However, during use, dust, moisture, or other foreign matter in the environment can contaminate the inside of the connector, affecting the stability of the circuit connection. Furthermore, connectors can detach due to external forces or vibrations during connection, which can lead to equipment malfunctions and even compromise safety in severe cases.

[0003] Traditional connector designs often lack effective protective and locking structures, especially in outdoor or complex working environments, failing to adequately prevent foreign object ingress or ensure connection stability. For example, some connectors, while featuring simple dust covers, lack the function of securing them to the connector body, making them prone to loss. Furthermore, many existing connectors lack effective locking mechanisms, making them susceptible to detachment under vibration or external force, increasing the risk of misuse. Some connectors also have insufficient power, rendering them inoperable. Therefore, developing a connector that effectively prevents foreign object ingress and possesses a reliable locking function is of great significance. Utility Model Content

[0027] Rotary snap connector, please refer to Figure 1-4 The device includes a socket 100, a plug 200, and a rotating buckle 300. The socket 100 includes a socket housing 110 and a dust cover 120 connected to the socket housing 110. The socket housing 110 has a connecting cavity 120 with one open end, which extends outward and forms a wall. The dust cover 120 can be closed and fastened to the connecting cavity 120, preventing the socket 100 from closing the connecting cavity 120 when the plug 200 is not connected, thus preventing water or dust from entering the connecting cavity 120 and improving the service life of the socket 100. The socket housing 110 has outwardly protruding locking protrusions 130 on both sides. The plug 200 includes a plug housing 210 and an outer housing 220 connected to the plug housing 210. The plug housing 210 has an insertion end 230 that can be connected to the connecting cavity 120. The insertion end 230 is smaller than the connecting cavity 120, and the plug 200 can be inserted into the connecting cavity 120 through the insertion end 230 to connect to the socket 100, facilitating the connection between the two. The rotating buckle 300 is flipped and mounted on the outer shell 220. The rotating buckle 300 has locking grooves 310 on both sides for locking protrusions 130 to be connected. The plug 200 locks the locking protrusions 130 through the rotating buckle 300, which can ensure that the plug 200 will not come off when connected to the socket 100, improve the connection stability, and prevent the plug 200 and the socket 100 from separating due to external forces such as vibration.

[0028] Furthermore, the socket 200 has fixing protrusions 221 on both sides, which can be integrally formed on the socket housing 210 or the outer shell 220. The rotating buckle 300 has connecting holes 320 on both sides that match the fixing protrusions 221. The rotating buckle 300 engages with the fixing protrusions 221 through the connecting holes 320 to achieve a flip-out connection to the socket 200. The fixing protrusions 221 are cylindrical structures with protruding structures extending from their edges. The shape of the connecting holes 320 matches the fixing protrusions 221 and their protruding structures. The rotating buckle 300 aligns with the fixing protrusions 221 through the connecting holes 320 and is inserted. After being inserted, it is rotated and its protruding structure forms a locking position with the connecting holes 320 to prevent the rotating buckle 300 from falling off the outer shell 220.

[0029] Furthermore, one side of the rotating buckle 300 is provided with a slot 311 connecting to the end of the locking groove 310. The locking protrusion 130 can be inserted into or disengaged from the locking groove 310 through the slot 311. The locking groove 310 has an arc-shaped structure to match the flipping direction of the rotating buckle 300. The locking protrusion 130 has a structure that is larger at the top and smaller at the bottom. The smaller part of the locking protrusion 130 is inserted into the locking groove 310, while the larger part at the top is stuck in the locking groove 310 and cannot be disengaged, ensuring the locked state. When the rotating buckle 300 is flipped to a horizontal position... When the slot 311 reaches the side of the locking protrusion 130, the plug 200 can be easily pulled out horizontally after unlocking. Conversely, when the plug 200 needs to be connected to the socket 100, the rotating buckle 300 needs to be flipped open, the plug 200 is inserted into the socket 100, and the slot 311 is aligned with the locking protrusion 130 so that it can be inserted into the locking slot 310. After the locking protrusion 130 is inserted into the locking slot 310, the rotating buckle 300 is flipped down, and the locking protrusion 130 and the rotating buckle 300 form a latching state, thus completing the locking connection between the socket 100 and the plug 200.

