Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a mounting structure for a light guide tube used for checking the lighting of headlights, taillights, etc. of automobiles.

(Technical background) In order to confirm the lighting of lamps that cannot be seen directly by the driver or through various mirrors, a portion of the light emitted from the lamps is guided through a light guide tube (optical fiber) to illuminate the display. Sometimes it is light.

In that case, it is desired that the light guide tube be easily attached to the lamp.

(Object of the invention) An object of the invention is to provide a light guide tube mounting structure that allows the light guide tube to be easily placed in a predetermined position of a socket.

(Summary of the invention) The present invention provides curled parts that can be locked to each other at both ends of the long belt of the holder, which has long and short parallel belts that are connected in part, and are wrapped around the light bulb socket, and the curled portions engage with each other to hold the light bulb socket, and the short band of the holder holds and fixes the light guide tube, so that the light guide provided in the light bulb socket A light guide tube and the short band holding the light guide tube are inserted into the tube insertion hole, and the short band is provided with a cut-and-raised part to prevent the light guide tube from being pulled out from the light guide tube insertion hole. A prism is attached to one end of the light guide tube to collect the light emitted from the light bulb.

(Embodiment) Figures 1 to 3 show an embodiment of the present invention, in which 1 is a light bulb socket, 2 is a light guide tube (optical fiber), and 3 is a light guide tube 2 connected to the socket 1. A holder for attachment, 4 is a light bulb attached to the socket 1, and 5 is a lighting lens (prism) attached to one end of the light guide tube 2.

The holder 3 has long and short parallel bands 3A and 3B that are connected in some parts, and is formed so that the longer band 3A has curled parts 3c and 3C' that can be locked to each other at both ends. The light guide tube 2 is connected to the other band 3B.
Hold and secure the socket 1 with the longer band 3A.
is held by the engagement of the curled portions 3C and 3C'. Further, the shorter band 3B is provided with a cut-and-raised portion 3D to prevent the socket 1 from being pulled out from the light guide tube insertion hole 1A.

With the above structure, the light guide tube 2 is inserted into the insertion hole 1A of the socket 1 with the holder 3 attached, and the longer band 3A is inserted into the socket 1.
After the cut and raised portion 3D has come out to the front, it is pulled back and positioned to engage the curled portions 3C and 3C', thereby completing the attachment of the light guide tube 2 to the socket 1. After the installation of the light guide tube 2 is completed, the lens 5 is installed. Also, when removing the light guide tube 2, press the cut and raise 3D while pressing the light guide tube 2.
When the socket 1 is rotated as shown by the arrow a in FIG. 1, the curled portions 3C, 3 of the holder 3
C' is disengaged and can be removed.

(Effects of the invention) As described above, according to the invention, a holder having long and short parallel bands that are partially connected is provided with curled parts that can be locked to each other at both ends of the longer band. , the longer band wraps around the light bulb socket, and the curled parts engage with each other to hold the light bulb socket, and the shorter band of the holder holds and fixes the light guide tube to hold the light bulb socket. A light guide tube and the short band holding the light guide tube are inserted into the light guide tube insertion hole provided in the light guide tube insertion hole, and the short band prevents the light guide tube from being pulled out from the light guide tube insertion hole. Since the light guide tube is positioned with a cut-and-raised part, it is easy to attach and remove the light guide tube, and the light guide tube can be easily placed in the specified position of the socket, making it possible to securely attach the light guide tube. become.
