Description
Technical field
The present invention relates to a kind of self-holding temperature detect switch (TDS), has housing, this housing comprises the second housing parts of the first housing parts and sealing the first housing parts, wherein, the engaging means of temperature control is set in housing, it is set up conduction and is connected being arranged on outside terminal between the first housing parts and the second housing parts according to its temperature, wherein, externally at housing resistance component is set, it is electrically connected with in two outside terminals first with its first port and is electrically connected with second in its second port and two outside terminals.
Background technology
This type of temperature detect switch (TDS) is open in DE4142716A1.
Known temperature detect switch (TDS) comprises the lower housing portion of being made by electric conducting material, and the temperature control engaging means with bimetallic upset disk and spring upset disk is placed in this lower housing portion.
Engaging means is at central support movable contact spare, and it cooperates with fixed contact therefor, and fixed contact therefor is arranged on the housing top of electric insulation, and lower housing portion is by this housing closed upper part.
Spring upset disk presses to fixed contact therefor with movable contact spare in inner support with its edge on lower housing portion and simultaneously.Between the fixed contact therefor on lower housing portion and housing top, exist by this way conduction to be connected.
If the temperature of engaging means is brought up to the response temperature that has surpassed bimetallic upset disk now, then the bimetallic upset disk power that overcomes spring upset disk is lifted movable contact spare and disconnect thus temperature detect switch (TDS) from fixed contact therefor.
If the temperature of engaging means is cooled to be lower than its resilience temperature, then bimetallic upset disk is turned in its low temperature position again, thereby so that on the position that spring upset disk can be brought movable contact spare into again with fixed contact therefor contacts, like this, switch is again closed.
Known switch is applied to the overtemperature protection of electrical equipment as a lot of other these type of temperature detect switch (TDS)s.For this purpose, known temperature detect switch (TDS) electricity is connected in series in the current supply circuit of shielded electrical equipment, thereby so that the supply current of electrical equipment flows through temperature detect switch (TDS).
In addition, temperature detect switch (TDS) and shielded electrical equipment hot link, thus (where necessary with certain delay) follows the variations in temperature of shielded electrical equipment.
If electrical equipment is heated to now by on the default allowable temperature of the response temperature of bimetallic upset disk, then cause temperature detect switch (TDS) to disconnect in the above described manner, thus the supply current of middle circuit breaker, thus can again be cooled.
The cooling of electrical equipment also causes the cooling of temperature detect switch (TDS), thereby makes it again closed and again to electric power supply.
This type of temperature detect switch (TDS) is such as being common in hair dryer, and it is cut off when overheated and can reuses immediately after cooling.
But in a lot of other electrical equipment, do not wish this automatic switchover, because this can cause unpredictalbe damage of shielded electrical equipment.Do not wish that the example of the automatic electrical equipment of connecting is such as the motor in the washing liquid pump that is arranged on washing machine again.
Desirable for these electrical equipment is that it is not again automatically to connect after owing to overheated being cut off, but just may again connect these electrical equipment in the situation that disconnect first before power supply.
This is necessary in the washing liquid pump of mentioning before, because the washing liquid pump is because napping etc. may be mechanically stuck, thereby so that motor heated after automatically connecting again again each, this finally may cause the damage of motor or even cause cable fire.
On the contrary, if electrical equipment must initiatively be cut off, then the user can be alerted and have a mistake, and it can be such as cleaning the washing liquid pump.
Aforementioned temperature detect switch (TDS) is for this function repacking, and therefore, it is furnished with so-called resistance component, and this resistance component is in parallel with two outside terminals of switch.As long as temperature detect switch (TDS) is closed, then engaging means also is known as the resistance component of resistance of controlling oneself with regard to bridge joint is this, thereby its operating current to shielded electrical equipment is not exerted an influence.
If but the temperature detect switch (TDS) open circuit, then residual current flows through now the no longer self-holding resistance of short circuit.
The resistance value of self-holding resistance is selected as at this; only there is minimum residual current to flow in the shielded electrical equipment; this can not cause the further damage of electrical equipment on the one hand; temperature detect switch (TDS) can heat self-holding resistance on the other hand, so that can be held in place on the temperature that recloses on the temperature (R ü ckschalttemperatur).
In other words, in resistance component, just produce abundant ohm heat in the situation that disconnect temperature detect switch (TDS), so that bimetallic upset disk can not be cooled on the following temperature of its resilience temperature.
Temperature detect switch (TDS) remains open by this way, until circuit is interrupted.This type of temperature detect switch (TDS) is also called self-holding switch.
For the circuit of user's active break, no longer include residual current by resistance component, thereby so that temperature detect switch (TDS) can be cooled on the whole and finally again closed.
For known temperature detect switch (TDS), resistance component is base, and it is furnished with resistance paste (Widerstandspaste), adheres to the lead-in wire port at resistance paste.
How described two embodiment and resistance component in DE4142716A1 can mechanically externally remain on the housing of temperature detect switch (TDS).
In the first embodiment, relay ring is set
, it is inserted on the lower housing portion and realizes thus and the electrically contacting of lower housing portion from below.Relay ring has the plate that band keeps liner plate at its downside, and in keeping liner plate, resistance component is maintained on the holding plate.
On an one port, resistance component is electrically connected with lower housing portion by maintenance liner plate and relay ring, and another port is connected with fixed contact therefor by twisted wire in a not shown manner.
In a second embodiment, resistance component is arranged in the above in the zone of fixed contact therefor and by connecting bow (Anschlussb ü gel) and is fixed on the housing.
The resistance component details that electrically contacts is not in this embodiment described in the document.
But the document mentioned member connection, be that the contact of base should realize by clamping connection/riveting and being combined in the SMD technology of being welded to connect.
Shortcoming in this design is, resistance component on housing structure and be arranged on and technically be complicated and owing to be welded to connect making and expend.
If resistance component is arranged on below by means of relay ring on the base plate of known switch, it has hindered the hot link with shielded electrical equipment, because this hot link only realizes by the holding plate in the middle of being positioned at.
On the contrary, if resistance component is arranged on the cover piece, the hot link of resistance component and temperature detect switch (TDS) is inadequate, because the heat that is used for controlling oneself that produces in resistance component must pass the inside that the lid of insulation arrives temperature detect switch (TDS).
DD119497A1 discloses a kind of unlimited self-holding temperature detect switch (TDS), wherein, at the strutting piece that insulate the first lug plate is set, it is connected with bimetallic spring, and second lug plate, it is connected with fixed contact therefor, and fixed contact therefor cooperates with the free end of bimetallic spring.Have resistive element at bimetallic spring, it keeps by conductive clip, and conductive clip abuts on the resistive element and with its another alar part with an one alar part and abuts on the second lug plate.
