[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0046] like Figure 1-Figure 7As shown, an embodiment of the present invention proposes a PDU, including at least two electronic wires 1 with an electrical connection portion 13, a metal connector 2 clamped with the electronic wire 1 at the electrical connection portion 13, and a socket module 3; the electronic wire 1 includes a metal wire body 11 and at least two spaced-apart insulating sleeves 12 sleeved on the outside of the metal wire body 11; the gap between adjacent insulating sleeves 12 forms the electrical connection portion 13; the metal connector 2 includes a clamping portion 21 clamped with the metal wire body 11 and a plug-in portion 22 connected to the clamping portion 21; the plug-in portion 22 is provided with a plug-in hole 221, and the socket module 3 is provided with a socket foot 31 plugged into the plug-in hole 221.

[0047] In an embodiment of the present invention, the electronic wire 1 includes an internal metal wire body 11 and at least two insulating sleeves 12 sleeved on the outside of the metal wire body 11. There is a gap between adjacent insulating sleeves 12 to expose the metal wire body 11. The gap forms an electrical connection portion 13. The clamping portion 21 of the metal plug-in component 2 is clamped with the metal wire body 11 at the electrical connection portion 13 to achieve electrical connection. The socket pin 31 on the socket module 3 is plugged into the plug hole 221 opened on the plug-in portion 22 of the metal plug-in component 2, thereby achieving electrical connection between the socket pin 31 on the socket module 3 and the metal wire body 11 through the metal plug-in component 2. Therefore, the socket pin 31 and the metal wire body 11 are not connected by traditional welding. During production, it is only necessary to clamp the clamping portion 21 and the metal wire body 11 and plug the socket pin 31 into the plug hole 221 to complete the assembly and production of the PDU. Compared with the welding method, the production efficiency of the PDU is significantly improved.

[0048] It is understandable that the process of machining the electrical connection portion 13 on the electronic wire 1 may be:

[0049] The electronic wire 1 having a metal wire body 11 and an insulating layer covering the outside of the metal wire body 11 is subjected to a stripping process, and at least one notch is stripped on the insulating layer to expose the metal wire body 11, and the notch is an electrical connection portion 13. When there are more than two insulating sleeves 12, the distance between adjacent socket modules 3 is first calculated, the interval for stripping the electronic wire 1 is determined, the stripping program is set, and the machine automatically strips the wires.

[0050] Alternatively, at least two spaced-apart insulating sleeves 12 are sleeved on the outside of the metal wire body 11 , and the gaps between adjacent insulating sleeves 12 form the electrical connection portion 13 .

[0051] The clamping part 21 and the metal wire body 11 can be clamped and pressed by a machine. That is, the steps of stripping, clamping and plugging are all operated by automated equipment, which significantly improves production efficiency compared with manual welding.

[0052] Please also refer to Figure 2 and Figure 4As another specific embodiment of the PDU provided by the present invention, it also includes an insulating shell 4 for covering the electrical connection portion 13, and the insulating shell 4 is sleeved on the outside of the clamping portion 21. The insulating shell 4 covers the electrical connection portion 13 and is sleeved on the outside of the clamping portion 21 to improve the safety of the PDU.

[0053] Please also refer to Figure 2 and Figure 4 As another specific embodiment of the PDU provided by the present invention, the insulating shell 4 is sealed and connected to the adjacent insulating sleeve 12. The insulating shell 4 is sealed and connected to the adjacent insulating sleeve 12, which can achieve waterproof and dustproof, and prevent water and dust from entering through the gap between the insulating shell 4 and the insulating sleeve 12 and adhering to the metal wire body 11.

[0054] Please also refer to Figure 5-Figure 6 As another specific embodiment of the PDU provided by the present invention, the clamping part 21 includes a bottom plate 213 and a first clamping plate 211 and a second clamping plate 212 respectively disposed on opposite sides of the bottom plate 213; the metal wire body 11 is clamped between the first clamping plate 211 and the second clamping plate 212, and an electrical connection is achieved while achieving clamping fixation. Since the first clamping plate 211 and the second clamping plate 212 are both made of metal, the ends of the first clamping plate 211 and the second clamping plate 212 can be bent so that the first clamping plate 211 and the second clamping plate 212 are pressed against the surface of the metal wire body 11, so as to further improve the stability of the clamping between the clamping part 21 and the metal wire body 11.

[0055] Please also refer to Figure 5-Figure 6 As another specific embodiment of the PDU provided by the present invention, the plug-in portion 22 is connected to the bottom plate 213, and the plug-in portion 22 and the bottom plate 213 are perpendicular to each other. The plug-in portion 22 and the bottom plate 213 are perpendicular to each other, thereby reducing the volume occupied by the entire metal plug-in component 2, thereby realizing the miniaturization of the PDU.

[0056] Please also refer to Figure 2-Figure 4 As another specific embodiment of the PDU provided by the present invention, an abutment plate 41 is provided at a position corresponding to the insulating shell 4 and the clamping portion 21, and one end of the abutment plate 41 away from the insulating shell 4 abuts against the socket module 3. The plug-in portion 22 and the bottom plate 213 are perpendicular to each other, and the bottom plate 213 is relatively parallel to the metal wire body 11, so the plug-in portion 22 protrudes from the bottom plate 213, so that there is a certain gap between the clamping portion 21 as a whole and the socket module 3, and an abutment plate 41 is provided at a position corresponding to the insulating shell 4 and the clamping portion 21, and one end of the abutment plate 41 away from the insulating shell 4 abuts against the socket module 3, so that when the socket foot 31 is plugged and matched with the plug-in portion 22, the abutment plate 41 abuts against the socket module 3 simultaneously, ensuring that both ends of the insulating shell 4 are in good contact with the socket module 3, so as to improve the stability of the connection.

