US 2002/0171527 A1 · Socket for lamp transformer for lamp, and method of manufacturing transformer for lamp

Abstract

Providing a high-voltage-side terminal with means for preventing a core inserted into a central hole of a bobbin from getting out of position securely fixes the core to the predetermined position, at the time a transformer which is a part of an ignitor is assembled, during the work proceeds from the inserting step of the core to the next step. Thus, at the time the ignitor-integral type bulb socket is assembled, the core hardly moves out of the predetermined position and there is a less possibility that the core gets out of position. Accordingly, this does not require so high machining accuracy of both members and reduces the cost for machining the product as well as for inspecting the dimension control or the like.

Dependent claims

A socket for a lamp comprising:

a bobbin around which a primary coil and a secondary coil are wound;
a core which is inserted into said bobbin;
a high-voltage terminal, provided on said bobbin, for connecting said secondary coil and a high-voltage-side contact of the lamp, a transformer which is made up of said bobbin, said core, and said high voltage terminal;
an ignitor which is made up of said transformer and a capacitor;
a socket for receiving therein said ignitor and for inserting thereinto, and fixing thereto, said lamp;
and
a filler member which is filled around said transformer;
wherein a retaining means for retaining said core is provided on said high-voltage terminal.
