DETAILED DESCRIPTION
[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of the utility model.
[0021] Please refer to Figures 1 to 8 The utility model provides a kind of technical scheme: a kind of outdoor vacuum circuit breaker of quick wiring, including circuit breaker body 1, multiple solid seal pole 2 being installed on circuit breaker body 1, and wiring terminal 3 being provided solid seal pole 2 top, wiring terminal 3 one end is equipped with positioning column 5, positioning column 5 is used to limit the outside copper nose, the outside of wiring terminal 3 is threadedly connected with driving sleeve 8, when wiring, outside copper nose is aligned positioning column 5, make copper nose and wiring terminal 3 close, then rotate driving sleeve 8 and make driving sleeve 8 movement, driving sleeve 8 drives transmission ring 13 movement, transmission ring 13 promotes first stop ring 12 and makes abutment sleeve 7 movement, abutment sleeve 7 movement to copper nose and the outside of wiring terminal 3, limit it, make copper nose unable to separate from wiring terminal 3, with the movement of abutment sleeve 7, gradually abut copper nose of protruding portion 11, apply pressure to copper nose, make copper nose and wiring terminal 3 firmly close, i.e. it can complete wiring, one end of driving sleeve 8 is rotatably installed with abutment sleeve 7, abutment sleeve 7 is slidably installed on the outside of wiring terminal 3, square groove 4 is formed on the side of abutment sleeve 7 away from driving sleeve 8, the width of square groove 4 is equal to the width of one end of wiring terminal 3, wiring terminal 3 can limit abutment sleeve 7, so that abutment sleeve 7 cannot rotate, can only occur translational motion, the inner side wall of square groove 4 is extended downward and forms protruding portion 11, one side of protruding portion 11 is equipped with inclined plane, and protruding portion 11 is used to apply downward pressure to copper nose, so that there is appropriate contact pressure between copper nose and wiring terminal 3, to ensure that copper nose and wiring terminal 3 are in good contact, to avoid poor contact.
[0022] Wherein, one side of square groove 4 is equipped with chamfer 6, when outside copper nose is connected with one end of wiring terminal 3, chamfer 6 can guide abutment sleeve 7, so that abutment sleeve 7 is more easily moved to the outside of outside copper nose and wiring terminal 3.
[0023] Wherein, the inner side wall of abutment sleeve 7 is respectively equipped with first stop ring 12 and second stop ring 14, and connecting groove 16 is formed between first stop ring 12 and second stop ring 14; one end of driving sleeve 8 is integrally formed with transmission ring 13, and transmission ring 13 is rotatably installed in connecting groove 16, so that when transmission ring 13 rotates, transmission ring 13 cannot drive abutment sleeve 7 to rotate, and when transmission ring 13 moves translationally, transmission ring 13 can drive abutment sleeve 7 to move by first stop ring 12 or second stop ring 14.
[0024] Wherein, the outside of driving sleeve 8 is uniformly provided with a plurality of anti-skid strips 9 in the circumferential direction, and the anti-skid strips 9 are used to increase the friction force, so that slippage does not easily occur when rotating the driving sleeve 8.
[0025] The outer side of the terminal 3 is provided with an external thread 15, and the inner side wall of the driving sleeve 8 is provided with an internal thread 10 matched with the external thread 15, so that the driving sleeve 8 is threadedly connected with the terminal 3 through the internal thread 10 and the external thread 15.
[0026] Specifically, when wiring, the hole position on the external copper nose is aligned with the positioning column 5, the copper nose is tightly attached to the terminal 3, and then the driving sleeve 8 is rotated. Since the driving sleeve 8 is threadedly connected with the terminal 3, the driving sleeve 8 will move, so that the driving sleeve 8 moves towards the abutting sleeve 7. The driving sleeve 8 drives the transmission ring 13 to rotate and move, and the transmission ring 13 cannot drive the abutting sleeve 7 to rotate. The transmission ring 13 drives the first blocking ring 12 to move the abutting sleeve 7. The abutting sleeve 7 moves to the outer side of the copper nose and the terminal 3, and limits the copper nose from being separated from the terminal 3. At this time, the copper nose has contacted the terminal 3 under the limiting action of the square groove 4. With the movement of the abutting sleeve 7, the protruding part 11 gradually approaches and abuts against the copper nose, and applies downward pressure to the copper nose. Until the protruding part 11 is blocked by the copper nose and cannot move, at this time, there is appropriate contact pressure between the copper nose and the terminal 3, so as to ensure that the copper nose is in good contact with the terminal 3, and the wiring is completed. When disassembling, the driving sleeve 8 is rotated, so that the driving sleeve 8 moves away from the abutting sleeve 7. The driving sleeve 8 drives the transmission ring 13 to move, and the transmission ring 13 drives the second blocking ring 14 to move the abutting sleeve 7. When the abutting sleeve 7 is separated from the outer side of the copper nose, the disassembly can be performed.
