[0033] like Figures 1 to 10 As shown, an embodiment of the present invention describes an easy-to-assemble angle plug, which includes a housing 1. A plurality of blade pins 2 are arranged inside the housing 1. Connectors 3 are provided between the blade pins 2 and the housing 1. The connectors 3 are respectively engaged with the housing 1 and the blade pins 2.

[0034] During assembly, first ultrasonically weld the copper busbar 10 (or aluminum busbar) to the chip pin 2, then plug and connect the chip pin 2 to the connector 3, and then install the connector 3 one by one into the shell 1, and the connector 3 and the shell 1 are snap-fitted together.

[0035] In this embodiment, the blade pins 2, compared to round pins, do not require traditional circular machining. This not only simplifies the production process and reduces production costs, but also allows for soldering to the copper busbar 10, increasing the plug's current-carrying capacity and meeting the requirements of high-power transmission. Furthermore, the snap-fit connection between the various components facilitates modular design, allowing for the selection of blade pins 2 with appropriate specifications based on current-carrying and safety requirements, simplifying design and assembly. Furthermore, the snap-fit connection between the connector 3, the housing 1, and the blade pins 2 enables quick and secure assembly, improving assembly efficiency and ensuring the plug's stability and reliability during use.

[0036] In a preferred embodiment, the shell 1 is made of metal or alloy.

[0037] In this embodiment, by selecting metal or alloy as the material of the shell 1 and adopting a die-casting molding process, the angled plug is made resistant to high temperatures, collisions, and has excellent electromagnetic shielding performance, ensuring the stable operation of the plug in harsh environments, improving the overall durability and safety of the product, and meeting higher-demand application scenarios.

[0038] like Figure 4 and Figure 10 As shown, in a preferred embodiment, a receiving groove 301 for accommodating the chip pin 2 is provided on the connector 3, a first limiting step 302 is provided in the receiving groove 301, and a second limiting step 201 is provided on the chip pin 2. The first limiting step 302 and the second limiting step 201 are in contact to limit the fitting depth between the chip pin 2 and the connector 3.

[0039] In this embodiment, by providing a receiving groove 301 and a first limiting step 302 on the connector 3, and cooperating with the second limiting step 201 on the chip pin 2, the insertion depth of the chip pin 2 is controlled, thereby simplifying the assembly process, avoiding assembly problems caused by inserting the pin too deep or too shallow, and ensuring the reliability of the connection between the chip pin 2 and the connector 3.

[0040] like Figure 4 、 Figure 8 、 Figure 9 、 Figure 10 As shown, in a preferred embodiment, a first through hole 303 is provided on the connecting member 3, a second through hole 202 is provided on the sheet pin 2, and a connecting pin 4 is provided through the first through hole 303 and the second through hole 202.

[0041] The connecting pin 4 includes a limiting portion 401 that passes through the first through hole 303 and the second through hole 202, a first clip 402 is provided at one end of the limiting portion 401, a first slot 304 that engages with the first clip 402 is provided on the connecting member 3, a baffle 403 is provided at the other end of the limiting portion 401, and a mounting groove 305 for accommodating the baffle 403 is provided on the connecting member 3.

[0042] In this embodiment, a connecting pin 4 is inserted through both the first through-hole 303 and the second through-hole 202 to achieve a secure connection between the chip pin 2 and the connector 3. The stopper 401 of the connecting pin 4 ensures precise positioning between the pin and the connector 3. The engagement of the first latch 402 with the first latching slot 304 prevents the connecting pin 4 from falling out, thereby ensuring a stable connection between the connector 3 and the chip pin 2. Furthermore, a retaining plate 403 at the other end of the stopper 401 and the mounting slot 305 on the connector 3 limit the connection of the connecting pin 4, simplifying the assembly process and improving efficiency.

[0043] like Figure 4 and Figure 10 As shown, in a preferred embodiment, a second buckle 306 is provided on the connecting member 3 , and a clamping plate 101 engaged with the second buckle 306 is provided in the housing 1 .

[0044] In this embodiment, by providing a second snap 306 on the connector 3 and engaging it with the corresponding snap plate 101 in the housing 1, the reliability between the connector 3 and the housing 1 is further enhanced. The cooperation between the second snap 306 and the snap plate 101 not only simplifies the assembly process and improves assembly efficiency, but also prevents the connector 3 from loosening or falling off during use of the plug, thereby extending the product's service life and improving its safety and reliability.

[0045] like Figures 3 to 9 As shown, in a preferred embodiment, the housing 1 is L-shaped, with a wiring port 102 and a plug port 103 at both ends.

[0046] The wiring port 102 is provided with a first sealing member 5. The first sealing member 5 is annular, and multiple protrusions are provided on the inner wall and the outer wall. The outer wall of the first sealing member 5 contacts the inner wall of the wiring port 102, and the inner wall of the first sealing member 5 contacts the outer wall of the connector 3. The wiring port 102 is provided with a first end cover 6. A third buckle 104 is provided on the outer side of the wiring port 102. The first end cover 6 is provided with a second slot 601 that engages with the third buckle 104.

