Detailed Description
The present invention will be more clearly and completely described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a multi-lamp light guide column structure for a switch according to this embodiment, fig. 2 is a side view of the multi-lamp light guide column structure for a switch according to this embodiment, fig. 3 is a schematic structural diagram of another angle of the multi-lamp light guide column structure for a switch according to this embodiment, and fig. 4 is a schematic structural diagram of the multi-lamp light guide column structure for a switch according to this embodiment when it is installed to a switch. The multi-lamp light guide column structure 100 for the switch according to the embodiment shown in fig. 1 to 4 includes a plurality of light guide columns 10 and a limiting baffle.
The light guide columns 10, the light inlet sections 12 and the light outlet sections 11 of the light guide columns 10 are formed into L shapes. The end surface of the light-entering section 12 of the light guide pillar 10 faces the LED lamp on the printed circuit board 40 (as shown in fig. 4), so that light can be transmitted to the end surface of the light-exiting section 11 via the light-entering section 12 and the light-exiting section 11 in the light guide pillar 10. The light inlet section 12 and the light outlet section 11 of the light guide pillar 10 form a slightly right-angled relationship, and the turning part has a radian.
The light guide columns 10 are arranged in a way that the light inlet section 12 and the light outlet section 11 are respectively parallel, and the arranged light inlet section 12 and the light outlet section 11 are respectively parallel to two mutually perpendicular surfaces of the cubic interface assembly 30 on the inner side of the switch. As shown in fig. 4, the interface assembly 30 and the multi-light guide post structure 100 for the switch are both secured to the printed circuit board 40, and the printed circuit board 40 is in turn secured to the housing 50 of the switch.
The limiting baffle 20 is in a flat plate shape, the limiting baffle 20 is arranged on one side of the light inlet section 12 which is parallel to each other and is opposite to the direction of the light outlet section 11 after being arranged, and is perpendicular to the light inlet section 12, and two groups of fixing pins, a fixing pin group 21, a fixing pin group 22 and a positioning pin group 23 are arranged on one side of the limiting baffle 20 which is the same as the end face of the light inlet section 12. Referring to fig. 4, that is, the position of the limit stop 20 may also be described as being disposed on the side of the light intake section 12 opposite the interface assembly 30. The fixing pin group and the positioning pin group can respectively comprise a plurality of fixing pins and positioning pins.
The fixing pins and the positioning pins are perpendicular to the limit baffle 20, the fixing pins are arranged in a direction perpendicular to the direction in which the light inlet sections 12 are arranged, the positioning pins are arranged in a direction parallel to the direction in which the light inlet sections 12 are arranged, and the positioning pin group 23 is located between the fixing pin group 21 and the fixing pin group 22.
The fixing pin can be fixed on the printed circuit board 40 by bolts or other structures such as buckles, and the positioning pin is matched with the corresponding structure such as holes on the printed circuit board 40 by means of insertion and the like. Thus, the fixing pin groups 21 and 22 fix the limit stop 20, and the arrangement direction of the fixing pins is perpendicular to the arrangement direction of the light entrance section 12, so that the light guide columns connected to the limit stop 20 are less likely to be displaced in the arrangement direction, and the plurality of fixing pins can also be less likely to be displaced in the direction perpendicular to the arrangement direction of the light guide columns.
In addition, because the locating pin group is arranged in the middle of the plurality of groups of fixing pin groups, when the plurality of light guide columns are slightly misplaced, the misplacement can be limited by the locating pins, a certain redundant space is kept, and the influence of breakage and the like on the mechanism due to the slight misplacement is avoided.
Furthermore, each group of fixing pins are connected through a rib-shaped connector, and the positioning pins 23 are connected through a rib-shaped connector. Therefore, the fixing pins and the positioning pins in one group are stressed together, and the structure is firmer.
The light-emitting sections 11 arranged in parallel are connected through a rib-shaped connector, and bosses 13 are arranged on the side faces, far away from the interface component, of the at least two light-emitting sections 11. The bosses 13 are respectively located on the second light guiding columns from outside to inside in the embodiment. Boss 13 can carry on spacingly to switch top cap (not shown in the figure) on the one hand, and on the other hand, when boss 13 received the oppression, the atress can reach the effect that alleviates leaded light post self oppression on transmitting limit baffle 20 through the kink of leaded light post.
The fixing pin groups 21 and 22 are respectively provided to both ends of the limit baffle 20 in the arrangement direction parallel to the light entrance section 12. The width of the limit baffle 20 at both ends in the arrangement direction parallel to the light inlet section 12 is greater than that at the middle. The locating pin structure with certain deformation redundancy during dislocation is located at the narrower part of the limiting baffle 20, and is helpful for relieving shearing force when stress at different angles acts on the limiting baffle.
In this embodiment, the end of the fixing pin is formed in a mushroom shape, and the positioning pin 23 is formed in a cross-sectional shape. The fixing pins are fixed by being pressed into the holes on the printed circuit board 40, and the positioning pins are inserted into the corresponding positions on the printed circuit board 40.
In addition, the limit baffle 20 is integrally formed with the light guide pole 10. The limit baffle 20 is integrally formed with the positioning pin and the fixing pin. In this embodiment, the positioning pins are one set, and the positioning pins are two sets, but in other embodiments, more sets of positioning pins or positioning pins may be used.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
