***式断路器Plug-in circuit breaker 技术领域Technical field

背景技术Background technique

通讯行业中，标准机柜以1U为一个工作单元，其高度约为44.45mm。随着通讯技术的高速发展，机柜内部的元器件需不断地小型化以满足1U单元的安装尺寸要求，以提高机柜内元器件的密度来节省通讯设备的整体体积。In the communications industry, a standard cabinet uses 1U as a working unit, and its height is about 44.45mm. With the rapid development of communication technology, the internal components of the cabinet need to be continuously miniaturized to meet the installation size requirements of the 1U unit, so as to increase the density of the components in the cabinet to save the overall volume of communication equipment.

现有的普通的小型断路器其高度通常在80mm至90mm之间，再加上进、出线端导线接线的空间，需要占用3U的高度，制约了通讯机柜小型化的发展；另外，普通小型断路器的出线端位置位于机柜的内部，不利于用户接线。再者，普通的小型断路器，如果增加辅助信号功能，往往需要在断路器的侧面增加辅助触头附件或其他类似功能附件来实现，增加了使用成本，占用了更多安装空间，不利于通讯机柜的小型化发展。The height of the existing ordinary miniature circuit breaker is usually between 80mm and 90mm. In addition to the space for the wire connection at the inlet and outlet ends, it needs to occupy a height of 3U, which restricts the development of the miniaturization of the communication cabinet; in addition, the ordinary miniature circuit breaker The outlet end of the cable is located inside the cabinet, which is not conducive to user wiring. Furthermore, for ordinary miniature circuit breakers, if the auxiliary signal function is added, auxiliary contact accessories or other similar functional accessories are often added to the side of the circuit breaker to achieve this, which increases the use cost, takes up more installation space, and is not conducive to communication. The miniaturization of the cabinet is developed.

结合图16-18所示，以下将对所述的锁定机构的工作原理进行说明：With reference to Figures 16-18, the working principle of the locking mechanism will be described below:

如图16所示，所述***式断路器处于分闸状态，操作按钮1d通过指示件7的指示件水平臂74、第二锁定件8的第二锁定件受动部81配合，驱动第二锁定件8顺时针转动，第二锁定件8的第二凸起82移入断路器壳体内，此状态(分闸状态)下，***式断路器能被装入断路器装配位(例如机柜)；如图18所示，所述***式断路器处于分闸状态时，继续拉拔操作按钮1d，操作按钮1d通过指示件7的指示件水平臂74、第二锁定件8的第二锁定件受动部81的配合，驱动第二锁定件8继续顺时针转动，第二锁定件8的第二锁定件主体84下端、第二凸起82分别驱动第二受动凸起94、第一受动凸起91，使第一锁定件9的第一凸起90移入断路器壳体内，从而解除***式断路器与断路器装配位的壳体的限位配合，使***式断路器能够从断路器装配位拆卸下来；如图17所示，所述***式断路器处于合闸状态时，所述操作按钮1d带动指示件水平臂74下移，指示件水平臂74通过第二锁定件受动凸起83驱动第二锁定件8逆时针转动，使第二凸起82突出在断路器壳体外部，此状态(合闸状态)下，第二凸起82突出在断路器壳体外，由于指示件水平臂74对于第二锁定件受动凸起83的限位，第二凸起82无法被挤压入断路器壳体，因此***式断路器处于合闸状态时，无法装配至断路器装配位；所述***式断路器在分闸状态和合闸状态之间切换时，由于指示件轨道轴75与指示件轨道槽的配合，指示件7也会在操作按钮1d的指示件插槽内往复移动，从而在***式断路器合闸时，合闸指示面70与指示孔12d相对(优选的，此时指示件轨道轴75位于第二竖直槽和倾斜槽的连接处)，***式断路器在分闸时，分闸指示面71与指示孔12d相对(优选的，此时指示件轨道轴75位于第一竖直槽和倾斜槽的连接处，继续拉拔操作按钮1d，则指示件轨道轴75沿第一竖直槽滑动，至第二锁定件8驱动第一锁定件9与断路器装配位的壳体解除限位配合)。As shown in Figure 16, the plug-in circuit breaker is in the open state, and the operating button 1d is matched by the indicator horizontal arm 74 of the indicator 7 and the second locking member 81 of the second locking member 8 to drive the second The locking member 8 rotates clockwise, and the second protrusion 82 of the second locking member 8 moves into the circuit breaker housing. In this state (opening state), the plug-in circuit breaker can be installed in the circuit breaker assembly position (such as a cabinet); As shown in Figure 18, when the plug-in circuit breaker is in the open state, continue to pull the operating button 1d. The operating button 1d is received by the indicator horizontal arm 74 of the indicator 7 and the second locking member of the second locking member 8. The cooperation of the moving part 81 drives the second locking member 8 to continue to rotate clockwise. The lower end of the second locking member body 84 and the second protrusion 82 of the second locking member 8 drive the second moving protrusion 94 and the first moving part respectively. The protrusion 91 moves the first protrusion 90 of the first locking member 9 into the circuit breaker housing, thereby releasing the limit fit between the plug-in circuit breaker and the housing of the circuit breaker assembly position, so that the plug-in circuit breaker can be removed from the circuit breaker The assembly position is disassembled; as shown in Figure 17, when the plug-in circuit breaker is in the closed state, the operating button 1d drives the indicator horizontal arm 74 to move down, and the indicator horizontal arm 74 is protruded by the second locking member. The driver 83 drives the second locking member 8 to rotate counterclockwise so that the second protrusion 82 protrudes outside the circuit breaker housing. In this state (closed state), the second protrusion 82 protrudes outside the circuit breaker housing, due to the indicator The horizontal arm 74 limits the position of the movable protrusion 83 of the second locking member. The second protrusion 82 cannot be squeezed into the circuit breaker housing, so when the plug-in circuit breaker is in the closed state, it cannot be assembled to the circuit breaker assembly position When the plug-in circuit breaker is switched between the open state and the closed state, due to the cooperation of the indicator track shaft 75 and the indicator track groove, the indicator 7 will also move back and forth in the indicator slot of the operation button 1d , So that when the plug-in circuit breaker is closed, the closing indicating surface 70 is opposite to the indicating hole 12d (preferably, the indicator track shaft 75 is located at the junction of the second vertical slot and the inclined slot at this time), the plug-in circuit breaker When opening, the opening indicating surface 71 is opposite to the indicating hole 12d (preferably, the indicating member track shaft 75 is located at the junction of the first vertical groove and the inclined groove at this time, and the operation button 1d is continued to be pulled, then the indicating member track The shaft 75 slides along the first vertical slot until the second locking member 8 drives the first locking member 9 to release the limit fit with the casing of the circuit breaker assembly position).

