In the illustrated exemplary embodiment, the driving member 16 is a cam provided with a driving end 162 . But the driving member 16 can also adopt other suitable structures.

现结合图1、图2和图3具体说明开关装置的联锁组件的一种示意性实施方式。A schematic implementation of the interlock assembly of the switchgear will now be described in detail with reference to FIG. 1 , FIG. 2 and FIG. 3 .

如图1、图2和图3所示,开关本体11中包括一个可连接所述插接单元20的锁定部12。第一锁定件22设有一个第一接触端222和一个第二接触端224,第一接触端222可与驱动件16接触,在驱动件16的推动下,第一锁定件22可沿插接方向运动。第一滑动件23的一端可与第二接触端224接触,第一锁定件22的第二接触面224可推动第一滑动件23沿第一锁定方向运动,使第一滑动件23的另一端连接至锁定部12,使开关本体11锁定在插接单元20上。第二锁定件24的一端可与开关本体11朝向所述插接单元的顶压端面14接触,使开关本体11可推动第二锁定件24沿插接方向运动。第二滑动件25可限制第一锁定件22沿插接方向的运动,第二锁定件24的另一端可推动第二滑动件25沿第二锁定方向运动,使第二滑动件25解除对第一锁定件22的限制。第一弹性件27可推动第一滑动件23和第二滑动件25沿与第一锁定方向和第二锁定方向相反的方向运动。在联锁组件的开关模块一种示意性实施方式中,可以通过第二滑动件25与第一锁定件22的卡接实现该限制。As shown in FIG. 1 , FIG. 2 and FIG. 3 , the switch body 11 includes a locking portion 12 that can be connected to the plug-in unit 20 . The first locking member 22 is provided with a first contact end 222 and a second contact end 224, the first contact end 222 can be in contact with the driving member 16, under the push of the driving member 16, the first locking member 22 can be inserted along the direction movement. One end of the first sliding member 23 can be in contact with the second contact end 224, and the second contact surface 224 of the first locking member 22 can push the first sliding member 23 to move along the first locking direction, so that the other end of the first sliding member 23 It is connected to the locking part 12 so that the switch body 11 is locked on the plug-in unit 20 . One end of the second locking member 24 can be in contact with the pressing end surface 14 of the switch body 11 facing the plug-in unit, so that the switch body 11 can push the second locking member 24 to move along the insertion direction. The second sliding part 25 can limit the movement of the first locking part 22 along the insertion direction, and the other end of the second locking part 24 can push the second sliding part 25 to move along the second locking direction, so that the second sliding part 25 releases the first locking part. A locking member 22 limits. The first elastic member 27 can push the first sliding member 23 and the second sliding member 25 to move in a direction opposite to the first locking direction and the second locking direction. In an exemplary embodiment of the switch module of the interlock assembly, the restriction can be realized by the engagement of the second sliding member 25 and the first locking member 22 .

图2用以说明图1所示联锁组件的开关模块10未插入插接单元20时的局部剖视示意图。开关模块10处于分闸状态时驱动件16处于如图2所示的位置,第二滑动件25的一端卡接在第一锁定件22上,在图示实施方式中,第一锁定件22与第二滑动件25的卡接部分设有一个锁定槽226,第二滑动件25的一端可卡接插入锁定槽226中,以实现对第一锁定件22运动的限制。除使用锁定槽226的形式外,还可以采用其他形式的卡接方式实现对第一锁定件运动的限制。FIG. 2 is a schematic partial cross-sectional view illustrating the switch module 10 of the interlock assembly shown in FIG. 1 when the plug-in unit 20 is not inserted. When the switch module 10 is in the opening state, the driving member 16 is in the position shown in FIG. 2 , and one end of the second sliding member 25 is engaged with the first locking member 22. The locking part of the second sliding part 25 is provided with a locking groove 226 , and one end of the second sliding part 25 can be inserted into the locking groove 226 to restrict the movement of the first locking part 22 . In addition to using the locking slot 226 , other forms of engagement can also be used to restrict the movement of the first locking member.

