The utility model is characterized in that the circuit board is provided with an absorbing circuit, a bridge rectification circuit, an electronic switch circuit, and a detecting triggering circuit; the utility model is characterized in that the voltage of the both ends of an absorption capacity is always less than the voltage of a power supply without interference of peak pulse; when the interference of peak pulse appears, the absorption capacity is connected in a circuit in parallel, forming enough charging (bleeder short circuit) current; thus, most of the voltage of the peak pulse has short circuit to ground by the capacitance instantaneously.
Description
Absorb the supply socket of spike, belong to electric type.Can be applicable in the AC power absorption to the spike disturbing pulse of transition.
Existing power-supply filter is the π type low pass filter that inductance and electric capacity are formed, this filter is for the High-frequency Interference pulse, particularly the above broadband interference noise of 20KHZ has stronger inhibition ability, but when this filter hangs down for spike interference voltage frequency, when particularly being lower than the 20KHZ left and right sides, its inhibition ability obviously weakens.This mainly is that it is too big to make inductance and capacitance not to obtain, thereby makes the filter effect variation because of factors such as volume, weight and costs, and the disturbing pulse frequency is when low more, and filter effect is poor more.
The purpose of this utility model:, improve the power filter effect, the supply socket of ad hoc this absorption of meter spike for solving of the interference of low frequency spike disturbing pulse to power supply.
Solution of the present utility model is: the supply socket that absorbs spike comprises: jack housing, absorb spike circuit board two large divisions, and the impulse circuit plate is contained in the jack housing the inside, it is characterized in that: absorb absorption circuit (1) is housed on the spike circuit board, bridge rectifier (2), electronic switching circuit (3) detects circuits for triggering (4), absorbs circuit (1) by capacitor C

Advantage of the present utility model: the voltage at general filter capacitor two ends is always along with the sinusoidal voltage of power supply changes and changes, and the voltage at the filter capacitor two ends in the supply socket of absorption spike approximates the O volt, have only when spike disturbs arrival, could be with the filter capacitor place in circuit, form the charging current of a false short circuit, sponge so that spike is disturbed; The utility model is more flexible with the form of socket, can directly incorporate into to absorb on the interference source and disturb, and than being connected in the prior art in the circuit, seems flexible; The utility model purposes is wide, can be used for computer, industrial computer plays anti-interference effect, and the protection of also available and high-grade household electrical appliance absorbs the medium and low frequency spike and disturbs.
Further specify the utility model below in conjunction with accompanying drawing.

Narrate the course of work below: when not having the stack spike on the sine wave, C
1The big both end voltage of capacity is about 0 volt, and the equal pressure drop of sinusoidal voltage is at bridge rectifier (2) D

4After electronic switching circuit (3) and detect a, the b two ends of circuits for triggering (4), the electric current R that flows through

3And W.C
3Equal the voltage stabilizing value of W voltage-stabiliser tube after the charging of two ends, and the voltage stabilizing value of W approximates (being slightly less than) D
6So the triggering breakover voltage value of diac is D
6Do not work, again because of the R resistance is bigger, so the voltage of a, b end is continuous half-wave voltage basically.
When the stack spike appears in sine wave, disturb immediately by C
1Through D
1-D
4Be coupled to a, b end, the spike interference voltage passes through C
2When flowing through L, because of L produces very strong induction reactance, and the L two ends produce very strong on negative just down electromotive force, this voltage is superimposed upon W and C
3On voltage on, when this voltage exceeds D
6Breakover voltage the time and make controllable silicon T conducting, D
6After the conducting, C
3On voltage pass through D
5Rapidly to D
6Quicken discharge, until the part that is former institute charging voltage, to guarantee the reliable conducting of controllable silicon.At this moment, short circuit is approached at a, b two ends, is actually a C
1Be connected in parallel in the power circuit, because of the electric capacity both end voltage can not be suddenlyd change, so big of peaking voltage by electric capacity instantaneous be shorted to ground.
In a word, characteristics of the present utility model are: when no spike interference occurred, the voltage that absorbs the electric capacity two ends was always less than supply voltage, when the spike interference occurs, C absorbs electric capacity and is parallel in the circuit, forms enough chargings (short circuit of releasing) electric current.
The inventor is by experimental results demonstrate; When filter capacitor was 4.7 μ f, interference can reduce by 30%～50% to the spike about 200 μ s, if adopt high speed element and select respective absorption electric capacity for use according to interfering frequency, effect is better.…
The utility model is implemented to be not difficult, and the electronic devices and components buyable assembles.
