[0043] Embodiment 1

[0044] This embodiment relates to a charging connector plug, which can improve the convenience of operating the electrical connector 23 in the housing 1, and is beneficial to improving its use reliability.

[0045] In terms of the overall structure, as Figures 1 to 3 shown, the charging connector plug of this embodiment includes a housing 1, a metal row assembly, and a flip cover 3. Among them, the housing 1 has a first cavity and a second cavity. The first cavity extends along a first direction and penetrates through opposite ends of the housing 1. The second cavity extends along a second direction and communicates with the first cavity. The first direction and the second direction are arranged intersectingly. The metal row assembly is disposed on the housing 1 and has a terminal 22 extending from the second cavity into the first cavity, and this terminal 22 is used for electrical connection with a socket.

[0046] The flip cover 3 is rotatably disposed on the housing 1, and the flip cover 3 has a covering position for blocking one end of the first cavity and an open position for releasing the blockage of the first cavity. A holding structure is provided between the flip cover 3 and the housing 1, and the holding structure can hold the flip cover 3 in the open position to facilitate the operation of the electrical connector 23 to connect the terminal 22 and the socket.

[0047] At this time, in the above structure, by providing the rotatable flip cover 3 on the housing 1 and the holding structure between the flip cover 3 and the housing 1, the flip cover 3 can be held in the open position, thereby facilitating the operation of the electrical connector 23 inside the housing 1, enabling the electrical connection to connect the terminal 22 and the socket together, thus avoiding the influence on the installation operation of the connector by the flip cover 3 not being able to be held in the open position and being beneficial to improving the use reliability of the charging connector plug.

[0048] It should be noted that the above-mentioned first direction and second direction are specifically the directions shown in Figure 1 and, preferably, the first direction and the second direction are orthogonally arranged, which is beneficial to making the structural arrangement of the charging connector plug more compact. Of course, it can be understood that the first direction and the second direction can also be arranged in other intersecting ways other than orthogonal.

[0049] Specifically, continue to refer to Figures 1 to 3 and, in combination with Figure 4 shown, as a preferred embodiment, in this embodiment, the housing 1 includes an outer housing 11 and an inner housing 12. Among them, the outer housing 11 has a connected first part 111 and a second part 112, and the inner housing 12 is disposed inside the first part 111. The above-mentioned first cavity is disposed on the inner housing 12, and the second cavity is disposed on the second part 112. And a through hole 121 is provided on the inner housing 12, and the first cavity communicates with the second cavity through the through hole 121. At this time, the housing 1 adopting the structure of the outer housing 11 and the inner housing 12 is beneficial to reducing the manufacturing cost of the housing 1 and is beneficial to the processing and preparation of the housing 1.

[0050] Specifically, the outer housing 11 and the inner housing 12 are preferably made of plastic material to have a good insulation effect. The first part 111 of the outer housing 11 is hollow and forms a cavity, and the inner housing 12 is inserted into the cavity and connected to the outer housing 11. To facilitate improving the connection reliability of the inner housing 12 within the outer housing 11, in this embodiment, the inner housing 12 is snap-connected to the outer housing 11. As a preferred implementation, a snap projection 1113 is provided on the inner wall of the outer housing 11. Correspondingly, a snap hole 122 is provided on the inner housing 12, and the snap projection 1113 can be snapped into the snap hole 122. Through the snap fit of the snap projection 1113 and the snap hole 122, the inner housing 12 is snap-connected within the first part 111 of the outer housing 11. And further, a plurality of snap projections 1113 are arranged oppositely, and similarly, a plurality of snap holes 122 are also arranged oppositely, so as to improve the smoothness of the snap connection.

[0051] Moreover, to ensure the sealing performance between the inner housing 12 and the outer housing 11, in this embodiment, a first sealing ring 10 is provided between the inner housing 12 and the outer housing 11, and the first sealing ring 10 can seal the gap between the inner housing 12 and the outer housing 11.

[0052] For the metal row assembly of this embodiment, see Figure 1 As shown, as a preferred implementation, the metal row assembly includes a plurality of metal rows 21 arranged at intervals. There are also a plurality of terminals 22, and the plurality of terminals 22 are respectively connected to the plurality of metal rows 21 in one-to-one correspondence. The first cavities and the electrical connectors 23 are also a plurality corresponding to each terminal 22 one by one. At this time, it is beneficial to ensure the insulation effect between adjacent terminals 22. And preferably, there are also a plurality of through holes 121, and the plurality of through holes 121 are arranged corresponding to each metal row 21 one by one. At this time, it is beneficial to ensure the insulation effect between adjacent metal rows 21.

