Abstract
A kind of overheated overcurrent protector; the attemperating unit of series connection and heating wire are accessed circuit; when device temperature is too high, attemperating unit disconnects and cuts off circuit; and heating wire generates heat and promotes attemperating unit to disconnect when electric current is excessive; while there is the internal base for arranging stepped concave station; both are combined into one; so as to reducing its volume, simplifying circuit and improve the convenience of equipment installation; while stair-stepping setting can also effectively ensure both job stability and accuracys; the simple structure, effectively, and with low cost and be easily achieved.
Description
Technical field
The present invention relates to a kind of while preventing circuit temperature too high and the excessive overheated overcurrent protector of electric current.
Background technology
Overheat protector is installed in circuit, and when circuit is overheated, its internal circuit disconnects, so as to disconnect whole piece loop,
Prevent circuit overheated and break down.Overcurrent protector is similarly installed in circuit, when the magnitude of current in circuit exceeds setting value
When, its internal circuit disconnects and cuts off whole piece loop, prevents electric current excessive and contingency occurs.Both circuit brakes divide
Overtemperature protection and overcurrent protection An Zhuan can not be carried out respectively to circuit among circuit, but this is needing among circuit
Set two installation sites respectively, cause complex circuit, difficult in maintenance；Two needing to increase a plurality of electric wire, causes the increasing of cost
Plus；Three also causing the volume of equipment accordingly must increase, and in circuit brake field, the equipment of excessive bulk is difficult to transport
For in multiple product, so not only increased cost but also affected its scope of application.
Content of the invention
The present invention is intended to provide a kind of overheated overcurrent protector that circuit can be prevented simultaneously overheated with excessively stream, to simplify line
Road, reduces cost and equipment volume, improve its scope of application.
Overheated overcurrent protector of the present invention, including the electricity generated heat after the attemperating unit being opened and closed with temperature, and energising
Heated filament, has inside to have the base of stepped concave station, and, in lower floor's ladder of concave station, attemperating unit is installed in recessed for heating wire
On the upper strata ladder of platform, an electrode on attemperating unit and one end of heating wire are electrically connected, another electricity of attemperating unit
The other end of pole and heating wire connects external circuit respectively.
Overheated overcurrent protector of the present invention, attemperating unit and heating wire series connection, then be integrated by base combination,
One end of one electrode of attemperating unit and heating wire is connected with circuit respectively, is connected as with circuit and required equipment to be protected
One loop.During work, electric current flows through attemperating unit and heating wire successively along circuit, when device temperature or running temperature too high
When, attemperating unit disconnects, and plays a part of temperature protection；And when circuital current is excessive, electrothermal wire heating simultaneously affects temperature control
Device makes its disconnection, that is, play a part of overcurrent protection.Mainly using the temperature control principle of attemperating unit, which ties the protector
Structure is simple, effectively, with low cost and be easily achieved；Attemperating unit and heating wire are connected as one by base, simple by this kind
Structure can greatly reduce complexity and the maintenance difficulties of circuit, while reduces cost and reduction equipment volume, expand which
Range；Chassis interior is provided with stair-stepping concave station, and attemperating unit and heating wire are separately mounted to the upper and lower ladder of concave station
Interior, the stability of its work was both can ensure that, both directly contacts can have been avoided again, so as to cause changing for heating wire setup parameter
Become or heating wire causes attemperating unit to work because transmission heat is excessive in the state of low current, effectively ensure its work
Stability and accuracy.

Specific embodiment
A kind of overheated overcurrent protector, including the heating wire 2 generated heat after the attemperating unit 1 being opened and closed with temperature, and energising, has
Inside has the base 4 of stepped concave station 3, and, in lower floor's ladder of concave station, attemperating unit is installed in concave station for heating wire
On the ladder of upper strata, an electrode on attemperating unit and one end of heating wire are electrically connected, another electrode of attemperating unit and
The other end of heating wire connects external circuit respectively.
Connector 6 outside attemperating unit box body is protruded from equipped with connection terminal 5 and slightly on attemperating unit 1, connection terminal connects
Connect an electrode and the external circuit of attemperating unit, connector connection another electrode of attemperating unit and one end of heating wire 2；
Base 4 is provided with terminal base 7 and pin base 8, and terminal board 9 is fixed in terminal base and connects one end and the connector of heating wire 2
6, pin 10 is fixed on pin base and connects external circuit.Connection terminal on attemperating unit can with the plate of external circuit,
The parts such as pin conveniently realize electrical connection, and connector is slightly protruded from outside box body, on the basis that satisfaction is connected with terminal board
On can effectively reduce its equipment volume., within the concave station of base, its terminal board for passing through outside can be square for heating wire
Just, stably connect attemperating unit；And the setting of pin equally simply and easily can be connected with external circuit, its peace can be improved
Dress convenience and reduction maintenance difficulties.
Can be bonding by point glue between attemperating unit 1 and base, can also be connected with snap fit, or alternate manner connection
It is integrated, currently preferred using point glue bonding, the attachment structure is simple and consolidates enough, in maintenance process also extremely
It is easy to assemble and disassemble work.
Attemperating unit 1 includes attemperating unit box body 11, and attemperating unit box body is built with the static contact being connected with circuit respectively
Component 12 and movable contact spring component 13, the bimetal leaf 14 of also temperature distortion, top is provided between bimetal leaf and movable contact spring component
Bar 15, movable contact spring component are electrically connected with static contact component under bimetal leaf undeformed state, by top after bi-metal plate deformed
Masthead plays movable contact spring and makes which disconnect the connection with static contact component；The top that attemperating unit also has capping 16, capping 16 has
