Abstract
The utility model discloses an inhibitor for the sparking plug cap of a motorcycle. The utility model is characterized in that an inductance inhibitor is arranged on the bakelite sleeve of a casing, and a metallic shield cover is additionally arranged on the outer side of a rubber sleeve. The utility model gets no influence of the temperature. The utility model has the same resistance value as in room temperature in the high temperature of 80 to 120 DEG C. The higher the frequency is, the larger the resistance value of the inductance coil is, the better the inhibiting effect on the electromagnetic interference of the wide band is. The utility model meets the Chinese Standard admissible value proved by the arrangement on motorcycles of multiple models.
Description
The utility model is a kind of electromagnetic interference eliminator that motorcycle when operation produces during by plug ignition that suppresses.
Existing motorcycle spark plug cap mostly is the resistor plug cap, it is by the bakelite sheath and be located at the outer rubber layer of bakelite sheath and form the spark plug cap housing, one resistance of mainly being made by the carbon ink material is housed in the bakelite sheath of housing, one end of resistance can touch spark plug by a sheet metal, and the other end of resistance is connected with lead by behind the metal screw.When moving, motorcycle easily produces the temperature of wide band electromagnetic interference and spark plug cap up to 80-120 ℃, this moment, the resistance of this resistance can descend significantly, often 5 kilohms resistance can be reduced to tens ohm, owing to produce the interference of ground electromagnetism when the decline of resistance makes it not suppress plug ignition effectively, therefore existing spark plug cap does not almost all reach the permissible value of GB regulation.
The purpose of this utility model is to provide a kind of new motorcycle spark plug cap inhibitor, and it can suppress the motorcycle electromagnetic interference that plug ignition produces when operation effectively.
The technical solution of the utility model is achieved in that motorcycle spark plug cap inhibitor, it comprises by the bakelite sheath and is arranged on the spark plug cap housing that the outer rubber jacket layer of bakelite sheath is formed, it is characterized in that: an inductance inhibitor is housed in the bakelite sheath of housing, has added a metallic shield at the rubber jacket layer.
The utility model is owing to be equipped with an inductance inhibitor in the bakelite sheath of spark plug cap housing, also be added with a metallic shield outside the rubber jacket layer outside sheath, so the inhibition of the interference that produced by plug ignition when motorcycle is moved of the utility model divided for two steps implemented.When the first step, the high-frequency electromagnetic that produces when plug ignition were disturbed through the inductance type inhibitor, the inductance type inhibitor was equivalent to a high frequency filter, and it has played the effect of filter, and the electromagnetic interference that absorbs is outwards distributed in the mode of heat energy; Second step, remaining electromagnetic interference is through outer field metallic shield after process inductance type inhibitor, metallic shield and the inductance type inhibitor of this moment are similar to a shunt capacitance, particularly high more in frequency, the capacitive reactance of this shunt capacitance is low more, easy more this shunt capacitance of process of the electromagnetic interference signal of high frequency.Through the inhibition of these two electromagnetic interference that go on foot, the high-frequency electromagnetic interference source that has produced when having reached thorough consumption by plug ignition.
The utility model is in actual service testing, altogether on 29 kinds of various types of motorcycles of entrucking, product supervision inspection center test through State Bureau of Technical Supervision's approval, all meet the permissible value of IEC/CISPR12 publication, GB14023-92 regulation, it has the good inhibition effect of the electromagnetic interference that produces when suppressing the motorcycle plug ignition.The electromagnetic interference that plug ignition produced when the utility model inhibitor can suppress the motorcycle operation in the contrastive test on the XF125T motorcycle in the 30-1000MHZ frequency range is 40-60dB.29 kinds of all kinds, load onto the permissible value that the utility model inhibitor all meets IEC/CISPR12 publication, GB14023-92 regulation on the motorcycle of various models.

Fig. 2 is the inductance inhibitor structural representation among Fig. 1
The utility model will be further described below in conjunction with drawings and Examples
The utility model comprises by bakelite sheath 3 and is arranged on the spark plug cap housing that bakelite sheath 3 outer rubber jacket layers 2 are formed, it is different from prior art: an inductance inhibitor 4 is housed in the bakelite sheath 3 of housing, this inductance inhibitor adopts the two ends of the inductance coil 6 on the porcelain rod 5 to be separately fixed on metal joint 7 and the metal screw 8, link to each other with spark plug by metal joint 7 places again, general employing is directly inserted spark plug and is got final product, metal screw 8 places can link to each other with high-voltage conducting wires, lead can directly screw in and cutting ferrule metal screw, the inductance coil of inductance inhibitor is a nichrome wire in force, on the porcelain rod around the 200-300 circle, the spacing of every turn-to-turn is 0.02-0.06mm, can not collide, the two ends difference butt-joint of nichrome wire is on two nichrome caps 9, one nichrome cap 9 is fastened in the brass female fitting, and another nichrome cap 9 is fixed on the brass self-tapping screw; It is that the nichrome wire of 0.03mm is spaced winding 260 circles on the porcelain rod of 4.3mm at diameter that inductance coil among the embodiment adopts diameter, the turn-to-turn spacing is about 0.03mm, the machined into moulding of brass four joints, so that join with the threaded end regions of spark plug, the brass self-tapping screw also forms with machined into, can spin with the copper core of high-voltage conducting wires; Rubber jacket layer outside the bakelite sheath has added a metallic shield 1, and this metallic shield adopts stainless steel material to make, and is similar to be drum shape.
The electromagnetic interference that produces during in sum owing to the motorcycle plug ignition is a broad-band interference source, and general pure resistance type spark plug cap is when suppressing the wide band magnetic disturbance, and one is subjected to the influence of working temperature, can not disturb by the good restraining spark; The 2nd, be subjected to the influence of frequency, when low-frequency range, electromagnetic interference is had certain inhibition effect, when high band because the influence of working temperature and frequency, no good interference suppressioning effect.And the utility model adopts the rich inductive impedance of making of the nichrome wire of high value, is not subjected to Temperature Influence, when 80-120 ℃ of high temperature, still has the resistance value of normal temperature; And the resistance value of inductive loop is big more when frequency is high more, and wide band electromagnetic interference is had good inhibition effect.Simultaneously, add the radome made from metal material (corrosion resistant plate), be equivalent to a shunt capacitance in high-frequency circuit, the capacitive reactance of high more this shunt capacitance of frequency is more little, plays the short circuit effect in the electromagnetic interference circuit that spark plug produces.
