[0087] A high-voltage connector is an electrical connector used to connect high-voltage circuits, commonly used in applications requiring the transmission of high voltage or high power, such as electric vehicles, power transmission systems, industrial equipment, aerospace, etc.

[0088] The high-voltage connector includes a protective shell, a fuse and a fuse terminal, the fuse and the fuse terminal are both placed in the protective shell, and the fuse is connected with the fuse terminal, which plays a role in protecting the high-voltage circuit.

[0089] However, the high-voltage connector is inconvenient to install and use in a narrow space.

[0090] Therefore, the fuse terminal and the high-voltage connector are provided.

[0091] When the high-voltage connector is installed and used in a narrow space, the worker can replace the fuse terminal, that is, replace the fuse terminal with the first connecting part arranged parallel to the extension direction of the fuse with the fuse terminal with the first connecting part arranged perpendicular to the extension direction of the fuse, so as to change the direction of the plug-in end of the socket and adapt to the plug-in work in the narrow space.

[0092] Compared with the fuse terminal provided in the high-voltage connector in the prior art, the fuse terminal provided in the application can solve the problem that the high-voltage connector is inconvenient to use in a narrow space.

[0093] The technical solutions of the embodiments of the application will be described in detail below with reference to the drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments.

[0094] The application provides a fuse terminal for a socket of a high-voltage connector.

[0095] Referring to Figures 1 to 3 and Figures 6 to 8 The fuse terminal includes a first connecting part for connecting with a fuse, and a second connecting part 222a arranged on the first connecting part parallel or perpendicular to the extension direction of the fuse.

[0096] In the embodiments of the application, when the high-voltage connector is installed and used in a narrow space, the worker can replace the fuse terminal, that is, replace the fuse terminal with the first connecting part arranged parallel to the extension direction of the fuse with the fuse terminal with the first connecting part arranged perpendicular to the extension direction of the fuse, so as to change the direction of the plug-in end of the socket and adapt to the plug-in work in the narrow space.

[0097] Compared with the fuse terminal provided in the high-voltage connector in the prior art, the fuse terminal provided in the application can solve the problem that the high-voltage connector is inconvenient to use in a narrow space.

[0098] Referring to Figure 3 and Figure 8 In some embodiments, the first connecting part includes a connecting sleeve 222b sleeved on the outside of the fuse.

[0099] It should be noted that the connection mode of the first connecting part and the fuse is not limited in the present application. Specifically, in the above embodiment, the connecting sleeve 222b is used as a bridge for electrically connecting the first connecting part and the fuse. This not only effectively prevents the fuse terminal from accidentally separating from the fuse, but also improves the transmission efficiency of the current between the first connecting part and the fuse.

[0100] Referring to Figures 1 to 8 The present application also provides a high-voltage connector, which comprises a plug 100, a socket 200, and a high-voltage connector. The plug 100 comprises a shell 110 and a first plug core assembly 120, and the first plug core assembly 120 is connected in the shell 110. The socket 200 comprises a mounting seat 210, a second plug core assembly 220, and two first end covers 230. The mounting seat 210 has a receiving cavity, and the second plug core assembly 220 comprises a fuse 221 and a first fuse terminal 222. The fuse 221 and the first fuse terminal 222 are connected in the receiving cavity. First openings are formed in the two sides of the mounting seat 210 and communicate with the receiving cavity. The first end covers 230 are detachably installed in the first openings to seal the first openings. The first fuse terminal 222 is the fuse terminal in any of the above embodiments. The shell 110 is inserted into the mounting seat 210 to electrically connect the first plug core assembly 120 and the fuse 221.

[0101] The first fuse terminal 222 in the present application and the fuse terminal in any of the above embodiments have the same structure and can bring the same or similar technical effects. Therefore, the detailed description is not repeated here, and the reader can refer to the description of the above embodiments.

[0102] In the present embodiment, when normally connected, the shell 110 is inserted into the mounting seat 210 to electrically connect the first plug core assembly 120 and the fuse 221, thereby realizing the insertion of the plug 100 and the socket 200. When the fuse 221 needs to be replaced on site, the insertion of the shell 110 into the mounting seat 210 is released, and the first end cover 230 on the side of the mounting seat 210 facing the shell 110 is opened. At this time, the fuse 221 originally hidden inside the mounting seat 210 is exposed to the external environment. The failed fuse 221 is pulled out, and a new fuse 221 is installed in the mounting seat. The first end cover 230 is resealed, and the replacement of the fuse 221 is completed.

