Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a light bulb socket cap retainer fitting that can be fitted with a light bulb socket cap without damaging the reflector of a signal lamp.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, a signal lamp has a translucent lens b attached to the front surface of the signal lamp a, the inner surface of the signal lamp a has a mirror surface, and a light bulb c is provided on the base end side of the signal lamp a. It is configured to be mounted. Therefore, as shown in FIG. 6, the light bulb c is attached to the light bulb socket base d, and then the light bulb socket base d is fitted into the rising portion e opened at the base end side of the signal lamp a. Further, the mechanism is such that it is fixed by 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, since the pressing metal fittings g are attached to the reflecting plate f by the fastening member h such as a screw, a part of the fastening member h is projected on the reflecting mirror i surface inside the signal lamp a. As a result, the reflection effect and the reflection efficiency are reduced. Further, when the light bulb socket base d is attached by the metal fittings g, 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. Therefore, in order to solve the above problems, it is an object of the present invention to provide a holding metal fitting that can easily mount a light bulb socket base to a signal lamp without applying a load to a reflector. .

[0004]

Means for Solving the Problems The above object of the present invention can be achieved by a pressing metal member having the following configuration. That is, the gist of the invention is a pressing metal fitting for fitting and coupling 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 storage tube protruding in the center thereof, such as a thin steel plate. The two upper elastic plates and the lower elastic plate formed by are fixed in a state that they intersect each other at a substantially right angle, and the socket housing tube can be inserted in the center of the socket housing tube in a loose insertion manner. The bottom elastic plate is made larger than the diameter of the bulb socket base, both ends of the upper elastic plate are bent downward, and the ends are bent inward to form a mooring part. Moreover, it is a light bulb socket cap fitting for traffic signal lights, characterized in that its overall length is almost the same as that of the light bulb socket base.

[0005]

[Action]

 As shown in FIG. 4, the holding metal fitting of the present invention can easily push down the holding portions 6 and 6 of the upper elastic plate 1 in a downward direction from the state shown by the phantom line in the figure to easily push the bulb socket base 7 Can be fitted and connected to the light bulb socket base fitting hole 9. 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 is applied, and the engagement with the locking portion 11 can be maintained. 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 can be easily released by manually pushing down the pressing portions 6 and 6. It will be possible.

[0006]

【Example】

 A light bulb socket cap holder according to the present invention will be described in detail below with reference to the drawings showing an embodiment thereof. 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 a thin steel plate are crossed with each other at a substantially right angle, and screwed by screws 3 and 3. Fix it. Further, 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 ends of the upper elastic plate 1 are formed to be bent downward, and the tips thereof are bent inward to anchor the mooring portion. It is set to 5. 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 storage tube insertion hole 4 of the light bulb socket base 7 is inserted into the socket storage tube 8 while the lower elastic plate 2 is curved inward. Both ends are pushed into the light bulb socket base 7, and as shown in FIG. 3, the light bulb socket base 7 is inserted into the light bulb socket base fitting hole 9 of the signal light device 13, and the pressing parts 6 and 6 are pushed down. As a result, the upper elastic plate 1 is pushed down while resisting the urging force of the lower elastic plate 2, and the mooring portions 5, 5 at both ends thereof are formed at the tip peripheral edge of the rising portion 10 of the light bulb socket cap fitting hole 9. It is configured to be moored to the locking portion 11 and to be connected in a hermetically sealed manner. Note that reference numeral 12 in the drawing denotes a waterproof rubber packing.

[0008]

[Effect of device]

 As described above, according to the present invention, since it is not necessary to attach the holding metal to the reflector, it is possible to easily attach the bulb socket cap without damaging the reflector in the signal lamp. It will be. Also, since the spring effect is sustained by the two elastic plates, it is most effective as a metal fitting for a light bulb socket cap of a signal lamp that requires waterproofness.
