BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light bulb socket cap holder for mounting a light bulb socket cap without damaging a reflector of a signal lamp.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a signal lamp has a translucent lens b mounted on the front surface of the signal lamp a, the inner surface of the signal lamp a is a mirror surface, and the base end of the signal lamp a. The light bulb c is mounted on the side. Therefore, as shown in FIG. 6, the bulb c has a bulb socket base d.
After being mounted on the
It is a mechanism that is fitted in the rising portion e opened to the base end side of the above and is further fixed by the pressing metal fittings g to which the reflecting plate f of the signal lamp a is mounted.

[0003]

[Problems to be solved by the device] However, in the above mechanism,
In order to mount the press fittings g, g on the reflection plate f by the fastening member h such as a screw, a part of the fastening member h is projected on the reflection mirror i surface of the inner surface of the signal lamp a, and as a result, This causes a reduction in reflection effect and reflection efficiency. Further, when the light bulb socket base d is attached by the metal fittings g, if the work is performed while holding the reflection plate f by hand, the pressure may distort or damage the reflection mirror i. Further, there is a problem that the urging force of the press fitting g is lowered over a long period of time. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has an object to provide a holding metal fitting that allows a light bulb socket base to be easily attached to a signal lamp without applying a load to a reflector. .

[0004]

The above object of the present invention can be achieved by a pressing metal member having the following structure. That is, the gist of the invention is a pressing metal fitting for fitting and connecting a light bulb socket base fitting hole opened at the base end side of a signal lamp and a light bulb socket base having a socket housing tube protruding in the center thereof, such as a thin steel plate. The two upper elastic plates and the lower elastic plate formed by the above are fixed in a state of intersecting each other at a substantially right angle, and the socket housing tube insertion hole into which the socket housing tube can be inserted freely Further, the total length of the lower elastic plate is larger than the diameter of the light bulb socket base, and both ends of the upper elastic plate are bent downward, and the tips thereof are bent inward to form a mooring portion, Moreover, the light bulb socket cap fitting for a traffic signal lamp is characterized in that its entire length is substantially the same as the bulb socket cap.

[0005]

The holding metal fitting of the present invention, as shown in FIG. 4, changes from the state shown by the imaginary line in the drawing to the holding portions 6, 6 of the upper elastic plate 1.
It is possible to easily fit and connect the light bulb socket base 7 to the light bulb socket base fitting hole 9 by pushing down with a hand. Then, after that, the urging force of the lower elastic plate 2 constantly exerts a force to push the upper elastic plate 1 upward, so that the mooring portions 5 and 5 at both ends of the upper elastic plate 1 move inward. The force acts, and the engagement with the locking portion 11 can be maintained. Further, when the engagement between the mooring portions 5 and 5 and the locking portion 11 is released, the pressing portions 6 and 6 of the upper elastic plate 1 are again provided.
Can be easily released by pushing down with a hand.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The light bulb socket cap holder according to the present invention will be described below in detail with reference to the drawings showing the embodiments. FIG. 1 is a perspective view of the present invention, in which two upper elastic plates 1 and two lower elastic plates 2 made of thin steel plates are fixed to each other with screws 3 and 3 in a state where they intersect each other at a substantially right angle. Let The socket accommodating cylinder insertion hole 4 is provided at the center of the upper elastic plate 1 and the lower elastic plate 2.
Therefore, the total length of the lower elastic plate 2 is set to be larger than the diameter of the bulb socket cap, and both side ends of the upper elastic plate 1 are
The mooring portion 5 is formed by bending it downward and bending its tip inward. Further, the entire length of the upper elastic plate 1 is made substantially the same as the diameter of the bulb socket cap. Further, the pressing portions 6, 6 are formed so as to project from both ends of the center of the upper elastic plate 1.

Therefore, as shown in FIG. 2, the socket accommodating tube insertion hole 4 is inserted into the socket accommodating cylinder 8 of the bulb socket base 7.
While the lower elastic plate 2 is bent inward at the same time as inserting, the both ends of the lower elastic plate 2 are pushed into the light bulb socket base 7, and as shown in FIG. By inserting the bulb socket base 7 into the inside and pushing down the pressing portions 6, 6, the upper elastic plate 1 is pushed down while resisting the urging force of the lower elastic plate 2, and the mooring portions 5 and 5 at both ends thereof are It is configured such that it is moored to a locking portion 11 formed on the peripheral edge of the leading end of the rising portion 10 of the light bulb socket cap fitting hole 9 and is connected in a hermetically sealed manner. Note that reference numeral 12 in the drawing denotes a waterproof rubber packing.

[0008]

As described above, according to the present invention, since it is not necessary to attach the holding metal to the reflector, the reflector in the signal lamp is not damaged and the bulb socket base can be easily attached. It is possible to do.
Further, since the spring effect is maintained by the two elastic plates, it is most effective as a metal fitting for a light bulb socket cap of a signal lamp which requires waterproofness.
