Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides an intrusion detection device for server chassis, which comprises a chassis 1, a motherboard 2 is fixedly installed at the bottom of the chassis 1, an upper cover 3 is arranged on the chassis 1, a light source detection assembly 4 and a shading component for triggering the light source detection assembly 4 are arranged in the chassis 1, and the shading component is fixedly installed at the bottom of the upper cover 3; the light blocking member is a blocking post 5. According to actual installation requirements, the light source detection component 4 is fixedly installed on the inner wall of the case 1, and can also be fixedly installed at the end part of the main board 2.

As shown in fig. 2, the light source detecting assembly 4 includes a U-shaped housing 6, and the U-shaped housing 6 is opened upward. The first end of U type casing 6 is equipped with photoemitter 7, and the second end of U type casing 6 is equipped with photoelectric receiver 8, and the bottom of U type casing 6 is equipped with detection circuit board 9, photoemitter 7 and photoelectric receiver 8 set up relatively. The blocking column 5 is used for blocking a light signal sent by the photoelectric emitter 7 to the photoelectric receiver 8, the blocking column 5 is arranged right above the U-shaped shell 6, the top of the blocking column 5 is fixedly connected with the bottom of the upper cover 3, and the bottom of the blocking column 5 is arranged in an opening of the U-shaped shell 6.
