の結合構造に関するものである。[Detailed description of the invention] [Field of industrial application] The present invention is applied to a light bulb with a base (halogen light bulb) used as a light source for automobile headlights, etc., especially the pinch seal part at the rear end of the bulb and the base plate. This relates to the bond structure with.

For example, as a conventional light bulb with a cap,
-What was described in Publication No. 12706 and Utility Model Application Publication No. 1983-
There is one described in Publication No. 35268.

ル部を挾持するようにしている。 In the former case, as shown in FIG. 6, a lug 12 that presses a wide surface of the pinch seal portion of the valve is provided on the mouth plate 11, and extends from the mouth plate toward the free end of the pinch seal portion, and has a curved shape. On the other hand, the pinch seal portion is provided with protrusions corresponding to the lugs 12, so that the pinch seal portion is held between the corners of the lugs 12.

あるいは近接させた結合構造としている。 The latter has at least one pair of intermediate holding pieces (intermediate lugs) on its base plate 21, as shown in FIG.
22 and at least two pairs of side holding pieces (upper stage lugs) 23, while the pinch seal portion of the valve is provided with a protrusion and a protrusion that engages with the intermediate lug 22, and the outer side of the upper lug 23 is The coupling structure is in contact with or close to the protrusion.
ところで、ピンチシール部を小さい圧力で保持

By the way, in order to hold the pinch seal part with small pressure, it is necessary to increase the interval between the lug holding parts, but in the former case, the lug 12 is formed downward like the other lugs, so the lug 12 is The holding interval cannot be increased unless the cut is made deeper. In other words, the contact points of each lug with the valve are close to each other in the vertical direction, making it difficult to hold the lug with a small pressure.

外力に対して弱く、ガタが生じ易い。 On the other hand, in the latter case, even if the lugs 22 and 23 are in the opposite direction and the upper lug 23 is facing upward, it still engages with the neck of the valve, so the elasticity of the cap plate is not utilized when the valve is fitted, and the valve is overloaded. There is a risk of stress being applied. Further, since there is no lug that presses the narrow surface of the pinch seal portion, it is weak against external force from that direction and is likely to rattle.

The present invention provides a light bulb with a cap, which includes a bulb having a pinch seal portion with a substantially rectangular cross section at the rear end, and a metal cap plate assembled to the pinch seal portion of the bulb, wherein the cap plate is located at the center of the bulb. A recess is provided in the part, and a pair of lugs facing downward are formed on the bottom surface of the recess to press the wide surface of the pinch seal part, and a pair of lugs are formed facing downward on the plate surface around the recess, and a pair of lugs are provided on both sides of the lugs to hold the pinch seal part. The present invention is characterized in that two pairs of lugs that engage with the neck portion or the projections thereon are formed downward, and a pair of lugs that press the narrow surface of the pinch seal portion are formed upward.
以下、本考案を図示の実施例に基づいて詳細に
説明する。
Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

る。 Further, the cap plate 3 is provided with a recess 3A in the center thereof, and the pinch seal portion 2 is provided in the bottom surface of the recess 3A.
A pair of lugs 4 corresponding to the wide surfaces of the cap plate are formed by punching, while two pairs of lugs 5 are formed on the surface of the base plate so as to be located on both sides of the pair of lugs 4. Furthermore, a pair of lugs 6 are formed on the cap plate 3 to press the narrow surface of the pinch seal portion 2. This lug 6 is the same as the lugs 4 and 5.
On the contrary, it faces upward, and its tip is bent outward. Each of the lugs 4 to 6 is rounded at its tip and bent portion. Furthermore, at the same time as each of the lugs 4 to 6 is formed, an opening 7 for inserting the pinch seal portion is formed.

堅固な結合状態となる。 With this structure, when the cap plate 3 is assembled to the valve 1, the wide surface of the pinch seal portion 2 is pressed down and firmly held by the pair of lugs 4, and the lugs are held above both sides of the pinch seal portion 2. 5. Since the contact points of both lugs 4 and 5 have a large distance x in the vertical direction, sufficient holding force can be obtained with a small pressing force. Further, the narrow surface of the pinch seal portion 2 is pinched by the lugs 6, and the position in that direction is restricted. That is, a solid bonded state with no looseness is achieved.

As described above, according to the present invention, a concave portion is provided in the center of the base plate, and lugs are formed on both sides with a step to press down the wide surface of the pinch seal portion, so that the contact point of both lugs with the pinch seal portion is The interval (dimension x) can be increased, and firm holding can be achieved with small pressure. Further, since the lug that presses the narrow surface of the pinch seal portion is formed facing upward, it serves as a guide when the valve is inserted, and the valve can be inserted smoothly and appropriately. Furthermore, since the contact position of the lug with the pinch seal is above the plate surface, the moment when stress is applied to the valve head is smaller than on the plate surface or below the plate surface, and the valve is firmly fixed. Become.
