Abstract
The invention discloses a ceramic resistor of a spark plug cap. The ceramic resistor comprises a ceramic rod (1), wherein metal caps (2) are sleeved at two ends of the ceramic rod (1); the sealed end of each metal cap (2) is concave towards the direction of the ceramic rod (1), so as form a groove (3); the bottom wall of the groove (3) is tightly attached to the corresponding end surface of the ceramic rod (1); the outer side of the opening end of each metal cap (2) and the rod body of the ceramic rod (1), between the two metal caps (2), are coated with a high temperature paint coating (4). According to the ceramic resistor, the metal caps are additionally arranged at two ends of the ceramic rod; the conduction performance of the ceramic resistor can be effectively improved; the ceramic resistor has the characteristics of ingenious design, simple structure, easiness in modification and low modification cost.
Description
Technical field
The present invention relates to a kind of spark plug cap parts, the ceramic resistor particularly on spark plug cap.
Background technology
Spark plug cap is the vitals on automobile, motorcycle and logical machine, and for connecting high-voltage line and spark plug, its quality, directly affects the startability of automobile, motorcycle or logical machine.Ceramic resistor is arranged in spark plug cap, and its one end abuts with spring, and the other end abuts with metalwork.Existing ceramic resistor is the ceramic rod structure carrying resistance, and existing deficiency is:
1) contact performance of ceramic resistor end face and metalwork is bad, likely occurs not conducting phenomenon.
2) contact-making surface of ceramic resistor and spring is little, and the reliability of spring location is poor, easily occurs crooked, causes the conduction between spring and ceramic resistor poor thus.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide the good spark plug cap ceramic resistor of a kind of conduction.
Technical solution of the present invention is as follows: a kind of spark plug cap ceramic resistor, comprise ceramic rod (1), metal cap (2) is all set with at the two ends of described ceramic rod (1), the blind end of this metal cap (2) caves in towards the direction of ceramic rod (1), be formed with groove (3), the groove bottom wall of this groove (3) is close to the corresponding end face of ceramic rod (1), is coated with high temperature oil enamelled coating (4) with it in the outside of described metal cap (2) opening end and ceramic rod (1) rod be positioned between two metal caps (2).
The present invention sets 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 spring, can locate spring on the one hand, make spring location reliably, can not occur crooked; On the other hand, the face that 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 adopts groove to be connected with metalwork, and contact performance is better, can effectively eliminate not conducting phenomenon.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.
Described metal cap (2) is stamped to form by the chromium plate that 0.27-0.33mm is thick, more than utilizes the good ductility of chromium, and not only processing technology is simple, and production efficiency is high, and the structural strength of metal cap is good, not easily deforms or damages.
Conveniently processing and fabricating, improves packaging efficiency, and it is firm that metal cap is installed, and described metal cap (2) is assembled on ceramic rod (1) by press-fiting.
Beneficial effect: the present invention sets up metal cap by the two ends at ceramic rod, effectively can improve the conduction property of ceramic resistor, has the features such as design is ingenious, structure simple, transformation is easy, improvement cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, the present invention has ceramic rod 1, and this ceramic rod 1 is for carrying the column structure of resistance.Be equipped with metal cap 2 at the two ends of ceramic rod 1, metal cap 2 is preferably stamped to form by the chromium plate that 0.27-0.33mm is thick, and is assembled on ceramic rod 1 by press-fiting.The blind end of metal cap 2 caves in towards the direction of ceramic rod 1, and be formed with groove 3, the groove bottom wall of this groove 3 is close to the corresponding end face of ceramic rod 1.In the outside of metal cap 2 opening end and ceramic rod 1, the rod between two metal caps 2 is coated with high temperature oil enamelled coating 4 with it, and the opening end of metal cap 2 is hidden in high temperature oil enamelled coating 4.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection range of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
Claims (3)
1. a spark plug cap ceramic resistor, comprise ceramic rod (1), it is characterized in that: be all set with metal cap (2) at the two ends of described ceramic rod (1), the blind end of this metal cap (2) caves in towards the direction of ceramic rod (1), be formed with groove (3), the groove bottom wall of this groove (3) is close to the corresponding end face of ceramic rod (1), is coated with high temperature oil enamelled coating (4) with it in the outside of described metal cap (2) opening end and ceramic rod (1) rod be positioned between two metal caps (2).
