摘要： A spark plug boot keeper assembly interconnects between a spark plug boot and an internal surface of a surrounding structure which defines an elongated spark plug well. A pivoting member of the assembly is located above an annular upper shelf of the internal surface and a circumferential lower rib of the boot. When the boot is properly seated on the spark plug, the lower rib engages the upper shelf. Once engaged, the pivoting member pivots to lock the boot onto the spark plug. The pivot axis lies within an imaginary plane disposed perpendicular to a centerline of the elongated spark plug well.

摘要： A sparkplug boot keeper assembly interconnects between a heat shield and an ignition wire boot of a spark plug. A spring clip is pre-assembled internally to the heat shield which then engages a bottom portion of the spark plug after the spark plug is threaded to a head of an engine block. During assembly, as the heat shield moves axially inward over the spark plug, the pre-assembled spring clip rasps over a hexagonal portion of the spark plug and snap fits to the bottom portion. An outward facing surface of the boot is engaged to a compressed spring which in turn is engaged to an outward wall of the heat shield. Either a rotation, or an axially outward withdrawal force placed upon the heat shield, will radially expand the spring clip permitting disengagement of the heat shield and spring clip assembly from the stationary spark plug.

摘要： An engine ignition coil and wiring arrangement uses a connection position assurance device to assist in the connection of ignition wires to an ignition coil and the maintenance of the connections in engine use. The ignition coil is provided with a pair of parallel terminal posts and a mounting surface adjacent a bolt opening. Each of a pair of ignition wires has a cable portion and a connector portion. The connection position assurance device is a T-shaped element having tower portion with a bolt opening extending lengthwise therethrough and pair of connector holding portions extending in opposite directions adjacent one end of the tower portion. Each of the connector holding portions defines a central cavity for the retention of a connector portion of one of the ignition wires. Specific insertion and access openings from the cavity are also provided for insertion and access of the ignition wire connector portion. The connector position assurance device is dimensioned to locate the connector portions of both ignition wires precisely in engagement with the terminal posts of the ignition coil when the device is attached by a bolt to the ignition coil or through the ignition coil to an engine powertrain component with the mounting surfaces of the device and the ignition coil in engagement.
摘要翻译： 发动机点火线圈和配线装置使用连接位置保证装置来辅助点火线与点火线圈的连接以及发动机使用中的连接的维护。 点火线圈设有一对平行的端子柱和与螺栓孔相邻的安装表面。 一对点火线中的每一个具有电缆部分和连接器部分。 连接位置保证装置是具有塔架部分的T形元件，该塔架部分具有纵向延伸的螺栓开口，并且一对连接器保持部分沿与塔架部分的一端相邻的相反方向延伸。 每个连接器保持部分限定了用于保持点火线之一的连接器部分的中心空腔。 还提供了来自腔的特定的插入和进入开口用于点火线连接器部分的插入和接近。 连接器位置保证装置的尺寸被设计成当两个点火线的连接器部分精确地与点火线圈的端子柱接合时，将该装置通过螺栓连接到点火线圈或通过点火线圈与发动机动力系组件 装置和点火线圈的安装表面接合。
