Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figures 1 to 4 As shown, this application provides a socket connector, including a housing assembly 10 and a conductive component 20. The conductive component 20 is disposed within the housing assembly 10 and at least partially exposed from the housing assembly 10 for connection with an external plug or cable.

[0030] In an optional embodiment, the conductive component 20 includes a first conductive element 21, a second conductive element 22, and a third conductive element 23. The second conductive element 22 and the third conductive element 23 are built into the housing component 10 and at least partially exposed from one or both sides of the housing component 10 to meet the requirements of side-out wiring, thereby ensuring the reliability of the electrical connection and providing mechanical support through the housing component 10.

[0031] For example, the first conductive element 21 is provided with a first wiring hole, the second conductive element 22 is provided with a second wiring hole, and the third conductive element 23 is provided with a third wiring hole. The housing assembly 10 has a first side and a second side opposite to each other. The first wiring hole and the third wiring hole are exposed from the first side and extend in a direction perpendicular to the first side. The second wiring hole is exposed from the second side and extends in a direction perpendicular to the second side. The first wiring hole and the third wiring hole are spaced apart so that the conductive cable can be fixed to the first wiring hole, the second wiring hole and the third wiring hole, so as to realize the electrical connection between the first conductive element 21, the second conductive element 22 and the third conductive element 23 and the outside. While ensuring the stability of its signal transmission, it also greatly reduces the cost.

[0032] In an optional embodiment, the housing assembly 10 has a relatively front side. A first conductive element 21 is mounted on the front side of the housing assembly 10 and has a mounting gap between it and the second conductive element 22 and the third conductive element 23. A protective door 30 is installed in the mounting gap to achieve a compact structure. The protective door 30 is used to open or close the socket structure 111 on the housing assembly 10 so that the second conductive terminal 221 of the second conductive element 22 and the third conductive terminal 231 of the third conductive element 23 can be electrically connected to the plug inserted into the socket structure 111. The first conductive element 21 can serve as a data identification contact, such as a USB PD protocol trigger, and can cooperate with the protective door 30 to ensure the reliability of the plug-socket connector connection, suitable for socket connectors with high safety requirements. At least part of the protective door 30 is hidden below the first conductive element 21, thereby preventing the user from touching the exposed protective door 30 and causing it to shift, thereby opening the socket structure 111 and causing a safety problem.

[0033] After adopting the above technical solution, since the first conductive element 21 is independently set on the front of the housing assembly 10, there is an installation gap between it and the second conductive element 22 and the third conductive element 23 to form a non-contact layout, thereby enabling it to undertake grounding or signal transmission functions. The second conductive terminal 221 of the second conductive element 22 and the third conductive terminal 231 of the third conductive element 23 can form two pins of the socket connector, namely the live wire pin and the neutral wire pin, so that after the plug is inserted into the socket structure 111, the first conductive element 21 contacts the periphery or outer side of the plug, avoiding direct contact between the human body and the second conductive terminal 221 of the second conductive element 22 and the third conductive terminal 231 of the third conductive element 23, reducing the threat to personal safety. The structure is simple, the operation is convenient, and it is safer and more reliable. The first conductive element 21 can also be used for signal transmission. It can generate a positioning signal after the plug is inserted into the socket structure 111. It establishes an electrical connection with the plug after ensuring that the plug is inserted in place, eliminating the risk of sparks when the plug contacts the second conductive element 22 and the third conductive element 23. This improves the stability and safety of the socket connector, reduces the threat to personal safety, and is simple in structure, easy to operate, and safer and more reliable.

[0034] In an optional embodiment, the first conductive element 21 includes a first clip 211, a second clip 212, and a first connecting piece 213. The first clip 211 and the second clip 212 are disposed at both ends of the first connecting piece 213 to form a symmetrical clamping structure. The second conductive terminal 221 and the third conductive terminal 231 are symmetrically disposed on both sides of the first connecting piece 213 for connecting to the connecting end disposed on the periphery of the plug. That is, the distance between the first clip 211 and the second clip 212 is adapted to the outer diameter of the plug. This enables electrical connection between the first clip 211 and the second clip 212 and the plug, and also securely fixes the plug in the connector with the socket. The structure is simple, reliable, has good contact, is easy to install, and has low manufacturing cost. It is suitable for use in various sockets. Through the special configuration of the first conductive element 21, space utilization is maximized and safety performance is enhanced.

[0035] In an optional embodiment, the first clip 211 has a first arc-shaped portion recessed towards the side of the second clip 212, and the second clip 212 has a second arc-shaped portion recessed towards the side of the first connecting piece 213. The first arc-shaped portion and the second arc-shaped portion engage with the two connecting ends on the plug, so that the plug can be securely connected to the connector with the socket. At the same time, the structural design of the first arc-shaped portion and the second arc-shaped portion can also facilitate the insertion and fixation of the plug. Through the innovative configuration of the double arc-shaped portion, the insertion and removal feel is optimized, and the reliability of the contact is improved. That is, the contact point changes from a single point to a double-line contact.

