One side of the fixed plate is equipped with at least one first wiring terminal, and the other side of the fixed plate is equipped with at least one second wiring terminal. One first wiring terminal and one first wiring terminal are in one group. The fixed plate is equipped with at least one fuse tube box. Each fuse tube box is equipped with a fuse tube. The other sides of the fixed plate and the fuse tube box are equipped with a diode or a capacitor and a resistor or a varistor. According to the anti-interference device with a fuse tube, while an inductive load it effectively controlled to cause transient voltage and higher harmonic in the process of power on and power off, the short circuit protection of the load can be carried out.
Description
Technical field
The utility model relates to electric equipment products, is a kind of suppressor with protective tube.
Background technology
Suppressor is widely used in the electric control system of numerical control, PLC control system and various electronic circuits.Suppressor can effectively be controlled instantaneous pressure and the high order harmonic component that inductive load causes in switching electric process, thereby further guarantees safety, the reliability service of electric-control system.Suppressor has resistance-capacitance absorption type, fly-wheel diode type, piezoresistive and piezo-resistance+resistance-capacitance absorption type; though these suppressors have corresponding advantage; but; equal Shortcomings: in instantaneous pressure and high order harmonic component that effectively control inductive load causes at switching electric process, can not carry out short-circuit protection to inductive load.
Utility model content
The purpose of this utility model is, a kind of suppressor with protective tube is provided, and makes it when reaching effective control inductive load cause instantaneous pressure and high order harmonic component in switching electric process, can carry out short-circuit protection to load.
The purpose of this utility model is achieved through the following technical solutions: with the suppressor of protective tube, comprise housing, the upper surface mounting plate of housing, fixed head one side is at least installed first binding post, fixed head opposite side is at least installed second binding post, first binding post and second binding post are one group, a protective tube box is at least installed on fixed head, equal installation insurance pipe in each protective tube box, on fixed head, the opposite side of protective tube box installs diode or electric capacity and resistance or piezo-resistance.On fixed head, a side of protective tube box installs the first resistance, protective tube box one side diode installed, light-emitting diode is connected with the first resistance.After the series connection of described light-emitting diode and the first resistance with protective tube parallel connection, connect with electric capacity and the second resistance again.After the series connection of described light-emitting diode and the first resistance with protective tube parallel connection, connect with piezo-resistance again.After the series connection of described light-emitting diode and the first resistance with protective tube parallel connection, connect with fly-wheel diode again.In parallel with protective tube after described light-emitting diode and the series connection of the first resistance, more in parallel with piezo-resistance again after connecting with the second resistance with electric capacity, after being connected with the first resistance, protective tube connects with being connected to of piezo-resistance and electric capacity.Described the first binding post and the second binding post are two linearly type arrangements above respectively, and protective tube box is two linearly type arrangements above.
The utility model has the advantage of: when completing the instantaneous pressure and high order harmonic component that effective control inductive load causes in switching electric process on suppressor product, inductive load is carried out to short-circuit protection; Make suppressor account for control cubicle inner area little; User only need directly access suppressor by the inlet wire of controller, and outlet is directly connected with load by suppressor, thereby saves user's workload, reduces the error rate in user job, and can shorten manufacture set-up time etc. of piece electrical system.
