Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an optical fiber holder

The present invention relates to an optical fiber holder of a light emitting type indicator, and more particularly, to an optical fiber holder of a light emitting type indicator, which is fixed by mutual fastening force of a fastening part and a fixing nut at both ends with respect to a panel, To an optical fiber holder of a light-emitting type indicating plate which is easy to assemble together with ease of disassembly and fixing force by fastening.

Generally, all roads, such as city roads, national roads, and highways, have road signs that provide road information to drivers. These road signs are attached with reflective paper made in letter, number or symbol form on a plate made of iron plate or aluminum and reflect the light of the vehicle through the reflection paper to provide road information to the driver.

However, in the case of a conventional road sign, the identification of the signboard is relatively easy in the bright surroundings of the day, but in the dark as in the night, the identification range by the reflex reflection is limited to narrow angles. In the case of roads for high-speed driving, since the distance recognized by the driver is short, it is possible to identify only by approaching at a relatively short distance, and the risk of a traffic accident is extremely high.

As shown in FIG. 1, the front end portion of the optical fibers 3 and 4 are arranged from the back surface to the front surface so as to form a pattern or phrase to be displayed on a panel provided as a plate- And the light source 5 is provided to the optical fibers 3 and 4 so as to emit light in various colors to perform a display function.

Further, the light source 5 is formed behind the bundle 7 that binds a plurality of optical fibers 3,4.

However, in the road sign using the conventional optical fiber described above, the optical fiber is inserted into the fixing hole formed in the panel, and then the optical fiber is fixed by the bonding operation method in which the adhesive is applied, so that the fixing force is changed according to the application amount of the adhesive, There is a problem.

In addition, if the fixing hole formed in the panel is not in good condition, the inserted optical fiber is damaged in the state where the burr remaining in the fixing hole is generated, and the display function of the optical fiber is interfered with, have.

Further, when the fixing hole is formed to be larger than the optical fiber, the optical fiber can not be easily fixed, and the foreign substance due to the bonding operation for fixing remains on the panel, thereby losing the reliability of the product, such as the lack of completeness.

In this case, it is not limited to the road sign, but it is possible to use various signboards, such as a general signboard, a signboard for various roads and sidewalks, a traffic guide signboard for a city, a highway bus, It also applies to sign boards, sign boards, billboards,

Next, an optical fiber holder for an advertisement apparatus using an optical fiber of Korean Patent Registration No. 10-612475 (2006.08.16, published), which is proposed in order to solve the above problems, Likewise, an advertising panel 52 provided as a sheet-like member in front of the frame 51 provided in a box type, and advertisement holes 53 and 54 formed to constitute a pattern or character to be displayed on the advertisement panel 52 An optical fiber 55 and 56 inserted and fixed in the advertisement holes 53 and 54 and a bundle 57 as a binding material of the optical fibers 55 and 56 protruding rearward of the advertisement panel 52 And a light source (59) for providing light to the light emitting means in the bundle (57), characterized in that the advertisement panel (52) is provided with an optical fiber (55, The optical fiber holder 60 can be easily fixed.

The optical fiber holder 60 includes an insertion portion 61 provided at a front side to be inserted into the advertisement holes 53 and 54 and a rear portion located behind the insertion portion 61 to be engaged with the advertisement panel 52 A holder body 65 including a jaw 62 and a contact portion 63 which is raised from the insertion portion 61 and a holder body 65 formed in the insertion portion 61 and passing through the advertisement holes 53 and 54 And a locking protrusion 66 for preventing the inserted optical fiber holder 60 from being detached from the front surface of the advertising panel 52 in a state where the optical fibers 55 and 56 are inserted, And an induction hole 69 formed to enlarge the diameter of the inlet 68 so that the optical fibers 55 and 56 can be inserted more easily.

Accordingly, it is possible to more easily fix the optical fiber by providing a holder for fixing the optical fiber to the advertisement panel more easily, thereby improving the productivity of the billboard and improving the visibility of the billboard .

However, since the conventional optical fiber holder does not include fixing means or function between the optical fiber holder and the optical fiber inserted in the optical fiber holder, the optical fiber is easily detached from the optical fiber holder during the manufacturing process, There is a problem that the efficiency is lowered.

In the conventional optical fiber holder, the width between the jaw protrusions and the engagement jaws is related to the thickness of the advertisement panel. For example, when the thickness between the jaws and the jaws is smaller than the thickness of the advertisement panel, Is not fixed.
