Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 3, the flexible connection mechanism for the explosion-proof automatic charging plug and cable comprises an insulating terminal 1, a locking screw 2, a connection screw 3, a main shell 4, an insulating guide terminal 5, a cable 6, a rubber ring 7, a steel gasket 8, a wire nozzle 9, an explosion-proof copper column 10, a compression spring 11, a connection copper column 12 and a jackscrew 13.
The main casing body 4 is the major structure spare of this coupling mechanism, and thinner one end is used for inserting cable 6 and locks it, and thicker one end is used for fixed flame proof copper post 10, rubber ring 7, steel packing ring 8 and line mouth 9 are installed and are used for flame proof and locking cable in the inboard of the thinner one end of main casing body 4. The cable 6 extends into the thinner end of the main shell 4 and passes through the wire nozzle 9, the steel gasket 8 and the rubber ring 7, and the wire nozzle 9 is screwed in the main shell 4 to enable the rubber ring 7 to be elastically deformed so as to compress the cable 6. Reserve a section space in main casing 4 middle section as the explosion-proof shell, will be located this section cable 6 and peel off outer glue film, expose 4 cable conductor 14, 4 cable conductor 14 twines into the heliciform, and 4 cable conductor 14 are pegged graft respectively in the one end of 4 connection copper posts 12 to compress tightly fixedly with jackscrew 13.
The other ends of the 4 connecting copper columns 12 penetrate through the insulating guide terminals 5 respectively, are screwed on the 4 explosion-proof copper columns 10, and are arranged in the insulating terminal 1 together. The explosion-proof copper column 10 and the connecting copper column 12 are sleeved with a compression spring 11, and the explosion-proof copper column 10 and the connecting copper column 12 can reciprocate by the jacking pressure of the compression spring 11. The connecting screw 3 connects and fixes the insulated guide terminal 5 and the insulated terminal 1 together to form a connecting assembly, and the locking screw 2 fixes the connecting assembly in the main housing 4.
4 explosion proof copper posts 10 are installed in main casing 4 with the circumference form equipartition, and 4 locking screw 2 are fixed with insulating terminal 1 and insulating direction terminal 5 with the circumference form equipartition.
The utility model discloses a working process is:
when the robot is performing the autonomous charging operation, first the robot moves to the charging pile position. Explosion-proof automatic charging plug cable flexible connection mechanism, charging plug promptly fills under electric pile power effect, whole forward motion, until explosion-proof copper post 10 contacts the copper electrode of robot charging socket, two of 4 explosion-proof copper posts 10 hit in place and detected the copper post and put through control circuit this moment, control system sends operating instruction, continue to operate charging plug and move appointed displacement 3mm forward, make explosion-proof copper post 10 inwards slide along the axial in insulating terminal 1, compressed compression spring 11 after, stopped in appointed displacement 3mm department. At this time, all the 4 flameproof copper columns 10 are pressed on the copper electrode of the socket through the elastic force of the compression spring 11, and the robot starts to execute automatic charging operation. After the robot finishes charging, the charging plug exits from the socket, and the explosion-proof copper column 10 automatically rebounds and resets under the action of the compression spring 11. In the compression and rebound processes, the connecting copper column 12 drives the cable core 14 to do telescopic motion in the explosion-proof shell, and due to the existence of the winding spiral, the cable core 14 is not stretched and pulled directly by external force, so that the flexible connection effect is achieved, and the long-term safe and stable work can be realized.
