Abstract
The utility model relates to a kind of car horn binding post structure, comprise housing, be arranged on two binding posts in housing, in described housing, be also provided with placing chamber, be provided with in placing chamber be connected in parallel on two connect between fly-wheel diode, be filled with insulate heat gel in placing chamber.The utility model effectively can solve existing car horn and be subject to electromagnetic interference (EMI), be subject to the impact of outside uncontrollable factor and the problem that damages, and Stability Analysis of Structures is reliable, assembles easy, can be widely used in car horn construction applications.
Description
Technical field
The utility model relates to a kind of car horn binding post structure.
Background technology
Automobile basin-shaped electric horn be one operationally, because of its switching and produce electric arc repeatedly, thus produce strong electromagnetic disturbance at the wiring two ends of electric horn.This electromagnetic disturbance can cause severe jamming to other electric equipment products Source Musics, engine management system, ABS system etc. on automobile, and the car load directly affecting automobile runs.
In the electric horn course of work, power supply by electric horn breaker point unit contacting loudspeaker circuit, and produces magnetic field through contact to coil electricity.Under the effect of the electromagnetic force of magnetic field generation, armature is attracted, and armature band dynamic diaphragm, sounding board move downward.Meanwhile, armature has also pulled lower contact arm downwards, upper and lower contact is disconnected, has cut off circuit.After coil blackout, electromagnetic force disappears, and armature discharges, and diaphragm and lower contact arm reset.Now upper and lower contact closes, and power supply produces magnetic field through contact to coil electricity again, repeats said process, vibrational system air of reciprocating vibration and sounding.
The moment that contact disconnects in the electric horn course of work can produce electric arc, electric horn coil will produce back-emf due to the characteristic of inductance, so produce the pulse voltage (or claiming electromagnetic disturbance) that amplitude is very large, pulsewidth is very narrow, frequency spectrum is very wide at electric horn binding post two ends.Therefore, during electric horn breaker point unit contacting, the impulsive disturbance of generation will seal in other equipment (Source Music, controller etc.) along wire and cause electromagnetic interference (EMI).Therefore the binding post of electric horn is harassing and wrecking sources.
Utility model content
The purpose of this utility model is to provide a kind of car horn binding post structure, solves existing car horn and is subject to electromagnetic interference (EMI), is subject to the impact of outside uncontrollable factor and damages, the problem that structure is reliable and stable not.
The utility model solves the technical scheme that its technical matters adopts: a kind of car horn binding post structure, comprise housing, be arranged on the binding post in housing, also placing chamber is provided with in described housing, be provided with the fly-wheel diode being connected in parallel on binding post two ends in placing chamber, in placing chamber, be filled with insulate heat gel.
In order to ensure that positive and negative electrode is isolated, circuit is more reliable, and described placing chamber comprises for settling the resettlement groove of fly-wheel diode and two the cylindricality through holes being arranged on resettlement groove two ends; Two cylindricality through holes are respectively used to the positive and negative electrode connecting line placing fly-wheel diode and binding post.
In order to make fly-wheel diode contact closely with binding post, described fly-wheel diode is wrapped on the arm of binding post periphery.
In order to make anti-electromagnetic interference capability better, described fly-wheel diode is fast recovery diode.
The beneficial effects of the utility model: the not sensed electromotive force of fly-wheel diode protection element punctures or burns out; respond to binding post two ends in parallel; namely the element two ends of electromotive force have been connected in parallel on; and with its formation loop; the high electromotive force making it produce consumes with continuous current system in loop, thus suppresses inverse electromotive force to the interference of other equipment.Be filled with insulate heat gel in placing chamber, strengthen the reliability of binding post structure, prevent the destruction of outside uncontrollable factor, and affect the performance of product.
The utility model effectively can solve existing car horn and be subject to electromagnetic interference (EMI), be subject to the impact of outside uncontrollable factor and the problem that damages, and Stability Analysis of Structures is reliable, assembles easy, can be widely used in car horn construction applications.
Below with reference to drawings and Examples, the utility model is described in detail.
