摘要： The plug connection comprises an elastomeric shroud having a plug-receiving portion through which is connected a spark plug comprising an hexagonal handling nut. A metal shield, comprising a top cover portion and two side-shield portions, covers the elastomeric shroud. When mounted, the side-shield portions surround the plug-receiving portions and form joint seam zones, each having a bottom end portion and a top portion. The bottom end portion of one seam zone includes an opening and the bottom end portion of the other seam zone includes a corresponding tab. The side-shield portions further comprise flanges. When the plug connection is connected to the spark plug, the flanges fit onto the hexagonal handling nut and the opening and tab are loosely fitted, so that the joint seam zones can be spaced apart. Preferably, the top portion contains protrusions provided on the side of the side-shield portions and a corresponding recess provided on the side of the top shield, these protrusions and recess fit together when the shield is mounted.
摘要翻译：插头连接件包括具有插头接收部分的弹性体护罩，通过该插头接收部分连接有包括六角形处理螺母的火花塞。包括顶盖部分和两个侧面遮蔽部分的金属屏蔽罩覆盖弹性体护罩。当安装时，侧屏蔽部分围绕插头接收部分并形成各自具有底端部分和顶部部分的接缝区域。一个接缝区域的底端部分包括开口，另一个接缝区域的底端部分包括相应的接头。侧屏蔽部分还包括凸缘。当插头连接件连接到火花塞时，凸缘装配在六角形处理螺母上，并且开口和突片松动地安装，使得接缝区域可以间隔开。优选地，顶部包含设置在侧屏蔽部分侧面的突起和设置在顶部屏蔽侧上的相应凹部，当安装屏蔽时，这些突起和凹陷配合在一起。

摘要： A plug boot contains an ignition cable which is fitted with the stud terminal of a spark plug extending from an engine cylinder block. This plug boot is covered with a heat shield, and further with an auxiliary heat shield. The cylinder-side end portion of the auxiliary heat shield is fixed between the spark plug and the cylinder block. The cable-side end portion of the auxiliary heat shield is provided with a lid unit. This lid unit includes a fixing retaining member and a pressing portion. The fixing retaining member fits the lid unit to the auxiliary heat shield, while the pressing portion exerts downward forces on the plug boot. By the combination of fitting forces and downward forces, the ignition cable and the spark plug are reliably connected.

摘要： There is provided a structure of a connecting part between an ignition plug and an ignition cable which makes it possible to make a connection between a connection terminal on the ignition cable and an end terminal on the ignition plug with more reliable security. A first elastomeric bushing is fitted into an upper end side of a plug tube formed of a ceramic material, and a second elastomeric bushing is fitted into the lower end of the plug tube. The portion of the ignition cable K near the high voltage terminal T is held by the first bushing so that the high voltage terminal is held at a predetermined position in the plug tube. Thus, when the second bushing is fitted over an insulator of the ignition plug, the high voltage terminal and the end terminal are secured in a positive electrically connected condition within the plug tube.

摘要： There is provided a high voltage terminal for an ignition cable with which it is possible to easily mount and more accurately position a spring member which is accommodated in the terminal to provide a more reliable electrical connection with an ignition plug having a generally columnar terminal, such as an end terminal. A spring member is provided at its opposite ends with portions having a larger diameter than the diameter of the intermediate portion in the longitudinal direction thereof. When the spring member is disposed within a terminal of generally tubular shape, a C-ring member having a pair of projections is clipped onto the terminal to extend within apertures in the terminal. Each projection of the C-ring member projects into the terminal, so that the spring member is held within the terminal under the condition where the large diameter portion at one end of the spring member is fixed in position between a contact piece of the terminal and the projections of the C-ring member which project into the terminal.
摘要翻译：提供了一种用于点火电缆的高压端子，通过该高压端子可以容易地安装并且更精确地定位容纳在端子中的弹簧构件，以提供与具有大致柱形端子的火花塞的更可靠的电连接，作为终端。弹簧构件的相对端设有直径大于中间部分在其纵向方向上的直径的部分。当弹簧构件设置在大体管状的端子内时，具有一对突起的C形环构件被夹在端子上以在端子中的孔内延伸。 C形环构件的每个突出部突出到端子中，使得弹簧构件在弹簧构件的一端处的大直径部分固定在端子的接触件与接触件的接触件之间的位置的状态下保持在端子内投入到终端的C形环构件的突出部分。
