[0027] In the examples of this application, refer to Figure 1 、 Figure 2 and Figure 5 , including a socket 1, a plug 2, a socket mounting plate 3 and a plug mounting plate 4, the socket 1 is arranged on the socket mounting plate 3, and the plug 2 is arranged on the plug mounting plate 4.

[0028] Reference Figure 2The socket 1 includes a socket insulating mounting base 13, a jack contact 12 and a socket housing 11. The jack contact 12 is arranged on the socket insulating mounting base 13. The jack contact 12 is provided with a pin barb structure 32, which helps to firmly connect the jack contact 12 to the socket insulating mounting base 13; a connecting groove is provided on the side opposite to the socket insulating mounting base 13, and a rubber sealing layer 19 is provided in the connecting groove to achieve waterproof sealing of the interior of the socket 1 to prevent water leakage inside the socket 1;

[0029] A socket butt-joint end sealing ring 15 is sleeved on the outer peripheral side of the socket insulating mounting seat 13. The socket butt-joint end sealing ring 15 is made of rubber material and realizes a sealed connection when the socket 1 and the plug 2 are docked. The socket housing 11 is fixedly set on the outer peripheral side of the socket insulating mounting seat 13, and a first sealing member is set between the socket insulating mounting seat 13 and the socket mounting plate 3.

[0030] Reference Figure 2 The first sealing member is set as a first sealing ring 18, which is made of epoxy sealant. A first special-shaped groove 29 is commonly surrounded by the outside of the socket insulating mounting seat 13, the socket shell 11 and the socket mounting plate 3. The first sealing ring 18 is arranged in the first special-shaped groove 29, so that the first sealing ring 18 is not easy to fall off from the first special-shaped groove 29; the first sealing ring 18 and the first special-shaped groove 29 have an interference fit, so that the first sealing ring 18 fills and seals the gap between the socket insulating mounting seat 13, the socket shell 11 and the socket mounting plate 3, thereby avoiding water leakage between the socket 1 and the socket mounting plate 3 as much as possible.

[0031] Reference Figure 1 and Figure 2 At the same time, a groove 34 is opened on the socket shell 11, and a first sealing rubber ring 14 is arranged in the groove 34. The first sealing rubber ring 14 conflicts with the side of the socket mounting plate 3 to achieve a sealed connection between the socket shell 11 and the socket mounting plate 3, thereby enhancing the sealing between the socket shell 11 and the socket mounting plate 3.

[0032] In the examples of this application, refer to Figure 1 、 Figure 3 and Figure 4The plug 2 includes a plug insulating mounting seat 23, a pin contact 22 and a plug shell 21. The plug shell 21 is arranged on the outer peripheral side of the plug insulating mounting seat 23. The pin contact 22 is arranged on the plug insulating mounting seat 23 to facilitate docking with the jack contact 12 on the socket 1. The pin contact 22 is provided with a pin barb structure 31 to firmly connect the pin contact 22 to the plug insulating mounting seat 23. A mounting groove is provided on the back side of the plug insulating mounting seat 23. A rubber sealing layer 19 is also provided in the mounting groove, so that the interior of the plug 2 has a waterproof function. A second sealing member is provided between the plug insulating mounting seat 23 and the plug mounting plate 4.

[0033] Reference Figure 1 and Figure 3 The second sealing member is set as a second sealing ring 28, which is made of epoxy sealant material. A second special-shaped groove 30 is formed between the plug insulating mounting seat 23, the plug shell 21 and the plug mounting plate 4. The second sealing ring 28 is arranged in the second special-shaped groove 30, so that the second sealing ring 28 is not easy to fall off from the second special-shaped groove 30;

[0034] The second sealing ring 28 is interference fit with the second special-shaped groove 30, so that the second sealing ring 28 fills and seals the gap between the plug insulating mounting seat 23, the plug shell 21 and the plug mounting plate 4, thereby achieving a sealed connection between the plug 2 and the plug mounting plate 4, and further realizing a sealed and waterproof connection between the plug 2 and the plug mounting plate 4.

