[0052] In existing technologies, traditional integrated connectors, due to the pre-attached socket housing and cable, often have a bulky and irregularly shaped overall structure. When installing them into automobiles or related equipment, operators must simultaneously manipulate the large wiring harness and housing, aligning and securing screws or clips, resulting in limited operating space and significant inconvenience. This severely reduces the overall assembly efficiency of the final product and makes it difficult to meet the demands of modern assembly lines for efficient and rapid operations.

[0053] This utility model proposes a direct-insertion high-voltage connector.

[0054] Please see Figures 1 to 12In one embodiment of this utility model, the direct-insertion high-voltage connector includes a socket assembly 10, which includes a socket housing assembly and a socket wiring harness assembly that are plugged into each other. The socket housing assembly includes a socket panel 100 and a socket shield 200. The socket panel 100 is used to install on an external device. The socket panel 100 has a panel cavity and a first panel slot 110 communicating with the panel cavity. The socket shield 200 is disposed in the panel cavity and has a socket shield cavity. The socket panel 100 has a first panel end face 120. The socket wiring harness assembly includes a socket inner liner 300 and a socket terminal 400. The socket terminal 400 is inserted into the inside of the socket inner liner 300. The socket inner liner 300 is inserted into the socket shield cavity. The outer wall of the socket inner liner 300 has an inner liner end face 310 and a cantilever boss 320. The inner liner end face 310 contacts the first panel end face 120, and the cantilever boss 320 is engaged in the first panel slot 110.

[0055] It should be noted that the socket assembly 10 is used for installation on external devices, such as automobiles. Understandably, after installation, the socket assembly 10 is compatible with the plug assembly 20 to enable power and signal transmission. In this embodiment, the socket assembly 10 includes a socket housing assembly and a socket wiring harness assembly. The socket housing assembly does not include the wiring harness; it is first installed on the external device so that the wiring harness does not interfere with the installation of the socket housing assembly, making installation convenient. Then, the socket wiring harness assembly is plugged into the socket housing assembly, thereby completing the installation of the entire socket assembly 10. This facilitates installation and improves installation efficiency.

[0056] refer to Figures 1 to 3 As shown, in a specific implementation, the socket housing assembly includes a socket panel 100 and a socket shield 200. The socket panel 100 is fixed to an external device by bolts or other connectors. The socket panel 100 also forms a panel cavity for mounting the socket shield 200. The socket shield 200 is made of metal and surrounds a socket shield cavity for connecting the socket wiring harness assembly, used to prevent electromagnetic and electrostatic interference to ensure the stability and safety of signal transmission. The socket shield 200 can be installed in the panel cavity by snap-fit ​​or interference fit to ensure that the socket shield 200 is effectively fixed in the panel cavity. In addition, the panel cavity has an inwardly extending protrusion with a first panel end face 120 to restrict the movement of the socket wiring harness assembly. A first panel slot 110 is provided on the side wall of the panel cavity.

[0057] The socket inner liner 300 of the socket harness assembly has a cavity for inserting the socket terminal 400. The socket terminal 400 is fixedly inserted into the interior of the socket inner liner 300, and the socket inner liner 300 is inserted into the socket shielding cavity of the socket shield 200, thereby realizing the assembly of the socket assembly 10. Furthermore, the outer wall of the socket inner liner 300 has an inner liner end face 310 and a cantilever boss 320. When the inner liner end face 310 is attached to the first panel end face 120, the cantilever boss 320 of the socket inner liner 300 enters the first panel slot 110 of the socket panel 100, thereby fixing the socket inner liner 300 to the socket panel 100, and thus completing the assembly of the socket assembly 10.

