Description

Light guide structure of the connector

technical field

The utility model relates to a light guiding structure of a connector.

Background technique

Press, the light guide unit 5 (as shown in Figure 1 and Figure 2) of the commonly used connector, it is made of more than one light guide column 51, and each light guide column 51 is the material that can transmit light; It is combined with the housing of the connector, and each light guide column 51 of the light guide unit 5 is used to guide the light source.

But, because each light guide column 51 is the material that can transmit light, therefore, when the light source of illuminant 6 is guided by the light guide column 51 on one side (left side or right side) of light guide unit 5, just can make The light source is lost in the conduction path of the light guide column 51, and part of the light source is received by the light guide column 51 that does not emit light, so that the light guide column 51 on the other side is disturbed by the light source transmission, and the end of each light guide column 51 that emits light The light source is emitted, causing misjudgment by the user; in addition, when the light guide rods 51 on both sides of the light guide unit 5 guide the light source at the same time, the light sources of each illuminant 6 will be passed through the conduction path of each light guide rod 51 Lost, so that each light guide column 51 interacts with each other, and the light source emitted by the light-emitting end of each light guide column 51 cannot guide the light source stably and reliably due to the loss during transmission, resulting in only one end of each light guide column 51. The weak light source cannot meet the needs of practical use.

Therefore, the current problem to be solved is how to create a light guiding structure of the connector so that it can achieve the effect of stably and reliably guiding the light source and avoiding misjudgment by users.

Utility model content

The technical problem to be solved by the utility model is to provide a light guide structure of the connector, which can be combined with the housing of the connector, and use the light guide columns of the light guide unit to guide the light source, so that each The light guide column can use the cooperation of the shielding unit to avoid the mutual interference of the light sources in the transmission path of each light guide column, and prevent the light source from being lost, so as to achieve the purpose of guiding the light source stably and reliably and avoiding misjudgment by the user.

In order to solve the above problems, the light guide structure of the connector of the present invention includes: a light guide unit having more than one light guide column, each light guide column has a light incident part and a light output part at both ends; The shielding unit outside the beam.

Compared with the prior art, the utility model provides a light guide structure of the connector, which can be combined with the housing of the connector, and use the light guide columns of the light guide unit to guide the light source, so that each The light guide column can use the cooperation of the shielding unit to prevent the light sources from interfering with each other in the transmission path of each light guide column, and can prevent the light source from being lost, so as to achieve the effect of stably and accurately guiding the light source and avoiding misjudgment by the user.

Detailed ways

In order to fully understand the purpose, features and effects of the present utility model, the utility model is described in detail through the following specific embodiments in conjunction with the attached drawings, as follows.

Please refer to "Fig. 3 and Fig. 4", which are respectively the appearance diagram of the utility model and the partial enlarged schematic diagram of part A in Fig. 3 of the utility model. As shown in the figure: the light guiding structure of the connector of the present invention at least includes a light guiding unit 1 and a shielding unit 2.

The light guide unit 1 mentioned above has more than one light guide column 11, each light guide column 11 has a light incident portion 111 and a light output portion 112 at both ends, and the bottom surface of the light guide unit 1 is provided with a fastening portion 12.

The shielding unit 2 is coated on the outside of each light guide column 11 of the light guide unit 1, and the shielding unit 2 at least includes a reflective layer 21 coated on the outside of each light guide column 11, and a light absorbing layer stacked on the reflective layer 21. Layer 22, the reflective layer 21 can be made of aluminum or silver, and the light-absorbing layer 22 can be colored paint.

Please refer to "Figure 5, Figure 6, Figure 7, Figure 8, and Figure 9", which are respectively the first use state diagram of the present utility model, the light source conduction state diagram of the present utility model, and another light source conduction state of the present utility model Figure, the second usage state diagram of the utility model and the third usage status diagram of the utility model. As shown in the figure: when the utility model is in use, take a light guide unit 1 and combine it with the connector housing 3 (as shown in Figure 5), and use the fastening part 12 at the bottom of the light guide unit 1 to combine On the connector housing 3, as a guide light source, two, four or more light guide units 1 can be combined with different connector housings 3a and 3b as required (as shown in Fig. 8 and Fig. 9) for the use of light guide.

And when using the light guide column 11 on one side (left or right side) of the light guide unit 1 to guide (as shown in Figure 6), the light source of the illuminant 4 enters through the light incident part 111 of the light guide column 11. Then it is led out by the light exit part 112. Since the light guide column 11 is covered with the shielding unit 2, when the light source enters from the light entrance part 111, the light source of the luminous body 4 is covered by the cooperation of the reflective layer 21 and the light absorption layer 22. It is reflected and sealed in the conduction path inside the light guide column 11, and then led out by the light exit portion 112. In this way, the cooperation of the shielding unit 2 can be used to prevent the light source of the illuminant 4 from being lost in the conduction path, so that the light exit portion 112 can The light source is guided stably and reliably, so as to prevent the light guide column 11 on the other side from being interfered by the light source transmission, and to prevent misjudgment by the user.

Secondly, when using the light guide columns 11 on both sides of the light guide unit 1 for guidance (as shown in Figure 7), the light sources of the two luminous bodies 4 are respectively entered by the light incident portions 111 of the light guide columns 11, and the reflective layer 21 cooperates with the light-absorbing layer 22 to reflect the light source of each illuminant 4 and seal it in the conduction path inside each light-guiding column 11, and then guide it out from each light-exiting part 112.
