[0092] According to an embodiment of the first aspect of the present application, with reference to Figures 1 - 7As shown in the figure, the present application provides a plug, including: a plug body 100, a male terminal 101, a first sealing structure 102 and a first end cap 103. Among them, the plug body 100 has a first end 104, and the first end 104 is provided with a first opening 105; the male terminal 101 is arranged inside the plug body 100, the male terminal 101 has a first wiring structure, and the first wiring structure faces the first opening 105; the first sealing structure 102 is arranged at the first opening 105, and the first sealing structure 102 is provided with a first wire pressing hole structure 106 corresponding to the first wiring structure of the male terminal 101; the first end cap 103 is connected to the first opening 105 and covers the first sealing structure 102, and the first end cap 103 is provided with a first wire passing hole structure 107 corresponding and communicating with the first wire pressing hole structure 106.

[0093] In this embodiment of the present application, the plug body 100 is the carrier part of the whole device. It has a first end 104, and a first opening 105 is provided at this end, which is convenient for the installation of the male terminal 101.

[0094] The male terminal 101 is located inside the plug body 100, and has a first wiring structure facing the first opening 105. This design enables the wire to be connected to the first wiring structure of the male terminal 101 by accessing from the direction of the first opening 105.

[0095] The first sealing structure 102 is installed at the first opening 105, and it is provided with a first wire pressing hole structure 106 corresponding to the first wiring structure of the male terminal 101. This wire pressing hole structure can not only ensure that the wire is correctly connected to the first wiring structure of the male terminal 101, but also be tightly compressed when the wire passes through the wire pressing hole structure, so as to form a good physical seal and prevent moisture intrusion to achieve the sealing effect.

[0096] The first end cap 103 is connected and covers the first opening 105, and also covers the first sealing structure 102. It is also provided with a first wire passing hole structure 107, which is matched with the first wire pressing hole structure 106 on the first sealing structure 102 to ensure that the wire can pass through smoothly without affecting the sealing performance.

[0097] Therefore, the embodiment of the present application can effectively improve the sealing and waterproof performance of the plug, thereby improving the safety and reliability, and the assembly is convenient.

[0098] According to an embodiment of the present application, referring to Figures 1 - 4As shown, the male terminal 101 includes a pair of first male terminals 108. The first wiring structure includes a first wiring portion 109, and each first male terminal 108 has a first wiring portion 109. The first sealing structure 102 includes a pair of first gaskets 110. The first wire pressing hole structure 106 includes a first wire pressing hole 111. Each first gasket 110 is correspondingly sealed to the first wiring portion 109 of each first male terminal 108, and each first gasket 110 is provided with a first wire pressing hole 111 corresponding to each first wiring portion 109. The first wire passing hole structure 107 of the first end cap 103 includes a pair of first wire passing holes 112, and each first wire passing hole 112 corresponds to each first wire pressing hole 111 one by one. It can be understood that the pair of first male terminals 108 are the positive male terminal and the negative male terminal.

[0099] Specifically, the wire passes through the first wire passing hole 112 of the first end cap 103, then passes through the first wire pressing hole 111 on the first gasket 110, and is electrically connected to the first wiring portion 109 of the first male terminal 108.

[0100] The design of the first wire pressing hole 111 can ensure that the wire is properly compressed when passing through, so as to form a tight contact between the wire and the hole, reducing the possibility of moisture or other contaminants entering. The first gasket 110 itself can be made of waterproof material to further enhance the sealing effect. The use of the first end cap 103 not only provides additional physical protection, but also strengthens the sealing effect through the precise matching of the first wire passing hole 112 and the first wire pressing hole 111 thereon.

[0101] Due to the double sealing measures of the first gasket 110 and the first end cap 103, even in a harsh environment, it can effectively prevent moisture from entering the plug interior and protect the circuit from damage.

[0102] Therefore, through the above design, the embodiment of the present application effectively improves the sealing and waterproof performance of the plug, ensuring the stability and safety of the electrical connection.

