Description
Technical field
The present invention relates to a kind of contact device and electromechanical switchgear for electromechanical switchgear, contact device has solid
The switch member positioned and the moveable switch member arranged in contrast, the moveable switch member dispose in contact carrier
In the top of contact spring.
Background technology
Switchgear, such as power switch or contactor have moveable switch member, in operation connect or
Person's disconnecting circuit.The moveable switch member is maintained or is guided in moveable contact impeller, to obtain to phase
The displacement process for the final position answered, switchgear is switched on or disconnects in the final position.It is technically necessary
, in the switchgear of connection, there are one gaps relative to moveable switch member tool for contact impeller.The gap is must
It wants, compensated so as to the tolerance to all parts and the melting loss of contact material can be supplemented.Contact pushes away
Moving part can be moved freely in the inside in the gap.
In the case of electromechanical switchgear, moveable switch member is extruded in by contact spring with defined contact force
On fixed switch piece.The contact spring can be directly installed in moveable switch member, and be supported on the another of contact carrier
On side, or by spring bow spring force is transmitted in switch member, is made of steel plate under the spring bow majority situation.Spring
Bow provides advantage in short circuit by higher robustness, and smaller structure height is thus needed for whole equipment.So
And usually require additional part and assembly cost to fix contact spring.
Fig. 1 shows the contact device being known from the state of the art, with contact carrier 1, to moveable switch member 2
It is guided, wherein moveable switch member 2 is loaded by contact spring 3 on a side.In opposite side, also
It is to say, in the side of moveable switch member 2, spring bow 4 is introduced into contact carrier 1.For bearing contact spring 3, connecing
It touches and steel disk 5 is assembled by rotary motion below spring 3.
Other contact device disclosed in the prior art is shown in FIG. 2.Fig. 2 shows a kind of contact device,
With contact carrier 6, which guides moveable switch member 7, wherein moveable switch member 7 is supported on
On contact spring 8, which is inserted into from below in contact carrier 6.Equally, spring bow 9 is pushed into contact and carries from below
In body 6.Moveable switch member 7 is located at from top between two supporting legs of spring bow 9.By squeezing one end of spring bow 9,
Contact spring 8 is extruded contraction, can be pushed through from side in spring bow 9 thereby using the pin 10 in fixed switch piece
Hole in leg ends.
The contact device with spring bow being known from the state of the art has the disadvantage, in order to which fixed contact spring usually needs
Additional component is wanted, assembly cost is which thereby enhanced.
