[0046] The middle part of the connecting strip 1241 is in a rectangular hollow shape, the connecting strip 1241 is abutted with the upper and lower surfaces of the sliding block 1243 through the inner rectangular hollow part, so that the front and back sliding of the sliding block 1243 in the connecting strip 1241 can be stably realized, the sawtooth blocks 1245 are equidistantly arranged along the upper end of the connecting strip 1241, and the adjacent sawtooth blocks 1245 are arranged in an inverted triangular groove shape, so that the flexible adjustment and locking of the clamping and fixing interval can be realized through the multiple inverted triangular grooves to meet the clamping and fixing of the cable joint of a larger size.

[0047] The side of the clamping strip 12481 away from the connecting shaft 12482 is connected with the inverted triangular groove between the adjacent sawtooth blocks 1245, and the middle part of the clamping strip 12481 is rotatably connected with the inner upper end of the sleeve shell 1246 through a rotating shaft, so that the clamping strip 12481 and the inverted triangular groove can be stably clamped and locked, the pressing rod 12489 is connected with the two rectangular blocks 12483, and the pressing rod 12489 is arranged opposite to the upper end of the handle 1247, so that the pressing rod 12489 can realize the connection of the two clamping pieces 1248 and the synchronous unlocking transmission of the two clamping pieces 1248.

[0048] The working principle is as follows:

[0049] Firstly, referring to Figure 9 and Figure 10The wiring diagram shown can realize the formation of a "ring network" contactor switching structure, that is, each module in the main machine is connected through the contactor "hand in hand", and is connected at the beginning and end to form a "ring network". The operation logic of the "ring network" structure is as follows: when not charging, the connection between the modules is disconnected, when charging, the line power module is enabled, and when the line demand is not met, the idle module can be called along the "ring network" clockwise or counterclockwise to temporarily form a part of the output to meet the charging demand, so as to achieve the purpose of large power charging. In the "ring network" structure in the multi-charging scene, multiple continuous small rings can be formed to improve the charging efficiency. In this way, the one-drag-many design of the charging pile can be realized, and the extension and the main machine are decoupled. The failure of the extension will not affect the normal operation of the main machine. At the same time, the use of the "ring network" structure reduces the number of contactors used, making the power distribution more efficient, and the total output power is maximized. At the same time, the use efficiency of the module is improved, and a balance is achieved between cost and performance. This design makes the pile placement more flexible in the construction of the charging station.

[0050] When the charging cable is connected to the electrical equipment inside the cabinet, in order to keep the joint end stable, a cable installation stabilizing device 12 is arranged at the lower end of the cabinet 1. First, the cable joint end extends into the inside of the cabinet 1 from the lower end of the cabinet 1, and at the same time, the cable joint end is moved into the clasp 122 arranged at the front side of the upper end of the support 121. At this time, the worker can move the clamping plate 123 to the opposite position of the front side of the upper end of the support 121 by holding the handle 1247, so as to realize the connection between the sleeve 1246 arranged on the left and right sides of the clamping plate 123 and the butt joint strip 1241 arranged on the left and right sides of the support 121. When the sleeve 1246 is pushed onto the outside of the butt joint strip 1241, the clamping strip 12481 arranged inside the upper end of the sleeve 1246 will be in contact with the multiple sawtooth blocks 1245 arranged equidistantly on the upper end of the butt joint strip 1241. The clamping strip 12481 can be assisted by the rebound of the reset spring 12488 arranged inside the connecting cylinder 12486 to make the clamping strip 12481 move with the sleeve 1246, and the clamping strip 12481 will be intermittently locked with the inverted triangular groove formed between the adjacent rectangular blocks 12483. At the same time, when the sleeve 1246 and the butt joint strip 1241 are connected and moved on the outside, the rear push of the slider 1243 built-in the butt joint strip 1241 is realized, so that the slider 1243 moves backward through the guide rod 1242 arranged inside the butt joint strip 1241. When the slider 1243 moves backward, the spring 1244 arranged on the outer end of the guide rod 1242 is pushed and compressed. Because the clamping strip 12481 and the adjacent rectangular block 12483 are locked in the inverted triangular groove, the spring 1244 cannot rebound when it is pushed and compressed. Therefore, when the clamping plate 123 is pushed to cooperate with the clasp 122 arranged on the front side of the upper end of the support 121, the clamping and fixing of the cable joint end can be completed, so that it remains in a stable installation state, avoiding the loosening of the joint position caused by the subsequent dragging of the charging gun, and affecting the charging effect.

[0051] If the unlocking activity needs to be realized, the pressure rod 12489 arranged at the upper end of the handle 1247 is pressed down, so that the rectangular blocks 12483 on both sides of the pressure rod 12489 are simultaneously moved downward, and in the process of moving downward of the rectangular blocks 12483, the connecting shaft 12482 abutting the side edge of the rectangular blocks 12483 will cooperate with the long groove on one side of the clamping strip 12481 to conveniently realize the downward pressing and rotating lifting of the clamping strip 12481, so that the clamping strip 12481 is moved out of the inverted triangular groove, and the unlocking activity is completed. In this way, the spring 1244 arranged outside the guide rod 1242 in a compressed state can realize self-rebound pushing activity when the unlocking activity is completed, that is, the sliding block 1243 is pushed forward along the guide rod 1242 to reset, and the sleeve shell 1246 is pushed forward to conveniently complete the unlocking activity of the clamping plate 123 and the support 121. In addition, when the rectangular blocks 12483 drive the connecting shaft 12482 to lift the clamping strip 12481, the support rod 12484 inserted inside can realize stable downward pressing and guiding. Meanwhile, in the process of moving downward of the rectangular blocks 12483, the insertion rod 12485 inserted at the lower end of both sides of the rectangular blocks 12483 can simultaneously realize the downward pushing of the connecting disc 12487 arranged inside the connecting cylinder 12486, so that the connecting disc 12487 is pressed downward to press the reset spring 12488 connected at the lower end, and when the pressure rod 12489 is subsequently released, the clamping strips 12481 on both sides can realize self-resetting activity through the rebounding of the reset spring 12488, to meet the flexible clamping activity of the next position.

[0052] In addition, the inverted triangular groove clamping cooperation between the clamping strip 12481 and the multiple adjacent sawtooth blocks 1245 can meet the flexible adjustment of the locking distance, so that it can meet the clamping and fixing of a larger cable joint end, and greatly improve the use range.

[0053] The above is only a preferred example of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or replace some of the technical features with equivalent ones.
