Two fixed contacts are snugly forced together and/or lift from two fixed contacts.
Background technology
Such switch is disclosed in DE2644411C2.
With housing, housing has the lower component of cup-shaped, inserts the engaging means of temperature control to lower component known switch.Under
Part is closed by upper-part, and the edge of pull-up of the upper-part by lower component is maintained in lower component.Lower component can be by gold
Category or insulant are made, and upper-part here is all made up of insulant under any circumstance.
There are in upper-part two rivets, head is used as the fixed contact for engaging means in which.Engaging means holds
The electric current transmission sections in the form of touching bridge is carried, silver coating is set on the upper surface of which, which has two docking being connected with each other
Contact, butt contact are placed in and are electrically connected to each other in the reclining of two fixed contacts and with which according to the difference of temperature.
The head of two outsides of two rivets is used as outside terminal.
Temperature detect switch (TDS) is with the circular bimetallic rotating sheet of top view and in the circular spring of top view
Rotating sheet, which is passed through by the peg for carrying tactile bridge at center.Spring rotating sheet is circumferentially guided in the housing, and bimetallic upset
Piece is supported on the supporting surface formed by the edge of the shoulder or spring rotating sheet of lower component according to the difference of temperature and additionally
Realize tactile bridge reclining on two fixed contacts or realize tactile bridge and lift from fixed contact and open, so as to interrupt outside
Electrical connection between terminal.
This temperature detect switch (TDS) is applied to prevent electrical equipment overheated in known manner.For this purpose, switch and electrical equipment to be protected
Connect and be mechanically arranged on as follows on electrical equipment, i.e., which is in thermally coupled with electrical equipment.
Below the response temperature of bimetallic rotating sheet, tactile bridge is abutted on two fixed contacts, so that circuit
Close and electrical equipment to be protected is by switching power supply.If temperature is increased to exceed permissible value, bimetallic rotating sheet is by tactile bridge
Lift from fixed contact, thereby turn off switch and interrupt the power supply of electrical equipment to be protected.
The electrical equipment of power-off now can be cooled down once again.Here, also cool down simultaneously with the switch of electrical equipment thermal coupling, which is immediately certainly
It is dynamic to close again.
By carrying out size design to touching bridge, known switch (can be opened in this temperature control compared to other temperature detect switch (TDS)s
The Central Shanxi Plain, the operating current of electrical equipment to be protected directly pass through bimetallic rotating sheet or the flowing of corresponding spring rotating sheet) draw
Lead and be higher by many operating currents, so which can be used larger electrical equipment of the protection with higher power consumption.
As described above, the automatic reclosing after the electrical equipment cooling protected by which of known switch.Such switch performance
It is meaningful when such as hair dryer is protected, and turn on automatically again is not allowed after it has been broken in electrical equipment to be protected
It is undesirable during avoiding and damage.This is such as applied to the motor for being used as drive train.
Therefore, DE19827113 suggestions, arrange a kind of so-called self-sustaining resistance, and which is electrically in parallel with outside terminal.Self-insurance
Hold resistance to connect with electrical equipment to be protected when switching off, now, due to the resistance value of self-sustaining resistance, only flow through electrical equipment
Cross harmless residual current.The residual current only be enough to heat self-sustaining resistance, and until its radiating, the heat is by double gold
Category rotating sheet is maintained at more than its switch temperature.
The disclosed switches of DE19827113 can also be implemented with the switching function of current control, arrange for this another
Individual resistance, which is enduringly connected with outside terminal.Thus the operating current of electrical equipment to be protected flows continuously through the thermal resistance, the heat
Resistance can be designed as follows, i.e., which is responsible for for bimetallic rotating sheet being heated to above its response when more than certain operating current
It is more than the temperature of temperature so that switch when operating current is improved before electrical equipment to be protected is heated with not allowing
Jing disconnects.
Although known switch has technically been proven, its service life is limited due to the high current connected
System.The number of times of switch process is higher, and the contact resistance between fixed contact and electric current transmission sections is bigger.The contact electricity of rising
Resistance also limit possible service life.
The content of the invention
From prior art, it is an object of the present invention to expend that with less design aforementioned switches are improved, so as to extend
Its service life.
According to the present invention, the purpose is implemented as described below for aforementioned switches, i.e., on the edge of rotating sheet and/or for side
At least one uneven body (Unebenheit) is set on the supporting surface of edge so that rotating sheet is perpendicular around which in each switch process
Axle rotates.
The purpose of the present invention is perfect by this way to be realized.
" uneven body " is arranged on the edge sheet of rotating sheet in scope of the invention and alternatively or in addition
It is additionally arranged on the supporting surface for edge.The supporting surface can be shoulder, in disconnection and/or closure switch on the shoulder
Support rotating sheet.