[0047] The plug interface 103 is provided with a sealing groove, in which a second sealing member 7 is provided. The second sealing member 7 is annular, and multiple protrusions are provided on the inner wall and the outer wall. The inner wall of the second sealing member 7 contacts the wall surface of the sealing groove, and the outer wall of the second sealing member 7 contacts the shell 1 of the socket 11. The plug interface 103 is provided with a second end cover 8, and a fourth clip 105 is provided on the inner side of the plug interface 103. The second end cover 8 is provided with a third clip groove 801 that engages with the fourth clip 105.

[0048] In this embodiment, by providing a first seal 5 and a second seal 7 at the wiring port 102 and the plug port 103, respectively, the sealing performance of the plug itself and its mating with the socket 11 is improved. Both the first seal 5 and the second seal 7 are annular in design, and the multiple protrusions provided on their inner and outer walls allow them to fit tightly with the wiring port 102, the plug port 103, and the housing 1 of the socket 11, thereby enhancing the sealing effect and effectively preventing the intrusion of external impurities such as moisture and dust. Furthermore, the engagement of the first end cap 6 with the third snap 104 on the outside of the wiring port 102 and the second end cap 8 with the fourth snap 105 on the inside of the plug port 103 further enhances the overall reliability of the plug, simplifies the assembly process, improves production efficiency, and enhances the safety of the plug in use.

[0049] like Figure 6 As shown, in a preferred embodiment, a signal pin is provided on the second end cover 8, and a signal jack is provided on the socket 11, and the end of the signal pin is above the chip pin 2, that is, the connection between the signal pins is slower than the connection between the chip pin 2 and the busbar on the socket 11, and the separation between the signal pins is faster than the separation between the chip pin 2 and the busbar on the socket 11.

[0050] In this embodiment, by providing a signal pin on second end cap 8 and matching it with the signal jack on socket 11, the connection between the signal pin and the signal jack is performed after the main electrical circuit (i.e., the chip pin 2 and the socket busbar). This allows signal verification before the main electrical circuit is connected, enhancing circuit safety. Furthermore, the signal pin can be disconnected more quickly than the high-voltage circuit, which can quickly cut off the signal in an emergency, improving the intelligence level of the device and enhancing safety and reliability.

[0051] like Figure 6 、 Figure 8 、 Figure 9 As shown, in a preferred embodiment, a limiting groove 307 is provided on the connecting member 3 , and a limiting block 802 inserted into the limiting groove 307 is provided on the second end cover 8 .

[0052] In this embodiment, by providing a limiting groove 307 on the connector 3 and configuring a matching limiting block 802 on the second end cover 8, a more stable and precise connection between the connector 3 and the housing 1 is achieved, preventing the connector 3 from falling off from the housing 1 during the plug-in process, thereby ensuring the stability of the electrical connection.

[0053] like Figure 1 and Figure 2As shown, in a preferred embodiment, the shell 1 is provided with a connecting buckle 9 for connecting to the socket 11, and the connecting buckle 9 includes a power-assisting handle 901 rotatably connected to the shell 1, and the power-assisting handle 901 is provided with an arc groove 902 that cooperates with the connecting column on the socket 11. The power-assisting handle 901 is rotated to change the position of the connecting column in the arc groove 902, so that the plug and the socket 11 are closer to or farther away from each other, and a lock buckle 903 is provided on the power-assisting handle 901, and a card block 106 that engages with the lock buckle 903 is provided on the shell 1.

[0054] In this embodiment, the connection buckle 9 with a power-assisted handle 901 achieves an efficient and convenient connection between the plug and the socket 11. The user simply rotates the power-assisted handle 901 to easily change the position of the connection post within the arcuate slot 902, thereby moving the plug and socket 11 closer or further apart, thereby achieving electrical connection and disconnection between the plug and socket 11. This simplifies the operation process, improves connection efficiency, and provides users with a more comfortable and convenient user experience. Furthermore, the engagement of the lock buckle 903 provided on the power-assisted handle 901 with the block 106 restricts the rotation of the connection buckle 9, further enhancing the stability of the connection between the plug and socket 11.

[0055] like Figure 2 As shown, in a preferred embodiment, a section of the bottom of the chip pin 2 connected to the busbar is provided with a chamfer to reduce its bottom cross-sectional area for easy insertion.

[0056] like Figure 1 and Figure 2 As shown, a connector described in one embodiment of the present invention includes the above-mentioned angled plug that is easy to assemble.

[0057] In this embodiment, the provision of blade pins 2 simplifies the production process and reduces costs compared to round pins. Furthermore, they can be welded to the copper busbar 10, improving the plug's current-carrying capacity and meeting the requirements of high-power transmission. Furthermore, the snap-fit connection between the various components facilitates modular design, allowing for easy assembly by selecting blade pins 2 of appropriate specifications based on current-carrying and safety requirements.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
