Abstract
The utility model relates to an electronic horn with an insulation pad for vehicles. In traditional structures of motor vehicle electric horns, an electromagnetic switch consists of a steel piece, a spring piece, and an insulation piece, wherein electromagnetic forces are generated to drive horn diaphragms to vibrate through connection and disconnection of electromagnetic coils, so that electronic horns sound. The defects of the insulation piece are that horns are inconvenient to assemble, automatic assembly of horn production is difficult, and the service life of horns is reduced. The electronic horn with the insulation pad for vehicles comprises a housing (1), coils (2), a steel piece (3), a spring piece (5), a screw (4) and the insulation pad (6), wherein the coils (2) are arranged inside the housing, two ends of the steel piece (3) are fixed on the housing, one end of the spring piece (5) is fixed on the housing through the screw (4), the insulation pad (6) which is made of a ductile material is arranged on the spring piece in an injection molding mode, and the installation position of the insulation pad corresponds to moving armatures.
Description
Technical field:
the utility model relates to a kind of automobile electronic loudspeaker, is specifically related to a kind of electronic horn with insulating mat.
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 powder too much fly between the switch contact time, 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.
The utility model content:
The purpose of
the utility model is that the problem that is directed against above-mentioned existence provides a kind of automobile electronic loudspeaker with insulating mat, effectively solves short 2 problems of loudspeaker assembling trouble and serviceable life.
Above-mentioned purpose realizes through following technical scheme:
have the automobile electronic loudspeaker of insulating mat; Its composition comprises: housing; Coil is installed in described housing the inside, steel disc two ends be fixed on the described housing, an end of shell fragment through screw retention on described housing; Be injected with the insulating mat made from toughness material above the described shell fragment, the installation site of described insulating mat is corresponding with moving armature.
Beneficial effect:
The insulating trip in traditional horn switch (steel disc, shell fragment, insulating trip) has been saved in
1. the utility model electric horn construction of switch; 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 utility model has pasted the insulating mat of a toughness on shell fragment; At first, the insulating mat 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 insulating mat 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 insulating mat, 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 utility model 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 utility model adopt insulating mat to be processed in through injection molding way with shell fragment, guarantee the size of insulating mat, increase the life-span of product.
4, the utility model insulating mat are injection-moulded in shell fragment, have reduced installation procedure, have reduced cost.
Description of drawings:
accompanying drawing 1 is the structural representation of the utility model.
Embodiment:
Embodiment 1:
have the automobile electronic loudspeaker of insulating mat; 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, an end of shell fragment 5 is fixed on the described housing through screw 4; Be injected with the insulating mat made from toughness material 6 above the described shell fragment, the installation site of described insulating mat is corresponding with moving armature.
are as shown in Figure 1, and steel disc, shell fragment and insulating mat are formed the electromagnetic switch of loudspeaker.The two ends of steel disc and an end and the coil of shell fragment are fixed on the housing together, are pounded the insulating mat that a toughness has been pasted in the position of hitting by moving armature at horn spring plate.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 insulating mat is arranged.
Claims (1)
