[0038] See also Figures 1 to 7 This embodiment provides an electric motorcycle connector assembly that can be used for, but is not limited to, charging electric motorcycles. The electric motorcycle connector assembly includes an electric motorcycle plug 1 and an electric motorcycle socket 2. The electric motorcycle plug 1 is configured on the battery pack, and the electric motorcycle socket 2 is configured on the charging cabinet. For example, the electric motorcycle plug 1 is configured on the charging pack of the electric motorcycle. By plugging the electric motorcycle plug 1 into the electric motorcycle socket 2, the electric motorcycle can be charged.
[0039] See also Figures 1 to 3 The electric motorcycle plug 1 includes a plug body 11, a plug terminal 12 and a plug glue 13. The plug body 11 is provided with a first terminal receiving hole 111 and a first glue groove 112. The first glue groove 112 is provided at the end of the first terminal receiving hole 111 and is connected to the first terminal receiving hole 111; the head of the plug terminal 12 passes through the first glue groove 112 and is riveted into the first terminal receiving hole 111; the plug glue 13 is poured between the first glue groove 112 and the peripheral wall of the plug terminal 12 to form a plug bonding layer. The plug bonding layer can greatly enhance the plug-in retention force of the plug terminal 12 and the sealing function of the electric motorcycle plug 1, prevent the PIN from being withdrawn when the electric motorcycle plug 1 and the electric motorcycle socket 2 are plugged in and out, and improve the stability and reliability of the connection. The plug bonding layer not only enhances the plug-in retention force, but also plays a good sealing role. It can fill the tiny gap between the plug terminal 12 and the first terminal receiving hole 111, preventing water, dust or other contaminants from entering the interior of the connector, thereby protecting the internal electrical components from damage.
[0040] See also Figures 4 to 7 The electric motorcycle socket 2 includes a socket body 21, a socket terminal 22 and a socket glue 23. The socket body 21 is provided with a second terminal receiving hole 211 and a second glue groove 212. The second glue groove 212 is provided at the end of the second terminal receiving hole 211 and is connected to the second terminal receiving hole 211. The head of the socket terminal 22 passes through the second glue groove 212 and is riveted into the second terminal receiving hole 211. The head of the socket terminal 22 has a connection end hole 221 electrically connected to the plug terminal 12 of the electric motorcycle plug 1. The socket glue 23 is poured between the second glue groove 212 and the surrounding wall of the socket terminal 22 to form a socket adhesive layer. The socket adhesive layer can greatly enhance the plug-in retention force of the plug terminal 12 and the sealing function of the electric motorcycle socket 2, prevent the PIN back problem when the electric motorcycle plug 1 and the electric motorcycle socket 2 are plugged in and out, and improve the stability and reliability of the connection. The socket adhesive layer not only enhances the plug-in retention force, but also plays a good sealing role. It can fill the tiny gap between the socket terminal 22 and the second terminal receiving hole 211 to prevent water, dust or other pollutants from entering the interior of the connector, thereby protecting the internal electrical components from damage.
[0041] Specifically, when the electric motorcycle plug 1 is docked to the electric motorcycle socket 2, the head of the plug terminal 12 is inserted into the connecting end hole 221 of the socket terminal 22, thereby realizing the electrical connection between the electric motorcycle plug 1 and the electric motorcycle socket 2.
[0042] See also Figures 1 to 3 The electric motorcycle plug 1 also includes a floating bushing 14. A bushing limiting hole 113 is provided on the plug body 11. The floating bushing 14 is used to install the plug body 11. The floating bushing 14 is arranged in the bushing limiting hole 113, and the peripheral wall of the floating bushing 14 is spaced apart from the hole wall of the bushing limiting hole 113.
[0043] In the present invention, the floating bushing 14 is connected to the battery pack, so that the plug body 11 is limited and installed on the battery pack through the floating bushing 14. Since the peripheral wall of the floating bushing 14 and the hole wall of the bushing limiting hole 113 are spaced apart, that is, there is a gap between the peripheral wall of the floating bushing 14 and the hole wall of the bushing limiting hole 113, the plug body 11 can float on the XY plane relative to the floating bushing 14. Specifically, when the electric motorcycle plug 1 is docked to the electric motorcycle socket 2, when the electric motorcycle plug 1 and the connecting end hole 221 appear single During the squeezing and friction, the plug body 11 can float accordingly. For example, when the electric motorcycle plug 1 is squeezed and rubbed against the left side of the connection end hole 221, the plug body 11 can float to the right, reducing the friction of the left side, so that the right side of the connection end hole 221 can also make frictional contact with the electric motorcycle plug 1. For another example, when the electric motorcycle plug 1 is squeezed and rubbed against the upper side of the connection end hole 221, the plug body 11 can float downward, reducing the friction of the upper side, so that the lower side of the connection end hole 221 can also make frictional contact with the electric motorcycle plug 1. The electric motorcycle plug 1 provided by the present technical solution enables the electric motorcycle plug 1 to be in uniform contact with the inner wall of the connection end hole 221, reducing the unilateral squeezing friction during electrical connection, and solving the technical problems in the prior art of the electric motorcycle plug 1 being easily heated and causing electric sparks when plugged into the electric motorcycle socket 2, as well as the technical problem of screw displacement during customer installation.
