As previously mentioned, the present invention relates to be used for the equipment of interruptive current, for example the switch cutter.
This equipment comprises in known manner: shell 1, the one or more fixed contacts 21 that are fixed to shell 1, mobile contactor 22, carriage 3, spring 41, actuating device 5 and holding device 6.
Secondly, this equipment generally also is included between shell 1 and the carriage 3 second spring 42 with compress mode prestress, and this second spring 42 for example is made up of helical spring and the offset bracket 3 for good and all towards the inertia position of carriage 3.
This mobile contactor 22 is slidably mounted in the carriage 3 along axial direction Z.
Support in the inertia position of this carriage 3 (Fig. 5 and 6) and at holding position (Fig. 7 to 10) in the final interlocking position (Figure 13 and 14) of this mobile contactor 22 at carriage 3 of the block piece 30 prop up carriage 3 and still be applied on each fixed contact 21.
The preferred spring 41 that also is made up of helical spring is encapsulated in the carriage 3 and with compress mode prestress.
Therefore, the end 411 of spring 41, i.e. the lower end of this spring on the accompanying drawing, with point to fixed contact 21 promptly the elastic force of the bottom on Fig. 2 to 14 be applied on the mobile contactor 22 along axial direction Z.This elastic force therefore antagonism is applied by spring 42 but has the power of high value.
The function that comprises the actuating device 5 of eccentric 51 and combined connecting component 52 is the compression that increases spring 41, it can be resisted by second spring 42 be applied to the antagonism restoring force on the carriage 3 and carriage 3 is moved towards its final interlocking position from its inertia position.
For this purpose, the eccentric 51 that is installed in the shell 1 around its main shaft 510 in rotary manner has handle 511, and handle 511 makes and becomes possibility from the external control eccentric 51 of shell 1.
In addition; Combined connecting component 52 has end 521 and end 522; End 521 is connected to eccentric 51 with film mode (cinematically), and end 522 acts on the end 412 of spring 41, promptly acts on the higher end of this spring 41 in the illustrated layout among Fig. 2 to 14.
Therefore, the action that acts on handle 511 that applies in the outside of shell 1 makes and causes that eccentric 51 becomes possibility around its main shaft 510 rotations and combined connecting component 52 slips.
More accurately; Eccentric 51 and combined connecting component 52 can be therefore on Fig. 5 and 6 visible resting position visible final interlocking position on Figure 13 and 14 move simultaneously, especially through bonding station visible on Fig. 7 and 8 and through visible off-position on Figure 11 and 12.
Between this moving period; Actuating device 5 is by means of the end 522 of combined connecting component 52 and masterpiece is used on the end 412 of spring 41 along axial direction Z; This power is pointed to fixed contact 21; Promptly on Fig. 2 to 14 towards down, and have the effect that increases the compression of spring 41 from the bonding station of these actuating devices, as illustrated in Fig. 7 and 8.
The holding device 6 that comprises the retaining member 61 that is connected to shell 1 is designed to for any position that actuating device 5 changes carriage 3 remained on its holding position (Fig. 7 to 10) between its bonding station (Fig. 7 and 8) and its off-position (Figure 11 and 12), and when actuating device 5 passes through its off-position (Figure 11 and 12), discharges carriage 3.
When actuating device 5 during through its off-position, carriage 3 through by these actuating devices 5 to heavens the spring 41 of prestress the part expansion and suddenly move towards its final interlocking position.
Under this background, contribution of the present invention mainly relates to simplifies holding device 6.
According to the present invention, the retaining member that is connected to shell 1 is made up of the shoulder 61 of shell, and these holding devices 6 also comprise ratchet 62, and ratchet 62 is around preferably pivotally being installed on the carriage 3 transverse to the rotation X of axial direction Z.
Ratchet 62 comprises (Fig. 3) cam member 621 and stayed surface 623, and cam member 621 extends with respect to axial direction Z obliquely, and stayed surface 623 matches with shoulder 61, so that carriage 3 is remained on its holding position.
Between the resting position (Fig. 5 and 6) and bonding station (Fig. 7 and 8) of actuating device 5; Spring 42 is pushed progressively; And the stayed surface 623 of ratchet 62 becomes more near shoulder 61, and up to the bonding station at these actuating devices 5, stayed surface 623 touches shoulder 61.
Then, stayed surface 623 makes to continue to move towards its off-position shown in Fig. 9 and 10 at the actuating device 5 that surpasses its bonding station in the support on the shoulder 61 and carriage 3 is remained on its holding position when also compressing spring 41 progressively and become possibility.
In addition, the end 522 of combined connecting component 52 cooperates with cam member 621, so as at actuating device 5 when its bonding station changes to its off-position, cause that ratchet 62 alleviates the corresponding rotation (Figure 10) of direction around its rotation X along D.
Yardstick is formulated in this rotation, makes that at actuating device 5 stayed surface 623 of ratchet 62 moves away from the shoulder 61 of shell 1 during through its off-position (Figure 12), thereby makes that spring 41 can be towards its final interlocking position movable support bracket 3 suddenly.
In fact; Like Fig. 8, shown in 10 and 12; Cam member 621 can be formed as and make 522 of the ends of combined connecting component 52 cause ratchet 62 illustrated centre position rotation from Figure 10, i.e. an end near the path of actuating device 5 from its bonding station towards its off-position.
Preferably, like what Fig. 1 illustrated especially, extend transverse to axial direction Z and transverse to the middle body (median portion) of the combined connecting component that is connected these ends simultaneously with 522 the end 521 of combined connecting component 52.
The end 522 of therefore, realizing combined connecting component 52 is directly by on the end that is pressed in spring 41 412 and not rely on adapter be possible.
Advantageously, shoulder 61 can form with the diapire 10 that shell 1 is provided.
In this case, preferred, the leading flank 32 of carriage 3 is also passed in the end 522 of combined connecting component 52, promptly this carriage with trailing flank 31 abreast and in the side that is provided with apart from trailing flank 31 1 distance.
The trailing flank 31 of carriage 3 also can be provided advisably, make it have the slit 310 that is parallel to axial direction Z, and this slit 310 crossed by the end 522 of combined connecting component 52, to guarantee guiding this end 522.
For the stability that makes ratchet 62 reaches volume best and minimizing holding device 6, between the rotation X and stayed surface 623 that the cam member 621 of ratchet is advantageously provided at this ratchet 62.
Therefore the end 522 of combined connecting component 52 can match with this second cam member 622; So that when its final interlocking position changes to its inertia position, cause the corresponding rotation (Fig. 3) along the direction of protector A around its rotation X of ratchet 62 at carriage 3; This rotation makes the stayed surface 623 of ratchet 62 be repositioned at the position that engages potentially with the shoulder 61 of shell 1, and does not rely on additional springs.
Also illustrate like Fig. 3; Ratchet 62 can have hole 620; Hole 620 is limited and is arranged on closed edge between the stayed surface 623 of rotation X and ratchet 62, makes that each cam member in the cam member 621 and 622 of this ratchet can be defined by the part corresponding to the edge in this hole 620.
