DETAILED DESCRIPTION

[0034] The application will now be described in further detail, by way of example, with reference to the accompanying drawings. These drawings are very simplified schematic illustrations, which only show the basic structure of the application in a schematic manner, and therefore only show the components relevant to the application.

[0035] The energy storage single-core fast charging plug, please refer to Figures 1-8 As shown, it comprises a front cover 100, a rear cover 200 and a female terminal 500, the front cover 100 and the rear cover 200 are assembled, and the female terminal 500 is assembled in the front cover 100 and the rear cover 200.

[0036] The front cover 100 is provided with a mounting cavity 101, and a hollow sleeve 110 is arranged in the mounting cavity 101, and the front end of the female terminal 500 is inserted into the sleeve 110;

[0037] The front cover 100 is provided with a self-locking assembly 300, which comprises an outer cover 310, a lock catch 320 and an elastic piece 330, the lock catch 320 is installed in the front cover 100, the front end of the lock catch 320 is exposed to the outer cover 310, the rear end of the lock catch 320 is provided with a catch part 321, and the catch part 321 is provided with a guide surface 3211;

[0038] The catch part 321 moves in the direction of entering the mounting cavity 101 and leaving the mounting cavity 101, so as to realize the switching of the locking state and the unlocking state.

[0039] Specifically, the energy storage single-core plug of this utility model is used in conjunction with a socket (not shown in the figure). The socket and the front end of the energy storage single-core plug are inserted into each other, and the socket is partially inserted into the mounting cavity 101 at the front end of the energy storage single-core plug. The energy storage single-core plug and the socket are locked together by the buckle 321.

[0040] Furthermore, the guide surface 3211 is inclined or arc-shaped in the axial and radial directions;

[0041] When the buckle 321 protrudes from the mounting cavity 101, the guide surface 3211 also protrudes from the mounting cavity 101.

[0042] like Figure 2 and Figure 3 As shown, Figure 2 The socket and the energy storage single-core plug are not yet assembled. The latch 320 is held in the locked position under the elastic force of the elastic element 330. The elastic force of the elastic element 330 is to the left. At this time, the latch 321 protrudes into the mounting cavity 101, and the guide surface 3211 protrudes into the mounting cavity 101.

[0043] During the insertion of the socket and the energy storage single-core plug, the socket sleeve enters the mounting cavity 101. As the sleeve inserts into the mounting cavity 101, it abuts against the guide surface 3211. Figure 4 As shown, under the guidance of the guide surface 3211, during the process of inserting the sleeve into the mounting cavity 101, the guide surface 3211 pushes the buckle 321 to move to the right, causing the buckle 321 to leave the mounting cavity 101.

[0044] like Figure 3 As shown, after the socket and the energy storage single-core plug are assembled, under the action of the elastic element 330, the latch 320 moves to the left, and the latch 321 protrudes out of the mounting cavity 101 again, locking the socket and the energy storage single-core plug.

[0045] It is worth noting that the socket body should be provided with a reverse buckle that cooperates with the buckle 321. When the socket and the energy storage single-core plug are in the locked state, the buckle 321 and the reverse buckle abut against each other in the axial direction, so that the socket and the energy storage single-core plug are locked together.

[0046] When the socket and the single-core plug for energy storage need to be removed, such as Figure 5 As shown, by using a tool to push the latch 320 inward, that is... Figure 4 Move the middle to the right so that the buckle 321 leaves the mounting cavity 101, unlocking the socket and the energy storage single-core plug, and the socket and the energy storage single-core plug can be separated.

[0047] Here, tools can refer to pins, etc.

[0048] like Figure 3and Figure 5 As shown, a cavity 102 for mounting with a latch 320 is formed within the front cover 100. The cavity 102 communicates with the mounting cavity 101, as shown. Figure 3 As shown, with Figure 3 In terms of orientation, cavity 102 is located above mounting cavity 101;

[0049] The latch 320 moves radially linearly within the front cover 100, such as... Figure 4 As shown, with Figure 4 In terms of orientation, the radial direction refers to the horizontal direction from left to right, while the axial direction refers to the direction perpendicular to the plane of the paper from the inside to the outside.

[0050] Furthermore, such as Figure 3 As shown, the elastic element 330 is a spring, and the rear end of the latch 320 forms a groove 3212 for receiving the spring. One end of the elastic element 330 is limited in the groove 3212, and the other end is supported on the inner wall of the cavity 102.

[0051] Furthermore, such as Figure 5 and Figure 7 As shown, the front cover 100 is provided with a mounting hole 120, and the outer cover 310 is fitted into the mounting hole 120 and exposed on the surface of the front cover 100. The outer cover 310 is provided with a hole 311 for the front end of the latch 320 to be exposed. The outer cover 310 and the front cover 100 are assembled by a snap-fit ​​method.

[0052] Specifically, the front cover 100 is provided with a snap hole, and the outer cover 310 is provided with a snap fastener. During assembly, the outer cover 310 is pushed into the mounting hole 120, and the snap fastener is engaged with the snap hole, so that the outer cover 310 is fixedly installed on the front cover 100.

[0053] In one implementation, such as Figure 7 and Figure 8 As shown, a gear 400 is fitted around the sleeve 110, and the gear 400 can rotate around the sleeve 110; an installation gap is formed between the outer wall of the gear 400 and the inner wall of the mounting cavity 101; and a ring 410 is connected to the end of the gear 400.

[0054] The front end of the female terminal 500 is exposed in the sleeve 110, and the ring 410 is also sleeved in the sleeve 110.

[0055] In one embodiment, an inner buckle 210 and a waterproof ring 220 are installed inside the rear cover 200, and the inner buckle 210, the waterproof ring 220 and the female terminal 500 are coaxially distributed.

[0056] Furthermore, the front cover 100 and the rear cover 200 are threaded together.

[0057] Continue as Figures 7-8As shown, the rear cover 200 is in the shape of a sleeve, and the front end of the rear cover 200 is provided with an internal thread, and the end is formed with a hole into which a cable is inserted and connected to the rear end of the female terminal 500, the front cover 100 is provided with an external nut, the front cover 100 and the rear cover 200 are threadedly connected, and a sealing ring is arranged between the two.

[0058] As shown, Figure 6 The waterproof ring 220 is installed in the rear cover 200 and located at the end of the rear cover 200, and the waterproof ring 220 is mainly closed with the cable to prevent water, dust and the like from entering the rear cover 200.

[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