The nut 2f moves axially along the terminal screw 2e. At the same time, the nut 2f drives the end of the crimping plate 2g and the terminal plate 2j to lift up to press the wire It is tightly located between the crimping board 2g and the wiring board 2j. Further, the nut member 2f is in position-limiting cooperation with the terminal assembly cavity for accommodating the terminal block, preventing the nut member 2f from rotating, and can only move along the axial direction of the terminal screw 2e.

需要指出的是，本实施方式的接线端子，其螺母件2f也可以不与容纳接线端子的端子装配腔限位配合，而是仅依靠螺母件2f与压线板2g之间接触产生的摩擦力，以限制螺母件2f跟随接线螺钉2e转动；另外，由于螺母件2f为一异形件，其重心位于螺母件2f的一端，不与接线螺钉2e的轴线重合，因此在产生一个偏心力，限制螺母件2f跟随接线螺钉2e转动。此外，本实施方式的接线端子，其螺母件2f和接线螺钉2e也可以是固定相连(取代螺纹连接)，而且接线螺钉2e与端子装配腔的壳体螺纹配合，旋拧接线螺钉2e时，接线螺钉2e相对于端子装配腔移动，同时带动螺母件2e移动，同样可以驱动压线板2g动作。It should be pointed out that, in the terminal of this embodiment, the nut member 2f may not be matched with the terminal assembly cavity that contains the terminal, but only rely on the friction force generated by the contact between the nut member 2f and the crimping plate 2g. , To restrict the nut 2f from rotating with the terminal screw 2e; in addition, because the nut 2f is a special-shaped piece, its center of gravity is located at one end of the nut 2f and does not coincide with the axis of the terminal screw 2e, so an eccentric force is generated to limit the nut The piece 2f rotates following the terminal screw 2e. In addition, in the terminal of this embodiment, the nut 2f and the terminal screw 2e can also be fixedly connected (instead of threaded connection), and the terminal screw 2e is threaded with the housing of the terminal assembly cavity. When the terminal screw 2e is screwed, the wiring The screw 2e moves relative to the terminal assembly cavity while driving the nut 2e to move, which can also drive the crimping plate 2g to move.
