Abstract

A kind of impulse train special filter based on IEC standard, it is characterized by comprising shells, socket is equipped in the side of shell, several pins are equipped in the other side of shell, the pin includes L wire pin, GND pin and N wire pin, and level-one filter module and secondary filter module are equipped in shell；By the socket and pin access power supply and equipment on shell, remove the impulse disturbances in equipment；Signal is repeatedly handled by the intracorporal level-one filter module of shell and secondary filter module, effectively eliminates impulse disturbances, the normal starting of equipment is also can guarantee, makes device replied to normal operating conditions, with high security, good wave filtering effect the advantages of.

Description

A kind of impulse train special filter based on IEC standard

Technical field:

The utility model relates to a kind of impulse train special filter based on IEC standard.

Background technique:

The filter circuit that filter is made of capacitor, inductance and resistance is common electrical member in electric and electronic industry Part.

Filter can the frequency other than the frequency point or the frequency point to specific frequency in power supply effectively filter out, obtain one The power supply signal of a specific frequency, or eliminate the power supply signal of a specific frequency, reduce signal in generation, convert, be transmitted across The interference being subject in journey, the precision of promotion signal transmission.

Equipment increases impulse disturbances, it may appear that power-off restarting phenomenon, after impulse disturbances are eliminated, in the effect of existing filter Under, only by being once filtered, device systems can not normally start, and cannot be returned to normal operating conditions.

Utility model content:

The utility model in order to make up for the deficiencies of the prior art, provides a kind of dedicated filter of the impulse train based on IEC standard Wave device, reasonable in design, multiple filter modules enter working condition, can make equipment that can return after impulse disturbances elimination Normal operating conditions is arrived again, is provided protection to equipment, is effectively eliminated impulse disturbances, lifting means performance solves the prior art The problem of.

Used technical solution is the utility model to solve above-mentioned technical problem:

A kind of impulse train special filter based on IEC standard, including shell are equipped with socket in the side of shell, in shell The other side of body is equipped with several pins, and the pin includes L wire pin, GND pin and N wire pin, and one is equipped in shell Grade filter module and secondary filter module.

The pin is gold-plated contact pin.

The level-one filter module includes the one group of inductance and two groups of capacitors being electrically connected.

The secondary filter module includes the two groups of inductance and two groups of capacitors being electrically connected.

The utility model using the above structure, by the socket and pin access power supply and equipment on shell, removes equipment On impulse disturbances；Signal is repeatedly handled by the intracorporal level-one filter module of shell and secondary filter module, effectively eliminates arteries and veins Punching interference, also can guarantee the normal starting of equipment, makes device replied to normal operating conditions, with high security, filter effect Good advantage.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the structural schematic diagram of the level-one filter module of the utility model.

Fig. 4 is the structural schematic diagram of the secondary filter module of the utility model.

In figure, 1, shell, 2, socket, 3, L wire pin, 4, GND pin, 5, N wire pin, 6, level-one filter module, 7, two Grade filter module.

Specific embodiment:

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

As shown in figs. 1-4, a kind of impulse train special filter based on IEC standard, including shell 1, the one of shell 1 Side is equipped with socket 2, is equipped with several pins in the other side of shell 1, the pin includes L wire pin 3, GND pin 4 and N line Pin 5 is equipped with level-one filter module 6 and secondary filter module 7 in shell 1.

The pin is gold-plated contact pin.

The level-one filter module 6 includes the one group of inductance and two groups of capacitors being electrically connected.

The secondary filter module 7 includes the two groups of inductance and two groups of capacitors being electrically connected.

In use, filter is accessed power supply and equipment by the socket 2 and pin that pass through on shell 1, the first-level filtering in shell 1 Wave module 6 and secondary filter module 7 handle signal, solve the impulse disturbances in equipment, repeatedly filter, effectively eliminate filter Wave interference；Pin is gold-plated contact pin, and conduction property is good, can restore normal operating conditions after restarting equipment；Level-one filter module 6 For one group of inductance and two groups of capacitors, secondary filter module 7 is two groups of inductance and two groups of capacitors, is filtered step by step, highly-safe, filtering Device performance is good, efficiently solves the problems, such as the impulse disturbances in equipment.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
