Abstract
The utility model discloses a switch conduction coupling device. The device comprises a static end contact seat, a static end contact finger installed and connected on the static end contact seat, a dynamic end contact seat, a dynamic end contact finger installed and connected on the dynamic end contact seat and a movement contact. The movement contact is slidingly connected in a movable contact apparatus and is slide between a closed position and an open position. The movement contact located on the closed position is conductively contacted with the static end contact finger and the dynamic end contact finger. The movement contact possesses at least one dynamic end section which is contacted and cooperated with the dynamic end contact finger when being at the closed position, one static end section which is contacted and cooperated with the static end contact finger when being at the closed position and a sliding section which is between the dynamic end section and the static end section.

Description
Technical field
The utility model relates to a kind of switches conductive coupling arrangement, relates in particular to the conductive attachment device of a kind of isolating switch or earthed switch.
Background technology
Please refer to Fig. 1, Fig. 2 and Fig. 3, the conductive attachment device of isolating switch or earthed switch, it comprises:

One cooperates the trigger device of static contact head device, and it comprises that the moved end touch base 3 and of an annular is installed in the moved end fingertip 4 of moved end touch base;
One motion contact 5, it is slidingly connected in the trigger device and between closing position and separating brake position, slides, and is positioned at the motion contact conduction quiet end fingertip of contact and the moved end fingertip of closing position.
For isolating switch or earthed switch, the stroke of motion contact 5 can be divided into two parts: first is that motion contact 5 divides the stroke that moves between (closing) position and the closing position just, and this section stroke is called contacting travel; Second portion is the stroke that motion contact 5 has moved between separating brake position and firm branch (closing) position, and this section stroke is called the noncontact stroke.Contacting travel accounts for about the 20%-40% of total kilometres, and the noncontact stroke accounts for about the 60%-80% of total kilometres (this data based construction of switch different different).
For guaranteeing that switch has good through-current capability when the closing position, require that moved end fingertip 4 has certain contact pressure with 2 pairs of motion contacts 5 of quiet end fingertip when closing position.The diameter of traditional motion contact 5 is identical, and this just caused in the noncontact stroke stage, and moved end fingertip 4 still has bigger frictional force with motion contact 5 during not conducting of electric current.The frictional force of this moment is useless to current flowing, can cause following bad problem to switch on the contrary:
1, increased the resistance of the divide-shut brake motion of switch;
2, increase the load of switch operating mechanism, reduced the life-span and the reliability of operating mechanism;
3, motion process has increased the wearing and tearing between moved end fingertip and motion contact.Usually all there is the silver coating that is used for improving the switch through-current capability on the surface of moved end fingertip and motion contact.The undue wear meeting comes off silver coating, reduces through-current capability;
4, undue wear improves the possibility that produces metal particle greatly, and metal particle comes lecture to produce discharge to switch, has a strong impact on the normal operation of switch.
