[0024] Please refer to Figures 1-3 As shown, a socket connector for increasing electrical isolation includes a housing 1, and a plurality of pins 2 are provided in the housing 1. An insulating pin cap 3 is sleeved on the end of the pin 2 to increase the electrical clearance and creepage distance between two adjacent pins 2.

[0025] Specifically, by sleeving an insulating pin cap on the top of the pin in the socket connector, since the pin cap is made of insulating material, when the plug is pulled out and the user accidentally touches the socket, the pin cap at this time can play an insulating role. Not only will the user not have a safety hazard of electric shock, but the socket connector also meets the requirements of IP20. In addition, the insulating pin cap also increases the electrical clearance and creepage distance, which can meet the high-voltage use environment of the socket connector; that is, while the insulating pin cap provides guarantee for customer safety, it also increases the electrical clearance and creepage distance, which can meet the high-voltage resistance requirements of the product.

[0026] In this embodiment, an indented jack 4 is provided at the end of the pin 2, and the insulating pin cap 3 is inserted into the jack 4. Specifically, the insulating pin cap is inserted into the jack, which is convenient for disassembly and assembly and is simple and effective to use.

[0027] In this embodiment, a plug-in portion 5 is provided at the bottom of the insulating pin cap 3, and the plug-in portion 5 has elastic deformation.

[0028] Specifically, the plug-in portion has elastic deformation, so that after the plug-in portion is inserted into the jack, due to the elastic deformation characteristics of the plug-in portion itself, the plug-in portion is squeezed when inserted into the jack. When the plug-in portion is completely placed in the jack, the plug-in portion rebounds to its original state, so that the plug-in portion is stably connected to the pin, making the insulating pin cap not easy to fall off.

[0029] In this embodiment, the plug-in portion 5 includes a first plug-in portion 501 and a second plug-in portion 502, and a through groove 6 is provided between the first plug-in portion 501 and the second plug-in portion 502.

[0030] Specifically, the plug-in portion is divided into two parts, the first plug-in portion and the second plug-in portion, and a through groove is provided between them. The through groove enables the plug-in portion to have a deformation space when inserted into the jack. After the plug-in portion is completely placed in the jack, the first plug-in portion and the second plug-in portion recover to their original states after releasing the extrusion force applied by the jack.

[0031] In this embodiment, abutting portions 7 are provided on both the first plugging portion 501 and the second plugging portion 502, a butting baffle 8 is provided at the opening of the jack 4, and the butting portion 7 abuts and fixes with the butting baffle 8.

[0032] Specifically, after the plugging portion is inserted into the jack, the extrusion force applied by the jack to the plugging portion disappears, the plugging portion returns to its original state, and the butting portion and the butting baffle are butted and cooperated up and down, so that the needle cap and the pin are fixedly connected.

[0033] In this embodiment, the insulating needle cap 3 is made of plastic. Plastic has good insulation properties and is common and durable.

[0034] In this embodiment, the housing 1 includes an outer shell 101, and the pin 2 is disposed inside the outer shell 101;

[0035] It further includes a cover plate 102. One end of the pin 2 is inserted into the cover plate 102, and the cover plate 102 is screwed and fixed with the outer shell 101. The cover plate and the outer shell are fixed by screws, which facilitates the installation of the pin and is convenient for disassembly and assembly.

[0036] In this embodiment, the diameter of the end of the pin 2 inserted into the cover plate 102 is smaller than the diameter of the end disposed inside the outer shell 101, and a baffle 11 is provided on the outer periphery of the pin 2.

[0037] Specifically, the diameter of the end of the pin inserted into the cover plate is smaller than the diameter of the end disposed inside the outer shell, and a baffle is further provided on the outer periphery of the pin, so that the pin is placed on the cover plate. Without other components for fixation, that is, when the cover plate and the outer shell are fixed, the pin is fixedly clamped between the cover plate and the outer shell to prevent it from detaching and shaking.

[0038] In this embodiment, a groove 9 is provided on the outer periphery of the outer shell 101, and a matching sealing ring 10 is embedded in the groove 9.

[0039] Specifically, a sealing ring is provided on the outer shell, and the position of the sealing ring enables the socket connector to meet the IP67 sealing requirements after being assembled into the chassis.

[0040] The above are only the preferred embodiments of the present application and are not used to limit the scope of implementation of the present application. Other embodiments with the same or similar principles and basic structures as the present application are within the protection scope of the present application.
