Abstract
The utility model relates to an automotive electronic horn with an insulating ring. The traditional structure of the electronic horn of the motor vehicle is always as follows: an electromagnetic switch is composed of a steel sheet, an elastic sheet and an insulating sheet and used for switching on and off an electromagnetic coil, and generating an electromagnetic force to drive a horn diaphragm to variable, thus enabling the electronic horn to make a sound. The insulating sheet has the defects that assembly for the horn is troublesome, the difficulty of automatic assembly in production for the horn is increased, and the service life of the horn is decreased. The composition of the automotive electronic horn with the insulating ring disclosed by the utility model comprises a shell (1), wherein a coil (2) is installed in the shell; the both ends of a steel sheet (3) are fixed on the shell; one end of an elastic sheet (4) is fixed on the shell via a bolt (5); a moving armature (6) is installed in the shell; an insulating ring (7) made from a flexible insulating material is installed on the moving armature; and the insulating ring on the moving armature is contacted at a position corresponding to the elastic sheet. The automotive electronic horn with the insulating ring disclosed by the utility model is used as an automotive horn.
Description
Technical field:
the present invention relates to a kind of automobile electronic loudspeaker, are specifically related to a kind of electronic horn with dead ring.
Background technology:
The traditional structure of
electric horn of motor vehicle all is by steel disc, shell fragment, and insulating trip is formed electromagnetic switch, makes the solenoid break-make, produces electromagnetic force and drives the vibration of loudspeaker diaphragm, thereby electric horn is sounded.The shortcoming of this insulating trip is to make loudspeaker assembling trouble, and the robotization assembling of producing to loudspeaker increases difficulty, and it has also reduced the serviceable life of loudspeaker simultaneously.Reason be this insulating trip in the switch motion of loudspeaker because moving armature is pounded at a high speed and hit, it will sputter a lot of powder granulated slags.These powder granulated slags all are megohmite insulants, when they are too much when flying between the switch contact, will make switch not to be switched on again.Loudspeaker have just lost original function like this, and also will finish the serviceable life of loudspeaker.
Summary of the invention:
the objective of the invention is to the problem of above-mentioned existence a kind of automobile electronic loudspeaker with dead ring to be provided, and effectively solve short 2 problems of loudspeaker assembling trouble and serviceable life.
Above-mentioned purpose realizes through following technical scheme:
have the automobile electronic loudspeaker of dead ring; Its composition comprises: housing, coil is installed in described housing the inside, steel disc two ends be fixed on the described housing; One end of shell fragment passes through screw retention on described housing; Moving armature is installed in described housing the inside, and the dead ring that the toughness insulating material is made is installed on the described moving armature, and dead ring is in the position contact corresponding with described shell fragment on the described moving armature.
Beneficial effect:
The insulating trip in traditional horn switch (steel disc, shell fragment, insulating trip) has been saved in
1. the present invention, if but do not had insulating trip, the loudspeaker moving armature is pounded and has just been produced electrical connection when hitting shell fragment, causes power supply short circuit, and this is unallowed.Therefore do not produce electrical connection in order moving armature to be pounded hit horn spring plate, the present invention pastes a dead ring on the moving armature of loudspeaker, and this dead ring is attached to moving armature and shell fragment position contacting, is that the insulating material by toughness constitutes.At first, the dead ring of this toughness has not only been accomplished the original insulating trip function of loudspeaker, and makes the assembling of loudspeaker simpler; Secondly, the used material of such dead ring is few, with low cost; At last owing to selected the insulating material of toughness for use, so improved pounding property and with the stationarity of shell fragment, pound when moving armature and can not produce the powder granulated slag when hitting dead ring, avoided megohmite insulant to fly between the contact of horn switch.Just can not cause switch failure yet, prolong the serviceable life of loudspeaker.
2, the present invention adopt the high performance nylon material, have wear-resisting and resistance and high temperature resistance property, have reduced the failure risk of loudspeaker.
3, the present invention adopt dead ring to be processed in through injection molding way with moving armature, guarantee the size of dead ring, increase the life-span of product.
4, dead ring of the present invention are injection-moulded in moving armature, have reduced installation procedure, have reduced cost.
Description of drawings:
accompanying drawing 1 is a structural representation of the present invention.
Embodiment:
Embodiment 1:
have the automobile electronic loudspeaker of dead ring; Its composition comprises: housing 1, coil 2 is installed in described housing the inside, steel disc 3 two ends be fixed on the described housing; One end of shell fragment 4 is fixed on the described housing through screw 5; Moving armature 6 is installed in described housing the inside, and the dead ring 7 that the toughness insulating material is made is installed on the described moving armature, on the described moving armature dead ring with contact in the corresponding position of described shell fragment.
are as shown in Figure 1, and steel disc, shell fragment and dead ring are formed the electromagnetic switch of loudspeaker.The two ends of steel disc and an end and the solenoid of shell fragment are fixed on the housing together.On the moving armature of loudspeaker, paste a dead ring, this dead ring is attached to moving armature and shell fragment position contacting.Pound when hitting shell fragment when moving armature,,, realized the break-make of solenoid, drive the vibration of loudspeaker diaphragm, electric horn is sounded thereby produce electromagnetic force so can not produce electrical connection because the existence of dead ring is arranged.
