Abstract

A wiring terminal with 90-degree bent light guide columns comprises a shell and the light guide columns arranged in the shell, and is characterized in that the sections of the light guide columns are in an inverted-L shape, and the L-shaped light guide columns are in circular arc transition on the bent portions. Compared with the prior art, the wiring terminal has the advantages that the light guide columns are designed to be in an inverted-splay shape, light condensation ends and visual ends are in 90-degree circular arc transition, a light source can be reflected to the visual ends along circular arcs, and therefore 90-degree turning light guiding is achieved.

Description

A kind of binding post with 90 degree bent angle light-guiding pillars

Technical field

The utility model relates to a kind of binding post with 90 degree bent angle light-guiding pillars.

Background technology

The light of existing equipment indicator lamp is mostly by straightline propagation, the light source launch point of lighting apparatus and acceptance point will be arranged on same straight line, but, in the situation that device structure and installing space are restricted, many times the point of observation of the launch point of light source and reception light source cannot be located along the same line, according to traditional light source trend, be just difficult to reasonably arrange, thereby cannot realize normal illumination.

Utility model content

Technical problem to be solved in the utility model is for above-mentioned prior art present situation, to provide a kind of light source arrangement more flexibly with the binding post of light-guiding pillar.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of binding post with 90 degree bent angle light-guiding pillars, include housing and be arranged at the light-guiding pillar in this housing, it is characterized in that: the cross section of described light-guiding pillar is inverted L-type, this L-type light-guiding pillar is arc transition at crooked bending part.

As preferably, L-type one end opening of described light-guiding pillar is straight-tube shape and corresponds to optically focused end, and the L-type other end opening of this light-guiding pillar is back taper and corresponds to ocular end.

As preferably, described light-guiding pillar is also provided with U-shaped clamping part in the bending part inner side of L-type.

As preferably, in described housing, include a plurality of described light-guiding pillars that are arranged side by side.

Compared with prior art, the utility model has the advantage of: light-guiding pillar design is become to herringbone shape, in the middle of optically focused end and ocular end, be 90 degree arc transition, make light source to reflex to ocular end along circular arc, thereby realize 90 degree turning leaded lights.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figure 1 to 4, the present embodiment relates to a kind of binding post with 90 degree bent angle light-guiding pillars, and this binding post includes housing and is arranged at the light-guiding pillar 1 in this housing, includes a plurality of light-guiding pillars that are arranged side by side 1 in housing.

Wherein, the cross section of light-guiding pillar 1 is inverted L-type, and this L-type light-guiding pillar 1 is arc transition at crooked bending part 11; L-type one end opening 12 of light-guiding pillar 1 is straight-tube shape and corresponds to optically focused end, and light source 2 enters in light-guiding pillar 1 by this optically focused end-fire, and the L-type other end opening 13 of this light-guiding pillar is back taper and corresponds to ocular end, can obtain the light reflecting from ocular end; Light-guiding pillar 1 is also provided with U-shaped clamping part 14 in bending part 11 inner sides of L-type.

The light-guiding pillar of the present embodiment utilizes the PC material of optical grade, this light-guiding pillar material has high reflectivity and extinction not, add 90 degree bent angle designs of light-guiding pillar itself, in the situation that device structure and installing space are restricted, 90 degree turning leaded lights be can realize, flexibility and the convenience of installing increased.

Claims

1. with a binding post for 90 degree bent angle light-guiding pillars, include housing and be arranged at the light-guiding pillar in this housing, it is characterized in that: the cross section of described light-guiding pillar is inverted L-type, this L-type light-guiding pillar is arc transition at crooked bending part.

2. the binding post with 90 degree bent angle light-guiding pillars according to claim 1, is characterized in that: L-type one end opening of described light-guiding pillar is straight-tube shape and corresponds to optically focused end, and the L-type other end opening of this light-guiding pillar is back taper and corresponds to ocular end.
