Description
Technical field
The present invention relates to electrical overvoltage protective modules and its method that a kind of circuit board is mountable to circuit board.
Background technology
Today, overvoltage protective module are used for multiple technical fields.Wherein, overvoltage protective module is generally also provided with protection member
Part, or to make over-voltage protection element short circuit (and thus example in the case where the over-voltage protection element of script overloads
Such as backup fuse is caused to trigger) or the isolation over-voltage protection element.Wherein, overload is identified as example causing
The thermal parameter of hot melt connection separation, this hot melt connection lead to isolation or short circuit again.Here mechanism is normally based on, and is borrowed
A kind of (switch) element of bias can first be fixed by the adhesive (adhesive/solder flux) of heating power softening/decomposition by helping.If temperature
Rise and exceeds a specific temperature, then, described adhesive just decomposes and/or softens and release stored energy and uses
In switching process.
Thus a kind of demand growing day by day is developed, i.e. these overvoltage protective modules are also wanted to be inserted on circuit board.
But occurs a huge problem herein, because installing these overvoltage protective modules warp by welding technique
Often already result in the erroneous trigger of the protection element.
In the past, what thus this problem e.g. solved, i.e.,：The safety element is only in the overvoltage protective module
It is just biased after welding on circuit boards.
Invention content
The purpose of the present invention is to provide a kind of electrical overvoltage protections for being mountable to circuit board simple, cost is not high
Module and its a kind of method for installation are in the prior art one or more insufficient to solve.
The solution of above-mentioned purpose is obtained according to the present invention by the feature described in independent claims.The present invention's has
Profit design is illustrated by dependent claims.
Description of the drawings
By preferred embodiment, the present invention is further explained with reference to the accompanying drawings.
Wherein：
Fig. 1 schematically shows a kind of component of overvoltage protective module according to the present invention.
Mark explanation：
Overvoltage protective module 1
Overvoltage protection element
Switch element SE
Hot trigger point TAS
Installation tool ME
Accumulator F
Terminal A (A1, A2)
Specific implementation mode
Fig. 1 schematically shows a kind of component of overvoltage protective module according to the present invention.
The electrical overvoltage protective module 1 for being mountable to circuit board has suitable over-voltage protection elementWith open
Close element SE.The switch element SE is illustratively shown as the over-voltage protection elementTerminal A2Remove item
Band, wherein this is merely exemplary to show, and can also be applied to short circuit connection in the same way according to basic imagination
Device.Under the premise of not limiting above-mentioned setting generality, the over-voltage protection elementCan still have it is one or more other
Terminal A1。
In addition, one hot trigger point TAS of setting and the over-voltage protection elementIn thermo-contact.
It for example thus realizes in Fig. 1, i.e.,：The hot trigger point TAS is disposed in the overvoltage protection as pad
ElementOn.
In the over-voltage protection elementThe hot trigger point TAS there is be impermissible for heating in the case of, institute
Adhesive (adhesive/solder flux) is stated with regard to softening/directed force F of accumulated energy, such as biasing spring is decomposed and releases,
Thus the switch element SE actions are triggered.
In the example of fig. 1, the switch element SE constitutes accumulator F, and the hot trigger point TAS constitutes heat
Fuse wire, wherein described to remove strips S E while also forming the over-voltage protection elementTerminal A2(such as
In SMD technologies).
The switch element SE can make the overvoltage protective module according to the implementation type of the safety element respectivelyOpen circuit or short circuit.
Now in order to avoid being triggered in advance when being installed on circuit board, a kind of installation tool ME is set, is prevented due to electricity
Road plate installation for example passes through the temperature action triggering hot trigger point TAS in welding process, wherein the installation tool ME
It can be removed after installation is complete.
Wherein, the installation tool ME can have different shapes.Therefore, the installation tool ME can be for example implemented as
Adhesive tape is embodied as clamping screw etc..It can intervene or pass through by active force respectively according to the type of the installation tool
Other tools realize the removal of the installation tool ME.
The installation tool can be also dissolved in the cleaning step for example in circuit board installation by way of chemistry.
Therefore, do not have to hell to pay now, it will be able to a kind of installable electrical overvoltage protective module 1 of circuit board is formed,
The cost of installation can be highly beneficial.Wherein, there is no any restrictions, the above method especially to can be not only used for wave crest welding process
Welding, it can also be used to reflow soldering.It especially can also be in surface mount (SMD Surface Mounted Device) technology
Form the installable electrical overvoltage protective module of circuit board 1.
In addition, in the case where not limiting the generality of the present invention, it may also dictate that, in addition the overvoltage protective module 1 has
It is useful for the interface to report an error, the interface is used to cause to report when overvoltage protective module runs the installation tool ME not removed
It is wrong.This report an error also can be performed such that so that reporting an error for malfunction coefficient and/or over-voltage protection element is sent out when reporting an error.Thus may be used
Such as ensures to identify and be not intended to forget the installation tool ME of falling.
Under the premise of not limiting above-mentioned generality, the present invention can also add for the different application of overvoltage protective module 1
With application.It, can be for example using different over-voltage protection elements in order to cover different application fieldsTherefore, this hair
It is bright especially to have from transient voltage suppressor diode, varistor, positive temperature coefficient resistor or gas-discharge tube or fire
Selected at least one element in flower gap.
By above-mentioned overvoltage protective module 1, it will be able to cost not highly mounting circuit boards.
The installation method of the overvoltage protective module (1) is：The overvoltage protective module 1 is first by traditional installation quilt
It is installed on circuit board, then, the overvoltage protective module 1 is soldered to the electricity by one or more other parts
On the plate of road, wherein a variety of welding methods, especially reflow soldering and wave soldering can be used.Next, by side appropriate
Method step, for example mechanical extraction/pull-out and/or the dissolving by chemical mode/fall off, to remove the installation tool ME.
