Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a halogen incandescent light bulb of double-end sealed type, which is suitable as an interior lamp for a microwave oven and a microwave oven.

[0002]

[Prior Art]

 Conventionally, ordinary incandescent lamps have been used as internal lamps for microwave ovens and microwave ovens, but there is a problem that the amount of light is insufficient, and the use of halogen incandescent lamps has recently been considered. This halogen incandescent light bulb uses a rod-shaped both ends sealed type in order to brightly illuminate the entire interior, and as the both ends sealed type, a contact type and a lead wire type are known.

Since the interior light used in a microwave oven, a microwave oven, etc. is lit under various gas atmospheres when cooking, a contact type in which conductivity failure easily occurs due to oxidation is not preferable, When the lead wire type is used for a microwave oven, the heat resistance of the coating resin is required. However, the heat resistance of this coating resin is not sufficient, and under the present circumstances, in the case of the microwave oven, it is the fact that the thermal effect is reduced by illuminating from the lateral direction inside the refrigerator. On the other hand, in the case of a microwave oven, even a lead wire type has sufficient heat resistance, so it is preferable to use the lead wire type because it is easier to install.

[0004]

[Problems to be solved by the device]

 Illuminating from the side of the range makes it difficult to secure sufficient brightness in the refrigerator, and there is the problem that the shadow of the food is almost invisible. In addition, the use of an incandescent lamp having separate mounting members for the microwave and the microwave oven has a problem that a common incandescent lamp cannot be used.

The present invention has been made to solve the above problems, and the purpose thereof is that it can be attached to the upper part of a microwave oven and has heat resistance in the case of a microwave oven. The objective is to provide a halogen incandescent light bulb that is sealed at both ends and that can be installed with sufficient security and can be used as a lead wire type in the case of microwave ovens.

[0006]

[Means for Solving the Problems]

 The both-end sealed halogen incandescent lamp of the present invention includes a plate-shaped terminal connected to an external lead rod extending outward from the sealed parts at both ends, and an external lead and a plate-shaped terminal fixed to the sealed part. In a halogen incandescent light bulb with both ends sealed, which comprises a base that covers the part, the plate-shaped terminal includes a screw fixing part having a long hole through which a screw is inserted and a narrow width extending outward from the screw fixing part. It is characterized in that it comprises a faston terminal fixing portion formed on.

[0007]

[Action]

 Since the screw fixing part of the plate-shaped terminal can be fixed directly to the power feeding part in the refrigerator with a screw, it is suitable for a microwave oven. The faston terminal fixing part can be directly connected to the lead wire by attaching the faston terminal to the tip of the lead wire, which is suitable for microwave ovens.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of an embodiment of the present invention, which is a halogen incandescent lamp having a rating of 100V and 50W. In this figure, 1 is a bulb, 2 is a filament, 3 is an anchor, 4 is a base, and 5 is a plate-like terminal.

The No. 1 valve has a gas of bromine and krypton enclosed in a quartz glass having a wall thickness of 1.0 mm, an outer diameter of 8.0 mm, and a length of 74.0 mm. A filament 2 wound in a coil shape is arranged in the valve 1, and the filament 2 is arranged at an anchor 3 along the tube axis of the valve 1.

A pinch-sealed sealing portion 11 is formed at both ends of the valve 1. A metal foil 21 is embedded in the sealing portion 11 and an internal lead 22 and an external lead 23 are connected. There is. The base 4 is fixed to the sealing portion 11 with an adhesive. The base 4 is divided by a central ring portion 41 into a sealing portion fixing portion 42 and a mounting portion 43, and a plate-shaped terminal 5 is connected to the external lead 23 and extends from the mounting portion 43. The plate-like terminal 5 is composed of a screw fixing portion 51 having a long hole formed on the base side and a faston terminal fixing portion 52 extending outward from the screw fixing portion 51.

FIG. 2 is a partially enlarged view of the plate-shaped terminal 5 mounted using the screw fixing portion 51. The screw 6 is directly connected to a power feeding portion (not shown) attached to the device side, Fix the incandescent light bulb. According to this mounting method, the lead wire connected to the power supply is hidden in the shadow of the equipment and is not exposed at the part where heat resistance is required.Therefore, when installing it in a high temperature area such as an oven range. This is a particularly preferable use example.

FIG. 3 is an enlarged view of a portion of the plate-shaped terminal 5 mounted using the faston terminal fixing portion 52. The faston terminal 8 attached to the tip of the coated lead wire 7 is fastened to the faston terminal fixing portion. 52 is directly inserted. In this case, the mounting portion 43 of the base 4 is fixed to the device side, and the coated lead wire 7 extends to the power feeding portion (not shown). This mounting state is relatively simple, but since the lead wire 7 is used, it is suitable for installation in equipment or places where heat resistance is not required so much.

As can be seen from the embodiments shown in FIGS. 2 and 3, since the present invention is a halogen incandescent light bulb of both ends sealed type that allows two types of connection methods, it is possible to connect to equipment without increasing the number of parts. The mounting method can be selected appropriately by taking into account the mounting conditions.

[0014]

[Effect of the device]

 As described in detail above, the halogen incandescent bulb of the present invention, which is sealed at both ends, can be attached by a lead wire or by a screw, and is therefore suitable as an interior lamp for a microwave oven or an electronic range. It is possible to support two types of mounting methods without increasing the number of points.
