It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0033] Embodiment 1:

[0034] like Figure 1-5 As shown, a new type of curved single-core connector with snap-on quick locking includes: a plug assembly and a socket assembly that cooperate with each other;

[0035] The plug assembly includes: a shielding ring spring 1, a plug sealing ring 2, a signal jack 3, a front insulator 4, a jack assembly 5, a hook 6, a pin 7, a torsion spring 8, a compression spring 9, a button 10, a plug housing 11, a rear insulator 12, a self-locking nut 13, a welding terminal 14, a shielding outer sleeve 15, a shielding inner sleeve 16, a baffle 17, a sealing body 18, a tail cover 19, and a piercing rib 30; a snap-on hanging platform 31;

[0036] The socket assembly includes: a socket housing 20, a pin clamp ring 21, a socket insulator 22, a pin 23, a rivet nut 24, a signal pin 25, a pin signal sheath 26, a socket sealing ring 27, a reverse buckle 28, and a hanging platform 29.

[0037] The front end of the plug housing 11 is equipped with a sealing ring 2 through a rubber encapsulation process. The sealing ring 2 has 2-6 lips (colors: blue, green, white, black) and is used for waterproof sealing when the plug assembly and the socket housing 20 are mated. Figure 1 , and a shielding ring spring 1 is also provided for shielding signal conduction between the plug housing 11 and the socket housing 20.

[0038] The rear side wall of the plug housing 11 contacts the shielding jacket 15, and the shielding jacket 15 is connected to the shielding inner jacket 16, so that the shielding chain at the plug end is connected. Figure 1 ;

[0039] The jack assembly 5 and the welding terminal 14 are connected by a threaded connection between the built-in bolt of the jack assembly 5 and the self-locking nut 13 fixed in the insulator 12 behind the hole to realize the 90° transfer of the power terminal in the plug, and prevent the jack assembly 5 and the welding terminal 14 from being withdrawn. Figure 1 ;

[0040] The rear end of the plug housing 11 is sequentially loaded with a baffle 17, a sealing body 18, and a tail cover 19. The baffle 17 is blocked by the shielding jacket 15 to prevent it from being pushed forward, and the tail cover 19 is buckled with the plug housing 11 to prevent it from being withdrawn. Figure 1 .

[0041] The bottom of the socket housing 20 is provided with a socket sealing ring 27. The socket sealing ring 27 can be selected with 2-6 lips (color: blue, green, white, black) according to the installation size, which is used for waterproof sealing when the socket assembly and the mounting plate end are mated. Figure 1 .

[0042] The hook 6 is mounted on the plug housing 11 through the pin 7 and the torsion spring 8 to form a lever structure; after the plug housing 11 and the socket housing 20 are inserted into place, the hook 6 is used to cooperate with the hanging platform 29 on the socket housing 20 to fix it. Figure 1 , to achieve quick locking, and the compression spring 9 installed inside the button 10 rebounds and drives the button 10 back to the initial position to prevent accidental unlocking of the head seat due to accidental touch. When unlocking, just press the button 10 and push it down to unplug the plug.

[0043] The jack assembly 5 is installed in the front hole insulator 4 and pre-fixed by the piercing rib 30 through interference fit, and then the front hole insulator 4 is installed in the plug housing 11 and fixed with the rear hole insulator 12 that is interference fitted in the plug housing 11 through the snap hanger 31. Figure 1 , making the plug structure more solid and more resistant to vibration.

[0044] The pin is inserted into the socket insulator 22 and is limited by the pin collar 21 to prevent the pin from being withdrawn. Then, the socket insulator 22 is inserted into the socket housing 20 and is limited by the reverse buckle 28. Figure 1 .

[0045] The plug housing 11 and the socket housing 20 achieve 360° shielding conduction through the flexible contact of the shielding ring spring 1, and the vibration resistance is stronger. Figure 1 .

[0046] The signal jack 3 is inserted into the insulator 4 before the hole is limited by the tooth sleeves on both sides. Figure 2 .

[0047] The signal pin 25 is installed into the pin signal sheath 26, and then the pin signal sheath 26 is installed into the socket insulator 22 to complete the assembly. At the same time, the buckles on both sides of the pin signal sheath 26 are squeezed and tilted inward to clamp the tooth sleeve of the signal pin 25 to prevent the pin from retreating. This structure realizes the modularization and platformization of signal components, and is also convenient for customers to assemble. Figure 3 .

[0048] The socket housing 17 is fixed to the mounting plate end by 2-10 plate end screw assemblies 16. Figure 3 The board end screw assembly 16 can be a screw assembly with a plug housing and a post-installed screw assembly. The locking mechanism is stable and reliable. Figure 3 .

[0049] A rivet nut 24 is riveted onto the pin 23 for bolt connection with a counterpart.

[0050] By selecting different surface treatments for the metal shell, such as passivation, nickel plating, zinc-nickel alloy plating, etc., the overall metal connector can withstand salt spray for 36-1200 hours.

[0051] The single-core connector of the present application consists of a bent plug assembly and a straight socket assembly. The cable is installed in the plug, and a waterproof seal is achieved between the cable and the plug shell by a wire sealing body. At the same time, the shielding conduction between the cable shielding layer and the plug shell is achieved by a shielding jacket crimped on the cable. At the same time, the shielding conduction of the head seat is achieved through the flexible contact between the shielding ring spring and the socket shell; the front end of the cable is connected to the welding terminal by ultrasonic welding, and the signal pin and the signal jack are inserted into place to realize the transmission of signal current. After that, the power current passes through the welding terminal to the jack assembly bolted to it, and then flows to the pin in contact with it through the jack assembly, so as to realize the power current transmission between the head seats.

[0052] The connectors on the market are generally based on plastic shells. In order to achieve shielding conduction, other shielding parts need to be added inside the connector. The shell of the present invention is wrapped with metal, plastic and synthetic materials, and can directly achieve 360° shielding through the connection of the outer metal shell. Compared with the existing curved plugs with plastic shells, other shielding parts for shielding connection are reduced inside.

[0053] The plug and socket are fixed by snap-on quick locking, which is similar to the most common pull-rod connector currently. This reduces the space for pulling the pull rod and further reduces the assembly space of the vehicle.

[0054] Moreover, this quick-locking structure intersects with the existing connector that fixes the headstock by bolt connection, making installation easier and faster, and reducing assembly time;

[0055] The sealing ring on the plug adopts the rubber coating process, which avoids the risk of the existing connector using assembled sealing rings that easily tip over during the plug-in process;

[0056] The high-current and high-voltage connectors on the market are relatively large in size, while the connector of the present invention has a small overall size and a more compact structure, which is easy to arrange in the space of the vehicle; the present invention can realize the output of wires in multiple directions according to the cooperation of different key positions.

[0057] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
