Description

Technical Field

[0001] The utility model relates to the technical field of optical terminal equipment, in particular to a multi-channel HDMI optical terminal equipment. Background Art

[0002] Optical terminal is the transmission equipment in the optical communication system. It is mainly used for photoelectric conversion and transmission. It is generally used for telecommunications, power, monitoring, industrial control, video transmission and other functions. It is widely used in various industries. The commonly said optical terminal refers to the optical terminal used in the monitoring system to transmit video, data, Ethernet, audio and other comprehensive information. It is mainly divided into analog optical terminal and digital optical terminal. Based on the different transmission media, there are single-mode optical terminal and multi-mode optical terminal. Due to the improvement of technology and the reduction of optical fiber price, it has been well applied in various fields, mainly reflected in security monitoring. Therefore, various optical terminal manufacturers have sprung up like mushrooms after rain, but most of the manufacturers' technology is not fully mature, and various brands have appeared one after another.

[0003] In the prior art, the common interface of optical terminals is often HDMI. However, due to the different environments in which optical terminals are used, if their interfaces are not protected for a long time, dust will accumulate at the interfaces of HDMI devices. When the interfaces are connected to HDMI cables, signal transmission cannot be performed.

[0004] After searching, it is found that a Chinese patent document discloses an HDMI dustproof optical terminal (publication number: CN220528059U). The utility model discloses an HDMI dustproof optical terminal, which belongs to the field of dustproof technology of optical terminals, and includes an optical terminal body, wherein a slot is provided inside the optical terminal body, and a plug is placed outside the optical terminal body, and the plug and the slot cooperate with each other. The advantage of the utility model is that when the optical terminal is not in use with extra slots, the baffle will cover the slot due to gravity, thereby reducing the possibility of dust entering through the slot. When the plug is inserted, the plug can push the tooth thrust column to move, thereby causing the transmission shaft and the transmission gear to rotate, and the rack is moved by the rotation of the transmission gear. At this time, the movement of the rack is used to move the cleaning plate in the cleaning slot, thereby pushing the dust in the cleaning slot to the outside of the slot. In this way, the dust falling in the slot can be cleaned to the outside of the slot when the plug is inserted, thereby further increasing the dustproof effect of the optical terminal. However, there are still the following defects:

[0005] The above-mentioned HDMI dustproof optical terminal realizes that when the extra slots of the optical terminal are not in use, the baffle will cover the slots due to gravity, thereby reducing the possibility of dust entering through the slots. When the plug is inserted, the plug can push the tooth thrust column to move, thereby causing the transmission shaft and the transmission gear to rotate, and the rack is moved by the rotation of the transmission gear. At this time, the movement of the rack is used to move the cleaning plate in the cleaning groove, thereby pushing the dust in the cleaning groove to the outside of the slot. In this way, the dust fallen in the slot can be cleaned to the outside of the slot when the plug is inserted, thereby further increasing the dustproof effect of the optical terminal. However, this method still needs to change the interface of the optical terminal, which will change the structure of the circuit board and other structures of the optical terminal, which is not easy to mass produce and will also create severe processing requirements for existing processing equipment.