[0103] Compared with the replacement operation of the fuse 221 in the prior art, the high-voltage connector provided in the present embodiment can solve the problems of complex replacement process, inconvenient replacement operation, and low replacement efficiency of the fuse 221. At the same time, the mounting seat 210 does not need to be opened during the whole replacement process of the fuse 221, which avoids the entry of foreign matters in the external environment into the mounting seat 210, thereby causing the risk of short circuit of the fuse 221, and improves the safety and reliability of the high-voltage connector.

[0104] In some embodiments, the first end cover 230 is provided with a clamping portion (not shown), and the mounting seat 210 is provided with a buckling portion (not shown), the clamping portion and the buckling portion are matched with each other to fix the first end cover 230 at the first opening.

[0105] It should be noted that in the present application, the connection mode of the first end cover 230 and the mounting seat 210 is not limited, and the detachable installation of the first end cover 230 can be met. Specifically, in the above embodiment, the clamping portion is provided on the first end cover 230, and the buckling portion is provided on the mounting seat 210, so that the worker only needs to press or shake the first end cover 230 and the like simple operation, and the installation or disassembly of the first end cover 230 can be completed, thereby improving the replacement efficiency of the fuse 221.

[0106] Referring to Figures 1 to 3 In some embodiments, the fuse 221 is integrally formed with a shunt, and the second plug core assembly 220 further comprises: a shunt terminal 223, the shunt terminal 223 comprising a third connecting portion 223a and at least one extension arm 223b, the third connecting portion 223a being connected with the extension arm 223b, the third connecting portion 223a being connected to the first fuse terminal 222, and the extension arm 223b being located at the circumferential side of the fuse 221.

[0107] The existing high-voltage connector is only provided with a fuse 221, and does not have a shunt, but in the specific use process, the shunt is an indispensable connector component, which can measure the current in the high-voltage circuit, so the worker needs to design the shunt separately, and reserve the installation position of the shunt in the high-voltage connector, which is very cumbersome in the operation process. Therefore, in the above embodiment, the fuse 221 and the shunt are designed as an integrated structure, without the need to design the shunt separately, while reducing the overall volume of the high-voltage connector, making the structure of the high-voltage connector more compact.

[0108] Further, in some embodiments, the mounting seat 210 comprises a first shell 211 and a second shell 212, the first shell 211 and the second shell 212 are communicated, and the first shell 211 and the second shell 212 have an included angle therebetween; the fuse 221 and the shunt terminal 223 are located in the first shell 211, and the shunt terminal 223 is located in the second shell 212.

[0109] In the above embodiments, the mounting seat 210 is combined by the first shell 211 and the second shell 212, and an included angle is formed between the first shell 211 and the second shell 212 to change the direction of the plug-in end of the mounting seat 210, so as to adapt to the plug-in operation in a narrow space. Of course, the worker can adjust the included angle between the first shell 211 and the second shell 212 according to the specific use scene of the high-voltage connector. For example, when the high-voltage connector is used in a narrow space, an included angle of 90 degrees (see Figures 1 to 3 ) is adopted; and when the high-voltage connector is used in an open space, an included angle of 180 degrees (see Figures 6 to 8 ) can be adopted to reduce the manufacturing cost.

[0110] Referring to Figure 2 , in some embodiments, the socket shielding member 250 is covered on the cavity wall of the accommodating cavity.

[0111] Here, the socket shielding member 250 is covered on the cavity wall of the accommodating cavity to form a shielding layer, which can effectively block the external electromagnetic and radio frequency from entering the inside of the socket 200, thereby improving the anti-interference ability and reliability of the high-voltage connector and ensuring the stable operation of the high-voltage connector in a complex electromagnetic environment.

[0112] Meanwhile, the material of the shielding member 250 is not required and can be copper or aluminum, etc., and the worker can select the material according to the specific use scene of the high-voltage connector.

[0113] Referring to Figures 1 to 3 , in some embodiments, the socket 200 further includes a sealing ring 240, and the peripheral edge of the mounting seat 210 is provided with an extension 213, and an annular groove 213a is formed on the side of the extension 213 away from the shell 110 to accommodate the sealing ring 240.

[0114] Here, the sealing ring 240 is additionally provided to further enhance the sealing performance between the mounting seat 210 and the mounting surface, so as to avoid the foreign matters in the external environment from entering the mounting seat 210 and causing the risk of short circuit of the fuse 221.

