Description
Technical field
It is a kind of breaking units of protector that the utility model relates to, particularly a kind of integrated circuit warning breaking units that is used for protector.Belong to security personnel's equipment technical field.
Background technology
Protector must meet the barrier propterty index in the industry standard.Again the overvoltage and the over-current protection criterion of acceptability of protector have been stipulated in the new industry standard, wherein require when power line touches that load is 40 Ω and 10 Ω in the test, the outside line input of protector should be opened a way and sent lasting visible alarm signal in 3 minutes.In existing protector, the failure protection device of most of protectors adopts low-melting alloy, utilizes this low-melting alloy melted by heat to make the slide mechanism action.Though these protectors can send lasting alarm signal when overvoltage/overcurrent; but because its internal structure is unreasonable; can not open a way the outside line input, even also existence abating protection device when fuse failure also has little time action, can not send the situation of alarm signal.At present, someone adopts the thermal deformation metal material to make the self-resetting type protector as the inefficacy material, as thrermostatic bimetal-plate, memorial alloy or temperature-sensitive magnet, utilize thrermostatic bimetal-plate temperature distortion or temperature-sensitive magnet reduced by thermomagnetion and form the action of threading off, allow d/d slide block back down the inlet wire shell fragment and make outside line input open circuit.Though they have overcome aforementioned protector can not be the deficiency of outside line input open circuit, have following shortcoming: the price of (1) thermal deformation metal material and temperature-sensitive magnet is higher, and cost is increased.(2) thermal deformation metal material and temperature-sensitive magnet profile are bigger, make the increase that takes up room is installed.In addition, double loop overcurrent overvoltage integrated circuit (IC) chip protector has begun to use in communication network with its particular performances, this kind protector mainly adopts the single integrated circuit chip to form, but because its volume is bigger, has limited its application in communications equipment room.
The utility model content
The utility model technical issues that need to address, i.e. the purpose of this utility model is for the integrated circuit warning breaking units that is used for protector that a kind of volume is little, cost is low is provided, this breaking units makes the volume of protector little, low cost of manufacture.
Technical problem of the present utility model can solve by taking following measure:
The integrated circuit warning breaking units that is used for protector, comprise housing, cover, its design feature is: can be provided with sliding unit body, elastic force apparatus, alarm reed, left inlet wire reed, right inlet wire reed, left outlet reed, right outlet reed, grounding reed and low-melting alloy in the housing; The sliding unit body can comprise integrated circuit (IC) chip, place in the slide, and the elastic force output of elastic force apparatus links to each other with the sliding unit body; The ground wire of sliding unit body links to each other with low-melting alloy, and low-melting alloy contacts with grounding reed; At the rear portion of sliding unit body, left inlet wire reed, right inlet wire reed, left outlet reed, right outlet reed are being pressed respectively and the input of sliding unit body, the contact point that output links to each other; The alarm reed at the sliding unit body to contacting with ground wire on the circuit printing plate after the front slide and being communicated with.
Problem of the present utility model can also take following measure to solve:
The sliding unit body can be made of circuit printing plate and two integrated circuit (IC) chip, and two integrated circuit (IC) chip are affixed on the and arranged on left and right sides face of circuit printing plate front portion symmetrically; End face in the circuit printing plate front portion, the ground wire of two integrated circuit (IC) chip contacts with low-melting alloy, and low-melting alloy heads on grounding reed again; At the rear portion of circuit printing plate, left inlet wire reed, right inlet wire reed, left outlet reed, right outlet reed are being pressed respectively and the input of two integrated circuit (IC) chip, the contact point that output links to each other.
Described elastic force apparatus is made of spring, and spring heads on the end face at circuit printing plate rear portion.
The number of described sliding unit body is two, three, four or five.
The input of aforementioned and two integrated circuit (IC) chip, the contact point that output links to each other are located at respectively on the side of the circuit printing plate at place separately.
The utlity model has following outstanding effect:
1, owing to adopts two single loop overcurrent overvoltage integrated circuit (IC) chip to be attached to the and arranged on left and right sides face of circuit printing plate symmetrically, the set contact point in circuit printing plate rear portion in turnover line reed and the sliding unit body joins, compact conformation, sliding unit body requisite space is very little, and the volume of breaking units is significantly reduced.Therefore the utility model can make the outside line input open circuit of protector and sent lasting visual alarm in 3 minutes when power line touches that load is 40 Ω and 10 Ω in the test.
2, the utility model is when protecting action; to front slide, the actuating mechanism of sliding unit body is made up of low-melting alloy, spring, sliding unit body itself under the elastic force effect of elastic force apparatus for low-melting alloy melted by heat, sliding unit body; actuating mechanism is simple in structure, occupies little space.The sliding unit body disconnects the input of connecting originally when sliding, and alarms in reed and the cell cube ground wire simultaneously and connect, input open circuit and send the problem of lasting alarm signal when having solved the protector protection.And, be the inefficacy material owing to adopted the lower low-melting alloy of price, reduced product cost.Because low-melting alloy can be done lessly, also helps reducing the installing space that takies.
