Abstract
The utility model discloses a conduction cap of a spark plug cap comprising a cylinder, wherein an introduction port is set at one end of the cylinder and a cylinder bottom is set at another end of the cylinder and a locking port is radially opened at the end of cylinder near to the introduction port and a clamp spring is set at the locking port and drop-out prevention holes are set at the end of the cylinder neat to the cylinder bottom, The drop-out prevention holes are two circular holes. The conduction cap of the spark plug cap has features of simple structure, high production efficiency, low production cost, stable production quality, reliable use, no looseness of conduction cap and stable contact with the spark plug and remarkable increased use effect.
Description
Technical field
The utility model relates to the spark plug cap of motorcycle ignition coil, more specifically relates to the conductive cap of spark plug cap.
Background technology
The conductive cap of spark plug cap is the strength member in the spark plug cap, and it is installed in the spark plug cap, is used for and being connected of spark plug.At present, the conductive cap majority of spark plug cap is the copper conductive cap, the wall of conductive cap is a cylinder type, one end of cylinder type is an introducing port, be used for and being connected of spark plug, at the bottom of the other end of cylinder type is cylinder, by on the cylinder of introducing port one end, radially have locking mouthful, a mouthful place is provided with jump ring in locking, be provided with screw thread on the cylinder outer wall of conductive cap, the internal thread on the body of screw thread and spark plug cap is connected, though the conductive cap of this spark plug is feasible with the structure that the body of spark plug cap is threaded, but exist spark plug cap production difficult, cost is higher, and conductive cap is easily loosening when vibration, waits deficiency.For this reason, in recent years the someone has invented the intrinsic spark plug cap that conductive cap is squeezed in spark plug cap, as, Granted publication day is on May 30th, 2007, Granted publication number is CN 2907004Y, the patent No. is ZL 200620110678.6, name is called " motorcycle spark plug cap ", disclosed technical scheme, this spark plug cap comprises body, resistance, spring, screw, conductive cap, reed, its conductive cap is the stainless steel cylinder, axially have straight joint on the cylinder, cylinder is squeezed in the body, radially has the locking mouth on cylinder, and a mouthful place is provided with jump ring in locking.Though this stainless conductive cap can be squeezed among the body, owing to axially have straight joint on the cylinder, make conductive cap be easy to from body, become flexible, come off, have a strong impact on result of use.For this reason, the structure of the conductive cap of the existing spark plug cap that is further improved to simplify production technology, to reduce production costs, is enhanced productivity, and improves result of use.
Summary of the invention
The purpose of this utility model: provide a kind of production efficiency height, production cost low, the quality of production is stable, the conductive cap of service-strong spark plug cap.
The technical solution of the utility model is: a kind of conductive cap of spark plug cap, comprise cylinder, one end of cylinder is an introducing port, at the bottom of the other end of cylinder is cylinder, leaning on the cylinder of introducing port one end, radially have the locking mouth, a mouthful place is provided with jump ring in locking, is provided with the slip-off preventing hole on the cylinder by an end at the bottom of the cylinder.
Described slip-off preventing hole is two circular holes.
When the conductive cap of spark plug cap of the present utility model was produced, available punch press struck out the band cylinder at the end with sheet metal, and processing locks mouth, slip-off preventing hole on cylinder thereafter, at locking mouthful place's installation jump ring.When the conductive cap of spark plug cap uses, when the body of taking advantage of the spark plug cap of injection mo(u)lding is warmware, earlier relevant part is contained in the body, then this conductive cap is pressed in the corresponding aperture in the spark plug cap, when treating the body cooling of spark plug cap, the phenolic resins of the body of spark plug cap shrinks the back and embeds in the slip-off preventing hole of conductive cap, and conductive cap firmly is embedded in the body of spark plug cap.
The beneficial effects of the utility model: the conductive cap of spark plug cap of the present utility model, simple in structure, production efficiency height, production cost are low, and the quality of production is stable, uses reliably, and conductive cap is loosening, and is firm with contacting of spark plug, significantly improved result of use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2: a kind of conductive cap of spark plug cap, comprise cylinder 4, one end of cylinder 4 is an introducing port 1, the other end of cylinder 4 is at the bottom of the cylinder 6, leaning on the cylinder 4 of introducing port 1 one ends, radially have locking mouth 2, mouthful 2 places are provided with jump ring 3 in locking, are provided with slip-off preventing hole 5 on the cylinder 4 by 6 one ends at the bottom of the cylinder.Described slip-off preventing hole 5 is two circular holes.
Claims (2)
1, a kind of conductive cap of spark plug cap, comprise cylinder (4), one end of cylinder (4) is introducing port (1), the other end of cylinder (4) is (6) at the bottom of the cylinder, leaning on the cylinder (4) of introducing port (1) one end, radially have locking mouthful (2), locate to be provided with jump ring (3), it is characterized in that: on cylinder (4), be provided with slip-off preventing hole (5) by (6) one ends at the bottom of the cylinder in locking mouthful (2).
