JPS5943979A - Connector for ignition coil - Google Patents

Abstract

PURPOSE:To improve both the reliability of electric connection and the workability of a connector, by forming the connector in such a manner that circuit elements are electrically connected and molded with resin to a conductive terminal member electrically connected to an ignition coil. CONSTITUTION:A conductive terminal member 23 is constituted such that connection pin parts 23a are formed with the terminal end part in a fork shape while an engaged hole 23b engaging each stud 21a, 21b of an ignition coil is equipped in the point end and a terminal part 23d is formed. The terminal member is integrally formed by press punching with the electric connection of a capacitor 24 and a resistor 25 to the terminal end part, and integrally molded by resin with the exposure of the connection pin parts 23a. In this way, any possibility of harness to be entangled is not provided because the harness is not necessary for connection to each unit, while any improper contact is not caused because a coupling connector is used.

In case the harness is tangled, or the phase f is the case, the wiring wire 1 is connected to the cow. Because they are connected by connectors, the reliability of the electrical connections between each connector is reduced, and because there are many connection points, there are problems such as poor production, etc. (Part 1) This invention This J was considered 3111 problems.
Therefore, in order to simplify the wiring around the ignition terminal, it is necessary to make the wiring around the ignition terminal simple. .Electrical elements such as resistors and resistors for other circuits are electrically connected to the second conductive 1'1 termination member and formed as a connector using resin mold 17.'' Simple solution of the problem 1' is equivalent to [1]. Hereinafter, embodiments of the present invention will be explained in detail based on the drawings. 1 shows a first embodiment of the present invention, 20 indicates a conventionally known ignition coil, and studs 21a on the end side of the coil 20 and studs 21a on the same terminal side are installed on both sides of the end surface of the coil 20. 2