[0057] Please also refer to Figure 1 As another specific implementation of the PDU provided by the present invention, the number of electronic wires 1 is three, and the three electronic wires 1 are respectively a neutral wire, a live wire and a ground wire; the neutral wire, the live wire and the ground wire are respectively electrically connected to the three socket pins 31 on the socket module 3.

[0058] Of course, the number of the electronic wires 1 can also be two, and the two electronic wires 1 are a neutral wire and a live wire respectively. The neutral wire and the live wire are electrically connected to the two socket pins 31 on the socket module 3 respectively.

[0059] Please also refer to Figure 1 As another specific implementation of the PDU provided by the present invention, the metal connector 2 is a copper block; the metal wire body 11 is a copper wire.

[0060] Please also refer to Figure 5 As another specific embodiment of the PDU provided by the present invention, the plug-in portion 22 is provided with a limiting hole 222 on the inner wall of the plug-in hole 221, and the socket pin 31 is provided with a limiting protrusion 311 adapted to the limiting hole 222. The limiting protrusion 311 is clamped in the limiting hole 222 to prevent the socket pin 31 from sliding relative to the plug-in portion 22, so as to ensure the stability of the plug-in.

[0061] Please also refer to Figure 1 As another specific embodiment of the PDU provided by the present invention, it also includes a mounting shell 5; the socket module 3 is fixedly connected to the mounting shell 5, which can be a snap connection or a screw connection. When there are multiple socket modules 3, multiple socket modules 3 are simultaneously installed in one mounting shell 5 to form an integrated PDU.

[0062] The embodiment of the present invention further provides a method for making a PDU, which can be used to make the PDU in the above embodiment, and includes the following steps:

[0063] S100, respectively arranging at least two spaced-apart insulating sleeves 12 outside at least two metal wire bodies 11, wherein the gaps between adjacent insulating sleeves 12 form electrical connection portions 13;

[0064] S200, clamping the clamping portion 21 of the metal connector 2 to the electrical connection portion 13 and the metal wire body 11;

[0065] S300 , inserting the socket pin 31 on the socket module 3 into the plug hole 221 of the metal plug connector 2 .

[0066] The electronic wire 1 includes an internal metal wire body 11 and at least two insulating sleeves 12 sleeved on the outside of the metal wire body 11. There is a gap between adjacent insulating sleeves 12 so that the metal wire body 11 is exposed, and the gap forms an electrical connection portion 13. The clamping portion 21 of the metal plug connector 2 is clamped with the metal wire body 11 at the electrical connection portion 13 to achieve electrical connection. The socket pin 31 on the socket module 3 is plugged into the plug hole 221 opened on the plug portion 22 of the metal plug connector 2, thereby achieving electrical connection between the socket pin 31 on the socket module 3 and the metal wire body 11 through the metal plug connector 2. Therefore, the socket pin 31 and the metal wire body 11 are not connected by traditional welding. During production, it is only necessary to clamp the clamping portion 21 and the metal wire body 11 and plug the socket pin 31 into the plug hole 221 to complete the assembly and production of the PDU. Compared with the welding method, the production efficiency of the PDU is significantly improved. The clamping part 21 and the metal wire body 11 can be clamped and pressed by a machine. That is, the steps of stripping, clamping and plugging are all operated by automated equipment, which significantly improves production efficiency compared with manual welding.

[0067] Furthermore, as another specific implementation of the method for making a PDU provided by the present invention, the method further includes the following steps:

[0068] S400, providing an insulating shell 4 covering the electrical connection portion 13, and sealingly connecting the insulating shell 4 and the insulating sleeve 12 by ultrasonic welding.

[0069] The insulating shell 4 is sealedly connected to the adjacent insulating sleeve 12 to achieve waterproof and dustproof properties, thereby preventing water and dust from entering through the gap between the insulating shell 4 and the insulating sleeve 12 and adhering to the metal wire body 11 .

[0070] Further, as another specific implementation of the method for making a PDU provided by the present invention, step S100 is specifically: stripping the electronic wire 1 having a metal wire body 11 and an insulating layer covering the outside of the metal wire body 11, stripping at least one notch on the insulating layer and exposing the metal wire body 11, the notch being the electrical connection portion 13. When there are more than two insulating sleeves 12, firstly calculate the distance between adjacent socket modules 3, determine the interval for stripping the electronic wire 1, set the stripping program, and perform automatic stripping by the machine.

[0071] Furthermore, as another specific implementation of the method for manufacturing the PDU provided by the present invention, step S100 is specifically as follows: at least two insulating sleeves 12 spaced apart from each other are sleeved on the outside of the metal wire body 11 , and the gaps between adjacent insulating sleeves 12 form electrical connection portions 13 .

[0072] Furthermore, as another specific implementation of the PDU manufacturing method provided by the present invention, the clamping portion 21 includes a base plate 213 and a first clamping plate 211 and a second clamping plate 212 respectively arranged on opposite sides of the base plate 213; step S200 is specifically: clamping the metal wire body 11 between the first clamping plate 211 and the second clamping plate 212, bending the ends of the first clamping plate 211 and the second clamping plate 212 so that the first clamping plate 211 and the second clamping plate 212 are pressed against the surface of the metal wire body 11.

[0073] Since the first clamping plate 211 and the second clamping plate 212 are both made of metal, the ends of the first clamping plate 211 and the second clamping plate 212 can be bent so that the first clamping plate 211 and the second clamping plate 212 are pressed against the surface of the metal wire body 11 to further improve the stability of the clamping between the clamping portion 21 and the metal wire body 11.

[0074] It can be understood that a solution in another specific implementation manner may be a feasible implementation scheme that is further improved on the basis of other embodiments.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
