As shown in fig. 1 and 2, the current connector 30 is provided at a rear end 102 of the device 10 fixed to the vehicle body, the electrical connection device 22 is provided at a front end 101 of the device 10 fixed to the vehicle body, and the electrical connection device 22 is connected to the current connector 30. The electrical connection means 22 may be terminals. The current connector 30 may be a DC connector or an AC connector; the cradle may include a DC connector and/or an AC connector.
In one embodiment, as shown in fig. 3 or 5, the current connector 30 includes a connection hole 311, and the detachable mechanism 40 passes through the connection hole 311. The connection hole 311 may be a circular through hole or a U-shaped slot provided on the current connector 30. The detachable mechanism 40 passes through the connecting hole 311, so as to fix the current connector 30 on the charging stand, thereby preventing the function of the charging stand from being disabled due to the movement of the current connector 30.
In one embodiment, the current connector 30 is provided with a mounting portion, and the device 10 fixed to the vehicle body is provided with a mounting hole 11, and the mounting portion is inserted into the mounting hole 11 and detachably connected. When the current connector 30 is assembled with the device 10 fixed to the vehicle body, if there is no corresponding positioning mechanism, it may take a long time for an assembly operator to assemble the current connector 30 with the device 10 fixed to the vehicle body to the installation position, and when the detachable mechanism 40 is used to fix the current connector 30 to the device 10 fixed to the vehicle body, relative positional shift may occur, resulting in assembly failure.
As shown in fig. 1, 4 and 7, the mounting portion of the current connector 30 is stepped with the body of the current connector 30, and the mounting portion is inserted into the mounting hole 11 and detachably connected to achieve positioning and matching of the current connector 30 and the device 10 fixed to the vehicle body, so as to facilitate assembly and disassembly of the current connector 30 and the device 10.
In one embodiment, the detachable mechanism 40 includes a screw 61, the electrical connection device 22 is provided with a fixing portion, a threaded hole is provided on an end surface of the fixing portion, a through hole is provided on one end of the cable 21, a hole diameter of the through hole is larger than an outer diameter of the screw 61 and smaller than an outer diameter of a connection hole 311 of the electrical connection device 22, the screw 61 is inserted into the through hole and the connection hole 311 or a U-shaped groove and is screwed with the threaded hole, so as to fix the electrical connection device 22, one end of the cable 21 and the current connector 30 on the device 10 fixed to the vehicle body. By screwing the electrical connector 22 to one end of the cable 21, the screw 61 can be removed directly to replace the electrical connector 22 when the electrical connector 22 is damaged.
Further, the end face of the threaded hole of the electrical connection device 22 is electrically connected to the side face of the cable 21. In order to conduct the charging current of the charging stand, the electrical connection device 22 is electrically connected to the cable 21 sufficiently, so that the electrical connection device 22 needs to be in contact with the cable 21 in a sufficient area, and the contact resistance at the connection point is as small as possible compared with the conductor resistance of the cable 21 itself.
Further, the outer diameter of the fixing portion is smaller than the inner diameter of the connection hole 311. Since the electrical connection device 22 and the cable 21 are respectively located at two sides of the current connector 30, if the outer diameter of the fixing portion is greater than or equal to the inner diameter of the connection hole 311, the electrical connection device 22 cannot pass through the connection hole 311 and is electrically connected to the cable 21, and the basic charging function of the charging stand cannot be realized. Therefore, the electrical connector 22 can pass through the connection hole 311 of the current connector 30 and be electrically connected to the cable 21 only if the outer diameter of the fixing portion is smaller than the inner diameter of the connection hole 311.
As shown in fig. 3 and 5, the current connector 30 includes a connection hole 311, and the detachable mechanism 40 passes through the connection hole 311. The electrical connection device 22 is received in the connection hole 311.

Further, the torque range of screwing the screw 61 into the screw hole is 0.1N · m to 30N · m.
In order to verify the torque range of the screw 61 screwed with the threaded hole and the influence on the electrical connection performance of the electrical connection device 22 and the cable 21, the inventor selects the same electrical connection device 22, the same current connector 30, the same screw 61 and the same cable 21, screws the same electrical connection device 22, the same current connector 30, the same screw 61 and the same cable 21 together by adopting different torques, and respectively tests the contact resistance of the electrical connection device 22 and the cable 21 and the connection condition of the electrical connection device 22 and the cable 21 after a vibration test. The test results are shown in table 1.
The contact resistance between the electrical connection device 22 and the cable 21 is measured by using a micro-resistance measuring instrument, placing one end of a measuring end of the micro-resistance measuring instrument on the cable 21 and the other end of the measuring end on the electrical connection device 22, and reading the contact resistance reading on the micro-resistance measuring instrument after the same position is placed for each measurement. In this example, a contact resistance of more than 1m Ω is not acceptable.
The vibration test is that the connected sample piece is placed on a vibration test bed and passes through 300 vibration cycles, each cycle needs 6 directions of vibration, the frequency is 100Hz, and the unidirectional acceleration is 40m/s2Then, it is observed whether the electrical connection device 22 and the cable 21 are loosened. In the present embodiment, the electrical connection device 22 is not damaged when being released or installed from the cable 21And (4) passing.
Table 1, effect of different torques on contact resistance and connection condition:
as can be seen from table 1 above, when the torque value of screwing the screw 61 into the screw hole is less than 0.1N · m, the contact resistance value of the electrical connection device 22 and the cable 21 is not good, and the electrical connection device 22 and the cable 21 are loosened after the vibration test, and therefore, the minimum value of the torque range of screwing the screw 61 into the screw hole is set to 0.1Nm by the inventors. When the torque value of the screw 61 screwed with the screw hole is greater than 30N · m, the torque applied to the cable 21, the current connector 30 and the electrical connection device 22 is too large due to the excessive torque, so that the plastic current connector 30 is damaged by a large pressure, and the basic function of the charging stand cannot be realized. Therefore, the inventors determined the torque range in which the screw 61 is screwed into the screw hole to be 0.1N · m to 30N · m.
In one embodiment, the number of screws 61 is preferably 2-36. In the charging stand, the current connector 30 may be a DC connector or an AC connector, and regardless of the DC connector or the AC connector, the charging stand includes two main charging cables 21 and two corresponding electrical connection devices 22, which mainly conduct a large charging current, and generally, the diameter of the charging cable 21 is 60mm2-260mm2And other lines are low-voltage control cables, so that the current is small, and the wire diameter range of the cable 21 is also small. In the use of charging seat, play the electric connection device 22 who switches on charging current, the probability of damage is greater than the electric connection device 22 on the little low-voltage control cable of switching on current far away, consequently only need set up two electric connection device 22 that play charging current into screw structure's detachable construction, and saving cost that can be bigger makes things convenient for the maintenance of charging seat. Preferably, when the charging stand comprises a DC connector and an AC connector, there can be 36 electric connection devices 22, and the electric connection devices 22 can be all arranged as a detachable mechanism with a screw structure, no matter which loop of the charging stand is damaged, the detachable mechanism can be usedCarry out quick change, save maintenance duration, reduce cost of maintenance.