[0103] According to an embodiment of the present application, with reference to Figures 1 - 3 and Figure 5As shown, the male terminal 101 further includes a plurality of second male terminals 113. The currents or signals transmitted by the second male terminals 113 are different from those transmitted by the first male terminals 108. The first wiring structure further includes a second wiring portion 114, and each second male terminal 113 has a second wiring portion 114. The first sealing structure 102 further includes a second gasket 115, and the first wire pressing hole structure 106 further includes a second wire pressing hole 116. The second gasket 115 seals the second wiring portion 114 of each second male terminal 113, and the second gasket 115 is provided with a second wire pressing hole 116 corresponding to each second wiring portion 114. The first wire passing hole structure 107 of the first end cap 103 further includes a plurality of second wire passing holes 117, and each second wire passing hole 117 corresponds to each second wire pressing hole 116 one by one. In this example, the male terminal 101 may include four second male terminals 113, and the four second male terminals 113 are provided between a pair of first male terminals 108. Of course, the number of the second male terminals 113 may also be more, and specific design adjustments can be made according to actual requirements.

[0104] Specifically, the wire passes through the second wire passing hole 117 of the first end cap 103, then passes through the second wire pressing hole 116 on the second gasket 115, and is electrically connected to the second wiring portion 114 of the second male terminal 113.

[0105] By integrating the first male terminals 108 and the second male terminals 113, the plug of the present application enables the plug to support multiple types of current or signal transmissions, increasing its scope of application and functionality.

[0106] The design of the second wire pressing hole 116 ensures that the wire is properly compressed when passing through, thereby forming a tight contact between the wire and the hole and reducing the possibility of moisture or other contaminants entering. The second gasket 115 can be made of a waterproof material to further enhance the sealing effect. The first end cap 103 not only provides additional physical protection, but also strengthens the sealing effect through the precise matching of the second wire passing hole 117 and the second wire pressing hole 116 thereon, and can effectively prevent moisture from entering the interior of the plug and protect the circuit from damage.

[0107] Therefore, through the above design, the embodiment of the present application can not only provide a plurality of male terminals for different purposes, but also ensure the sealing and waterproof performance of all terminals, thereby ensuring the reliability and safety of the connector in various application environments.

[0108] According to an embodiment of the present application, with reference to Figures 1 - 7 As shown, each first male terminal 108 further has a first contact portion 118 connected to the first wiring portion 109, and each second male terminal 113 further has a second contact portion 119 connected to the second wiring portion 114.

[0109] The plug body 100 includes a connected first mounting portion 120 and a first plugging portion 121. The first mounting portion 120 has a first end 104. The first mounting portion 120 is provided with a pair of first mounting cavities 122 and a second mounting cavity 123 that communicate with a first opening 105. Each first mounting cavity 122 is used to mount the first wiring portions 109 of the respective first male terminals 108 one by one, and the second mounting cavity 123 is used to mount the second wiring portions 114 of the respective second male terminals 113. The first plugging portion 121 is used to plug into a socket. The first plugging portion 121 is provided with a third mounting cavity 124. The first contact portions 118 of the respective first male terminals 108 and the second contact portions 119 of the respective second male terminals 113 are both disposed in the third mounting cavity 124.

[0110] Specifically, the first contact portions 118 of the first male terminals 108 and the second contact portions 119 of the second male terminals 113 are placed in the third mounting cavity 124 of the first plugging portion 121. One end of the third mounting cavity 124 is an open structure. In this way, when the plug is docked with the socket, these contact portions can contact the contact portions of the corresponding female terminals in the socket and establish an electrical connection.

[0111] In the embodiment of the present application, by reasonably arranging the first mounting cavity 122, the second mounting cavity 123, and the third mounting cavity 124, the entire plug structure is compact, reducing space occupation and facilitating installation and use.

[0112] According to an embodiment of the present application, with reference to Figure 4 and Figure 8 as shown, each first wiring portion 109 of the respective first male terminals 108 is provided with a first ferrule 125. Each first ferrule 125 is snap-fitted into the first mounting cavity 122 one by one, and each first gasket 110 abuts against each first ferrule 125 one by one.

[0113] Specifically, the first ferrule 125 includes two half-spliced first sleeve bodies 126.

[0114] During assembly, the first male terminal 108 is assembled with the first ferrule 125, and then the first ferrule 125 is inserted into the first mounting cavity 122 from the first opening 105 until the first elastic piece 127 abuts against the first abutting wall 128, and then the first gasket 110 is abutted against the first ferrule 125.

[0115] According to an embodiment of the present application, with reference to Figure 5 and Figure 9As shown, a first pressure sleeve 129 is provided in the second installation cavity 123. The first pressure sleeve 129 is used to press-fit the second wiring portions 114 of the second male terminals 113 in the second installation cavity 123, and the second gasket 115 abuts against the first pressure sleeve 129.