[0035] Reference Figure 1 and Figure 3 At the same time, a groove 34 is also provided on the plug housing 21, and a second sealing rubber ring 24 is provided in the groove 34. The second sealing rubber ring 24 is in conflict with the side surface of the plug mounting plate 4 to achieve a sealed connection between the plug housing 21 and the plug mounting plate 4, thereby enhancing the sealing between the plug housing 21 and the plug mounting plate 4.

[0036] In the examples of this application, refer to Figure 1 and Figure 3 The socket housing 11 and the plug housing 21 are both provided with a guide mechanism; the guide mechanism includes a socket guide pin 16, a socket guide sleeve 17, a plug guide pin 26 and a plug guide sleeve 27. The socket guide pin 16 and the socket guide sleeve 17 are fixed to the socket housing 11 by screws 5, and the plug guide pin 26 is also fixed to the plug housing 21 by screws 5;

[0037] A floating screw 25 is fixedly connected to the plug guide sleeve 27. A through-hole 33 is defined in the plug housing 21. The end of the floating screw 25, distal from the plug guide sleeve 27, passes through the through-hole 33 and connects to the plug mounting plate 4. The floating screw 25 has a clearance fit within the through-hole 33. The plug guide sleeve 27 is floatingly connected to the plug housing 21 via the floating screw 25. The plug guide sleeve 27 engages with the receptacle guide pin 16, and the plug guide pin 26 engages with the receptacle guide sleeve 17.

[0038] When the socket 1 and the plug 2 are mated, the plug guide sleeve 27 floats radially, allowing the plug guide sleeve 27 to quickly align with the socket guide pin 16. The socket guide sleeve 17 and the plug guide pin 26 are precisely mated, so that the socket contact 12 and the pin contact 22 can be mated more accurately, avoiding the phenomenon of the socket contact 12 and the pin contact 22 being inserted obliquely with each other, and minimizing the friction between the socket contact 12 and the pin contact 22, thereby helping to extend the service life of the connector;

[0039] At the same time, the socket guide sleeve 17 is aligned with the plug guide pin 26, and the plug guide sleeve 27 is aligned with the socket guide pin 16, so as to realize the guiding function of the docking between the plug 2 and the socket 1. When the socket 1 or the plug 2 is rotated, the socket guide sleeve 17 is no longer aligned with the plug guide pin 26, and the plug guide sleeve 27 is no longer aligned with the socket guide pin 16, so that the docking between the plug 2 and the socket 1 cannot be achieved. This structure avoids the phenomenon of reverse insertion of the jack contact 12 and the pin contact 22, thereby avoiding signal transmission errors, which helps to protect the connector.

[0040] The working principle of this embodiment is as follows: when the plug 2 is docked with the socket 1, the socket guide sleeve 17 is used to guide the plug guide pin 26, and the plug guide sleeve 27 is used to guide the socket guide pin 16, so that the plug 2 and the socket 1 can be accurately docked, avoiding excessive wear of the plug 2 and the socket 1 during the docking process, and ensuring the smooth circuit of the connector; when the plug 2 and the socket 1 are connected, the first sealing ring 18 is used to seal between the socket 1 and the socket mounting plate 3, so that the socket 1 and the socket mounting plate 3 have a waterproof effect, and then the second sealing ring 28 is used to seal between the plug 2 and the plug mounting plate 4, so that the plug 2 and the plug mounting plate 4 have a waterproof function, and the first sealing rubber ring 14 and the second sealing rubber ring 24 respectively enhance the sealing and waterproof properties of the socket 1 and the plug 2 themselves, so as to achieve comprehensive sealing when the plug 2 and the socket 1 are connected, so that the entire connector has good sealing and waterproof properties, thereby ensuring the conductive performance of the connector.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