第二锁定件24的一端可与开关本体11上朝向插接单元20的顶压端面14接触,在驱动件16处于分闸状态的开关模块10沿图示插接方向插入插接单元20的过程中,当开关本体11的顶压端面14与第二锁定件24接触时,继续插入开关模块10便可驱动第二锁定件24沿图示的插接方向运动。第二锁定件24的另一端可与第二滑动件25的一端接触,当第二滑动件25卡接在第一锁定件22上时,第一锁定件22不能沿图示插接方向运动,但插入开关本体11可以使顶压端面14顶压第二锁定件24,第二锁定件24推动第二滑动件25沿图示的第二锁定方向运动,让第二滑动件25退出锁定槽226,释放与第一锁定件22的卡接,使第一锁定件22可以沿图示插接方向运动。One end of the second locking piece 24 can be in contact with the pressing end surface 14 of the switch body 11 facing the plug-in unit 20 , and the switch module 10 with the driver 16 in the opening state is inserted into the plug-in unit 20 along the insertion direction shown in the figure. Among them, when the pressing end surface 14 of the switch body 11 is in contact with the second locking member 24 , the second locking member 24 can be driven to move along the insertion direction shown in the figure by continuing to insert the switch module 10 . The other end of the second locking member 24 can be in contact with one end of the second sliding member 25. When the second sliding member 25 is snapped onto the first locking member 22, the first locking member 22 cannot move along the insertion direction shown in the figure. However, inserting the switch body 11 can make the pressing end surface 14 press against the second locking member 24, and the second locking member 24 pushes the second sliding member 25 to move along the second locking direction shown in the figure, so that the second sliding member 25 exits the locking groove 226 , to release the engagement with the first locking member 22, so that the first locking member 22 can move along the insertion direction as shown.

再参见图3,处于分闸状态开关模块10(参见图3中虚线所示)沿插接方向插入插接单元20后,在操作者将驱动轴30(图中未显示,参见图1)由分闸位置转动到合闸位置的同时,接触件16的转动推动第一锁定件22沿图示的插接方向运动,第一锁定件22通过第二接触端面224推动第一滑动件23沿第一锁定方向运动,第一滑动件23沿第一锁定方向的运动使得第一滑动件23的一端插入开关本体11的锁定部12,从而使得开关本体11锁定于插接单元20上,使得处于合闸状态的开关装置不能从插接单元20上拆除。Referring to Fig. 3 again, after the switch module 10 (shown by the dotted line in Fig. 3) is inserted into the plug-in unit 20 along the plug-in direction in the opening state, after the operator drives the shaft 30 (not shown in the figure, see Fig. 1 ) by When the opening position is rotated to the closing position, the rotation of the contact piece 16 pushes the first locking piece 22 to move along the insertion direction shown in the figure, and the first locking piece 22 pushes the first sliding piece 23 along the second contact end surface 224 One locking direction moves, and the movement of the first sliding member 23 along the first locking direction makes one end of the first sliding member 23 insert into the locking portion 12 of the switch body 11, so that the switch body 11 is locked on the plug-in unit 20, so that it is in the engaged position. The switching device in the gate state cannot be removed from the plug-in unit 20 .

参见图1、图2和图3,第一弹性件27可推动第一滑动件23沿与第一锁定方向相反的方向运动,使第一滑动件23复位,第一滑动件23复位时可带动第一锁定件22复位;第一弹性件27还可以推动第二滑动件25沿与第二锁定方向相反的方向运动,使第二滑动件25复位,第二滑动件25复位时可带动第二锁定件24复位。在图1所示的实施方式中,第一弹性件27是一个扭簧,它套设在插接本体21的一个定位柱29上,扭簧27的一端与第一滑动件23连接,另一端与第二滑动件25连接。扭簧还可以通过其他形式的弹性件或弹性件组合来实现,例如分别设置两个连接于第一滑动件和第二滑动件的弹簧。Referring to Fig. 1, Fig. 2 and Fig. 3, the first elastic member 27 can push the first sliding member 23 to move in the direction opposite to the first locking direction, so that the first sliding member 23 can be reset, and the first sliding member 23 can drive The first locking member 22 resets; the first elastic member 27 can also push the second sliding member 25 to move in the direction opposite to the second locking direction, so that the second sliding member 25 is reset, and the second sliding member 25 can drive the second sliding member 25 when it is reset. The locking part 24 resets. In the embodiment shown in Fig. 1, the first elastic member 27 is a torsion spring, which is sheathed on a positioning post 29 of the plug body 21, one end of the torsion spring 27 is connected with the first sliding member 23, and the other end is Connect with the second slider 25. The torsion spring can also be realized by other forms of elastic elements or a combination of elastic elements, for example, two springs connected to the first sliding element and the second sliding element are provided respectively.