[0116] Specifically, the peripheral wall of the first pressure sleeve 129 is recessed inward to form a plurality of first accommodation grooves 130 for respectively accommodating the second wiring portions 114 of the second male terminals 113 one by one. The second male terminal 113 further includes a first crimping portion 131, and the first crimping portion 131 is connected between the second wiring portion 114 and the second contact portion 119.

[0117] During assembly, the second wiring portion 114 of the second male terminal 113 is inserted into the first accommodation groove 130 of the first pressure sleeve 129, and the end face of the first pressure sleeve 129 is press-fitted onto the first crimping portion 131, and then the second gasket 115 is abutted against the first pressure sleeve 129.

The fourth installation cavity 132 is sealingly connected with a first anti-fooling post 133, and the first anti-fooling post 133 extends into the third installation cavity 124.

[0119] Specifically, the first anti-fooling post 133 is provided with a groove 134 extending along the axial direction to facilitate insertion with the protrusion 234 of the second anti-fooling post 233 on the socket, thereby preventing misinsertion.

[0120] Moreover, a first sealing ring 135 is provided between the first anti-fooling post 133 and the fourth installation cavity 132 to improve the sealing and waterproof performance.

[0121] According to an embodiment of the present application, referring to Figure 1 As shown, the first end cap 103 is snap-fitted with the first installation portion 120 of the plug body 100. Specifically, two first bayonet openings 136 are respectively provided on the opposite sides of the first end cap 103, and two first buckles 137 are respectively provided on the opposite sides of the first installation portion 120. The first buckles 137 are snap-fitted with the first bayonet openings 136 one by one. Designed in this way, the disassembly and assembly convenience of the plug can be improved.

[0122] According to an embodiment of the present application, referring to Figure 1 As shown, a handle 138 is connected to the first installation portion 120 of the plug body 100 to facilitate the user to lift and place, and improve the user experience.

[0123] According to an embodiment of the present application, referring to Figure 1As shown, a sealing ring 139 is provided on the outer wall of the first plugging portion 121 of the plug body 100. When the first plugging portion 121 of the plug body 100 is plugged into the second plugging portion 221 of the socket body 200, the connection sealing performance can be improved through the sealing ring 139.

[0124] Currently, most existing sockets are provided with an installation opening on the back side of the socket body to install the female terminal, and then the installation opening is covered by a cover plate. The sealing and waterproof performance of this assembly structure is relatively low, and there is a potential safety hazard of water ingress.

[0125] For this reason, according to the embodiment of the second aspect of the present application, with reference to Figures 11 - 17 As shown, the present application further provides a socket, including: a socket body 200, a female terminal 201, a second sealing structure 202, and a second end cover 203. Among them, the socket body 200 has a second end 204, and the second end 204 is provided with a second opening 205; the female terminal 201 is arranged inside the socket body 200, the female terminal 201 has a second wiring structure, and the second wiring structure faces the second opening 205; the second sealing structure 202 is arranged at the second opening 205, and the second sealing structure 202 is provided with a second wire pressing hole structure 206 corresponding to the second wiring structure of the female terminal 201; the second end cover 203 is connected to the second opening 205 and covers the second sealing structure 202, and the second end cover 203 is provided with a second wire passing hole structure 207 corresponding to and communicating with the second wire pressing hole structure 206.

[0126] In this embodiment of the present application, the socket body 200 is the carrier part of the whole device. It has a second end 204, and a second opening 205 is provided at this end, which is convenient for the installation of the female terminal 201.

[0127] The female terminal 201 is located inside the socket body 200 and has a second wiring structure facing the second opening 205. This design enables the wire to be connected to the second wiring structure of the female terminal 201 by accessing from the direction of the second opening 205.

[0128] The second sealing structure 202 is installed at the second opening 205, and it is provided with a second wire pressing hole structure 206 corresponding to the second wiring structure of the female terminal 201. This wire pressing hole structure can not only ensure that the wire is correctly connected to the second wiring structure of the female terminal 201, but also be tightly compressed when the wire passes through the wire pressing hole structure, thereby forming a good physical seal to prevent moisture intrusion and achieving the sealing effect.

[0129] The second end cover 203 is connected to and covers the second opening 205, and also covers the second sealing structure 202. It is also provided with a second wire passing hole structure 207, which is matched with the second wire pressing hole structure 206 on the second sealing structure 202 to ensure that the wire can pass through smoothly without affecting the sealing performance.