" uneven body " is interpreted as in the scope of the invention edge end face and/or correlation supporting surface with so far
It is being made every effort in the prior art, with the difference of the planarization of smooth ring surface form, which results in edge no longer in circumference
On on shoulder equably in lower component is abutted in or on ring surface, this is because support contact can be described as what is bent,
So that the support of edge formation such as crooked, the rising or decline on the edge of rotating sheet or for rotating sheet
Face.
Uneven body can be rotating sheet edge in or for raised or sunken on the supporting surface at edge.Uneven body may be used also
To extend on almost 360 ° of neighboring area more than 180 °.So, it is related to a kind of edge of bolt shape or for edge
The supporting surface of bolt shape, so as to set the rotation effect for rotating sheet, this effect always extends to equidirectional.
If arranging multiple uneven bodies, which can be upwardly extended 45 ° to 90 ° of week respectively.
Present inventors have realized that, such uneven cognition causes rotating sheet and thus also results in electric current transmission sections
Rotate in each switch process, and rotate less, be i.e. only several years.It is this slightly be rotated in disconnection and/or closure switch
When can cause, when new switch is closed after once disconnection process again not always same position make electric current transmit sections
Contact with butt contact.
In other words, the contact surface for transmitting sections offer in electric current is better utilized, so that being transmitted by electric current
The contact resistance component that sections is caused is assigned to multiple different contact positions, and the life-span is correspondingly made available prolongation, Zhi Daojie
Resistance of getting an electric shock generally has reached the value not allowed.
The cognition of inventor of the invention, the effect of the rotating sheet of this rotation have first resulted in electric current transmission sections
On the component of contact resistance slowly rise.This will not be with the onesize value suitable for fixed contact on contact resistance.
The but rotation of this electric current transmission sections also results in contact resistance component on fixed contact with switch process
More slowly rise than prior art.
It is all these to have resulted in the service life that improve known switch in design in a straightforward manner, be this only
The edge or its supporting surface of rotating sheet need to correspondingly be designed.In addition the known temperature detect switch (TDS) for high current can be retained
The design variant put into practice.
With it is be expected by contrast, this rotating sheet being anisotropically fitted on the shoulder arranged for this is not result in connect
Touch pressure reduces or or even negative effect switch performance itself.
If at least one uneven body is arranged on the supporting surface for the edge of rotating sheet, rotating sheet itself need not be carried out
Change in design, realizes the rotation effect according to the present invention therefore, it is possible to using common rotating sheet.Here it is advantageous when,
The thermal characteristicss and mechanical property of rotating sheet need not be redesigned.
If extra uneven body is arranged on rotating sheet, which can be coordinated as follows with the uneven body on supporting surface, that is, exist
Rotating sheet is caused slightly to rotate in switching every time.These uneven bodies can coordinate as teeth portion, and such as which is such as in spring ball
Application in pen like that, there, all causes the rotation of switch frame for movement in pressing motion each time, so as to first
So which is retracted again in causing refill for ball-point pen to stretch out and press at second during secondary pressing.
Rotating sheet can also be bimetallic rotating sheet, and which causes the disconnection campaign of clossing pressure and temperature control.But, closure pressure
Power individually or extraly can also be applied by spring rotating sheet, and arrange bimetallic rotating sheet or only cause disconnection motion
Or also cause contact pressure under its low temperature state.
Correspondingly, or only the edge at the edge or two kinds of rotating sheets of bimetallic rotating sheet or spring rotating sheet according to
The present invention is furnished with least one uneven body.Uneven body extraly can be also set in above-mentioned meaning on the support surface.
But for the rotation effect according to the present invention, only turn on the edge of bimetallic rotating sheet or for bimetallic
It is just enough that the edge of rotor arranges at least one uneven body.When switch is disconnected, bimetallic rotating sheet is arrived with its edge
Up to switch in the reclining of supporting surface in, this result in rotation of the bimetallic rotating sheet relative to housing due to uneven body.This
Outward, if bimetallic rotating sheet also causes contact pressure in the closed state of the switch or whether this pressure only passes through spring
It is unessential that rotating sheet is realized.
It is therefore preferable that rotating sheet is bimetallic rotating sheet, which is mechanically connected with electric current transmission sections and by electric current

On lift, in addition further preferably by spring rotating sheet be arranged on electric current transmission sections and bimetallic rotating sheet between.
On the one hand only arrange and both produced bimetallic rotating sheet that contact pressure disconnects with also being responsible for temperature control just enough, the opposing party
Face can cause by being additional to bimetallic rotating sheet or individually the spring rotating sheet of contact pressure that bimetallic rotating sheet is existed
Mechanically discharge under its low temperature state, this is beneficial to the larger long-time stability of its switch performance.
It is furthermore preferred that electric current transmission sections be circular contact disc, its its towards fixed contact table
It is furnished with the contact surface for closing in the circumferential on face.
Contact disc preferably by the rivet of axle journal shape in central authorities and bimetallic rotating sheet and if necessary with spring rotating sheet
