Description

[Detailed Description of the Invention] This invention relates to a holding device for two halogen bulbs used in automobile headlamps, fog lamps, etc.

Conventionally, this type of holding device for two valves in a halogen medium has a structure as shown in FIG.

That is, first, in the figure, a shows a two-way halogen bulb specified by the ECE standard, and a pair of fittings d are attached to both sides of a pinch seal portion C formed at one end of the bottom of the valve body.

d', and the mounting brackets d and d' on both sides have gripping parts e and e' for gripping the pinch seal part C, and are formed with a through hole f and a notch g.

The holding device ff1H to which the two halogen medium valves a is attached consists of a fixed insulating base i and a pair of L-shaped plates protruding from one side of the base i with a proximal rising plate part. and the support pieces j, j' with the proximal end hanging plate part connected to one side of the base i.
It consists of a pair of spring pieces protruding to face each other, and a positioning pin l near the tip of the support piece i, and a cutout near the tip of the support piece j'. A cutting piece m is formed, and the mounting brackets d and d' are mounted on the supporting pieces j and j', and the through hole f and pin l are cut out by cutting out the cutout g and cutting out the piece. m, and in this state, the two halogen valves a are held under pressure by pressing the gripping parts e and e' with the spring pieces from above.

Note that the support pieces j and j' and the spring pieces k and '
The proximal end thereof is fixed by crimping with eyelets together with separate terminals n and n' joined to the other side of the base i.

In this conventional and halogen medium 2 valve holding device H,
The halogen H2 bulb a itself is small, and if you hold the bulb body b (bulb part) with your fingertips when installing it, hand oil will stick to it, and when the bulb is turned on, the oil will get burned and cause a reduction in the amount of light. While holding the mounting brackets d and d' on both sides with your fingertips, attach them to the pair of support pieces j and j' and the spring piece of the holding device H.
The installation is carried out by inserting the slide so that it is pushed between the two and clamping the spring piece k.

Since k' is already in contact with support pieces j and j, and the pin l and cut and raised piece m protrude near it, the mounting brackets d and d' are connected to support pieces j and j and the spring piece. ni'
It is difficult to slide the spring pieces between each other while pushing up the spring pieces, resulting in poor installation workability.

This idea was created in view of the above circumstances, and its purpose is to provide a holding device with extremely good workability that allows two halogen medium bulbs to be inserted very easily and smoothly and securely held under pressure. It is in.

That is, this invention is characterized by a holding device in which each spring piece facing a pair of support pieces is provided with an operating lever for moving the spring pieces in a direction in which the spring pieces are moved away from the support pieces when the valve is inserted.

An embodiment of this invention will be described below with reference to FIGS. 2 to 7.

First, FIG. 2 is a cross-sectional view of the holding device of this invention applied to an auxiliary lighting lamp such as a fog lamp of an automobile. The main structure consists of a substantially paraboloid of revolution reflector (reflector) 5 that is fitted into the housing 2 through a rim 4 with its front surface covered with a lens 3, and the rear surface of the reflector 5. bracket) 6.6'
A holding device 8 of the present invention is fitted and fixed in the center opening of the reflector 5 so as to be compressed by a mounting spring 7 whose both ends are locked. The two valves 9 remain attached.

Here, the second halogen bulb 9 is the same as described above, and the third

Also, the pair of support pieces 11 and 11' have horizontal plate parts 11a and 11a' and a rising plate part 1 at the base end thereof, respectively, as shown in FIG.
1b and 11b', one horizontal plate part 11a has a positioning pin 11 on the top of the horizontal plate part 11a.
C projectingly, and a cut-and-raised piece 11d is provided on the other horizontal plate portion 11a' near the end.

On the other hand, there are eyelet holes 11e in the rising plates 11b and 11b'.
, 11 e', and power supply connection terminals 11 f and 11 f' extending integrally in opposite directions.

The pair of spring pieces 12 and 12' are symmetrical to each other, and as shown in FIG. 7, they are composed of a road-shaped plate spring consisting of an inclined plate part 12a and a hanging plate part 12b at its base end. , has an eyelet hole 12C in the hanging plate part 12b, and a bending protrusion 1 at the tip and approximately the middle of the inclined plate part 12a.
It has a structure having 2 d and 12 e.

As shown in FIG. 7, each of the operating levers 13 and 13' is made of a thin rod, and both ends 13a and 13b are bent into an L-shape.

The holding device 8 having the above-mentioned structure holds the pair of support pieces 11 and 11 in the horizontal plate portions of the insulating base 10 by inserting them into the left and right support piece passage portions 10C and 10C' from behind. 11a and 11a' protrude toward the front of the base 10 in a substantially right angle direction and are mounted so that the proximal end rising plate parts 11b and 11b' are joined to the rear surface of the base 10, while the pair of spring pieces 12 and 12' are attached to the support pieces. 11.11 horizontal plate part 1
1 a and 11 a', and their proximal hanging parts 12 b and 12 b are joined to the front left and right parts of the base 10 so as to face each other above, and in this state, crimps 14 and 14' are provided on the left and right parts respectively, and the base 10 is attached The support piece 11.11' and the spring piece 12.12' are assembled and fixed.

The pair of spring pieces 12.12' has an operating lever 13. along the front surface of the inclined plate portion 12a12a.
