Abstract
The spark plug 11 with which the connector 10 is used has a terminal 12 for receiving an electrical connector (not shown) of the ignition system of an associated internal combustion engine when the plug is releasably mounted in the engine. The connector 10 comprises a tubular insulating body 14 having a lower opening which is releasably engageable exteriorly of the spark plug terminal 12 and a terminal 15 exterior of the insulating body for receiving the electrical connector. The insulating body 14 limits movement of the exterior terminal 15 toward the spark plug terminal 12, and the exterior terminal has a sparking surface, interior of the insulating body which surface, when the insulating body prevents further movement of the exterior terminal toward the spark plug terminal, is spaced from the latter to leave a series gap 18 between the surface and the spark plug terminal. <IMAGE>
Description
SPECIFICATION
Spark plug connector
This invention relates to a connector used with a spark plug releasably mounted in an associated internal combustion engine. The spark plug has a firing gap across which ignition occurs when the applied voltage reaches a specific level. The spark plug also has a terminal for receiving an electrical connector of the ignition system of the associated engine. Although the ignition system provides sufficient voltage to cause the spark required to operate the engine, it frequently occurs that because of electrical leakage, sometimes attributable to deposits on the spark plugs, the ignition system fails to produce sufficient voltage to operate an engine on a new automobile when it arrives at its destination.
The present invention is based on a connector for a spark plug having a terminal for receiving an electrical connector of the ignition system of an associated internal combustion engine when the plug is releasably mounted in the engine. The connector comprises a tubular insulator body having a lower opening which matches and is releasably engageable exteriorly of the spark plug terminal and a terminal exterior of the insulating body for receiving the electrical connector. The insulator body is effective to limit movement of the exterior terminal toward the terminal of the spark plug.The exterior terminal has a sparking surface interior of the insulating body which surface, when the insulating body prevents further movement of the exterior terminal toward the spark plug terminal, is spaced from the spark plug terminal to leave a series gap between the electrical connector and the spark plug terminal.
Such a series gap between the interior terminal of the connector and the spark plug terminal isolates the spark plug firing gap from the ignition energy source until a sufficiently high voltage level is reached to cause the auxiliary series gap to break down, whereupon a high voltage is applied almost instantaneously, rather than a comparatively slowly increasing voltage to the spark plug firing gap. It has been found that the use of a connector according to the invention usually enables the firing of plugs having fouling of the type that sometimes occurs after low temperature operation; without the connectors such engines often will not start.Because the connector can be used in conjunction with the existing electrical connector and spark plug terminal, it can be installed easily and quickly in the ignition system of the internal combustion engine to solve what is often an urgent problem.
It is an object of the present invention to provide, for use with a spark plug, a connector that creates an auxiliary gap ahead of the spark plug firing gap.
It is a further object to provide, for use with a spark plug, a connector that can be easily installed
in the ignition system for an internal combustion
engine.
The accompanying drawing is a view in vertical
elevation, with parts broken away, to show details
of construction, of a spark plug with a partially schematic view of a connector in accordance with the invention attached thereto.
Referring to the drawing, a connector 10 is
shown engaging a spark plug 11 having terminal 12 for receiving an electrical connector (not shown) and a firing gap 1 3 for igniting an air-fuel mixture when the spark plug is mounted in an associated internal combustion engine. The connector 10 comprises a tubular insulating body
14 having a lower opening with an inner diameter which matches and is releasably engageable with the outer diameter of the spark plug terminal 12, an exterior terminal 1 5 for receiving the electrical connector (not shown), and an interior terminal 1 6 structurally integral with the exterior terminal 1 5.
The tubular insulating body 14 has a central portion 17 of reduced inner diameter which engages the spark plug terminal 12 to prevent longitudinal movement thereof beyond the position shown in which the interior terminal 16 is positioned in spark gap relationship with the spark plug terminal 12.
The length of the central reduced diameter portion 17 determines the length of an auxiliary, series gap 1 8 between the interior terminal 1 6 and the spark plug terminal 12, and isolates the spark plug firing gap 13 from the ignition energy source until a sufficiently high voltage level is attained. When that level is reached, the auxiliary gap 18 breaks down and allows current to flow, thus applying a high instantaneous voltage rather than a comparatively slowly increasing voltage to the spark plug firing gap 13.
1. A connector for a spark plug having a terminal for receiving an electrical connector of the ignition system of an associated internal combustion engine when the plug is releasably mounted in the engine, said connector comprising a tubular insulating body having a lower opening which matches and is releasably engageable exteriorly of the spark plug terminal, and a terminal exterior of said insulating body for receiving the electrical connector, said insulating body being effective to limit movement of said exterior terminal toward the terminal of the spark plug, and said exterior terminal having a sparking surface interior of said insulating body which surface, when the insulating body prevents further movement of said exterior terminal toward the spark plug terminal, is spaced from the spark plug terminal to leave a series gap between the electrical connector and the spark plug terminal.
2. A connector for a spark plug substantiaily as described with reference to, and as illustrated in, the accompanying drawing.
