Description
Technical field
The present invention relates to a kind of engine components, particularly to the ceramic resistance type spark plug on general purpose engine
Cap.
Background technology
Ceramic resistance type spark plug cap is the vitals on general purpose engine, is used for connecting high-voltage line and spark
Plug, its quality, directly affect the startability of logical machine.Chinese patent ZL 200820098167.6 in
The spark plug cap that on March 18th, 2009 discloses a kind of general purpose engine, installs supervisor in the supervisor of body
Spring, jump ring and conductive cap, install arm spring, resistance and screw in the arm of body, above structure
Deficiency is:
1) conductive cap uses interference fit to be fixed in the supervisor of body, and dismounting inconvenience, efficiency of assembling is low；
2) screw is round end structure, it is necessary to assemble under Warm status (about 150 DEG C) high temperature, after cooling
Screw can be realized do not rotate in arm；Moreover, the assembling of other parts is also to carry out in hot state,
So on the one hand, assembly technology is more complicated, and assembly manipulation is inconvenient, and operator is easy to scald hands；Separately
On the one hand, intrinsic residue is not easy to clean out, and easily causes product poor flow；
3) resistance one end abuts with arm spring, and the other end abuts with screw, and resistance end face contacts with screw
Performance is bad, it is possible to occur being not turned on phenomenon；Meanwhile, resistance is little with the contact surface of arm spring, arm
The reliability of spring location is poor, is susceptible to crooked, thus causes the conducting between arm spring and resistance
Property is poor.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide one and is prone to
Assembling, the ceramic resistance type sparking plug cap of general engine that conduction is good.
Technical solution of the present invention is as follows: a kind of ceramic resistance type sparking plug cap of general engine, and body (1) is main
The oblique one of pipe shaft of pipe (1a) extends, and forms arm (1b), and described supervisor (1a) is built with supervisor's bullet
Spring (2) and conductive cap (3), one end of supervisor's spring (2) abuts with the step surface in supervisor (1a),
The other end abuts with conductive cap (3), installation arm spring (4) the most successively in described arm (1b),
Resistance (5) and screw (6), it it is critical only that: described conductive cap (3) and supervisor's (1a) threaded engagement,
Described screw (6) is outer-hexagonal tapping screw, and described resistance (5) is by ceramic rod (5a) and is set in pottery
Metal cap (5b) composition at porcelain rod (5a) two ends, the blind end of metal cap (5b) is towards ceramic rod (5a)
Direction depression, be formed with groove (5c), the groove bottom wall of this groove (5c) is corresponding with ceramic rod (5a)
End face is close to, and resistance (5) wherein one end metal cap (5b) is stretched in the end of described arm spring (4)
In groove (5c), the metal cap (5b) of resistance (5) other end stretches in the deep gouge of screw (6) head；
It is installed with Flos Mume sheet (7), the limit of this Flos Mume sheet (7) in the upper position near its head of described screw (6)
Edge bends towards the Direction distortion that screw (6) is most advanced and sophisticated, forms a circle cambered surface flange, and this cambered surface flange is provided with
The most equally distributed external tooth (7a).
Using above technical scheme, the mounting means of conductive cap is changed into threaded engagement by traditional interference fit,
Not only easy accessibility, efficiency of assembling is high, and can assemble at normal temperatures, eliminates Warm status high temperature
The disadvantage of lower assembling.
Set up metal cap with groove at the two ends of ceramic rod, the groove bottom wall of metal cap groove engages with ceramic rod
Closely, contact area is big.The metal cap of ceramic rod wherein one end uses groove to be connected with arm spring, a side
Arm spring can be positioned by face, makes arm spring location reliable, will not occur crooked；On the other hand, prop up
The face that pipe spring is contacted with ceramic rod by metal cap is bigger, and conduction property is better.The ceramic rod other end
Metal cap stretches in the deep gouge of screw head, and resistance and screw contact area are bigger, and contact performance is more preferable, energy
Effectively eliminate and be not turned on phenomenon.Resistance two ends metal cap is symmetrical arranged groove, and such resistance is installed does not has direction
Property, load arm faster.
Screw uses outer-hexagonal tapping screw, utilizes the outer-hexagonal of screw head to match with a pipe orifice, rises
The effect of anti-rotation, to avoid screw to rotate in arm；Meanwhile, above structure can fill at normal temperatures
Joining, the mounting process of the most whole engine spark plug cap can be carried out at normal temperatures, on the one hand assembler
Skill is simple, and assembly manipulation is convenient, fast, and hands will not be scalded by operator；On the other hand, intrinsic
Residue is easily cleaned out, and can effectively prevent product poor flow.
The edge of Flos Mume sheet has a circle cambered surface flange, and resistance during screw loading arm is little；After assembling puts in place,
External tooth on cambered surface flange is that pawl shape offsets with branch pipe wall, plays the effect of location, and screw can be prevented from propping up
Pipe is interior backing out.
The endoporus of described arm (1b) is inner small and outside big syllogic stepped hole, at arm (1b) endoporus
Minimal segment arranges arm spring (4) and resistance (5), and the largest segment of arm (1b) endoporus arranges screw (6),
The interlude of arm (1b) endoporus is interior ten two corner apertures suitable with screw (6) head, screw (6)
Head stretch into the interlude of arm (1b) endoporus.Above structural body processing and fabricating is easy, it is easy to the demoulding；
The part that pipe orifice matches with screw head is interior 12 corner apertures, and on the one hand anti-rotation is effective, the opposing party
Face, as long as the most all can be loaded by screw head in interior 12 corner apertures, assembling is simpler, quick.
It is positioned at two metal caps (5b) in the outside of described metal cap (5b) opening end and ceramic rod (5a)
Between rod be coated with high temperature oil enamelled coating (8).The opening end of metal cap is hidden in high temperature oil enamelled coating,
High temperature oil enamelled coating plays the effect of sealing, it is possible to avoid steam etc. to affect leading of ceramic resistor in entering metal cap
General character energy；Meanwhile, high temperature oil enamelled coating can also aesthetic appeal, make ceramic resistor more attractive.
Described metal cap (5b) is stamped to form by the chromium plate that 0.27-0.33mm is thick, chromium utilized above good
Ductility, not only processing technique is simple, and production efficiency is high, and the structural strength of metal cap is good, is difficult to send out
The shape that changes or damage.
Beneficial effect: one aspect of the present invention can complete assembling at normal temperatures, it is to avoid operator is burned,
And intrinsic residue is easily cleaned out, can effectively prevent product poor flow；On the other hand, electricity
Resistance is big with arm spring and screw contact area, and contact performance is more preferable, it is possible to improve conduction property further.
