Abstract: A terminal formed by bending from a single metal piece for use in a bulb socket having a bulb insertion opening for accommodating a bulb, where the terminal is used for connecting with a base electrode formed in the outer perimeter of the bulb includes a contact element. The contact element is formed by stamping the metal piece to have a contact portion and a spring portion for resiliently hold the contact portion in contact with the base electrode. The spring portion is located on a position away from the base electrode when the bulb is inserted in the bulb insertion opening. Therefore, the spring porion of the contact element is kept from deterioration of spring characteristics caused by the heat from the bulb.

Abstract: A cathode terminal, to be mounted on a bulb socket, comprising a first connection strip which is elastically connected with the cathode of a mouth piece of a bulb; and a second connection strip to be connected with a connector. The cathode terminal has a locking portion formed at the leading end thereof by bending said cathode terminal so as to cover the upper end of said opening of said terminal inserting groove. Therefore, the pin of the bulb cannot be inserted into the cathode terminal inserting groove.

Abstract: A coupling construction for coupling a high-voltage terminal of an ignition coil for use in an internal combustion engine and an electric conductor with each other. The high-voltage terminal is inserted into the electric conductor. An engaging ring engages the peripheral surface of the electric conductor. An engaging convex portion of the engaging ring projecting inward toward the high-voltage terminal through a through-hole engages the engaging concave portion of the high-voltage terminal due to the contraction of the engaging ring. After the high-voltage terminal and the electric conductor are coupled with each other, a moving sleeve engages the peripheral surface of the engaging ring, thereby preventing the diameter of the engaging convex portion of the engaging ring from expansionarily increasing more than a predetermined length.

Abstract: A cathode terminal, to be mounted on a bulb socket, comprising a first connection strip which is elastically connected with the cathode of a mouth piece of a bulb; and a second connection strip to be connected with a connector. The cathode terminal has a locking portion formed at the leading end thereof by bending said cathode terminal so as to cover the upper end of said opening of said terminal inserting groove. Therefore, the pin of the bulb cannot be inserted into the cathode terminal inserting groove.

Abstract: A bulb socket including a center electrode contact and a side electrode contact, each having elastic contact members at the forward end thereof, and a socket body wherein a bulb insertion portion and an electrode contact housing are formed having an inclination angle. The electrode contact housing includes a center electrode contact housing chamber and a side electrode contact housing chamber inclined relative to the bulb insertion portion. Each contact housing chamber has flexible retaining members retaining engaging portions of corresponding electrode contacts. Thus, the ease of assembling the bulb socket can be improved.
