Description
Technical field
The utility model relates to a kind of engine components, particularly a kind of conductive cap for universal machine spark plug cap.
Background technology
Spark plug cap is the vitals on universal machine, for connecting high-voltage line and spark plug, and its quality, the directly startability of the logical machine of impact.Traditional spark plug cap is by body and be arranged on the compositions such as intrinsic conductive cap, resistance, spring, reed, screw, the conductive cap used adopts interference fit to be fixed in the supervisor of body, quality of fit is high on the one hand, high to the requirement on machining accuracy of part, can production cost be increased, on the other hand, must hot pressing be at high temperature adopted to assemble, assembly manipulation is inconvenient, and efficiency of assembling is lower, and easily causes the hand of operating personnel to scald.
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 logical machine conductive cap being easy to assemble.
Technical solutions of the utility model are as follows: a kind of logical machine conductive cap, there is conductive cap body (1), it is characterized in that: the cylinder that described conductive cap body (1) is the uncovered lower end closed in upper end, screw thread (2) is provided with at the outer wall of conductive cap body (1) epimere, the outer wall of described conductive cap body (1) hypomere is arranged side by side upper and lower two draw-in grooves (3), described draw-in groove (3) is annular groove, the bottom land of each draw-in groove (3) is equipped with an opening (4), draw-in groove (3) is communicated with by the inside of this opening (4) with conductive cap body (1).
Adopt above technical scheme, conductive cap moulding is simple, and processing and fabricating is easy, and cost is low; Conductive cap passes through screw thread and the spark plug cap body threaded engagement of its epimere, and not only required precision is low, easy accessibility, and efficiency of assembling is high, and can assemble at normal temperatures, the disadvantage of assembling under eliminating Warm status high temperature.Annular groove on conductive cap body lower end outer wall for installing jump ring, and can make the straight section of jump ring embed in the opening of card round bottom land, thus ensure that the fastness that jump ring is installed.Conductive cap is set with two jump rings side by side, spark plug cap can be strengthened and be connected later pulling capacity with spark plug, thus effectively prevent spark plug cap from occurring to loosen or come off.
Be provided with two circumferentially equally distributed breach (5) in the lower surface of described conductive cap body (1), two breach form flat recesses, stretch into for instruments such as bottle openers, make to turn time conductive cap carries out dismounting more convenient, laborsaving.
As preferably, the open-mouth of described conductive cap body (1) lower end is tubaeform.
By taper seat transition between the end face of described conductive cap body (1) and periphery, play guiding like this during assembling and reduce friction, making assembling easier; Be provided with location notch (6) at the middle part of conductive cap body (1) end face, this location notch (6) is up big and down small taper shape, and location notch is used for spring location, make spring fitting more reliable, and it is crooked to prevent spring from occurring.
Described opening (4) is circular arc, and extends along described draw-in groove (3), above opening (4) be positioned at below directly over an opening (4).Opening is strip, is not only easy to processing and fabricating, and the contact area of access section is large, can strengthen the fixing that jump ring clamps.
In order to ensure conductivity, make processing and fabricating easier, described conductive cap body (1) is passed through machining by copper bar.
Beneficial effect: the utility model design is ingenious, structure simple, be easy to processing, production cost is low; load the simple process of spark plug cap body; efficiency of assembling is high; guarantee spark plug be connected with spark plug cap firm while; assembling can be completed at normal temperatures, avoid operator and be burned.
