Detailed description of the invention
The present invention is elaborated below with reference to embodiment.Attached drawing are as follows:
Fig. 1 shows the device for being used to switch on and off switch with 4 pole boxes (Polkassetten),
Fig. 2 shows the device according to figure 1 with overhead guard (Aufsatz),
Fig. 3 shows overhead guard according to Fig.2, and
Fig. 4 shows the decomposition view of overhead guard according to Fig.3,.
Specific embodiment
Fig. 1 shows the device 1 for switching on and off disconnecting switch 2, which has 4 pole box 2a.The pole
Box 2a is fixed on the lateral upper of device 1 and respectively includes two contacts, and described two contacts can be by by switch shaft
It is separated from each other and mutually bears against (not shown).Pole box 2a can be connected to each current phase of circuit by link block 3
(Stromphasen) on.
Device 1 is located in shell 4, the prominent shell 4 in the end of drive shaft 5 and driven shaft 6.Driven shaft 6 and switch shaft pass through
Shape cooperates and is connected with each other (not shown).
Drive shaft 5 has cubic connected in star 7, and open position OFF can be gone to from on-position ON, and can be on the contrary
On-position ON is gone to from open position OFF.
Drive shaft 5 and driven shaft 6 are connected with each other by (first) mechanism (not shown).The mechanism driven shaft 5 is driven,
Wherein driven shaft 6 is gone to (first) critical point by the mechanism.In the process, it tenses automatically further after through critical point
Rotate the spring of driven shaft 6.The mechanism is used for wink manual converting mechanism herein；Driven shaft 6 therefore with hand active force and revolving speed without
Guan Di, the corresponding position of the switch always is gone to same time response curve by same active force (connect the position of the switch
Or disconnect the position of the switch).
Drive shaft 5 at least can be freely (empty at one when and then starting to automatically continue rotation after by critical point
Turn -) the interior rotation of angular zone.
Fig. 2 shows the disconnecting switch 2 with 4 pole box 2a, wherein overhead guard 8 is installed on device 1 shown in Fig. 1.The top
Cover 8 has extension 9, and there are the grooves 10 of square in the extension 9, to make to operate easier handle (not shown)
End be inserted into the groove.
Position of the switch instruction 11 includes in the tip 11a of notch 11b shape and including marking OFF and ON, as switch
Position instruction 11, the notch 11b and label OFF and ON correspondingly collective effect.OFF is marked to indicate open position, and
ON is marked to indicate on-position.The position of the switch at that time is exactly the mark position that is accordingly directed toward by notch 11b.
The separately shown overhead guard 8 in Fig. 3.It can see square toes 12, can be inserted into the cubic connected in star 7 to match.Prolong
Long section 9 extends drive shaft 5 to a certain extent.
The decomposition view of overhead guard 8 is shown in FIG. 4.The overhead guard 8 includes the second mechanism 100, passes through the square toes 12 of insertion
Apply torque to correspondingly drive shaft 7.For this purpose, cam disc 13 is torsionally disposed on extension 9, extension 9 and cam disc 13
Rotation axis be overlapped, and the outer profile 14 of cam disc 13 have vertex 14a.The outer profile 14 has such herein
Special feature, the i.e. asymmetric diametral curve of outer profile 14 are repeating after 180 ° respectively, thus occur two on excircle
Secondary vertex 14a, wherein the only visible sinciput point 14a in Fig. 4, and opposed vertex 14a is extended section 9 and is covered.In outer profile
On the position of two diametrically contrapositions on 14, transverse to drive shaft rotation axis apply torque, the torque is herein by leading
Draw produced by the helical spring 15 extended in part 16.Helical spring 15 extends parallel to each other, and is respectively relative to drive shaft 7
Or the rotation axis off-center of coaxial extension 9 dispose so that the vertex 14a of cam disc 13 each serves as critical point
The effect of (also referred to as " critical point of tumbling " or " turning point ").According to the rotation direction of cam disc 13, the bullet before critical point
Spring force generates reseting torque, and generates after critical point and continue to rotate torque.Here, spring end 17 is resisted against cam disc
It is slided on 13 edge 18 and when cam disc 13 is rotated along edge 18.
It means that described two torque energies directly invert its direction of rotation after the 14a of vertex respectively.
Realize that extension 9 is determined on on-position or open position in corresponding idle angular region in this way
Position avoids the idle running of extension 9 and thus avoids the idle running of drive shaft 7.Therefore, position of the switch instruction 11 is correspondingly shown just
Whether true position, i.e., correct display switch are switched on or disconnect.
Second critical point of the cam disc 13 of overhead guard 8 is worthily located at the rear of the first critical point of the first mechanism, and
