Description
Technical field
The present invention relates to a kind of switching device, it comprises at least one first contact component, and it can move with respect at least one second contact component, reversibly to electrically contact with it, the invention still further relates to a kind of method of assembling this switching device.In addition, the present invention relates to a kind of method of operating this switching device, relate to a kind of circuit and a kind of electronic installation that comprise this switching device.
Background technology
Such as switching devices such as contactor or relays is known usually, and usually by Electromagnetically actuated, also can be under more rare situation by pneumatic actuation.
In electromagnetic relay, electromagnetic actuators can comprise the armature of electromagnet and correspondence or have the electrifiable coil of magnetic core that it can move in the electromagnetic field that the coil that electrifies (so-called solenoid) produced.
Known armature can move in electromagnetic field, or fixes with respect to movable electromagnet, and itself can be permanent magnet or electromagnet.
Said that in principle electromagnetic relay is just known since nineteen twenty-six, comprise a movable armature and arrange that as the coil and the iron core of electromagnet described a movable armature separates by spring and electromagnet.The electromagnetic attraction that electromagnet produces (greater than the power (elastic force) of spring generation) makes armature move towards electromagnet, enters active position.The contact arm of armature comprises resiliently mounted movable contact component.When armature is in active position, the corresponding fixed contact spare of movable contact component contact, described fixed contact spare conducts electricity, thereby makes circuit closed circuit via described two contact components.The flexible fastening of described movable contact component provides indivedual contact pressures.
Gap between electromagnet and the armature causes the electromagnetic field loss, yet if armature moves towards electromagnet, the gap between electromagnet and the armature reduces, thereby makes field loss reduce.Therefore, armature is towards the mobile acceleration of electromagnet, and because the mobile of armature causes movable contact component to move towards fixed contact spare, so, according to the kinetic energy of movable contact component can cause contact component take place do not wish to occur upspring.
If be supplied to the electric current of electromagnet to be cut off, then electromagnetic field begins collapse, thereby causes that electromagnetic attraction reduces.In case electromagnetic force drops to below the elastic force, armature just begins to move towards inoperative position because of elastic force.Therefore, movable contact component also moves towards open position, thereby makes open circuit.Yet, in the general special time period after failure of current, electromagnetic field is maintained at least in part, thereby undesirable delay appears in the action that makes contact component move to open position (this make open circuit), and even can not move to open position.
Contact component is not desirably opened against the action of the contact spring of movable contact, is attributable to the electric current applied force in the conductor.Described power and current strength are proportional, and current strength with power square and linear increasing.Therefore, desirably do not open based on the electric current applied force of conducting if prevent contact component, contact elastic force is and the maximum current relative restrictions factor of passing conductor.In order to make contact component contact (that is, making the contact closure), Electromagnetically actuated member must overcome contact elastic force, like this, and the maximum current that will limit " permission " contact elastic force and pass conductor.
Therefore, comprise that the relay stock size of this Electromagnetically actuated member is big, energy consumption is high, and its manufacturing cost height.In addition, also can suffer unacceptable heat dissipation problem, and the large scale of electromagnetic actuators can cause electromagnetic interference, this may desirably not influence other circuit and/or device.
Yet if the size of Electromagnetically actuated member reduces, the performance of relay (especially relevant with the ampacity of circuit and/or contact) is restricted.
In addition, mechanical shock, vibration, electrical effect etc. can cause contact accident to occur and open, and this can cause, and relay fault, current circuit damage, contact material loses or the like.
In addition, contact material loss and contact component thickness associated therewith reduce to make contact elastic force to reduce, and this causes the contact material loss to be quickened again.Therefore, break down too early, just need the size of contact component thickness be designed, so that the standard of relay does not shorten useful life in order to prevent relay.This has increased manufacturing cost, especially under the situation that contact component is made up of the material of costlinesses such as for example silver.
Therefore need have a kind of alternative switching device, can overcome or reduce in the above-mentioned shortcoming at least one at least, and the present invention just can realize this purpose.
