Description
Technical field
The utility model relates to a kind of motorcycle part, the ceramic resistance type spark plug cap particularly in motorcycle engine.
Background technology
Ceramic resistance type spark plug cap is the vitals in motorcycle engine, and for connecting high-voltage line and spark plug, its quality, directly affects the startability of engine.Existing ceramic resistance type spark plug cap for motorcycle is generally made up of body, spring, conductive cap, resistance and screw etc., not enough below ubiquity:
1) conductive cap adopts interference fit to be fixed in body, and dismounting is inconvenient, and efficiency of assembling is low;
2) screw is round end structure, must assemble, could realize screw and not rotate in body after cooling under Warm status (about 150 DEG C) high temperature; Moreover, the assembling of other parts is also carry out in hot state, and assembly technology is more complicated so on the one hand, and assembly manipulation is inconvenient, and operator is easy to hand to scald; On the other hand, intrinsic residue is not easy to clean out, and easily causes product poor flow;
3) resistance one end abuts with spring, and the other end abuts with screw, and the contact performance of resistance end face and screw is bad, likely occurs not conducting phenomenon; Meanwhile, the contact-making surface of resistance and spring is little, and the reliability of spring location is poor, easily occurs crooked, causes the conduction between spring and resistance poor thus.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of ceramic resistance type spark plug cap for motorcycle being easy to assemble, conduction is good.
Technical solutions of the utility model are as follows: a kind of ceramic resistance type spark plug cap for motorcycle, body (1) is " L " shape, be made up of orthogonal first straight tube (1a) and the second straight tube (1b), the endoporus of the first straight tube (1a) communicates with the endoporus of the second straight tube (1b), its key is: in described first straight tube (1a), install the first spring (2) and conductive cap (3), one end of first spring (2) abuts with at the bottom of the hole of the first straight tube (1a) endoporus, the other end abuts with conductive cap (3), conductive cap (3) and the first straight tube (1a) threaded engagement,
In described second straight tube (1b), the second spring (4) is from inside to outside installed successively, resistance (5) and screw (6), described screw (6) is outer-hexagonal tapping screw, described resistance (5) is made up of ceramic rod (5a) and the metal cap (5b) that is set in ceramic rod (5a) two ends, the blind end of metal cap (5b) caves in towards the direction of ceramic rod (5a), be formed with groove (5c), the groove bottom wall of this groove (5c) is close to the corresponding end face of ceramic rod (5a), the inner end of described second spring (4) is vertical with the first spring (2) to offset, the outer end of the second spring (4) is stretched in the groove (5c) of resistance (5) wherein one end metal cap (5b), the metal cap (5b) of resistance (5) other end stretches in the deep gouge of screw (6) head,
Two pieces of plum blossom sheets (7) stacked together are set with in the upper position near its head of described screw (6), this plum blossom sheet (7) is placed in the cone section of screw (6) admittedly, the edge of plum blossom sheet (7) bends towards the Direction distortion that screw (6) is most advanced and sophisticated, form a circle cambered surface flange, this cambered surface flange is provided with circumferentially equally distributed external tooth (7a), and described external tooth (7a) offsets with the inwall of the second straight tube (1b).
Adopt above technical scheme, the mounting means of conductive cap changes threaded engagement into by traditional interference fit, not only easy accessibility, and efficiency of assembling is high, and can assemble at normal temperatures, the disadvantage of assembling under eliminating Warm status high temperature.
Set up the metal cap of band groove at the two ends of ceramic rod, the groove bottom wall of metal cap groove engages closely with ceramic rod, and contact area is large.The metal cap of ceramic rod wherein one end adopts groove to be connected with the second spring, to the second spring location, the second spring can be located reliably, can not occur crooked on the one hand; On the other hand, the face that the second spring is contacted with ceramic rod by metal cap is larger, and conduction property is better.The metal cap of the ceramic rod other end stretches in the deep gouge of screw head, and resistance and screws contact area are larger, and contact performance is better, can effectively eliminate not conducting phenomenon.Resistance two ends metal cap is symmetrical arranged groove, and such resistance is installed does not have directivity, loads arm faster.
Screw adopts outer-hexagonal tapping screw, utilizes the outer-hexagonal of screw head to match with the second straight tube endoporus, plays anti-rotation, rotate to avoid screw in the second straight tube; Meanwhile, above structure can be assembled at normal temperatures, and the mounting process of whole like this ceramic resistance type spark plug cap for motorcycle can carry out at normal temperatures, and assembly technology is simple on the one hand, and assembly manipulation is convenient, fast, and hand can not be scalded by operator; On the other hand, intrinsic residue is easily cleaned out, and can effectively prevent product poor flow.
It is fastening that plum blossom sheet utilizes the conical surface on screw to carry out, quick for installation, and fixing is good; The edge of plum blossom sheet has a circle cambered surface flange, and resistance when screw loads the second straight tube is little; After being seated, the external tooth on two pieces of plum blossom sheet cambered surface flange is that pawl shape and the second straight tube inwall offset, and plays location, can prevent screw from coming off out in the second straight tube.
The endoporus of described second straight tube (1b) is inner small and outside big syllogic stepped hole, at the minimal segment of the second straight tube (1b) endoporus, the second spring (4) and resistance (5) are set, the largest segment of the second straight tube (1b) endoporus arranges screw (6), the interlude of the second straight tube (1b) endoporus is interior ten two corner apertures suitable with screw (6) head, and the head of screw (6) stretches into the interlude of the second straight tube (1b) endoporus.Above structural body processing and fabricating is easy, is easy to the demoulding; The part that second straight tube endoporus matches with screw head is interior 12 corner apertures, and anti-rotation is effective on the one hand, and on the other hand, as long as all can be loaded inwardly in interior 12 corner apertures by screw head, assembling is simpler, quick.
The aperture place of described second straight tube (1b) endoporus is provided with taper flaring structure.Taper enlarging plays guiding, so that parts load in the second straight tube.
High temperature oil enamelled coating (8) is coated with it in the outside of described metal cap (5b) opening end and ceramic rod (5a) rod be positioned between two metal caps (5b).The opening end of metal cap is hidden in high temperature oil enamelled coating, and high temperature oil enamelled coating plays sealing, and steam etc. can be avoided to enter the conduction property affecting ceramic resistor in metal cap; Meanwhile, high temperature oil enamelled coating can also aesthetic appeal, makes ceramic resistor more attractive in appearance.
Beneficial effect: the utility model structure is simple, be easy to assembling, efficiency of assembling is high, can complete assembling at normal temperatures on the one hand, avoid operator and be burned, and intrinsic residue easily be cleaned out, can effectively prevent product poor flow; On the other hand, resistance and spring and screws contact area large, contact performance is better, can improve conduction property further.
