Abstract
The utility model discloses a contact type automobile electric horn, wherein the part between a stationary contact (1) and a movable contact (2) of the electric horn is coated with a layer of lubricating grease (3), so as to eliminate open circuit caused by greasy dirt combustion and carbon deposit, and prevent phenomena that the contact surface oxidation leads to incapability of contact communication and the horn cannot work. The contact type automobile electric horn passes the newest national standard hundred-thousand time service life tests. The method of lubricating grease coating does not increase too much cost, therefore, compared with the traditional method of changing better and more expensive contact material, the method of lubricating grease coating saves more contact materials.
Description
Technical field
The utility model relates to a kind of chattering type electric automobile horn.
Background technology
The present chattering type electric automobile horn that uses, what its contacting adopted is clapper-type.When loudspeaker piped, the contact switched on and off and carries out work with the frequency of per second about 400 times, can cause the arcing phenomenon between the contact.Therefore, general technical requirement should keep clean between the loudspeaker contact, remove degreasing, otherwise greasy dirt burns under the arcing effect and forms carbon deposit.Its consequence not only can be quickened the electrocorrosion of contact, but also can cause opening circuit between the contact.So the present chattering type electric automobile horn that uses all is not oiling.But electric automobile horn is not to be operated in vacuum environment, and the contact all is metal, in case the high humidity of the environment of running car is added the influence of salt fog (as searchore etc.), the contact surface of chattering type electric automobile horn will produce oxidation.Because the oxide layer of contact surface is formed into certain thickness, and the contact can't be connected, and causes the idle fault of loudspeaker.For this reason, must seek a kind of solution.
Summary of the invention
The purpose of this utility model is: should eliminate because of opening circuit that the greasy dirt combustion deposits produce, prevent that again the contact that the contact surface oxidation causes from can't connect, cause not job failure of loudspeaker.
Technical solution of the present utility model is between the stationary contact and moving contact of chattering type electric automobile horn, to have applied one deck railway grease.This railway grease generally is to be used between the sliding contact, mainly is anti-oxidant, anticorrosion, plays good lubricated electric conductivity.Such as: homemade KG, KS series contact lubrication fat; Railway grease such as external EL series of producing, 2G series, NS series.
The fat layer that is coated in contact surface can not be too thick, the thick sounding that can have influence on loudspeaker.But can not be too thin, approached the effect of not having.For this reason, the thickness of fat layer should be about 0.5mm.
Through comparing, the fat that can better satisfy present electric automobile horn requirement is NS-1478-G, can guarantee the contact resistance that the contact faying face is little, good antirust and anti-corrosion capability.
A kind of chattering type electric automobile horn of the present utility model, because after having adopted the present technique solution, both eliminated because of opening circuit that the greasy dirt combustion deposits produce, prevented that again the contact that the contact surface oxidation causes from can't connect, cause the idle phenomenon of loudspeaker, passed through 100,000 durability tests of latest national standards.Owing to do not increase how many costs, only applied the special railway grease of one deck, this just than common employing replacing better, more expensive slider material will save many.

Fig. 2 is a kind of chattering type electric automobile horn of the utility model synoptic diagram.
The figure number explanation
1 ... stationary contact 2 ... moving contact 3 ... railway grease
Embodiment
As can be seen from Figure 2, between the clapper-type contact of forming by stationary contact (1) and moving contact (2), evenly be coated with NS-1478-G railway grease.
Claims (2)
1. a chattering type electric automobile horn is characterized in that: between stationary contact (1) and moving contact (2), applied one deck railway grease (3).
2. a kind of chattering type electric automobile horn according to claim 1 is characterized in that: the thickness that applies the fat layer is 0.5mm.
