Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

please refer to fig. 1-7.

The utility model discloses a transparent screen module, including protective housing 11 and PCB board 21.

The top of the protective shell 11 is opened with a receiving groove 111. Both ends of the bottom of the protective shell 11 are provided with first bulges 12, and the outer contours of the first bulges 12 are in a long strip shape. The end of the first protrusion 12 is provided with a wire connection port 121, and the wire connection port 121 is communicated with the receiving groove 111. Two waterproof grooves 122 are formed in the bottom of the protective shell 11, and the waterproof grooves 122 surround the outer sides of the first protrusions 12. The end of the first projection 12 extends out of the bottom of the protective case 11.

The middle portion of the protective casing 11 is provided with a plurality of reinforcing portions 112 arranged at intervals, preferably two reinforcing portions 112 in this embodiment, and the accommodating groove 111 penetrates through the reinforcing portions 112. The reinforcing portion 112 serves to increase the strength of the middle portion of the protective case 11. A plurality of parallel second light-transmitting grooves 113 are formed in the middle of the protective shell 11, and the second light-transmitting grooves 113 are arranged at two sides of the reinforcing portion 112 at intervals. A second protrusion 114 extends from the inner side of the second light-transmitting groove 113, and the top of the second protrusion 114 is parallel to the top of the protective case 11. A plurality of limiting columns 13 are arranged in the accommodating groove 111, four limiting columns 13 are preferably selected in the embodiment, and two limiting columns 13 are respectively close to two sides of the wiring port 121.

Steps 115 are arranged on the inner wall of the accommodating groove 111 and the side wall of the second protrusion 114, and the top of the step 115 is equal to the top of the limiting column 13 in height. The bottom of the protective shell 11 is provided with a plurality of ribs 116, and the ribs 116 are located between the two second light-transmitting grooves 113. The top of the limit column 13 extends to form a boss 131, the outside diameter of the boss 131 is smaller than that of the limit column 13, a screw hole 132 is formed in the upper end face of the boss 131, and the screw hole 132 penetrates through the protective shell 11.

Please refer to fig. 2-9.

The top of PCB board 21 is equipped with row interval arrangement and parallel lamp pearl 211, has seted up first printing opacity groove 212 on the PCB board 21 between two rows of adjacent lamp pearls 211. The two ends of the bottom of the PCB 21 are provided with pin headers 213.