[0058] This utility model's technical solution allows for the separate installation of the socket housing assembly and the socket wiring harness assembly, facilitating the installation of the socket assembly 10 onto external devices and improving assembly efficiency. Specifically, the socket shield 200 of the socket housing assembly is installed within the panel cavity of the socket panel 100, which is used for installation on external devices. After both the socket panel 100 and the socket shield 200 are installed, the socket wiring harness assembly is then installed onto the socket housing. This allows the socket housing assembly to be installed onto the battery panel first, followed by the insertion of the wiring harness assembly, eliminating the need for the wiring harness to be installed, resulting in a lighter overall design. The socket short connector of the socket wiring harness assembly is inserted into the interior of the socket inner liner 300, which is then inserted into the socket shield cavity. The inner liner 300 is then inserted into the socket shield cavity and secured to the first panel slot 110 via a cantilever boss 320. Furthermore, the detachable connection between the socket housing and the socket wiring harness assembly makes cable connection, replacement, and maintenance operations more convenient.

[0059] To improve the stability of the connection between the socket shield 200 and the socket panel 100, in one embodiment, the socket shield 200 is provided with shield barbs 210, the socket panel 100 is provided with a second panel slot 130, the shield barbs 210 are engaged in the second panel slot 130, the socket shield 200 is provided with a flange 220, and the socket panel 100 is also provided with a second panel end face 140, the flange 220 is in contact with the second panel end face 140.

[0060] In the specific implementation process, refer to Figures 1 to 3As shown, the barbs 210 of the shielding component are provided on the side wall of the socket shielding component 200, and a second panel slot 130 is opened at a corresponding position on the side wall of the socket panel 100. Specifically, one end of the barbs 210 of the shielding component is connected to the socket shielding component 200, and the other end extends obliquely away from the socket shielding component 200. The socket shielding component 200 is inserted into the panel cavity of the socket panel 100, so that the barbs of the socket shielding component 200 are engaged in the second panel slot of the socket panel 100, thereby restricting the movement of the socket shielding component 200 in the panel cavity and completing the self-locking of the socket shielding component 200. At the same time, one end of the socket shielding component 200 is also provided with a flange 220. The socket panel 100 has a second panel end face 140, which is adapted to the flange 220. After the socket shielding component 200 is inserted into the panel cavity, one side of the flange 220 fits against the second panel end face 140, thereby restricting the displacement of the socket shielding component 200 in the panel cavity. It should be noted that the flange 220 and the second panel end face 140 cooperate to restrict the displacement direction of the socket shield 200, which is opposite to the direction of the shield barb 210 and the second panel slot 130 that restrict the displacement of the socket shield 200 in the panel cavity, thereby achieving the fixation of the socket shield 200.

[0061] Furthermore, the flange 220 is provided with a limiting hole 221, and the socket panel 100 is provided with a limiting post 150, which is engaged in the limiting hole 221. In specific implementation, the limiting post 150 is provided on the end face 140 of the second panel. When the socket shield 200 is inserted into the panel cavity, the limiting post 150 is engaged in the limiting hole 221, which can prevent the socket shield 200 from shifting position and from falling off.

[0062] refer to Figure 8 As shown, in one embodiment, the socket housing assembly further includes a steel sleeve 160, and the socket panel 100 is provided with mounting holes 170, with the steel sleeve 160 interference-fitted into the mounting holes 170. In specific implementations, multiple mounting holes 170 are spaced apart along the circumference of the socket panel 100 and are used to connect screws and other connectors to lock and fix the socket housing assembly to an external device. It is understood that the socket panel 100 is a plastic part, and the steel sleeve 160 within the mounting holes 170 can improve the strength of the socket panel 100, preventing deformation of the socket panel 100 during locking and fixing, which would affect the connection strength.

[0063] The socket housing assembly also includes a socket sealing ring 180. The socket panel 100 has a socket sealing groove 181, and the socket sealing ring 180 is disposed within the socket sealing groove 181. The socket sealing groove 181 is located on the side of the socket panel 100 facing and in contact with the external device. The sealing ring also contacts the surface of the external device to improve the sealing between the socket panel 100 and the external device, preventing water or dust from entering the interior of the external device from between them.

The first connecting pressure plate 411 presses and connects the first connecting part 421.