[0115] Meanwhile, the sealing ring 240 is accommodated in the annular groove 213a formed on the extension 213, so as to prevent the gap between the mounting seat 210 and the mounting surface caused by the volume of the sealing ring 240. Of course, the worker can select the shape and material of the sealing ring 240 according to the specific use scene of the high-voltage connector, so as to ensure the good sealing performance between the mounting seat 210 and the mounting surface.

[0116] Referring to Figures 1 to 5In some embodiments, the connection assembly 300 further comprises a clamping piece 310 and a clamping fastener 320, one of the clamping piece 310 and the clamping fastener 320 is arranged on the shell 110, and the other is arranged on the mounting seat 210; the clamping piece 310 is configured to be clamped with the clamping fastener 320 when the shell 110 and the mounting seat 210 are plugged.

[0117] In order to meet the contact pressure and sealing requirements required for plugging of the high-voltage connector, while avoiding accidental disconnection of the plug 100 and the socket 200. Therefore, in the above-mentioned embodiments, the clamping piece 310 and the clamping fastener 320 are arranged, which can be clamped with each other when the plug 100 and the socket 200 are plugged in place, so as to limit the connection state of the plug 100 and the socket 200, thereby improving the connection stability of the plug 100 and the socket 200.

[0118] Further, referring to Figures 4 to 5 In some embodiments, the connection assembly 300 further comprises a clamping piece 330, and a second opening 311 is formed on one side of the clamping piece 310; the clamping piece 330 is configured to be inserted into the second opening 311 and abut against the clamping fastener 320 when the shell 110 and the mounting seat 210 are plugged.

[0119] In the above-mentioned embodiments, the clamping piece 330 is arranged, which can abut against the clamping fastener 320 when the clamping piece 310 and the clamping fastener 320 are clamped with each other, thereby forming a secondary limiting position for the clamping fastener 320, so as to limit the connection state of the plug 100 and the socket 200, and further improve the connection stability of the plug 100 and the socket 200.

[0120] Referring to Figures 4 to 5 In some embodiments, the first plug core assembly 120 comprises: a connecting seat 121, a plurality of connecting protrusions 121a are arranged on the connecting seat 121; a plug shielding piece 122, the plug shielding piece 122 is sleeved outside the connecting seat 121; and a second fuse terminal 123, the second fuse terminal 123 is connected in the connecting protrusion 121a; the second fuse terminal 123 is electrically connected with the fuse 221 when the shell 110 and the mounting seat 210 are plugged.

[0121] The plug shielding piece 122 is sleeved outside the connecting seat 121 to form a shielding layer, which can effectively block external electromagnetic and radio frequency from entering the inside of the plug 100, thereby improving the anti-interference ability and reliability of the high-voltage connector, and ensuring the stable operation of the high-voltage connector in a complex electromagnetic environment.

[0122] Meanwhile, since the connecting seat 121 is provided with a plurality of connecting protrusions 121a, the single plug shielding member 122 is difficult to achieve a good shielding effect on the connecting seat 121. In the specific implementation, the plug shielding member 122 is divided into two parts, one part of the plug shielding member 122 is sleeved outside the base end of the connecting seat 121, and the other part of the plug shielding member 122 is sleeved outside the connecting protrusion 121a, so as to achieve a shielding dead angle; and a sealing member is arranged between the plug shielding members 122, so as to enhance the sealing property of the shell 110.

[0123] Further, referring to Figures 4 to 5 In some embodiments, the plug 100 further comprises a cable joint 130, the cable joint 130 is connected at the end of the shell 110 away from the mounting seat 210, and the cable joint 130 is provided with a cable sealing ring 131; a second end cover 132 is sleeved at the opening of the cable joint 130, so as to fix the cable; a wire hole is formed in the plug shielding member 122, for the cable to pass through, and the wire hole is connected with the second fuse terminal 123, and a shielding ring 140 is arranged between the wire hole and the cable.

[0124] In the above embodiments, the cable sealing ring 131 is arranged, so as to enhance the sealing property of the shell 110; and the second end cover 132 is sleeved at the opening of the cable joint 130, so as to limit the cable and prevent the swing amplitude from being too large, thereby affecting the connection stability of the plug 100 and the socket 200.

[0125] Meanwhile, the shielding ring 140 is sleeved outside the cable, so as to form a shielding layer, which can effectively block the electromagnetic and radio frequency inside the cable from entering the inside of the plug 100, thereby improving the anti-interference ability and reliability of the high-voltage connector, and ensuring the stable operation of the high-voltage connector in a complex electromagnetic environment.
