DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings to describe the preferred embodiments of the present invention in detail, so as to more clearly understand the purpose, characteristics and advantages of the present invention.

[0026] A sealed high-voltage connector comprises a socket assembly 1 and a plug assembly 2; the socket assembly 1 comprises a socket body 101, a socket metal piece 102, and a cavity 103; wherein the socket metal piece 102 is designed as a groove, a cavity 103 is arranged in the socket body 101, the socket metal piece 102 is located in the cavity 103, a high-voltage line 3 is connected to the socket metal piece 102, and the socket body 101 is fixed to a mounting device; the plug assembly 2 comprises a plug socket 201, a plug metal piece 202, a handle 203, and a fixing ring 204; the plug metal piece 202 is designed as a protrusion, the plug metal piece 202 is arranged in the handle 203, and the high-voltage line 3 is connected to the plug metal piece 202; the handle 203 is arranged in the fixing ring 204, and the fixing ring 204 is arranged in the plug socket 201; the plug metal piece 202 is inserted into the socket metal piece 102 in the cavity 103 and fixed.

[0027] Specifically, the socket body 101 is connected to the socket metal member 102 via the socket fixing copper sheet 104 .

[0028] Specifically, the socket body 101 , the socket metal part 102 and the high-voltage wire 3 are integrally connected through welding pieces and fastening nuts 4 .

[0029] Specifically, the inner cavity at the top of the socket body 101 is filled with insulating glue 5 .

[0030] As a preferred embodiment, the insulating adhesive 5 is epoxy resin filling adhesive, and the epoxy resin filling adhesive is used to isolate the high voltage from the surface of the high-voltage line and the socket assembly to the surface of the installation equipment.

[0031] The present application places a socket metal part (the socket metal part is a standard part on the market) into the socket body, fixes the socket metal part and the socket body together with a socket fixing copper sheet, inserts the high-voltage wire connected at the base into the socket body, and fixes the socket body, the socket metal part and the high-voltage wire together with corresponding welding pieces and fastening nuts; after fixing the metal parts and the high-voltage wire, epoxy resin filling glue is poured into the inner cavity at the top of the socket body, and the socket back cover 7 is covered and waited for the glue to dry before use.

[0032] Specifically, the outer circumference of the handle 203 is provided with external threads, the inner circle of the fixing ring 204 is provided with internal threads, the handle 203 is screwed into the fixing ring 204, the outer circumference of the fixing ring 204 is provided with external threads, the plug socket 201 is provided with internal threads, and the fixing ring 204 is screwed into the plug socket 201.

[0033] Specifically, the gap between the handle 203 and the high-voltage line 3 is filled with insulating glue.

[0034] As a preferred embodiment, the insulating adhesive 5 is epoxy resin filling adhesive, and the epoxy resin filling adhesive is used to isolate the high voltage from the surface of the high-voltage line and the plug assembly to the surface of the installation equipment.

[0035] The metal parts of the plug and the high-voltage wire of the present application are first welded together, and then the welded metal parts of the plug and the high-voltage wire are placed in the handle, and the fixing ring is screwed into the bottom of the handle thread through its own thread, and the handle, the high-voltage wire and the fixing ring are screwed into the plug socket together. When the handle is screwed into the bottom, the fixing ring is rotated in the opposite direction until the handle and the plug socket are locked to each other, and the gap between the handle and the high-voltage wire is filled with epoxy resin filling glue, and the connection between the handle and the high-voltage wire is protected by a heat shrink tube.

[0036] like Figure 2 Specifically, a self-locking nut 6 is sleeved on the plug socket 201, and the plug socket 201 and the socket body 101 are fixed by the self-locking nut 6. When the socket is glued dry, the socket back cover 7 and the socket front cover 8 are matched to be installed in the installation device panel 7, and the plug is inserted into the socket. Tightening the self-locking nut can ensure that the plug and socket are tightly matched and firmly do not fall off.

[0037] Most of the common connectors currently on the market cannot withstand 10KV high voltage, and the connectors that can withstand high voltage are generally expensive and not suitable for use in ordinary consumer industrial industries. The socket body and the plug seat in the utility model are made of ordinary nylon rods. Through the structural design of the application and the ordinary processing method, the connector has certain advantages in cost and safety, and can be widely used in various products and instruments that require high voltage docking.

[0038] The contact area of ​​the metal parts at the connection between the plug and the socket of the utility model reaches 28 square millimeters, and the thickness of the thinnest part of the insulation layer of the shell is about 13 millimeters. Under the premise of the current-carrying area and safety distance of the above specifications, the utility model can solve the problem that the existing products on the market cannot handle high voltage (10KV) and large current (above 50A).

[0039] Through the structural design of the utility model, a cavity is set in the socket body, and the plug metal part is inserted into the socket metal part in the cavity and fixed. When the plug and the socket are connected, there is sufficient isolation space inside to prevent the high voltage of the internal metal part from leaking out when the power is on, thereby ensuring the personal safety of users.