[0036] In an optional embodiment, the housing assembly 10 includes a first housing 11 and a second housing 12, which are interlocked to form a mounting cavity. A second conductive terminal 221 and a third conductive terminal 231 are housed in the mounting cavity. A socket structure 111 is formed on the first housing 11 and communicates with the mounting cavity, so that the housing assembly 10 can provide mechanical support and electrical isolation for the second conductive terminal 221 and the third conductive terminal 231, achieving a balance between high safety and easy maintenance of the socket connector.

[0037] For example, the first housing 11 and the second housing 12 can be directly fixed by means of snaps, screws or ultrasonic welding to form a mounting cavity for accommodating the second conductive terminal 221 and the third conductive terminal 231, thereby providing mechanical support and electrical isolation for the second conductive terminal 221 and the third conductive terminal 231.

[0038] In an optional embodiment, the first housing 11 is provided with a slot structure, and the second housing 12 is provided with a snap-fit ​​structure 121. The snap-fit ​​structure 121 engages with the slot structure to achieve a fixed connection between the first housing 11 and the second housing 12, simplifying the assembly line operation of the housing assembly 10 during the assembly process.

[0039] In an optional embodiment, the first housing 11 is provided with a rotating shaft 114, and the protective door 30 has a first blocking part, a second blocking part and a rotating hole 31. The protective door 30 is rotatably mounted on the rotating shaft 114 through the rotating hole 31. The first blocking part and the second blocking part are used to open or close the socket structure 111.

[0040] For example, the socket structure 111 includes a first socket and a second socket. The position of the second conductive terminal 221 corresponds to the position of the first socket, and the position of the third conductive terminal 231 corresponds to the position of the second socket. When the two pins of the plug are inserted into the first socket and the second socket, the two pins abut against the inclined or arc-shaped surfaces on the first and second shielding parts, causing the protective door 30 to rotate around the rotation axis 114, thereby exposing the socket structure 111. This allows one pin to pass through the first socket and connect electrically to the second conductive terminal 221, and the other pin to pass through the second socket and connect electrically to the third conductive terminal 231. The rotational physical movement of the protective door 30 effectively improves its durability and safety, making it suitable for socket products used in high-frequency plugging / unplugging or harsh environments.

[0041] In an optional embodiment, a Z-shaped movable space 112 is formed on the first housing 11, a socket structure 111 is formed at the bottom of the movable space 112, a protective door 30 is movably installed in the movable space 112, and a first conductive element 21 is installed at the upper end of the movable space 112, which can provide elasticity for the connection between the plug and the socket connector, so that the plug is firmly fixed on the socket connector; at the same time, the Z-shaped movable space 112 can also restrict the movement direction of the protective door 30, so that the protective door 30 can only rotate to one side.

[0042] In an optional embodiment, the minimum distance between the first conductive element 21 and the bottom of the movable space 112 is between 4mm and 5mm. This absorbs the injection molding tolerances and assembly errors of the first housing 11, preventing functional failures during mass production. It also ensures that the protective door 30 can move within the movable space 112, and meets the electrical clearance requirements within 380V, thereby maximizing safety and reliability while minimizing the size of the socket connector. The injection molding tolerance is ±0.3mm.

[0043] In an optional embodiment, the second conductive element 22 includes a second connecting piece 222 and a plurality of second conductive terminals 221 for plugs. The plurality of second conductive terminals 221 are spaced apart along the length direction of the second connecting piece 222. The positions of the second conductive terminals 221 correspond to one of the socket structures 111 in the active space 112 to support multiple plugs to be connected to the socket connector simultaneously.

[0044] In an optional embodiment, the third conductive element 23 includes a third connecting piece 232 and a plurality of third conductive terminals 231 for the plug. The plurality of third conductive terminals 231 are spaced apart along the length of the third connecting piece 232. The third conductive terminals 231 correspond to the position of one of the socket structures 111 in the active space 112 to support multiple plugs simultaneously with the socket connector.

[0045] In an optional embodiment, the first housing 11 is further provided with a receiving groove 113, and the second conductive terminal 221 and the third conductive terminal 231 are installed in the receiving groove 113.

[0046] In an optional embodiment, a reset spring is provided between the protective door 30 and the first housing 11. The reset spring is used to reset the protective door 30 without the action of external force. When the plug is inserted, the spring is gradually compressed to store energy. When it is pulled out, the energy is precisely released to drive the protective door 30 to return along the original path, thereby improving the automatic reset capability and reliability of the protective door 30.
