Abstract: A plug connector has a U-shaped snap-on clip with a web, which incorporates a contact lug. The web is seated in a slot of the casing. A contact is situated at the end of the U-shaped snap-on clip, between its arms. An opening for inserting a contact pin is situated in the top side of the housing. This contact pin spreads the arms of the U-shaped snap-on clip, so that they detach from the contact. This plug connector, which is especially suited for use in a cordless radiotelephone, is distinguished by a small structural size, low production costs, a small number of components, high contact reliability, and an especially low juncture resistance.

Abstract: A connector assembly for protecting against cable discharge with respect to static charges that may accumulate on cables and other conductors. The connector assembly comprises a modular plug that mates with a modular jack. The modular jack comprises a plurality of resilient contacts that connect to rigid contacts on the modular plug when the plug and jack mate. The modular jack also supports a grounding conductor such that the jack contacts connect to ground when the jack and plug are unmated. As the plug and jack begin to mate, the jack contacts connect a ground potential to the plug contacts, thereby discharging to ground any static charge that may be stored on the cable. As the jack and plug continue to mate, the plug contacts disconnect the jack contacts from the grounding conductor. When the jack fully mates with the plug, cable conductors connect to an electronic circuit via the jack and plug contacts.

Abstract: A lamp having a light bulb connected to a base insertable into a light socket in such a way that insertion breaks an electrical circuit between two spring terminals inside the socket and reestablishes it through the lead wires on the light bulb. The light bulb has a filament and two lean wires connected to the filaments. The filaments extend from the bottom of the base and are bent outwardly and upwardly around the base. The bulb with its base are insertable into the light socket. Wires from a source of electricity enter the socket and form electrical terminals, one on either side of the socket. Two spring terminals within the socket are biased toward each other and will conduct when supplied with an electrical potential unless separated. A protrusion on the base of the light bulb separates the spring terminals. Thus, in a light string where the lights are electrically in series, removal of a light bulb of the present invention will not cause the string to go out.

A relatively thick short-circuit canceling member of a male housing is inserted from the front opening into the chamber, whereupon resilient contact members of the short-circuiting terminal bend downwards. The free ends of the terminal enter the recessed opening. While the short-circuiting terminal is provided with a greater bending stroke, the chamber can be kept low in height due to the recessed opening. Accordingly, the male housing can be kept small, and thus miniaturized.