[0130] Therefore, the embodiments of the present application can effectively improve the sealing and waterproof performance of the socket, thereby enhancing safety and reliability, and facilitating assembly.

[0131] According to an embodiment of the present application, with reference to Figures 11 - 14 As shown, the female terminal 201 includes a pair of first female terminals 208, the second wiring structure includes a third wiring portion 209, and each first female terminal 208 has a third wiring portion 209; the second sealing structure 202 includes a pair of third sealing gaskets 210, the second wire pressing hole structure 206 includes a third wire pressing hole 211, each third sealing gasket 210 is hermetically sealed to the third wiring portion 209 of each first female terminal 208 one by one, and each third sealing gasket 210 is provided with a third wire pressing hole 211 corresponding to each third wiring portion 209; the second wire passing hole structure 207 of the second end cap 203 includes a pair of third wire passing holes 212, and each third wire passing hole 212 corresponds to each third wire pressing hole 211 one by one. It can be understood that the pair of first female terminals 208 are the positive and negative female terminals.

[0132] Specifically, the wire passes through the third wire passing hole 212 of the second end cap 203, then passes through the third wire pressing hole 211 on the third sealing gasket 210, and is electrically connected to the third wiring portion 209 of the first female terminal 208.

[0133] The design of the third wire pressing hole 211 can ensure that the wire is properly compressed when passing through, thereby forming a tight contact between the wire and the hole, reducing the possibility of moisture or other contaminants entering. The third sealing gasket 210 itself can be made of a waterproof material to further enhance the sealing effect. The use of the second end cap 203 not only provides additional physical protection, but also strengthens the sealing effect through the precise matching of the third wire passing hole 212 and the third wire pressing hole 211 thereon.

[0134] Due to the dual sealing measures of the third sealing gasket 210 and the second end cap 203, even in a harsh environment, it can effectively prevent moisture from entering the socket interior and protect the circuit from damage.

[0135] Therefore, through the above design, the embodiments of the present application effectively improve the sealing and waterproof performance of the socket, ensuring the stability and safety of the electrical connection.

[0136] According to an embodiment of the present application, with reference to Figures 11 - 13 and Figure 15As shown, the female terminal 201 further includes a plurality of second female terminals 213.

The second wiring structure further includes a fourth wiring portion 214, and each second female terminal 213 has a fourth wiring portion 214. The second sealing structure 202 further includes a fourth gasket 215, and the second wire pressing hole structure 206 further includes a fourth wire pressing hole 216. The fourth gasket 215 seals the fourth wiring portion 214 of each second female terminal 213, and the fourth gasket 215 is provided with a fourth wire pressing hole 216 corresponding to each fourth wiring portion 214. The second wire passing hole structure 207 of the second end cap 203 further includes a plurality of fourth wire passing holes 217, and each fourth wire passing hole 217 corresponds to each fourth wire pressing hole 216 one by one. In this example, the female terminal 201 may include four second female terminals 213, and the four second female terminals 213 are provided between a pair of first female terminals 208. Of course, the number of the second female terminals 213 may also be more, and can be specifically designed and adjusted according to actual requirements.

[0137] Specifically, the wire passes through the fourth wire passing hole 217 of the second end cap 203, then passes through the fourth wire pressing hole 216 on the fourth gasket 215, and is electrically connected to the fourth wiring portion 214 of the second female terminal 213.

[0138] By integrating the first female terminals 208 and the second female terminals 213, the socket of the present application enables the socket to support multiple types of current or signal transmission, increasing its scope of application and functionality.

[0139] The design of the fourth wire pressing hole 216 ensures that the wire is properly compressed when passing through, thereby forming a tight contact between the wire and the hole, reducing the possibility of moisture or other contaminants entering. The fourth gasket 215 can be made of a waterproof material to further enhance the sealing effect. The second end cap 203 not only provides additional physical protection, but also strengthens the sealing effect through the precise matching of the fourth wire passing holes 217 and the fourth wire pressing holes 216 thereon, and can effectively prevent moisture from entering the interior of the socket and protect the circuit from damage.

[0140] Therefore, through the above design, the embodiment of the present application can not only provide a plurality of female terminals for different uses, but also ensure the sealing and waterproof performance of all terminals, thereby ensuring the reliability and safety of the connector in various application environments.
