Abstract: A lamp holder has a contact spring which, instead of being bent into a U-shape and having its barb on the bracing shank opposite the retaining shank, has a bracing barb or lug bent out of the retaining shank itself and engageable as an indexing member behind a projection formed on the lamp housing.

Abstract: The present invention proposes a modified lamp series. The lamp series is a power cable with a plurality of bulb sets installed thereon. Each bulb set comprises a bulb seat, a fixing outer lid, and a bearing soft core. An accommodation groove is disposed in the bulb seal. An outer thread is formed on the upper periphery of the bulb seat. An inner thread is formed in the fixing outer lid. A retaining ring is installed on the top of the fixing outer lid. A bulb base of the light bulb penetrates an opening at the center of the retaining ring. The inner thread of the fixing outer lid can be matched exactly with the outer thread of the bulb seat such that the fixing outer lid can be screwed firmly on the bulb seat. The bearing soft core can be lapped exactly in the accommodation groove. Two opposite holes are disposed at proper positions of the bottom of the bearing soft core. The bulb base of the light bulb penetrates the opening of the fixing outer lib and is placed in the bearing soft core.

Abstract: A plastic covering 32 of an electric wire 30 is removed, exposing a core wire 31, this core wire 31 being attached to core wire receiving members 13 of a lamp body 10. Attaching a bulb socket 20 to the lamp body 10 causes the core wire to be resiliently held between contact members 24D of the bulb socket 20 and the core wire receiving members 13, thereby connecting the bulb socket 20 and the electric wire 30. The core wire 31 makes direct contact with the contact members 24D, and therefore connecting terminals are not required between the bulb socket 20 and the electric wire 30, the number of components is thus decreased.

Abstract: The present invention provides an electrical connector which is connected to wires extending from a circuit device, and which makes it possible to realize high contact reliability with mating members, and a method of assembling and connecting the electrical connector with circuit devices. Electrical wires are terminated at one end to male first terminals, the opposite ends of the wires are connected to a circuit device, and the lead out portions of the wires from the circuit device are subjected to a potting treatment. Afterward, the first terminals are accommodated inside the first housing member. The first terminals are placed in positions so as to be engaged with second terminals that have been accommodated inside the first housing member before hand. A second housing member is latched onto the first housing member and provides terminal support for the first terminals and strain relief for the electrical wires.

Abstract: A lamp socket for multipin lamps with spring-biased contacts for contacting the contact pins of a lamp, and a housing which in the final assembly state at least partially surrounds the lamp base of the lamp. The housing is composed of an upper housing part which supports a device for aligning and securing the lamp, and a bottom hosing part which supports at least indirectly receiving means for the contacts. The spring-biased contacts provided for contacting the various contact pins are arranged in individual electrically insulating and housing-like contact cages which are moveable independently of each other.

Abstract: A light bulb holder structure in which there is no need for connection terminals. The holder is especially suitable for LED type light bulbs. It primarily comprises a coupling element seated therein. Electrical wire's bare conductive ends are disposed on two sides of the coupling element to get in touch with the leads of a light emitted diode that is seated on the top of the holder with leads extending into two vertical openings of the coupling element. The holder according to the invention can provide excellent electrical contacts and sturdy combination between light emitted diodes and electrical wires.