[0053] It should be noted that the metal row 21 of this embodiment is preferably an aluminum row. In this way, using the aluminum row as the main conductor, its flat structure can effectively improve the conductivity, and it also makes the assembly and disassembly more convenient. In this embodiment, there are two metal rows 21 arranged at intervals, and there are also two first cavities and two electrical connectors 23 provided. The terminals 22 on each metal row 21 extend from the second cavity into the first cavity and are screwed to the inner housing 12 through self-tapping bolts 7. The electrical connector 23 of this embodiment is preferably a bolt. During specific implementation, the bolt passes through the connection hole on the terminal 22 and is screwed to the socket, and the axial direction of the bolt is preferably arranged along the first direction.

[0054] In addition, it should also be noted that the terminal 22 of this embodiment is made of copper and is welded to the end of the aluminum busbar. At this time, by welding a copper transition terminal 22 to the end of the aluminum busbar, it can not only meet the transmission requirements of stable large current, but also reduce costs and reduce weight. In addition, it should also be noted that in addition to setting a plurality of through holes 121 corresponding to each metal busbar 21 one by one, it can also be set as a single integral one, which is also feasible.

[0055] As a preferred embodiment, the metal busbar assembly of this embodiment further includes a stopper 25, a seal 24 and a tail cover 14. Among them, the stopper 25 and the tail cover 14 are respectively arranged on both sides of the seal 24. Through holes for the metal busbar 21 to pass through are provided on both the stopper 25 and the seal 24. The tail cover 14 is connected to the housing 1 and can sandwich the seal 24 and the stopper 25 between the housing 1 and the tail cover 14.

[0056] Specifically, insulating layers are provided on both metal busbars 21. The seal 24 is sleeved on the outer periphery of the insulating layers of the two metal busbars 21 and is in interference fit with the two metal busbars 21. Moreover, the seal 24 is also in interference fit with the inner wall of the housing 1. In this way, not only the sealing performance after the installation of the metal busbar 21 can be ensured, but also the sealing performance between the housing 1 and the tail cover 14 can be ensured. The setting of the stopper 25 can play a certain supporting role in the width direction and thickness direction of the metal busbar 21, thereby improving the stability of the metal busbar 21 after installation. The tail cover 14 is connected to the housing 1 by snap connection, which is conducive to improving the convenience of assembly and disassembly of the tail cover 14 and the housing 1.

[0057] In this embodiment, preferably, the terminal 22 is bent and has a first straight section 221, a connecting section 222 and a second straight section 223 connected in sequence. The first straight section 221 is connected to the metal busbar 21, and the second straight section 223 is connected to the housing 1. The setting of the structural shape of the terminal 22 makes the position of the terminal 22 deviate towards one end of the housing 1 after it extends into the first installation cavity. At this time, a flip cover 3 is provided at one end of the housing 1 that is far from the terminal 22. In this way, not only a larger space can be provided for the arrangement of the flip cover 3, but also it is beneficial to shorten the length of the connecting piece between the terminal 22 and the socket, which is beneficial to reducing costs.

[0058] When assembling the charging connector plug, it is necessary to first install two metal strips 21 into the end cap 14. However, after the metal strips 21 are installed in the end cap 14, it will be impossible to weld the terminals 22. And if the metal strips 21 are welded to the terminals 22 first, the traditional integral end cap 14 cannot be installed on the metal strips 21. For this reason, the end cap 14 of this embodiment adopts a first end cap 14a and a second end cap 14b that are spliced together, and a through hole for the metal strips 21 to pass through is defined between the first end cap 14a and the second end cap 14b. In this way, after the metal strips 21 are welded to the terminals 22, the first end cap 14a and the second end cap 14b can be installed from the outside of the two metal strips 21 along the direction pointing to the metal strips 21 respectively.

[0059] To ensure the connection effect between the first end cap 14a and the second end cap 14b, in this embodiment, preferably, a connection structure is provided between the first end cap 14a and the second end cap 14b, and the connection structure is used to prevent the first end cap 14a and the second end cap 14b from separating from the splicing. Specifically, as Figure 5 shown, the connection structure includes a rib 142 provided on one of the first end cap 14a and the second end cap 14b, and a groove 143 provided on the other of the first end cap 14a and the second end cap 14b. Through the engagement of the rib 142 and the groove 143, the first end cap 14a and the second end cap 14b are spliced together.

[0060] As a preferred embodiment, still as Figure 5 shown, the projections of the rib 142 and the groove 143 on the bottom surface of the end cap 14 are both in a T shape. At this time, after the first end cap 14a and the second end cap 14b are spliced, by using the clamping fit between the T-shaped rib 142 and the groove 143, the separation of the splicing between the first end cap 14a and the second end cap 14b can be effectively prevented. It can be understood here that in addition to adopting a T-shaped structure, the rib 142 and the groove 143 can also adopt a trapezoidal structure, and this is also possible.

[0061] In addition, the structures of the first end cap 14a and the second end cap 14b in this embodiment are the same, so that the preparation molds of the end cap 14 can be reduced. And in this embodiment, connection holes 141 are provided on both the first end cap 14a and the second end cap 14b. Correspondingly, connection bosses 1121 are provided on the outer housing 11, and the connection bosses 1121 can be clamped in the connection holes 141. Thus, through the clamping fit between the connection bosses 1121 and the connection holes 141, the first end cap 14a and the second end cap 14b are clamped and connected to the outer housing 1, that is, the end cap 14 is clamped and connected to the housing 1.

