ABSTRACT:
TECHNICAL FIELD
The present invention relates to a connecting structure for an electrical bulb socket and an electric wire.
BACKGROUND OF THE INVENTION
A rear combination lamp of an automobile typically has a plate-shaped body, a plurality of bulb sockets attached to the body, and electric wires connected to the bulb sockets and distributed on the body. A prior connecting means for the bulb sockets and the electric wires, as described in JP-9-231814, has connecting terminals attached to the body, and electric wires attached to the connecting terminals by pressure welding or other means. Contact members of the bulb socket make contact with the connecting terminals when the bulb sockets are attached to the body.
The conventional connecting structure requires connecting terminals between the electric wires and the bulb sockets. As a result, the number of components is large, and several attachment processes must be performed.
The present invention has been developed after taking the above problem into consideration, and aims to provide a connecting structure with fewer components.
SUMMARY OF THE INVENTION
According to the invention there is provided an electrical connecting structure comprising a body, an insulated electric wire for said body, and a bulb socket for attachment to said body and having an electrical contact, a portion of the insulation of said wire being absent, and said portion being adapted for direct contact with said electrical contact on attachment of said socket to said body. The main advantage of the invention is that intermediate terminal structure is avoided; cost is thereby reduced and furthermore the invention permits miniaturisation.
Preferably direct contact is made in the direction of attachment of the bulb socket, typically by insertion of the socket through an aperture in the body.
Preferably direct contact is made in the direction of attachment of the bulb socket, typically by insertion of the socket through an aperture in the body.
The non-insulated portion is preferably guided, for example by a channel, or being wound around a projection.
Snap-fitting means may be provided to grip the wire, preferably by indenting an insulated portion thereof, for example an insulated portion on both sides of the non-insulated portion.
