Each ceramic ball limiter is set in a corresponding ball limiter groove, and each ceramic ball is slidably connected to the corresponding ball limiter groove, and each ceramic ball is slidably connected to the concave limiter ring groove.

[0040] See also Figures 1 to 3 In order to better understand the quick-plug connection structure 10 for the adapter cable disclosed in the present invention, the quick-plug connection structure 10 for the adapter cable is further explained below:

[0041] A quick plug-in connection structure 10 for an adapter cable in one embodiment includes a first connector 100 and a second connector 200. The connection end of the first connector 100 and the connection end of the second connector 200 are respectively used to communicate with the corresponding adapter cable, and the plug-in end of the first connector 100 is movably plugged with the plug-in end of the second connector 200. An inner concave limiting ring groove 102 is provided on the peripheral edge of the side wall of the plug-in end of the first connector 100, and a first annular support block 110 is provided on the peripheral edge of the side wall of the plug-in end of the first connector 100; a plurality of ball limiting grooves 202 are provided on the peripheral edge of the side wall of the plug-in end of the second connector 200. The quick-plug connection structure 10 also includes an elastic locking component 300, which includes a sliding shell 310, an elastic member 320 and a plurality of ceramic balls 330. The sliding shell 310 is sleeved on the first connecting member 100. An inlay groove 3102 is formed on the inner wall of the sliding shell 310. A second annular support block 3110 is provided on the inner wall of the sliding shell 310. One end of the elastic member 320 is inlaid in the inlay groove 3102 and abuts against one side of the first annular support block 110. The other end of the elastic member 320 abuts against one side of the second annular support block 3110 so that the sliding shell 310 is slidably connected to the first connecting member 100. Each ceramic ball 330 is limited in a corresponding ball limiting groove 202. Each ceramic ball 330 is slidably connected to the corresponding ball limiting groove 202. Each ceramic ball 330 is slidably connected to the concave limiting ring groove 102.

[0042] In this embodiment, when the first connector 100 and the second connector 200 are plugged and assembled, each ceramic ball 330 slides on the side wall of the plug-in end of the first connector 100 to the concave limiting ring groove 102 and is limited in the concave limiting ring groove 102, so that the first connector 100 and the second connector 200 can be locked and fixed, thereby effectively ensuring that the quick-plug connection structure 10 for the adapter cable has better connection stability.

[0043] Furthermore, when disassembling the first connector 100 and the second connector 200, it is only necessary to slide the sliding sleeve 310 toward the end away from the second connector 200, so that the second annular support block 3110 slides and squeezes the elastic member 320 while driving the first connector 100 to slide toward the end away from the second connector 200. In this way, each ceramic ball 330 can be pulled out into the concave limiting ring groove 102, so that the first connector 100 and the second connector 200 can be quickly disengaged, thereby realizing the quick plugging and unplugging of the adapter cable.

[0044] It should be noted that since the ball limit groove 202 is a through groove, and each ceramic ball 330 is movable in the corresponding ball limit groove 202, that is, it can roll and will not escape from the ball limit groove 202, when the ceramic ball 330 slides on the first connecting member 100, it will be squeezed by the first connecting member 100, so that the ceramic ball 330 is squeezed and moved toward the end of the ball limit groove 202 away from the first connecting member 100. When the ceramic ball 330 slides to the concave limiting ring groove 102, the reaction force of the inner wall of the ball limit groove 202 of the first connecting member 100 causes the ceramic ball 330 to return to its original position and abut against the concave limiting ring groove 102. At this time, a clicking sound can be heard, which means that the first connecting member 100 and the second connecting member 200 are locked by the ceramic ball 330. Similarly, when the first connecting member 100 and the second connecting member 200 are disengaged, it is only necessary to slide the sliding sleeve 310 toward the end away from the second connecting member 200, so that the second annular support block 3110 slides and squeezes the elastic member 320 while driving the first connecting member 100 to slide toward the end away from the second connecting member 200. At this time, the ceramic ball 330 is squeezed by the concave limiting ring groove 102 when the first connecting member 100 slides, so that the ceramic ball 330 is squeezed and moved toward the end of the ball limiting groove 202 away from the first connecting member 100, so that the ceramic ball 330 can be disengaged from the concave limiting ring groove 102, and after the first connecting member 100 and the second connecting member 200 are completely disengaged, the reaction force of the inner wall of the ball limiting groove 202 of the first connecting member 100 causes the ceramic ball 330 to return to its original position, so that the quick plug-in and pull-out of the quick-plug connection structure 10 of the adapter cable can be achieved.

[0045] It should be noted that the elastic member 320 is a spring, and the ceramic ball 330 is made of ceramic material, which has wear-resistant and insulating properties, so that the ceramic ball 330 has a good service life and good safety performance, thereby effectively improving the service life and safety performance of the quick-plug connection structure 10 of the adapter cable.

[0046] like Figure 2 , Figure 4 and Figure 7 As shown, in one embodiment, the first connector 100 includes a first housing 120 and a first connector 130, the first housing 120 is provided with a first position-limiting installation slot 1202, the first connector 130 is arranged in the first position-limiting installation slot 1202, the side wall periphery of one end of the first housing 120 is provided with an inner concave position-limiting ring groove 102, and the side wall periphery of the first housing 120 is provided with a first annular support block 110. It can be understood that the first housing 120 functions to protect the first connector 130 and is adapted to be connected with the second housing 210 of the second connector 200, so as to ensure good connection stability between the first connector 100 and the second connector 200.

