Description

A kind of low-power consumption multi-terminal side-plug-in combines two devices

Technical field

The utility model is related to electronic device fields, and in particular to a kind of low-power consumption multi-terminal side-plug-in combines two devices.

Background technology

Compressor can be all used in the household electrical appliance such as air-conditioning, refrigerator, in general, compressor all include protector and Starter.It will be used when compressor start to starter, starter is generally all internally provided with bootrom, to adjust The size of current of starting state and operating status；And the effect of protector is then that the change of electric current is detected during compressor use Change, when electric current is excessive, protector disconnecting circuit, protecting the element of compressor, there is a situation where short circuit etc. is burned out.

In the prior art, thermal protector and starter are separately mounted to as two modular units on compressor, and And need to run wires to capacitance, process is complex, and material cost is also higher.Protector be segmented into again round protector and Two class of flat protector, since the structure space of compressor installation protector and starter is special, position is also very narrow, in order to This space is coordinated to set, what is used in the market is all that the round protector of starter cooperation is installed and used.Flat protector is difficult It installs and is used cooperatively jointly with starter.However, flat protector compares round protector, volume smaller, temperature sense is also more It is sensitive.

On the other hand, existing terminal is often arranged on the upper surface of two devices combination unit, and terminal needs connecting circuit All other routes, then this connection procedure need worker hand-manipulated.And in actual use, the upper surface of two devices combination unit Narrow space, operation due to lack operating space, it is very inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of low-power consumption multi-terminal side-plug-in and combines two devices, simple in structure, conducive to reality It applies, all parts structure is improved so that flat protector can be mounted on starter, in addition, each terminal setting side It is lateral to being changed to, improve operating space.

The above-mentioned technical purpose of the utility model technical scheme is that：A kind of low-power consumption multi-terminal Side-plug-in combines two devices, comprising main casing, also includes protector and starter, the protector is flat protector, described Protector is located above the starter, and also comprising terminal jacks, the starter is equipped with terminal jacks one and terminal jacks Two, the protector is equipped with terminal jacks three；The main casing is equipped with holding tank, and the protector side is equipped with to insert Enter the fixation inserted sheet in the holding tank；Also comprising multiple terminals, multiple terminals are located at the protector and the startup The side of device, side surface direction of the extending direction for the protector and the starter.

As the preferred of the utility model, the terminal jacks one and the terminal jacks two are offset to institute in the horizontal direction The center line of starter is stated, the terminal jacks three are offset to the center line of the protector in the horizontal direction.

Three terminal jacks are all offset to the center line of respective component, are connect for the terminal with compressor.It is and described Fixed inserted sheet is located at the side of the protector, is connect with the main casing at both ends, specifically, be inserted into the holding tank, Such connection mode causes flat protector and the space availability ratio higher of the combination of the protector.

And multiple terminals are used for each circuit of connecting circuit.For example, for refrigerator product, different refrigerators is connected Control circuit, such as light bulb, temperature switch, fan etc..

As the preferred of the utility model, the terminal is installed on the main casing, and close positioned at the main casing On the side of the terminal jacks.

The side design of the terminal, either position are also directed towards, all for side, having advanced optimized space availability ratio, It is supplied to the more operating spaces of worker.

As the preferred of the utility model, main electrode, double that the starter includes master chip, connect with the master chip It is also connected with to the silicon-controlled and connection bidirectional triode thyristor and the circuit board of the main electrode, the circuit board by auxiliary electrode Secondary chip.

As the preferred of the utility model, the pair chip volume is respectively less than the master chip with power.

In electric appliance, such as during refrigerator startup, the master chip and the secondary chip are all connected in circuit, and two chips are all Can be PTC thermistor, the transient current of startup is big, and two thermistor temp raisings, resistance value becomes larger so that electric current Reduce, so as to reach each circuit element of protection, the function of clean boot.Subsequently, as the electric current by the bidirectional triode thyristor Value is changed, and the bidirectional triode thyristor by circuit board is connect with the master chip, passes through the bidirectional triode thyristor Curent change cause its shutdown, at this point, the master chip is no longer powered, only by the secondary chip, entire circuit leads to circuit It crosses the secondary chip and continues conducting and work on, such setting under the construction of original starter, is connected to one The secondary chip and a bidirectional triode thyristor of small size forms a control loop, and the electric current for passing through control loop becomes Change that bidirectional triode thyristor is turned off, the master chip no longer energization nature will not generate power consumption, so as to reach the mesh of low-power consumption 's.

In general, the power consumption of the master chip is in 2W or so, and the power consumption of the pair chip is in 0.4W or so.

In conclusion the utility model has the advantages that：

1st, flat protector is inherited, improves temperature sensitivity.

2nd, protector is connected on a main housing by fixed inserted sheet.

3rd, terminal either position is also directed towards, all for side, having advanced optimized space availability ratio.

4th, main electrode protection arc abutting portion, the scuffing to chip is reduced in assembling process, increases making for chip Use the service life.