[0044] In some specific embodiments, the plug body 11 can float by 1 mm in both the X and Y directions on the XY plane, that is, the plug body 11 can move 1 mm to the left or 1 mm to the right; the plug body 11 can move 1 mm downward or 1 mm upward.
[0045] See also Figure 3 In one embodiment, the floating bushing 14 includes a column portion 141, a first anti-slip portion 142 and a second anti-slip portion 143. The column portion 141 is arranged in the bushing limiting hole 113, and the peripheral wall of the column portion 141 is spaced apart from the hole wall of the bushing limiting hole 113, so that the plug body 11 can float relative to the floating bushing 14. The first anti-slip portion 142 and the second anti-slip portion 143 are respectively connected to the two ends of the column portion 141. The first anti-slip portion 142 and the second anti-slip portion 143 are respectively located on both sides of the plug body 11. The first anti-slip portion 142 is used to limit the plug body 11 to prevent the plug body 11 from separating from the column portion 141.
[0046] Specifically, when the plug body 11 is restricted on the charging pack by the cooperation of the column portion 141 and the first anti-detachment portion 142, the first anti-detachment portion 142 is located on the side of the plug body 11 away from the charging pack, thereby restricting the plug body 11 on the column portion 141, preventing the plug body 11 from detaching from the column portion 141, and realizing stable installation of the floating bushing 14 on the plug body 11.
[0047] See also Figure 3 In some specific embodiments, the column portion 141 is formed with a mounting hole 1411, and a fixing part such as a screw is passed through the mounting hole 1411 to connect with the charging pack, thereby achieving the installation of the plug body 11 on the charging pack through the floating bushing 14, and then restricting the installation of the electric motorcycle plug 1 on the charging pack.
[0048] In some specific embodiments, bushing retaining holes 113 are formed in the middle of opposite ends of the mounting panel of the plug body 11. Two floating bushings 14 are provided, and the two floating bushings 14 are disposed in a one-to-one correspondence between the two bushing retaining holes 113. The provision of the bushing retaining holes 113 and the floating bushings 14 facilitates installation of the plug body 11 and also stabilizes the displacement of the plug body 11 in the event of unilateral friction.
[0049] See also Figure 2 、 Figure 3 In one embodiment, the end of the plug terminal 12 protrudes a first glue dispensing groove 112 and is provided with a first welding portion 121 for welding the cable. The first welding portion 121 is a hollow semi-cylindrical structure. The first welding portion 121 of the hollow semi-cylindrical structure provides a larger welding area, making the welding operation more convenient and stable, and can be more easily welded to the cable, thereby improving the efficiency and reliability of welding.
[0050] See also Figures 5 to 7 In one embodiment, the end of the socket terminal 22 protrudes a second glue dispensing groove 212 and is provided with a second welding portion 222 for welding the cable. The second welding portion 222 is a hollow semi-cylindrical structure. The second welding portion 222 of the hollow semi-cylindrical structure provides a larger welding area, making the welding operation more convenient and stable, and can be more easily welded to the cable, thereby improving the efficiency and reliability of welding.
[0051] See also Figures 1 to 6 In one embodiment, the plug body 11 is formed with a raised protrusion 114, and the first terminal receiving hole 111 is provided on the raised protrusion 114. In one embodiment, the socket body 21 is formed with a raised enclosure 213, which surrounds the socket terminal 22 and protects the socket terminal 22. When the electric motorcycle plug 1 is docked with the electric motorcycle socket 2, the raised protrusion 114 is inserted into the enclosure 213, and the enclosure 213 restricts the circumference of the raised protrusion 114, thereby maintaining a stable docking state between the plug terminal 12 and the socket terminal 22.
[0052] See also Figures 1 to 3In one embodiment, a first sealing ring 15 is provided around the wall of the convex portion 114. When the convex portion 114 is inserted into the enclosure 213, the first sealing ring 15 is sandwiched between the convex portion 114 and the inner wall of the enclosure 213, thereby sealing the connection between the convex portion 114 and the enclosure 213 and achieving sealing around the periphery of all terminals.
[0053] See also Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 In one embodiment, a second sealing ring 16 is provided at the rear of the mounting panel of the plug body 11, surrounding the plug terminals 12. A third sealing ring 24 is provided at the rear of the mounting panel of the socket body 21, surrounding the socket terminals 22. The provision of the second sealing ring 16 and the third sealing ring 24 significantly enhances the sealing between the plug body 11 and the charging pack, and between the socket body 21 and the charging cabinet. This effectively prevents water, dust, and other contaminants from entering the connector, thereby protecting the internal electrical components from damage and ensuring the stability and reliability of the electrical connection.
[0054] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 In some specific embodiments, the plug terminal 12 includes a plug power terminal 12a, a plug ground terminal 12b, and a plug signal terminal 12c.