[0047] like Figure 7 As shown, in one embodiment, the inner wall of the first limiting installation groove 1202 is provided with a first limiting ring groove 1204. The first connector 100 further includes a first gasket block 140, which is inlaid in the first limiting ring groove 1204, and the first connector 130 abuts against the first gasket block 140, so that the first connector 130 is fixed in the first housing 120, and the connection end of the first connector 130 is passed through the hollow area of ​​the first gasket block 140. It can be understood that a limited area is formed by the first gasket block 140 and the inner wall of the first shell 120, and a partial structure of the first connector 130 is limited and fixed in the limited area, so that the first connector 130 is fixedly connected to the first shell 120. Since the first limited mounting groove 1202 is hollow, that is to say, the connection end of the first connector 130 is connected to the adapter harness arranged in the first limited mounting groove 1202, thereby realizing electrical conduction between the first connector 130 and the adapter harness.

[0048] like Figure 2 , Figure 5 and Figure 8As shown, in one embodiment, the second connector 200 includes a second housing 210 and a second connector 220, the second housing 210 is provided with a second position-limiting installation slot 2102, the second connector 220 is arranged in the second position-limiting installation slot 2102, and the first connector 130 is movably connected with the second connector 220. It can be understood that the second housing 210 is used to protect the second connector 220 and to be matched and connected with the first housing 120 of the first connector 100, so as to ensure good connection stability between the first connector 100 and the second connector 200.

[0049] like Figure 8 As shown, in one embodiment, the inner wall of the second limiting installation groove 2102 is provided with a second limiting ring groove 2104. The second connector 200 further includes a second gasket block 230, which is inlaid in the second limiting ring groove 2104, and the second connector 220 abuts against the second gasket block 230, so that the second connector 220 fixes the connection end of the second connector 220 and passes through the hollow area of ​​the second gasket block 230. It can be understood that a limited area is formed by the second gasket block 230 and the inner wall of the second shell 210, and a part of the structure of the second connector 220 is limited and fixed in the limited area, so that the second connector 220 is fixedly connected to the second shell 210. Since the second limiting installation groove 2102 is hollow, that is to say, the connection end of the second connector 220 is connected to the adapter harness arranged in the first limiting installation groove 1202, so as to realize electrical conduction between the second connector 220 and the adapter harness.

[0050] like Figure 4 As shown, in one embodiment, a plurality of plug slots 1302 are provided at the plug end of the first connector 130. The first connector 130 is provided with a plurality of connection pins 1310, and each connection pin 1310 is disposed in a corresponding plug slot 1302. It can be understood that the connection pin 1310 is a PIN pin, which can achieve electrical conduction between the first connector 130 and the second connector 220.

It can be understood that the plug-in block 2210 is adapted to the plug-in slot 1302, and the connection conductive slot 2212 is adapted to the connection pin 1310, so that the first connector 130 and the second connector 220 can be ensured to have a better connection stability.

[0052] It should be noted that the inner wall structure of the connecting conductive groove 2212 of the plug block 2210 is a metal conductive structure, so that it can form electrical conduction with the connecting pin 1310.

[0053] like Figure 4 and Figure 5 As shown, in one embodiment, the first shell 120 and the second shell 210 are both insulating plastic shells. It is understandable that the first shell 120 and the second shell 210 are both insulating plastic shells, which can ensure the safety of the quick-plug connection structure 10 when in use.

[0054] like Figure 7 and Figure 8 As shown, in one embodiment, the first gasket block 140 and the second gasket block 230 are both insulating plastic gasket blocks. It is understandable that the first gasket block 140 and the second gasket block 230 are both insulating plastic gasket blocks, which can ensure the safety of the quick-plug connection structure 10 when in use.

[0055] The present disclosure also provides a new energy vehicle fast charging adapter cable, including the quick-plug connection structure for the adapter cable described in any of the above embodiments.

[0056] In this embodiment, when the first connecting member and the second connecting member are plugged and assembled, each ceramic ball slides to the concave limiting ring groove on the side wall of the plug-in end of the first connecting member and is limited in the concave limiting ring groove, so that the first connecting member and the second connecting member can be locked and fixed, which can effectively ensure that the new energy vehicle fast charging adapter has good connection stability.

[0057] Furthermore, when disassembling the first connecting member and the second connecting member, it is only necessary to slide the sliding sleeve toward the end away from the second connecting member, so that the second annular support block slides to squeeze the elastic member while driving the first connecting member to slide toward the end away from the second connecting member. In this way, each ceramic ball can be pulled out into the concave limiting ring groove, so that the first connecting member and the second connecting member can be quickly disengaged, thereby realizing the rapid plugging and unplugging of the new energy vehicle fast charging adapter cable.

[0058] Compared with the prior art, the present invention has at least the following advantages:

[0059] 1. When the first connector and the second connector are plugged and assembled, each ceramic ball slides on the side wall of the plug-in end of the first connector to the concave limiting ring groove and is limited in the concave limiting ring groove, so that the first connector and the second connector can be locked and fixed, which can effectively ensure that the quick-plug connection structure for the adapter cable has good connection stability.

When disassembling the first connecting member and the second connecting member, it is only necessary to slide the sliding sleeve toward the end away from the second connecting member, so that the second annular support block slides to squeeze the elastic member while driving the first connecting member to slide toward the end away from the second connecting member. In this way, each ceramic ball can be pulled out to the concave limiting ring groove, so that the first connecting member and the second connecting member can be quickly disengaged, thereby realizing the quick plugging and unplugging of the adapter cable.

[0061] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent.