在本发明的开关装置的联锁组件中,大部分联锁机构设置在插接单元中,且开关模块中只需要在开关本体上增加一个锁定件即可完成对开关装置的联锁功能,不需要改变现有的开关模块中的驱动件,对开关装置的结构影响小。另一方面,经过简单改装的不同开关模块便于安装在相同的插接单元中,增加了插接单元的通用性。In the interlock assembly of the switch device of the present invention, most of the interlock mechanisms are arranged in the plug-in unit, and in the switch module, it is only necessary to add a locking piece on the switch body to complete the interlock function of the switch device, without The driving part in the existing switch module needs to be changed, and the influence on the structure of the switch device is small. On the other hand, different switch modules that have been simply modified can be easily installed in the same plug-in unit, which increases the versatility of the plug-in unit.

如图1所示,插接单元20还设有一个第二弹性件26,它可推动第一锁定件22沿图示插接方向的反方向运动,使第一弹性件26复位。通过设置第二弹性件,可以增加第一锁定件的复位驱动力,增加第一锁定件运动的平稳性和可靠性。同时,插接单元20中还设有一个容纳槽28,第二弹性件26设置在容纳槽28中,第二弹性件26一端与插接单元20连接,另一端与第一锁定件22连接。在图1所示的实施方式中,第二弹性件26为弹簧,但也可以采用扭簧、压簧、拉簧或者板簧。As shown in FIG. 1 , the plug-in unit 20 is further provided with a second elastic member 26 , which can push the first locking member 22 to move in a direction opposite to the insertion direction shown in the figure, so as to reset the first elastic member 26 . By arranging the second elastic member, the reset driving force of the first locking member can be increased, and the stability and reliability of the movement of the first locking member can be increased. Meanwhile, the plug unit 20 is further provided with a receiving groove 28 , the second elastic member 26 is disposed in the receiving groove 28 , one end of the second elastic member 26 is connected with the plug unit 20 , and the other end is connected with the first locking member 22 . In the embodiment shown in FIG. 1 , the second elastic member 26 is a spring, but a torsion spring, compression spring, extension spring or leaf spring may also be used.

如图1所示,锁定部12为一个连接槽,第一滑动件23上远离第二锁定件24的一端可插入连接槽12中。如图1所示,第二锁定件24与第二滑动件25接触的端面为一个推压斜面242,且第二接触端224为一个驱动斜面。As shown in FIG. 1 , the locking portion 12 is a connecting groove, and the end of the first sliding member 23 away from the second locking member 24 can be inserted into the connecting groove 12 . As shown in FIG. 1 , the end surface of the second locking member 24 in contact with the second sliding member 25 is a pushing slope 242 , and the second contact end 224 is a driving slope.

如图1所示,驱动件16为一个凸轮,凸轮16设有一个驱动端162,凸轮16通过接触端162与第一锁定件22的第一接触端222接触。凸轮接触端与第一接触端为点接触,可以降低它们之间的摩擦,保证凸轮到第一锁定件传动的平稳性。As shown in FIG. 1 , the driving member 16 is a cam, and the cam 16 has a driving end 162 , and the cam 16 contacts the first contact end 222 of the first locking member 22 through the contact end 162 . The contact end of the cam is in point contact with the first contact end, which can reduce the friction between them and ensure the smooth transmission of the cam to the first locking member.

如图1所示,第二锁定件24大致成Ω形或者C形,而第一锁定件22则可穿过第二锁定件24所形成的空间中,使得第二锁定件24套设在第一锁定件22之外,这样则可以有效地节约开关模块的空间。As shown in FIG. 1, the second locking piece 24 is roughly Ω-shaped or C-shaped, and the first locking piece 22 can pass through the space formed by the second locking piece 24, so that the second locking piece 24 is sleeved on the second locking piece. Except for a locking piece 22, the space of the switch module can be effectively saved in this way.