[0065] Understandably, the power male terminal 410 has barbs, and the inner wall of the first insertion channel of the socket inner tube 300 has a groove. In this embodiment, after the power male terminal 410 is inserted into the first insertion channel, the barbs lock into the groove to complete self-locking, preventing the power male terminal 410 from falling out. The power male terminal 410 passes through the first male terminal sealing ring 420, so that the first male terminal sealing ring 420 is tightly fitted around the outer circumference of the wire of the power male terminal 410. The first male terminal sealing ring 420 has a first connecting part 421 with a relatively small outer diameter. The first connecting pressure plate 411 is a sheet metal structure and is used to press and connect the first connecting part 421 to fix the first male terminal sealing ring 420. The first male terminal sealing ring 420 is also used to seal the first insertion channel.

[0066] The socket terminal 400 also includes a signal male terminal 430. The socket inner tube 300 is provided with a second insertion channel. The signal male terminal 430 is inserted into the second insertion channel. The signal male terminal 430 is fitted with a second male terminal sealing ring 440.

[0067] Understandably, the signal male terminal 430 has barbs, and the inner wall of the second insertion channel of the socket inner tube 300 has a groove. In this embodiment, after the signal male terminal 430 is inserted into the second insertion channel, the barbs lock into the groove to complete self-locking, preventing the signal male terminal 430 from falling out. The signal male terminal 430 passes through the second male terminal sealing ring 440, so that the second male terminal sealing ring 440 is tightly fitted around the outer circumference of the wire of the signal male terminal 430. The second male terminal sealing ring 440 has a second connecting part 441 with a relatively small outer diameter. The second connecting pressure plate 431 is a sheet metal structure and is used to press and connect the second connecting part 441 to fix the second male terminal sealing ring 440. The second male terminal sealing ring is also used to seal the second insertion channel.

[0068] refer to Figures 4 to 7As shown, in one embodiment, the direct-insertion high-voltage connector further includes a plug assembly 20, which includes a plug housing 500, a plug inner tube 700, a plug terminal 800, and a locking member 520. The plug housing 500 has a plug cavity, and a plug shield 600 is provided inside the plug cavity. The plug shield 600 has a plug shield cavity, and the plug housing 500 also has a plug slot 510.

[0069] refer to Figure 10 and Figure 12 As shown, in the specific implementation process, the plug assembly 20 is used to plug into the socket assembly 10 to complete signal and electrical transmission. Specifically, the plug housing 500 has a locking member 520 with a locking groove 521. The socket panel 100 of the socket assembly 10 has a locking buckle 190. After the plug assembly 20 is inserted into the socket assembly 10, the locking port engages with the locking groove 521, thereby fixing the plug assembly 20 and the socket assembly 10 to ensure the stability of the transmission.

[0070] In this embodiment, the plug shield 600 is inserted into the plug cavity of the plug housing 500, the plug terminal 800 is inserted into the plug inner tube 700, and the plug inner tube 700 is inserted into the plug shield cavity of the plug shield 600, thus assembling the plug assembly 20. Specifically, refer to... Figure 6 As shown, the buckle 710 of the plug inner tube 700 is engaged in the plug slot 510 of the plug housing 500, thereby fixing the plug inner tube 700 to the plug housing 500.

The plug shield 600 has a socket 610 communicating with the plug shield cavity, and the fourth connecting part 822 is interference-fitted with the socket 610.

[0072] In the specific implementation process, it is understandable that the power female terminal 810 is inserted into the third insertion channel of the plug inner tube 700. First, the power female terminal 810 passes through the hole in the plug housing 500, the insertion hole 610 of the plug shield 600, and the plug shield ring 820. The plug shield ring 820 is made of metal and has a third connecting part 821 with a relatively small outer diameter. The third connecting part 821 presses against the wire connected to the power female terminal 810. Then, the power female terminal 810 is inserted into the plug inner tube 700, and the barbs of the power female terminal 810 engage with the groove in the plug inner tube 700 to complete self-locking. After placement, the power female terminal 810 is retracted and falls off. Furthermore, the plug shield 600 is made of metal and has an insertion hole 610 at one end. The edge of the insertion hole 610 is connected to a petal-shaped structure, and the petal-shaped structure and the insertion hole 610 are respectively press-fitted with the fourth connecting part 822 of the plug shield 600.
