the gap between the waterproof insulating sleeve 101 and the first waterproof shell. The conductive ring 120 is fixed on the plug shell 118, and then the first conductive sleeve 119 is fixed on the surface of the conductive ring 120, so that the first conductive sleeve 119 is installed on the plug shell 118 to form a conductive combination A. At this time, the conductive combination A is placed in the first waterproof shell 103, and then the anti-electric shock component 103 is placed in the first waterproof shell 103. The conductive combination A and the conductive copper sheet 102 are passed through, and the nut 108 and the matching groove 116 are tightened to make the conductive combination A, the anti-electric shock component and the conductive copper sheet 102 tightly connected. When the anti-electric shock component passes through the conductive combination A and the conductive copper sheet 102, the fixing ring 125 is inserted into the plug shell 118. Through the cooperation of the second triangular clamping block 124 and the clamping ring 126, the plug shell 118 cannot be easily separated from the first waterproof shell 103. Through the sealing rubber ring 117, it is difficult for water to enter the plug shell 118, thereby improving safety. Through the cooperation of the insulating rod 121 and the socket shell 118, the fingers cannot easily touch the conductive ring 120, thereby avoiding electric shock and improving safety. The spring 123, the support plate 111, the third triangular block 112, the third limiting groove 113, the button 114 and the connecting groove 115 are used in combination to form a locking structure of the button 114. The conductive plate 202 is tightly matched with the second waterproof shell 201 by in-mold injection molding, and cannot be easily removed from the second waterproof shell 201. The fixed rod 206 formed by injection molding completes the fixation of the insulating sleeve 210 and the conductive plate 202. The conductive tube 207 is blocked by the set insulating sleeve 210. The cooperation with the second waterproof shell makes it difficult for fingers to touch the conductive tube 207, thereby avoiding electric shock and improving safety. The waterproof pad 209 and the second waterproof shell 201 and the customer installation panel are interference-fitted to form a waterproof surface. To achieve effective waterproofing, the plane of the mounting screw 203 and the second waterproof housing 201 is a sliding fit, so that the second waterproof housing 201 and the waterproof pad 209 have no front-to-back displacement relative to the customer's mounting panel and the mounting screw 203. At the same time, there is a certain gap between the mounting screw 203 and the second waterproof housing 201, so that the second waterproof housing 201 and the waterproof pad 209 have a certain displacement in the up, down, left and right directions relative to the customer's mounting panel and the mounting screw 203, forming a certain floating amount, while taking waterproofing into account. The new connector structure greatly shortens the distance L from the center of the plug to the tail, reduces the overall volume, reduces the types of parts, thereby reducing costs, is easy to assemble, requires less space, and can meet customers' increasingly high requirements for battery integration.
