Technical Field

[0002] The 1394B bus, also known as Firewire, is a high-speed serial interface standard. The 1394B bus is often used to connect digital video devices, such as cameras and video recorders, to achieve high-speed, high-quality video data transmission.

[0003] To ensure the performance of the 1394B bus, quality testing is often required before use or after manufacturing. Bit error rate (BER) testing equipment can detect the BER during transmission, thereby assessing the bus's transmission quality and reliability. A test port of the BER testing equipment is connected to the onboard 1394B bus via an adapter cable to form a test channel. Then, the BER analysis equipment sends test signals through the test port and determines whether the BER of the 1394B bus meets the requirements based on the test signals. The BER testing equipment generates heat during use, and to ensure its effectiveness, the cover is periodically removed for maintenance. However, existing BER testing equipment has insufficient heat dissipation, making it inconvenient to disassemble and reassemble the unit and cover. The problems with the above technology are: insufficient heat dissipation performance of the BER testing equipment, often relying on natural ventilation; inability to quickly disassemble and reassemble the unit and cover; and difficulty in adjusting the overall height for use.

[0026] The working principle of this utility model:

[0027] When heat dissipation is required, the two fans 202 are activated to exhaust the heat generated inside the body 101, thereby improving the heat dissipation effect of the body 101. The air passes through the dust filter 204, which traps dust. When the dust filter 204 needs to be removed for cleaning, the two connecting pins 504 are manually pushed to move towards opposite ends, causing the two connecting pins 504 to move out of the inside of the two connecting blocks 501. At this time, the dust filter 204 can be pulled to the left to disengage from the fixing part 201. When the height of the body 101 needs to be adjusted... Remove the bolts that fix the sliding member 302 and the slider 301. At this time, the sliding member 302 drives the base plate 303 to move upward or downward, and the sliding member 302 and the slider 301 are fixed by the corresponding bolts. When it is necessary to separate the machine body 101 from the cover plate 102, the push plate 404 is pulled downward by hand and the moving block 402 is moved downward. The moving block 402 will cause the two positioning blocks 403 to move downward and move out of the inside of the insertion port 6 and the insertion plate 7 in sequence. At this time, the cover plate 102 can be moved backward and disengaged from the machine body 101.