[0062] In addition, the stopper 25 of this embodiment preferably adopts a split structure, that is, the stopper 25 also includes a first stopper 25a and a second stopper 25b. The first stopper 25a and the second stopper 25b can be installed from the side of the metal row 21, and avoidance holes for avoiding the metal row 21 are provided on both the first stopper 25a and the second stopper 25b. At this time, it is beneficial to the installation of the stopper 25 on the metal row 21.

[0063] In this embodiment, as a preferred implementation manner, the holding structure provided between the housing 1 and the flip cover 3 includes a holding portion provided on the housing 1 and an abutting portion provided on the flip cover 3. By abutting the abutting portion against the holding portion, the flip cover 3 is held in the open position. Refer to Figures 6 to 8 As shown, in this embodiment, a connecting lug 31 is provided on the flip cover 3, and the flip cover 3 is rotatably connected to the housing 1 through a rotating shaft 4 provided on the connecting lug 31. The abutting portion includes an extending boss 311 provided on the connecting lug 31, and an abutting end face 3111 is provided on one side of the extending boss 311. The holding portion includes an extending arm 1111 provided on the housing 1, and the extending arm 1111 is spaced from the outer surface 1110 of the housing 1.

[0064] When the flip cover 3 is switched from the covering position to the open position, the connecting lug 31 rotates relative to the housing 1, and one end of the abutting end face 3111 can press against the extending arm 1111 to deform, and the extending arm 1111 stores energy. And as the connecting lug 31 continues to rotate, one end of the abutting end face 3111 releases the pressing on the extending arm 1111. At this time, the extending arm 1111 releases energy, and the end of the extending arm 1111 abuts against the abutting end face 3111, so that the flip cover 3 is held in the open position.

[0065] In terms of the specific structure, in this embodiment, a first rotating shaft hole 310 is provided on the connecting lug 31, and a second rotating shaft hole 1112 coaxial with the first rotating shaft hole 310 is provided on the mounting seat of the housing 1. The flip cover 3 is rotatably connected to the housing 1 through a rotating shaft 4 passing through the first rotating shaft hole 310 and the second rotating shaft hole 1112, and the rotating shaft 4 is axially limited by a shaft shoulder formed at one end of itself and a snap ring 41 clamped at the other end. Among them, the projection of the first rotating shaft hole 310 on the cross-section of the rotating shaft 4 is in a semi-circular arc shape, which has a simple structure, is convenient for processing and manufacturing, and is also conducive to weight reduction design.

[0066] Moreover, to ensure the sealing performance between the flip cover 3 and the inner housing 1, in this embodiment, a second sealing ring 20 is also provided between the flip cover 3 and the inner housing 12. Specifically, a sealing groove is provided on the end face of the inner housing 1, and the second sealing ring 20 is installed in the sealing groove. When the flip cover 3 seals the end of the housing 1, the side of the second sealing ring 20 away from the inner housing 1 can abut tightly against the flip cover 3, so as to ensure the sealing performance between the flip cover 3 and the inner housing 12.

[0067] To improve the connection reliability of the flip cover 3 on the housing 1, in this embodiment, mounting holes 32 are also provided on the flip cover 3, and the flip cover 3 is connected to the inner housing 1 through a connecting member 5 passing through the mounting holes 32. Among them, the connecting member 5 can be, for example, a bolt or a stud. At this time, the connecting member 5 passes through the mounting holes 32 and is screwed into the threaded holes on the inner housing 12, so that the flip cover 3 is fixed on the housing 1. Moreover, to ensure the sealing effect of the connection between the inner housing 12 and the flip cover 3, a third sealing ring 30 is also provided in the mounting holes 32, and the third sealing ring 30 is clamped tightly on the connecting member 5.

[0068] In addition, in this embodiment, a high-voltage interlock conduction assembly is provided between the flip cover 3 and the inner housing 12. The high-voltage interlock conduction assembly includes an extension terminal 22 integrally formed on the inner housing 12 and a conduction terminal 22 snap-connected to the flip cover 3. Among them, there are two extension terminals 22 arranged at intervals. When the flip cover 3 is in the covering position, the conduction terminal 22 can abut against the two extension terminals 22 to conduct the two extension terminals 22. And when the two extension terminals 22 are in the conducting state, a large current can be allowed to flow through the metal row 21.

[0069] The charging connector plug of this embodiment can facilitate the operation of the electrical connecting member 23 to connect the terminal 22 and the socket together, thereby avoiding the influence on the installation operation of the operator due to the flip cover 3 being unable to remain in the open position, and also being beneficial to improving the use convenience of the charging connector plug and having a good use effect.