[0030] Furthermore, a locking hook 222 is provided on the side of the outer casing 220 away from the socket 100. The locking hook 222 is a hook-shaped structure protruding from the surface of the outer casing 220. A locking button 330 that can move elastically is provided at the end of the rotating buckle 300. The locking button 330 is snapped and fixed on the rotating buckle 300. A spring is provided between the locking button 330 and the rotating buckle 300. The user can move the locking button 330 up and down. The inner side of the locking button 330 is provided with a latching protrusion structure that matches the locking hook 222. When the rotating buckle 300 is flipped down, the latching protrusion structure of the locking button 330 can be inserted into the locking hook 222 to form a latch lock. The spring push keeps the locking button 330 in a downward push, keeping the rotating buckle 300 in the flipped state and preventing the rotating buckle from flipping up when the user touches the plug 200. When the user needs to disconnect the plug 200 from the socket 100, he can push the locking button 330 up to unlock it from the locking hook 222 and flip the rotating buckle 300.

[0031] Furthermore, the housing 220 is provided with a downwardly extending grip handle 223. The horizontal cross-section of the grip handle 223 is a flat shape. The extended handle 223 increases the area that the user can contact with the housing 220. The flat structure makes it easy for the user to grip the housing 220 and unplug the plug 200. One end of the dust cover 120 is connected to the socket housing 110, and the other end is provided with a cover body 161 that matches the connecting cavity 120. The cover body 161 has a protruding structure that matches the shape of the inner side of the connecting cavity 120. The cover body 161 is embedded in the connecting cavity 120 through the protruding structure to close the connecting cavity 120. A flexible connecting part 162 is provided between the two ends of the dust cover 120. The dust cover 120 is made of soft silicone material, so that the middle section can be bent. When the socket 100 needs to cover the dust cover 120, it is easy to flip it over. When the cover body 161 is opened, the dust cover 120 can still be connected to the socket 100 to prevent it from falling off or being lost, which is convenient for users.

[0032] Furthermore, the socket housing 100 contains multiple female hardware 140s, and the plug housing 210 contains multiple male hardware 240s that match the female hardware 140s. When the socket 100 and plug 200 are connected, the female hardware 140s and male hardware 240s are connected simultaneously to achieve circuit connection. The socket 100 is provided with a first cable 150 connecting the female hardware 140s, and the plug 200 is provided with a second cable 250 connecting the male hardware 240s. The two cables serve as extensions of the circuit to facilitate the connection of different devices or cables via connectors. The plurality of female hardware 140 includes two large female hardware 141, five small female hardware 142, and one medium female hardware 143. The plurality of male hardware 240 includes two large male hardware 241 that match the large female hardware 141, five small male hardware 242 that match the small female hardware 142, and one medium male hardware 243 that matches the medium female hardware 143. The number of female hardware 140 and male hardware 240 is not limited to this embodiment. The first cable 150 connects the two large male hardware 141, and the second cable 250 connects the two large female hardware 141, but the connection method is not limited to this embodiment. The cavity 120 is provided with mounting grooves that match each female hardware 140, and the insertion end 230 is provided with mounting grooves that match each male hardware 240. The mounting grooves in the cavity 120 and the insertion end 230 match each other to facilitate alignment and connection, and simultaneously realize the connection of the female hardware 140 and the male hardware 240. The large hardware connection allows the connector to receive 250A current. In other embodiments, it can receive currents of 250A or less. The small hardware 142 is used for signal transmission, and the medium hardware is used to connect the ground wire, realizing the integration of power, grounding and signal transmission, and reducing the complexity of wiring. The front end of the large female hardware 141 is provided with an anti-contact cap 244, which is sleeved on the front end of the large female hardware 141. The front end of the large female hardware 141 has a structure that cooperates with the anti-contact cap 144, so that the anti-contact cap 144 can be stably connected to the large female hardware 141. The anti-contact cap can effectively isolate the exposed part of the front end of the large female hardware, prevent the human body or other conductive objects from contacting the live parts, and reduce the risk of electric shock. Especially in high-voltage connectors or industrial equipment, this design can ensure the safety of operators.
