Description of the Related Art For example, a rod-shaped incandescent lamp used as a light source for exposure of a copying machine has a ceramic base attached to a pressure-sealing portion at an end of a sealing body. In the case of a lead wire type incandescent lamp, this base is held by a holding piece and the incandescent lamp is attached to a copying machine. An example of a conventional incandescent lamp base will be described with reference to FIG.
It is made by cutting a cylindrical body from the end face into a forked shape,
A flat crimp sealing portion at the end of the incandescent light bulb is inserted between the connecting portions 3 and 3, and is bonded with, for example, an alumina cement-based inorganic adhesive. Then, a lead wire is connected to a lead pin extending from the crimp sealing portion in the base, and the lead wire extends from an inner hole 11 of the cylindrical holding portion 1, and a metal mounting piece is fixed to the holding portion 1. Attached to the copier.

ある。By the way, although the adhesive inevitably protrudes slightly from the end 3a of the connecting portion 3, the adhesive is in contact with the connecting portion between the lead pin and the lead wire. The solidified adhesive is porous and easily absorbs moisture, so that the adhesive has conductivity. In other words, the adhesive protruding from the lead pin of the incandescent lamp and the end 3a of the connection portion 3 is conducting. Therefore, the end of the connection 3
It is necessary to increase the creepage distance between the adhesive protruding from 3a and the holding piece fixed to the holding portion 1, and a large-diameter flange portion 5 is formed between the connecting portion 3 and the holding portion 1. Then, in order to form the flange portion 5, the outer peripheral surface of the connection portion 3 is cut out,
A step 51 is formed. For this reason, the production was troublesome and the production cost was high. Therefore, the present invention aims to provide a base for an incandescent light bulb with a lead wire which can secure a sufficient creepage distance without cutting a step portion, is easy to manufacture and inexpensive. is there.

が形成されたことを特徴とする。A base for an incandescent lamp according to the present invention includes a cylindrical holding portion through which a lead wire is inserted, and a cylindrical intermediate portion formed continuously from the holding portion to have a large diameter. The outer peripheral surface extends from this intermediate portion with the same diameter and is formed in a forked shape,
The incandescent light bulb is characterized in that it comprises a connecting portion into which a crimped sealing portion at the end of the envelope is inserted and adhered, and flat portions are formed at both ends in the radial direction of the connecting portion.

できてコストを低減できる。In such an incandescent lamp base, the intermediate portion corresponding to the flange portion of the conventional example and the outer peripheral surface of the connecting portion have the same diameter, but flat portions are formed at both radial ends of the connecting portion. The radial length of the connecting portion is reduced. That is, a step is formed between the inner end of the connecting portion and the outer peripheral surface of the intermediate portion. Therefore, a sufficient distance is provided between the adhesive protruding from the end of the connection portion and the outer peripheral surface of the intermediate portion, and the creepage distance is accordingly increased. Further, since the outer peripheral surfaces of the intermediate portion and the connecting portion have the same diameter, a shaving step is not required, so that it is possible to manufacture easily and reduce the cost.

The inner diameter is larger than that of the two, and an inner hole 11 is formed inside both. The outer peripheral surface of the connecting portion 3 extending in a bifurcated manner from the intermediate portion 2 has the same diameter as the intermediate portion 2. Also, flat portions 31 are formed at both ends in the radial direction of the connection portion 3 respectively. Therefore, the ridgeline 31a inside the plane portion 31 and the intermediate portion 2

Flat crimp sealing part formed at the end of the envelope 8 of the incandescent lamp
81 is inserted between the connecting portions 3 and 3, and the lead wire 82 connected to the external lead of the incandescent lamp is drawn through the inner hole 11 from the rear end of the holding portion 1. Then, an adhesive 9 is injected to bond the compression-sealing portion 81 to the connection portion 3. At this time, the adhesive 9 slightly protrudes from the inner ridgeline 31a of the plane portion 31,
Since there is a step between the ridge 31a and the outer peripheral surface of the intermediate portion 2, a sufficient space can be provided between the protruding adhesive 9a and the outer peripheral surface of the intermediate portion 2. Therefore, when the metal mounting piece is fixed to the holding portion 1 and mounted on the copying machine, the adhesive 9a
A sufficient creepage distance can be provided between the mounting portion 1 and the metal mounting piece fixed to the holding portion 1. In addition, since the outer peripheral surface of the connecting portion 3 extending in a bifurcated manner from the intermediate portion 2 has the same diameter as the intermediate portion 2, molding can be performed without shaving. Therefore, it can be easily manufactured and cost can be reduced.