在图1所示的实施方式中,第一锁定方向和第二锁定方向同向,但它们也可以是不同向的情形,但需要保证第一滑动件和第二滑动件相应的功能。In the embodiment shown in FIG. 1 , the first locking direction and the second locking direction are in the same direction, but they can also be in different directions, but the corresponding functions of the first sliding member and the second sliding member need to be guaranteed.

图4用于说明开关模块处于合闸状态时,联锁组件的工作过程。如图4所示,当开关模块10处于合闸状态时,驱动件16处于图中的位置。当开关模块10欲沿图示插接方向插入插接单元20时,第一锁定件22先插入开关本体11中。此时,第二滑动件25卡接于第一锁定件22的锁定槽226中,使得第一锁定件22无法沿图示插接方向运动。当第一锁定件22的第一接触端触及凸轮16的驱动端162时,开关本体11无法沿图示插接方向继续向插接单元20运动,而此时开关本体11的顶压端面14还未与第二锁定件24接触,无法通过第二锁定件24沿图示插接方向运动,第二滑动件25无法释放与第一锁定件22的卡接,从而使得处于合闸状态的开关本体11无法插接于插接单元20。Fig. 4 is used to illustrate the working process of the interlock component when the switch module is in the closing state. As shown in FIG. 4 , when the switch module 10 is in the closed state, the driving member 16 is in the position shown in the figure. When the switch module 10 is going to be inserted into the plug-in unit 20 along the plug-in direction as shown, the first locking member 22 is inserted into the switch body 11 first. At this moment, the second sliding member 25 is snapped into the locking slot 226 of the first locking member 22 , so that the first locking member 22 cannot move along the insertion direction as shown. When the first contact end of the first locking member 22 touches the driving end 162 of the cam 16, the switch body 11 cannot continue to move toward the plug-in unit 20 along the insertion direction shown in the figure, and at this time the pressing end surface 14 of the switch body 11 is still Without being in contact with the second locking piece 24, the second locking piece 24 cannot move in the insertion direction shown in the figure, and the second sliding piece 25 cannot release the engagement with the first locking piece 22, so that the switch body in the closed state 11 cannot be plugged into the plug-in unit 20.

与图2和图3所示的过程相反,当需要将开关本体11从插接单元20中拔出时,驱动轴30(图中未显示,参见图1)带动驱动件16转动到分闸位置(参见图3),从而使得驱动件16的驱动端162释放对第一锁定件22的推压,在扭簧27和弹簧26的共同作用下,第一锁定件22沿图示插接方向的反方向运动,使得驱动斜面224释放对第一滑动件23的推压,扭簧27的作用下,第一滑动件23从锁定部12中退出并最终恢复到图2所示的位置。在开关本体11从插接单元20中拔出的过程中,开关本体11朝向插接单元20的端面释放对第二锁定件24的推压,在扭簧27的作用下,第二锁定件24沿图示插接方向的反方向运动,从而释放对第二滑动件25的推压,在在扭簧27的作用下,第二滑动件25恢复到图2所示的位置,并卡接入锁定槽226中。Contrary to the process shown in Figures 2 and 3, when the switch body 11 needs to be pulled out from the plug-in unit 20, the driving shaft 30 (not shown in the figure, see Figure 1) drives the driving member 16 to rotate to the opening position (See FIG. 3 ), so that the driving end 162 of the driving member 16 releases the pushing force on the first locking member 22. Movement in the opposite direction makes the driving slope 224 release the pushing force on the first sliding member 23 , and under the action of the torsion spring 27 , the first sliding member 23 withdraws from the locking portion 12 and finally returns to the position shown in FIG. 2 . When the switch body 11 is pulled out from the plug-in unit 20, the switch body 11 releases the pushing force on the second locking member 24 toward the end face of the plug-in unit 20, and under the action of the torsion spring 27, the second locking member 24 Move in the opposite direction of the insertion direction shown in the figure, thereby releasing the push on the second sliding member 25, and under the action of the torsion spring 27, the second sliding member 25 returns to the position shown in Figure 2 and snaps in Lock slot 226.
