[0030] See also Figure 1-7 As shown, an embodiment of the utility model provides a plug and a connector assembly, wherein the connector assembly includes a socket 3 and the plug, and the plug and the socket 3 are adapted to be connected to achieve electrical connection and / or signal transmission.

[0031] The plug includes: the plug body 1 and an exhaust assembly 2 disposed in the plug body 1. An exhaust groove 11 communicating with the outside is disposed in the plug body 1, and the exhaust assembly 2 is located in the exhaust groove 11 and is used to control the opening and closing of the exhaust groove 11. By controlling the opening and closing of the exhaust groove 11, air pressure balance is achieved, thereby ensuring the sealing of the connector and preventing the air inside the plug from being squeezed but unable to be discharged, causing trapped air and making it difficult to insert the connector.

[0032] The exhaust assembly 2 includes a piston 21 movably arranged in the exhaust groove 11 and an elastic member 22 arranged between the piston 21 and the bottom end of the exhaust groove 11. The piston 21 has a first position and a second position. In the first position, the piston 21 closes the exhaust groove 11 to disconnect the exhaust groove 11 from the outside. In the second position, the piston 21 opens the exhaust groove 11 to connect the exhaust groove 11 to the outside. When the plug is docked with the socket 3, the internal space of the plug body 1 is reduced, and the air pressure increases to press the piston 21 to move to the second position. After the air pressure inside and outside the plug is balanced, the elastic force of the elastic member 22 drives the piston 21 to move to the first position.

[0033] In the utility model, an exhaust groove 11 connected to the outside is provided in the plug body 1, and a piston 21 of the exhaust assembly 2 is movably provided in the exhaust groove 11, and the piston 21 has a first position and a second position in the exhaust groove 11. When the piston 21 is in the first position, the piston 21 can close the exhaust groove 11, thereby disconnecting the exhaust groove 11 from the outside. When the piston 21 is in the second position, the piston 21 can open the exhaust groove 11, thereby connecting the exhaust groove 11 to the outside. The elastic member 22 is provided between the piston 21 and the bottom end of the exhaust groove 11, so that the piston 21 can Switch from the second position to the first position; specifically, when the plug body 1 is sealed and docked to the socket 3, the air pressure space inside the plug body 1 decreases, and the air pressure increases to press the piston 21 so that the piston 21 moves to the second position, the exhaust groove 11 is opened, and the exhaust groove 11 is connected to the outside world, and part of the air pressure inside the plug body 1 is discharged to the outside world through the exhaust groove 11. When the air pressure inside and outside the plug body 1 is balanced, the elastic force of the elastic member 22 drives the piston 21 to move to the first position, the exhaust groove 11 is closed, and the exhaust groove 11 is disconnected from the outside world, thereby sealing the inside of the plug body 1. The use of this technical solution can realize air pressure discharge on the basis of ensuring the plug is closed, solving the technical problem that the air inside the connector cannot be discharged due to compression, which causes trapped air and makes it difficult to insert the connector.

[0034] In some specific embodiments, see Figure 2 There are two exhaust grooves 11 and two exhaust components 2. The two exhaust grooves 11 are respectively arranged at opposite ends of the plug body 1, and the two exhaust components 2 are respectively arranged in the two exhaust grooves 11.

[0035] The piston 21 and the elastic member 22 in the exhaust assembly 2 are exquisitely designed, and can react quickly and exhaust gas in time when the external air pressure changes, thereby avoiding excessive air pressure inside the connector and damaging the connector. In addition, the connector has a simple structure, is easy to manufacture and maintain, has high reliability, and is suitable for sealing connections in various occasions and environments.

[0036] In some specific embodiments, the elastic member 22 is configured as a spring.

[0037] In one embodiment, see Figure 2 and Figure 3 The plug body 1 includes a main housing 12, a first sealing member 13, and a cover shell 14. The first sealing member 13 is installed on the main housing 12, and the main housing 12 is connected to the cover shell 14, and the cover shell 14 is used to fix the first sealing member 13 on the main housing 12. The first sealing member 13 installed between the main housing 12 and the cover shell 14 can effectively improve the sealing between the main housing 12 and the cover shell 14, thereby maintaining the sealing of the plug.

[0038] See also Figure 5 The cover shell 14 is provided with a cover shell through hole 141, and the cover shell through hole 141 is used for the cable to pass through, thereby realizing the electrical connection function of the plug.

The piston 21 is used to open or close the second exhaust hole 112 so as to connect or disconnect the second exhaust hole 112 with the exhaust chamber 113. On the one hand, it is convenient to install the exhaust assembly 2 relative to the exhaust groove 11. On the other hand, the piston 21 closes and opens the second exhaust hole 112 to realize the closing and opening of the exhaust groove 11 by the piston 21, which can improve the sealing performance of the piston 21 for closing the exhaust groove 11 and improve the sealing performance of the plug body 1.

[0040] Specifically, the elastic member 22 is disposed between the piston 21 and the bottom of the exhaust chamber 113 , so as to drive the piston 21 to move to the first position to close the communication between the first exhaust hole 111 and the exhaust chamber 113 .

[0045] In some specific embodiments, see Figure 4 The main shell 12 is also formed with a docking portion 1231 located at the docking end 123. The docking portion 1231 is used to be inserted into the socket 3. The docking portion 1231 plays a guiding role when the plug is docked to the socket 3, thereby improving the docking compatibility between the plug and the socket 3.

[0046] In some specific embodiments, see Figure 4 The docking portion 1231 encloses a docking cavity 1232, and the plug further includes a terminal lock 16 disposed in the docking cavity 1232, and a docking hole 161 is provided in the terminal lock 16, the docking hole 161 is communicated with the docking cavity 1232, and the docking hole 161 corresponds to the mounting hole 1211. The wiring terminals are arranged in the docking holes 161 of the terminal lock 16 in a one-to-one correspondence, and the terminal lock 16 is arranged in the docking cavity 1232 to limit each wiring terminal, thereby improving the stability of the plug and the socket 3 when docking.

[0047] In one embodiment, see Figure 3 and Figure 6The plug further includes a second sealing member 15 sleeved on the docking portion 1231, and the second sealing member 15 is used to play a sealing role during the plugging process of the main housing 12. Specifically, when the plug is docked to the socket 3, the second sealing member 15 is clamped between the outer peripheral wall of the docking portion 1231 and the inner peripheral wall of the socket 3, so as to achieve sealed docking between the plug and the socket 3.

[0048] In some specific embodiments, see Figure 4 and Figure 5 A cover buckle 143 is formed on the outer wall of the cover shell 14 , and a slot 124 matching with the cover buckle 143 is also provided on the main shell 12 , thereby realizing the connection between the cover shell 14 and the main shell 12 .

[0049] In a specific embodiment, see Figure 7 The first sealing member 13 is further provided with a limiting groove 131 arranged around the second exhaust hole 112, the limiting groove 131 is communicated with the exhaust chamber 113, and the limiting groove 131 is used to limit the piston 21. The limiting groove 131 limits the position of the piston 21 relative to the second exhaust hole 112 to ensure that the piston 21 can close the second exhaust hole 112, thereby improving the sealing and smoothness of the piston 21 in closing the second exhaust hole 112.

[0050] In a specific embodiment, see Figure 7 The piston 21 includes a covering portion 211 and a first guide portion 212. The covering portion 211 is located in the limiting groove 131, and the first guide portion 212 is connected to the covering portion 211, and the first guide portion 212 is located in the first exhaust hole 111.
