Problems solved by technology

Among them, 2 contacts are used for grounding (negative pole) and can be shared, but even so, at least 3 contacts and 3 wires are required. Since the lamp holder body is assembled in the above-mentioned order for these 3 contacts, Therefore, the aforementioned problems are more obvious

Embodiment Construction

[0022] Next, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a perspective view of an embodiment of the present invention, and Fig. 2 is a partially exploded perspective view seen from the rear thereof. image 3 is the top view of the lamp holder, Figure 4 is along image 3 Sectional view of line AA. The lamp holder 10 has a substantially cylindrical lamp holder body 11, which is formed by resin molding. The lower rear end portion constitutes a contact penetration cylinder 13 . In addition, the socket main body 11 in the boundary region between the bulb supporting portion 12 and the contact penetration tube 13 is formed in a cylindrical shape, and constitutes a bayonet portion 14 for mounting the socket 10 on a lamp. In the lamp socket body 11, in the region from the bulb supporting portion 12 to the contact member penetration cylinder 13, a plurality of contact pieces processed from metal sheets such as copper plates...

Abstract

A bulb socket has a socket body having a bulb supporting part for supporting a wedge base bulb, and plural contacts incorporated in the socket body and electrically abutted on the electrodes of the wedge base bulb, plural contact insertion cylinders are formed on the socket body. A cable is connected to each of the contacts, and individually independent sealing bushing is integrally assembled with it. When the respective contacts each are inserted into the socket body through the contact insertion cylinder, and the contacts are supported in the bulb supporting part, the sealing bushings are pressed in the contact insertion cylinder at the same time, and each space between the able and the contact insertion cylinder is sealed. The present invention is capable of reducing assembly hours, preventing the cable from disconnection and facilitating the assembly of the bulb socket.

Description

technical field [0001] The present invention relates to a lamp holder for installing a bulb as a light source of a lamp on a lamp housing, in particular to a lamp holder for a wedge-shaped base bulb without a cap. Background technique [0002] Lamps for automobiles use wedge-shaped base bulbs without bases as light bulbs. In this wedge-shaped base bulb, a part of a bulb part made of glass is used as a base part, and electrodes electrically connected to a filament housed in the bulb part are arranged on the base part. Therefore, in the wedge-shaped base bulb, when the base portion is inserted into the socket, the electrodes extending on the base portion come into contact with the contacts provided on the socket to be electrically connected. Figure 13 It is a partially cutaway perspective view of an example of a conventional lamp holder. The base part 31 of the wedge-shaped base bulb 30 is formed in a plate shape integrally with the bulb part 35 , and filaments are provided e...
